dapper - 小巧玲珑

Question

下面使用Dapper抛出Incorrect syntax near ','。

const string sql = 
    "select * from ZipToZipDistance z where z.NoRouteFound = 0" +
    " and z.OriginZip in (@zips) or z.DestZip in (@zips)";
var zipStrings = zips.Select(x => x.ToString()).ToArray();
var result = connection.Query<ZipToZipDistance>(sql, 
    new { zips = zipStrings });

嗯，SQL没有逗号。它必须与参数有关。 OriginZip和 DestZip是 varchar(10)。 zips是 IEnumerable<int>。我尝试使用 zips作为参数而不转换为字符串。同样的错误。

似乎很简单。我究竟做错了什么？

尝试:

const string sql = 
const string sql = 
    "select * from ZipToZipDistance z where z.NoRouteFound = 0" +
    " and z.OriginZip in @zips or z.DestZip in @zips";
var zipStrings = zips.Select(x => x.ToString());
var result = connection.Query<ZipToZipDistance>(sql, 
    new { zips = zipStrings });
