[comp.databases] SQL script corrections needed

dan@hrc.UUCP (Dan Troxel) (05/31/89)

What I need to do is get data from three tables.
billing is the main table and has the bill info
acctrec is the info table on the client
hwstat has the name of the individual for this entry of the bill

At times, hwstat will not have a record found, but I still want the
rest of the info printed. The following does not work, so what do I do
to correct the situation?

	billing.bkey, billing.id_num, billing.writnum, billing.reference,
	billing.units, billing.bill_date, billing.description, billing.unit_cost,

	billing.bill_num, billing.bill_make, billing.bill_make_date,
	billing.bill_pay_date, acctrec.company,hwstat.writers_name

from billing, acctrec, hwstat

where 
	billing.id_num between 100 and 150
and
	acctrec.id_num = billing.id_num
and
	billing.bill_date <= 05/31/89
and
	hwstat.client = billing.id_num
and
	hwstat.writing_num = billing.writnum

order by
	billing.id_num,billing.bill_num,billing.bill_date/
