ADO.NET vs. Query Analyzer: Inconsistent Results
Can anybody explain the following behaviour?
In SQL Query Analyzer:
EXEC GetStatistics 0, 7, 2004
(1 row of data returned - the correct result)
// SqlConnection connection; // connects successfully
// SqlCommand command; // initialized with the query from above, the appropriate parameters, and the connection
DataSet ds = new DataSet();
SqlDataAdapter adapter = new SqlDataAdapter( command );
int numRows = adapter.Fill( ds );
// numRows == 4
// four rows are returned, when there should only be one.
I've checked and rechecked all the parameters, the query text itself -- the lot -- and I can't work out what's going on.
Can anybody shed some light as to why this may be happenning?

Query Analizer and ADO.Net use (by default) different connection settings so e.g. terms like
may return different results with different connection settings (ANSI, ...) because "= NULL" is treated differently.
SELECT * FROM MyTable WHERE SomeColumn = NULL
Can you please post your sql statement?
