Returns an ODBC connection id or 0 (&false;) on
|
|
error.

|
|
The connection id returned by this functions is needed by other
|
|
ODBC functions. You can have multiple connections open at once as long as
|
|
they either use different db or different credentials.
|
|
The optional fourth parameter sets the type of cursor to be used
|
|
for this connection. This parameter is not normally needed, but
|
|
can be useful for working around problems with some ODBC drivers.
|
|
</simpara>
|
|
<simpara>
|
|
With some ODBC drivers, executing a complex stored procedure may
|
|
fail with an error similar to: "Cannot open a cursor on a stored
|
|
procedure that has anything other than a single select statement
|
|
in it". Using SQL_CUR_USE_ODBC may avoid that error. Also, some
|
|
drivers don't support the optional row_number parameter in
|
|
<function>odbc_fetch_row</function>. SQL_CUR_USE_ODBC might help
|
|
in that case, too.
