BUG: ESQL: Null Indicators May Not Work with Datetime Columns

Last reviewed: May 5, 1997
Article ID: Q105326
The information in this article applies to:
  • Microsoft Embedded SQL version 4.21 for COBOL
BUG# 9445 (4.21)

SYMPTOMS

In Embedded SQL (ESQL) for COBOL, a static INSERT statement does not insert NULLs into a datetime column, even if the NULL indicator is set. When inserting into a datetime column, the NULL indicator is simply ignored, and the following default datetime value is inserted:

   1/1/1900 12:00AM

However, if the INSERT statement is dynamic, NULLs are inserted correctly using null indicators.

CAUSE

SQL Server Embedded SQL for COBOL incorrectly ignores null indicator when inserting NULLs into a datetime column if the insert is static.

WORKAROUND

Use dynamic SQL statements, or perform updates on the datetime column to change the default datetime values to NULLs using an insert trigger.

STATUS

Microsoft has confirmed this to be a problem in Embedded SQL version 4.21 for COBOL. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
