hello . i want to run a query using the delete and join statement

I am having issues deleting items from a table.

I have two tables.

Table A and Table B contains all the record. They should both have same
number of records.

Table A fields.
inv_num
inv_date
companyid
order_num
rel_num
trad_partner
report_name
inv_order_num

Table B fields
Counter
Data Type
DATE
TIME
From_name
Receiver name
Receiver ID
order_num
inv_num
ENV_CTRL_
GROUP_CTRL_
Transaction_

I am trying to delete records from table B with no match in table A. where
invoice number and company iD is Null.

Currently, I have 30 records in table A and 40 records in table B.

I want table A and B to have 30 records.
Therefore, I want to delete records in table B that does not exist in table
A.

I tried this but it did not work. Nothing is being deleted. i know that i
have some rcords in table B not in table A. What am I doing wrong. Please
help!!!

DELETE DISTINCTROW [tableA].*, tableB. inv_num
FROM tableA LEFT JOIN tableB ON ([tableA].inv_num= tableB.inv_num) AND
([tableA]. order_num= tableB. order_num) AND
([tableA].companyid=tableB.From_name)
WHERE (((tableB. inv_num) Is Null));
