Hi,

I have expiry_date field. I am using nthis code to get expired this month list.

SQL

SELECT contracts.contract_id, contract_types.type_name, contracts.contract_name, contracts.supplier, contracts.contact_name, contracts.contact_number, contracts.expiry_date, contracts.reminder FROM contracts
JOIN contract_types ON contract_types.type_id = contracts.type
WHERE MONTH(contracts.expiry_date) = MONTH(NOW()) AND YEAR(contracts.expiry_date) = YEAR(NOW());

Now, I would like to get list of expiring next month. How can I do this? what if current month is 12? then Next Month will be 1 and Year will also be changed?

Kindly advise

This may be easier to read and you won't need to do calculations on years:

WHERE DATEDIFF(mm,contracts.expiry_date,DATE_ADD(NOW(), INTERVAL 1 MONTH)) = 1

Hm, depends on the details of his requirements.
If I see it correctly, your query will select all data within one month from now. His question looked like he needed the data of next calendar month.

Have a look at the DATEDIFF function.

E.g.

select datediff(mm,getdate(),getdate()+180)

T-Sql Distribute data into groups based on existing numbers

Hi, i've been looking at moving one of our processed from excel (+vba) into t-sql to make life easier but am stuck.

We have lots of tasks that are assigned to work groups which we want to distribute evenly across the work groups. This is a simple task for ntile.. However when these tasks are no longer required they are removed which leaves the groups uneven. When new tasks are added we want to still try to keep these groups balanced.

EG Existing groups :

GroupName - Task Count
Group1 - 1000
Group2 - 999
Group3 - 998

If we were to add 6 new tasks they would have more assigned to Group 2 & 3 as they have less than group 1.

Task 1 - Group3
Task 2 - Group3
Task 3  -Group2
Task 4 - Group1
Task 5 - Group2
Task 6 - Group3

Sample tables

SQL

Create table GroupTable
(GroupID int, Name varchar(200) )
Insert into GroupTable values (1,'Group1')
Insert into GroupTable values (2,'Group2')
Insert into GroupTable values (3,'Group3')


Create table Jobs(jobid int identity(1,1), name varchar(100),Groupid int)
--Existing tasks
Insert into Jobs(name,Groupid) values ('Task1',1)
Insert into Jobs(name,Groupid) values ('Task2',1)
Insert into Jobs(name,Groupid) values ('Task3',1)
Insert into Jobs(name,Groupid) values ('Task4',1)
Insert into Jobs(name,Groupid) values ('Task5',2)
Insert into Jobs(name,Groupid) values ('Task6',2)
Insert into Jobs(name,Groupid) values ('Task6',2)
Insert into Jobs(name,Groupid) values ('Task7',3)

-- New tasks
Insert into Jobs(name) values ('TaskA')
Insert into Jobs(name) values ('TaskB')
Insert into Jobs(name) values ('TaskC')
Insert into Jobs(name) values ('TaskD')
Insert into Jobs(name) values ('TaskE')
Insert into Jobs(name) values ('TaskF')

This gives us 6 unassigned tasks and a uneven group assignment

SQL

GROUPNAME   TASK_COUNT
<none>      6
Group1      4
Group2      3
Group3      2

This means the new tasks will be assigned like this

TaskA - Group3
TaskB - Group3
TaskC - Group2
TaskD - Group1
TaskE - Group2
TaskF - Group3

Can anyone help?
Thanks
Dan

Problem with Decimal Places and Rounding off

Good Day All

i have a Following Query

1) Query 1

SQL

 DECLARE @FINALVAUE VARCHAR(MAX) =   (Convert(decimal,@CAUSATIVE_FACTORS_ID) - 1) +   Convert(decimal,@LU_PERCENTAGE_FAILURE_IN_SAMPLE_ID) + Convert(decimal,@LU_REPORTING_HISTORY_ID)  
PRINT @FINALVAUE -- the answer is 3

The Calculation is like this

2) Query 2

SQL

 DECLARE @FINAL VARCHAR(MAX) 
SET  @FINAL=  (4-1) + 0.08 + 0.2
SELECT @FINAL -- the asnwer is 3.28

The first Query i am retrieving values from the Variables which are varchar and converting to decimal and doing the calculations. and the second Query i am just taking the value as is. i used this to debug in trying to solve this problem. My problem here in the first Query in the @FINALVAUE variable the answer is "3" and in the second Query the answer is "3.28"
, i want the first Query to display the same value which is "3.28"

Thanks

Select and Update

I'm trying to consolidate 3 operations into 1
Not sure if it's possible, but it's seems like it is.

I want to select some data, and take the data from 1 table and update it to another table.

Her's what I have. It's kind of a soup at the moment, experienenting with different ideas.
In my Create Table, I can't figure out how to use those value in the update in place of the parameters.
Perhaps I should just use the line in Update, the select for CardLabel.

DECLARE @CardID INT;
SET @CardID = 645;
CREATE TABLE #CCInfo
(
   Label VarChar(40) 
 , CardBrand VarChar(80) 
 , CardExpMonth VarChar(80)
 , CardExpYear VarChar(80)
 , CardHolder_FirstName VarChar(80)
 , CardHolder_LastName VarChar(80)
 , CardNum VarChar(80)
 , CardPhoneNum VarChar(20)
)
 INSERT INTO #CCInfo
 (
   Label
 , CardBrand
 , CardExpMonth
 , CardExpYear
 , CardHolder_FirstName
 , CardHolder_LastName
 , CardNum
 , CardPhoneNum
 )
 SELECT 
  Label 
, CardBrand 
, CardExpMonth 
, CardExpYear 
, CardHolder_FirstName 
, CardHolder_LastName 
, CardNum 
, CardPhoneNum 
 FROM CardInfoPerm  
 WHERE CardID=@CardID
 UPDATE
  OrderInfo
  SET
    CardID=@CardID
  , Cardlabel= (SELECT Label FROM CardInfoPerm WHERE CardID=@CardID)
  , CardBrand=Card_
  , CardExpMonth=@CardExpMonth
  , CardExpYear=@CardExpYear
  , CardHolder_FirstName=@CardHolder_FirstName
  , CardHolder_LastName=@CardHolder_LastName
  , CardNum=@CardNum
  , CardPhoneNum=@CardPhoneNum
  , PaymentInfo=@CardID
  , ApprovalCode=''
  , AuthorizationID=''
  , CheckID=''
  , CheckLabel=''
  , CheckType=''
  , CheckName=''
  , BankName=''
  , CheckRoutingNum=''
  , CheckAccountNum=''
  WHERE OrderNum='CA-2054'

Here I get must declare the scalar @CCInfo in the UPDATE Section
I understand what it means, I just don't know how to go about getting the scalar to be recognized in Update.
The first part works, just having trouble with the update.

DECLARE @CardID INT, @OrderNumber VarChar(40);
SET @CardID = 645;
SET @OrderNumber = 'CA-2054';

DECLARE @CCInfo TABLE
(
   Label VarChar(40) 
 , CardBrand VarChar(80) 
 , CardExpMonth VarChar(80)
 , CardExpYear VarChar(80)
 , CardHolder_FirstName VarChar(80)
 , CardHolder_LastName VarChar(80)
 , CardNum VarChar(80)
 , CardPhoneNum VarChar(20)
);

 INSERT @CCInfo
 (
   Label
 , CardBrand
 , CardExpMonth
 , CardExpYear
 , CardHolder_FirstName
 , CardHolder_LastName
 , CardNum
 , CardPhoneNum
 )
 SELECT 
  Label 
, CardBrand 
, CardExpMonth 
, CardExpYear 
, CardHolder_FirstName 
, CardHolder_LastName 
, CardNum 
, CardPhoneNum 
 FROM CardInfoPerm  
 WHERE CardID=@CardID
 
 UPDATE
  OrderInfo
  SET
    CardID=@CardID
  , Cardlabel=@CCInfo.Label
  , CardBrand=@CCInfo.CardBrand
  , CardExpMonth=@CCInfo.CardExpMonth
  , CardExpYear=@CCInfo.CardExpYear
  , CardHolder_FirstName=@CCInfo.CardHolder_FirstName
  , CardHolder_LastName=@CCInfo.CardHolder_LastName
  , CardNum=@CCInfo.CardNum
  , CardPhoneNum=@CCInfo.CardPhoneNum
  , PaymentInfo=@CardID

Separate the statements with semicolons?

I went for the later in this function, but found out later that I could of just declared and set all the card data first
and then run the UPDATE using the variables.

So I ended up with this, I shortened it to keep it more brief

UPDATE " & _
OrderInfo " & _
SET
  CardID=@CardID
, Cardlabel=(SELECT Label FROM CardInfoPerm WHERE CardID=@CardID)
, CardBrand=(SELECT CardBrand FROM CardInfoPerm WHERE CardID=@CardID)
, CardExpMonth=(SELECT CardExpMonth FROM CardInfoPerm WHERE CardID=@CardID)
, CardExpYear=(SELECT CardExpYear FROM CardInfoPerm WHERE CardID=@CardID)
WHERE OrderNum=@OrderNum"

But later the next day I ended up writing something that does everything in one shot, far beyond I could imagine that I can do. So I modified the above to this below

DECLARE " & _
@CardLabel VarChar(80)
, @CardBrand VarChar(80)
, @CardExpMonth VarChar(80)
, @CardExpYear VarChar(80)
, @New_OrderNumber VarChar(80);

SET @CardLabel = (SELECT Label FROM CardInfoPerm WHERE CardID=@CardID);
SET @CardBrand = (SELECT CardBrand FROM CardInfoPerm WHERE CardID=@CardID);
SET @CardExpMonth = (SELECT CardExpMonth FROM CardInfoPerm WHERE CardID=@CardID);
SET @CardExpYear = (SELECT CardExpYear FROM CardInfoPerm WHERE CardID=@CardID);

IF EXISTS(SELECT * FROM OrderInfo WHERE OrderNum=@OrderNum)
 BEGIN
  UPDATE
 END
ELSE
 BEGIN
  INSERT
 END

Then, I was able to do more,
delete previous cart items,
generate a new order number,
copy the cart contents over
return the new order number
all in one shot now, use to take me like 8 functions to do it all. I'm amazed at how fast it runs now.

I would post it, but it's too large

I'm stoked on how it came out, and learned a lot on my own. I think I got the semi-colons right this time, I need to read up on that.

Weird problem with UNION query in Access 2010

Peter R. Fletcher8-Aug-14 3:46

Peter R. Fletcher

8-Aug-14 3:46

I have created a UNION query as the source for a report that is written to a Word Document using VBA. The UNION joins a Table (historical information from before the current database Application was written) and the output of a Query that extracts corresponding information from the live data. I have recently added a new text field to both 'sides'. The value of the text field for the Query (either "S" or "") is generated in an IIF() statement within it.

When I Open the UNION query via the Access interface, it works as intended - the new text field is set to the correct value for records derived from either source. When I open a ADO Recordset based on the UNION query in VBA, the records derived from the Table are correct, but the contents of the new field in the records derived from the Query is always a Null String (N.B. not Null). If I convert the Query which is the second source of the UNION into a Make Table Query, run it, and then UNION the two Tables, everything again works as it should. Does this make any sense to anyone?

Hello, I would like to try either SSMS 2012 or SSMS 2014. However I would like to keep my SQL Server 2008R2 instance.

First what is your suggestion on downloading? I hear there are changes for 2014 that make it very different.

If I download SQL Server Express will it install an instance or can I choose to just install SSMS. Is there a download just for SSMS.

Thank you,

Try moving the insert inside the if statement, so you will need the insert twice

I want to convert it into (16/04/2014). When i use convert function it gives error message
Msg 245, Level 16, State 1, Line 2
Conversion failed when converting the nvarchar value 'Apr 7 2014 4:42PM' to data type int. We have so many scattered format so we cannot run a single query for specific data. so kindly provide solution for this problem.
these formats i have been using this statement to convet data.

select CONVERT(varchar(10), CONVERT(date,FormReceivedDate, 101), 103) from Applicant where FormReceivedDate=1
