I'm trying to copy information from one field to another in two different tables in a MySQL DB. The fields have the same names and the table need to be matched on fields that have the same names. The statement I've been trying is:
INSERT INTO table1 (fld_A) SELECT table2.fld_A FROM table2 WHERE table1.fld_B = table2.fld_B
The error shows that it is not picking up the table1 in the WHERE clause.
