Transact SQL :: Detecting Modified Rows Before Writing To A Table?
Apr 17, 2015
I've a table with more columns and 1 identifier. I need to write this table when a modified row is detecting respect to the columns not to the identifier.
So I've created a temporary table to put the potential rows to write on the real table, but I want to detect the modified rows. I've thought to use the checksum function, but I don't know how to use it and if it could be useful in this scenario.
Moreover, in the temporary table I've collected daily the rows to write: the first day a row could have a value respect to his columns, the next day a different value and the next one the same value respect to the first day.

Hello,I have 2 tables, Table1 and Table2. I have copied all data from Table1to Table2.However Table1 is dynamic it has new rows added and some old rowsmodified everyday or every other day...How can I continue to keep Table2 up to date without always having tocopy everything from Table1?Basically from now on I would only like to copy new rows or modifiedrows in Table1 to Table2 and skip rows that are already present andhave not been modified in Table1. I would like to not do anything forany rows that were removed in Table1 and continue to keep a copy ofthem in Table2.Is using a DTS package the best way to automate this update of Table2to make sure Table2 is always up-to-date with Table1?Thanks for any help or advise :-)Yas

I have a question regarding the total count of the table rows
Select count (name) from test. Lets say I have got 200 count. And Select count (lastname) from test1.I have got 200.And this counts I should store it in "There are nn name items awaiting your attention and nn pending lastname's awaiting your approval".
So now I have to store the count in 'nn'.

mobno varchar(10)
)
INSERT INTO @tmpTable(name,address1,phnno,mobno)

I want to remove all empty rows like row 1,2 and 3 in the above example.
I can't check all columns null values as there are many columns in my actual table.

I have a table with more than 1000 records. The columns look like this
Import id | Reference | Date | Username | Filename
Some of the rows are duplicates except for the fact that they have different values for the first column alone (import id)
11111 test 21-07-2015 xxxxxx yyyyyy
22222 test 21-07-2015 xxxxxx yyyyyy
Is it possible to delete these kind of duplicate rows by ignoring the import id ?

Copy out all data from a DB table into/across delimited text file(s) ensuring that each text file size is no more than 3MB.Have created a SSIS solution where it achieves this requirement ..well sort of achieves the requirement ... Here it what the current solution (sparing the minute details) does in a nutshell & Problems with it:
1) Created a function (Script below) which finds the
maximum row size in bytes in a given DB table & uses it to calculate
how many rows can be copied out into a text file without exceeding 3MB size limit.
For instance: A DB table selected had 788 rows in total and this function for this particular table returned a value of 181 rows { select [dbo].[udf_GetRowPartitionNumber](‘<TableName>’)as #ofRowstoPartitionTableby --181} meaning in order to not exceed the requirement of 3MB per text file, we had to copy all the data from DB table across (create) 5 text files {Select
CEILING(788

I have added a new column to a table, but it is not showing up in the column mapping tab of the lookup editor.
It does show up in the preview.
Without deleting and recreating the component (with all the ensuing broken metadata fixes 'downstream' that this always entails), how can I get it to recognise the change?
In future I will do all LUs as a sql statement so at least I can control columns. This again defeats the purpose of the drag and drop environment..... If it were a harry potter character, it would be a dementor

I want to iterate through the table and populate Address1 as [Block] [Street] #[Floor]-[Unit].If the 'Floor' field contain a number < 10 (e.g., '8'), I want to add a '0' before it (e.g., '08'). Same for Unit.How would I do this using cursors (or other recommended method)?

This question is extension from the topic Updating table Rows with overlapping dates: [URL] .....
I am actually having a table as following:
Table Name: PromotionList
Note that the NULL in endDate means no end date or infinite end date.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-28 0
2 1 2015-04-23 NULL 0
3 2 2015-03-03 2015-05-04 0
4 1 2015-04-23 2015-05-29 0
5 1 2015-01-01 2015-02-02 0
And I would like to produce the following outcome to the same table (using update statement): As what you all observe, it merge all overlapping dates based on same promotion ID by taking the minimum start date and maximum end date. Only the first row of overlapping date is updated to the desired value and the flag value change to 1. For other overlapping value, it will be set to NULL and the flag becomes 2.
Flag = 1, success merge row. Flag = 2, fail row
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 NULL 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
The second part that I would like to acheive is based on the first table as well. However, this time I would like to merge the date which results in the minimum start date and End Date of the last overlapping rows. Since the End date of the last overlapping rows of promotion ID 1 is row with ID 4 with End Date 2015-05-29, the table will result as follow after update.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-29 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
Note that above is just sample Data. Actual data might contain thousands of records and hopefully it can be done in single update statement.
Extending from the above question, now two extra columns has been added to the table, which is ShouldDelete and PromotionCategoryID respectively.
Original table:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 2015-05-28 0 Y 1
2 1 2015-04-23 2015-05-29 0 NULL NULL
3 2 2015-03-03 2015-05-04 0 N NULL
4 1 2015-04-23 NULL 0 Y 1
5 1 2015-01-01 2015-02-02 0 NULL NULL
Should Delete can take Y, N and NULL
PromotionCategoryID can take any integer and NULL
Now it should be partition according with promotionid, shoulddelete and promotioncategoryID (these 3 should be same).
By taking the min date and max date of the same group, the following table should be achieve after the table is updated.
Final outcome:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 NULL 1 Y 1
2 1 2015-04-23 2015-05-29 1 NULL NULL
3 2 2015-03-03 2015-05-04 1 N NULL
4 1 NULL NULL 2 Y 1
5 1 2015-01-01 2015-02-02 1 NULL NULL

I have been tasked with writing an update query to update a table with more than 150 million rows of data. Here are the table structures:
Source Tables :
OC
CREATE TABLE [dbo].[OC](
[OC] [nvarchar](255) NULL,
[DATE DEBUT] [date] NULL,
[DATE FIN] [date] NULL,
[Code Article] [nvarchar](255) NULL,
[INSERTION] [nvarchar](255) NULL,
[Code] ....
The update requirement is as follows:
DECLARE @Counter INT=0 --This causes the @@rowcount to be > 0
while @@rowcount>0
BEGIN
SET rowcount 10000
update r
set Comp=t.Comp
[Code] ....
The update took more than 48h and didn't terminate , how to accelerate it ?

Existing table structure is below:
Table name: Student
Columns in Student are below:
Student_Id
Subject_Id
Quarter
Col1
Col2
Combination of Student_Id, Subject_Id and Quarter columns is the primary key. One student can take one subject in a quarter. Now the new requirement is a student can take multiple subjects in a quarter. So need to add another table like below:
NEW table name: Student_Subject and
column are below:
Student_id
Subject_Id
Quarter1
All the above three columns combination is primary key.
After the new table Student_Subject created,
remove Subject_Id column
from Student table.
When the user clicks on a button after selecting multiple subjects and provide col1 and col2 data then one row gets inserted into Student table and multiple rows gets inserted into Student_Subject table.
Is there any other table design that satisfies one student can take multiple subjects in a quarter?

I have a temp table with the following columns and data
drop table #temp
create table #temp (id int,DLR_ID int,KPI_ID int,Brnd_ID int)
insert into #temp values (1,2343,34,2)
insert into #temp values (2,2343,34,2)
insert into #temp values (3,2343,34,2)
[Code]....
I use the rank function on that table and get the following results
select rank() over (order by DLR_ID,KPI_ID,BRND_ID ) Rown,* from #temp
I am interested only in Rown and Id columns. For each Rown number, I need to get the min(ID) in the second column and the duplicate ID should be in 3rd column as shown below.If i have 3 duplicate IDs , I should have 3 rows with 2nd column being the min(id) and 3rd column having one of the duplicate ids in ascending order(as shown in Rown=6)

We have control table which will be useful whether we need to start the job or not. If we are starting the Job we will make it to 1.
Below is the Table Structure.
Table Name IN_USE_FG
CUST_D 0
PROD_D 0
GEO_D 0
DATE_D 0
Now we have different packages for 4 tables data loading. These 4 packages will start at a time. Before going to load the data we have to make the Flag to 1 and after that we have to load it. Because of this we have written Update statement to update the Value to 1 in respective Package.
Now we are getting dead lock because we are using same table at a same time. Because we are updating different records.

In a t-sql 2012 sql update script listed below, it only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value of 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?
UPDATE LKC
SET LKC.combo = lockCombo2
FROM [LockerPopulation] A
JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number

I have a job which executes hourly.
Essentially:
Begin
Truncate table A
Insert into A
(Col1,
Col2,
Col3...
)
Select Value1,
Value2,
Value3...
From Table B
End
The insert operation query takes approximately 3.5 minutes to execute. What's occurring is the Table is immediately truncated, and there are no rows in the table for those 3.5 minutes.
How can I avoid having this gap - where there are no rows in the table for that period of time during the job execution ? The table could be locked, but that doesn't seem like the best solution.

I am using SQL SERVER 2008R2, not Denali, so I cannot use OFFSET FETCH Clause.
In my stored procedure, I am doing a SELECT INTO #tblTemp FROM... Working fine. This resultset is going to be used in an SSIS package which will generate a pipe-delimited .txt file... Working fine.
For recoverability sake, I am trying to throttle back on the commit chunks to 1000 rows per commit until there are no more rows. I am trying to avoid large rollbacks.
Q: Am I supposed to handle the transactions (begin/commit/rollback/end trans) when the records are being inserted into the temp table? Or when they are being selected form the temp table?
Q: Or can I handle this in my SSIS package for a flat file destination? I don't see option for a flat file destination like I do for an OLE DB Destination (like Rows per batch, Maximum insert commit size).

we can easily load a file into db tables. However, my main concern here is the number of columns in the file. A text file TEXT_1400.txt has 1400 columns. I am unable to load data to my db table using BCP or BULK INSERT commands, as maximum of 1024 columns are allowed per table in SQL Server 2008.
We can still go ahead and create ‘Wide Table’ (a special table that holds up to 30,000 columns. The maximum size of a wide table row is 8,019 bytes.). But when operating on wide table, BCP/BULK INSERT commands still fail. After few hours of scratching my head over BCP and BULK INSERT, I observed that while inserting BCP/BULK INSERT commands are unable to identify SPARSE columns and skip these columns, which disturbs column mapping and results in data conversion and trancation errors.
Is there any proper way to load this kind of files into the db table?

I have a Dataflow task with oledb source that is using SqlCommand to retrieve data and oledb destination to write the source output to a table. I have access to both the source and destination databases.
The problem is the destination component is not writing any rows to the destination table eventhough the Source component is returning rows (I can see them in the Preview and the source database table as well).
I'm using "Table/View Name from Variable" for destination.
The Package executes without any errors but there is no output.
Any ideas?
Thanks.

What is the most efficient way to write an SP to tackle all kinds of combinations here (where a user could give any search input).I know this must be fairly common to come across this situation.I have written an SP which will take in all the parameters and based on "IF" statements and using "LIKE" in SQL, this SP returns search results.But I wanted to know if there was more efficient ways of doing this, as you can imagine you might end up having several combinations of IF conditions.
