SQL Server 2008 :: Temp DB Size Values From Different Tables

May 25, 2015

For finding size values of temp database:

select * from sys.master_files -
size column value here is 1024 for .mdf,size here for .ldf is 64
select * from tempdb.sys.database_files -
size column value here is 3576 for .mdf,size here for .ldf is 224

Why is there a difference and not the same. size columns in the above 2 tables for temp db's do they represent different values ?

SQL Server 2008 :: Service Broker And Temp Tables

Feb 12, 2015

Let's say that I have a stored proc that is assigned to a service broker queue and is constantly running while it waits for messages in said queue. When a message comes in on the queue, the stored proc creates a table variable based off of the contents of the message and performs various operations with the data. Since the stored proc is constantly running, do the contents of this table variable ever truly get emptied? Should I be deleting the contents of the table variable at the end of the operation to ensure that stale data doesn't persist?

SQL Server 2008 :: Temp Tables Persisting In TembDB

Apr 30, 2015

I've recently started a new position and our production box. Contains a procedure that uses 30 + temp tables. I'm currently not in a position to change this as it's production and I would have to be granted a window to re-design.

However the tempDb is showing some strange activity.

If a table is created #CarrierService (CarrierServiceID,DeliveryZoneID,CollectionZoneID) for example

Once the procedure is called It will appear in the tempDB with the session info appended as expected


However once the session has ended the above table will get dropped and a new one created

#2C78E45A, I now have 7000 of these different Tables in the TempDB

When I Interrogate this using

SELECT o.name, o.create_date,o.modify_date , c.Name,C.Column_Id
FROM tempdb.sys.Objects o
Inner join tempdb.Sys.Columns c
ON o.object_id =c.Object_ID
WHERE o.type ='U'

I get the Following results

name create_date modify_date object_id name
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282CarrierServiceId
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282CollectionZoneId
#2C78E45A26/04/2015 18:0930/04/2015 14:55746120282DeliveryZoneId

Notice How It's getting Modified today.

SQL Server 2008 :: How Temp Tables Associated To Deferred Recompilation

May 25, 2015

1) "Deferred compile" recompile event occurs because of deferred name resolution. In other words, an object referred to in the statement does not exist at compile time. Later, when the object does exist, it requires a recompile of the statement so that it can create an optimal execution plan. One example of when a deferred compile will occur is if a temporary table is used in a batch and does not exist when the first statements in the batch are compiled.

SQL Server 2008 :: Turning Complex Query Into Temp Tables

Mar 5, 2015

do you have a general rule of thumb for breaking a complex query into temp tables? For someone who is not a sql specialist, a query with more than a few table joins can be complex. So a query with 10+ table joins can be overwhelming for someone who is not a sql specialist.

One strategy is to break a problem into pieces so to speak by grouping together closely related tables into temp tables and then joining those temp tables together. This simplifies complex SQL and although not as performant as one big query it's much easier to understand. So do you have a general rule of thumb as far as a threshold for the number of joins you include in a query before you break the query into temp tables?

SQL Server 2008 :: Comparing Tables For Like Values?

Jul 17, 2015

I have a table of raw data with supplier names, and i need to join it to our supplier database and pull the supplier numbers.

The issue is that the raw data does not match our database entries for these suppliers; sometimes there are extra periods, commas, or abbreviations (i.e. FedEx, FederalExpress, FedEx, inc.) etc. I'm trying to create a query that will search for entries that are similar.

I tried setting a variable to be equal to the raw data field, and then using a LIKE '%@Variable%' to try and return anything that would contain it, but it didnt return any rows.

Database Size Info Without Cursors Or Temp Tables

Jan 22, 2004

I have seen a bunch of ways to get the size of all the tables within a database posted on this board. I decided to modify an older one I found here (http://www.sqlteam.com/item.asp?ItemID=282). I set it up so there is no cursors or temp tables. Pretty much just one select statement to return all the info you would need. It seems to be faster than anything I have seen so far. Take it for whats its worth. Thanks to the original creator.

SQL Server 2008 :: Comparing Integer Values Across Tables And Database Servers?

Mar 6, 2015

how best to approach a problem involving two tables across two different servers.

Table 1: Contains IP Address along with assessment findings. Lets say the fields are IPADDRESSSTR, FINDING

Table 2: Contains Subnet information stored in integer format. The fields are SITE_ID, LOW, and HIGH

What I'd like to do is load the IP range information into memory and then return the findings from table 1 where the IPADDRESSSTR is between the LOW and HIGH integer value.

1) Is there a way to load all of the ranges from table 2 into an array and then compare all the IP addresses (IPADDRESSSTR) from table 1?

2) How do I convert IPADDRESSSTR (a string) to an integer to perform the comparison.

A Curious Error Message, Local Temp Vs. Global Temp Tables?!?!?

Nov 17, 2004

Hi all,

Looking at BOL for temp tables help, I discover that a local temp table (I want to only have life within my stored proc) SHOULD be visible to all (child) stored procs called by the papa stored proc.

However, the following code works just peachy when I use a GLOBAL temp table (i.e., ##MyTempTbl) but fails when I use a local temp table (i.e., #MyTempTable). Through trial and error, and careful weeding efforts, I know that the error I get on the local version is coming from the xp_sendmail call. The error I get is: ODBC error 208 (42S02) Invalid object name '#MyTempTbl'.

Here is the code that works:SET NOCOUNT ON

CREATE TABLE ##MyTempTbl (SeqNo int identity, MyWords varchar(1000))
INSERT ##MyTempTbl values ('Put your long message here.')
INSERT ##MyTempTbl values ('Put your second long message here.')
INSERT ##MyTempTbl values ('put your really, really LONG message (yeah, every guy says his message is the longest...whatever!')
DECLARE @cmd varchar(256)
DECLARE @LargestEventSize int
DECLARE @Width int, @Msg varchar(128)
SELECT @LargestEventSize = Max(Len(MyWords))
FROM ##MyTempTbl

SET @cmd = 'SELECT Cast(MyWords AS varchar(' +
CONVERT(varchar(5), @LargestEventSize) +
')) FROM ##MyTempTbl order by SeqNo'
SET @Width = @LargestEventSize + 1
SET @Msg = 'Here is the junk you asked about' + CHAR(13) + '----------------------------'
EXECUTE Master.dbo.xp_sendmail
@query = @cmd,
@no_header= 'TRUE',
@width = @Width,
@dbuse = 'MyDB',
@subject='none of your darn business',
@message= @Msg

The only thing I change to make it fail is the table name, change it from ##MyTempTbl to #MyTempTbl, and it dashes the email hopes of the stored procedure upon the jagged rocks of electronic despair.

Any insight anyone? Or is BOL just full of...well..."stuff"?

SQL Server 2008 :: Table Size After Reindex

Feb 22, 2015

I'm trying to understand what is happening to one large table.

In a DB SQL 2008R2, I'm trying to track a rapidly increasing DB size. It's due to one table recently added.

Despite the table's no rows increasing its size reduces after a scheduled re-index.

I've recorded the space used by this table by recording EXEC sp_spaceused 'tableName'

NoRows reserved data index_size unused
128864512300384 KB 2290928 KB9432 KB24 KB AFTER reindex
128864515406232 KB 5366184 KB39280 KB768 KBBEFORE reindex

N.B. The only thing I'm aware of happening in the time period is a reindex as part of scheduled task. I could be missing something else happening.

The table has only one Index the PK which is clustered, No Fill factor is specified. The Server Default fill factor =0.

I read fillfactor=0=100 Will always try and fill the pages so space used will be minimised?

After running the reindex the index fragmentation is v.low. I've not recorded the fragmentation before reindex.

I can see the Data is not added in Clustered index order.

SQL Server 2008 :: Data Type And Size Of Each Row

Feb 27, 2015

In my database there is a big table and format is something like this:

CREATE TABLE [dbo].[MyTable](
[aaa] [uniqueidentifier] NULL,
[bbb] [uniqueidentifier] NULL,
[ccc] [nvarchar](max) NULL,
[ddd] [nvarchar](100) NULL,.......etc.........

There are some more columns with more 'nvarchar' (max) and other INT data types. Anyway, I know a page is 8K size. How do I find out how much space does A ROW takes with above datatypes? If users add 5000 Rows per day, how do I figure out how much size the table will increase?

SQL Server 2008 :: TempDB Size Hovering Around 45%

SQL Server 2008 :: Size Limitation For XML Data Type?

Oct 7, 2015

I've never worked with the XML data type in SQL Server, although I know its been there for a few iterations of SQL SErver. Now I've got a situation in which it might store some configuration data as XML, since that's the way it comes. (We had thought about storing the data in a VARCHAR(MAX) field.)

The first question is does the XML data type have a size limitation? For example do you do something like:

ConfigFile XML(1000) NULL

Or is it just something like this:

ConfigFile XML NULL

The second question is persisting the data to a file. As the name I choose for the variable suggests, we want to save the data from a configuration file into a SQL Server database. How do we go about doing that? We'll be developing a C# application, it will read and write the data both from the SQL table and the user's local HD.

SQL Server 2008 :: Finding Backup File Size In Advance?

Mar 8, 2015

My backups are failing sometimes.My db size is around 400 GB and we are taking backup to the remote server. Free size available on the disk is showing 600 GB but my database full backup run more than 10 hrs and failed. The failure reason is there is not enough space on the disk.

What could be the possible failure reasons? It has more than the the database size on the backup server but why it is showed that msg on the job failures. I noticed same thing occurred couple of times in the past.

Is there any way to find how much the backup file will be generate before we run the backup job?

i.e. If we run the full backup of test1 database now, it will generate ....bak file for that test1 db

currently we are using maintenance plan and with compression (2008R2) and the database has TDE enabled

SQL Server 2008 :: Virtual Log Files And Determining Right Growth Size

Any good starting point to understand for a specific db, how many max VLFs are good to have so that it does not cause long startup or backup times?

Also, I need some calculation so that I can identify a best growth parameter I will setup for each database ?

I'm seeing the below msg in errorlog and curious to know the changes (right sizing/growth) to be done? As of now 100 MB of log file growth value is set (refer: [URL] ....)

Database BizTalkMsgBoxDb has more than 1000 virtual log files which is excessive. Too many virtual log files can cause long startup and backup times. Consider shrinking the log and using a different growth increment to reduce the number of virtual log files.

Itthen calls insertTransaction and passes the transaction xml into thatsproc.insertTransaciton then inserts the transactions in the xml, and alsocalls insertParties, passing in the XML snippet
