Bug #: 1833 (WebData QFE)



Microsoft distributes Microsoft SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by the hotfix package
 * The prerequisites for installing the hotfix package
 * Whether you must restart the computer after you install the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
When you perform a bulk copy operation by using the DB-Library API in Microsoft SQL Server 2000 Service Pack 4 (SP4), incorrect data is inserted unexpectedly.

Note This problem does not occur in Microsoft SQL Server 2000 Service Pack 3 (SP3).



CAUSE
This problem occurs because of a design change in SQL Server 2000 SP4. When you perform a bulk copy operation by using the DB-Library API, the bcp_init function performs the necessary initializations. In SQL Server 2000 SP3, the bcp_init function uses the clustered index that is created on the following columns in the syscolumns table to return the data:
 * The id column
 * The colid column
 * The number column

Therefore, the data is returned in the order of the colid column in the syscolumns table.

In SQL Server 2000 SP4, the bcp_init function uses the nonclustered index that is created on the following columns in the syscolumns table to return the data:
 * The id column
 * The name column
 * The number column

Therefore, the data is returned in the order of the name column in the syscolumns table.
