Table Size Info
Apr 24, 2008Does TSQL (2005) offer a way to retrieve a given table's total size (data size vs index size)? Would like to be able to get at this info using TSQL (not management studio).
thanks

Is There A System Table With Timestamp Info Or DTS Job Info?
May 7, 2007I want to be able to see when records have been added to a table. The issue is we have a DTS job scheduled to run every night. The developer who wrote it password protected it and doesn't work here anymore. I want to add a step to this series of DTS jobs and want to run it just prior to his job. Is there a way to see when the records are being added or when this job is being run? Thanks again, you guys are the best.

Database Size Info Without Cursors Or Temp Tables
Jan 22, 2004I 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 Admin 2014 :: Possible To Find Table Size And In That Table Each Row Size
Jun 10, 2014It is possible to find table size and in that table each row size.
View 4 Replies View RelatedDelete Rows In One Table By Referencing Another Table Info
Sep 16, 2004I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.
Here is a basic breakdown of what I am trying to do:
Table1 (the table where the rows need to be deleted from)
Column_x (Holds the id that is unique to the various rows of data - User ID)
Table2 (Holds the user information & has the associated ID)
Column_z (holds the User ID)
I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.
Code:
SELECT Column_z
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z <> Column_x
This did not seem to do what I needed, it did not delete any rows at all.
I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2
Then I tried another scenerio that I also needed to do:
Code:
SELECT Column_z, Column_a
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z = Column_x AND Column_a='0'
'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.
Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.
Any ideas on what I am doing wrong here?
Not Sure How To Get Info From Other Table
Aug 31, 2005I am having problems with my store procedure displaying my last column name which is "DISPLAY_CATEGORY_DESC". I am trying to display the description from another table. But in order to get to the description I have to go through 2 tables. The tables look like something like this.
First TableTABLE_CATEGORY
PRIMARY_KEY = DIR_CATEGORY_ID = 5000
Column Name
DIR_CATEGORY_LVL_ID1 = 100
DIR_CATEGORY_LVL_ID2 = 200
DIR_CATEGORY_LVL_ID3 = 300
Second TableTABLE_CATEGORY_DESCRIPTION
PRIMARY KEY DIR_CATEGORY_LVL_ID1 = 100
Column Name
DESCRIPTION = "Car Model Company"
This is my DISPLAY_CATEGORY_DESC
Not sure how to get to this description. Thanks for your help.
select cwebs.SESSION_ID, webs.ENTERED_DATE, cwebs.DIR_CATEGORY_ID, DISPLAY_CATEGORY_DESC

Table Size And Database Size
Mar 2, 2008Hi,
i use this script that show me the size of each table and do the sum of all the table size.
SELECT
X.[name],
REPLACE(CONVERT(varchar, CONVERT(money, X.[rows]), 1), '.00', '') AS [rows],
REPLACE(CONVERT(varchar, CONVERT(money, X.[reserved]), 1), '.00', '') AS [reserved],
REPLACE(CONVERT(varchar, CONVERT(money, X.[data]), 1), '.00', '') AS [data],
REPLACE(CONVERT(varchar, CONVERT(money, X.[index_size]), 1), '.00', '') AS [index_size],
REPLACE(CONVERT(varchar, CONVERT(money, X.[unused]), 1), '.00', '') AS [unused]
FROM
(SELECT
CAST(object_name(id) AS varchar(50)) AS [name],
SUM(CASE WHEN indid < 2 THEN CONVERT(bigint, [rows]) END) AS [rows],
SUM(CONVERT(bigint, reserved)) * 8 AS reserved,
SUM(CONVERT(bigint, dpages)) * 8 AS data,
SUM(CONVERT(bigint, used) - CONVERT(bigint, dpages)) * 8 AS index_size,
SUM(CONVERT(bigint, reserved) - CONVERT(bigint, used)) * 8 AS unused
FROM sysindexes WITH (NOLOCK)
WHERE sysindexes.indid IN (0, 1, 255)
AND sysindexes.id > 100
AND object_name(sysindexes.id) <> 'dtproperties'
GROUP BY sysindexes.id WITH ROLLUP) AS X
ORDER BY X.[name]
the problem is that the sum of all tables is not the same size when i make a full database backup.
example of this is when i run this query against my database i see a sum of 111,899 KB that they are 111MB,but when
i do full backup to that database the size of this full backup is 1.5GB,why is that and where this size come from?

How Would You... (binary Info In A Table)
Sep 15, 2007I have run into a challenge that I'm not sure how to best solve. I'dappreciate any opinions or input.I am working with a third party database. They are storing some datathat I need to use in a binary field. I've got the code to parse thebinary and reconstruct what I need. Unfortunately, there might bemultiple "entries" stored in a single binary field. a certain byte,let's just say the first, will always be the count of "entries" inthis particular SQL entry.An example:then entry might be:0x01000012341234where 12341234 is the data entry that I will parse.Another possible entry is:0x03000012341234567856789ABC9ABCThe first byte indicates that there are three data values I want toparse out:12341234567856789ABC9ABCThe portions of the binary I need are always the same length and theremay be from 1 to ~100 of them. (usually 1 if it matters.)The big question:How could a SQL query return an entry for each of the "entries" in thebinary field? For the second example I would want three entries in myresults, each row returning a different section of the binary data.For the first, only one row. I'll be querying the set and expecting toget back more results than the number of entries in the set.I haven't really tried much with this yet, (other than some mentalcalisthenics were I fell down onto the mat pretty hard), so just somedirection on where to begin would be helpful.(Yes, I understand that the difficulty is that this data shouldn't bestored this way, but there is not much I can do about that.)Thanks...James FraserJoin Bytes!

May 7, 2007Hi There
I am trying to troubleshoot deadlock issues.
The dead lock is with a RID.
Now from various links i have established that you have to use DBCC PAGE() with relevant info to get more information, i get back a object and index id, m_objid.
However i dont know how to get the tablename form here, msdn simply says that it is an allocation id not and actual table id, so how can i from here get to table information?
All i am trying to figure out is which table is affected fromt he RID dealock, but that does not seem to be a simple process.

basically if the record id exists skip to the next line and so forth, I am able to import everything just fine but I cannot get the WHERE condition to acually work.
INSERT INTO TABLE2 (COL1, COL2, COL3) SELECT COL1, COL4, COL7 FROM TABLE1 WHERE table2.col1 <> table1.col1
this is what my actual code is
INSERT INTO USER_INFO (fpu_id,FIRSTNAME, LASTNAME, BOXNUMBER) SELECT id,first,last,box FROM stmailbox WHERE stmailbox.id <> dbo.USER_INFO.USERID
this is the actual error that I get.

Amending Query To Get Info From New Table
Oct 19, 2013I used to use this code to extract coupon usage from two tables orders and coupons
select distinct o.OrderDate, p.SKU, c.CustomerID, c.CustomerLevelID, c.Email, c.FirstName, c.LastName from customer c
join dbo.Orders_ShoppingCart os with (NOLOCK) on os.CustomerID = c.CustomerID
join dbo.Product p with (NOLOCK) on p.ProductID = os.ProductID
join dbo.Orders o with (NOLOCK) on o.OrderNumber = os.OrderNumber
[code]....
Following a database upgrade the Coupon Code is no longer used. Instead there are two new SQL tables called Promotions and PromotionsUsage.. The link between the two tables are
ID in Promotions
and
PromotionID in PromotionUsage
Both are the same value. So in order to see new orders for coupon usage how would I change this line in the original SQL to retireve this?

Update Certain Fields In User Group Table With New Info
Apr 28, 2014I've just written a query that successfully brings back the data from one table based on the information from another. Basically we have been given a table of information and need to update certain fields in our user_group table with the new info.
Here is the SELECT statement
SELECT user_group.id, user_group.name, user_group.description, Consultants.description AS Expr10, user_group.btype, user_group.rootmenu,
user_group.intra_user, user_group.primary_g_id, user_group.fname, user_group.lname, user_group.ntlogon, user_group.lang_id,
user_group.[external], user_group.title, user_group.work_tel, user_group.work_fax, user_group.work_ext, user_group.mobile, user_group.sex,
user_group.add2, user_group.add3, user_group.town, user_group.county, user_group.pcode, user_group.private_flag,
[code]....
We want to update the 'description' on the user_group table with the 'description' from the 'consultants' table. To test this, we only want to write the UPDATE so that it changes the description where the name is 'Adam Froth. The UPDATE statement that we've written is
UPDATE user_group
SET user_group.description = Consultants.description
FROM user_group
INNER JOIN Consultants
ON user_group.description = consultants.description
WHERE name like 'Adam Froth%'
but it keeps erroring and saying that it could 'Not be bound'.
Updating MSSQL Table With Info From Excel Sheet
May 11, 2007MSSQL noob here. Sorry guys, but I really need some help.
I have a MSSQL (2000) database and a Products Table. Now, there was three columns used for pricing that I was not able to populate on the initial usage. So I exported the table as an Excel document, and got rid of everything except the UID (unique identifier column) the Name, and the Three columns, so that the customer could take their time in filling out the information.
Ok, so These are what are common to both the MSSQL database and the Excel sheet
column uid = unique id integer
column Name = text
column eBay = number
column PriceGrabber = number
column Amazon = number
So, any idea how I can update my Products Table with this?

How To Make A Temp Table Using Info Fromtwo Tables
Mar 8, 2008I have one database named StudInfo. It has two tables named StudentInfo, and GradeInfo.
StudentInfo conntains 4 columns. The 1st one is StudentID (PK) int, LastName varchar(10), FirstName varchar(10), and PhoneNumber int.
GradeInfo contains 4 columns also StudentID (FK) int, GradeID varchar(10), Grade int, Date Datetime.
What I would like to know is how using a T-sql query I could make a temp table with studentID, LastName, FirstName, and then the average of all the different types under GradeID. As of right now I have been limiting the names that are put into GradeID to Homework, Daily, Test, Quiz, and Bonus. When I say average I mean the average of all Homeworks under one studentID, and all Daily under one studentID... etc. I would like the info returned for each student in studentID. Allow Nulls has been turned off.
Never assume someone knows what you are talking about.

I also set table RI to have cascade delete. I faced problem that, when I delete record in parent table, it would cascade delete child table. Trigger in child table fired and try to update stock qty. However, in this case, trigger unable to locate parent table record anymore.
How to overcome this? I can't move my stock update code to other place since I got to update stock if any changes happen to child table.
Please advice.

Transact SQL :: Left Join To Get Info From A Table With Foreign Keys
Sep 13, 2015I am still new to SQL and I am having trouble obtaining the results I need from a query. I have worked on this command for some time and searched the internet but cannot seem to still get it correct.
I have a table called Patient. It's primary key is pat_id.
I have a second table called Coverage. It has no primary key. The foreign keys are pat_id, coverage_plan_id, and hosp_status.
I have a third table called Coverage_History.  It has a primary key consisting of pat_id, hosp_status, copay_priority, and effective_from.Â
I want to get the pat_id and all the coverage information that is current.  The coverage table contains specific insurance policy information.  The coverage_history table will indicate the effective dates for the coverage. So the tables could contain something like this:
Patient (pat_id and lname)
P123Â Monto
P124Â Minto
P125Â Dento
P126Â Donto
Coverage (pat_id, coverage_plan_id, hosp_status, policy_num)

P126Â Â OPÂ Â 1Â Â 20150801Â BCBÂ Â Â Â 20160101
select p.pat_id, p.lname, ch.coverage_plan_id, ch.hosp_status, ch.effective_from, ch.effective_to, ch.copay_priority,

    left join
  ( coverage_history ch left join coverage c on ch.coverage_plan_id = c.coverage_plan_id and ch.patient_id = c.patient_id and

Inporting Attached Excel File Into Existing Table Adding Info
Jul 25, 2005Hi all,I have a problem and need some ideas.What I have done: I created a page to upload an excel file into a SQL Server table along with some customer info (from the login, day, etc.). This excel file contains several rows (some of them may be blank) and columns (also some may be blank). The file is stored in an image object.The file will be checked (they want to do it manually, because contents is a problem). If they say it is OK, I want to run a program to add a record into an existing table with the request no. (from the first table, where the object is stored) and all the information available from the filled rows (first row is header). I have a column, which can be checked, if the row contains data or not.Any ideas?I know how to read from and write the contents of the object to a field in the SQL table. Can I use this?Thanks for any idea / code / link.
