Update Query

S

Springman

I have two tables [tbl_ACL_data] and [tbl_Update_RESTAT_Client_Code] joined
by [Client_Code] field

I want to populate the tbl_ACL_data.[RESTAT Client Code] field, which is all
null, with the data from the RESTAT_Client_Code1.[RESTAT_Client_Code] field
data.

The Update query returns all blank fields. Please advise me on where I'm
going wrong on this.

UPDATE tbl_ACL_data INNER JOIN tbl_Update_RESTAT_Client_Code1 ON
tbl_ACL_data.Client_Code = tbl_Update_RESTAT_Client_Code1.Client_Code SET
tbl_ACL_data.[RESTAT Client Code] =
tbl_Update_RESTAT_Client_Code1.[RESTAT_Client_Code]
WHERE (((tbl_ACL_data.[RESTAT Client Code]) Is Null Or (tbl_ACL_data.[RESTAT
Client Code])=""));

Are you running the query (Menu: Query: Run) or are you simply switching
the view to datasheet view? If you just switch the view then you will
see what would be updated.

UPDATE tbl_ACL_data INNER JOIN tbl_Update_RESTAT_Client_Code1
ON tbl_ACL_data.Client_Code = tbl_Update_RESTAT_Client_Code1.Client_Code
SET tbl_ACL_data.[RESTAT Client Code] =
tbl_Update_RESTAT_Client_Code1.[RESTAT_Client_Code]
WHERE (((tbl_ACL_data.[RESTAT Client Code]) Is Null Or
(tbl_ACL_data.[RESTAT Client Code])=""));

I've tried both. In both cases the query returns no data.

If you run this query what happens?

SELECT A.ClientCode, A.[RESTAT_CLIENT_CODE]
, B.ClientCode, B.[Restat_Client_Code]
FROM tbl_ACL_data As A INNER JOIN tbl_Update_RESTAT_Client_Code1 as B
ON A.Client_Code = B.Client_Code
WHERE WHERE A.[RESTAT Client Code] Is Null
Or A.[RESTAT Client Code]=""

Do you get any records returned? If not, then there are no records to
update. IF so, what is in the two Restat_Client_Code fields? Do they
have the expected values in them?

If there are records, can you type the correct values into the field? If
not then something is making this query not updateable.

You will have to trouble shoot this.

The Select query returns the appropriate data in all fields.
If I recreate the Update query in a different database with a couple
records, it runs perfectly. Is their a limit on the number of records that
can be updated? I'm updating 1.4M records. I could have just used a make
table query, but the database would grow past 2GB.
