KEY `i_g_k_v` (`registry_group`,`registry_key`,`registry_value`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4; varchar的长度明明设置的是255啊。怎么会报出767 bytes的错误呢? 我们在看看错误提示: [Err] 1071 - Specified key was too long; max key length is 767 bytes。 这个就是因为联合所以长...

請注意,GetBytes 與 GetSqlBytes 不同,其需要一定大小的陣列緩衝區。 VB 複製 While reader.Read() Dim buffer(4000) As Byte Dim byteCount As Integer = _ CInt(reader.GetBytes(1, 0, buffer, 0, 4000)) End While 使用GetValue 擷取資料 SqlDataReader 的GetValue 方法可將值從指定的資料行位移...
