BUG: SQLFreeStmt After SQLExecute/SQLExecDirect May Cause GPF (113510)
The information in this article applies to:
- Microsoft Open Database Connectivity 1.0
This article was previously published under Q113510
BUG# ODBCDBASE: 2062 (1.01.1928)
SYMPTOMS
On certain Btrieve Tables, the following sequence of operations (or
equivalent) can generate a general protection fault (GP fault) in
BTRV110.DLL:
- Allocate a Env, Hdbc, and Stmt handle using SQLAllocEnv,
SQLAllocConnect, and SQLAllocStmt respectively or an equivalent
sequence of calls to prepare to execute a SQL statement.
- Execute SQLExecDirect or SQLExecute to execute a selection query
(select * from <tablename>).
- A subsequent call to SQLFreeStmt with fOption = SQL_CLOSE.
The exact message of the error generated is:
<Application name> caused a general protection fault in module
BTRV110.DLL at 0011:0B7A.
NOTE: The conditions under which this can happen are highly dependent on
the combination of specific data in certain tables and the structure of the
ddf files.
WORKAROUND
Try copying the data out and moving into another table. Run your query
against the new table.
STATUS
Microsoft has confirmed this to be a problem in ODBC Btrieve Driver version
1.01.1928. We are researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.
