I want to fetch below 3 records from the above scenario i.e. latest record of each amount (Latest is determined using "descr" column i.e. 4 is greater then 3 -
select DayRank = ROW_NUMBER() OVER(ORDER BY a.datedel DESC), a.order,a.line,a.datedel,a.recpt,b.status, b.item,b.t_sup from historytbl a inner join order b on a.order = b.order and a.line = b.line and a.status =4 group by a.order,line,a.datedel,a.recpt,b.status,b.item,b.sup
I have a table T (a1, ..., an, time, id). I need to select those rows that have different id (GROUP BY id), and from each "id group" the row that has the latest field 'time'. Something like SELECT a1, ..., an, time, id ORDER BY time DESC GROUP BY id. This is the wrong syntax and I don't know how to handle this.
hopefully someone can suggest the best way of implementing the problem i am trying to resolve. We have a table which contains rows relating to tests run on our product. This table is populated from an SSIS job which parses CSV files.
There are multiple rows per serial number relating to multiple tests. The only tests i am interested in are the ones with an ID of T120. Here is the query i have so far which should make it a little easier to explain:
SELECT [SerialNumber] ,Param1 ,[TimeStamp] FROM [Build Efficiency System].[dbo].[SSIS_SCANNERDATA_TBL] WHERE Test = 'T120' GROUP BY SerialNumber, Param1, [TimeStamp] ORDER BY SerialNumber
What i have above is fine to a point. The problem i am encountering is that in test T120 it specifies a part which can be be one of about 6 in field Param1. If during testing there is a problem with the part then it is replaced and the test run a second time up until the whole product passes the test. The query above returns all instances of replacements so i may have the out put as follows:
When I give job Id in filter of this query this will give job status of "Success" but actually my job is currently in executing stage. I want to get all jobs that are currently in executing status.
Use msdb go select distinct j.Name as "Job Name", --j.job_id, case j.enabled when 1 then 'Enable' when 0 then 'Disable'
I have to find the latest file in a folder and export data to a table in sql server. The code should be something that has to be incorporated into a t-sql stored procedure.
The file name would for example abc_defYYYYMMDD.xls. would i be able to find the latest file in the folder using the the datestamp (YYYYMMDD) in the filename.
Please note i would have files in other format and names with datestamp attached to it, so the code has to pick specific file for which the file name starts with 'abc_def'
Not sure how to do this. I think I need to use a Group By query. I have a "Products" table with the following fields:
Program# Number UPC Item Item# Size Dept
Everything is specific to the Program#. In other words, for every instance of a Program# there can be more than one Product, which is specified by the "Number" field. So: SELECT * FROM Product WHERE [Program#] = '12345' should return this:
In which case I have to fix them (the "Number" field) with an update query sp they are numbered sequentially. Luckily, this doesn't happen very often.
Can someone help me with a query that will return only those records with duplicate values in the "Number" field? I am not sure how to construct this query which I will use as a stored procedure.
I have a question regarding SQL Server Performance and would be grateful for a tip. Let's say I have a DB with 50.000 records. These records belong to 1.000 different datasets, so there is 1 actual and 49 historical data records. For example a company with 1000 employees has a database where each year a new record is created for each employee so after 50 years they have 50.000 records (50 years x 1000 employees). 1 record is actual, and 49 are historical. What is the best way to store this? Main target is performance for the enduser, so when an employee clicks "See all my records" it should be fast. But on the other hand the application mainly works only with the current year. Additionally it should also be fast for the boss of business unit who wants to see the latest records of his e.g. 100 employees. I have some ideas and would like to get your opinion:
1. Retrieve by latest date Just store the records. To get the current year just select the record with the latest year. Disadvantage might be with larger databases: If the company switches to store the requests per month, each user would have 600 records (12 months x 50 years). Each time the latest record should be retrieved, 600 recards have to be compared regarding the latest date (or sorted by date descending using Top1, but this might be a problem for the boss then? Or could this be combined for a group if the boss wants to see all the latest records of his employees?).
2. Add a 'IsCurrent'-Flag Each time a new record is stored it should be compared to the latest record. If it is newer, the 'IsCurrent'-Flag should be removed and then checked on the new record. This should be fast processed (because on saving a new record it only needs to be checked against the currently 'IsCurrent'-flagged record), and for retrieving the current record no further comparison is necessary. But how could I do this? I need to update the "AddRecord"-SP with this comparison, but I don't know how to do this.
Currently number 2 is my favorite, I just don't know how to do it ;-) What is your opinion about it, and could you include an example?
The following SQL query :-SELECT CardHolder.RecordID, History.GenTime, History.Link1FROM History FULL OUTER JOINCard ON History.Param3 =LTRIM(RTRIM(Card.CardNumber)) FULL OUTER JOINCardHolder ON Card.CardHolderID =CardHolder.RecordIDWHERE (Card.Deleted = 0) AND (History.GenTime IS NOT NULL)ORDER BY CardHolder.RecordID, History.GenTime DESCreturns :-RecordID GenTime Link12 04/06/2004 15:30:00 1232 01/06/2004 16:00:00 1232 01/06/2004 08:00:00 1101155 02/06/2004 11:30:00 1231155 02/06/2004 08:00:00 1103925 03/06/2004 09:00:00 1233925 03/06/2004 08:00:00 1104511 06/06/2004 11:30:00 1234511 06/06/2004 10:30:00 110Is there a way of modifying this query to just return the lastestgenTime for each RecordID ??? ie return just rows 1,4,6 & 8.I assume it is something to do with MAX, but I can't seem to get myhead around it.Any help, or pointers would be appreciated.Oh, running query on Microsoft SQL Server 2000.RegardsDave

I am working to move an application from MySQL to SQL Server. The person who developed the MySQL application has little database experience, and took some shortcuts that the lax nature of MySQL allows. One query with which I am struggling looks something like this:
SELECT StartTime + Offset, min(Sensor), max(Sensor) FROM SensorData WHERE SensorID = @SensorID AND StartTime + Offset > @BeginTime AND StartTime + Offset < @EndTime GROUP BY (StartTime + Offset) / 100 ORDER BY StartTime + Offset
What we are trying to accomplish is to return minimum and maximum sensor values over a number of periods between the BeginTime and EndTime. When I run this query in MySQL on a sample dataset, it returns a small number of rows, with each one being the min/max values for a portion of the overall period.
Under MS SQL Server 2008, SP3, I get the two following error messages: Column 'SensorData.StartTime' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. Column 'SensorData.Offset' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
'Banquets - All Day' as revName, SUM(t.c_items_total) AS Banquet_Total, SUM(t.cover_count) as Total_Covers, -- (t.c_items_total) / (t.cover_count) as AvgPer_Cover--
[Code] ....
The output needs to be grouped by the t.c_items_total...I just need the avg per cover (person) / items_total.
select b.isin, a.market, a.ccy, a.stock_mkt, max(a.year) ,max(a.month), max(a.day) from market_table a inner join isin_table b on a.id = b.id where a.isin_closing_date=0 and a.market in ('XFFA', 'XFFA') and b.isin_type= 'I' and b.isin = 'DEX' group by b.isin, a.market, a.ccy, a.stock_mkt
what's needed is to get the earliest record all times, no mater the currency :
Let's say I have a table of data as per the below..
I'm trying to extract only the green highlighted items..
The rules applied are: Only the latest data concerning all cases, and only 1 line (the latest) per case.
As you can see in the image, I don't want the 2nd,3rd, and 4th record extracted cause they are all superseded by more recent records (identified as they are further in the table).
I've considered using either Distinct or Having? but can't get that to work.. If I could use Distinct but then ensure it's the latest record in the table that would be perfect.
I want find all dependent objects related to a table. I am using -
SELECT DISTINCT so.name INTO #tmp FROM dbo.sysobjects so JOIN dbo.SysComments sc ON sc.id = so.id WHERE sc.text LIKE '%tablename%'But, I want all those SP/functions/views that use the output of this query and so on...
Eg. Table -> used in usp1 -> usp1 used in usp2 ...and so on
Script to find a value in all databases ? for example I want to find a value contain word “ SQL” in all databases so I will get the information in which database and which table it exists.
My script is only for finding a value in one database.
I have a query that finds all SPID's connected to a particular database:
select d.name, p.* from sys.databases d join sys.sysprocesses p on d.database_id = p.dbid where d.name = 'my_db'
But now we have a new rule that we should not use outdated compatibility views, and one of them is sys.sysprocesses. I checked sys.dm_exec_connections/session/requests but failed to replace my existing code. The first two don't have dbid, the last one, requests, has it, but it selects only currently executing statements.
I'm presented with an issue where by I need to reclaim a fair bit of unused space currently sat in the primary data file for my database. I don't want to run DBCC SHRINKDATABASE as we all know this could potentially have a some serious negative effects relating to index fragmentation.
So, how do I get the free space out of the data file? - I've decided to:
1. Add new new file group 2. Add a clustered index for all tables on the new file group 3. Shrink the primary file group as much as possible (hopefully giving me the free space back) 4. Drop the newly created clustered indexes for all tables
There are no clustered indexes currently for any of the tables!, so me temporarily creating/dropping one shouldn't be an issue. Are there any other ways I can get the free space back to the OS?
I have groups of records in a table, and I would like to set a necessary condition on each group. The condition is that EXACTLY ONE of the records in each group has a flag field set to True (bit = 1). I can naturally write triggers for update, insert and delete events that test for such a condition.
Something along the lines of this condition:
(select count(ClovekAutoID) from TableOfClovekNames tCN where JeHlavni = 1 group by ClovekAutoID having COUNT(JeHlavni ) > 1) = 1In fact,
I tried this just on whim, but naturally, the SS engine told me to go roll my hoop, that subqueries are not allowed in constraint expressions.
I'd like to get the column ID_NumofAttach to be populated by the total number of ID_Attachlevel column by the same ID_BegAttach or ID_EndAttach and populate where ID_Attachlevel is 0.
I have express edition [advance] of sqlserver 2008 r2 , is it possible to trace every event with out using profiler as u know it does not ship with it.
Basically i want to see how locks are taken and released in each isolation level when query is executed. I am using
Recently I needed to find all processes connected to a particular database, let's call it Test_db. I have a simple query to find all connections to my database:
select * from sys.databases d join sys.sysprocesses p on d.database_id = p.dbid where d.name = 'test_db'
But there was a process that was connected to another database like USE another_db_name; but was actually selecting from tables in test_db. Is it possible to catch such connections?
