I'm exploring full text index searching using SQL Server 2008 and encounter two sets of errors.
It stems from a a stored procedure I call with VBScript which generates would generate search hit list recordset. The stored procedure runs fine in SQL Server Management studio and basically generates a search hit list. Arguments are keyword, and style for highlighting.
Initially error:
Error One: ADODB.Recordset error '800a0e78 Operation is not allowed when the object is closed
at the If not recordset.EOF
line in the to ASP code. Then a bit of reading and searching pointed having SET NOCOUNT ON;
especially when referencing temporary tables (KB235340).
However when I specify SET NOCOUNT ON
I get the error listed in "error two". NB regarding permissions I have EXECUTE permission assigned to the account running the stored procedure to highlight the search hits.
Error Two: Microsoft OLE DB Provider for SQL Serve error '80040e14' The user does not have permission to perform this action
Error Two occurs when add the SET NOCOUNT ON
.
ASP Code: Line causing the error is highlighted

The sys.dm views you use require elevated permissions
- sys.dm_fts_parser = sysadmin
- sys.dm_fts_index_keywords_by_document = CREATE FULLTEXT CATALOG
As you mentioned, you are using 2 different sets of credentials.
You are sysadmin in SSMS and plain user from vb script.
You can try "EXECUTE AS OWNER" in the stored procedure. Or try wrapping sys.dm_fts_parser in a view in master (also with EXECUTE AS OWNER)
