Selecting Min And Max Of Multiple Records?
Sep 27, 2013
What I need is the start and end time of each task, but the issue is there is no unique task number to bind them together.. So for instance the task starts with 'Open-Submitted' and ends with 'Task Approved'. The issue is there can be multiple occurrences in the same file number. I need to be able to split these into multiple tasks with the associated start and stop times.
File IDDatetimesTask Event StatusTask Event NameTask IDEvent ID

Hey all,I am having some serious trouble getting the correct syntax for a select statement to work the way I need it, any help I could get on this would be greatly appreciated.I have a table called Units which stores computers and a table called Software which stores software. I have a bit field in Units called OEM, when this is set to true I don't want the select statement to pull this unit down when I am assigning software to other units.Here is my select statement: SELECT Software.SID, Software.SN, Software.Name, Users.First + ' ' + Users.Last AS 'Assigned User', Units.Make + '-' + Units.Model AS 'Assigned Unit' FROM dbo.Software LEFT JOIN dbo.Units ON Software.SN = Units.SN LEFT JOIN dbo.Users ON Units.UID = Users.UID WHERE (Units.OEM = 'FALSE') AND (Software.SN LIKE '%' + @SearchString + '%')Everything works as expected, unless of course the unit has no software assigned to it yet, it won't return it because its not tied to a Units.OEM field. Is there anyway to have it return ALL records that even arn't joined OR are joined but have OEM set to false?Thanks, let me know if I need to clear anything up.-Matthew

Hi All,I'm trying to solve this for a few days now and I just can't figure itout...I have three tables set up, I'll simplify them for this question:Table 1: HOTELSColumns: HOTEL_ID, HOTEL_NAMEExmple row: 123 || 'Hotel X'Table 2: SERVICESColumns: SERVICE_ID, SERVICE_NAMEExample rows:1 || 'Breakfast in bed'2 || 'King size bed'Table 3: LINK_HOTELS_SERVICESColumns: FK_HOTEL_ID, FK_SERVICE_ID, SERVICE_VALUEExample rows:123 || 1 || 1123 || 2 || 1In table 3 I link different services to different hotels. In the same tableI set the "value" for the service.The first example row of table 3 means something like: Hotel X offersBreakfast in bed. In this case 1 stands for TRUEThe second example row of table 3 means: Hotel X offers King size beds(again: 1 stands for TRUE).What I'm struggling with is selecting the hotel ID's which offer multipleservices. To stay in the example: how can I select all hotels whereSERVICE_ID = 1 AND SERVICE_ID = 1. I can't seem to figure out how to doit...I hope anyone can help... Thanks a lot in advance!!!Robert

I need to list all the records in Table2 which don't have matching field values in Table1.
This the the exact opposite of what I need:
SELECT DISTINCT
Field1,
Field2,
Field3,
Field4,
Field5
FROM
[Table1]
WHERE EXISTS(
SELECT DISTINCT
FieldA,
FieldB,
FieldC,
FieldD,
FieldE
FROM
[Table2]
)
The above seems to give me all records in Table1 in which the five fields match the five fields specified in Table2. What does not show up is the test record I put in Table2 which is not in Table1.
What I need, however, is the exact opposite.
I tried the above using NOT EXISTS but I get no records at all.
How do do this?

and Table2.Dimension in (Select Dimension from Table1)
In Table1 There might be 10 Groupid records all of which are different.

This might be a simple question. I have a LIKE statement that is working fine, however I am not sure if something else is possible.
I can pull all records on a query for a person's name with a parameter value of "MARTIN". It will also pull records for "LYNN MARTIN". However, what if I would like to have that search also pull "LYNN M MARTIN"? Currently "LYNN MARTIN" is not finding "LYNN M MARTIN".
When the end user wants to search on LYNN MARTIN and that is what they input, I want SQL to find all records that match LYNN MARTIN and also find records that HAVE LYNN % MARTIN.
I hope this make sense? I guess I need to build my select statement using a WHERE LIKE statement, but I am not sure of the syntax.

Hi, my sql is not too hot so i hope someone can help me. I need to select all the records from one table that do not exist in 2 other tables. I know it sounds simple enough but for some reason i can not get it working. It may have something to do with the fact that the field i am searching on are datetime fields. Here is a shortened version of my code.
SELECT DateOfStats
FROM table1
WHERE (DateOfStats NOT IN
(SELECT dateofstats
FROM table2)) and (DateOfStats NOT IN
(SELECT dateofstats
FROM table3))
Thanks for the help in advance.

Hi,
Here is a basic example of the issue I am having:
Table 1 columns - name, address, zipcode, favorite food
For table 2 I want to find how many zipcodes exists and also take 20% of the count
Table 2 columns - based off Table 1 contains zipcode, count(zipcode) as ct, count(zipcode) * .20 as perc_ct
For example:
zipcode ct perc_ct
83746 10 2
93847 20 4
I want to run a query that will pull any 2 records for 83746 and any 4 records for 93847 from Table 1.
Is this possible?

Good Morning,I have a view that contains rate information, contractIDs, and effectivedates.I need to select the rate info based on contractID and date.I can provide a date and contractID, and I need to select the rate info forthat contract where the effective date is <= dateprovided.I need the 1 record that is closest to that date.I am thinking something with max() perhaps. Any ideas? The <= effectivedate will return several rows, I just need the one closest to the date Iprovide.Thanks for any advice,CK

I want to run a query that returns say 100 records...but I only want to return first 10 for first page on a web page, then on page 2 the webpage will return rows 11 to 20 of the same SQL statement...page 3 returns rows 21 to 30 rows etc....(eg. like Google or bulletin boards, browsing auctions in ebay etc.).
I could probably get my application logic to handle this (ASP.net), for instance I could possibly get a datareader to skip the first 10, output the next 10 then stop for page 2 (records between 11 amnd 20) but is there way to do this in SQL Server at the database level using an SQL Statement?
I can use TOP 10 to get the first set of records for the first page eg.
SELECT TOP 10* FROM Suppliers
...but how do I get between 11 and 20, 21 and 30 and so on?
I've already mentioned I could handle this in my application logic, but then each time the same SQL Statement is fetching all 100 records, even though the web page will only display a certain range. I'm building an intranet website that can potentially run queries that return 100'000s records, even though initially only top 20 or so records are display, each page they subsequently go to will rerun that same query that returns all 100'000 records. So handling this as part of the query would be better for performancr I reckon.
Someone gave me the syntax..
SELECT *
FROM employees
LIMIT 10,10;
..but it didn't seem to work.
Thanks for any help!!
