Hello,

I have two tables whose structures are below.

- Table1 - 
table1id int not null auto_increment
data varchar(30)

- Table2 -
table2id int not null auto_increment
table1id int not null
data varchar(30)


These two tables are connected to each other with the "table1id" column. I need to 
delete rows in table1 which have no corresponding "table1id" values in table2 and also 
i need to delete rows in table2 which have no corresponding "table1id" values in 
table1. Any comments?

Thanks.

sql,query
