Consider the following scenario:

  • You create a database project by using Microsoft Visual Studio 2008.

  • You connect to a database and then add a new query.

  • You type an SQL statement that resembles the following in the SQL pane:

    SELECT ‘<column 1>’ FROM ‘<table>’ WHERE @parameter <= ‘<column 2>’

  • You move the cursor out of the SQL pane to parse the statement.

In this scenario, the SQL statement is parsed as follows:

SELECT ‘<column 1>’ FROM ‘<table>’ WHERE (‘<column 2>’ > @parameter)

Notice that the equal sign (=) in the Less Than or Equal To operator (<=) is missing from the SQL statement. This problem also occurs when the operator is Greater Than or Equal To (>=).

Note This same problem occurs in Microsoft SQL Server Management Studio 2008 and Microsoft SQL Server Management Studio 2008 R2.
