Getting Exactly 1 Row From Related Table

Jan 5, 2008

I have the following tables

tblUserdata
usercode username firstname lastname
5 peter peter smith
11 john433 john doe
15 simonsays Simon Smith

tblEvents
ID postedbycode title eventtext createdate
1 5 woodstock 'oldies'  12/12/2008
2 11 love parade 'dance all night 1/1/2008
3 11 spring break 'great party' 2/2/2006

tblEventVisitors
usercode eventid
5   1
5   3
11  1
11 2
11 3


As you can see User John433 is going to 3 events.
But I only want to select the one that has the first upcoming startdate bigger than now: getdate()

Desired output would be:
username firstname lastname eventid title eventtext eventdate
peter Peter Smith 1 woodstock 'oldies'  12/12/2008
john433 john doe 2 love parade 'dance all night 1/1/2008
simonsays Simon Smith NULL NULL NULL NULL


How can I make such a selection? (perhaps see this thread for similar info: http://forums.asp.net/t/1201266.aspx)

Thanks!

Newbie-DELETE A Record In A Table A That Is Related To Table B, And Table B Related To Table A

Mar 20, 2008

Hi thanks for looking at my question

Using sqlServer management studio 2005

My Tables are something like this:

--Table 1 "Employee"
CREATE TABLE [MyCompany].[Employee](
[EmployeeGID] [int] IDENTITY(1,1) NOT NULL,
[BranchFID] [int] NOT NULL,
[FirstName] [varchar](50) NOT NULL,
[MiddleName] [varchar](50) NOT NULL,
[LastName] [varchar](50) NOT NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeGID]
)
GO
ALTER TABLE [MyCompany].[Employee]
WITH CHECK ADD CONSTRAINT [FK_Employee_BranchFID]
FOREIGN KEY([BranchFID])
REFERENCES [myCompany].[Branch] ([BranchGID])
GO
ALTER TABLE [MyCompany].[Employee] CHECK CONSTRAINT [FK_Employee_BranchFID]

-- Table 2 "Branch"
CREATE TABLE [Mycompany].[Branch](
[BranchGID] [int] IDENTITY(1,1) NOT NULL,
[BranchName] [varchar](50) NOT NULL,
[City] [varchar](50) NOT NULL,
[ManagerFID] [int] NOT NULL,
CONSTRAINT [PK_Branch] PRIMARY KEY CLUSTERED
(
[BranchGID]
)
GO
ALTER TABLE [MyCompany].[Branch]
WITH CHECK ADD CONSTRAINT [FK_Branch_ManagerFID]
FOREIGN KEY([ManagerFID])
REFERENCES [MyCompany].[Employee] ([EmployeeGID])
GO
ALTER TABLE [MyCompany].[Branch]
CHECK CONSTRAINT [FK_Branch_ManagerFID]

--Foreign IDs = FID
--generated IDs = GID
Then I try a simple single row DELETE

DELETE FROM MyCompany.Employee
WHERE EmployeeGID= 39

Well this might look like a very basic error:
I get this Error after trying to delete something from Table €śEmployee€?


The DELETE statement conflicted with the
REFERENCE constraint "FK_Branch_ManagerFID".
The conflict occurred in database "MyDatabase",
table "myCompany.Branch", column 'ManagerFID'.

Yes what I€™ve been doing is to deactivate the foreign key constraint, in both tables when performing these kinds of operations, same thing if I try to delete a €śBranch€? entry, basically each entry in €śbranch€? and €śEmployee€? is child of each other which makes things more complicated.

My question is, is there a simple way to overcome this obstacle without having to deactivate the foreign key constraints every time or a good way to prevent this from happening in the first place? Is this when I have to use €śON DELETE CASCADE€? or something?

Thanks

Transact SQL :: Delete Records From Table (Table1) Which Has A Foreign Key Column In Related Table (Table2)?

Jun 29, 2015

I need to delete records from a table (Table1) which has a foreign key column in a related table (Table2).

Table1 columns are: table1Id; Name.  Table2 columns include Table2.table1Id which is the foreign key to Table1.

What is the syntax to delete records from Table1 using Table1.Name='some name' and remove any records in Table2 that have Table2.table1Id equal to Table1.table1Id?

Selecting Exactly 1 Row But More Columns From A Related Table..

Jan 4, 2008

I have table 1 from which I select some values belonging to users.In table 2 I store tips a user might give: tipid, tiptitle, tiptext,tipcreatedateA user may give more than one tip.But now I want a query that selects the info of a SINGLE user and the LATEST tip he created, so resultset might look like:username lastname sex tiptitle tiptext tipcreatedateSo even though a user might have given more tips, only the latest will be retreived...and thus 1 row for a particular user is returned...How would I construct such a query? The problem is that I want to get exactly 1 row but more than 1 column from the table 2, so I think I cannot use the SQL Server "TOP" command...

Table Setup: How Two Members Are Related

Dec 9, 2006

Hi all, What I'm trying to do and having a lot of trouble with is pulling how one user is related to another user from my database. I'll explain...

I set up a table called relationships that looks like this:

ID
type: int

RELID1
type: int, is the user id that initiated the relationship request.

RELID2
type: int, is the user id of the second person in the relationship.

Story
type: varchar(255), quick blerb on how they are related.

Type
type: int, a number 1-20 based on the relationship they have

Status
type: int, 1 = confirmed by second person, 0 = not confirmed

What i'd like to have pulled is a list of the people that person (for example: 70) is related to. I am having the two following problems:
1. unqid of "70" could be in RELID1 or RELID2 as they could have initiated the request or been the second person.
2. I don't want to display them selves in their own relationship listing

Example Data:
ID
1
2
3
4

RELID1
25
15
70
12

RELID2
54
70
13
8

Story
Met on the east coast
Met at walmart
Met walking
Met outside

Type
14
11
3
8

Status
1
1
1
1

Example Output:
Again assuming the current user is "70", the sql should pull: 15, 13.. but i'd like to pull their names from another table called "Users" where "15" and "13" are the UnqID's in a column called "ID".
So:
15 = Bob Smith
13 = Jane Doe

The following code works great that I got with the help on another form:


SELECT Relationship.RELID1
, Relationship.RELID2
, ReMembers.FirstName
, ReMembers.LastName
FROM Relationship
INNER
JOIN ReMembers
ON ReMembers.AccountID = Relationship.RELID1
WHERE Relationship.RELID2 = 70
UNION ALL
SELECT Relationship.RELID1
, Relationship.RELID2
, ReMembers.FirstName
, ReMembers.LastName
FROM Relationship
INNER
JOIN ReMembers
ON ReMembers.AccountID = Relationship.RELID2
WHERE Relationship.RELID2 = 70


My question is: What is the best way to set this table up? I'm not committed to any any design as of right now, but want to be sure I set it up in the most efficient manner.

Any feedback / opinions are welcome! :)

Automatic Insert Of Data Into A Related Table

Jul 20, 2006

I have two tables.  When my user completes an insert of data in table (1), I would like the second "related" table (2) to be automatically populated with defaults.  Is this possible?
My logical approach to this is:
1.  Build a handler for the OnInsert event of the first table
2.  In the handler, call the Insert Command on the SQLDataSource for the second table with the defaults specified in the DataSource.
What I'm not sure how to do is Step 2 or whats the best way.  How do I call the Insertcommand programmatically for a DataSource?  Or, is there a better way such as some kind of traditional hardwired SQL insert statement like in classical ASP?  Or is there a way to programmatically call a stored procedure and if so is the 3rd approach the best way?
 
How exactly would someone do this best?  It seems this would be a rather common thing someone might need to do.

Getting And Inserting Logged In Username To Related Table

Nov 18, 2005

Hi,I've got VS 05 web dev express installed and i'm trying the walkthroughs for login admin. I've succeeded and noticed the tables VS05 produces in the database ASPNETDB.MDF. I've created a new table "Customers" also with a UserID and also configured it as "UniqueIdentifyer" as VS05 has done in the table aspnet_users. The Customers table has two other fields: CustID (autoint) and CustomerName. Now i'm setting up a detailsview control that should insert a CustomerName but I also want it to insert the current logged in userID to the Customers.UserID field so that the aspnet_users and customers tables can be related. My question is how would my Sql insert statement look like to incorporate the parameter of the current logged in UserID and insert it into the Customers.UserID field?thanks.

Help With Pulling Data Related To All Items In A Table

Jan 11, 2006

Hey guys,
I have created an asp.net page where users can select multiple items and then submit the form.  I would like to return related items back.  The catch is, I want to only return items that are related to all of the selected items.
I've created a SQL Procedure that puts each of the inputted item's ItemId in to a temp table, I have a second table called RelatedItems which I use as my junction table that has ItemId, and ReleatedItemId, I then have my Item table that has the data I want to get to (I've excluded this because I have no trouble pulling out data once I have an ItemId)
I can pull out all related ItemIds with a simple join, however I don't know where to start when it comes to pulling out only items related to all ItemIds in the @TempTable.
Any help or suggestions would be great.
Thanks,
Matt

Identify Range And Related Data From Look Up Table

Dec 27, 2007

I have a query/report that I need to create that needs to look at the size of a company and based on that size apply different rules. I am sure that this is not the only query/report I'll need to do using this and I'm also not so sure that the size ranges won't be changed in the future. Given this, I'd like to store the size ranges in a lookup(global) table. That way, if the ranges ever change I can just alter them in that table and not in all of the queries/reports that use them. What I need to figure out is how to join the live table with the look up table.

Specifically, here is what I have. The look up table would be:




Code Block
CREATE TABLE #gl_sizerange (
glsid int IDENTITY(1,1) NOT NULL,
lowsize int,
highsize int,
sizecat varchar(10),
milestone varchar(25),
days int
) ON [PRIMARY]
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Approach', 14)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Interview', 14)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Demonstrate', 21)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Negotiate', 14)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Close', 7)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Approach', 14)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Interview', 21)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Demonstrate', 21)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Negotiate', 14)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Close', 7)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Approach', 14)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Interview', 21)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Demonstrate', 21)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Negotiate', 14)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Close', 7)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Approach', 28)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Interview', 35)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Demonstrate', 28)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Negotiate', 35)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Close', 35)




Then what I have is two more tables, one that indicates the size of the company and another that has the milestone contained within it and I will also calculate how long that milestone has been open and if it is longer than what is in the lookup table for that milestone and size range I need it returned in the report. Here are some quick sample table to represent that data (I've condensed the size and number of tables for the example):




Code Block
CREATE TABLE #en_entity (
enid int NOT NULL,
orgsize int,
) ON [PRIMARY]

INSERT into #en_entity VALUES(1, 5)
INSERT into #en_entity VALUES(2, 18)
INSERT into #en_entity VALUES(3, 24)
INSERT into #en_entity VALUES(4, 25)
INSERT into #en_entity VALUES(5, 47)
INSERT into #en_entity VALUES(6, 101)
INSERT into #en_entity VALUES(7, 499)
INSERT into #en_entity VALUES(8, 500)
INSERT into #en_entity VALUES(9, 10000)
INSERT into #en_entity VALUES(10, 567890)
CREATE TABLE #op_opportunity (
opid int NOT NULL,
enid int NOT NULL,
milestone varchar(25),
daysopen int
) ON [PRIMARY]
INSERT into #op_opportunity VALUES(1, 1, 'Approach', 5)
INSERT into #op_opportunity VALUES(2, 2, 'Interview', 18)
INSERT into #op_opportunity VALUES(3, 4, 'Negotiate', 24)
INSERT into #op_opportunity VALUES(4, 7, 'Demonstrate', 25)
INSERT into #op_opportunity VALUES(5, 7, 'Approach', 7)
INSERT into #op_opportunity VALUES(6, 9, 'Close', 35)
INSERT into #op_opportunity VALUES(7, 8, 'Close', 36)






So, given the sample data, I would expect the results to return me the following opids from the #op_opportunity table because they don't comply with what is in the look up table based on milestone, size and days open: 2,3,4,7

One Table From Two Related Tables: Any Transformation Avaiable?

Dec 4, 2007



Hi everyone!
I'm on my way to learn SSIS by myself and it's a little complicated!
I'd like to ask you one thing:


I have two tables at my data source, one is "Clients" and the other one is ClientsAddress. That is, a client can have more than one address. Both tables are related by a one to many relationship and the tables description is:

CLIENTS CLIENTSADDRESS
#PK_Client #PK_Client
other fields.. #ID_address
... other fields



What i intend to do is to obtain one table with approximately 3 fields, each one for a possible client address; something like this:
CLIENTS
PK_Client
ID_Address1
ID_Address2
ID_Address3

My question is what transformation can i use? an how ?

Thanks very much in advance!!

I am not opposed to using CTE, I really like them, but I cannot figure this one out. But I will try most anything.

Is There A Command That Returns Every Constraint Related To A Colonne/table

May 14, 2008

Hi,
Not too long ago I was looking to change a primary key in a table from one column to another, the standard accepted procedure to so procedure to do so (I was told) was:
1) drop primary key constraint from old_key_column
2)add primary key constraint to new_key_column
3) drop old_key_column (optional).

In order to carry out the first step, I needed the name of the primary key constraint, at which point I asked around for a command that would return that name (and would quite probably take as a parameter the name of the column that key is related to). The answer was :

Try this:
select name 'constraintName' from sys.indexes where object_id=object_id('<tableName>') and is_primary_key=1

Unfortunately this command never worked for me. Probably because I don't have a table sys.indexes in my DB, but I can see a table sysindexes in the system tables folder, then again that table doesn't have an object_id column, but it has an id column, finally this column only contain obscur numbers.

So I am asking you all (again) for help, do you know about a command that returns every single constraint related to a column (or a table, or both).


One more thing, I am running SQL SERVER 2000, I do know that there are graphic ways to do those very operations (in the enterprise manager or the query analyzer) and I do know those ways (that's how i got past the problem mentioned earlier), I just think that knowing how to do it programmatically would be a plus.

PS: I am a total newbie to T-SQL (and a still a beginner in SQL, so please take it easy with me )

Nested SELECT Query That Also Returns COUNT From Related Table

Mar 4, 2005

OK heres the situation, I have a Categories table and a Products table, each Category can have one or many Products, but a product can only belong to one Category hence one-to-many relationship.

Now I want to do a SELECT query that outputs all of the Categories onto an ASP page, but also displays how many Products are in each category eg.

CatID | Name | Description | No. Products

0001 | Cars | Blah blah blah | 5

etc etc

At the moment I'm doing nesting in my application logic so that for each category that is displayed, another query is run that returns the number of products for that particular category. It works ok!

However, is there a way to write a SQL Statement that returns all the Categories AND number products from just the one SELECT statement, rather than with the method I'm using outlined above? The reason I'm asking is that I want to be able to order by the number of products for each category and my method doesn't allow me to do this.

Many thanks!

T-SQL (SS2K8) :: Delete All Rows Satisfying Certain Condition From Table A And Related Records From B And C

Apr 14, 2015

I have around 3 tables having around 20 to 30gb of data. My table A related to table B by a FK and same way table B related to table C by FK. I would like to delete all rows satisfying certain condition from table A and all corresponding related records from table B and C. I have created a query to delete the grandchild first, followed by child table and finally parent. I have used inner join in my delete query. As you all know, inner join delete operations, are going to be extremely resource Intensive especially on bigger tables.

What is the best approach to delete all these rows? There are many constraints, triggers on these tables. Also, there might be some FK relations to other tables as well.

Need Help Related To MDX Please

Nov 23, 2004

Hi,

Is there a format function in MDX which will help me solve the following
scenario:

One of my measures is Net Sales and I have tried all different formats
in Analysis Services so that it shows without the decimal places i.e.
instead of showing the Net Sales for any selected combination of
Dimensions as 123,456.04, I want to show it as 123,456

When I browse the cube (in Analysis Services), I can meet my
requirement. However, in my front-end (Microsoft Data Analyzer), I am
still getting it as 123,456.04 (even when the same in Analysis services,
i.e. when I browse the cube, is being shown as 123,456).

I do not have much choice at the moment and am stuck with Microsoft Data
Analyzer and unfortunately have not been able to solve this :(

Can someone think of a solution/workaround/use of MDX which will help me
get the results being displayed without the decimal. Is there a format function that I can use in MDX and how to use it???

Many TIA

This Seems Messy To Me... [OOP-related]

Nov 20, 2006

I've been working on a performance review web application (i.e., employee's annual reviews done via the web). In the process of creating the application I've been teaching myself .NET - maybe not the best way to do it but I've been learning a lot. However, I still feel like I'm not doing something right.On each Page_Load I'm doing database work with a data reader: Reading the data in, displaying it, letting the user add, edit, or delete it, etc. So every Page_Load code behind looks like this: string sql = "SELECT UserID, Passwd, RecID, Name FROM UserList";

SqlConnection myConn = new SqlConnection("Server=BART; Database=WSSD; User ID=sa; Password=wss1231");
SqlCommand cmd = new SqlCommand(sql, myConn);
SqlDataReader dr;

myConn.Open();
dr = cmd.ExecuteReader(); And so forth and so on. Now since I re-use this code again and again - I imagine it's a good idea to implement my connection code in a class that I can re-use easily. But I have no idea where to start on something like that. What can I say? I'm a newb. A push in the right direction would be great.

DTS Related Question

Mar 10, 2005

Hi,

I made a DTS which appends data coming infrom a view to an exisiting table.So far no problem and all goes well.

I am facing a problem due to the format of the date that is coming in (getting appended) and while going through BOL, came across the following topic:

mk:@MSITStore:C:Program%20FilesMicrosoft%20SQL%2 0Server80ToolsBookshowtosql.chm::/ht_dts_trns_97ou.htm

I tired the above tips but it appears that if I try to do this in my DTS (which appends data),the logic of the DTS will change. A single arrow also gets added whichI think represents a simple mapping/transformation rather than a append. To clarify my point, please note the attached image which represents that the data is being appended (due to the many sided arrows pointing to the source and destination - visible under the Transformations tab of my DTS).

Sincerely hoping that my post is clear, can someone help me find how to make changes in a DTS (which appends data) and ensuring that thelogic remains the same i.e. it should append data.
