How can I get more information about the SQL warning in PHP?

I'm trying to access an Oracle database in PHP, but it throws the following error:

Warning: oci_execute(): in PATH_TO_FILE.php on line XXX

without further information ...

I am doing the following on this line ...

oci_free_statement($stmt);
$consulta="LOAD DATA CONCURRENT LOCAL INFILE 'files/data.csv' 
          INTO TABLE PRUEBA_SMS FIELDS TERMINATED BY ';' 
          LINES TERMINATED BY '\n' 
          (@FECHA,NODO,SERVICIO,VALOR) 
 SET FECHAHORAINF=TO_DATE(@FECHA,'DD/MM/YYYY hh24:mi:ss')";
$stmt=oci_parse($conexion, $consulta);
oci_execute($stmt);

      

        
        
        
      

    

Is there a way to find out more about this warning and why it fails?

UPDATE . Well, after researching, I think the problem is that the procedure is LOAD DATA INFILE

incompatible with the SQL database, only if it was MySQL. I tried to run this command in Oracle SQL Plus program and it generates the following error ...

SP2-0734: unknown command beginning "LOAD DATA ... " Rest of the line ignored
