Summary: ODBC: SQLNumResultCols for prepared statement
Key: IGNITE-12126
URL: https://issues.apache.org/jira/browse/IGNITE-12126
Project: Ignite
Issue Type: Bug
Components: odbc
Affects Versions: 2.7.5
Environment: Windows 7
Reporter: AH
According to ODBC Programmer's Reference, SQLNumResultCols can be called
successfully only when the statement is in the prepared, executed, or
positioned state.
However, it is not working when the statement is in the prepared state and not
yet executed: column count returned is 0.
