Choosing Between Two Column Values To Return As Single Column Value
Sep 14, 2007
I'm working on a social network where I store my friend GUIDs in a table with the following structure:
user1_guid user2_guid
I am trying to write a query to return a single list of all a users' friends in a single column. Depending on who initiates the friendship, a users' guid value can be in either of the two columns. Here is the crazy sql I have come up with to give what I want, but I'm sure there's a better way... Any ideas?SELECT DISTINCT UserId
FROM espace_ProfileProperty
WHERE (UserId IN
(SELECT CAST(REPLACE(CAST(user1_guid AS VarChar(36)) + CAST(user2_guid AS VarChar(36)), @userGuid, '') AS uniqueidentifier) AS UserId
FROM espace_UserConnection
WHERE (user1_guid = @userGuid) OR
(user2_guid = @userGuid))) AND (UserId IN
(SELECT UserId
FROM espace_ProfileProperty))
numbers 2 4 2Above is an example of my table with a single column. My problem is how to add all the numbers in that column to make it 8? The rows are also dynamic. Your help is highly appreciated.
I have a table that has multiple postal codes in one of the columns. Those have to be split up one per line and stored in another table. The zip codes are comma seperated. Is there a function that can do this...?
Example data in ZipCodeTable. (Name and ZipCode are 2 columns in a table)
I'm working on a query that is asking to return data on dependents which a person can have 0-many, in a single row but sep columns. The dependent data I need to include are Dep First Name, Dep Last Name, Dep Relationship.
Hi, I have a difficult case that I need to solve. I will try to be the very clear explaining my problem:
I have a sql query which brings me many records. This records have a column in common which have the same value (COL1)
There is a second column (COL2) which has different values bewteen these records. I need to concatenate values from the second column in records with same value in COL1. And I need only one record of the ones that have the same values. If two records have the same COL1 value, only one row should be in my result.
Let me give you an example: COL1 COL2 RECORD1 1-A HHH RECORD2 1-A GGG RECORD3 1-B LLL RECORD4 1-B MMM RECORD4 1-B OOO RECORD5 1-C NNN
Me result should be:
COL1 COL2 RECORD 1-A HHHGGG RECORD 1-B LLLMMMOOO RECORD 1-C NNN
It is clear what I need? I dont know if I can solve it through sql or any function inside SSIS. Thanks for any help you can give me.
I joined these two tables and it pulled up the proper amount of records. If you check out the image you will see what the results are for this query.
Now all I need for this part would be to roll these up where I have one row per ProgramID and all the AttributeNames' together in a AttributeNames column for each id.
EXAMPLE: All in one row.
ProgramID | AttributeNames 887 | Studydesign, Control Groups, Primary Outcomes.
I have attached an image of the SQL VIEW that I need to modified so it does this.
THE QUERY:
SELECT TOP (100) PERCENT dbo.tblProgramAttributes.ProgramID, dbo.tblProgramAttributes.AttributeID AS PAattributeID, dbo.tblAttributes.AttributeID, dbo.tblAttributes.AttributeName FROM dbo.tblProgramAttributes INNER JOIN dbo.tblAttributes ON dbo.tblProgramAttributes.AttributeID = dbo.tblAttributes.AttributeID WHERE (dbo.tblProgramAttributes.AttributeID NOT LIKE '%ProgramType%') ORDER BY dbo.tblProgramAttributes.ProgramID DESC
I have a stored procedure that returns a single row based on a parameter of employee ID. This particular procedure uses a CTE to traverse our org structure. One of the columns is returning a delimited string of Windows login values and due to the business rules, it can contain duplicate values. I need to have that column contain only unique values - no dupes.
For example, this one column could contain something like this:
I need to write a select query that gets the values of all columns but only returns unique sites because some sites are load balanced across several servers and where this is the case I don't want the site to appear multiple times in the list.
Suppose that I have a table with following values Table1 Col1 Col2 Col3 ----------------------------------------------------------- P3456 C935876 T675 P5555 C678909 T8888
And the outcome that I want is: CombinedValues(ColumnName) ---------------------------------------------- P3456 - C935876 - T675 P5555 - C678909 - T8888
where CombinedValues column contains values of coulmn 1,2 & 3 seperated by '-' So is there any way to achieve this?
I think it was Pat Phelan who posted a little trick here where he used the STUFF function to create a string fo values from a column without using a cursor.
I am starting a brand new project and I did my table design and I am awaiting a finalized requirements document to start coding and I thought I would spend a little time writing some code to autogenerate some generic one record at a time SELECT, INSERT,UPDATE and DELETE stored procedures. With the coming holiday things are getting quiet around here.
The code that is not working is listed below. It does not work. It returns Null. I suck.
DECLARE @column_names varchar(8000)
SET @column_names = ''
SELECT @column_names = STUFF(@column_names,LEN(@column_names),0,C.COLUMN_ NAME + ', ') FROM INFORMATION_SCHEMA.COLUMNS C WHERE TABLE_NAME = 'MyTable'
12.) Now you have two different tables - each with two columns.Table #1Single Column2 rows with a value equal to 1 and 2Table #2Single column2 rows with a value equal to 2 and 4Construct a statement returning in a single column all the valuescontained, but not the common values.This is another question that I got in an interview, I missedit.......Thanks,Tim
I am trying to count a column field in a single table and return two count values as one record set using group by.
field1 = group by (department) nvarachar field2 = count (closed) datetime
I have tried using derived tables with no luck getting the desired result.
field2 is a datetime field as indicated I want a count for two conditions
1. WHERE field2 is null 2. WHERE field2 is not null
End Results would like this ====== Department | OpenItems | ClosedItems Department1 | 32 | 24 Departmnet2 | 87 | 46 Department3 | 42 | 76
=======
I got it *almost* working with derived tables, but the group by function was not putting the department as one single row. I was getting multiple rows for departments.
I realize this is probably a simple answer and I am making this a lot harder than it actually is....
Hi, I have a table called geofence. It has a primary key geofence_id. Each geofence consists of a set of latitudes and latitudes. So I defined two columns latitude and longitude and their type is varchar. I want to store all latitude/longitude values as a comma separated values in latitude/longitude columns So in general how do people implement these types of requirements in relational databases?
i have a report with contains preview of percentage columns example of percentage of student marks in perticular subject like 95%. and if suppose any student not attend any test i have to dispaly like not attended statement.
so i have display two fields like 95% and not attended statement in same column, i given Cstr(Fields!Data.Value), it gives two fields with contains not attended statement of perticular query and it dispalys 0.95 % . but i need 95% and not attended statement for perticular query in same column.
is there any solution for dispalying string and percentage values in single column for given perticular query and those two values are disply same result compare with preview at the time of export to excel sheet
I need to check whether procedure found any matches or not. If not it has to return the column name where matching value was not found. For example, if there was no record found in the table "Addresses" column "customer" with the value @username, it should return "street". If id with value @prod_id was not found in the table "Products", the "productname" must be returned as well.
CREATE PROC sp_test @id INT, @username VARCHAR(50), @prod_id INT AS
SELECT name FROM Customers WHERE id=@id SELECT street FROM Addresses WHERE customer=@username SELECT productname FROM Products WHERE id=@prod_id
It is kind of check, which has to find out if users have inserted all the necessary values or not. Thanks for any advice.
We have SharePoint list which has, say, two columns. Column A and Column B.
Column A can have three values - red, blue & green.
Column B can have four values - pen, marker, pencil & highlighter.
A typical view of list can be:
Column A - Column B red - pen red - pencil red - highlighter blue - marker blue - pencil green - pen green - highlighter red - pen blue - pencil blue - highlighter blue - pencil
We are looking to create a report from SharePoint List using SSRS which has following view:
red blue green pen 2 0 1 marker 0 1 0 pencil 1 3 0 highlighter 1 1 1
We tried Sum but not able to display in single row.
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.
I have both positive and negative values in a single column, where I want sum total of positive values & negative values. Is there any Expression for this to sort out.
How do I pass a single column of values from a successful merge join to an EXECUTE SQL statement so it can be used with an "IN" criteria of the WHERE clause? Here's an example of my update statement with two random key values:
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK IN ("XYZ123", "DEF890")
Is this even possible in SSIS, or am I better off using a loop and running the update EXECUTE SQL Statement for each individual key value, as in the following example?
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "XYZ123" UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "DEF890"
I have two tables, one a data table, the other a product table. I want to perform a join on the two tables with values distributed into columns based on the value in the month field.
Hi,Would like to know the performance differenece between Multi-columnIndex vs Single Column Indexes. Let's say I have a table with col1,col2, col3 along with a primary key column and non-indexed columns.In queries, I will use col1, col2, and col3 together and some timesjust one or two of these three columns. My questions is, should Icreate one index contains col1, col2, and col3, or create 3 seperatedcolumns. I.e. each column has its own index. Any performancedifference?Thanks a lot.
I have created a single FULLTEXT on col2 & col3. suppose i want to search col2='engine' and col3='toyota' i write query as
SELECT
TBL.col2,TBL.col3 FROM
TBL INNER JOIN
CONTAINSTABLE(TBL,col2,'engine') TBL1 ON
TBL.col1=TBL1.[key] INNER JOIN
CONTAINSTABLE(TBL,col3,'toyota') TBL2 ON
TBL.col1=TBL2.[key]
Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.
I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information. for e.g.; i was thinking to concatinate both fields like col4= ABengineBA + ABBToyotaBBA and in search i use SELECT
TBL.col4 FROM
TBL INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1 ON
TBL.col1=TBL1.[key] Result = 1 row
But it don't work in following scenario col4= ABengineBA + ABBCorola ToyotaBBA
SELECT
TBL.col4 FROM
TBL INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1 ON
TBL.col1=TBL1.[key]
Result=0 Row Any idea how i can write second query to get result?
This is a report I'm trying to build in SQL Reporting Services. I can do it in a hacky way adding two data sets and showing two tables, but I'm sure there is a better way.
TheTable Order# Customer Status
STATUS has valid values of PROCESSED and INPROGRESS
The query I'm trying to build is Count of Processed and INProgress orders for a given Customer.
I can get them one at a time with something like this in two different datasets and showing two tables, but how do I achieve the same in one query?
Select Customer, Count (*) As Status1 FROM TheTable Where (Status = N'Shipped') Group By Customer
