How to Run two Update Sql Queries using this Sql Snippet ?
The code mentioned below is updating values only in one table .... i want to update data in two different tables using the code mentioned below :
can anybody reedit this code ?
Try
Using conn = New SqlConnection(constr)
Using cmd = conn.CreateCommand()
conn.Open()
Dim sql As String =
"UPDATE a1_ticket
SET Ticket_no =#ticketNo,
BANK = #bank,
PAID = #paid,
BID = #bid
WHERE ITC = #ticketNo"
cmd.CommandText = sql
cmd.Parameters.AddWithValue("#bank", Literal20.Text)
cmd.Parameters.AddWithValue("#paid", Label1.Text)
cmd.Parameters.AddWithValue("#bid", Literal21.Text)
cmd.Parameters.AddWithValue("#ticketNo", Literal3.Text)
cmd.ExecuteNonQuery()
End Using
End Using
Catch ex As Exception
Response.Write(ex.Message)
End Try

Answer 1

Create a Stored Procedure that updates the two tables and execute it using a StoredProcedure Command...
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "UpdateTheTwoTables";
....

Answer 2

Modify the SQL statement to update the two tables.

Answer 3

Using a Stored Procedure is the cleanest way code wise. If you don't feel comfortable doing it like that, I'm sure you can do it like this:
Try
Using conn = New SqlConnection(constr)
Using cmd = conn.CreateCommand()
conn.Open()
Dim sql As String = "UPDATE a1_ticket SET Ticket_no =#ticketNo, BANK = #bank, PAID = #paid, BID = #bid WHERE ITC = #ticketNo"
cmd.CommandText = sql
cmd.Parameters.AddWithValue("#bank", Literal20.Text)
cmd.Parameters.AddWithValue("#paid", Label1.Text)
cmd.Parameters.AddWithValue("#bid", Literal21.Text)
cmd.Parameters.AddWithValue("#ticketNo", Literal3.Text)
cmd.ExecuteNonQuery()
End Using
//
Using cmd = conn.CreateCommand()
conn.Open()
Dim sql As String = "UPDATE a2_ticket SET Ticket_no =#ticketNo, BANK = #bank, PAID = #paid, BID = #bid WHERE ITC = #ticketNo"
cmd.CommandText = sql
cmd.Parameters.AddWithValue("#bank", Literal20.Text)
cmd.Parameters.AddWithValue("#paid", Label1.Text)
cmd.Parameters.AddWithValue("#bid", Literal21.Text)
cmd.Parameters.AddWithValue("#ticketNo", Literal3.Text)
cmd.ExecuteNonQuery()
End Using
End Using
Catch ex As Exception
Response.Write(ex.Message)
End Try
It's a sketch of what I'm trying to say, you may want to change a few things here and there, but the point is you can just update your two tables one after the other. It's not possible in one update statement afaik.

Answer 4

you can also use
Dim sql As String = # "Query for first update;
Query for second update;";

Answer 5

Well as you havent said anything about the second table, or the data you're sending it. I havent put this through the compiler to verify it, but the concept I'd suggest would be
You could do:
void UpdateDB(String sql, String[][] params)
{
Try
{
SqlConnection conn = New SqlConnection(constr);
SqlCommand cmd = conn.CreateCommand();
conn.Open();
cmd.CommandText = sql;
for(int i=0; i<params.length; i++)
{
cmd.Parameters.AddWithValue(params[i,0] params[i,1]);
}
cmd.ExecuteNonQuery();
}
Catch (Exception ex)
{
Response.Write(ex.Message);
}
}
eg send the SQL and the parameters to the function and have it do all the work..
