I get this timeout error:
Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding
Script task executes stored procedure that takes some time. If I change parameter in a stored procedure to retrieve less data then it works fine. So I am assuming I have to increase the connection timeout in my code. But I don't know where exactly should I do that?
I tried to change Connect Timeout in connection manager - but it didn't help.
I also tried this:
cmd.CommandTimeout = 500;
But still - no success.
I guess I need to do that somewhere in a code:
public void Main()
{
string datetime = DateTime.Now.ToString("yyyyMMddHHmmss");
DateTime startDate = DateTime.Now.AddMonths(-1).AddDays(1 - DateTime.Now.Day);
DateTime endDate = startDate.AddMonths(1).AddDays(-1);
//var now = DateTime.Now;
//var firstDayCurrentMonth = new DateTime(now.Year, now.Month, 1);
//var lastDayLastMonth = firstDayCurrentMonth.AddDays(-1);
try
{
//Declare Variables
// string ExcelFileName = Dts.Variables["User::ExcelFileName"].Value.ToString() +" "+ String.Format("{0:M-d-yyyy}", endDate);
string ExcelFileName = Dts.Variables["User::NewExcelFileName"].Value.ToString();
string FolderPath = Dts.Variables["User::FolderPath"].Value.ToString();
string StoredProcedureName = Dts.Variables["User::StoredProcedureName"].Value.ToString();
string SheetName = Dts.Variables["User::SheetName"].Value.ToString();
string connStringDB = "MyConnString";
string excelConn = String.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0}{1};Mode=ReadWrite;Extended Properties='Excel 12.0 Xml;HDR=YES';", FolderPath, ExcelFileName);
using (var conn = new SqlConnection(connStringDB))
using (var command = new SqlCommand(StoredProcedureName, conn)
{
CommandType = CommandType.StoredProcedure
})
{
conn.Open();
string queryString = String.Format("EXEC {0}", StoredProcedureName);
SqlDataAdapter adapter = new SqlDataAdapter(queryString, conn);
DataSet ds = new DataSet();
adapter.Fill(ds);
//Get Header Columns
string TableColumns = "";
// Get the Column List from Data Table so can create Excel Sheet with Header
foreach (DataTable table in ds.Tables)
{
foreach (DataColumn column in table.Columns)
{
TableColumns += column + "],[";
}
}
conn.Close();
// Replace most right comma from Columnlist
//TableColumns = ("[" + TableColumns.Replace(",", " Text,").TrimEnd(','));
TableColumns = ("[" + TableColumns.Replace(",", " text,").TrimEnd(','));
TableColumns = TableColumns.Remove(TableColumns.Length - 2);
//Use OLE DB Connection and Create Excel Sheet
using (OleDbConnection connODB = new OleDbConnection(excelConn))
{
connODB.Open();
OleDbCommand cmd = new OleDbCommand();
cmd.Connection = connODB;
cmd.CommandTimeout = 500; //Entered by Oleg
cmd.CommandText = String.Format("Create table {0} ({1})", SheetName, TableColumns);
cmd.ExecuteNonQuery();
foreach (DataTable table in ds.Tables)
{
String sqlCommandInsert = "";
String sqlCommandValue = "";
foreach (DataColumn dataColumn in table.Columns)
{
sqlCommandValue += dataColumn + "],[";
}
sqlCommandValue = "[" + sqlCommandValue.TrimEnd(',');
sqlCommandValue = sqlCommandValue.Remove(sqlCommandValue.Length - 2);
sqlCommandInsert = String.Format("INSERT INTO {0} ({1}) VALUES (", SheetName, sqlCommandValue);
int columnCount = table.Columns.Count;
foreach (DataRow row in table.Rows)
{
string columnvalues = "";
for (int i = 0; i < columnCount; i++)
{
int index = table.Rows.IndexOf(row);
var a = table.Rows[index].ItemArray[i].ToString().Replace("'", "''");
columnvalues += "'" + a + "',";
//columnvalues += "'" + table.Rows[index].ItemArray[i] + "',";
}
columnvalues = columnvalues.TrimEnd(',');
var command2 = sqlCommandInsert + columnvalues + ")";
cmd.CommandText = command2;
cmd.ExecuteNonQuery();
}
}
conn.Close();
}
}
Dts.TaskResult = (int)ScriptResults.Success;
}
catch (Exception exception)

using (StreamWriter sw = System.IO.File.CreateText(Dts.Variables["User::FolderPath"].Value.ToString() + "\\" +
