maybe someone here can help me understand why I am getting this strange behaivor.

I am connecting to a MS SQL server from PHP by the ODBC module, I use unixODBC-2.2.9-1, freetds-0.63-1.2.el4.rf and php-4.3.9-3.9 all but the freetds package came with CentOS-4.2 + updates

the problem is that I am getting -1 from the odbc_num_rows(); function, I search the net and it looks that this is a very common problem with MS SQL server and unix ODBC driver, but, my surprise came when I use the isql command (came with the unixODBC package) and the number of rows is returned correctly in the same machine and with the same query. the following is the output from isql command:

+--------------+-----------+---------------------------------------+ SQLRowCount returns 2516 2516 rows fetched SQL>

then I look forward in the source files and I found that both clients (php module and isql) use the same function to get the number of rows:

from isql.c :

static void WriteFooterNormal( SQLHSTMT hStmt, SQLCHAR *szSepLine, SQLLEN nRows ) { SQLLEN nRowsAffected = -1;

printf( (char*)szSepLine );

SQLRowCount( hStmt, &nRowsAffected ); printf( "SQLRowCount returns %d\n", nRowsAffected );

if ( nRows ) { printf( "%d rows fetched\n", nRows ); } }

from odbc php module php_odbc.c :

/* {{{ proto int odbc_num_rows(resource result_id) Get number of rows in a result */ PHP_FUNCTION(odbc_num_rows) { odbc_result *result; SDWORD rows; pval **pv_res; if (zend_get_parameters_ex(1, &pv_res) == FAILURE) { WRONG_PARAM_COUNT; } ZEND_FETCH_RESOURCE(result, odbc_result *, pv_res, -1, "ODBC result", le_result); SQLRowCount(result->stmt, &rows); RETURN_LONG(rows); } /* }}} */

so I get confuse, why an odbc client get the right result and the other don't if both use the same query, same odbc configuration, same libraries files, same driver (freetds)

I am a complete newbie with odbc, MS SQL and freetds :-( and with very litle knowledge of php modules

can anybody help me ?

thanks in advance roger
