Hi, I am searching for the most easy SQL solution:
Lets say i have 500000 rows of cars in one table with 30000 different car ID's.
This table contains no keys, no date values, but I need the last row of these 30000 different cars. How do I get them without adapting table structure and without using cursors ?
Yet another simple query that is eluding me. I need to find records in a table that have the same first name and last name. Because the table has a primaty key, these people were entered twice or they share the same first and last name.
How could you query this:
ID fname lname 10001 Bill Jones 10002 Joe Smith 10003 Sue Jenkins 10004 John Sanders 10005 Joe Smith 10006 Harrold Simpson 10007 Sue Jenkins 10008 Sam Worden
and get a result set of this:
ID fname lname 10002 Joe Smith 10005 Joe Smith 10003 Sue Jenkins 10007 Sue Jenkins
What is the best way to compare two entries in a single table wherethe two fields are "almost" the same?For example, I would like to write a query that would compare thefirst two words in a "company" field. If they are the same, I wouldlike to output them.For example, "20th Century" and "20th Century Fox" in the companyfield would be the same.How do I do this? Do I need to use a cursor? Is it as simple as using"Like?"
If I wanted to search for Jobs as a particular status (e.g. 0130) and wanted to keep the jobs at this status until it has reached 0500, 0125, or 0900 in it's subsequent status log entry, how can I write the SQL for it to achieve it?
I have the following SQL which searches for the Jobs at 0130, but don't know how to develop it further to search on the requirement above.
------ SQL ------- SELECT job.job_number, (SELECT MAX(jsl.job_log_number) FROM job_status_log jsl WHERE job.job_number = jsl.job_number AND jsl.status_code = '0130') as Last_Early_Warning_Status_Entry
[code].....
In the job_status_log table above, there is a job_log_number field which increments by 1 when there is a new status log entry.
I have a table which stores phone numbers of a customer in a table.
Say this table is as below
CustomerName - PhoneNumber Customer 1 - Phone number 1 Customer 2 - Phone number 2 Customer 2 - Phone number 3 Customer 3 - Phone number 4
What would be the best approach to prevent adding another entry against Customer 2. I should be able to add new customers and add multiple phone number against all other Customers. The restriction should be only against Customer 2.
I am trying to pull the last three entries from a table in my database but I am having trouble writing the correct query. The database has multiple entries for each item in my database but I want to pull just the last three for each item. I have tried the TOP function with the items ordered in descending order but that only works when I define each item seperatley. I need to know how to pull the last three entries for every item I have in the table.
Without technical information and DB design, I wish to know the maximum entries in MS SQL in million. I guest for access are a limit of 2 million and a 2GB DB. How much for MS SQL in max. entries and how much in GB?
I'm extracting data from a log (log_history) of patients where nurses perform various actions on a call, such as assessing and reassessing, despatching etc. This is the script:
Select L.URN, LH.THE_TIMESTAMP, LH.ACTION_TYPE, LH.ACTION_BY, LH.ACTION_REQD, LH.NOTE, em.position_type_ref From LOG L Join Log_history LH on (L.URN = LH.LOG_URN) left outer join employee em on (em.code = LH.action_by) Where (L.Taken_at >= :DateFrom and L.Taken_at <= :DateTo) and (LH.ACTION_TYPE = 'D') and (em.position_type_ref ='NU')
Order By L.URN ASC, LH.THE_TIMESTAMP DESC
The result I get shows duplicate 'timestamp' entries and I only want to return unique timestamp entries. Does anyone have any ideas. I'm self taught and have hit a wall
I need help desperately. The following is an example of the data that I have.
I have two tables one name Customers and the other named Orders. The tables have the following attributes
CUSTOMER CustomerNum, CustomerName, OrderNum
ORDER OrderNum, OrderDesc, CustomerNum
Bare in mind that the CustomerNum can have multiple customers attached to it, example a whole family (I know bad database design but it's too late to change) Let's use the following info for the tables respectively
The query i'm using is select Customer.CustomerNum, Customer.CustomerName, Orders.OrderDesc from CUSTOMER, ORDERS where CUSTOMER.CustomerNum = ORDER.CustomerNum
I have an application that allows the user to enter data into a table. There are multiple users so I put in some code that, I thought, would keep 2 users from creating a new record at the same time. The IDs for the records are identical and this is causing a problem.
The IDs are in the format of ####-mmyy. at the start of each month the #### part goes back to 1.
We tried a test today where we had 2 users click on the New button at exactly the same time. The IDs that were created were identical. Is there anyway on the database that I can prevent this from happening?
Here is how I create the new record id:
I get the MAX(ID) from the table I add 1 to the ID and then insert a new record with the new ID into the table.

Hello,does anyone know what could be wrong? There's a lot of similar entriesin the SQL Server current log:2004-01-21 17:54:00.01 spid57 Starting up database 'DB_NAME'2004-01-21 17:54:06.45 spid57 Starting up database 'DB_NAME'2004-01-21 17:54:59.13 spid56 Starting up database 'DB_NAME'There are hundreds of similar entries that repeat every few seconds. Thedatabase works quite slowly and the users get 'Connection timeout'message very often.Thanks for any advice....:: fabio
Hi All In my application i have to get the data from .csv file. My requirement is that file may consists of duplicate entries I ant to remove the dup entries and i want to place in the table. Waiting for valuable replies Thank u Baba
I have an issue where certain parts of data are repeated several times after i create my query. Without providing my SQL code for now could anyone suggest possibly the main reason(s) for data being duplicated?
Hi,I have a form that should show 2 pictures based on table entries.I want those 2 pictures to be randomly selected based on a database table. So, my table has all the entries, and I want to pull out a random entry that has been approved to display it.Can someone help me with the sql query?I can do SELECT VoteId FROM tblVotes WHERE Approved=True..But how do I make selection a random one that changes every time the user gets another entry?
Hello, I have a reference table. This table has an effective date and end date, and I need to get a single set of values at a point in time. Suppose the following hotel rating values are the values that I want to pull out of the table: 1 Star2 Star 3 Star 4 Star 5 Star This value has other information associated with it (benchmarks and such) and so it's possible that one of the 2 star entries gets end-dated, and then a new 2 Star entry gets created with an effective date and no end date. How can I query so that I only get one 2 Star entry at any point, and get the point in time where the date is between the effective and end date, but only pull back a single set of entries, one distinct rating value. So, suppose the first entry is end-dated 7/1, if I look at old data, I want to see the old benchmarks and so I want the previous entry end-dated 7/1; otherwise, I want to see the new end-date, with the new 2 star entry with no end date. How do I do that? Make sense?
I am a newb at ms sql and was hoping someone could help me eliminate duplicate PRODUCT.PRODUCT from this statement. I have tried using DISTINCT with the same results.The ProductImage table is causing this because the duplicates are from the PRODUCT.PRODUCT that have more than 1 image.
If anyone could rewrite this statement so I can learn from this, it would be most appreciated!

I have just started learning PHP and MS SQL. I was having a problem viewing the database (column entries) in the MS SQL server managemnet studio. I can see the column names but I cannot see the entries that I save in it. Ne help pls !!! Any yes the data is saved because when I use the "select" command I can print the data.
For example some data has entered into a table in a random manner i.e the pk filed value is not in a serial fashion.Is there any table or index that holds the entries of rows into a particular table as entered .
i.e 'some_table' has data like this
3,entry3 2,entry2 4,entry4 1,entry1
I want some DB table or Index that holds data like this about above 'some_table'
row_id .... .... .... 1 2 3 4
here 1 refers to entry of the first column in 'some_table' i.e 3,entry3 and so on...
Hey, I have some field values entries in my database.. that are spaces like ' '. i wanna eliminate them. When i use IS NOT NULL in query it only eliminates the rows with NULL values so how could i modify the query to eliminate the rows with spaces in the field value..
I have a DB of transaction log grown to 19GB. I have some questions. 1. Is there any way that we can minimize the entries to transaction log. 2. If i use Transactions in my stored procedure will it be usefull to automatically remove the transaction entries in transaction log once after the commit transaction is given. 3. Is there a way to reduce my current transaction log and not to grown in such a manner futher.
SELECT [TimeSheetConsolidatedId] ,[EmployeeId] ,[ActivityId] ,[StartedAt] ,[HoursWorked] FROM [SR].[dbo].[TimeSheetConsolidated_All] WHERE [StartedAt] > '2012-08-06 00:00:01.000' AND [StartedAt] < '2012-08-010 23:59:59.000' AND [ActivityId] = 10 ORDER BY [EMPLOYEEID]
This displays days that all employees have worked with a certain activity ID. Max 4 days Min 0 days. What I would be looking to do is remove any Employees from the table if they had worked all 4 days leaving only the Employees that have had a day or more off.
I might have approached this the wrong way but it is the only way I can think of getting the results I want.
I'm trying to run this as a Single Query in SQL Server Manager 2008.
Attachment shoes to Employees one with 4 entries who would be removed from the view the other with 3 who would remain the focus of the report.
I have a table where each unique entry can have up to 12 'modes', each mode with a start and stop date. A mode is a certain type of characteristic attributed to an entry.
There are 60 different modes and a given mode number can appear in any of the 12 mode fields. I created a very simplistic example table below.
Criteria: I need to find all entries that have any of the modes = 1
AND for any of the other mode fields = 2 or 3, all modes = 2 or 3 must have a mode_enddate that is NOT NULL.
example: select * from #temp_work where (mode1 = 1 or mode2 =1 or mode3 = 1 ...)
And if any of the other mode1-12 fields = 2 or 3 then all mode 2 or 3 mode_enddate must be NOT NULL. I have tried a few different ways to try and get this data, but none of them have been very good.
Create temporary table create table #temp_work ( id int NULL, mode1 varchar(20) NULL, mode_startdate_1 date NULL, mode_enddate_1 date NULL,
[Code ....
From this limited example, the only valid entry should be ID 1 as the mode = 3 has a NOT NULL mode_enddate.
ID's 2 and 3 both have mode_enddate_X that are NULL, so should not be included.
SELECT post.C_ID, post.Comment, post.Title, post.Date, authors.U_Name FROM authors INNER JOIN post ON authors.A_ID = post.A_ID ORDER BY C_ID DESC
That's the query I'm using, and I was hoping there is a way to use the WHERE clause to have only the 5 highest #'s from my primary key, which is A_ID IDENTITY(1,1).
What would be the best way for me to do this? I also have date as a datetime, but then I could be getting more or less than 5 results in my query.
I have a table in our system that hold temporary data for doing calculations. It will process several million records in it. each time they forecast our products.....
Is there any way to have the SQL server NOT add these transactions to the transaction log, since I'm going to wipe the data anyway? I'd like to be able to pick and choose the tables that are 'backed up' into the transaction log...
