This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords
FROM (Merchandise)
WHERE Keywords LIKE @term
The only other thing I can think of the gain this level of functionality would be to combine them into a new table.

I have 2 tables with UserId and FirstName, LastName Columns that I want to combine the data in a Select Statement or Stored Procedure
1. The 2 tables will never have the same data, each table will be distinct
2. I want to combine first and lastnames to a full name (t1.FirstName + ' ' + t1.LastName) AS FullName
3. The statement will be used to populate a dropdownlist with UserId as Value, and Name as text
I am unsure how to accomplish this since I do not need to connect the tables, but combine the Sum of their data.

I don't know if I'm posting this in the right place - I have a feeling it can't be too difficult but I can't seem to figure it out. I've come across this problem many times and I've never solved it. I would imagine the scenario is commonplace - I have a table of Products with a PK of ProductID, and a table of related images with a FK of ProductID. Each product can have many images, but for my initial display I want to display one product record with one image record. I have a Sequence field in the Images table and I could pick the lowest one. Right and left Joins return too many records - if I have three images for Product 1 then Product 1 is listed three times.
I've gotten around this before using a flag in the Products table, or listing an image in both tables but I'm sure there must be a SQL statement that can get the information that I need.

I've got 3 tables.
Table A: UID, Name
Table B: CID, Category
Table C: ID, UID, CID
I've got a TextBox to capture the value of "Name" in Table A.
Ive got a CheckBoxList that displays all the pre-determined values of Table B.
When the user selects an item from the CheckBoxList i want to populate Table C with the value of the selected item from the CheckBoxList and the cooresponding ID associated with the user name for that person's entry.
How do I write the INSERT statement?

I am trying to count records belonging to a certain person in three different tables in a single select statement. The database looks like this:
Player
-PlayerId
-Name
Game
-GameId
-TournamentId
...
Goal
-GameId (FK->Game.GameId)
-PlayerId (FK->Player.PlayerId)
-Assist (FK->Player.PlayerId)
Card
-CardId
-GameId (FK->Game.GameId)
-PlayerId(FK->Player.PlayerId)
I want to select the number of goals, assist and cards a player has in a specific tournament. I tried with this query but then the goal and card column shows the sum of the number of rows matching the playerid in the Goal table and the Card table...For example if there is two matching rows in the goal table and three matching rows in the card table, I get 5 in both these columns in the resultset.

I have the following simple stored procedure:
ALTER PROCEDURE GetadiByPhiNo
@PhiNo int
SELECT adirefno, adidescription
FROM aditable
WHERE adiphino = @PhiNo
Here is an example of data returned:
1 Skin diesease
2 Cough
3 Cough
4 Rash
You notice "Cough" is in the adidescription column twice. I would like to return only one row for adidescription with the same value. So what I want returned is this:
1 Skin diesease
2 Cough
4 Rash

I'm facing a problem in our current running application. There is a table in database which has 67 columns,among these 18 columns are nvarchar(max) datatype and contains 30K records. Problem is now that SELECT * FROM myTable it takes around 3 to 4 seconds. Which is degrading our application's performance.

I need to join some tables to get the matching records. I often have to ask around to see how certain tables could be joined. Is there any way to query the information schema or some thing else to see what columns/values match in certain tables in order to figure out how tables should be joined.

Dim AlterTable As String = "alter table [Upload] add [Country] nvarchar (50) default 0 NOT NULL,[Address] int default 0 NOT NULL"
Dim connection As Data.SqlClient.SqlConnection
connection = New Data.SqlClient.SqlConnection()
connection.ConnectionString = ConfigurationManager.ConnectionStrings("ASPNETDBconnectionString1").ConnectionString
Dim cmdUpdating1 As New Data.SqlClient.SqlCommand(AlterTable, connection)
cmdUpdating1.CommandType = CommandType.Text
connection.Open()
cmdUpdating1.ExecuteNonQuery()
connection.Close()
This is the code which I am using for altering the number of columns in a table in the DB. so with this code i am able to add new coulmns dynamically. Now my major requirement in this is to obtain the headercount from the user( say "telephone number" and "language") and based on it generate the columns dynamically in the table in the DB.

I am trying to create an application in which there is a summary of outstanding payments.
One table is Table_Bills.
The other table stores records of Payments made and is called Table_Payments.
In summary i want to show 3 figures - each in separate one field datagridview with a data_source in separate data_adapter:
1) Ammount_Due 2) Amount_Paid 3) Balance.
The first two are no problem but the last is giving me a headache.
I tried this:
SELECT SUM(DHB_New_Jobtable.DayWage) - SUM(DHB_Payments.Ammount) AS Expr1

I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

based on this LinQ code:

I also have taken account to Int32 due to entity framework http://msdn.microsoft.com/en-us/library/bb896317.aspx. Unfortunatley, still same problem.

I'm fairly new to all this, but have slowly been teaching myself C# and ASP.net MVC over the past year or so...I really tried to search for this, but haven't been able to find anything - it may be I'm using the wrong terminology!I'm using ASP.NET MVC2 with EF4 connected to a SQL Express db. Situation: Without getting into too much specifics, I have one table called 'Plan.' Under 'Plan' are several different categories that are related to a single Plan item [say Category A, Category B, Category C and Category D]. Each 'Category X' table has a beginDate, endDate and other details specific to that category.
I'd like to be able to create a summary page that combines all items from Category A, Category B, Category C, and Category D and sorts by beginDate - but only need a few of the columns [eg - begin/end date, name, id].

I have a dataset like this:
BidID....DistributionMonth....LbsRemaining
1...........08-2010.................50,000
1........... 09-2010................25,000
1............10-2010................25,000
1............11-2010................100,000
I have a report that shows this data by pivoting on the month and giving the remaining amount, like this:
BID......Aug-2010 Remaining........Sep-2010 Remaining.......Oct-2010 Remaining........Nov-2010 Remaining
1..........50,000...............................25,000...........................25,000..............................100,000
This all works just fine. However now, I want to take a date that's given, and make a "Past Due" column for anything less than the first of the month of that date.

The case is: I use a webservice that gives me information about companys. For example: I entered a companyname and the webservice give me a list of al company's in the country. The webservices return a one dimensional array. The problem is that I must search in two register so the webservices returns 2 array's. I put the data from both arrays into 2 datatables. The data in the 2 datatables can be different or the same.
The question is: How could I matching the data on ID and combine the data into 1 datatable.
The code:
//Create result
SearchResult Result1;
SearchResult resultZoekmogelijkheid2;
//send van Soap Request

I have a table that contains a date column along with others. I need to extract two sets of data from this table for two different time periods. Call them Current and Previous, so that I can compare them line for line. There are exactly the same number of days in both time periods.
The problem is that I need to return the data like this:
CurrentDate, Count(CurrentItems), Sum(Amt), Count(PreviousItems), Sum(PrevAmt)
JOIN puts the data into the result vertically, so that doesn't work. So far, I have not found a method that will arrange the data correctly.
