Question

I have two tables.

tbl1

id             int(11)      NOT NULL

userName       varchar(45)  NOT NULL

positionName   varchar(20)  NULL

positionId     int(11)      NULL

tmpTbl1

id             int(11)      NOT NULL

userName       varchar(45)  NOT NULL

positionName   varchar(20)  NULL

positionId     int(11)      NULL

In tbl1, only id and userName columns have data. for tmpTbl1, all columns have data.

I want to copy positionName and positionId of tmpTbl1 to tbl1.

Both tables have same structures and id and userName columns data are same too. Just want to update the left two columns data into tbl1.

Thanks ahead.

Tested quickly – but I think this will work for you

UPDATE tbl1 t1, tmpTbl1 t2 
SET t1.positionName=t2.positionName, t1.positionId=t2.positionId 
WHERE t1.id=t2.id AND t1.userName=t2.userName;
