Derive A Column Based On Other Derived Column In A Table .. Is It Possible ?
Mar 25, 2008
Table structure as follows
Employee
Empno empname salary
commission
I want to have an other employee table named employee_modified
Empno empname salary
commission derived_column1(salary+commission)
derived_column2(derived_column1 + xxxx) and so on derive other
columns based on the earlier derived columns)
Is that possible to do it.. or am I doing something wrong.
I have a excel file which has a column called "Code" and their values are A,B,C,D,E,F,G,H. I want to create a new column called "status" based on the values of "Code".
Code:
A B C D E F G H
If A,C,E,G then "status" = "Active" else if B,D,F,H then "Status" = "Inactive". I like to do it using "Derived Column".
Is there any way to get the base table/column from a view by supplying the view name/column name_in_view? I know about INFORMATION_SCHEMA.VIEW_COLUMN_USAGE, but it doesn't always work. Try it on a regular database, not pubs. Any help is appreciated!
how to declare multiple derived columns in SSIS Derived Column Task in one attempt.as i have around 150 columns coming from Flat file. I had created the required Expression in Excel and now i want add those in derived column task but its allowing only 1 expression at a time.
I have a MS SQL table with a derived column, for date the records were imported, and need to delete records, based on the content of this column. What I need to do is delete all records from the table with a date of '2011-11-18'. Now this column is a datetime column, so it contains the time info after the date, i.e. 2011-11-18 09:29:38.000, but no matter what command I try for this:
-Delete from table where Date_Imported like '2011-11-18%' -Delete from table where Date_Imported like '2011-11-18' -Delete from table where Date_Imported = 2011-11-18
It comes back saying "0 rows affected", even though I know there are records with that date in the table.
I need to create a derived column for each row in a SQL dataset.
This derived column needs to be created by passing across two values from the SQL dataset and querying an Oracle table based on those parameters. If the Oracle query returns a record(s) then the derived column should be set to 1 otherwise leave it as default (0).
One of these parameters needs to check a date range so I can't use a Lookup Transformation...any ideas how I can accomplish this ?
I have 3 different companies that share the same ticket_types(CRMS System). I need to display the Ticket Types and the 3 company's Ticket Count:
Ticket Type | Company A Count | Company B Count | Company C Count
I can get the information individually for each company, but if a company doesn't have a ticket in one of the ticket_types, then it isn't displayed in a row. So, I tried to write the following, which isn't pulling back any data.
DECLARE @startdate date = '20150306' DECLARE @enddate date = '20151031' DECLARE @AcctGrp varchar(20) = '111' ;WITH TType AS ( SELECT ctp.description as TicketType
[Code] .....
If I run each SELECT individually from above (excluding the last SELECT), it works and I get the following:
TicketType AR Request Credit Availability/Rush Cancel Order Credit Card Payment Expedite Order Freight Quote
[Code] ...
How to get the query results? Am I even close to getting it right?
I've a bit field named "Active" and a varchar [Name] field I want to select a derived fields "DisplayName" that consists of the Name plus either "Active" or "Not Active" depending if Active is 1 or 0. Something like SELECT [Name]+(IF Active THEN ' Active' ELSE ' Not Active') AS DisplayName FROM Lookups ORDER BY DisplayNamebut that doesn't work. Any suggestions please?
Hi, I have dates in "mmddyy" format coming from the sources and they are older dates of mid 80s like 082580 for instance.
When I cast it this way (DT_DBTIMESTAMP) Source_Date , It says ok but throws a runtime error.
When I hardcode a date in same format, (DT_DBTIMESTAMP) "082580" , It becomes red (an indication of syntax error) . Please note that we use double quotes in expressions in Derived Column Transformation; So an anticipation that using double quotes over single ones would be the syntax problem would be wrong.
I have a derive column( sequence) transformation in data flow , i am trying to assign this column to a variable , so that i can use it in the SQLtask control flow... how can i do this? can you show me some examples?
Hey all - got a problem that seems like it would be simple (and probably is : )
I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me.
Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs:
' Copy each source column to the destination column Function Main() DTSDestination("CM") = Month(Now) DTSDestination("CY") = Year(Now) DTSDestination("Comments") = DTSSource("Col031") DTSDestination("Manufacturer") = DTSSource("Col030") DTSDestination("Model") = DTSSource("Col029") DTSDestination("Last Check-in Date") = DTSSource("Col028") Main = DTSTransformStat_OK End Function *********************************************************** Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data.
Hi, how are you? I'm having a problem and I don't know if it can be solved with a derived column expression. This is the problem:
We are looking data in a a sql database.
We are writting the SQL result in a flat file.
We need to transform data in one of the columns.
For example: we can have 3 digits as value in a column but that column must be 10 digit length. So we have to complete all the missing digits with a zero. So, that column will have the original 3 digits and 7 zeros. How we can do that tranformation? We must do it from de the flat file or it can be a previous step? Thanks for any help you can give me. Regards,
I am looking for the best way in SSIS to do the following. I have an SQL table that for each row in the table I want to take an element from the table do a lookup in a Teredata Table, return information from the teredata source. Use that returned data to do some calculations and create a derived column from my calculations and place the data into the same SQL table that I am parsing through.
In a Derived Column data flow transformation, why can't I refer to a derived column (added in that same transformation) in the expression for another derived column? It seems I am forced to chain 2 DC data flows, just to do something as conceptually simple as:
a = x + y; b = a²
On a related note: Can I define a variable that is scoped to each row? Can I bind a variable in an expression to avoid creating a new row, e.g.
I am designing a dimension table which will include a short name column based on the (full) name column. For example say Product dimension where I will have ProductName and ProductShortName. ProductShortName will be the first 6 characters of ProductName. I could populate ProductShortName using:
Substring in the select when I select from the original system, e.g. SUBSTR(PRODUCT_NAME, 1, 6) AS ProductShortName
Create a derived column in the SSIS flow which does the same thing
Create the ProductShortName column as a computed column which uses substring on ProductName
Create a trigger that populates ProductShortName based on ProductName when a row is inserted or updated
Create a named calculation in the table in the Analysis Services project's data source view
Create a named query in the Analysis Services project's data source view
I usually use 1, and 5 or 6 would only be used if I only will create reports against the cubes. 3 seems easiest to maintain, so I am thinking about using that one, but maybe it is slow for the data flow as I imagine it must be something like using 4, or when is the column "created" at runtime, i.e. when the table is queried? Which approach(es) do or would you use? Pros and cons?
Using MDS 2012: I have an entity "XYZ_Entity". In "XYZ_Entity" entity I have 2 domain based Columns "DealerGroup" and "Dealer".
While inserting information into "XYZ_Entity" entity user can select the required dealer group from domain base Dealer Group values. Now for selecting Dealer he wants the dealers to be filter based on selected dealer group and he can select from the filtered list. reason to do that is he don't want to go through thousands of dealers and select an incorrect one.
Hi,Suppose I have a table containing monthly sales figures from my shopbranches:Branch Month Sales-----------------------London Jan 5000London Feb 4500London Mar 5200Cardiff Jan 2900Cardiff Feb 4100Cardiff Mar 3500The question I am trying to ask is this: in which month did each branchachieve its highest sales? So I want a result set something like this:Branch Month----------------London MarCardiff FebI can do a "SELECT Branch, MAX(Sales) FROM MonthlySales GROUP BY Branch" totell me what the highest monthly sales figure was, but I just can't figureout how to write a query to tell me which month corresponded to MAX(Sales).Ideas anyone?Cheers,....Andy

I am using Reporting Services 2000. If you find out that Reporting Services 2005 would resolve this issue, please lemme know also. But I want to mention that I would prefer a way to fix this without changing Reporting Services versions.
I have a table that has a group on ProductTypes. This group is set to PageBreak at end. What I need to do is to conditionally hide an entire column based on the current group's ProductType.
Can you help me figure this one out ? I've tried everything I found on the net, especially everything on this page : http://blogs.msdn.com/chrishays/rss.xml
We are facing few issues pertaining to creation of primary key on a non - partitioned column in sql server 2005. Herewith attaching the text file containing the detailed scenario.
Pls advice.
Pls find some of the scenario with the example given below:
We have done the following steps 1.Creating a Partition Function CREATE PARTITION FUNCTION pf_EncounterODS_StateID (CHAR(2)) AS RANGE RIGHT FOR VALUES ( 'CA', -- CA 'MI', -- MI 'NM', -- NM 'OH', -- OH 'TX', -- TX 'UT', -- UT 'WA' -- WA ) GO 2.Creating a Partition Schema CREATE PARTITION SCHEME [ps_EncounterODS_StateID] AS PARTITION pf_EncounterODS_StateID TO ( [PRIMARY], [ENC_DM_DATA_01], -- CA [ENC_DM_DATA_03], -- MI [ENC_DM_DATA_04], -- NM [ENC_DM_DATA_05], -- OH [ENC_DM_DATA_06], -- TX [ENC_DM_DATA_07], -- UT [ENC_DM_DATA_02] -- WA ) GO
4.Creating a primary key on validationErrorSID column in the fact table ALTER TABLE [Fact] ADD CONSTRAINT NQValidationError PRIMARY KEY CLUSTERED ([ValidationErrorSID]) Step 4 throws an error as --------------------------------- Column 'StateID' is partitioning column of the index 'NQValidationError'. Partition columns for a unique index must be a subset of the index key. If we include StateID along with ValidationErrorSID for index,then it works fine.But we need to have only ([ValidationErrorSID]) for indexing.
i have the folowing databases DB1,DB2,DB3,D4,DB5........
i have to loop through each of the databases and find out if the database has a table with the name 'Documents'( like 'tbdocuments' or 'tbemplyeedocuments' and so on......)
If the tablename having the word 'Documents' is found in that database i have to add a column named 'IsValid varchar(100)' against that table in that database and there can be more than 1 'Documents' table in a database.
Table: classes Columns: classID, hp Table: char_active Columns: name, classID, hp
The classes table is already populated.
What I want to do is insert a new row into char_active using the name and classID column, and have the HP column auto populate based on the corresponding value in the classes table. This is the trigger I wrote but I'm getting the error
Incorrect syntax near 'inserted'.
I'm new to sql, this is actually the first trigger I've tried writing.Â
create trigger new_hp on curr_chars.char_active instead of insert as declare @hp tinyint select @hp=lists.classes.hp from lists.classes where lists.classes.classID=inserted.classID insert into curr_chars.char_active (name, classID, hp) inserted.name, inserted.classID, @hp go
I'm hoping someone can help with with a task I've been given. I need to write a trigger which will act effectively as a method of automatically distributing of incoming call ticket records. See DDL below for creation of the Assignment table, which holds information on the call ticket workload.
SELECT COUNT(CallID) AS [Total Calls], AssignmentGroup, Assignee FROM #Assignment GROUP BY AssignmentGroup, Assignee ORDER BY COUNT(CallID) DESC , AssignmentGroup, Assignee
What I need to do is write a trigger for on INSERT to automatically update the Assignee column with the name of the person who currently has the least active calls. For example, using the data above, the next PC Support call will go to Mickey Mouse, and the next two Service Desk calls will go to Jim Smith.
So, the logic for the trigger would be
UPDATE #Assignment SET Assignee = (SELECT Assignee FROM #Assignment WHERE COUNT(CallID) = MIN(COUNT(CallID))
But that's only the logic, and obviously it doesn't work with the syntax being nothing like correct.
Does any one have an idea or pointers as to how I should go about this?
Hi I am having a problem in auditing the column data in tables.My requirement is i have write a trigger which is capable of auditing the columns which are going to be added in the future also with out using dynamic SQL.is there any way to do so. I feel if i can get the column data based on ordinal position then it is possible. Can any body suggest. My set Up is like this I have a base_table to be audited. I have a Audit_spec table which contains name of the table and columns to be audited. And Audit table which actually captures the table name,column name ,old value and new value. I have to audit only those columns in the Audit_spec spec. If schema changes(Like new column added) happens to base_table and I want that column to be audited.with out any changes to my trigger code i should handle the newly added column ..
The report runs but I get a "#ERROR" when I place the field on the report.
I next tried creating a new column with the SQL statement:
SELECT Project.ProjectCode AS PC, Project.StatusCode AS SC, Time.StandardHours AS Hours, Time.StandardChargeAmt AS StdAmt, Time.TaskUID as UID, Time.StandardChargeRate as Rate, ChargeableFlag, 'Bill' =
Case When TaskRule.ChargeableFlag = 0 Then 'Non-Bill' When TaskRule.ChargeableFlag = 1 Then 'Billable'
[Code] .....
This query, less the case statement for BLAmt creates the dataset for the SSRS. Adding the Case statement for the BLAmt produces the error: "Invalid column name 'Negamt'."
