Hello, Helen I would like to say a few errors in the description of Operator Precedence. Common Language Elements->Expressions->SQL Operators->Operator Precedence 1. Arithmetic Operators. Among the arithmetic operators of places without unary plus (+) and minus (-). They have a higher priority than multiplication and division. Operator Purpose Precedence ---------------------------------- + Unary plus 1 - Unary minus 1 * Multiplication 2 / Division 2 + Addition 3 - Subtraction 3 2. Comparison Operators. All comparison operators have the same priority. Since Firebird 3.0.1. predicate IS has a higher priority than the other comparison operators. The Firebird 2.x predicate IS has the same priority as other comparison operators. Operators Priorities can be found in parse.y // precedence declarations for expression evaluation %left OR %left AND %left NOT %left '=' '<' '>' BETWEEN LIKE CONTAINING STARTING SIMILAR KW_IN NEQ GEQ LEQ NOT_GTR NOT_LSS %left IS %left '+' '-' %left '*' '/' %left UMINUS UPLUS %left CONCATENATE %left COLLATE -- Cheers, Simonov Denis ------------------------------------------------------------------------------ Mobile security can be enabling, not merely restricting. Employees who bring their own devices (BYOD) to work are irked by the imposition of MDM restrictions. Mobile Device Manager Plus allows you to control only the apps on BYO-devices by containerizing them, leaving personal data untouched! https://ad.doubleclick.net/ddm/clk/304595813;131938128;j _______________________________________________ Firebird-docs mailing list Firebird-docs@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/firebird-docs
