Purpose
Prints the last SQL request sent to the database to the standard output stream.
Syntax
Usage Notes
Use the .SHOW command to display the last SQL request that was sent to database. The .SHOW command can be used even if ECHOREQ is set to OFF.
You can use the SHOW command in an SQL macro. However, note that if a "ECHO '.SHOW';" SQL is used in a macro, that actually becomes the “last” SQL request, in which case, the SHOW command would always return "ECHO '.SHOW';" itself.
The only way to get the last SQL request using SHOW command in a macro is to use the "ECHO'.SHOW';" SQL in a multi-statement request.
