How to use a SQL statement to control a block of C# statements

rmmarsh asked
Last Modified: 2010-04-15
Using the following statement:

            commandString = "IF NOT EXISTS(SELECT 1 FROM syscolumns WHERE name = 'SubCatID')"

Is there a way that I can use this partial statement to control C# statements that follow?  (kind of an IF followed by a block of C# statements).  I want to be able to alter a table to a new format if the table has not been altered before.  It's not a simple job, because I have to backup the old table data, delete the old table, create a new table and then restore some of the data.
