JDBC批量删除某一用户下的触发器

从另外一个地方导出来的表，再导入的时候，存在百把几十个触发器，用PL/SQL删老是报触发器不存在的异常，但是呢，用SQL查能查出来，删也能删掉。

决定用JDBC的循环来删这些。。。。

 1 public static void deleteTriggers() throws SQLException {
 2         Connection connection = getConnection();
 3 
 4         List<String> triggerNameList = new ArrayList<String>();
 5         String sql = "SELECT  TRIGGER_NAME  FROM ALL_TRIGGERS WHERE OWNER='NJZJLMS'";//OWNER后的一定要大写，否则查不到东西
 6         Statement st = connection.createStatement();
 7         Statement st2 = connection.createStatement();
 8         ResultSet rs = st.executeQuery(sql);
 9         while (rs.next()) {
10             String triggerName = rs.getString("TRIGGER_NAME");
11             if (!triggerName.contains("=")) {
12                 triggerNameList.add(triggerName);
13             }
14         }
15         System.out.println("triggerNameList:" + triggerNameList.size());
16         String sql2 = "";
17         for (int i = 0; i < triggerNameList.size(); i++) {
18             System.out.println("triggerName:"+triggerNameList.get(i));
19         }
20         for (int i = 0; i < triggerNameList.size(); i++) {
21             sql2 = "drop trigger \"" + triggerNameList.get(i) + "\"";//这里triggername一定要用双引号，单引号无效
22             System.out.println("sql2:"+sql2);
23             st2.execute(sql2);
24         }
25         st.close();
26         rs.close();
27         connection.close();
28     }
