Transact SQL :: How To Fetch Only Latest Address

May 10, 2015

Got a Table_A in the form of:
Cust_ID
Cust_Name
and another Table_B as:
Recording_Date
Invoice_ID
Cust_ID
Cust_Address

In such a case let's say I need a View to represent the columns:

Cust_ID (From Table_A)
Cust_Name (From Table_A)
Cust_Address (From Table_B)

However, with the Customers changing their addresses and having multiple records of different dates in Table_B how to reflect the Latest address of the same in the requisite View?In other words Cust_Id (AB), Cust_Name (CD), who as per Table_B have 100 records with three different addresses (EF, GH & IJ) spread over two years. How to fetch the only latest address in this case? i.e. a record in View_C as:

Cust_ID
Cust_Name
Cast_Address

AB
CD
IJ

SQL Server 2012 :: Delete / Recreate Identity Column / Fetch Newly Created Values In Update Statement?

Jul 25, 2015

I have a four tables called plandescription, plandetail and analysisdetail. The table plandescription has the columns DetailQuestionID which is the primary and identity column and a QuestionDescription column.

The table plandetail consists of the column PlanDetailID which the primary and identity column, DetailQuestionID which is the foreign key attribute of plandescription table and a planID column.

The third table analysisdetail consists of a analysisID which the primary and identity column, PlanDetailID which is the foreign key attribute of plandetail table and a scenario.

Below is the schema of the three tables

I have a two web form that will insert, update and delete data into these three tables in a two transaction. One web form will perform CRUD operations in plandescription and plandetail table. When the user inserts QuestionDescription and planid in this web form, I will insert the QuestionDescription Value in the plandescription table and will generate a DetailQuestionID value and this value is fed to the plandetail table with the planid. Here I will generate a PlanDetailID.

Once this transaction is done, I will show the second web form in which the user enters the scenario and this will be mapped with the plandescription using the PlanDetailID.

This schema cannot be changes as this is the client requirement. When I insert values I don’t have any problem. However when I update existing data, I need to delete existing PlanDetailID in the plandetail table and recreate PlanDetailID data for that DetailQuestionID and planID. This is because, the user will be adding or deleting a planID associated with the QuestionDescription.

Once I recreate PlanDetailID for that DetailQuestionID and planID, I need to update the old PlanDetailID with the new PlanDetailID in the third table analysisdetail for the associated analysisID.

I created a #Temp table called #DetailTable to insert the values analysisID, planid and old PlanDetailID and new PlanDetailID so that I can have them in update statement once I delete the data from plandetail table for that PlanDetailID.

Then I deleted the plandetailid from the plandetail table and recreate PlanDetailID for that DetailQuestionID. During my recreation I fetched the new PlanDetailID’s created into another temp table called #InsertedRows

After this I am running a while loop to update the temp table #DetailTable with the newly created PlanDetailID for the appropriate planID’s. The problem is here. When I have the same number of planID’s for example 2 planID’s 1,2 I will have only two old PlanDetailID and new PlanDetailID for that planID and analysisID.But When I add a new PlanID or remove a existing planID I am getting null value for that newly added or deleted planID. This is affecting my update statement of analysisdetail table as PlanDetailID cannot be null.

I tried to remove the Null value from the #DetailTable by running the update statement of analysis detail in a while loop however its not working.

DECLARE @categoryid INT = 8
DECLARE @DetailQuestionID INT = 1380
/*------- I need the query to run for the below three data.
Here i'm updating my planids that already exists in my database*/
DECLARE @planids VARCHAR(MAX) = '2,4,5'

Integration Services :: SSIS Package - Replacing Null Values In One Column With Values From Another Column

Sep 3, 2015

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.

Integration Services :: Fetch Data From Netezza Database Based On Values Present In Excel Using SSIS

Aug 7, 2015

I have an excel sheet containing one column (ID_NO) with 400K rows. I have a database from where I have to fetch some other columns from a Netezza database. Initially I tried hardcoding all the 400K rows in the query that I wrote using filter WHERE ID IN ('1212','2334'). But after pasting all the 400K rows the query is running indefinitely.

I have imported all the ID in a SQL table (MY_LIST table). I used a DFT, and selected ODBC source, and selected my netezza server. Then in the 'Data access mode' I selected the SQL command from the dropdown.I pasted the same query that I wrote in Netezza. Is there any way to pull only for those records that I have pulled in my SQL table (MY_LIST) ?

How To Fetch Data Before Inserting A New ROW If We Are Using Identity Column??????

Apr 21, 2008

Hi,

I am using SQL Server 2005 Mobile Edition & Merge Replication

in this I want to insert a record into table,
in that table I have taken UserID coloumn as auto incrementing Identity type.

In a book I read that,
If you are using an Identity column, you must find the next available number and reseed before an insert can be successful. You will also have to set up ranged identity columns on the published database to prevent errors when the new data is merged.

Now I want to ask here that, how should I ressed that value before inserting?????

any help in a form of CODe will be appriciated.....

thanks in advance...

Analysis :: Bitmask Column Values As Dimension Values

Jun 18, 2015

Bitmask fields! I am capturing row changes manually via a high frequency ETL task.  It works effectively however i am capturing the movement of multiple fields.  A simple example, for Order lines, i have a price, a discount and a date.  I am capturing a 001, 010, 100 respectively for each change.  

I would like my users to be able to select from a dimension which has the 3 members in it and they can select one, multiples, or all values (i.e. only want to see rows that have had the date and price changed). 

Obviously if i only had 3 columns i would use bit's and be done with it, i have many different values (currently around 24 and growing).

Transact SQL :: Selecting Latest Date But Over Another Date Column Including Nulls?

Nov 26, 2015

CREATE TABLE #Dateissue
(ID int,
Code nvarchar (20),
Datein datetime,
Declined datetime )

[Code] .....

I have a table here.  I want  find a way of getting the latest date, when the code is the same.  If the Declined date is null.  Then I still want the latest date.  E.g. ID 3.  

If the declined date is filled in.  Then I want to get the row, when the Datein column value is greater then the declined date only.

I tried grouping it by max date, but   i got an error message when trying this out.  Against the code  

WHERE MAX(Datein) > Declined

An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference.  What do I need to do to get both my outputs working?

Transact SQL :: Convert Certain Row Values To Next Column Values

Jul 9, 2015

I have a table with 2 columns and my source data looks like this..

PolicyNum   InsCode    

1ABC12          1001        
1ABC12          1002        
1ABC12          1003       
1ABC12          1004       
1ABC12          1005        

[Code] ....

My output should look like this..I need T-sql to get below output.

PolicyNum   InsCode1   InsCode2    

1ABC12             1001       1005       
1ABC12             1002       1006        
1ABC12             1003       1004       
1ABC20             1001       1005        

[Code] ...

Basically it's converting certain row values to new column. Every PloicyNum will have 1001 to 1006 Fixed InsCode values as a group.

Rule-1: InsCode value 1001 should always mapped to 1005   
            InsCode value 1002 should always mapped to 1006
            InsCode value 1003 should always mapped to 1004 

Rule-2: For a policyNum, If any Inscode value is missed from the group values 1001 to 1006, still need to mapped with corresponding values as shown in Rule-1

In the above sample data..

for PolicyNum - 1ABC20 , group values 1003,1006 are missing
for PolicyNum - 1ABC25 , group values 1002,1003,1004,1005,1006 are missing

Create Table sampleDate (PolicyNum varchar(10) not null, InsCode Varchar(4) not null)
Insert into Sample Date(PolicyNum, InsCode) Values ('1ABC12','1001')        

Insert into Sample Date(PolicyNum, InsCode) Values ('1ABC12','1002')       
Insert into Sample Date(PolicyNum, InsCode) Values ('1ABC12','1003')

Column Defaults As Parameters And/or Column Values

Jan 7, 2008

Good afternoon,

I am trying to figure out a way to use a columns default value when using a stored procedure to insert a new row into a table. I know you are thinking "that is what the default value is for", but bare with me on this.

Take the following table and subsequent stored procedure. In the table below, I have four columns, one of which is NOT NULL and has a default value set for that column.

CREATE TABLE [dbo].[TestTable](
[FirstName] [nvarchar](50) NULL,
[LastName] [nvarchar](50) NULL,
[SSN] [nvarchar](15) NULL,
[IsGeek] [bit] NOT NULL CONSTRAINT [DF_TestTable_IsGeek] DEFAULT ((1))
) ON [PRIMARY]

I then created the following stored procedure:

CREATE PROCEDURE TestTable_Insert
@FirstName nvarchar(50),
@LastName nvarchar(50),
@SSN nvarchar(15),
@geek bit = NULL
AS
BEGIN
INSERT INTO TestTable (FirstName, LastName, SSN, IsGeek)
VALUEs (@FirstName, @LastName, @SSN, @geek)
END
GO

and executed it as follows (without passing the @geek parameter value)

EXEC TestTable_Insert 'scott', 'klein', '555-55-5555'

The error I got back (and somewhat expected) is the following:


Cannot insert the value NULL into column 'IsGeek', table 'ScottTest.dbo.TestTable'; column does not allow nulls. INSERT fails.

What I would like to happen is for the table to use the columns default value and not the NULL value if I don't pass a parameter for @geek. OR, it would be really cool to be able to do something like this:

INSERT INTO TestTable (FirstName, LastName, SSN, IsGeek)
VALUEs (@FirstName, @LastName, @SSN, ISNULL(@geek, DEFAULT))


Does this make sense?

I have 2 tables in a database. Table 1 is Parts and Table 2 is MiniParts. I need a script that adds a new column in the MiniParts table. and then populate the new column (NewMinipartsCL) based on Values that exist in the PartsNum column in the Parts Table, and MiniPartsCL column in the MiniParts columns.

The new column is NewMiniPartsCL. The table above shows the values that the new column (NewMiniPartsCL) should contain.

For Example
Anytime you have "1" in the PartsNum column of the Parts Table and the MiniPartsCL column of the MiniParts Table has a "K" , the NewMiniPartsCL column in the MiniParts Table should be populated with "DK" ( as shown in the table above).

Anytime you have "1" in the PartsNum column of the Parts Table and the MiniPartsCL column of the MiniParts Table has a "K" , the NewMiniPartsCL column in the MiniParts Table should be populated with "K" ( as shown in the table above). etc..

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,

Beli

Sum Of Column Values Of Each Row In Another Column Of Same Table

Feb 12, 2006

Hi,
I have got a table where i want to display sum of count(Column1), count(Column2) in another column.How can this be done?
for example
SELECT SUM(Count(pxInsName)+Count(pxFlowName)) AS "pySummaryCount(1)" , Count(pxInsName) AS "pySummaryCount(2)" , Count(pxFlowName) AS "pySummaryCount(3)" , pxAssignedOrg AS "pxAssignedOrg" , pxAssignedOrgDiv AS "pxAssignedOrgDiv" , pxAssignedOrgUnit AS "pxAssignedOrgUnit" FROM pc_assign_worklist WHERE pxObjClass = ? GROUP BY pxAssignedOrg , pxAssignedOrgDiv , pxAssignedOrgUnit ORDER BY 'pySummaryCount(1)' DESC

But sum function can not be used on aggregate function.

Is there any other way.

Combining Column Values Into One Column

Oct 30, 2007

Hi Folks, Im new to SQL, and I am trying to do the following:

I have a table Documents with DocID, Path and FileName.
A second table Keywords has KwdID, KeywordString
A third table DocumentKeywords links the two with DocID,KwdID. Multiple keywords are linked to one document.

I want to create a SELECT query that makes a result table that contains Path, FileName and Keywords columns where the Keywords column contains entries like "Keyword1,Keyword2,Keyword3" ie. a comma delimited list of keyword strings which have been built from the keywords that associate with a specific document.

I found a nice sample here
http://www.sqlteam.com/article/using-coalesce-to-build-comma-delimited-string
which shows how to return just the comma delimited string itself:

DECLARE @List varchar(100)

SELECT @List = COALESCE(@List + ', ', '') + Keywords.KeywordString
FROM DocumentKeywords
WHERE KwdID = 1

SELECT @List


I cannot seem to integrate this into the query so that it calculates the string for each row on the fly. My suspicion is that the capability is there. Can somebody point me in the right direction?

Thanks
