mysql jdbc驱动程序不支持多语句触发器中的分隔符

我有一些代码因为一些分号放错了地方而触发了语法错误。如果这是在命令行上运行的，我会用一个分隔符来解决这个问题。不幸的是，jdbc4驱动程序似乎无法识别分隔符。无论如何要让它运行

delimiter |
CREATE TRIGGER obs_update BEFORE UPDATE ON obs
FOR EACH ROW
BEGIN
   IF OLD.voided = 0 AND NEW.voided = 1 THEN
      DELETE FROM clinic_obs WHERE id = OLD.obs_id;
   ELSE
      UPDATE clinic_obs SET clinic_obs.revision_token = NOW()
      WHERE NEW.obs_id = clinic_obs.id;
   END IF;
END;
|
delimiter ;

分隔符是用于SQL客户端的命令。JDBC中不需要使用分隔符。 下面的示例显示了它：

import java.sql.*;

public class TriggerExample {

    public static void main(String args[]) {

        String connectionURL = "jdbc:mysql://localhost:3306/test";
        Connection con = null;

        try {
            Class.forName("com.mysql.jdbc.Driver");
            con = DriverManager.getConnection(connectionURL, "login",
                    "password");
            Statement stmt = con.createStatement();
            stmt.execute("CREATE TRIGGER obs_update BEFORE UPDATE ON obs "
                    + "FOR EACH ROW "
                    + "BEGIN "
                    + "IF OLD.voided = 0 AND NEW.voided = 1 THEN "
                    + "   DELETE FROM clinic_obs WHERE id = OLD.obs_id; "
                    + "ELSE "
                    + "   UPDATE clinic_obs SET clinic_obs.revision_token = NOW() "
                    + "   WHERE NEW.id = clinic_obs.id; "
                    + "END IF; "
                    + "END;");
            con.close();
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (con != null) {
                try {
                    con.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

尝试删除最后一个结束词后的分号。看起来是这样的：

delimiter |
CREATE TRIGGER obs_update BEFORE UPDATE ON obs
FOR EACH ROW
BEGIN
   IF OLD.voided = 0 AND NEW.voided = 1 THEN
      DELETE FROM clinic_obs WHERE id = OLD.obs_id;
   ELSE
      UPDATE clinic_obs SET clinic_obs.revision_token = NOW()
      WHERE NEW.obs_id = clinic_obs.id;
   END IF;
END|

它应该可以工作，因为我使用jdbc驱动程序完成了类似的触发器/过程
