Default Dynamically Changing SQL Commands?

I have developed an ASP.NET application that uses an “SQL Command” as described in the section “Working with SQL Commands" on page 181. I need to be able to change that command programmatically at runtime but I can’t find a way to do it. The change I would make would be to the WHERE clause, and the resulting table would have the same format as that specified in the report designer. Is there a way to alter the SQL Command programmatically, on the fly, at runtime?

Thank you…

Jerry

Hey,

Sure you can dynamically build a command. It sounds like you're creating dynamic SQL though; so none of the SQL queries can be predefined in advanced? If not, you can use string manipulation or regular expressions to parse apart the SQL string.

strSQL = strSQL.Substring(0, strSQL.indexOf(" WHERE "))

OR

' \. means any characters, and the + means one or more
strSQL = Regex.Replace(strSQL, " WHERE \.+", "")

Something like that,

Brian
