我收到以下错误：
您的SQL语法有错误;检查与您的MariaDB服务器版本相对应的手册，以获得正确的语法，以便使用近似值（＆＃39;火箭联盟＆＃39;＆＃39;火箭联盟/ c125w9bg2k0v＆＃39;，＆＃39; ; 2016-02-17＆＃39;，＆＃39; Psyonix，In＆＃39;第1行＆＃34;
如果我尝试手动插入数据，我也有问题。如您所见，类型为VARCHAR。
编辑完成。
我遇到了将代码从java引入Mysql中的表的问题。
首先我创建表格，如果它不存在：
for (int i = 1; i<listaEmpresaA.length; i++) { //la fila 1 es la del header que no nos interesa
for (int j=0; j<1; j++) {
st.executeUpdate("INSERT INTO Xbox_One (Juego, URL, Publicado, Lanzamiento, Descripcion, Pegi, Descripcion_Pegi, nota, "

+ ")");
}
}
此步骤正确，表已创建。问题是我找不到引入数据的方法，数据存储在名为listaEmpresaA的二维数组中。
以下是我正在使用的代码：
{{1}}
可能有点乱，但我还没有找到任何其他办法。
如果您能给我一些提示或指出错误，我将不胜感激。执行中没有错误。
感谢您的建议。
答案 0 :(得分：1)
这将通过PreparedStatement完成。
这对于防止SQL注入很有用，如果执行相同的查询，它将更有效。
首先，使用?准备语句，以指定循环外参数的位置。
PreparedStatement ps = conn.preparedStatement(
"insert into MY_TABLE (A,B,C,D) values (?,?,?,?)"
):
这将预编译查询。然后，您只需使用循环中为每个实例提供的setter（取决于类型）设置值
ps.setString(1, instance.getA());
ps.setString(2, instance.getB());
ps.setString(3, instance.getC());
ps.setString(4, instance.getD());
<强> !!该指数是基于1的!!!
当然，在这里你应该在数据数组上使用循环来设置值
您只需要使用PreparedStatement.execute()执行此语句。您可以反复重复使用相同的语句（在循环中），只需清除参数即可。
这看起来像是：
PreparedStatement ps = conn.preparedStatement(
"INSERT INTO Xbox_One (Juego, URL, Publicado, Lanzamiento, Descripcion, "
..... + ") VALUES (?,?,?,?,? .... )";
);
for(String[] array : listaEmpresaA){
for(int i = 0; i < 95; ++i){ //Careful to an arrayoutofbounds exception, but every parameter MUST BE SET
ps.setString(i+1, array[i]); //Can't be null, if so, must use setNull(i+1);
}
ps.execute();
}
编辑：
您得到的错误来自您编写的查询。通过打印您使用的String，我得到了这个
INSERT INTO Xbox_One (
Juego, URL, Lanzamiento, ... , UK_sin_Gold, UK_EA))
VALUES (
?,?,?, ... ,?,?)
然后你会看到在VALUES之前有两个括号，而不是一个
