I've got 3 tables.

Table A: UID, Name
Table B: CID, Category
Table C: ID, UID, CID

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?

DataSource Controls :: Sql Statement To Get One Record Each From Two Tables?

Feb 2, 2010

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.

DataSource Controls :: Count From Several Tables In One Select Statement

Mar 14, 2010

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:



-GameId (FK->Game.GameId)
-PlayerId (FK->Player.PlayerId)
-Assist (FK->Player.PlayerId)

-GameId (FK->Game.GameId)

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.

SQL Server :: Select Statement For Multiple Tables

Oct 1, 2010

SELECT u.Email FROM UserProfiles p, aspnet_Membership u WHERE p.RulesCheckBox = 'True' AND u.UserId = p.UserId This gives me a list of registered member email addresses that have selected the RulesCheckBox in their profile, so I can email them with an email script. There is a relationship between the Membership table and the UserProfile table, so it finds the email addresses from the Membership table where that user has the RulesCheckBox checked in their profile (in UserProfiles table). I'm wanting to add some additional names to this list, from a different table. The purpose is so I can manually add email addresses to the additional table, so the additional email addresses will also receive the same email, even though they aren't registered members of the site. So how can I adjust that SELECT statement so this one is combined with it somehow?:

SELECT Email FROM ExtraEmails WHERE Rules = 'true'

SQL Server :: Selecting Data From Multiple Tables Whilst Using A Union Statement?

Nov 29, 2010

I basically have a series of tables from one database that have an identical structure thus making retrieval of all records fairly easy (I just use a UNION ALL statement). However I need a list of values from another table within a different database that contains information regarding the group of the data.

I so far have the following:

SELECT Table1.* FROM Table1 UNION ALL SELECT Table2.* FROM Table2 UNION ALL SELECT Table3.* FROM Table3 UNION SELECT Database.dbo.SRFILE.SR_GROUP FROM Database.dbo.SRFILE INNER JOIN Database.dbo.SRFILE.SRONUMBER = Table1.Incidentx

I keep receiving a unable to parse message however all I need to retreive is the SR_GROUP value but just don't know the correct syntax. Is it actually possible to do this as the structure of SRFILE is not the same as Table1/2/3.

DataSource Controls :: Select Statement Pulling Multiple Times From Same Row

Jan 5, 2010


I have a select statement that is supposed to be filling grid with information from an income table. It's only supposed to pull if the income is from the current fiscal year or is less than 1 year old. Currently, what it does is pull multiples of rows and also rows from past income years but only if there is a mixture. For instance, if a person has income from 2005 and 2010 what it will show is this

Income 2005
Income 2005
Income 2010
Income 2010
Income 2010

Does anyone know what I've done wrong? BTW, those results are exact, old income is shown twice, current is shown 3X

DataSource Controls :: Combine Multiple Columns Into One For Select Statement?

May 14, 2010

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 hard time trying to find the solution to retrieve data from multiple tables in one database.

Kategorije.idKategorijais joined with Clanak.idKategorija, but that isn't the solution because I want my web site to show the Kategorije.naziv instead of Kategorije.idKategorija. This is the code I'm currently using to get idKategorije shown on my web site:

DataSource Controls :: Filtering Data Based On Multiple Tables?

Mar 16, 2010

I am writting a directory website that advertises fitness classes. These classes are listed by Class Type, and Geographical Area. Each Class Type can satisfy one or more of four Fitness Goals such as Loose Weight etc...

I have a table for Classes (classid, classname, classdesc, classtypeid, geoareaid) I have a table for geographic areas (geoareaid, geoarea) And I have a table for ClassTypes (classtypeid, classtypename, classtypedesc)

Which obviously links geographic area via the classes.geoareaid as a forgien key and classtypes by classes.classtypeid as a forgien key.

I can list all classes by type and also by geo area no problem, the problem arrises when I then also want to filter by goal.

The Goals Table (goalid, goal, goaldesc) is linked to the classtypes table via another table classtypes_goals (classtypeid, goalid) as each classtype can satisfy any of the 4 goals.

I am using a DataSet to fetch the data from a Stored Procedure in the SQL Database but because the classtypes can be linked to multiple goals I am getting duplication in my list depending on how many goals a classtype satisfies.

All I need in my data list is class name, class type and area I don't even need to display the goal I just want a drop down above the table that will filter the list and show only classes of classtype that satisfy the goal chosen.

DataSource Controls :: Will Multiple Tables In A DataSet Affect Performance

Apr 29, 2010

I have a dataset that comprises of multiple tables (about 20) linked together with constraints to reflect the relational database. My question(s):

1) Will having multiple tables affect performance? I'm asking this as there are often times I would not need to get data for all the tables, but only for specific tables.

2) If it does affect performance, would breaking up the tables into their own datasets be the best solution. It seems to me that by doing that, you would lose the ability to apply constraints among tables and tables that might exist in multiple datasets will be subjected to replication.

I would like to have everything in one dataset as I get a view of the related tables and their relationships and also because the Fill method allow me to fill tables, maintaining the hierarchy of the data, but performance is still a key factor.

DataSource Controls :: Deleting Data From The Multiple SQL Tables With LINQ (C#)?

Apr 22, 2010

I'm looking for ideas on deleting data from the multiple SQL tables with LINQ (C#).

My existing solution does the following:

1. DeleteAllOnSubmit( Subset of the data from the child table)

2. DeleteAllOnSubmit( Subset of the data from another child table)

3. DeleteAllOnSubmit( Data from the parent table)

4. CommitChanges()

All this resides within a single method, which makes it ugly and not re-usable.

I have considered the following alternatives, but I decided not to use them:

1. Cascade delete on the tables.

2. Do a join on all tables from which I will remove the data, but I'm not sure yet whether I could pass a join query to DeleteAllOnSubmit().

3. Write stored procedure(s) to delete data from each table. I don't have the time to implement this due to a large number of tables and the time constraints.
