To enable and disable all triggers of a database i do two procedure : Enabling all database trigger:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
create procedure SP_ENABLE_ALL_TRIGGER as begin /* Procedure Text */ update RDB$TRIGGERS set RDB$TRIGGER_INACTIVE=0 where RDB$TRIGGER_NAME in( select A.RDB$TRIGGER_NAME from RDB$TRIGGERS A left join RDB$CHECK_CONSTRAINTS B ON B.RDB$TRIGGER_NAME = A.RDB$TRIGGER_NAME where ((A.RDB$SYSTEM_FLAG = 0) or (A.RDB$SYSTEM_FLAG is null)) and (b.rdb$trigger_name is null) AND (NOT(A.RDB$TRIGGER_NAME LIKE 'RDB$%')) ); suspend; end |
Disabling all database trigger:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
create procedure SP_DISABLE_ALL_TRIGGER as begin update RDB$TRIGGERS set RDB$TRIGGER_INACTIVE=1 where RDB$TRIGGER_NAME in( select A.RDB$TRIGGER_NAME from RDB$TRIGGERS A left join RDB$CHECK_CONSTRAINTS B ON B.RDB$TRIGGER_NAME = A.RDB$TRIGGER_NAME where ((A.RDB$SYSTEM_FLAG = 0) or (A.RDB$SYSTEM_FLAG is null)) and (b.rdb$trigger_name is null) AND (NOT(A.RDB$TRIGGER_NAME LIKE 'RDB$%')) ); suspend; end |
With that simple peace of code you can retrive the full list of all “FK” Foreign Key of an Interbase or Firebird DB.

Hi, I think might be helpful, today for a customer i do the Haversine formulas for Firebird Sql as a stored procedure. This formula allow you to calculate the distance in meter between two WGS84 datum points(degree points of Earth). You can call the procedure like this:
|
1 |
SELECT * FROM HAVERSINE_GENERIC(1, 45,474081, 9,179348, 45,456091, 9) |
The result wil be aprox 14Km, the…
