Access query via VBA problem with quotes

It is not so simple to debug so complex query. Assign query to variable. In this case you can debug it without problems.

SQL = "INSERT INTO TPLPaymentDetailT ( PaymentID, PaymentType, Amount, StatementNo ) "
SQL = SQL & "SELECT " & co2id & " AS PaymentID, 'Payment Based on Audit' AS PaymentType, IIf([partiallypaid]=False, "
.....
....

debug.print SQL

Select allOpen in new window

You will see errors.

Okay, I did that. Now the whole SQL= section turned red, and I can't debug it because the code won't run - syntax error.

Any ideas? My guess is that it may be the two single quotes on line 4, but I don't know how else to write that dlookup.

Place result here.

Can't do debug.print sql, because I can't get that subroutine running due to syntax error.

sql =  "INSERT INTO TPLPaymentDetailT ( PaymentID, PaymentType, Amount, StatementNo ) " & _
    "SELECT " & co2id & " AS PaymentID, 'Payment Based on Audit' AS PaymentType, IIf([partiallypaid]=False, " & _
    "[AmountPaid],[amountpaid]- DLookUp('amount','tplpaymentdetailt','statementno=' & [statementno] & _
    "' AND type = 'Pay Based on Percentage'')) AS Amount, TPLTotalAmountPaidPerCompanyQ.promptstatement AS StatementNo " & _
    "FROM TPLStatementT RIGHT JOIN TPLTotalAmountPaidPerCompanyQ ON TPLStatementT.StatementNo = " & _
    "TPLTotalAmountPaidPerCompanyQ.PromptStatement " & _
    "WHERE (((TPLTotalAmountPaidPerCompanyQ.Company)=2));"

Select allOpen in new window

Divide string as I've suggested:
SQL = "first line"
SQL = SQL & "Second line"
You will be able to find line with error. Divide this line to small parts and find problem part.
If you need quote in string, you can use chr(34) or double "". For example:

SQL = SQL & "- DLookUp(" & Chr(34) & "amount" & Chr(34) & ",""tplpaymentdetailt"",""statementno="" & [statementno]"

Select allOpen in new window

First, rather then get the value of the dlookup in the statement, fetch the value first into a variable, then use the variable in the SQL statement.

That makes it easier.

Second, why are you using a Dlookup() in a SQL statement?  The domain functions represent SQL statements and are meant to be used in places where SQL is not.  Here you can.

 The problem with them in this context is that the query parser cannot optimize them and you will always get poor performance.

Jim.

sql =  "INSERT INTO TPLPaymentDetailT ( PaymentID, PaymentType, Amount, StatementNo ) " & _
    "SELECT " & co2id & " AS PaymentID, 'Payment Based on Audit' AS PaymentType, IIf([partiallypaid]=False, " & _
    "[AmountPaid],[amountpaid]-" & DLookUp('amount','tplpaymentdetailt','statementno=' & [statementno] & _
    "' AND type = 'Pay Based on Percentage'')) & " AS Amount, TPLTotalAmountPaidPerCompanyQ.promptstatement AS StatementNo " & _
    "FROM TPLStatementT RIGHT JOIN TPLTotalAmountPaidPerCompanyQ ON TPLStatementT.StatementNo = " & _
    "TPLTotalAmountPaidPerCompanyQ.PromptStatement " & _
    "WHERE (((TPLTotalAmountPaidPerCompanyQ.Company)=2));"

@Jim:
I'm using DLookup in SQL, because I don't know how to do that particular join.

What I need: if a certain field (PartiallyPaid) is flagged, then join with another table and pick up a matching value with criteria with another field. No clue how to do that.

I can't fetch the variable and put it into the sql, because this sql inserts multiple rows, and the target value is different for each row.

@als315: I will try using Chr(34)

@Jim: your code gives the same error (and the whole block of code turns red)

@als315: replacing the quotes for the dlookup with Chr(34)  did not help. This is my new code:

sql =  "INSERT INTO TPLPaymentDetailT ( PaymentID, PaymentType, Amount, StatementNo ) " & _
    "SELECT " & co2id & " AS PaymentID, 'Payment Based on Audit' AS PaymentType, IIf([partiallypaid]=False, " & _
    "[AmountPaid],[amountpaid]- & DLookUp(" & chr(34) & "amount" & chr(34) & "," & chr(34) & "tplpaymentdetailt" & chr(34) & "," & chr(34) & "statementno=' & [statementno] & _
    "' AND type = 'Pay Based on Percentage'" & chr(34) & ")) & " AS Amount, TPLTotalAmountPaidPerCompanyQ.promptstatement AS StatementNo " & _
    "FROM TPLStatementT RIGHT JOIN TPLTotalAmountPaidPerCompanyQ ON TPLStatementT.StatementNo = " & _
    "TPLTotalAmountPaidPerCompanyQ.PromptStatement " & _
    "WHERE (((TPLTotalAmountPaidPerCompanyQ.Company)=2));"

Select allOpen in new window

alas315: That did it! I don't totally understand the double quotes and all, but if it works...
Jim: thanks for your help as well.

Just a thought, what is the relationship between tplStatementT and tplPaymentDetailT?  is this a 1-to-1, 1-to-0 or 1 (may not be a detail record for each statement), or 1-to-many?

If it is a 1-to-1 or 1-to-0 or 1, then you could use an outer join to connect those tables, but if it is 1-to-many relationship, you need to replace the DLOOKUP in your query with a DSUM(), since the DLOOKUP will only return the 1st value from that table, not all of the values.

1 to many. However, I'd only want the join when a certain field in tplStatementT is flagged. Is that possible? If it's not, I don't want to end up with all those extra rows from tplPaymentDetailT.

You could do a join to a sub-query which would group by the join field and sum across the Amount field in that table.  This would be quicker than using DLOOKUP or DSUM.  But you definately should consider using the DSUM() function rather than DLOOKUP(), otherwise, you will only subtract a single value, rather than the sum of all payments.

There will only ever be one record in the tplPaymentDetailT with a type of "Pay Based on Percentage" for any particular statement record. That's why I used Dlookup.

I could try a subquery, but for now I think I'll leave it as it is. After all, it works, and it's not too slow because the query updates an average of 1-3 records. But I'll keep it in mind.
