In Postgres 8 I tried commad
DELETE FROM customer WHERE id=123
but got an error
ERROR: update or delete on "customer" violates foreign key constraint
"invoice_customer_fkey" on "invoice"'
How to determine the primary key of invoice table which causes this error
in generic way ?
Why Postgres does not report primary key value in error message ?
I it is not possible to add more information to error I need function which
takes 3 arguments:
table name ('customer')
field name ('id')
field value (123)
and returns the name of the table and primary key value which blocks
record deletion.
I looked to the ODBC log, but this does'nt contain more information
about error !?
