Dapper解析字符串错误 [英] String parsing error with Dapper

问题描述

我有以下表格：

CREATE TABLE [dbo].[TERMINAL] (
    [TERM_CODEID]    SMALLINT     NOT NULL,
    [TERM_ACTIVE]    SMALLINT     NOT NULL,
    [TERM_NAME]      VARCHAR (30) NOT NULL,
    [TERM_SLA]       CHAR (8)     NOT NULL,
    [TERM_SERIAL]    VARCHAR (8)  NULL,
    [TERM_VERSION]   VARCHAR (8)  NULL,

    [TERM_STATUS]    INT          NULL,
)

当我尝试以下Dapper代码 - 我是一个完整的Dapper新手，昨天发现 - 我得到一个错误：

When I try the following Dapper code - and I'm a complete Dapper novice, found it yesterday - I get an error:

using (var conn = new SqlConnection("data source=ourServer; initial catalog=ourDb;user id=sa;password=ourPassword;"))
{
    conn.Open();
    var terms = conn.Query<Terminal>("select * from TERMINAL");
}

错误是：

解析第3列时发生错误（TERM_SLA = 01010B01 - String）

Error parsing column 3 (TERM_SLA=01010B01 - String)

任何东西应该甚至必须'解析'一个字符串，不要在这样做时遇到错误。可能导致这种情况>

I can see no reason why anything should even have to 'parse' a string, never mind experience an error while doing so. What could be causing this>

推荐答案

Dapper $ c> .NET 数据类型与数据库中的完全相同。 Term_Sla 需要为 String 。

Dapper expects the .NET data type to be exactly the same as in your database. Term_Sla needs to be of type String.
