在一般的情况下,使用批量fetch的几率并不是很多,但是Oracle提供了这个功能我们最好能熟悉一下,说不定什么时候会用上它。 代码如下:declare cursor c1 is select * from t_depart; v_depart t_depart%rowtype ; type v_code_type is table of t_depart.depart_code%type ; v_code v_code_type ; type ...
FOR i IN 1..500 LOOP Insert INTO t1 VALUES (i); END LOOP; END; / Select COUNT(*) FROM t1; COMMIT; Create or REPLACE FUNCTION p (c_in NUMBER) RETURN NUMBER IS PRAGMA AUTONOMOUS_TRANSACTION; BEGIN -- Every time this is called, write a row to table t2 Insert INTO t2 VALUES (c_...

在Oracle数据库中,游标(Cursor)是一个数据库查询的结果集的引用。它允许你逐行地处理查询结果,而不是一次性地处理整个结果集。游标分为隐式游标和显式游标两种。 显式游标(Explicit Cursor) 显式游标是你在PL/SQL程序中明确声明和操作的游标。当你需要对查询结果进行更复杂的处理时,比如逐行处理查询结果或者需要获...

In this case, the cursor FOR LOOP declares, opens, fetches from, and closes an implicit cursor. However, the implicit cursor is internal; therefore, you cannot reference it. Note that Oracle Database automatically optimizes a cursor FOR LOOP to work similarly to a BULK COLLECT query. Although...
