SQL 2005 brings many breaking changes that need to be adressed when preparing migrations from previous versions. Here is a brief look at some changes in error messages from SQL 2000 to SQL 2005. These aren't (or at least shouldn't be) vital to the majority of migration cases; still, this post (and the next one) provides an overview, that may prove to be useful - if only for a moment or two.
| Error 1945 (SQL 2005) Severity 10 | Error 1945 (SQL 2000) Severity 16 |
| Warning! The maximum key length is %d bytes. The index "%.*ls" has maximum length of %d bytes. For some combination of large values, the insert/update operation will fail.
(Same message text in SQL 2000.) Comments: What is effectively a warning in SQL 2000 becomes a proper warning in SQL 2005. The index is created even if the maximum length is exceeded. However, the statement that violates this constraint will be aborted. | |
| Error 2519 (SQL 2005) Severity 10 | Error 2519 (SQL 2000) Severity 16 |
| Computed columns and user-defined types cannot be checked for object ID %ld (object "%.*ls") because the internal expression evaluator could not be initialized.
Different message text in SQL 2000: Unable to process table %.*ls because filegroup %.*ls is invalid. Comments: A clear indication of the fact that error numbers are subject to change and can be reused in later versions. | |
| Error 2594 (SQL 2005) Severity 10 | Error 2594 (SQL 2000) Severity 16 |
| Cannot process index "%.*ls" of table "%.*ls" because one of its partitions exists on the filegroup "%.*ls", which was not checked.
Different message text in SQL 2000: Invalid index ID (%d) specified. Comments: An error in SQL 2000 becomes a more verbose warning in SQL 2005. | |
| Error 2595 (SQL 2005) Severity 10 | Error 2595 (SQL 2000) Severity 16 |
| Cannot process table "%.*ls" because one of the partitions for its base index exists on the filegroup "%.*ls", which was not checked.
Different message text in SQL 2000: Database "%.*ls" must be set to single user mode before executing this statement. Comments: Another case of "mistaken identity" -i.e. error numbers being reused. | |
| Error 3018 (SQL 2005) Severity 10 | Error 3018 (SQL 2000) Severity 16 |
| The restart-checkpoint file "%ls" was not found. The RESTORE command will continue from the beginning as if RESTART had not been specified.
Different message text in SQL 2000: There is no interrupted backup or restore operation to restart. Reissue the statement without the RESTART clause. Comments: When the RESTART option of the RESTORE command is specified incorrectly in SQL 2000 the restoration is interrupted, while in SQL 2005 the restoration continues and the fawlty option is ignored. Also see message 3028. | |
| Error 3028 (SQL 2005) Severity 10 | Error 3028 (SQL 2000) Severity 16 |
| The restart-checkpoint file "%ls" was corrupt and is being ignored. The RESTORE command will continue from the beginning as if RESTART had not been specified.
Different message text in SQL 2000: Operation checkpoint file is invalid. Could not restart operation. Reissue the statement without the RESTART option. Comments: When the RESTART option of the RESTORE command is specified incorrectly in SQL 2000 the restoration is interrupted, while in SQL 2005 the restoration continues and the fawlty option is ignored. Also see message 3018. | |
| Error 3175 (SQL 2005) Severity 10 | Error 3175 (SQL 2000) Severity 16 |
| RESTORE FILEGROUP="%ls" was specified, but not all of its files are present in the backup set. File "%ls" is missing. RESTORE will continue, but if you want all files to be restored, you must restore other backup sets.
Different message text in SQL 2000: The filegroup "%ls" cannot be restored because all of the files are not present in the backup set. File "%ls" is missing. Comments: Restoring databases in SQL 2005 becomes slightly less of a burdon on the DBA. When restoring filegroups all available files are restored, thanks to a more advanced SQL 2005 architecture. | |
| Error 3281 (SQL 2005) Severity 10 | Error 3281 (SQL 2000) Severity 16 |
| Released and initiated rewind on "%ls".
(Same message text in SQL 2000.) Comments: Another "warning" (SQL 2000) becomes a proper warning in SQL 2005. | |

| Index ID %d, partition ID %I64d, alloc unit ID %I64d (type %.*ls). FirstIAM %S_PGID. Root %S_PGID. Dpages %I64d.
Different message text in SQL 2000: Index ID %ld. FirstIAM %S_PGID. Root %S_PGID. Dpages %ld. Comments: Another error in SQL 2000 becomes a more verbose warning in SQL 2005. But does that make it easier to understand? | |
| Error 7925 (SQL 2005) Severity 10 | Error 7925 (SQL 2000) Severity 16 |
| Index ID %d, partition ID %I64d, alloc unit ID %I64d (type %.*ls). %I64d pages used in %I64d dedicated extents.
Different message text in SQL 2000: Index ID %d. %ld pages used in %ld dedicated extents. Comments: See previous. | |
| Error 7927 (SQL 2005) Severity 10 | Error 7927 (SQL 2000) Severity 16 |

| QueryInterface failed for "%ls": %ls.
Different message text in SQL 2000: QueryInterface failed for "%hs": %hs. Comments: Even fatal errors in SQL 2000 can be treated as warnings in SQL 2005. | |
| Error 8625 (SQL 2005) Severity 10 | Error 8625 (SQL 2000) Severity 16 |
| Warning: The join order has been enforced because a local join hint is used.
(Same message text in SQL 2000.) Comments: Another "warning" (SQL 2000) becomes a proper warning in SQL 2005. | |
| Error 8975 (SQL 2005) Severity 10 | Error 8975 (SQL 2000) Severity 16 |
| Indexed view check failed for indexed view %.*ls (object ID %d) due to internal query error %d, severity %d, state %d. Refer to Books Online for more information on this error. This does not necessarily represent an integrity issue with the data in this database. However, this view will not be processed further.
Different message text in SQL 2000: Table error: Object ID %d, index ID %d. The child page pointer %S_PGID on PageId %S_PGID, slot %d is not a valid page for this database. Comments: Another error number being reused. | |
