This article was previously published under Q175904
BUG #: 17322 (6.50)
SYMPTOMS
Multiple threads, each allocating its own HSTMT using server cursors
(active statements) sharing a single connection, cause the following error
on prepared execution of a SQL statement:
S1000: [Microsoft][ODBC SQL Server Driver] Connection is busy with
results for another hstmt
WORKAROUND
To work around this problem, use SQLExecDirect statements instead of
SQLPrepare and SQLExecute when using multiple active HSTMTs (on different
threads) and server cursors.
STATUS
Microsoft has confirmed this to be a problem in SQL Server version 6.5 and
Open Database Connectivity version 3.0. We are researching this problem and
will post new information here in the Microsoft Knowledge Base as it
becomes available.
