Another thought, the constraint you're creating requires a primary key
constraint on table2. If it's not there it will be built for you. Perhaps
it's building the primary key constraint on table 2?

Subject: sql - Drop and Add constraints



Sorry about not changing the subject on the last reply.

We have a process that drops the constraints on tables (physical files),
clears them with a CLRPFM, and then rebuilds the constraints. At first this
process took 20 minutes. Now it takes 2 1/2 hours. My question is why? or
how is this possible?

Here is a small sample:

RUNSQLSTM  SRCFILE(SourceLib/SourceFile) SRCMBR(Member1) +
             NAMING(*SQL) DFTRDBCOL(DataLib)

CLRPFM     FILE(Table1)
.
.

RUNSQLSTM  SRCFILE(SourceLib/SourceFile) SRCMBR(Member2) +
             NAMING(*SQL) DFTRDBCOL(DataLib)

Here is some of the sql source from each member:

Member1:
ALTER TABLE Table1
       DROP CONSTRAINT R_1848;

Member2:
ALTER TABLE Table1
       ADD CONSTRAINT R_1848
              FOREIGN KEY (key1, key2)
                             REFERENCES Table2
                             ON DELETE CASCADE
                             ON UPDATE RESTRICT;

Yes.

Is this the correct forum for SQL questions?
