SQL 2012 :: Datetime To Date Datatype Increasing Index Size?
Mar 6, 2014
I have a database which is centered around two date tables (approx. 5.5 million records each). We are finally making the big leap from SQL Server 2005 to 2012. The data is currently stored as datetime, and we are hoping to take advantage of the new date datatype, since the time component is not needed.
The first table has 13 different date columns. In testing on the 2012 server I have changed 3 columns so far, and have seen that changing the datatype to date is actually increasing the Index size and not affecting the data size. Only 3 of the columns are associated with indexes, and modifying a non-indexed column still increased the index size. I am running the Disk Usage by Table report to view the sizes.
I have below SQL, which should be order by posteddate ASC
SELECT AnnouncementID,[Subject],[Description], CONVERT(nvarchar(10),PostedDate,101) AS PostedDate, CONVERT(nvarchar(10),ExpiredDate,101) AS ExpiredDate, CountryID,CreatedBy, CreatedDate, ModifiedBy, ModifiedDate FROM Announcements a WHERE isActive = 1 AND CountryID = 2 AND (GETDATE()>= PostedDate) AND (GETDATE()<= ExpiredDate) ORDER BY PostedDate ASC
But result is displaying as below, PostedDate datatype is datetime
For some reason, I recall having read that SQL Server 2005 would supporta datatype that represented date, but not time. (This would be usefulfor storing things like birthday, where you usually don't care about thetime of day). But I've got SQL Server 2005 installed, and there's nosuch datatype to be found.Is this something that might be released in a Service Pack, or is itjust not going to happen?
I have a requirement to be able to select and group records by the date portion of a datetime field. ie ignore the time when grouping so that all records lodged on a particular day are seen together.
I have been able to do this by
- converting the datetime data to the number of days since a given date - inserting this into a temporary table - retrieving the the data from the temporary table - convert the data back to a date using DATEPART to display dd/mm/yy
This then gives me the data grouped as required but seems to be a very difficult solution - Is there an easier way??
I have a table where the Primary Key is of datatype DATE. This column is also a clustered index. Since not every day is in this column i am looking for a way to address a date one ( or two, or three) Dates before a given date. Something like:
select * from myTable where [date] = one record previous to record where date = '22-05-2000'
We are migrating our database from DB2 8 to SQL Server 2005. We have date and time saperate columns in DB2. For example, Date_of_birth, Store_sun_open_time, Store_sun_close_time etc. For date we are using datetime. For time what datatype should we use in SQL Server?
Need some quick help here.. The data I got from the text file use the "04/11/2007" date format and the StockDate in MS-SQL use the datetime datatype.
My understanding is that the "04/11/2007" will default to the 04/11/2007 12:00 am" format in MS-SQL.
So, when I use the sql query, how do search only for the date part of the data in MS-SQL and match it to the data from text file? I tried this SQL Query below.
--snip-- SELECT RawID FROM tblPurchaseRaw WHERE VIN = '" & sVin.ToString.Trim & "' AND StockDate = '" & dStockDate.ToString.Trim & "' --snip--
That way, if I get a row then I know the data is there. If I don't get a row then I know the data is not there.
Bold: I get it now. It is all automatic as MS-SQL does it automatically...
Can I know somedetail about why the Sqlservr.exe app increasing in size drastically. Even I check all parameter of the server and I check the process running on server.
I feel server is not releasing the queues and It is occupying the memory. I any one suggest what could be the cause ?
I am having trouble increasing the size of the log device on a SQL 6.5 database. When I use SQL Enterprise Manager I get an error saying that the device has 0 MBs available. When I use the ALTER DB statement I get an error saying that there is not enough space on the disk, but I know this not to be the case. Has anyone any suggestions? Thanks in advance, Michael lawlor
I have a database with 1 .mdf data file and 1 .ldf t-log file. There are multiple inserts/deletes/transactions performed on the data daily, but the size of the two files remains constant (5,774,,336 and 153,480 respectively)??? I perform daily full backups and hourly T-log backups (during business hours of 9-6) and these backup files change size, but why aren't my physical DB files changing? I have them set to auto-grow at 10% unrestricted...
Is there a way to increase the size of the procedure cache. Or is it only a auto configuring option. I have 2gb of memory, and when I check the size of the procedure cache it is just 10mb. I would like to increase this to around 50mb. Not sure if there is an setting to do this. Had a look on BOL could not find anything.
Just wondering if you could help me on this one. I'm not sure if mytransaction logs are behaving oddly or what. I've successfuly managedto shrink my transaction logs from 7GB down to 1MB and now I find itstrange that the log file doesn't seem to increase its size. Thetimestamp of the logfile is updating as well. But the size of the fileis constant. I haven't configured my database to do auto-shrink so Imreally confused why it hasn't changed its size for more than a monthnow.Hope I'm not losing any data here.Kindly advise.
i have a very big database and number of people are working on it.. it's log file size is increaseing very day too much.. i am taking log back every 30mint...
i dont' know that wethare i need to truncate the log file after taking the log file backup or not.. i am taking differentail backup every day and full backup every week...
Please tell me do i need to trucate the log file to reduce the file size or i hv to leave as it....
I am using SQL Server 2000 with replication object for two location. Log size on publisher go upto 25 times of data file size, I mean 80 MB Data files has maintains 2 GB log file and it is same for all five co's working on same windows 2000 advanced server board.
Since last week server randamly get disconnected from user applications and at that time few tables are not openable at server.
Can any one give a reason ? Why this type misbehaviou done by SQL Server 2000?
data source=RemoteHostName;initial catalog=myDb;password=sa;user id=sa; Max pool size = 200;
And now strange thing is happening ,, I am receiving error :
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached
The SqlServer Activity Manager is telling that only 100 connections are pooled, and I guess that the Max pool size is 100, It is not being changed by my Connection string. As I am trying to change the default 100 pool size value to 200.
Huh , So stucked up , how to increase the Max pool size.. Is there any way .
I have a field in a table that stores date of birth. The field's datatype is char(6) and looks like this: 091703 (mmddyy). I want to convert this value to a datetime datatype.
What is the syntax to convert char(6) to datetime?
What would be the most economy solution for this WHERE, I see the code where we have covnert to 101 type on both sides of equation, which I tnink is not right.
So I'm thinking to put it on the left like this, just curiouse is this the best solution, I also heard that TSQL interpret between even better , here I'm really care abour performance.
declare @DATE DATE = '01/14/2014' --A: SELECT * FROM TT WHERE CAST( TT.DATETIME AS DATE) = @DATE
--B: SELECT * FROM TT WHERE TT.DATETIME >= @DATE and TT.DATETIME < DATEADD(D,1,@DATE)
I need to find all the index and the creation date. I did cross apply of sys.objects & Sys.indexes on name column. I am getting some but the team is saying they created so many. Any other option to find Indexes and their creation date?
I'm using foxpro and I'm completely new to SQL. I'm trying to create a database into which I need to enter a time field. I've read around on the net that the only way to do this is using a datetime datatype but I can't find anywhere that explains the format I use to INSERT INTO my tables.
Anyone help?
*EDIT* I actually just want to enter the time and not the date and the time, I have read it is possible to do this using a convert but I'm happy enough to have the date and the time as I don't want to overcomplicate anything at this stage.

Is there any method to find out the size of an image datatype currently in the database. For example I have 2 tables that contain the same image, but the archive table is not displaying the same as the main. I am thinking the image file was corrupted somehow but don't know how to check this out. Any ideas?
Are we allowed to do a LIKE datetime in SQL queries? The records data looks like so: 9/21/2000 10:30:40 AM But I want to see model requests by an entire day ala: Select * From ModelRequests Where RequestDateTime Like '9/21/2000%' But I do know get any records returned. What is the special way of dealing with the datetime datatype for these purposes?
Hello! Here's the puzzle I'm trying to solve. I have 2 columns (CreatedDate and StatusDate) in the table both of datetime datatype. When I run query select * from sale where Statusadate = "11/30/2001" it returns rows back.
When I do the same but for CreatedDate column select * from sale where CreatedDate="11/30/2001" it returns zero rows back even if there are CreatedDates = "11/30/2001".
I don't understand why it works for one column and doesn't work for another one.
The example of CreatedDate value is "2001-11-30 10:10:33.000"

hi everybody, i'm trying to calculate the 'SUM' of time spent in hrs. n min. How can i do this using SQL Server? What i mean is, i've a column 'TIME_SPENT' that has 'datetime' datatype. This column saves time spent for an activity in format 'hh:mm'. Suppose a user spends 45min for activity 'A' and say 1hr 25 min for activity 'B' then i want to calculate the 'SUM' of 'TIME_SPENT' for the user which should appear as 'Total time spent =2:10'
