Transact SQL :: Column Update With Comparison With Another Table
Nov 10, 2015
I upload data from a Txt File(Txt_Temp) where I have VinNumber with 6 digits. Another table name Resrve_Temp1 where I have Vinumber with 17 digit. Now I need to update the vinnumber 6 digit to 17 digit or to new column in Txt_temp.
Txt_Temp - Table
I tried this code with no succes and only one row is updating
update Txt_Temp Set Txt_Temp.Vinnumber=dbo.R_ResrvStock.Vin
from dbo.R_ResrvStock inner join Txt_Temp on Right (dbo.R_ResrvStock.Vin,6)=Txt_Temp.VinNumber
OR Add this code in view
Select dbo.R_ResrvStock.Vin,R_Txt_Temp.Vinnumber,R_Txt_Te mp.Model_Code
from dbo.R_ResrvStock inner join R_Txt_Temp on Right (dbo.R_ResrvStock.Vin,6)=R_Txt_Temp.VinNumber
Vin
123456
123123
123789
Resrve_Temp1 - Table

I am dynamically creating a job using sql script and it does work fine(It creates the job and when it's done it gets deleted as it's created dynamically. so I won't be having any job history at all in the system.). I want to update an existing table if the jobs fails and I am not sure how I can do that using t-sql script. Is that possible?I have an idea but not sure whether it works. In the job create script, can I include the code for if the job fails then go to step 2 and update the table column with the error??? If so, how can I retrieve the error???

I am trying to build a DIM table using a source table that has the following setup...
CREATE TABLE [dbo].[APPL_STATUSES](
[APPLICATIONS_ID] [varchar](10) NOT NULL,
[POS] [decimal](10, 0) NOT NULL,
[APPL_STATUS] [varchar](5) NULL,
[APPL_STATUS_DATE] [datetime] NULL,
[APPL_APPLICANT] [varchar](10) NULL)
GO
[code]....
What I am trying to do is to break out the APPL_STATUS_DATE into a STATUS_START_DATE and an STATUS_END_DATE in a new table. I also need to be able to update the STATUS_END_DATE based on the previous day's date. Like so...
CREATE TABLE [dbo].[APPL_APPLICANT_STATUSES](
[APPLICATIONS_ID] [varchar](10) NOT NULL,
[POS] [decimal](10, 0) NOT NULL,
[APPL_STATUS] [varchar](5) NULL,
[STATUS_START_DATE] [datetime] NULL,
[STATUS_END_DATE] [datetime] NULL,
[APPL_APPLICANT] [varchar](10) NULL)
GO
[code]...

how to achieve this in SQL query, i cannot use CTE or temp table as i need to use this code in another tool, it has to be single query, can use subquery or join would be better.

Is there a transform available which allows you to specify two different tables (same primary key) and compare columns (you identify which column(s) values need to be compared in the transform) between those two tables?
thanks

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

I have a table that has two columns. One column has ID from 1 to 1800. The other column is null. I want to update the second column with values from 29 to 43. So for ID 1, value will be 29, ID value will 30 and it goes to 43. Then after it will start from 29 again and goes to 43. It goes all the way to the highest ID, i.e. 1800.I have added a script for better clarity
declare @t table (stuID int, valueID int)
insert into @t (stuID, valueID)
values (1,null), (2,null), (3,null), (4,null)
the null part is what I want to have from 29 to 43 .... all the way untill the ID reachs to 1800

I have a column with XML data stored in it. I need to update that column several times with new values for different nodes. I've written a CLR function to update the XML quickly but the update is always based on the initial value of the xmlData column. I was hoping that the subsequent updates would be based on the new data from the prior update (each xmlTable has several newData rows). Do I have to make this a table valued function and use cross apply?
UPDATE xmlTable
SET xmlTable.xmlData = Underwriting.UpdateByDynamicValue(xmlTable.xmlData,newData.NodeID,newData.NewValue)
FROM xmlTable
JOIN newData
ON xmlTable.ID = newData.fkXmlTableID

Below is the resultset I got using the following SQL statement
SELECT ROW_NUMBER() OVER (PARTITION BY ID ORDER BY create_date DESC) AS RowNum
,ID

Resultset:
RowNum ID
create_date end_date
1 0001
2015-02-18 NULL
2 0001
2014-04-28 NULL
[Code] ....
Now, I want to update the end_date column with the create_date's values for the next row_number. Desired output is shown below:
RowNum ID
create_date end_date
1 0001
2015-02-18 NULL
2 0001

I have a table with ~30M records. I'm trying to add a column to the existing table with default value and have noticed following ... When using alter with default value- (Executes more than 45 min and killed forcefully)
ex:
ALTER TABLE dbo.Table_X Add is_Active BIT CONSTRAINT DF_Table_X_is_Active DEFAULT 'FALSE' NOT NULL
GO
When using update command after adding column with alter (without default value) it completes is 5 min.
ex:
ALTER TABLE dbo.Table_X Add is_Active BIT NULL
GO
UPDATE Table_X SET is_Active = 0 WHERE is_Active IS NULL
GO
Why there is so much of difference in execution times ? I was just trying to understand internal behavior of the SQL in these two scenarios.

My current proc updates(updates using joins of two or three tables) millions of records as per the condition provided for each department.
However, when the proc fails it writes to a ErrorTable, ERROR_MESSAGE(), ERROR_SEVERITY() and which department has failed.
Since the records are updated keeping the selected departments in loop, I get the department in a temp variable.Now, I was asked to log the specific record where the failure was occured.Something like log the identity column value or primary key value which record has failed.

Our dev team wants to introduce a complex key, which is made up of
EventDate datetime2(5) = ‘2015-10-22 10:19:59.12345’
ConsumerID bigint = 1234
SiteID tinyint = 15
EventDate will be converted to a bigint and then to a hex value
= 2015-10-22 10:19:59.12345 = 2015102210195912345 = 1BF714C8A0D4F699
ConsumerID will be converted to a hex value
= 1234 = 4D2
SiteID will be converted to a hex value
= 15 = F
The hex values will then be concatenated together and stored as a string (varchar). The application will handle the creation of the complex key
= ‘1BF714C8A0D4F699-4D2-F’
I am trying to argue against this approach and get them to store the values in their native form, in separate columns as a natural key.
To make matters worse, we need to use partitioning, where the partition boundary will be on a hexed datetime2(5) at weekly intervals. I was really hoping a proof of concept would show that hex string comparison could potentially put a row under a wrong partition, but so far, on an 8 million rowset, it is working fine.
For example, in the proof of concept, right partition boundary:
= '1BF398D53DFA1800'
(2014-12-15 00:00:00.00000)
contains rows
= '1BF3983242B9C000-1-2'
(2014-12-08 00:00:00.00000-1-2)
Through to
= '1BF398C373960580-2FAF3003-2'
(2014-12-14 23：59：00.00000-800010243-2）
The prior partition boundary is 1
= 'BF3983242B9C000'
(2014-12-08 00:00:00.00000)
How is this working, given that the string lengths (varchar) are different and the row value contains dashes and the partition boundaries are smaller in length without dashes? How varchar string comparison is working here?

I've got a table with 6 fields :
EmployeeAccess
(MasterID, LoginID, AccessID, Storage1, Storage2, Storage3)
that needs to be updated using the data in the following spreadsheet
NewEmployeeAccessData
(ID, MasterID, AccessID1, LoginID1)
There is a 1:1 relationship between the two tables..I'm trying to code a pair of update statements on the EmployeeAccess table (1 for LoginID, 1 for AccessID) with the following logic:
If LoginID is NULL, then Update LoginID with new LoginID1 value,
If LoginID is not null, and Storage1 is NULL then Update Storage1 with New LoginID1 values
If LoginID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New LoginID1 values
etc etc...
The same applies when trying to populate the AccessID column
If AccessID is NULL, then Update AccessID with new AccessID1 value,
If AccessID is not null, and Storage1 is NULL then Update Storage1 with New AccessID1 values
If AccessID is not null, and Storage1 is not NULL and Storage2 is NULL then Update Storage2 with New AccessID1 values
etc etc.
I have no control over the schema of this table so I'm trying to work the logic on how to update the columns in my table only if the corresponding column data is NULL, else update the next non NULL Storage column.

I would like to update the flag of the promotion ID should the promotion ID date range overlap with Promotion ID(All) Date Range. The general logic is as below.
Update TableName
SET PromotionID Flag = 1 AND Reason = 'Overlap with row ID(Overlap row ID number)'
Where EACH ROW(Except with Promotion ID ALL) Date Range Overlap with ROW(with promotion ID ALL) Date range
Note: ROW is Partition By ColumnA,ColumnB
TableName: PromotionList
ID PromotionID StartDate EndDate ColumnA ColumnB Flag Reason
1 1 2015-04-05 2015-05-28 NULL NULL 0 NULL
2 1 2015-04-05 2015-04-23 2 3 0 NULL
3 2 2015-05-04 2015-07-07 2 3 0 NULL

6 1 2015-02-03 2015-03-03 NULL NULL 0 NULL
Expected outcome after performing update on the table
ID PromotionID StartDate EndDate ColumnA ColumnB Flag Reason
1 1 2015-04-05 2015-05-28 NULL NULL 1 Overlap with row ID 4

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
