ACC2000: Saving Long Expression in SQL View Causes Access to Quit (241194)
The information in this article applies to:
This article was previously published under Q241194 Moderate: Requires basic macro, coding, and interoperability skills.
This article applies only to a Microsoft Access database (.mdb).
SYMPTOMS
In SQL view of a query, if you try to save a long SQL statement, you see one of the following behaviors.
In Windows 95 or 98
You may receive the following error message:
This program has performed an illegal operation and will be shut down.
If the problem persists, contact the program vendor.
When you click Details (on Microsoft Windows Millennium Edition, press ALT+D), you receive the following message: MSACCESS caused an invalid page fault in MSACCESS.EXE at 0167:300ec09b.
NOTE: The actual memory address may vary.
In Windows NT
Access suddenly quits without error.
CAUSE
In SQL view, you tried to save a query that contains a criteria or an expression that has more than 511 characters.
RESOLUTION
To resolve this problem, obtain Microsoft Office 2000 Service Release 1/1a (SR-1/SR-1a).
To obtain SR-1/SR-1a, click the article number below to view the article in the Microsoft Knowledge Base:

To work around this problem, do not try to edit a criteria or an expression of an existing query in SQL view if the criteria or expression has more than 511 characters.
If you do want to create a query with a criteria or an expression that has more than 511 characters, use the CreateQueryDef method in a Visual Basic for Applications procedure. The following example illustrates how to do this. CAUTION: If you follow the steps in this example, you modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and follow these steps on a copy of the database. - Open the sample database Northwind.mdb.
- Click Modules under Objects, and then click New.
- In the new module, type the following code:
Option Compare Database
Sub CreateLongQuery()
Dim db1 As DAO.Database
Dim qdfNew As DAO.QueryDef
Set db1 = CurrentDb
With db1
Set qdfNew = .CreateQueryDef("LongExpQuery", _
"SELECT Employees.EmployeeID, [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] & [Employees]![Lastname] & " _
& "[Employees]![Lastname] AS Expr1 FROM Employees;")
.Close
End With
Application.RefreshDatabaseWindow
End Sub
- In the Immediate window, type the following line, and then press ENTER:
A new query called LongExpQuery appears in Access.
To make changes that require a criteria or an expression that has more than 511 characters, create a new query with the changes that you need by once again using the CreateLongQuery procedure.
You can run the query that you created in this example, but you cannot edit its expression in the query design grid if it has more than 511 characters.
