When you copy a SQL statement from the SQL Scanner to the SQL Optimizer module, the Send to SQL Optimizerfunction automates this process for you. It copies the SQL statement, opens the SQL Optimizer window and inserts the SQL statement in the SQL Editor pane. When the SQL statement you are copying also includes a temporary table, the Send to SQL Optimizer function also copies the SQL statements for creating and populating the temporary table to the User-Defined Temp Table module.
Two items need to be considered when the SQL statements are automatically copied in the User-Defined Temp Table module. Is there SQL text already in the module? And does the temporary table already exist with the same or different data?
If SQL text is already entered into the User-Defined Temp Table module, you are prompted to save the current SQL to an ASCII file before it is overlaid with the new text. Saving the text enables you to use it again.
If a table with the same name already exists and you would like to recreate it with either a new definition or different data, then you must drop the table before executing the new SQL text. You can drop temporary table from the Temp Table List tab in the User-Defined Temp Table module.
