var ErrVisibilityMixedWithOtherChanges = errors.New("the ALTER operation contains a change to index visibility mixed with table-rebuilding operations. This creates semantic issues for experiments. Please split the ALTER statement into separate statements for changing the invisible index and other operations")
ErrVisibilityMixedWithOtherChanges is returned when index visibility changes are mixed with table-rebuilding operations
Functions ¶
func AlterContainsIndexVisibility ¶
func AlterContainsIndexVisibility(stmt *statement.AbstractStatement) error
AlterContainsIndexVisibility checks to see if there are any clauses of an ALTER to change index visibility. Allows index visibility changes when mixed with other metadata-only operations, but blocks them when mixed with table-rebuilding operations to avoid semantic issues.
