Re: Table locking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have an orders with one main record in table1 ( client, date, e.t.c. ) and
detail description in table2  ( all materials with quant, price, e.t.c. )
and I save data  in table1 for positions (range of id - autoinc field of
records in table2) for detailed data of order . And I don't want someone
else to insert data in table2, because will be a problem with orders.
Now I insert data first in table2 and then insert main record in table1 with
the range of id's of detail order data.

Could be some solution for this ?

Thanks in advance.
