How to UPDATE one column using another column in another table? SQL Error: ORA-00933: SQL command not properly ended

Question

I have tried everything I can think of but couldn\'t solve this SQL error:

SQL Error: ORA-00933: SQL command not properly ended

Answer 1

UPDATE SALES_DATA_FAMILY_2007 A 
SET A.POG_ID= (select B.POG_ID 
                 FROM POG_HIERARCHY B  
                WHERE A.FAMILY_ID=B.FAMILY) ;

This will work if and only if there's at most one corresponding row in POD_HIERARCHY for a given FAMILY. If there's more than one row in POD_HIERARCHY, then you need to determine which row from POD_HIERARCHY you wish to use the value from.
