SQL Compare 11

Example - selecting single tables for comparison

This shows how you can use the command line or an XML arguments file to 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 schema differences between the Product tables in two different versions of your database; you are not interested in any of the other tables, or any other objects in the database.

You can replace the database (/db) in this example with either a scripts folder (/scr) or a snapshot (/sn) and the example will still work correctly. For more information, see: Simple examples using the command line.

Using the command line

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

sqlcompare /db1:Products1 /db2:Products2 /Include:table /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 specifies that you want to compare only tables; you do not want to compare other objects such as views, stored procedures, and so on. If you omit this argument, SQL Compare compares all tables that have names that match the second /Include switch and all other objects in the databases.

To specify more than one object type for inclusion, use multiple /include switches. For example, to include only tables and views, enter:

/Include:table /Include:view

/Include:table:\[Product\] specifies that you want to compare only the table that has a name that includes the string[Product]

Because you use .NET standard regular expressions to define the /Include and /Exclude arguments, 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, theProductCategory 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. (If you want to use the caret character itself as part of your regular expression, it must be escaped by a second caret.)

/Verbose specifies that you want to display detailed information about differences between objects

Using XML

You can use XML like this:

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

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

sqlcompare /Argfile:XMLFileName.xml

where XMLFileName is the name of the XML file.
