![PRESERVE_SOURCE_FORMAT option [database]](arrow-left.gif){kind=icon}
Specifies whether or not to include additional query information in the Query Detail section of the query plan.
ON, OFF
OFF
DBA permissions are not required to set this option. Can be set temporary for an individual connection or for the PUBLIC group. Takes effect immediately.
When QUERY_DETAIL and QUERY_PLAN (or QUERY_PLAN_AS_HTML) are both turned on, Sybase IQ displays additional information about the query when producing its query plan. When QUERY_PLAN and QUERY_PLAN_AS_HTML are OFF, this option is ignored.
When QUERY_PLAN is ON (the default), especially if QUERY_DETAIL is also ON, you might want to enable message log wrapping or message log archiving to avoid filling up your message log file. For details, see “Message log wrapping” in Chapter 1, “Overview of Sybase IQ System Administration” of the System Administration Guide: Volume 1.
