MSSQLSERVER_948

[!INCLUDE SQL Server]

Details

Attribute Value
Product Name SQL Server
Event ID 948
Event Source MSSQLSERVER
Component SQLEngine
Symbolic Name NA
Message Text The database '%.*ls' cannot be opened because it is version %d. This server supports version %d and earlier. A downgrade path is not supported.

Explanation

Certain features in [!INCLUDEssNoVersion] affect the structure of the database files. When you attach a database to another instance of [!INCLUDEssNoVersion], the file format might not be compatible with a different version of the [!INCLUDEssDE].

For example, this error can be caused by using the vardecimal storage format in a later version of [!INCLUDEssNoVersion] and then trying to attach the database files in a version earlier than [!INCLUDEssVersion2005] Service Pack 2.

User Action

Determine the version of [!INCLUDEssNoVersion] that is running on the originating server. In [!INCLUDEssManStudioFull], either right-click the server and then click Properties or type SELECT @@VERSION in a query window. Open the database by using the original version of [!INCLUDEssNoVersion]. Investigate the features that are enabled on the original database in the instance of [!INCLUDEssNoVersion]. Modify these settings to work with the version of [!INCLUDEssNoVersion] in which the database will be attached.
