Server System Variables Maximum Value 30 This variable indicates the number of digits by which to increase the scale of the result of division operations performed with the  /  operator. The default value is 4. The minimum and maximum values are 0 and 30, respectively. The following example illustrates the effect of increasing the default value. mysql>  SELECT 1/7; +--------+ | 1/7 | +--------+ | 0.1429 | +--------+ mysql>  SET div_precision_increment = 12; mysql>  SELECT 1/7; +----------------+ | 1/7 | +----------------+ | 0.142857142857 | +----------------+ • dragnet.log_error_filter_rules Command-Line Format --dragnet.log-error-filter- rules=value System Variable dragnet.log_error_filter_rules Scope Global Dynamic Yes SET_VAR  Hint Applies No Type String Default Value IF prio>=INFORMATION THEN drop. IF EXISTS source_line THEN unset source_line. The filter rules that control operation of the  log_filter_dragnet  error log filter component. If  log_filter_dragnet  is not installed,  dragnet.log_error_filter_rules is unavailable. If  log_filter_dragnet  is installed but not enabled, changes to dragnet.log_error_filter_rules  have no effect. The effect of the default value is similar to the filtering performed by the  log_sink_internal  filter with a setting of  log_error_verbosity=2 . As of MySQL 8.0.12, the  dragnet.Status  status variable can be consulted to determine the result of the most recent assignment to  dragnet.log_error_filter_rules . Prior to MySQL 8.0.12, successful assignments to  dragnet.log_error_filter_rules  at runtime produce a note confirming the new value: mysql>  SET GLOBAL dragnet.log_error_filter_rules = ’IF prio <> 0 THEN unset prio.’; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql>  SHOW WARNINGS\G *************************** 1. row *************************** Level: Note Code: 4569 Message: filter configuration accepted: SET @@GLOBAL.dragnet.log_error_filter_rules= 795
