Moderate: Requires basic macro, coding, and interoperability skills.
SYMPTOMS
When you run an update query from Microsoft Access to copy the contents of one SQL Server Memo field into another SQL Server Memo field, the data in the new field will be truncated at 255 characters.
CAUSE
This behavior will occur when you add criteria to one of the SQL Server fields, that field is part of an index, and you are using any of the following 32-bit ODBC drivers:
Driver Version Source ------------ --------- --------------------------------------------- SQLSRV32.DLL 2.50.0126 Microsoft Access 7.0 2.65.0201 ODBC Desktop Driver Pack 3.0 (Q139487) 2.65.0213 Microsoft Access 97 (Q159674) 2.65.0240 SQL Server 6.5
To obtain the latest drivers, install the Microsoft Data Access Components (MDAC) 2.0 from the following Microsoft Web site:
RESOLUTION
Remove the criteria you have set on the indexed field.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Access 97.
MORE INFORMATION
Steps to Reproduce Problem
Create a table called TEST in MS SQL Server 6.5 with the following structure:
Key ColumnName Datatype Size Nulls Default ---- ----------- -------- ---- ----- ------- Y EmployeeID int 4 LastName char 25 Notes text 16 Y Notes2 text 16 Y
- Open the sample database Northwind.mdb.
- Create a link to the Test table you created in step 1.
- Create an append query that appends the EmployeeID and Notes field from the Employees table to the EmployeeID and Notes field in the Test table. This will provide sample data for the SQL table.
Create an update query based on the dbo_test table in Microsoft Access by typing the following syntax in the SQL View window:
UPDATE dbo_Test SET dbo_Test.Notes2 = [dbo_test]![notes] WHERE (((dbo_Test.EmployeeID)=2));
- Run the query.
- Open the dbo_Test table to view the results.
Note that the query updates the Notes2 Memo field with the data from the Notes Memo field. However, the data in the Notes2 field is truncated at 255 characters.
