There are 2 tables A and B with A being the parent of B.
Table A
(
Col1 varchar(5) Not Null
)
Table B
(
B_PK varchar(5) Not Null ,
B1 varchar(5) ,
B2 varchar(5)
)
Basically what we want to do was if any A.Col1 is deleted and there
are matching B1 or B2, set them to null for those records.
I know if we use 'on delete' with rules other than 'SET NULL', it
would be fine. But what is wrong with setting any related FK values to
null when its corresponding PK is deleted??
D:\DBA\LDS>db2 create table A (Col1 varchar(5) not null)
DB20000I The SQL command completed successfully.
D:\DBA\LDS>db2 alter table A add primary key (col1)
DB20000I The SQL command completed successfully.
D:\DBA\LDS>db2 create table B (B_PK varchar(5) not null, B1
varchar(5), B2 varchar(5))
DB20000I The SQL command completed successfully.
D:\DBA\LDS>db2 alter table B add primary key (B_PK)
DB20000I The SQL command completed successfully.
D:\DBA\LDS>db2 alter table B add foreign key (B1) references A on
delete set null
DB20000I The SQL command completed successfully.
D:\DBA\LDS>db2 alter table B add foreign key (B2) references A on
delete set null
DB21034E The command was processed as an SQL statement because it was
not a
valid Command Line Processor command. During SQL processing it
returned:
SQL0632N FOREIGN KEY "B2..." is not valid because the table cannot be
defined
as a dependent of table "LDSDEV.A" because of delete rule restrictions
(reason
code = "3"). SQLSTATE=42915

What product and what version? DB2 for Linux/Unix/Windows added support
for what you're trying to do in Fixpack 3 of Version 8.1
Regards,
Miro
We are running DB2 v8.1.1.0, fixpak 0 on AIX v5. I'll see if we could
put FixPak3 on the server, which has Websphere stuffs on it ...
Thanks.
DB21085I Instance "ldsdbdev" uses "32" bits and DB2 code release
"SQL08010"
with level identifier "01010106".
Informational tokens are "DB2 v8.1.1.0", "s021023", "", and FixPak
"0".
Product is installed at "/usr/opt/db2_08_01".

Base code with no fixpaks is very buggy. Fixpak 4 is expected soon. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I have two tables that are related by keys. For instance,
Table employee {
last_name char(40) not null,
first_name char(40) not null,
department_name char(40) not null,
age int not null,
...
}
Employee table has a primary key (combination of last_name and first_name).

Sorry to bother you guys but I have another questions related to DataSets.
I'm almost there now, so I dont expect to bug you much more ( Hopefully ).
I have Master / Details tables with cascading relationships between them.
When I Update the master using the DataAdapter we get a new ID for the new
master row and all the child row foreign keys are updated to the newly
aquired ID.

We are working on a gridview inside the gridview (parent-child) scenario.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
