sql server 2008 - MS SQL Insert from multiple rows -

-

i´m trying insert values database several tables:

insert dbo.table1 (id, idtable2, idcounter) select s.id o.idtable2 o.idcounter dbo.table3 o, dbo.table2 s

but above code leads situation duplicate values values table 3, want 1 value table3 per value table 2. (the tables don´t have relationship info)

thanks in advance.

edit:

thanks everyone. managed solve adding reference id table2 , using inner join.

you forgot clause joining tables table2 , table3, building cartesian product. there must linking tables; otherwise makes no sense combine them do.

my advice: stay away old join syntax list tables comma-separated. use up-to-date join syntax (inner join on etc.) instead.

having said this, don't see how select make sense anyhow. id become id of table2 , idtable2 become id of table2, too?
