This example illustrates how you can create and use dynamic cursor in Oracle PL/SQL. The example is pretty simple, but I hope you can get the idea and apply it to more complicated cases. DECLARE t_cursorISREF CURSOR; my_cursor t_cursor; v_customer RECORD(customer_id NUMBER(18),amount ...

This ensures that * ORACLE does not keep parse locks on tables after data * manipulation operations, so that subsequent data definition * operations on those tables do not result in a parse-lock * error. */ EXEC ORACLE OPTION (RELEASE_CURSOR=YES); void dyn_error(); main() { /* ...
How do values get stored in these data variables? Output values are FETCHed using a cursor, and input values are filled in by your program, typically from information entered interactively by the user. How Is the Information Obtained?
cursor_name INTEGER; rows_processed INTEGER; v_stmt CLOB := NULL; v_role VARCHAR2(20) := 'CPPM_ADMIN'; v_user VARCHAR2(20) := 'wbmarsh1'; BEGIN BEGIN cursor_name := DBMS_SQL.OPEN_CURSOR; DBMS_SQL.PARSE(cursor_name,'GRANT :role TO :user',DBMS_SQL.NATIVE); ...
在上面的示例中,首先使用OPEN_CURSOR函数打开一个游标,然后使用PARSE函数解析SQL语句,使用BIND_VARIABLE函数绑定变量的值,使用DEFINE_COLUMN函数定义结果列,使用EXECUTE函数执行SQL语句,使用FETCH_ROWS函数获取结果行数,最后使用COLUMN_VALUE函数获取结果值。 总结:生成动态PL/SQL可以使用动态SQL语句或者DBMS_SQL包。动态SQL...
For (2), the consumer needs to use the UDFinndob_redo_log_consumer_advance(lsn)to move the cursor forward manually. The session needs to be ended to de-register the consumer. And finally, when clone (3) is in progress, we register clone’s consumer and clone knows how and then to ...
