Parse and execute a statement, then fetch the first result row.
This function is a quick combination of ora_parse(), ora_exec() and ora_fetch().
This function returns a cursor index or FALSE on failure. Details about the error can be retrieved using the ora_error() and ora_errorcode() functions.
There is no direct replacement for ora_do() in oci8. Instead, use a sequence of oci_parse(), oci_excute(), and one of the oci_fetch_*() functions.
