The LAST_ROW_COUNT function returns the number of rows that have been currently fetched.

<rowcnt> INTEGER LAST_ROW_COUNT

Parameters

rowcnt

Number of row fetched thus far.

Examples

The following example uses the LAST_ROW_COUNT function to display the total number of rows fetched in the query.

DECLARE
    curid          INTEGER;
    v_empno        NUMBER(4);

LAST_ERROR_POSITION

The LAST_ERROR_POSITION function returns an INTEGER value indicating the byte offset in the SQL statement text where the error occurred. The error position of the first character in the SQL statement is at 1.

LAST_ERROR_POSITION RETURN INTEGER;

Examples

The following example demonstrates an anonymous block that returns an error position with the LAST_ERROR_POSITION function.

DECLARE
    curid             INTEGER;
    sql_stmt          VARCHAR2(50) := 'SELECT empno FROM not_exist_table';
    v_position        INTEGER;
BEGIN
    curid := DBMS_SQL.OPEN_CURSOR;
    DBMS_SQL.PARSE(curid, sql_stmt, DBMS_SQL.native);
EXCEPTION WHEN OTHERS THEN
    v_position := DBMS_SQL.LAST_ERROR_POSITION;
    DBMS_OUTPUT.PUT_LINE('error position = ' || v_position);
    DBMS_SQL.CLOSE_CURSOR(curid);
END;

error position = 19
