SYMPTOMS
When you pass an ODBC canonical date literal as a parameter to a SQL Server stored procedure using the Microsoft SQL Server ODBC driver, a syntax error may be reported:

[Microsoft][ODBC SQL Server Driver]Invalid time format



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next MDAC service pack that contains this hotfix.

The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:

  Date       Version   Size     File name    Platform -  08/01/2000 3.70.8.92 524,560  SQLSRV32.DLL   x86 08/01/2000 3.70.8.92 24,848  ODBCBCP.DLL    x86



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
The ODBC canonical date escape sequence provides a generic way to pass a literal date to an ODBC driver. Because there is a single canonical date format, you can pass literal dates to any ODBC driver and be sure that the proper date will be stored in the database.

The exact format is as follows: {d 'yyyy-mm-dd'} Here is a simple example of using an ODBC canonical date in a SQL insert statement: insert into table1 (f1) values ({d '1999-12-31'})

Steps to Reproduce Behavior
To reproduce the problem, use the ODBC Test utility (which is provided with the MDAC SDK) as follows:   In the input window, paste the following statement, and then press CTRL+E to execute it: create procedure tmpDateTest( @d datetime ) as select @d This calls the SQLExecDirect ODBC function and creates a stored procedure with datetime as an input parameter.   Paste the following statement (replacing the previous one) and press CTRL+E: {call tmpDateTest({d '1999-12-31'} This calls the stored procedure with a canonical date as an input parameter. The error is displayed in the output window.
