Forum Post: RE: How to update a column in one table by getting values from a column in another table when subquery returns "more than one rows" error.

Hi Arijit, thanks for your suggestion, it actually worked. I have used the following statement: MERGE INTO Table_1 a USING (SELECT P_FID, P_Value FROM Table_2) b ON (a.N_FID = b.P_FID) WHEN MATCHED THEN UPDATE SET a.N_Value = b.P_Value WHERE a.N_Value = '21000'
