Hi,
will be possible to extend firebird installation by SQL stored
procedures that will solve common problems?
It will be like UDF (let say in directory SQL), and every one can
include/use this SQL like fbudf.
Examples of useful:
SP that returns complete metadata for another SP.
SP that set NULL/NOT NULL for column and works on FB2.5 and FB3.
Some examples from our development:
-- Drop Primary Key for given table
CREATE OR ALTER PROCEDURE MASA$DropPrimaryKey(Relation RDB$Relation_Name)
AS
DECLARE VARIABLE cn VARCHAR(500)=NULL;
BEGIN
SELECT TRIM(rc.rdb$constraint_name)
FROM rdb$Relation_Constraints RC LEFT JOIN RDB$Indices I ON
RC.rdb$Index_Name=I.rdb$Index_Name
WHERE I.rdb$Relation_Name=:Relation AND
RC.rdb$Constraint_Type='PRIMARY KEY'
INTO :cn;
IF (cn IS NOT NULL) THEN BEGIN
SQL='ALTER TABLE ' || TRIM(Relation) ||' DROP CONSTRAINT '||cn||';';
EXECUTE STATEMENT SQL;
END
END
