Remove SQL command string from DocumentCreateReadSQL

This commit removes a SQL command string from the `Raw` property in the `DocumentCreateReadSQL` class. The changes include the deletion of a `USE` statement for the `[DD_ECM]` database, variable declarations, and the execution of a stored procedure. This alters the structure and execution of SQL commands within the class.
