say i have table_1 with fields a, b & c and i have table_2 with fields a, b & d i want to populate fields a & b of table 2 from records in table 1. in this case, i use: INSERT INTO table_2 (a, b) SELECT table_1.a, table_1.b FROM table_1 but if i do the above, field d of table_2 will always be blank. how do i solve the problem if i want to populate field d of table_2 with a constant value of "hello" ? thanks for your time.
