Hi,
Thanks to many who clued me on on using "arrow keys" to
traverse history. I just installed readline and 7.1 .. seems that
mysql has its own readline.
I want to use this referential integrity etc. that I've never used in
mysql ... so I tried many things and looked here and there ... My
example below produces this error:
> CreateTrigger: function check_primary_key() does not exist
Here is what I was trying to create:
DROP TABLE company_profile;
CREATE TABLE company_profile (
employer_id int4,
leadership text,
company_description text,
key_financial_statictics varchar (255),
company_name varchar (255),
url varchar (255),
sec_fillings_url varchar (255),
mission text,
employees int4,
type varchar (50),
growth_rate varchar (50),
culture text,
year int4,
PRIMARY KEY (employer_id)
);
CREATE TRIGGER employer_id_exists
BEFORE INSERT OR UPDATE ON company_profile FOR EACH
ROW
EXECUTE PROCEDURE check_primary_key('employer_id',
'employer_profile', 'employer_id');
__end example
I just copied the above TRIGGER .... but it doesn't work for me.
Thanks,
Peter
