我总是得到这个错误

“s”附近：语法错误

我的实现：

litecon.ConnectionString = "Data Source=" + AppAddress + "\\database\\mynew22.db;Version=3;UTF16Encoding=True";

从此方法收到错误 -> liteda.Fill(dt);

        if (lang == "FaToMe")
            liteda.SelectCommand = new SQLiteCommand("select * from mey where trans like '%" + str + "%'", litecon);
        else
            liteda.SelectCommand = new SQLiteCommand("select * from mey where pe like '%" + str + "%'", litecon);

        DataTable dt = new DataTable();
        liteda.Fill(dt); //liteda is SQLiteDataAdapter

此选择命令之间没有区别...

"select * from mey where pe like '%" + str + "%'"

或者

"select eng "

总是在“s”附近说：语法错误

但如果使用“xselect * from mey”，请在“x”附近说：语法错误

我正在使用这个库 http://adodotnetsqlite.sourceforge.net/

When str has a value containing an apostrophe, this query will not work because the string will be terminated too early:

select * from mey where trans like '%King Solomon's Mines%'

You must use parameters:

cmd = new SQLiteCommand("select * from mey where trans like @pattern", litecon);
cmd.Parameters.AddWithValue("@pattern", "%" + str + "%");

问题通常与撇号有关。您可以使用它们，但必须像另一个答案中提到的那样加倍，

select * from mey where trans like '%King Solomon's Mines%' 应改为 select * from mey where trans like '%King Solomon''s Mines%'.

一个快速的解决方案是"select * from mey where trans like "+"'%King Solomon's Mines%'".Replace("'","''")

这无论如何都会成功。
