SQL Data Compare 10

Example - selecting single tables for comparison

This example illustrates how you select a single table for comparison.

In this example, the databases contain the following tables (amongst others):

  • Product
  • ProductCategory
  • ProductCostHistory
  • ProductDealerPriceHistory
  • SpecialOfferProduct

You are interested only in the differences between the Product tables in two different versions of your database; you are not interested in any of the other tables or views in the databases.

Using the command line

To specify the table to include, you use the /Include switch:

sqldatacompare /db1:Products1 /db2:Products2
     /Include:table:[Product] /verbose

where:

  • /db1:Products1
    specifies that you want to compare the database Products1
  • /db2:Products2
    specifies that you want to compare the database Products2
  • /Include:table:\[Product\]
    specifies that you want to compare only the table that has a name that includes the string [Product]
  • /verbose
    specifies that you want to display detailed information about differences between objects
Note that you use .NET standard regular expressions to define the /Include and /Exclude arguments. Therefore, you must escape the square brackets ( [ ] ) with the backslash character ( \ ). Regular expression syntax is beyond the scope of this online help; refer to your Microsoft .NET framework documentation for more information.

You must include the brackets ( [ ] ) in the string; if you specify the argument without the brackets, /Include:table:Product, the ProductCategory table is included because it contains the string Product. The full SQL Server table names are qualified by the owner name in SQL Server 2000, and the schema name in SQL Server 2005/2008, and include brackets. For example (in SQL Server 2000):

[dbo].[Product]
[dbo].[ProductCategory]

and so on. Therefore, the brackets indicate that you are specifying the full table name. To include the owner (or schema) name in the regular expression, you would need also to escape the dot ( . ):

/Include:table:\[dbo]\ .\[Product\]

The pipe character ( | ) in a regular expression is interpreted as a logical OR. The character must be escaped by the caret character ( ^ ), to prevent the operating system shell from interpreting it as the pipe operator. (Note that if you want to use the caret character itself as part of your regular expression, it must be escaped by a second caret.)

Using XML

You can use XML as follows:

<?xml version="1.0"?> <commandline>
<database1>Products1</database1>
<database2>Products2</database2>
<verbose/>
<include>Table:[Product]</include>
</commandline>

To execute the comparison using the XML file, enter the following command:

sqldatacompare /Argfile:xmlfilename.xml

where xmlfilename is the name of the XML file.
