Limits the maximum number of iterations a recursive common table expression can make.

Allowed values

Integer

Default

100

Scope

Can be set for an individual connection or for the PUBLIC group. Takes effect immediately. DBA authority required to set this option for the PUBLIC group.

Remarks

Computation of a recursive common table expression aborts and an error is generated if the computation fails to complete within the specified number of iterations. Recursive subqueries often increase geometrically in the amount of resources required for each additional iteration. Set this option to limit the amount of time and resources that will be consumed before infinite recursion is detected, yet permit your recursive common table expressions to work as intended.

Setting this option to 0 disables recursive common table expressions.
