ACC: Type Mismatch Specifying Criteria on Count in Query
ID: Q151867
|
The information in this article applies to:
-
Microsoft Access versions 2.0, 7.0, 97
SYMPTOMS
Novice: Requires knowledge of the user interface on single-user computers.
When you specify Text criteria for a Text field with Count in the Total
row of a totals query, you may receive the following error message:
Type Mismatch
CAUSE
The Text criteria is being compared to the result of the Count, which is
numeric.
RESOLUTION
You can use one of the following two methods to work around this behavior.
These two methods assume that the criteria is meant to limit the records
before the Count is performed by the query.
Method 1
You can add the field to the query a second time and use Where on the Total
row. The following example uses the sample database Northwind.mdb (or
NWIND.MDB in version 2.0) to demonstrate adding a field to a totals query
twice.
- Open the sample database Northwind.mdb (NWIND.MDB in Microsoft Access
version 2.0) and create a new query based on the Orders table.
- Click the Totals button on the toolbar.
- Add the field ShipName to the query and select Count on the Total
row.
- Add the field ShipName to the query again. Select Where on the
Total row. On the Criteria row type "Quick-Stop". Run the query and
note that it returns the correct count.
NOTE: In Microsoft Access 2.0, there is a space in the Ship Name field.
Method 2
Use two queries. The following example demonstrates how to build a totals
query based on a select query with a Text criteria:
- Open the sample database Northwind.mdb (or NWIND.MDB in version 2.0) and
create a new query based on the Orders Table.
- Drag the ShipName field into the first column of the QBE grid. Type
"Quick-Stop" in the Criteria row. Save the query as Ship Name 1.
- Create another new query based on the Ship Name 1 query. Drag the
ShipName field to the QBE grid in the first column. Click the
Totals button on the toolbar, and then select Count in the Total row.
- Run the query and note that it returns the correct count.
MORE INFORMATION
Steps to Reproduce Behavior
- Open the sample database Northwind.mdb (or NWIND.MDB in version 2.0).
Create a new query based on the Orders Table.
- Drag the ShipName field to the first column of the QBE grid.
- Type "Quick-Stop" in the Criteria row.
- Click the Totals button on the toolbar, and then select Count in the
Total row of the QBE grid.
- Run the query. Note that you receive the "Type Mismatch" error.
