在某些场合下,存储过程或触发器里的SQL语句需要动态生成。Oracle的DBMS_SQL包可以用来执行动态SQL语句。本文通过一个简单的例子来展示如何利用DBMS_SQL包执行动态SQL语句:

 

DECLARE
       v_cursor NUMBER;
       v_stat NUMBER;
       v_row NUMBER;
       v_id NUMBER;
       v_no VARCHAR(100);
       v_date DATE;
       v_sql VARCHAR(200);
       s_id NUMBER;
       s_date DATE;
BEGIN
     s_id := 3000;
     s_date := SYSDATE;
     v_sql := ‘SELECT id,qan_no,sample_date FROM "tblno" WHERE id > :sid and sample_date < :sdate‘;
     v_cursor := dbms_sql.open_cursor; --打开游标;
     dbms_sql.parse(v_cursor, v_sql, dbms_sql.native); --解析动态SQL语句;
     dbms_sql.bind_variable(v_cursor, ‘:sid‘, s_id); --绑定输入参数;
     dbms_sql.bind_variable(v_cursor, ‘:sdate‘, s_date);
     
     dbms_sql.define_column(v_cursor, 1, v_id); --定义列
     dbms_sql.define_column(v_cursor, 2, v_no, 100);
     dbms_sql.define_column(v_cursor, 3, v_date);
     v_stat := dbms_sql.execute(v_cursor); --执行动态SQL语句。
     LOOP
         EXIT WHEN dbms_sql.fetch_rows(v_cursor)<=0; --fetch_rows在结果集中移动游标,如果未抵达末尾,返回1。        
         dbms_sql.column_value(v_cursor, 1, v_id); --将当前行的查询结果写入上面定义的列中。
         dbms_sql.column_value(v_cursor, 2, v_no);
         dbms_sql.column_value(v_cursor, 3, v_date);
         dbms_output.put_line(v_id || ‘;‘ || v_no || ‘;‘ || v_date);
     END LOOP;
     dbms_sql.close_cursor(v_cursor); --关闭游标。
END;

Oracle DBMS_SQL

 
 Version 10.2

General
Note: DMBS_SQL is the traditional form of dynamic SQL in Oracle.

For most purposes native dynamic sql (NDS) will suffice but there are some things the DBMS_SQL package does that can not be done any other way. This page emphasizes those areas where there is no substitute.
