2017-12-23 select year, batch from tb1 left join tb2 on tb1. key = tb2.foreignkey There is a tutorial on how to write MySQL queries at tutorialspoint [Edit] If you have many columns that you want to match on between the tables then just add those columns to the ON clause. Eg left join tb2 on tb1.key = tb2.foreignkey and tb1.col2 = tb2.col2 and tb1.col3 = tb2.col3 etc 2013-11-27 2010-07-21 2017-04-07 2018-02-10 Given table TB1 and TB2, I want to first find the common records of TB1 and TB2, and then delete those common records in TB1. Here's the SQL statement to find the distinct common select distinct TB1.* from TB1 INNER JOIN TB2 ON TB1.RMA = TB2.RMA AND TB1.Parts = TB2.Parts AND TB1.PPID = TB2.PPID; If I want to delete the common records in TB1 SELECT TB1.*, TB2.D1, TB2.D2 FROM TB1 INNER JOIN TB2 ON TB1.C1 = TB2.C1 AND TB1.C2 = TB2.C2 AND TB1.Cn = TB2.Cn . Join operations. A join-condition (or USING clause) specifies pairings of T1 and T2, where T1 and T2 are the left and right operand tables of the JOIN operator of the join-condition (or USING clause).
