取得存儲過程的返回值、輸出參數
帶輸出參數的：
try
{
Database db = DatabaseFactory.CreateDatabase();
DbCommand cmd = db.GetStoredProcCommand("usp_xxx");
db.AddParameter(cmd, "@UserID", DbType.Int32, ParameterDirection.InputOutput, "", DataRowVersion.Current, dict.Get("UserID", 0));
db.AddInParameter(cmd, "@LoginName", DbType.String, dict["LoginName"]);
db.ExecuteNonQuery(cmd);
return DictionaryEx.Create("UserID", db.GetParameterValue(cmd, "@UserID"));
}
catch (Exception)
{
return null;
}
帶返回值：
try
{
Database db = DatabaseFactory.CreateDatabase();
DbCommand cmd = db.GetStoredProcCommand("usp_xxx");
db.AddInParameter(cmd, "@UserID", DbType.Int32, dict["UserID"]);
db.AddParameter(cmd, "@ret", DbType.Int32, ParameterDirection.ReturnValue, "", DataRowVersion.Default, null);
db.ExecuteNonQuery(cmd);
return cmd.Parameters["@ret"].Value;
}
catch (Exception)
{
return null;
}
查詢返回結果集：
try
{
Database db = DatabaseFactory.CreateDatabase();
DbCommand cmd = db.GetStoredProcCommand("usp_xxx");
db.AddInParameter(cmd, "@rowStart", DbType.Int32, dict.Get("rowStart", null));
db.AddInParameter(cmd, "@rowEnd", DbType.Int32, dict.Get("rowEnd", null));
return db.ExecuteDataSet(cmd);
}
catch (Exception)
{
return null;
}
