How to extend the timeout of a SQL query

Question

This is not a connection timeout as a connection to the database is made fine. The problem is that the stored procedure that I\'m calling takes longer than, say, 30 seconds and

Answer 1

Timeout can occur due to a Microsoft issue. Seems to still occur on my Windows 8 system.

Answer 2

I think this might be a better way to do this (as of Enterprise Library 6.0):

SqlDatabase db = new SqlDatabase(connectionManager.SqlConnection.ConnectionString);
System.Data.Common.DbCommand cmd = db.GetStoredProcCommand(storedProc, parameterValues);
cmd.CommandTimeout = 600;
return db.ExecuteScalar(cmd);

Answer 3

Mladen is right but if you have to do this you probably have a bigger problem with the proc itself. Under load it might take much longer than your new timeout. Might be worth spending some quality time with the proc to optimize.

Answer 4

Try this one

SqlConnectionStringBuilder connectionStringBuilder = new SqlConnectionStringBuilder(connection.ConnectionString);
connectionStringBuilder.ConnectTimeout = 180;
connection.ConnectionString = connectionStringBuilder.ConnectionString;

connection.Open();
SqlCommand command = new SqlCommand("sp_ProcedureName", connection);
command.CommandType = CommandType.StoredProcedure;
command.CommandTimeout = connection.ConnectionTimeout;
command.ExecuteNonQuery();
connection.Close();

If you are using the EnterpriseLibrary (and it looks like you are) try this:

 Microsoft.Practices.EnterpriseLibrary.Data.Database db = Microsoft.Practices.EnterpriseLibrary.Data.DatabaseFactory.CreateDatabase("ConnectionString");
 System.Data.Common.DbCommand cmd = db.GetStoredProcCommand("StoredProcedureName");
 cmd.CommandTimeout = 600;
 db.AddInParameter(cmd, "ParameterName", DbType.String, "Value");

 // Added to handle paramValues array conversion
 foreach (System.Data.SqlClient.SqlParameter param in parameterValues) 
 {
     db.AddInParameter(cmd, param.ParameterName, param.SqlDbType, param.Value);
 }

 return cmd.ExecuteScalar();

Edited to handle the paramValues array directly based on the comments. I also included your ConnectionString value:

Microsoft.Practices.EnterpriseLibrary.Data.Database db = Microsoft.Practices.EnterpriseLibrary.Data.DatabaseFactory.CreateDatabase(connectionManager.SqlConnection.ConnectionString);
System.Data.Common.DbCommand cmd = db.GetStoredProcCommand("StoredProcedureName", parameterValues);
cmd.CommandTimeout = 600;
return cmd.ExecuteScalar();

Answer 6

you do this by setting the SqlCommand.CommandTimeout property
