Benshell采样器更新Oracle请求抛出错误

Question

我试图运行一个循环，通过一个bean shell采样器在oracle数据库中创建记录，它正在抛出错误，

Response code:500

这个查询在SQL Developer工具上运行得很好。

Answer 1

同意这个评论，你的try，catch和finally块应该是这样的，rest看起来不错。

try {
    pstmt = conn.prepareStatement(Query);
    pstmt.executeUpdate();
}
catch(Throwable ex) {
    log.error("Error message: ", ex);
    throw ex;
}
finally {
    if (rs != null) {
        rs.close();
    }
    if (pstmt != null) {
        pstmt.close();
    }
    if (conn != null) {
        conn.close();
        log.info("!!!! Connection closed to database !!!!");
    }

Answer 2

您应该使用PreparedStatement，删除以下行：

 Statement stmt = conn.createStatement();

并将准备好的语句分配给stmt：

stmt = conn.prepareStatement(Query);
