Bug #: 50001061 (SQL Hotfix)



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
Consider the following scenario. You create a foreign key between table A and table B in Microsoft SQL Server 2000. You run the CREATE INDEX statement for table A. In this scenario, the following symptoms occur:  The foreign key that was created between the two tables does not work. You can drop the primary key constraint on table A, even if the primary key is referenced by the foreign key constraint on table B. If you run the DBCC CHECKCATALOG statement against this database, you receive the following error message:

Server: Msg 2513, Level 16, State 14, Line 1

Table error: Object ID  (object ' ') does not match between 'SYSREFERENCES' and 'SYSINDEXES'.

DBCC results for 'current database'.

DBCC execution completed. If DBCC printed error messages, contact your system administrator.



This problem occurs if the following conditions are true:
 * A nonclustered index or a statistic exists on table A.
 * A nonclustered primary key is created on table A. The newly created primary key has a larger value of the indid column in the sysindexes system table than the value of the indid column of the index or the statistic that is mentioned in the first item.
 * A foreign key exists on table B and references the primary key of table A.
 * The nonclustered index or the statistic that is mentioned in the first item is dropped.
 * You run the CREATE INDEX statement to create an index on table A.
 * In the CREATE INDEX statement, you set the DROP_EXISTING option to ON to drop the existing primary key.

Steps to reproduce the problem
 Start SQL Query Analyzer, and then create a new query.</li>  Run the following statements. create table x( a int not null, b int not null, c int not null) go create clustered index xcidx on x(a) go create statistics xstat on x(c) go alter table x add constraint xpk primary key nonclustered (b) go create table y (b int not null, c int not null) go alter table y add constraint yfk foreign key (b) references x(b) go select * from sysindexes where id = object_id('x') select * from sysreferences where fkeyid = object_id('y') and rkeyid = object_id('x') go drop statistics x.xstat go create clustered index xcidx on x(a) with drop_existing, sort_in_tempdb create unique nonclustered index xpk on x(b) with drop_existing, sort_in_tempdb go print 'sysreferences now out of sync' select * from sysindexes where id = object_id('x') select * from sysreferences where fkeyid = object_id('y') and rkeyid = object_id('x') go dbcc checkcatalog go </li></ol>
