BUG #: 102563 (SQLBUG_70)
SYMPTOMS
If you try to run a linked server query against a Wonderware's remote provider, INSQL, and a LIKE predicate exists in the WHERE clause, the
following error message may occur:
Server: Msg 7320, Level 16, State 2, Line 3
Could not execute query against OLE DB provider 'INSQL'.
[OLE/DB provider returned message: InSQL did not receive a WHERE clause from SQL Server. If one was specified, refer to the InSQL OLE DB
documentation]
This error message can occur if you are using a computer that is running Microsoft SQL Server 7.0 Service Pack 3.

NOTE: Because of file dependencies, the most recent hotfix or feature that contains the files may also contain additional files. STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION
Beginning with this hotfix (post service pack 4 build 1070), to make sure that the LIKE criteria is remoted to a provider when you run a linked server query, SQL Server checks the SQLServerLIKE provider registry entry. When the SQLServerLIKE provider entry exists and is set (key is equal to 1), if a LIKE predicate exists in a linked server query it is remoted to the provider.
SQL Server determines the remotability of the LIKE predicate when it runs a linked server query. The SQLServerLIKE provider key was introduced to ease the restrictions that dictate the remotability of the LIKE predicate.
The SQLServerLIKE provider key is a cumulative setting. When set, it also implies DateLiteral support by the provider.
