One of the SELECT fails using unixOdbc - SQLSTATE[24000]: Invalid cursor state

Question

I am running Ubuntu 13.10 with FreeTDS and ODBC (package: php5-odbc) installed. I use tds version = 8.0, but also tried tds version = 7.2.

I am using PDO and this is my DSN:

$dsn = sprintf('odbc:Driver=FreeTDS;Server=%s;Port=1433;Database=%s', DB_SQL_SERVERNAME, DB_DB_NAME);

I connect to MSSQL instance and perform some INSERT/SELECT queries using transactions, however I can not figure out why this query fails:

SELECT id 
FROM tblColumns 
WHERE siteID = 10063 AND 
    typeID = 1000 AND 
    extendedTypeID = 18 AND 
    label = 'RwThiFc85A'

giving error:

SQLSTATE[24000]: Invalid cursor state: 0 [FreeTDS][SQL Server]Invalid cursor state (SQLExecute[0] at /build/buildd/php5-5.5.3+dfsg/ext/pdo_odbc/odbc_stmt.c:254)

I am running bunches of similiar queries before and they are performed well, e.g.:

SELECT id 
FROM tblColumns 
WHERE siteID = 10063 AND 
    typeID = 1000 AND 
    extendedTypeID = 3 AND 
    label = 'VwThiFc91B'

Do you have ideas why it happens?

I did not have such a issues with dblib and sqlsrv, however now I am on Unix and can not use sqlsrv, and due to issues with dblib UTF-8 encoding I am trying to use ODBC.

It looks you have two different result sets open at the same time. You have to finish processing your first ResultSet and close it so you can re-use the Statement to create the second ResultSet.
