Transact SQL :: Getting Last Record In Aggregation

Jul 17, 2015

I have daily data that I wish to summarise into monthly. The field [Close] will return the last day of the month that has a value.The query below summarises the data as I want it but using the max of [Close] in the month instead rather than the Last value for the month. In Access I used to use Last function that worked perfectly. From googling, Last doesn't seem to exist in T-SQL but there must be a way to do it.

    D.YearMonth_Number,max(AT.[Close])
FROM
      tbl_Date
ASD
INNERJOINtbl_ASXStats
ASAT
OND.YearMonthDay_Number
=AT.YearMonthDay_Number

Transact SQL :: Get One Record By ID Which Has Max Date

May 4, 2015

I have records like this

id      address1          date
1      xyz                 01/01/2013
1       abd                01/01/2014
2       dfg                 01/03/2015

Now what I want is just 1 record by id which has max date,if there is 2 records for same id, if there is 1 record then it should come.

So here result should be

1       abd                01/01/2014
2       dfg                 01/03/2015

Transact SQL :: How To Find A Non Matched Record In 2 Tables

Jul 15, 2015

I have 2 tables .Lets Say tableA and tableB.Both Have Columns ClaimNumber,Amount. Now, to get the matched records for these 2 tables, i wrote the following query Select * from tableA A Inner Join tableB B on A.ClaimNumber = B.ClaimNumber and A.Amount = B.Amount This query works perfectly fine and gives me only matching records, however if i want to have records which match with ClaimNumber and not with Amount i wrote something like this

Select * from tableA A Inner Join tableB B on A.ClaimNumber = B.ClaimNumber and A.Amount <> B.Amount.

And this query produces wrong results, its giving me match and also non match records.

how to write a query for my non match condition?

Transact SQL :: Remove Duplicate Records But Keep At Least 1 Record

I have a table that "Geography" that  has the following columns: city, state, zip

There are tons of duplicate cities in this table.  I ran this query and it shows me the number of occurrences of each city.  I want to delete all the duplicates except for 1.  I don't want to do this manually as there are a lot of records.

What would the SQL look like to delete the duplicate records but keep at least one?

Transact SQL :: Select First And Last Record For Certain Date Range

Jun 16, 2015

I have a situation where an agent has number of activities for a certain date range. If an agent has multiple activities within certain date range, I would like BALANCE BEFORE from the first activity and BALANCE AFTER from the last activity. Here is my current SQL query that returns the following data:

DECLARE @BeginDate Datetime
DECLARE @EndDate Datetime
Set @BeginDate = '05-1-2015'
Set @EndDate = '05-31-2015'
SELECT
a.AgentName,
R.BALANCEBEFORE,

[Code] ....

AGENTNAME          BALANCE BEFORE  BALANCE AFTER          DATE
DOUGLAS              9738.75                9782.75                     2015-05-11
DOUGLAS              9782.75                9804.75                     2015-05-12
DOUGLAS              9804.75                9837.75                     2015-05-13

In the sample data above, ideally I would like my query to return data as follow:

AGENTNAME          BALANCE BEFORE                  BALANCE AFTER
DOUGLAS              9738.75 (from first activity)    9837.75 (from last activity)

Not sure how I can write sql query to accomplish this.

As per the condition, it should ignore the record because DEF is already available . But my query is trying to insert supplier DEF and following that, I am getting primary constraint error.

Transact SQL :: How To Do Procedural Updates Based On Record String

Aug 16, 2015

How to do some procedural updates based on a record string. What I wish to do.

If the value (of type string) in my column contains the ‘/’ character I wish to ‘do something’
If the value (of my string) in my column contains the ‘-‘ character I wish to ‘do something else’.

Assume my column contains both ‘/’ and ‘-‘ in the same table.column, but not within the same record.

The data in question is in

tbl_Quotes.tLastDateValue
 
 I’ve found I can use something like this to search my string.
 
SELECT
Count(CHARINDEX('/',tbl_Quotes.tLastDateValue))
FROM tbl_Quotes
WHERE
CHARINDEX('/',tbl_Quotes.tLastDateValue)>0
 
And similar for ‘-‘ records.
 
I’m thinking something like this could be used as the test.
 
How do I put this into play, I’m thinking of an IF or CASE but not sure how to best test and which program flow to use in SQL.

Transact SQL :: Retrieve Latest Record Of Serial Number With Multiple Entries

Sep 30, 2015

I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.

I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,

Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.

Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.

S.Id

I4 To I8 In Aggregation

May 30, 2007

I'm using an Aggregation task to summarize an input file by item and week before inserting it into a SQL table.



Two of the fields I'm summing, because their totals per record can occasionally exceed 32k, are defined as int (I4) instead of smallint (I2). However, the summarized total never exceeds the value an int can hold.



I ran into a problem on the insert, however, with SSIS telling me it couldn't insert an I8 value into an I4 table field. I discovered the metadata for the summed totals had automatically been set to bigint (I8), and the mapping was failing.



I didn't see a way to change that metadata within the Aggregation task itself, so I added a Data Conversion task to convert the totals to four-byte signed integers and enable the mapping. Was that the proper workaround?
