Hi: I have a delphi program where I want to, in English: "update all despatch records for customer X" where XXDESPATCH holds order records , GOORDERS holds order and customer records.
So far I have this code which updates a specific order in table XXDESPATCH:
ADOQuery1.SQL.Clear;
ADOQuery1.SQL.Add('UPDATE xxdespatch  set despstatus= 1, scandate = :NOW where docno = :SELORD and despstatus = 0');
ADOQuery1.Parameters.ParamByName('NOW').Value := Now;
ADOQuery1.Parameters.ParamByName('SELORD').Value := (Edit5.Text);
ADOQuery1.ExecSQL;

Now I need to change edit5.text to a customer code(done!) but have the parameter SELORD pointing at field AccNo in table GOORDERS, joined to XXDESPATCH at docno.

Can anybody help me along here?
Thanks!

UPDATE xxdespatch  
set despstatus= 1, scandate = :NOW 
from xxdespatch A, GOORDERS B
where <<a.commonfield>>=<<b.commonfield>>	 
and docno = :SELORD and despstatus = 0

basically you only need the query ?

update xxdespatch
set despstatus = 1, scandata = :now
where despstatus = 0
  and docno in (select accno from goorders where customercode = :customercode)

this should update all the records for that customer

it's a little easier for us with some data of your tables
