使用LIMIT命令和Java中的Prepared Statement的MySQL语法错误 [英] MySQL syntax error using LIMIT command with Prepared Statement in Java

问题描述

我正在用Java编写代码，我想每次在MySQL表的下一行运行此代码.第二次运行此代码.

I am writing code in Java and I want to take every time I run this code the next line from a MySQL table.The second time I run this code is this.

String timh1 = "1";
String timh2 = "2";
PreparedStatement st = null;
String sqlGrammes = "SELECT SURNAME ,KATHGORIA, AFM , NAME FROM EMPLOYEE LIMIT ?,? ";
try {
    st = connection.prepareStatement(sqlGrammes);
    st.setString(1, timh1);
    st.setString(2, timh2);

但是它显示了这个错误:

But it shows me this error :

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:您的SQL语法有错误；检查与您的MySQL服务器版本相对应的手册以获取正确的语法，以在第1行的"1"，"2"附近使用

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''1','2'' at line 1

推荐答案

limit接受整数参数，因此您应该使用int s，而不是String s:

limit accepts integer parameters, so you should use ints, not Strings:

int timh1 = 1;
int timh2 = 2;
PreparedStatement st = null;
String sqlGrammes = "SELECT SURNAME ,KATHGORIA, AFM , NAME FROM EMPLOYEE LIMIT ?,? ";
try {
    st = connection.prepareStatement(sqlGrammes);
    st.setInt(1, timh1); // notice the setInt
    st.setInt(2, timh2); // here too
