I need to know where did i do wrong in this sql statement. I try to find solution in previous threads with similar problem but none can solve my problem. so i think maybe my statement is actually wrong.
update table1 b
left join table2 m on b.ICNO=m.ICNO
set b.SalMoveMth = '01'
where
m.Status!='6' and
(DATE_FORMAT(startDateSand,'%m')='10' or DATE_FORMAT(startDateSand,'%m')='11' or
DATE_FORMAT(startDateSand,'%m')='12') and
((select SalMoveMth from table1 where ICNO=table2.ICNO order by SalMoveMthStDt desc limit 1)!='10').
Thank You.
