Pass Parameters To Dapper List - dapper

Question

Need to know the best practice for passing multiple parameters to a dapper list function
I need to pass the #StartDate, #EndDate, #AgentId, #Crc passed into the posted method but not sure exactly how to do it using Dapper. Thanks in advance
public List<CallSearchRepositoryBO> GetCallSearchRecords(DateTime startDate, DateTime endDate, int agentId, string crc)
{
try
{
using (IDbConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["CCWorkforceConnectionString"].ConnectionString))
{
var items = connection.Query<CallSearchRepositoryBO>
("SELECT h.historyid " +
" ,h.Dialid " +
" ,h.Crc " +
" ,c.szExternalId ExternalId " +
" ,a.AgentId " +
" ,UPPER(a.LastName +',' +a.FirstName) Agent" +
" ,c.ContactId" +
" ,CallDateTime" +
" ,h.ProjName Campaign" +
" ,h.PhoneNum PhoneNumber" +
" ,szQ01 Q1" +
" ,szQ02 Q2" +
" ,szQ03 Q3" +
" ,szQ04 Q4" +
" ,szQ05 Q5" +
" ,szQ06 Q6" +
" ,szQ07 Q7" +
" ,szQ08 Q8" +
" ,szQ09 Q9" +
" ,szQ10 Q10" +
" ,txtQ33 Comments" +
" ,szFaxType AlertType" +
" ,r.VoxFilePath+VoxFileName RecordingPath" +
" ,r.RecLength" +
" ,CASE WHEN DataLength(txtQ33) > 0 THEN 1 ELSE 0 END HasComments " +
" FROM Touchstar..History h" +
" INNER JOIN Touchstar..Agent a WITH(NOLOCK) ON h.AgentId = a.AgentId" +
" INNER JOIN Touchstar..Recording r WITH(NOLOCK) ON h.HistoryId = r.HistoryId" +
" LEFT JOIN Touchstar..Contact c WITH(NOLOCK) ON h.DialId = c.DialId" +
" LEFT JOIN Touchstar..Sales s WITH(NOLOCK) ON c.ContactId = s.ContactId" +
" WHERE h.CallDateTime BETWEEN #StartDate AND #EndDate" +
" AND h.AgentId=#AgentId"+
" AND h.Crc=#Crc," +
" AND c.szCampaignId IN('UP2','UP4')" +
" ORDER BY CallDateTime DESC").ToList();
return items;
}
}
catch (Exception)
{
throw;
}
}

Answer 1

Pass through an object as a second parameter to the Query function. Notice the extra parameter in the below code "new {StartDate = startDate, EndDate = endDate, AgentId = agentId, Crc = crc}"
var items = connection.Query<CallSearchRepositoryBO>
("SELECT h.historyid " +
" ,h.Dialid " +
" ,h.Crc " +
" ,c.szExternalId ExternalId " +
" ,a.AgentId " +
" ,UPPER(a.LastName +',' +a.FirstName) Agent" +
" ,c.ContactId" +
" ,CallDateTime" +
" ,h.ProjName Campaign" +
" ,h.PhoneNum PhoneNumber" +
" ,szQ01 Q1" +
" ,szQ02 Q2" +
" ,szQ03 Q3" +
" ,szQ04 Q4" +
" ,szQ05 Q5" +
" ,szQ06 Q6" +
" ,szQ07 Q7" +
" ,szQ08 Q8" +
" ,szQ09 Q9" +
" ,szQ10 Q10" +
" ,txtQ33 Comments" +
" ,szFaxType AlertType" +
" ,r.VoxFilePath+VoxFileName RecordingPath" +
" ,r.RecLength" +
" ,CASE WHEN DataLength(txtQ33) > 0 THEN 1 ELSE 0 END HasComments " +
" FROM Touchstar..History h" +
" INNER JOIN Touchstar..Agent a WITH(NOLOCK) ON h.AgentId = a.AgentId" +
" INNER JOIN Touchstar..Recording r WITH(NOLOCK) ON h.HistoryId = r.HistoryId" +
" LEFT JOIN Touchstar..Contact c WITH(NOLOCK) ON h.DialId = c.DialId" +
" LEFT JOIN Touchstar..Sales s WITH(NOLOCK) ON c.ContactId = s.ContactId" +
" WHERE h.CallDateTime BETWEEN #StartDate AND #EndDate" +
" AND h.AgentId=#AgentId"+
" AND h.Crc=#Crc," +
" AND c.szCampaignId IN('UP2','UP4')" +
" ORDER BY CallDateTime DESC", new {StartDate = startDate, EndDate = endDate, AgentId = agentId, Crc = crc}).ToList();
