我有一個C#代碼,它引發了一個SQLException,它帶有消息Error將數據類型varchar轉換爲int。有趣的是我沒有在我的代碼中有任何轉換或INT變量。我的存儲過程通過SSMS獨立運行。不使用int轉換爲Int錯誤
這裏是C#位
string[] envData = new string[4];
string dbCon = "";
dbCon = "Database=" + "TestData";
dbCon = dbCon + ";Server=" + "DEV";
dbCon = dbCon + ";Trusted_Connection=Yes;";
using (SqlConnection Con = new SqlConnection(dbCon))
{
Con.Open();
//using (SqlTransaction tr = Con.BeginTransaction("GetEnvironmentInfo"))
//{
string spEnvironmentInfo = @"ELog.GetEnvironmentInfo";
SqlCommand cmd = new SqlCommand(spEnvironmentInfo, Con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@oElogBaseDir", DbType.String));
cmd.Parameters["@oElogBaseDir"].Direction = ParameterDirection.Output;
cmd.Parameters.Add(new SqlParameter("@oElogFinancialMonthDir", DbType.String));
cmd.Parameters["@oElogFinancialMonthDir"].Direction = ParameterDirection.Output;
cmd.Parameters.Add(new SqlParameter("@oElogFinancialYear", DbType.String));
cmd.Parameters["@oElogFinancialYear"].Direction = ParameterDirection.Output;
cmd.Parameters.Add(new SqlParameter("@oElogEmailAccount", DbType.String));
cmd.Parameters["@oElogEmailAccount"].Direction = ParameterDirection.Output;
try
{
cmd.ExecuteNonQuery();
envData[0] = cmd.Parameters["@oElogBaseDir"].Value.ToString();
envData[1] = cmd.Parameters["@oElogFinancialMonthDir"].Value.ToString();
envData[2] = cmd.Parameters["@oElogFinancialYear"].Value.ToString();
envData[3] = cmd.Parameters["@oElogEmailAccount"].Value.ToString();
//tr.Commit();
}
catch (System.Exception ex)
{
//tr.Rollback("GetEnvironmentInfo");
throw ex;
//return null;
}
//}
}
Response.Write(envData[0].ToString());
Response.Write(envData[1].ToString());
Response.Write(envData[2].ToString());
Response.Write(envData[3].ToString());
這裏是SQL語句組成部分
ALTER PROCEDURE [ELog].[GetEnvironmentInfo]
@oELogBaseDir VARCHAR(MAX) OUTPUT,
@oELogFinancialMonthDir VARCHAR(MAX) OUTPUT,
@oELogFinancialYear VARCHAR(MAX) OUTPUT,
@oElogEmailAccount VARCHAR(MAX) OUTPUT
AS
BEGIN
SELECT
@oELogBaseDir = e.ELogBaseDir,
@oELogFinancialMonthDir = e.ELogFinancialMonthDir,
@oELogFinancialYear = e.ELogFinancialYear,
@oElogEmailAccount = e.ElogEmailAccount
FROM SSISMeta.Environment e
WHERE e.SQLServerInstance = @@SERVERNAME
END
這裏是堆棧跟蹤

這是一個SQL錯誤,而不是C#錯誤。 e.ELogFinancialYear的數據類型是什麼? – DavidG
存儲過程自己在SQL中正常工作 – mouliin
如果要重新拋出異常,請使用'throw'並且noe'扔前';' - 那麼你鬆散的堆棧跟蹤。再次運行它並從拋出的異常粘貼堆棧跟蹤。 – TcKs
