SELECT
COL_1

SQL Server 2012 :: Create Dynamic Update Statement Based On Return Values In Select Statement

Jan 9, 2015

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".

Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

Is There A Way To Create Columns From A Row Value In A Select Statement?

Jan 30, 2008



Hi!

I have a select question that look like this:


DECLARE @ID uniqueidentifier;

SET @ID = '40bd3052-60f4-414a-99df-ca882c128493';


SELECT

rp.ID AS ReportPackId

,rp.SupplierPartyIdentifier AS SupplierPartyIdentifier

,rpap.AdditionalPartyIdentifier AS AdditionalPartyIdentifier

FROM

ReportPack rp

INNER JOIN ReportPackAdditionalParty rpap

ON rpap.fk_ReportPack = rp.ID

WHERE rp.ID = @ID

The result a get when running the select question is:








ReportPackId
SupplierPartyIdentifier
AdditionalPartyIdentifier

40BD3052-60F4-414A-99DF-CA882C128493
String
addPartyId1

40BD3052-60F4-414A-99DF-CA882C128493
String
addPartyId2

My problem is that the result I want is the following:









ReportPackId
SupplierPartyIdentifier
AdditionalPartyIdentifier
AdditionalPartyIdentifier

40BD3052-60F4-414A-99DF-CA882C128493
String
addPartyId1
addPartyId2

I always know that the ReportPackId and SupplierPartyIdentifier will be identical for all rows because of the Where condition, and therefore I want all AdditionalPartyIdentifiers to be in columns instead of a new row. Is this possible?

Dynamic CREATE TABLE Or SELECT INTO Statement

Jul 27, 2004

In SQL Server you can do a SELECT INTO to create a new table, much like CREAT TABLE AS in Oracle. I'm putting together a dynamic script that will create a table with the number of columns being the dynamic part of my script. Got any suggestions that come to mind?

Example:

I need to count the number of weeks between two dates, my columns in the table need to be at least one for every week returned in my query.

I'm thinking of getting a count of the number of weeks then building my column string comma separated then do my CREATE TABLE statement rather then the SELECT INTO... But I'm not sure I'll be able to do that using a variable that holds the string of column names. I'm guess the only way I can do this is via either VBScript or VB rather then from within the database.

BTW - this would be a stored procedure...

Any suggestions would be greatly appreciated.

Unable To Create Variable Select Statement In For Each Loop

Apr 24, 2007

What I'm trying to do is this;

I have a table with Year , Account and Amount as fields. I want to



SELECT Year, Account, sum(Amount) AS Amt

FROM GLTable

WHERE Year <= varYear



varYear being a variable which is each year from a query



SELECT Distinct Year FROM GLTable



My thought was that I would need to pass a variable into a select statement which then would be used as the source in my Data Flow Task.



What I have done is to defined two variables as follows

Name: varYear (this will hold the year)

Scope: Package

Data type: String



Name:vSQL (This will hold a SQL statement using the varYear)

Scope: Package

Data type: String

Value: "SELECT Year, Account, sum(Amount) AS Amount FROM GLTable WHERE Year <=" + @[User::varYear]



I've created a SQL Task as follows

Result set: Full Result Set

Connection Type: OLE DB

SQL Statement: SELECT DISTINCT Year FROM GLTable

Result Name: 0

Variable Name: User::varYear



Next I created a For Each Loop container with the following parameters

Enumerator: Foreach ADO Enumerator

ADO Object source Variable: User::varYear

Enumeration Mode: Rows in First Table



I then created a Data Flow Task in the Foreach Loop Container and as the source used OLE DB Source as follows

Data Access Mode: SQL Command from Variable

Variable Name: User::varYear



However this returns a couple of errors "Statement(s) could not be prepared."

and "Incorrect syntax near '='.".



I'm not sure what is wrong or if this is the right way to accomplish what I am trying to do. I got this from another thread "Passing Variables" started 15 Nov 2005.



Any help would be most appreciated.

Regards,

Bill

How Do I Get The Actual Name Of A Column Or Table In A Sql Select Statement?

Jul 12, 2004

Hello fellow .net developers,

In a website I'm working on I need to be able to put all of the user tables in a database in a dropdownlist.

Another dropdownlist then will autopopulate itself with the names of all the columns from the table selected in the first dropdownlist.

So, what I need to know is: is there a sql statement that can return this type of information?

Example:

Table Names in Database: Customers, Suppliers

Columns in Customers Table: Name, Phone, Email, Address

I click on the word "Customers" in the first dropdownlist.

I then see the words "Name", "Phone", "Email", "Address" in the second dropdownlist.

I'm sure you all know this (but I'll say it anyways): I could hardcode this stuff in my code behind file, but that would be really annoying and if the table structure changes I would have to revise my code on the webpage. So any ideas on how to do this the right way would be really cool.

Thanks in advance,

Robert

Dynamic Column Names In Select Statement

Oct 13, 2001

I have a quick question on SQL Server. Lets say I have table Order which has column names OrderId, CustomerName, OrderDate and NumberofItems. To select the OrderID values from the table I say
Select OrderId from Order.
But in the select if I want the column name to be variable how do I do it. I tried the following code through a stored procedure.

declare @order_id nvarchar(10)
select @order_id = 'OrderID'
SELECT @order_id from Order.

The code above gave me the string "OrderID" as many times as there were rows in the table but I could never get the actuall values in the OrderId column. Can you please send me some ideas or code where I can get values from the column names and at the same time change the column name dynamically.

Hiding Or Removing Column Output From Select Statement

Feb 22, 2005

I'm executing the following...

select COL1, min(COL2) from TABLE group by COL1

the table has many duplicate entries, where COL2 is the primary key and unique, but its the duplicate COL1 entries that have to be removed.

I was hoping a simple
"delete from table where COL1 not in (select COL1, min(COL2) from TABLE group by COL1)"

would do the trick, but obviously in returning two columns from the subselect this won't work. Can I hide the COL2 output from the query that will be put in the subselect?

this is a one-off thing, so i'm not overly concerned about overhead or elegance. just need to make it so.

T-SQL (SS2K8) :: Pass A Column Name Using Parameter In Select Statement

Sep 5, 2014

I have a temp table that hosts data from a MDX query, I want to select a column from that table by passing in a parameter and then insert to a new table.

Here's the table structure, let's call it #temp

[Product].[Product Hierarchy].[level 03].[Member_CAPTION], [Measures].[Gross Sales]
Bike, 200
Accessory , 100

I have a table in the DB created as [ProductSales]

Here's what works for me:

insert into [ProductSales](Product, Sales)
Select convert(varchar(20), "[Product].[Product Hierarchy].[level 03].[Member_CAPTION]") as 'Product' , convert(decimal(18,2), [Measures].[Data]) as 'Sales'
From #temp

But in reality the product level is not always on level 03, I want to define a parameter @Product and pass it to the select list.

Here's what I tried to do:

Declare @Product varchar(500) = convert(varchar(20), "[Product].[Product Hierarchy].[level 01].[Member_CAPTION]")
Declare @SQL varchar(MAX)
SET @SQL='insert into [ProductSales](Product, Sales)
Select '+@Product+' as 'Product' , convert(decimal(18,2), [Measures].[Data]) as 'Sales'
From #temp'
Exec @SQL

But it threw me error, what is the right way to do it, is it because the double quote or single quote thing?

Select Into Statement Without Taking Auto Increment Of ID Column To The New Table

Mar 7, 2011

Due to localization I have the need to make child tables, where there is a composite Primary Key, between the Id column and the LanguageSign column. On the parent table the Id column is Identity column with auto increment.

The problem is that during the select into query to copy columns from parent to child, this auto increment behaviour of the parent-Id is copied to the child-Id. However I do not want that, because the same Id will be used by different LanguageSign entries

Is there a way to use 'select into' without copying the auto increment, or is my only option to make a whole new column without auto increment on the child and copy the records?
 
btw I have used this statement

SET
IDENTITY_INSERT MyTable

ON , so that inserting into the Id column is possible. I can see however that this does not take away the auto increment...

Can A Column Be Derived Using Substring But The Parameters Are A Result Of A Select Statement?

Apr 6, 2007

I have a table which has a field called Org. This field can be segmented from one to five segments based on a user defined delimiter and user defined segment length. Another table contains one row of data with the user defined delimiter and the start and length of each segment. e.g.









Table 1

Org

aaa:aaa:aa

aaa:aaa:ab

aaa:aab:aa








Table 2














delim

Seg1Start

Seg1Len

Seg2Start

Seg2Len

Seg3Start

Seg3Len


:

1

3

5

3

9

2



My objective is to use SSIS and derive three columns from the one column in Table 1 based on the positions defined in Table 2. Table 2 is a single row table. I thought perhaps I could use the substring function and nest the select statement in place of the parameters in the derived column data flow. I don't seem to be able to get this to work.



Any ideas? Can this be done in SSIS?



I'd really appreciate any insight that anyone might have.



Regards,

Select Statement That Will Output Related Rows With Different Column Data Per Row?

Apr 27, 2008

Is there a way to build a select statement that will output related rows with different column data per row? I want to return something like:


rowtype| ID | value
A | 123 | alpha
B | 123 | beta
C | 123 | delta
A | 124 | some val
B | 124 | some val 2
C | 124 | some val 3
etc...

where for each ID, I have 3 rows that are associated with it and with different corresponding values.

I'm thinking that I will have to build a temp table/cursor that will get all the ID data and then loop through it to insert each rowtype data into another temp table.

i.e. each ID iteration will do something like:
insert into #someTempTable (rowtype, ID, value) values ('A', 123, 'alpha')
insert into #someTempTable (rowtype, ID, value) values ('B', 123, 'beta')
insert into #someTempTable (rowtype, ID, value) values ('C', 123, 'delta')
etc..

After my loop, I will just do a select * from #someTempTable

Is there a better, more elegant way instead of using two temp tables? I am using MSSQL 2005
