Update Table With Data Calculated From The Same Table
Sep 21, 2007
Hello,
I'm attempting to explore the functionality of SSIS and all the available data flow transformations, and I'm trying to learn how to use the tool correctly.
How would someone update a table with data which is calculated from that same table.
This is a made up example. Lets say I have a table:
I would like to populate the field color_count with the count of items listed with that color.
Data:
tst_key object color color_count
1, chair blue NULL
2, table black NULL
3 lamp black NULL
----
So the last column for 1st rec value would be 1, and for 2nd and 3rd, would be two.
tst_key object color color_count
1, chair blue 1
2, table black 2
3 lamp black 2
-- With T-SQL I would use the following code:
update tst_source
set color_count = res.cnt
from tst_source
Inner join (select count(tst_key) cnt,color
from tst_source
group by color) res
ON res.color = tst_source.color
But I would like to use the Data Transformations. Can someone explain in great detail which Data Transformation tasks I would need to use?
I have 2 tables: Order(ID, Quantity) and Product(ID,Name, Price) and I want to add a calculated field in Order table based on the price column in the Product table. How do i do that?
this query returns the values i want in the table.
select a.quantity * b.price from tblCustomerPurchases as a join tblProduct as b on a.ID=b.ID
I have a table called ADSCHL which contains the school_code as Primary key and other two table as
RGDEGR(common field as SCHOOl_code) and RGENRl( Original_school_code) which are refrencing the ADSCHL. if a school_code will be updated both the table RGDEGR (school_code) and RGERNL ( original_schoolcode) has to be updated as well. I have been provided a new data that i have imported to SQL server using SSIS with table name as TESTCEP which has a column name school_code. I have been assigned a task to update the old school_code vale ( ADSCHL) with new school_code ( TESTCEP) and make sure the changes happen across all 3 tables.
I tried using Merge Update function not sure if this is going to work.
Update dbo.ADSCHL SET dbo.ADSCHL.SCHOOL_CODE = FD.SCHOOL_Code FROM dbo.ADSCHL AD INNER JOIN TESTCEP FD ON AD.SCHOOL_NAME = FD.School_Name
I have two tables ingram and ingram_update that have the identical fields. I need to update ingram with the content in ingram_update. How do I do this? Thank you for your help!
Table1: FullName, City, State, Data1 Table 2: FullName, City, State, Data1, Data2, Data3
This is what I want to do... 1. For every record that is in BOTH tables I want to UPDATE TABLE 2 with the data from Table 1. 2. Then, if there are "extra"/new records in table 1 I want to append them to Table 2.
How would I do this? Can you provide syntax? I'm new.

Hi,First post so apologies if this sounds a bit confusing!!I'm trying to run the following update. On a weekly basis i want toinsert all the active users ids from a users table into a timesheetstable along with the last day of the week and a submitted flag set to0. I plan then on creating a schduled job so the script runs weekly.The 3 queries i plan to use are below.Insert statement:INSERT INTO TBL_TIMESHEETS (TBL_TIMESHEETS.USER_ID,TBL_TIMESHEETS.WEEK_ENDING, TBL_TIMESHEETS.IS_SUBMITTED)VALUES ('user ids', 'week end date', '0')Get User Ids:SELECT TBL_USERS.USER_ID from TBL_USERS where TBL_USERS.IS_ACTIVE = '1'Get last date of the weekSELECT DATEADD(wk, DATEDIFF(wk,0,getdate()), 6)I'm having trouble combing them as i'm pretty new to this. Is the bestapproach to use a cursor?If you need anymore info let me know. Thanks in advance.
I'm trying to update a single record in a table using data from a single record in another table. For the life of me I can't figure this out. I'm trying to avoid having to write a bunch of +=" string stuff in C#. Is there any way to do this with just SQL?Thanks in advance.
I want to add to a column in one table the data in another. I have tried different update statements and none work. My update statement currently looks like this:
update t1 set t1.amtYTD = t1.amtYTD + t2.Total from #ProgramData t1 join vw_MER_Reclass t2 on (t1.ProjId = t2.ProjId and t1.task = t2.task and t1.acct = t2.acct)
I need to take the amtYTD in table1, and add to it the value of Total in table 2.
I want to update table2.message based on the criteria of table1.name. for example, all records named John will be updated with 'Msg1' in table 2.message. I am using MS SQL 2000 and below is the scenario.
table1 columns ID Name
table2 columns ID Message
Select a.Id, a.name, b.message from table1 a, table2 b where a.id =b.id
a.id a.name b.message 1 John Msg1 2 Steve Msg2 3 Scott Msg3 4 John NULL - update b.message to 'Msg1' 5 Steve NULL - update b.message to 'Msg2' 6 Scott NULL - update b.message to 'Msg3' 7 John NULL - update b.message to 'Msg1' 8 Steve NULL - update b.message to 'Msg2'
If i will update the record per name i am using the query below and i am pre-selecting all the existing names.
update table2 b set b.message=(Select top 1 b.message from table1 a, table2 b where a.id =b.id
[Code] ...
How to update this in bulk without preselecting all the names?
OK, I'm trying to add some audit type information to a set of tables in my database. This involves adding 2 columns and sticking some data into those two columns. The columns themselves are added successfully, but I'm having troubles sticking any data into them - I'm getting a lot of errors. What I want to do is put a single character code in one column, and a datetime in the second. Here's the SQL I'm trying...
Conversion failed when converting datetime from character string.
I tried changing the datetime column to varchar, and CONVERT(varchar(30),@TxDateTime). That gets rid of the above error, but replaces it with the following (twice, I might add - one for each column?):
Msg 213, Level 16, State 1, Line 1
Insert Error: Column name or number of supplied values does not match table definition.
Any help is appreciated - let me know if you need more info.
Hi, This is probably straightforward but I'm not sure how to approach this problem.
I have 2 tables, one parent and a child. The child table has a Quantity and a Price field and also a FK to the parent table.
I want the parent table to display its own row data along with the Total Cost of the child rows in the child table. So it needs to multiply the price by the quantity but also do a sum of this calculated column.
To start off with I tried SUM( TOTALCOST ) and it didn't like it. I've got an idea I might need to create a View but was wondering what is the standard way of doing something like this? E.g.
I need to update the Denominator column in one row with the value from the Numerator column in a different row. For example the last row in the table is
c010A92NULL
I need to update the Denominator, which is currently NULL, with the value from the Numerator where the MeasureID=c001 and GroupID=A.

Hello all,my first post here...hope it goes well. I'm currently working onstored procedure where I translated some reporting language into T-SQLThe logic:I have a group of tables containing important values for calculation.I run various sum calculations on various fields in order to retrievecost calculations ...etc.1) There is a select statement which gathers all the "records" whichneed calculations.ex: select distinct Office from Offices where OfficeDesignation ='WE' or OfficeDesignation = 'BE...etc.As a result I get a list of lets say 5 offices which need to becalculated!2) A calculation select statement is then run on a loop for each ofthe returned 5 offices (@OfficeName cursor used here!) found above.Anexample can be like this(* note that @WriteOff is a variable storing the result):"select @WriteOff = sum(linecost * (-1))From Invtrans , InventoryWhere ( transtype in ('blah', 'blah' , 'blah' ) )and ( storeloc = @OfficeName )and ( Invtrans.linecost <= 0 )and ( Inventory.location = Invtrans.storeloc )and ( Inventory.itemnum = Invtrans.itemnum )"...etcThis sample statement returns a value and is passed to the variable@WriteOff (for each of the 5 offices mentioned in step 1). This is donearound 9 times for each loop! (9 calculations)3) At the end of each loop (or each office), we do an insert statementto a table in the database.
Hello I am new to SSIS and learning as I go. Any guidance to my questions would be appreciated.
I wrote a script that takes the current date and subtracts a number of days/months from this date. I then attempted to use an SQL Task as a select with a parameter using the calculated date from the script. I was not successful in doing this. While performing searches on the WEB with the hopes of finding a solution I came upon the following text in the Microsoft forum under EXECUTE SQL TASK.
When you use an OLE DB Connection Manager, you cannot use parameterized subqueries because the Execute SQL task cannot derive parameter information through the OLE DB provider. However, you can use an expression to concatenate the parameter values into the query string and to set the SqlStatementSource property of the task.
Having come upon this statement I moved on to putting together an OLE DB SOURCE with a Flat File Destination. The SQL that I wrote is:
SELECT BP_ID, INVC_NBR, INVC_DT, BUS_ADD_DT FROM DW.CUST_SALE_ADDR WHERE (BUS_ADD_DT = ?)
The flat file destination was mainly used to confirm the select.
Having confirmed my select, I changed the select in the OLE DB SOURCE as follows:
DELETE FROM DW.CUST_SALE_ADDR WHERE (BUS_ADD_DT = ?)
I also removed the Flat File Destination. Needless to say when I tried to run the package I did not get very far as a package validation error was encountered since there were no output columns.
Can you share how I should go about peforming the delete as described from the table based on a calculated date? And am I not understanding the comment regarding the SQL Statement and the use of parameters?
I have a table that contains a column for a calcuated member (x) of type decimal number. When I tried to display the total of this calculated member in the table footer (=sum(x)), I am getting "#Error" instead of the sum of all displayed calculated values.
Column X
--------------
0
0.67
0.10
0.23
#Error (footer cell, expression -> =Sum(x))
=First(x), =Last(x) and =Max(x) worked fine, not sure why Sum failed. Please help...
Is it possible to allow a user to insert and update data in a table but prevent them from performing deletes against that same table? For auditing purposes I need to prevent the end users from being able to delete data.

Problem: I have a calculated field on a PO table that adds up item prices on an Item table to get the total PO value. This works as expected until there are at least 10 rows in the PO table. From the 10 row on the calculated field stops working and only shows 0.
I have experienced this before and it seems like calculated fields break on the 10th row of a table and onward.
My PO table CREATE TABLE [dbo].[PO]( [ID] [int] IDENTITY(1,1) NOT NULL, [Quote_Number] [varchar](max) NULL, [Customer] [varchar](max) NULL, [CustomerPO] [varchar](max) NULL, [PO_Received_Date] [datetime] NULL, [Total_PO_Value] [decimal](18, 2) NULL,
I have a table dbo.Sales that contains all sales records. There is a column in that table called ItemNumber that I'd like to match with ItemNumber in a flat file and update the ItemCost based on the ItemCost column in the flat file.
So while there will be many sales records for each ItemNumber, I need to loop through and update the ItemCost in that sales record based on the corresponding ItemCost in the flat file. Does this make sense? I really need this for court and I can't figure out how to do it. I took a SQL course about 7 years ago but have forgotten everything.
There will be many sales records for each ItemNumber in the database table. I need to update each one with correct cost based on the item number and cost mapping from flat file.
Every month a client sends a spreadsheet with data which we use to update matching rows in a table in the database. I want to automate this using a DTS package but am having quite a bit of trouble accomplishing what I think should be trivial task. I've been attempting to use a Transform Data Task with a modification lookup but I just keep inserting the rows from the source excel spreadsheet in to the existing destination table without ever modifying the existing data.
Any guidance would be greatly appreciated as to a best practice approach.
I imported a SQL Table into SQL DataBase, But I can not update this table even with SQL Server management Studio When I change any data on mentioned table above, Red exclamation sign appears left of the record . How can I correct this problem? Thanks.
