You set options with the SET OPTION statement. It has the following general syntax:
SET [ EXISTING ] [ TEMPORARY ] OPTION ... [ userid. | PUBLIC. ]option-name = [ option-value ]
Specify a user ID or group name to set the option only for that user or group. Every user belongs to the PUBLIC group. If no user ID or group is specified, the option change is applied to the currently logged on user ID that issued the SET OPTION statement.
For example, the following statement applies a change to the PUBLIC user ID, a user group to which all users belong.
SET OPTION Public.login_mode = standard
For all database options that accept integer values, Sybase IQ truncates any decimal option-value setting to an integer value. For example, the value 3.8 is truncated to 3.
The maximum length of option-value when set to a string is 127 bytes.
WARNING! Do not change option settings while fetching rows.
