Action available for the following operating systems:
Execution mode
Online - The query will be executed in the specified Database.
Database Connection Profile - Database Connection Profile where the query will be executed. It's not mandatory to have tables defined in the profile to be able to run this Action.
Offline - The query will be executed in the Local Database which holds all the offline Tables.
Clear Target When No Data is Returned - If this option is checked and no record is returned, all the Targets are cleared.
SQL Sentence <string> - SQL query to perform.
Targets
Column <unquoted string> - Name of the column to retrieve. This parameter is merely informative and has no impact whatsoever. What matters is the index of the Column. Therefore, this refers to the first returned Column.
Target <target> - Control or Variable where to save the value of the first Column.
nth Column <unquoted string> - Name of the column to retrieve. This parameter is merely informative and has no impact whatsoever. What matters is the index of the Column. Therefore, this refers to the nth returned Column.
nth Target <target> - Control or Variable where to save the value of the nth Column.
Consider the following Database Table, and the following Variables:
