Creating (almost) Duplicate Rows
Aug 6, 2004Hi everyone, I'm migrating some information for a client at the moment. They had everything in Excel files and I'm getting them into SQL Server. There are some differences in the way I am storing data and the way they were storing data.
For each client they stored, they had something like
Rel1 Rel2 Rel3
100 101 102
Now, what I have is a seperate row for each of Rel1, Rel2 and Rel3 so I would have 3 seperate rows with identical information except for Rel1. So I would have:
Rel1
100
101
102
So one way I thought of doing it was inserting a new row specifying that the value for Rel2 should be stored in Rel1 and for the next row that the value for Rel3 should be stored in Rel1.
Now, I am able to do this but SQL Server inserts an extra row will the NULL value in Rel1. Does anyone know why this would be happening? I think what it is doing is finding a NULL value in Rel3 after creating the two extra rows and is inserting that NULL. So I think I need to check for NULLs and not allow it to create a new row if, say, Rel3 is NULL.
Any pointers are gladly welcome. (I know it's complicated )

Creating An SQL Connection String And Inserting New Rows.
Jun 15, 2006I am ultra new to this so thanks in advance for any help.
I was trying to create a connection to a database that I created in SQL Express. I am essentially trying to submit three attributes to the existing database from a table that consists of three textboxes and a submit button. I would like all of the code to be in the head of the page (because that is the standard here) so I wanted to know what the connection string should be in Visual Basic 2005 Express to establish a connection on the same machine. I'm not sure about the connection string, but I am also not sure about a lot of the code. Also, the Using clauses seem to give me an error (where should it go?). This is what I have in the head of the page (visual C# by the way). Also, I got this from http://www.csharp-station.com/Tutorials/AdoDotNet/Lesson03.aspx :
Using System.Data;Using System.Data.SqlClient;protected void Button1_Click(object sender, EventArgs e){SqlConnection conn = new SqlConnection("Data Source=(local);Database=CustomersDB;Trusted Connection=true");conn.Open();string insertstring = @" insert into Catagories (CustomerID, CustomerName, CustomerEmail) values (" + textbox1.value + ", " + textbox2.value + " + ", textbox3.value");SqlCommand cmd = new SqlCommand(insertstring, conn);Sql.ExecuteNonQuery();conn.close();}
If there is absolutely any insite into the problems with my code, I really appreciate it.
Creating SQL Statement That Returns Rows ONLY Between A Certain Date?
Sep 8, 2004I maintain a simple employment (job) tracking web application.
Jobs can be set to 5 different statuses: Open, Closed, Filled, Pending, or Cancelled.
There is a table in the database called statusLog, which records everytime a job is set to opened, or set to closed, etc. It records the job number, the date it was changed, and what the job was changed to.
Here is a short example of what a few entries might look like:
Status Date Job number
Open10/6/2002 2:34:56 PMTEST2845
Hold10/11/2002 12:19:29 PMTEST2845
Closed10/29/2002 2:00:54 PMTEST2845
Pending10/25/2002 3:37:06 PMTEST2877
What I need to do is write an SQL query that will return to me all entries in this table, between two certain dates, that ONLY have entries during those dates.
Basically I need to know how many "new" jobs were set to open during a month. I can easily just do a count of how many jobs were set to open, but this will not give a count of "new" jobs.
Example: during june a job could be set to open. Then in july it could be set to pending. Then in august, it could be re-opened, and set to open.
If I ran this query for the month of August, it would return that job as being opened in august. But it wasn't a new job, meaning it had already been in the system in previous months.
Is there some way I can select all "Open" jobs, between a certain date, that do not exist anywhere in the table previous to the date it was entered? This would give me a result set containing only new jobs.
The only way I've thought of yet is to get a result set of all jobs simply set to open during a month, then one by one for each record, go back and run another SQL query to see if it exists in the table anywhere other than in that month.
This seems horribly inefficient to me however, as I do not want to be doing 34,000 independent SQL calls for every single "open" job it finds during a certain month.
thanks
SQL 2012 :: Creating A Unique ID For Groups Of Rows?
Mar 20, 2015We have a sorted data that looks like the first 3 columns below, and fourth colum is what I want to create)
Shift_start meal_break shift_endShift ID
1 0 0 1
0 0 0 1
0 0 1 1
1 0 0 2
0 0 0 2

I need to find a method to assign unique Shift IDS to rows that correspond to a single shift. For instance, the first shift would begin on the first row when shift_start flag is turned on, and end on the third row when shift_end flag is turned on.
Can I do this in SQL ?...some kind of grouping ?

Creating Index Time Increases Poroportional To The Amount Of Rows???
Apr 28, 2008Hello!
I have a problem. I want to know if the time which is needed for creating an index increases proportional to the amount of rows. example: if creating an index on a table which 10.000 rows takes 15 seconds. does creating an index on a table with 20.000 rows take 30 seconds , 40.000 rows 60 seconds and so on...
or does it take longer like 10.000 rows 15 second, 20.000 rows 40 seconds, 40.000 rows 80 seconds.
thx for your help!!

Power Pivot :: Revenue Schedules - Creating Rows By Number Of Months
May 26, 2015I am trying to calculate how much revenue we may get, based on potential new business opportunities. The core fields we have are
Total Contract Value ($ or £)Duration of contract (months)Revenue start dateVarious information about the new business - ID, Title, Customer etc.
We can easily calculate the revenue per month with "Total Contract value divide by duration".
However what I would really like to do is be able to know how much revenue we will be getting each month.
To do this I was thinking we should probably create a new row for each month entry, with the mm-yyyy being the only difference for each row. But how to create the appropriate months and the correct amount of rows.

I would like to know how to create a single level hierachy structure in SQL.
Example, I have a single parent record in table A that may later on spawn one or child record in table B that relates back to the parent. It only needs a single level.
that means, one to many.

Tree
Jan 2, 2008I have two tables.
table1 has 3 fields a , b and c. field "a" is a primary key.
table2 has 2 fields x and y. Fields x and y are nothing but the value of "a". Also, y is the child of x.
Therefore, x and y can never have same value. It means value of "a" either be child or parent.
But there is possibility that parent has no child.
Now, i wanted to write Select/Insert query for parent, b , c and child.
This tree is no a binary tree but N-Ary Tree.
Thanks,

Tree-walking In T-SQL
May 18, 2007Hi,
I'm having a major brain-failure moment here.
Using T-SQL I want to be able to get all of the leaf nodes (e.g. nodes at the furthest end of a tree from the root) in a hierarchical relationship where the table structure is such NodeID|ParentID|NodeName.
Basically if I had the following tree structure:
Root
Child1
Grandchild1
Child2
Grandchild2
I want to get all of the Grandchild nodes. Number of levels will vary and I haven't got any kind of HasChilds column.
I know this is possible because I remember having done it on a course years ago but I can't for the life of me figure it out on this sunny Friday afternoon. I know it's going to involve either recursion, a while loop or cursors but my mind is currently jelly. Can anyone help?

Tree Structures In SQL
Jun 11, 2006Hi,
i'm writing a app in c# and have to store Trees in a Database.
I'm working with Datasets for the exchange between the DB and the App.
The trees have the same options like the windows folders. If u delete a node, all subnodes should be deleted too.
But something a Foreign Key from ParentID references (Id) with the delete-Rule on cascade seems not to be possible, because of multiple cascade Paths or cycles. Do i have to add some xtra constarins:
Not Possible:
create Table tree (
Id varchar Not null,
ParentId varchar Not null,
Constraint pk1 Primary Key (Id),
Constraint fk1 Foreign Key (ParentId) references tree(Id)
On Update Cascade
On delete CAscade
)
Do i have to write triggers, which delete The subnodes too and set the Update-/deleterulr on NO Action

Family Tree Branches
Jul 26, 2004Okie, this one has me a little stumped so bear with me an I will explain as best I can....
I have a family tree database...
The two key tables (for this problem) are Person and Child. The person table is your generic person details table and contains, PersonId, PersonFirstName, PersonLastName, PersonDOB etc. The Child table is a linking table that links a PersonId to a ChildPersonId (so both Id's are valid Id's in the person table).
Now what I want to try and achieve is a breakdown of the different branchs of the family tree. A branch is an independant, unattached section of the tree (if that makes sense). It's a grouping of people we know are related but we can't determine how they are related to another group of people in the tree.
If you look at this http://gw.geneanet.org/index.php3?b=bengos&lang=en;m=N;v=van+halewyn you will get an idea of what I mean.
I'm not sure if this is something that can be don't with a query at all the be honest... I suspect that I will have to wrap some other code around it, but I'm really not sure on what approach I should be using. Any help people could offer would be great.
