Description
resource 
oci_parse ( resource connection, string query)
     oci_parse() prepares the query
     using connection and returns the statement
     identifier, which can be used with
     oci_bind_by_name(), oci_execute()
     and other functions.
    
注: 
      This function does not validate
      query. The only way to find out if
      query is valid SQL or PL/SQL statement - is to
      execute it.
     
     oci_parse() returns FALSE on error.
    
注: 
      In PHP versions before 5.0.0 you must use ociparse() instead. 
      This name still can be used, it was left as alias of
      oci_parse() for downwards compatability. 
      This, however, is deprecated and not recommended.
