Query Help, Showing Records Not In table
Experts, I have been having troubles with these queries. I dont know what I am doing wrong. It is quite simple but something seems to not be working.
If you look at the pared down db.
Open the query
It shows 2 records that are NOT IN tblLetterOfCredit on LCNo and L/C Ref
However, both of those records are in tblLetterOfCredit.
The only difference between them is a "-" dash but the function (StrippedChar) is suppose to remove the "-" and compare but the query still shows those 2 records as NOT IN tblLetterOfCredit.
What is happening? These queries are about to drive me nuts because I think I understand what is happening but then what I learned goes out the window (as in this example).
Please open the pared down db. There is probably a simple answer to this that I cant see.

It won't display in design view because of the functions that you need to make the comparison you want (not exactly an error).
Have you tried going directly from SQL to datasheet view?
--->> What makes it a RIGHT or LEFT qry?
Right and Left specify from which table ALL records are to be pulled.
eg in this JOIN, all records are pulled from table1 and only matching records from table2:
Conversely, in this JOIN, all records are pulled from table2 and only matching records from table1:
Without design view as a visual aid, the RIGHT or LEFT simply means which side of the JOIN a table appears on in SQL view.

Yes, I dont get the error.
Shouldnt there be a line drawn between the 2 tables though? It says RIGHT join so I am thinking there should be a line showing the relationship.
The bold and underlined is not needed, correct? Also, if I delete simply the column I get errors when run...I have to delete the bolded below within the SQL.
SELECT [Import-DnB].[L/C Ref], tblLetterOfCredit.LCNo, StrippedChar([L/C Ref]) AS [LC Ref DNB], StrippedChar([L/C Ref]) AS [LCRef_Import-Dnb_Me], StrippedChar([LCNo] & "") AS LCNo_tblLetterOfCredit_Me
FROM tblLetterOfCredit RIGHT JOIN [Import-DnB] ON StrippedChar(tblLetterOfCr
WHERE tblLetterOfCredit.LCNo IS NULL
This is the final (I removed those columns from above):
I really appreciate your explanations. It seems like I would be best served using WHERE condition as Is Null in the testing criteria.

Did removing the underlined code work in SQL and datasheet view?
if so you are good to go.
The lack of a line in design view is not a problem. This query as well as other types of queries simply will not render in design view even though they are syntactically fine. When that happens, you just need to stick to SQL and datasheet view (and not try to work in design view or worry about access's failed attempts at rendering it in design view)

Thank you! Good night....:)

What makes it a RIGHT or LEFT qry? In the query code above, there is not line drawn between the two tables but I do see it is a RIGHT join. Maybe it doesnt show the line because of the error?
thank you
