C# Ado.net Sql query parameter query
I'm trying to pass in a parameter value from an array in a loop that is used in a sql query and the results are populated to an xml file. The trouble is that I'm only getting the colums values in the outputted xml file. So I feel that the paramter is not being read.
So can anyone help as I'm really stuck on this one. The code is as follows :
public void DisplayUserInfo()
ArrayList UserIdArrayList = IdentifyUserID();
foreach(string ShowUserIDString in UserIdArrayList)
SqlConnection SqlConn = new SqlConnection(DBConnString)...Parameter query

There is a generic answer to your question: Yes, there is a construct
called a sub-query that allows you, in 1 SQL statement, to query from a

I'm working on converting an Access DB that I created into an ASP.NET application (and attempting to learn ASP at the same time...). One of my queries was very complex and required running a different query first, and then working off of that one. Any suggestions on the best way to do this in ASP?

I am trying to use values from query as keys for another query. I have
one main form with tabforms on it. On the main form I have a main query,
query_1. On the tabform I have a query, query_2.
Each record in query_1 will have multiple corresponding records in
query_2. Each time I move the cursor in query_1 I want query_2 to
re-execute and produce a new recordset. I will do this by passing values
from query_1 to query_2 as parameters. I can get the values from query_1
but I am having trouble getting query_2 to execute with the parameters.

I have found a problem with the customizable queries.
In the function SaveQuery in the file AccessDataAccessLayer.cs, there is a foreach loop to go through each query clause and add them in the database.
However, if for example I create a query with two clauses, the boolean operator for the second clause will be the same of the one for the first clause. It seems that the new value is not set properly in the parameter.
Also, the length of the fieldname of the first clause is applied to the fieldname of the second clause and if it is longer, the fieldname is cut, causing an er...Query with parameters
