Setting IQ Connection Level Option Preferences

Specify default values for the launch configuration of newly created Sybase IQ procedural objects and for the SQL Editor. Set these preferences in Window|Preferences|Connection Level Options, on the Sybase IQ_12.6.x tab. These settings apply to Sybase IQ_12.5.x also.

Note

Connection Level options are server settings.

Connection Level Options: Arithmetic

Field	Explanation
Ansi integer overflow	Click for integer overflow errors to cause a SQLSTATE = 22003 - overflow error (SQL/92 behavior). Default is OFF.
Divide by zero	Click for division by zero to report an error with SQLSTATE 22012. Do not click to return NULL. Default is ON.

Connection Level Options: On TSQL Error

Field	Explanation
On TSQL Error	Select error handling action for stored procedures: Stop — Stop execution immediately when an error occurs. Continue — Always continue execution. If there are multiple errors, the first error found is returned. Conditional — If the procedure uses ON EXCEPTION RESUME, and the statement after the error handles the error, continue. Otherwise exit. Default.
