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.

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'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 am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?

I am creating an album using the following stored procedure, which returns the primary key for the newly created record:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[fpa_sp_albums_update_insert]
@album_id int,
@album_name nvarchar (50),
@album_descr nvarchar(250),
@album_img_cover_id_FK int,
@album_creation_date date
AS
If @album_id > 0
UPDATE [fpa_albums]
SET
album_name=@album_name,
album_descr= @album_descr,
album_img_cover_id_FK = @album_img_cover_id_FK,
album_creation_date = @album_creation_date
Where ((album_id = @album_id))
Else
INSERT INTO [fpa_albums] (
album_name,
album_descr,
album_img_cover_id_FK,
album_creation_date)
VALUES (
@album_name,
@album_descr,
@album_img_cover_id_FK,
@album_creation_date)
Return SCOPE_IDENTITY();
I execute the above stored procedure using the SQLHELPER. The VB.NET code for the page is as follows:

However, the createdAlbumID always shows -1 instead of the id for the newly created album.

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'

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.

I am writing a simple form that will take in data and insert it into a db if it's a new record and update the existing record if it already exists. The insert works fine, but the update isn't working at all, yet the code looks solid to me and everything I've compared it to in my google searches.

I've done some SSIS package work in the past, but am by no means an expert.
I want to use an SSIS package to do the following:
1. Get the file name of the newest file in a windows folder (using a filename template like his: filename_ *.txt where the * part is always a date in the format of yyyy-mm-dd.
2. Use that file name in later portions of the SSIS package by reading the file and transferring data from it to a SQL table using a Data Flow task.
and use the result (which should be the name of the newest file) to open that file and pull data out of it and into a 2nd SQL table. I admit, I'm not sure how to use the dynamic result of this SELECT query as the file name in a flat file connection manager.

I am currently trying to create a SQL statement that does a multiple count on a table. The table has a number of reports each listing the "User" who created that report and if that report is "Famous" (A famous report is symbolised as 2 in the table).
What I need to create is a SQL statement that returns each User with the total number of reports he/she has created and how many of these reports are famous. My current SQL statement looks like:
