Hi, this is my first ever post, so go easy on me...
I want to update some fields from table 'cases' to some fields in another table 'casesandcontro ls'. For example I want to add the PSA data from the PSA field in the 'cases' table to the 1PSA field in the 'casesandcontro ls' table, and the data must match up to the corresponding ID. I tried to use an update query to do this but it didn't like how the tables had a primary key, so I removed the primary key from the tables and now it inserts the PSA data into new records and not into the corresponding ID records... any suggestions? My SQL statement is below. Many thanks for your help. Kim
UPDATE [casesandcontrol s] RIGHT JOIN [cases] ON ([casesandcontrol s].[1PSA] = [cases].PSA) AND ([casesandcontrol s].ID = [cases].ID) SET [casesandcontrol s].[1PSA] = [cases].PSA
WHERE ((([casesandcontrol s].[1PSA]) Is Null));

WHERE ((([casesandcontrol s].[1PSA]) Is Null));
Your SQL is trying to JOIN two tables on a field (1PSA) that you are looking for Null in the WHERE clause.
What it is essentially saying is: - Where PSA equals 1PSA set 1PSA to be the same as PSA but only when 1PSA is empty
The following may be of more use - UPDATE [casesandcontrols] RIGHT JOIN [cases] ON ([casesandcontrols].ID = [cases].ID) SET [casesandcontrols].[1PSA] = [cases].PSA
-
WHERE ((([casesandcontrols].[1PSA]) Is Null));

I need to bring the ssn's into UniqueSups (supervisors) from

This is a long post. You can paste the whole message
in the SQL Query Analyzer.
I have a scenario where there are records
with values pointing to wrong records and I need to fix them
using an Update statement.
I have a sample code to reproduce my problem.
To simplify the scenario I am trying to use Order related
tables to explain a little better the tables i have to work with.

So I'm knee deep in this import utility program, and am coming up with all

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.
