Mi am creating a program in vb.net and was wondering if there is a way to perform multiple queries with one button without adding a second button.like i have two text boxes, one is for date and the other is for name. what i want to do is if i hit search and both the date and name boxes are filled, i want it to search for the name based on that date. but if only the name is filled i want to search for everything under that name

I am trying to perform a search query using drop down boxes with a button named search. I want it to bring up the data that is searched for. I dont know where to start from, i have looked around for some coding and different ways to do it but they seem complicated, this is the bit of ASP that is my weakness, need some assistance and guidance. below is the code for the page;

I'm building an application that will be using several (7) SQL queries, I'm wondering whats the best way to approach this since I've never built an app with this many queries in it. These queries really won't change, just the start date and end date and I have query in my first form that finds out the next available date by checking a table. What I'm wondering is if it would be better to construct these queries in my application or if it would be better to use stored procedures on my sql server to do the same thing and not have the application carry the load of the queries.

My project contains a DataGridView with a SQL Database Table called Shows. This is a list of TV Shows and I want to apply several filters to it. So I have several different columns to apply the filter to.
1. Completed (bit)
2. Hide (bit)
3. Seen (bit)
4. Genre (nvarchar)
Currently I am using RadioButtons to switch between the queries, but I want to be able to have several filters applied at the same time with CheckBoxes.

In .NET, Is it possible to run a nested query from two separate Oracle databases?

Ultimately, this is an effort to overcome an "ORA-01795" error from using an "in" statement with over 1000 items in the conditional list, without having to break the query out into multiple "OR value IN" lists.
I am trying to fill a temporary table with one column( a code) with the unique results of three queries of their respective table adapters.I can't figure out how to do it from here.The database is Access 2007 and I have activated the appropriate dataset on the form from which this code executes. The table adapters are part of that dataset.I could try to use the recordset approach, but that means making another connection to the same database.Is that a preferable approach?My purpose in doing this is to build a VB process like the one that works in a VBA Module of this Accessdatabase, partly to help me learn VB2008 and partly to overcome the necessity to keep updating queries used by the module.Code below

I need to loop through a gridview to find records that match items in a different table (in SQL). Is the best method to loop through the gridview and call an SQL procedure on every loop to find matching records? Or should I pull the entire sql db into a datatable and query the dataset in my gridview loop?

Dim cSource As New clsSource()
Dim ds As DataSet = cSource.GetSources()

There is not a VB.net database forum, and there is a HUGE difference (unfortunately) between ADO and ADO.net. I have a connection to a MS SQL database, which I understand is capable of handling multiple SQL statements in one Execution, ie
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=123;Insert into mytable (UniqueID, Field) values (123, 'something')"
.CommandText = strSingleSQLLine

There are two questions here actually...can I add the parameters before setting the command text, and do I have to add the same parameter over and over again?

View 1 RepliesWe use an ERP program in conjuction with SQL server and lots of tables that keep track of product records customers and all these kinds of stuff. I am building a fairly simple Warehouse Inventory Application that warehouse employees will use to count and inventory stock on hand from products around the warehouse and then check if any quantity errors occur between stock on hand and logistic quantities.I have created a custom Inventory table that I would populate with records like {stock_code, Description, Quantity_remain, quantity_avail}. Those records already exist in 2 different tables in my database. The aim is that I want my program to fetch daily 10 random codes from the stck table, and records about their quantities,bringing together the "columns" that my new custom table has +2 more editable columns: inventory, date, user with a query like this:[code]
As you can imagine my custom table contains the exact same fields as the query suggests + 3 more.I use the the stck table to fetch product info like its code,description, its group_code, categ_code, and then I outer join the stck_x_th that contains records concerning quantities remaining or available asociated with each product code and the "places" those quantities reside in the warehouse.Then, store them in a datagridview control, with only one editable column -inventory- (user and date columns are auto-populated with default values), and then when the user fills out the inventory quantites, I want to save the datagrid "as it is" in my new custom table.I am creating a databound gridview control using one table adapter (which refers to the inventory table). Then I add to my table adapter using "add query" the forementioned query with a fillby method to populate the Datagrid (and therefore my Table in SQL) with the exact same values my query returned from the different tables. But whenever I try to update the table concurrency exceptions raise.It works like a charm if I enter the values in the grid cells manually, without populating the grid control with the new fillby method my self but not if I populate the grid via a query and then hit update.
changing the way the site search is done from just search a phrase as one string to searching a phrase "as multiple words" search. For example, if I search "cute puppy" right now, it will search it for "cute puppy" as phrase and won't match just "cute" and "puppy". The way the search is implemented is by passing a search phrase to a Stored Procedure in SQL Server.So now, I need to change to site search so when "cute puppy" is searched, it will search two words.... "cute" and "puppy" instead of just "cute puppy". Below is how the store procedure is implemented
SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

Im making a search function for an application and they need to be able to search by any value in the DB in any of the three tables. Im wondering the best wayto about this. 2 of the 3 tables have the same columns while the last one is totally different. Below is what I kinda "thought" itd look like but no.
"SELECT * FROM cases, opencases, staff WHERE Crime ='" & txtsearch.Text.ToString & "'"
I need to query the results the user can search for anyterm and if it matches something in the columns it return it to the user. Im wondering if the best way to go about this is to maybe query all the tables and then put all the matching records in a seperate table and the dgv look at that table or how to exactly go about it.
i'm new at vb.net (though i have extensive vb6 experience and oracle experience), and i need a sample program/project which uses multiple queries (of the same oracle database namespace) to display counts in text boxes.user will use a pull down list to select action from there.

View 3 RepliesI am a new to programming, trying to learn vb.net, so I apologize if my questions are very elementary or my terminology is incorrect. I am trying to format a query to an Oracle table based on user-selected radio buttons on a Windows form (i.e. the query will return different elements from the table based on the radio buttons selected). The query results will be placed in a listbox on the form. My thought was to make a Property containing my query like so:

and then I have a sub that feeds this SQL property (containing the query) into an OracleConnection.My problem is that I don't know how to customize that query depending on what radio buttons are selected by the user. Is a Property the best way to go about this, or is there some other way that may be better?

View 2 RepliesEvery table I have has an 'UpdatedBy' field which lists the user who last made an update to the record. I need a way of searching every datatable for that username and returning the count of the rows where the LastUpdated field is equal to a parameterized username. How can this be accomplished without writing a seperate query for each datatable that does the same thing and running each query one at a time? I'm not sure if this can accomplished somehow in the dataset itself or if a SQL Function could do this.
