Subj:   UPDATE, SET, & Subquery
 
From:   dnelson

Hello,

I can find reasons why the following should work(through general SQL documentation) and no explanation why is does not.

Nevertheless, a syntax error is returned through SQL Assistant.

The actual table / column names have been stripped out for simplicity. Ultimately, the goal is to update a column in a summary table with the COUNT(1) from a table of details. Does Teradata not support suqueries outside the WHERE/FROM clauses?

Any information would be appreciated. Thanks.


Sincerely,

Dan


     UPDATE SUMMARY_TABLE
     SET
     TOTAL_COLUMN =
     (SELECT COUNT(1)
     FROM TABLE_OF_MISMATCHES)
