Optionally, you can add the data to the Data Model so that you can combine your data with other tables or data from other sources, create relationships between tables, and do much more than you can with a basic PivotTable report. Then, in the Import Text File dialog box, double-click the text file that you want to import, and the Text Import Wizard dialog will open.

Original data type If items in the text file are separated by tabs, colons, semicolons, spaces, or other characters, select Delimited. If all of the items in each column are the same length, select Fixed width.

Start import at row Type or select a row number to specify the first row of the data that you want to import. File origin Select the character set that is used in the text file. In most cases, you can leave this setting at its default. If you know that the text file was created by using a different character set than the character set that you are using on your computer, you should change this setting to match that character set.

For example, if your computer is set to use character set Cyrillic, Windows , but you know that the file was produced by using character set Western European, Windows , you should set File Origin to Preview of file This box displays the text as it will appear when it is separated into columns on the worksheet.

Delimiters Select the character that separates values in your text file. If the character is not listed, select the Other check box, and then type the character in the box that contains the cursor. These options are not available if your data type is Fixed width. Treat consecutive delimiters as one Select this check box if your data contains a delimiter of more than one character between data fields or if your data contains multiple custom delimiters.

Text qualifier Select the character that encloses values in your text file. When Excel encounters the text qualifier character, all of the text that follows that character and precedes the next occurrence of that character is imported as one value, even if the text contains a delimiter character.

For example, if the delimiter is a comma , and the text qualifier is a quotation mark ” , “Dallas, Texas” is imported into one cell as Dallas, Texas. If no character or the apostrophe ‘ is specified as the text qualifier, “Dallas, Texas” is imported into two adjacent cells as “Dallas and Texas”.

If the delimiter character occurs between text qualifiers, Excel omits the qualifiers in the imported value. If no delimiter character occurs between text qualifiers, Excel includes the qualifier character in the imported value.

Hence, “Dallas Texas” using the quotation mark text qualifier is imported into one cell as “Dallas Texas”. Data preview Review the text in this box to verify that the text will be separated into columns on the worksheet as you want it. Data preview Set field widths in this section. Click the preview window to set a column break, which is represented by a vertical line.

Double-click a column break to remove it, or drag a column break to move it. Specify the type of decimal and thousands separators that are used in the text file. When the data is imported into Excel, the separators will match those that are specified for your location in Regional and Language Options or Regional Settings Windows Control Panel.

Column data format Click the data format of the column that is selected in the Data preview section. If you do not want to import the selected column, click Do not import column skip. After you select a data format option for the selected column, the column heading under Data preview displays the format.

If you select Date , select a date format in the Date box. Choose the data format that closely matches the preview data so that Excel can convert the imported data correctly. To convert a column of all currency number characters to the Excel Currency format, select General. To convert a column of all number characters to the Excel Text format, select Text.

To convert a column of all date characters, each date in the order of year, month, and day, to the Excel Date format, select Date , and then select the date type of YMD in the Date box. Excel will import the column as General if the conversion could yield unintended results. If the column contains a mix of formats, such as alphabetical and numeric characters, Excel converts the column to General. If, in a column of dates, each date is in the order of year, month, and date, and you select Date along with a date type of MDY , Excel converts the column to General format.

A column that contains date characters must closely match an Excel built-in date or custom date formats. If Excel does not convert a column to the format that you want, you can convert the data after you import it. Convert numbers stored as text to numbers. Convert dates stored as text to dates. TEXT function. VALUE function.

When you have selected the options you want, click Finish to open the Import Data dialog and choose where to place your data. Set these options to control how the data import process runs, including what data connection properties to use and what file and range to populate with the imported data. The options under Select how you want to view this data in your workbook are only available if you have a Data Model prepared and select the option to add this import to that model see the third item in this list.

If you choose Existing Worksheet , click a cell in the sheet to place the first cell of imported data, or click and drag to select a range. If you have a Data Model in place, click Add this data to the Data Model to include this import in the model. For more information, see Create a Data Model in Excel. Note that selecting this option unlocks the options under Select how you want to view this data in your workbook.

Click Properties to set any External Data Range properties you want. For more information, see Manage external data ranges and their properties. In the New Web Query dialog box, enter the address of the web page you want to query in the Address box, and then click Go. In the web page, click the little yellow box with a red arrow next to each table you want to query. None The web data will be imported as plain text. No formatting will be imported, and only link text will be imported from any hyperlinks.

Rich text formatting only The web data will be imported as rich text, but only link text will be imported from any hyperlinks. This option only applies if the preceding option is selected. If this option is selected, delimiters that don’t have any text between them will be considered one delimiter during the import process.

If not selected, the data is imported in blocks of contiguous rows so that header rows will be recognized as such. If selected, dates are imported as text. SQL Server is a full-featured, relational database program that is designed for enterprise-wide data solutions that require optimum performance, availability, scalability, and security. Strong password: Y6dh! Weak password: house1. Passwords should be 8 or more characters in length.

Under Select the database that contains the data you want , select a database. Under Connect to a specific table , select a specific table or view. Alternatively, you can clear the Connect to a specific table check box, so that other users who use this connection file will be prompted for the list of tables and views. Optionally, in the File Name box, revise the suggested file name. Click Browse to change the default file location My Data Sources.

Optionally, type a description of the file, a friendly name, and common search words in the Description , Friendly Name , and Search Keywords boxes. To ensure that the connection file is always used when the data is updated, click the Always attempt to use this file to refresh this data check box. This check box ensures that updates to the connection file will always be used by all workbooks that use that connection file.

To specify how the external data source of a PivotTable report is accessed if the workbook is saved to Excel Services and is opened by using Excel Services, click Authentication Settings , and then select one of the following options to log on to the data source:.

Windows Authentication Select this option to use the Windows user name and password of the current user. This is the most secure method, but it can affect performance when many users are connected to the server. A site administrator can configure a Windows SharePoint Services site to use a Single Sign On database in which a user name and password can be stored. This method can be the most efficient when many users are connected to the server.

None Select this option to save the user name and password in the connection file. Security Note: Avoid saving logon information when connecting to data sources. Note: The authentication setting is used only by Excel Services, and not by Excel.

Under Select how you want to view this data in your workbook , do one of the following:. To place the data in an existing worksheet, select Existing worksheet , and then type the name of the first cell in the range of cells where you want to locate the data. Alternatively, click Collapse Dialog to temporarily collapse the dialog box, select the beginning cell on the worksheet, and then click Expand Dialog.

To place the data in a new worksheet starting at cell A1, click New worksheet. Optionally, you can change the connection properties and also change the connection file by clicking Properties , making your changes in the Connection Properties dialog box, and then clicking OK.

If you are a developer, there are several approaches within Excel that you can take to import data:. You can use Visual Basic for Applications to gain access to an external data source.

You can also define a connection string in your code that specifies the connection information. Using a connection string is useful, for example, when you want to avoid requiring system administrators or users to first create a connection file, or to simplify the installation of your application.

WriteXml System. XmlWriter writer. Well, it is obvious that we could use the To… functions to convert the resulting decimal value to some other sub datatypes. Well, there is one reason in the world of databases that is incompatible to the type system of most other programming or script languages and always requires special treatment: Null values!

In most traditional programming languages special functions have been introduced to test for nullable values. That said, our new query does work for us, but hey, we only received one value where three values should be available: intCount , strCount , and datCount!

The solution is rather obvious so we can simply add two statements after the GetOracleDecimal call:. We can query rather complex Oracle result sets now! What about receiving several rows as result of a query?

Of course, we could add this in a one liner by using a constant string, which is not the way I would like to do that! IsKey :. DataType : System. IsLong : False.

Along with a whole bunch of other valuable information about our data columns, we can access the ColumnName property:. If we can retrieve the column names, we may come up with a nice header line after some formatting:. We would prefer to have objects here and let Windows Powershell do all the formatting for us.

GetOracleDecimal 0. GetOracleString 1. GetOracleDate 2. Additionally, the filtering and sorting capabilities of a data grid view are now for free. I did exchange the data reader with a data adapter, which has a Fill method that can automatically populate a dataset or data table with the results of the select statement. This is at least a timesaver writing the script code. A rather interesting question came to mind now: Is it a timesaver regarding performance, too? Well, we probably should do some testing now.

But measuring the execution time of the select command is most likely faulty if we just execute one select. Maybe 10 selects would provide a better measurement basis and retrieving more than 10 rows, maybe , might be better, too. To do so, we are getting a bit more Windows Powershell-stylish now and encapsulate the two scripts in functions.

But we should definitely consider some more changes. The new versions of the script might look even better if we parameterize the select statement and probably the connection string, too! Additionally, the use of a constant connection string is not the best solution. I added rudimentary error checking and a very simple checking on both input parameters, too. We just set the whole function inside a try-catch-finally block to catch and report any errors that are likely to happen during database operations.

I mentioned above that it might be necessary to do some repetitions if you want to measure the execution time of each command to get a feeling for the performance of both procedures, but, in fact, it is rather obvious that the first command lasts longer than the second does. However, measure the time for 10 loops of each command now. Instead of the last two lines, do the following:. And definitely wrong, as I can tell you from my experience! But I can explain to you that each database relies on heavy, well elaborated, and highly tuned caching algorithms that prevent a reasonable timing if you loop through the same statement.

The statement is preparsed and cached, the previously calculated execution plan is used again and if result set caching is available, the execution may be skipped at all, and the old result set will just be returned to the client. So, we will have to clear the buffer cache and shared pool before we can execute each statement once, if we really would like to have reasonable timing data for at least one execution of each statement.

Days : 0. Hours : 0. Minutes : 0. Seconds : 2. Ticks : TotalDays : 2,E TotalHours : 0, Seconds : 0. TotalDays : 3,E TotalHours : 8,E These data are more realistic!

But still the data adapter is ready in 0. Is it real that the data adapter received the results 7 to 8 times faster than the reader?

Very unlikely, I would say. I will flush the database cache each time before I test the statement. We can definitely expect that most of the time if used inside the loop:. It may be that they are slowing the operation down:. Well, this is not too bad at all! It seems to be even faster than the preceding measurement, which is, of course, hardly possible.

It is more or less a result of inaccurate timing for such fast operations. Even if we consume the data, we are still pretty fast getting at the results! So what else could be the reason why? No remarkable changes, too! No significant change, but the objects were empty! At least partially. We found the slow operation: Adding members to the PsCustomObject seems to be very time consuming.

Comparing it to the original 2. This would be an improvement that Windows Powershell offers for free! It is less coding and less failure and as we have seen here less execution time! Back to the main insight now: Adding members to our object is slowing the function down! The final question is: Do we have alternative ways to build object and are they faster? Well, we can build objects like this in Windows Powershell:. GetOracleDecimal 0 ;.

GetOracleString 1 ;. GetOracleDate 2 ;. This seems to make a difference, too. It is still faster than Add-Member , but slower than the second solution … at least in this case. But wait! There is still another new solution available in Windows Powershell 3. We have the new [pscustomobject] type accelerator available now:. The last thing I want to do now is to generalize the solution a little further! We still have used a special query up to now that returns three values in each row with fixed data types: OracleDecimal , OracleString , and OracleDate.

This is very special and the question arises if we can modify the solution further to accept other types of data and more or less than three columns per row. Of course, we can but as a constructor of a [pscustomobject] with variable initial values is not available, can we still profit the fastest solution or will we have to go back to the Add-Member solution, which is very slow? GetSchemaTable , where this information is part of the row description:.

But even if we had the type information, we would further have to use this information in a switch statement to retrieve the function call that is appropriate for the current field type. This is not fun! But wait, there is an easier way out! We can use the type neutral function:.

Object GetOracleValue int i. Nicely enough, the field count is a property of the data reader:. This way we can use the fast constructor but have a variable initialization. In fact, we are back to where we started from: We have a time of over 2 seconds again. A little additional overhead would be OK, if we can generalize queries. But is it really true that we are back to where we started from? I really thought so at first but investigating things further I discovered that the loop construct followed by the pipe is quite slow.

This is quite acceptable for a generalized solution! Something to remember! If you are not convinced that it really does what it is supposed to do, we can supply some alternative queries just to present the results. Here is result of a query that returns the Fibonacci numbers and the depth level of the recursion or just a counter if you prefer that. In easy words: Start with two numbers 0 and 1. You may notice that calculating the last values takes a noticeable amount of time.

Just one last remark. There is also an iterative solution available that is by far faster, of course, as shown here:. And I can tell you that this statement runs in nearly no time, too!

It is usually available to each user. The results are looking good but maybe you expected that the order of the displayed columns should be different according to the select statement. If you need to keep the order, you can pipe the result to Select-Object and enumerate the fields in the right order:.

Why exactly could the order of the columns not be preserved? And here is something new in Windows Powershell 3. Adding the [ordered] tag as part of the creation of the hashtable does do the job. So reordering the result by Select-Object is no longer needed.

So, we have retrieved three OracleDecimals , two OracleStrings , and one OracleDate here, which is quite close to what you might have guessed. True False DataRow System. And even the types are not identical, though similar:. It just returns the corresponding. NET types. Back to our original question: Is the data adapter faster than the data reader?

Yes, it looks like that. And that is an observation that is even opposite to some articles I have read before. We had 0, seconds for the data adapter, and now we still have 0, seconds for the data reader, which is small, but in recurring queries and maybe if larger result sets have to returned, significant difference! If you think: Why should I bother? I will always use the data adapter that returns a ready to use dataset or a data table with less coding in a smaller amount of time?

First of all: I am not sure if it may not be possible to tune the data reader further with special database parameters like the fetchsize to make it even faster. The data reader can be used to serially progress each data row, the data adapter has to fetch all the data before you can progress any row.

One other thing to remember is that you have a permanent connection to the database while you use the data reader to fetch each row. You have to manually open and close the connection before you start reading the data and after you finished to do so. The data adapter does this behind the scenes in its fill-method for you.

It only connects to the database to populate the data set or table used to keep the results of the query. In fact I did check with the still available, though deprecated, version of the Microsoft implementation of the Oracle client.

If you still want to use it, you may have to load the assembly if you are using the. NET 4 client profile. Other necessary changes include replacing Oracle. Client with System. OracleClient and using a different connection string. The results have been pretty much the same as those that we have seen before using the managed Oracle data provider! Using the Oracle OleDb provider requires that it is registered on your local machine. If you have to register any of the two versions, pay attention of the regsvr Otherwise, we may have encountered error messages reporting that the Oracle.

OleDb provider is not registered on the local machine. The changes to the script required to use the OleDb provider are very little: We have to replace each occurrence of the string Oracle.
