How to Save Records only if no records exist in another table?

G

gg

I have searched through the forum for examples on saving records only if a
certain condition exists but can't seem to figure out where to add the "if"
statement in my code below. I have created a query to test if a contract#
exists or not. If it does NOT exist in the Billing table, then go ahead and
SAVE any field changes to Effective_contract_detail table and to the audit
trail, Effective_contract_detail_log table. If the contract# exists in
Billing table, then DO NOT SAVE to Effective_Contract_detail table (because
no changes are allowed) but do SAVE to the Effective_contract_detail_log
table. Help, please. Thank you!!

As currently written, your code should *add* a record (not save changes) to
Effective_contract_detail_log if any changes have been made to the specified
fields. If you also want to add a record when no changes have been made to
those fields, then simply remove the very,very long "If Me!product_no <>
preProduct_no Or ..." statement and you will always add a record whenever
the piece of code runs.

If there are conditions under which you do *NOT* want to add a record to the
Log, then I don't think we have enough info to answer the question.

Thanks, but how do I save the contract record (not the log record) only if
the contract# does NOT reside in another table (I have the fields in the
query)? I have added the "if" statement:
If IsNull(Dlookup("contract_no", "qryBill_EffContract_forDelete",
"[contract_no] = " & Me!contract_no))
DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70
Else
DoCmd.CancelEvent
Me.Requery
End If

Thanks, George!

That doesn't work for you? Oh, maybe it's the missing "Then" at the end?

It was a typo in my post. Thanks!

I still am missing some line of code to get this logic to work. It is still
either saving to both tables or not at all.
