Logging parameters can be set in the SQL Explorer preferences page or using the following syntax:
${set option-name} On|OffPossible option-name's are:
-- ${set LOG_SQL} Off
-- ${set LOG_SUCCESS} On
Structured comments are processed before executing any SQL. Therefore these settings apply to the whole executing block (file or marked text).
'${set' structured comments do not change the values set in the preference page. They allow to switch them temporarily in SQL files.
