const string sql = @"
SELECT *
   FROM V_PROVIDER_WAGE_OVER_REVENUE
WHERE SITE_ID = :SITE_ID 
   AND VENDOR_ID = :VENDOR_ID
   AND date_paid >= :DATE_FROM 
   AND date_paid <= :DATE_TO;";

conn.Query<ProviderWageOverRevenueModel>(sql,new { 
     VENDOR_ID = vendorId,SITE_ID = siteId,DATE_FROM = dateFrom,DATE_TO = dateTo 
}).ToList();

我想知道是否在某些时候(也许在Dapper源内？)我能看到类似的东西：

SELECT *
   FROM V_PROVIDER_WAGE_OVER_REVENUE
WHERE SITE_ID = 199
   AND VENDOR_ID = 17
   AND date_paid >= '01/01/2014' 
   AND date_paid <= '20/11/2014';

我假设参数占位符将被替换为值,但是仔细观察Dapper的来源后,我意识到它只是在iDbCommand上执行查询,所以看完这个question之后就可以看到执行了在.Net内的声明？

我试试这个：

string query = cmd.CommandText;
foreach (DbParameter p in cmd.Parameters)
{
    query = query.Replace(p.ParameterName,p.Value.ToString());
}

但结果似乎并不像我希望的那样：

SELECT *
    FROM V_PROVIDER_WAGE_OVER_REVENUE
WHERE 23411127316 = :23411127316 
    AND 23411076816 = :23411076816
    AND date_paid >= :1/07/2014 10:11:34 PM 
    AND date_paid <= :12/12/2014 12:00:00 AM;
