Hello, This is my first post here. I tried to search the archive but did not find anything related. We build application and would like disable foreign keys in a procedure. Something like: CREATE PROCEDURE crmkartaaktivita_drop_cons() BEGIN -- hlavička procedury DECLARE v_proc VARCHAR(250); SET v_proc = 'crmkartaaktivita_drop_cons'; -- drop ALTER TABLE crmkartastitek DROP CONSTRAINT crmkartastitek_crmkartaaktivita_FK; ALTER TABLE crmkartastitekm DROP CONSTRAINT crmkartastitekm_crmkartaakitvita_FK; END; / I'm getting "Statement 'ALTER_TABLE' is not a valid flow control statement". Is there any way around please? Our algorithm should like this: 1. disable/drop foreign keys. 2. load data. 3. enable/create constraints. Thanks, Radovan -- Radovan Biciste Czech Republic
