Hi all,
I want to get the difference between 2 tables.
table_1:
column_1
A
B
C
D
table_2:
column_2
B
C
What is the sql select syntax to get as result A,D or B,C?
Thanx for your help.
Regards,
Bernd

Before
mysql select table1.* from table1
LEFT JOIN table2 ON table1.column_1=table2.column_2
where table2.column_2 is NULL;
try this to select row of table 2 not in table 1, i think.
