I need to update the below dates for multiple records in a table. Each record has a unique Id call object_id. I have used the below SQL to update one record but would like to know if I can bulk update them. I constantly receive these requests to update the date. This time it is only 6 records but usually, I get the request to update even 50 records.
This is the data that I received
This is the data in the database table.
I need to update the CASE_DETAIL table by adding the judgment date into JUDGMENT_DATE COLUMN which is currently null.
update case_detail cd set CD.JUDGMENT_DATE = '18/DEC/1998' where CD.OBJECT_ID = 5091449
Any advice in the direction of creating a SQL script that would bulk update the date column in multiple records would be of great assistance.
If your new values are arriving in a table, you can update the case_detail table by doing:
update case_detail cd
set judgment_date = (select r.judgement_date
from received r
where cd.object_id = r.object_id
)
where exists (select 1
from received r
where cd.object_id = r.object_id
);
Please try this.
UPDATE case_detail cd SET CD.JUDGMENT_DATE = '18/DEC/1998' WHERE CD.OBJECT_ID IN (SELECT OBJECT_ID FROM #ReceivetableName) AND CD.JUDGMENT_DATE IS NULL

I am creating After Insert trigger , its working fine, but I have certain conditions before executing the statements inside the trigger
Based on Different CustomerId Run the trigger, I want check which CustomerId got inserted in my LoyaltyDetailsTable, say if last insert
was Customerid=2 then pass that Customerid in where condition then run
the trigger , or if Customerid = 1 then run the trigger for that Id,
so on.
I want to check whether in PriceClaimTable the inserted CustomerId exist or not, If exists then update the details else just insert the
values in LoyaltyDetailsTable only.
Trigger query
CREATE TRIGGER DetailsAfterInsert ON [dbo].[LoyaltyDetailsTable]
FOR INSERT
as
UPDATE PriceClaimTable
SET CurrentPoints =
(
(SELECT SUM(LoayaltyPointsTable.Points) AS RecentPoints FROM LoayaltyPointsTable
join LoyaltyDetailsTable ON LoayaltyPointsTable.LoyaltyPointsId
= LoyaltyDetailsTable.LoyaltyPointsId
WHERE CustomerId=1 and LoyaltyDetailsId= (SELECT MAX(LoyaltyDetailsId)
AS LoyaltyDetailsTable FROM LoyaltyDetailsTable))
+
(SELECT CurrentPoints FROM PriceClaimTable WHERE ClaimCustomerId=1 and
PriceClaimId=(SELECT max(PriceClaimId) FROM PriceClaimTable
))
)
WHERE ClaimCustomerId=1 and PriceClaimId=(SELECT max(PriceClaimId) FROM PriceClaimTable)
This is my first attempt to write a trigger, and here is table structure.
Any help would be great.
What you're looking for here is the inserted table. Every time you issue an UPDATE statement, SQL Server generates two virtual tables called inserted and deleted that store information on the data modifications you're making. These tables are accessible from your trigger. For more information, see here: https://msdn.microsoft.com/en-us/library/ms191300.aspx
You can use inserted to get the IDs you're looking for. So, instead of:
WHERE ClaimCustomerId=1
you can use:
WHERE ClaimCustomerId=inserted.ClaimCustomerId
this query is working fine.
UPDATE data
SET unit_id='a3110a89'
WHERE unit_id='7d18289f';
Now, I need to run this query over 30 times
so I made csv file import it to the DB with this command:
COPY mytable FROM 'D:/test.csv' WITH CSV HEADER DELIMITER AS ','
Now I have table called my table with 2 columns OLD and NEW
i want to search the table "data" in column unit_id anywhere there if the value equals to the value in table "mytable.old" replace it with the value "mytable.new" on the same row.
I tried to run this query but I get an error:
UPDATE data
SET unit_id=(SELECT mytable."old" FROM public.mytable)
WHERE unit_id=(SELECT mytable."new" FROM public.mytable)
error:
more than one row returned by a subquery used as an expression
I think i'm just trying to do it in the wrong way...
thx for the help!
by the way Im using PostgreSQL
Your subqueries need to be correlated to the outer update:
UPDATE data
SET unit_id = (SELECT mytable."new" FROM public.mytable where data.old = mytable.old)
WHERE unit_id in (SELECT mytable."old" FROM public.mytable);
That is, set the unit_id to the "new" value, when you find the "old" value in the table.
Can you try like this,
UPDATE data A
SET A.unit_id=B.old
FROM (SELECT mytable."old",mytable."new" FROM public.mytable) B
WHERE A.unit_id=B.new
UPDATE data A
SET unit_id = B."old"
FROM public.mytable B
WHERE A.unit_id = B."new"
;
BTW: it looks like you also have old and new swapped in your question. Do you really want A's value to be set to B's old field?
I have a list of items that I need to update based on their unique ID in a SQL Server 2005 environment. I was wondering what the best way of writing a script to update these items.
I know I can simply update a column by writing multiple queries such as:
UPDATE myTable
SET HelpLink = 'newLink'
WHERE ID = 5
UPDATE myTable
SET HelpLink = 'newLink2'
WHERE ID = 6
Is there any other way of doing this without having to repeat the above update about 20 times? Repeating the above tends to make a pretty ugly update script.
NOTE: I have a bulk set of items that I will be updating by their unique ID, these items are not coming from a database table.
I found out that you can use case statements which seems to simplify things quite a bit. This allows me to add multiple items into a single query.
UPDATE [MyTable]
SET HelpLink = CASE ID
WHEN 2 THEN 'MKSDefectsChart.png'
WHEN 6 THEN 'EPMRisks.png'
WHEN 7 THEN 'DCTSHardwareChanges.png'
ELSE NULL
END
WHERE ID IN (2, 6, 7)
You can always update from another table like
update myTable
set HelpLink = myOtherTable.HelpLink
from myOtherTable
where myTable.[ID] = myOtherTable.[ID]
You'll have to create that other table though
I have a table that looks like the below table:
Every time the user loan a book a new record is inserted.
The data in this table is derived or taken from another table which has no dates.
I need to update this tables based on the records in the other table: Meaning I only need to update this table based on what changes.
Example: Lets say the user return the book Starship Troopers and the book return is indicated to Yes.
How do I update just that column?
What I have tried:
I tried using the MERGE Statement but it works only with unique rows of data, meaning you get an error if the same ID appears more than once.
I also tried using a basic UPDATE Statement and a JOIN but that's not going well.
I am asking because I have ran out of ideas.
Thanks for reading
If you need to update BooksReturn in target table based on the same column in source table
UPDATE t
SET t.booksreturn = s.booksreturn
FROM target t JOIN source s
ON t.userid = s.userid
AND t.booksloaned = s.booksloaned
Here is SQLFiddle demo
You can do this by simple Update & Insert statement.....
Two table A & B
From B you want to insert data into A if not exists other wise Update that data....
,First Insert into temp table....
SELECT *
INTO #MYTEMP
FROM B
WHERE BOOKSLOANED NOT IN (SELECT BOOKSLOANED
FROM A)
,Second Check data and insert into A.
INSERT INTO A
SELECT *
FROM #MYTEMP
And at last write one simple update statement which update all data of A. If any change then it also reflect to that data otherwise data as it is.
You can also update from #MYTEMP table.
This is my first time using triggers.
My trigger is not being triggered please help.
CREATE TRIGGER sbhack_autoban
ON LOG_CONNECT201211
FOR INSERT
AS
BEGIN
/* query to run if single or multiple data is
inserted into LOG_CONNECT201211 table */
UPDATE login.dbo.USER_CHECK_LOGIN
SET login.dbo.USER_CHECK_LOGIN.CHECKLOGIN = 2
WHERE login.dbo.USER_CHECK_LOGIN.USER_KEY IN
(SELECT e.USER_KEY
FROM game.dbo.CHAR_DATA0 AS e
INNER JOIN gamelogs.dbo.LOG_USING_DEPOT201211 AS p
ON e.CHAR_KEY = p.CHAR_KEY
WHERE p.GATENUM = 150)
AND login.dbo.USER_CHECK_LOGIN.CHECKLOGIN = 0
AND login.dbo.USER_CHECK_LOGIN.USER_KEY != 51;
END
This is suppose to run the query inside the BEGIN : END if an entry is inserted into the LOG_CONNECT201211 table. But nothing is happening even when I have inserted multiple data into LOG_CONNECT201211.
When your INSERT trigger fires - then at least one new row has been inserted! That's a fact.
Now the question is: given that a single or multiple new rows have been inserted - what do you want to do with this knowledge??
Typically, you could e.g. set a column to a value you cannot specify as a default constraint - or you could insert the fact that the row has been inserted into an audit table or something....
So you'd have something like this:
CREATE TRIGGER sbhack_autoban
ON LOG_CONNECT201211
FOR INSERT
AS
INSERT INTO LogAudit(InsertedDate, UserKey)
SELECT
GETDATE(), i.User_Key
FROM
Inserted i
or something like that....
Update: ok, so you want to run that UPDATE statement when the rows have been inserted - not 100% clear, what columns/values from the inserted rows you want to use - looks like the e.UserKey column only - correct?
Then the UPDATE would be:
UPDATE login.dbo.USER_CHECK_LOGIN
SET login.dbo.USER_CHECK_LOGIN.CHECKLOGIN = 2
WHERE
login.dbo.USER_CHECK_LOGIN.USER_KEY IN
(SELECT USER_KEY FROM Inserted)
AND login.dbo.USER_CHECK_LOGIN.CHECKLOGIN = 0
AND login.dbo.USER_CHECK_LOGIN.USER_KEY != 51;
Update #2:
The point I still don't understand is : why do you want to run an update that uses the USER_CHECK_LOGIN, CHAR_DATA0 and LOG_USING_DEPOT201211 tables, when some rows are getting inserted into a totally separate, unrelated table LOG_CONNECT201211 ??
A trigger is used when you want to do something because rows have been inserted into that table - but in that case, you typically want to do something with the rows and their values that have been inserted...
I just don't see any connection between the rows being inserted into LOG_CONNECT201211 event, and the tables you are then querying from and updating. Where's the link?? WHY do you need to run *this UPDATE when data is inserted into LOG_CONNECT201211 ?? It would make sense if data where inserted into one of the tables involved in the UPDATE - but like this, it just totally doesn't make any sense .....
