使用Oracle的DBMS_SQL包执行动态SQL语句

 

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;

 

结果：

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.
