所以我有一个搜索返回工作......但它没有在数据库中找到确切的条目......

当我搜索＆＃34; e7af78997ef220a557c97a1a4c11e0c2＆＃34; 这是一个人员ID时，它会返回＆＃34; fa32f7c456b368e17a278f3b165a550d＆＃34; 这完全是不同的人ID。
如果我将查询更改为MySqlConnection con = new MySqlConnection(dbConnection);
MySqlCommand cmd;
con.Open();
MySqlDataReader dbReader;
string cmdText = "SELECT `BanID`, `GUID`, `BanTime`, `Reason`, `BanType`, `Proof` FROM `a3bans`.`bans` WHERE `GUID` LIKE @pGUID";
cmd = new MySqlCommand(cmdText, con);
cmd.Parameters.AddWithValue("@pGUID", "%" + bans.GuidOrIP + "%");
GUID WHERE，则会返回= @prmGUID"值。
我做错了什么，它不会返回我正在寻找的字符串？
答案 0 :(得分：0)
MySqlConnection con = new MySqlConnection(dbConnection);
MySqlCommand cmd;
con.Open();
MySqlDataReader dbReader;
string cmdText = "SELECT `BanID`, `GUID`, `BanTime`, `Reason`, `BanType`, `Proof` FROM `a3bans`.`bans` WHERE `GUID` LIKE '%@pGUID%'";
cmd = new MySqlCommand(cmdText, con);
SqlParameter param = new SqlParameter();
param.ParameterName = "@pGUID";
param.Value = bans.GuidOrIP;
cmd.Parameters.Add(param);
通过使用此代码，它将在表中查找相同的bans.pGUID，然后返回结果。 试试吧。

它实际上与此无关，大声笑我有两个非常相似的变量，让它们混淆了......
