FIX: Running a Query from View Designer Causes Error Message (142201)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 3.0
  • Microsoft Data Access Components 2.5
This article was previously published under Q142201

SYMPTOMS

Using the Run Query option from the View Designer when modifying a previously created view results in a dialog box reporting "CTOD is not a recognized built in function name" for Remote Views and "Function argument value, type, or count is invalid" for Local Views.

This only occurs for views using parameter values where one of the parameter values is compared to a date field and is followed by another selection criteria.

CAUSE

The View Designer wraps the CTOD() function around the parameter value used against the date field, when the view definition is read in.

RESOLUTION

Rearrange the selection criteria so that the date field comparison is the last line.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in version 3.0b.

Steps to Reproduce Problem

Remote View Example

  1. Use the ODBC Administrator to Create a Data Source to the SQL Server Pubs database.
  2. Create a test database, and then create a connection to the SQL Data Source created in step 1.
  3. Create a new remote view, choose the newly created connection, and then select the Sales table. Select all the fields for output.
  4. Create a new parameter (param1) with the datetime data type.
  5. For the selection criteria use the following: 
       sales.ord_date   more than   ?param1
   sales.stor_id    equal       6380
  6. Run the query and type 01/01/94 for the parameter. Two records should be returned.
  7. Save the query, modify it again, and then run it again. The following connectivity error is generated:
    CTOD is not a recognized built in function name"
    View SQL shows that ?param1 has been enclosed within a CTOD() function call. Removing the selection criteria and adding them again in the reverse order prevents the error from occurring.

Local View Example

  1. Open the Vfp\Samples\Data\Testdata.dbc database.
  2. Create a new local view based on the Employee table.
  3. Select all the fields for output.
  4. Create a new parameter (param1) and give it a date data type.
  5. For the selection criteria use the following: 
       employee.birth_date   more than  ?param1
   employee.last_name    like       P%
  6. Run the query and type 01/01/60 for the parameter. Two records should be returned.
  7. Save the query, modify it, and then run it again. The following error is generated:
    Function argument value, type, or count is invalid
    View SQL shows that ?param1 has been enclosed within a CTOD() function call. Removing the selection criteria and adding them again in the reverse order prevents the error from occurring.
