Question

I have a question about query in Oracle :

The problem is, the result of oci_num_rows is always 0.

and here is my code so far :

  $qu         


        

Answer 1

This function does not return number of rows selected! For SELECT statements this function will return the number of rows, that were fetched to the buffer with oci_fetch*() functions.

Try this to check either your the credentials of your connection are correct or not.
