Question

使用Dapper，下面引發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沒有逗號。它必須與參數有關。 OriginZip和DestZip是varchar(10)。 zips是IEnumerable<int>。我嘗試使用zips作爲參數而不轉換爲字符串。同樣的錯誤。

似乎很直接。我究竟做錯了什麼？

嘗試：

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 });
