Is there any way to get size of the individual column in a table?
I know we can use sp_spaceused to get the size of the table. But my question is diiferent. I have a table with 50 columns and approx 2 million rows in it. I wanted to know which column is taking most of the space.
Thanks

View 2 Replies View RelatedI'm trying to determine how much space some tables use (SQL2000), and I found 2 suggestions posted earlier, but can't get them to work for me.
The first was
"Right click on the DB in Enterprise Manager, select view then taskpad."
When I try that, I get some of the tables displayed with the info I want, but I can't see them all and can't scroll down beyond the first 22 tables in the database.
The second suggestion:
exec sp_msforeachtable @command1="print '?'",@command2="sp_spaceused '?'"
It says "command copleted successfully, but where does the output to this go ?? Is there something other than "print" I should use ?

I need to change the size of a column of a table from char(255) to char(500). I used the line:
alter table table_name alter column column_name char(500)
When I run that command, I get a message that it was sucessful. However, when I try to enter data into the changed column, the number of characters I can enter is still 255. I check the information schema for the column and the 'character_maximum_length' field is 500.
What is the problem here? Is the maximum allowable length for char 255? How can I get a column to have 500 characters?
Does null column take storage in table ? I created the following table:
drop table [dbo].[TBL_orig]
CREATE TABLE [dbo].[TBL_orig](
[1] [bigint] NOT NULL,
[2] [bigint] NULL,
[3] [bigint] NULL,
[4] [bigint] NULL,
[5] [float] NULL,
[Code] ....
Does null value will take a place even no data insert to this columns and if yes this answer is 4 mb is logical gap ?

I need to find a table and column name from some given data. I know what data i want to edit, I just need to know where it is located and the database is too big to manually go through. It is Microsoft sql server 2000. Any help is appreciated.

The intention is, a query which suggests some columns to be indexed; Based on the usage of the column by the queries that run on server.
i have written query to find out column names of a table in the database .
SELECT t.NAME AS TABLEName
,SCHEMA_NAME(schema_id)+'.'+c.name AS ColumnName
FROM sys.tables t
INNER JOIN sys.columns c ON c.object_id = t.object_id
WHERE OBJECT_NAME(c.object_id) LIKE '%Message%'ORDER BY t.NAME
So far i got the Expected result but what ever column i am looking i want to find out the Dependency of column realted tables. by executing the above query i am getting table name and column name. How can i get the column related dependent tables.

(Above is a hint as to one way)
I had to do this because a system was sending out a not very impressive email to users ad we couldn't find what was triggering it.

What causes SQL Server 2000 to create tables with default column sizes of 8000 for a varchar datatype??
I would assume this can cause significant performance problems.
(see attached)
I am able to get reports going with tables sized properly. They look fine on the ReportServer website and I adjust the column widths so that the headings and data look nice. When I set up a subscription to be delivered by "Report Server E-Mail," though, the table formattings get completely distorted.
In particular, I have two tables, with some column headers being two short words (e.g. Max Height). When rendering on the site, I adjust the columns so the full column header is visible on one line. When I receive the email and read it in Outlook, the header row is now about twice as tall and everything is scrunched together. Both the headings and the data in the fields do not format the same as on the website.
The two tables tend to actually have the exact same width in the email version, although occasionally they are a little different (in the web version one is about half as wide as the other). I have tried just making the columns bigger and that has not worked. I've tried making the font sizes smaller, which didn't work. If I do that, leaving the columns the same width, the email version just gets scrunched into a smaller area with the same text-wrapping problems.
If I open the email in a browser (in a web mail interface) the report renders perfectly as on the site.
I have almost all the default settings, and haven't been messing around with page sizes and things like this (except after, to see if that would fix the problem).
Any ideas, similar experiences, or suggestions? If there is a book I should read or any reference you could point me to in order to figure this out would be helpful. I haven't been able to understand this either using web searches or the two SQL reporting services books I have.
i need to check that the column exist in the table if yes the update/insert value in the column else i need to add the new column like new browser name in the table.

View 2 Replies View RelatedI am having a main table and temptable.
Every sunday, new data will be loaded from temptable to main table. I have to make sure that, duplicates does not get loaded from temptable to maintable.
For example, if last sunday a record gets loaded from temp to main. If this sunday also the same record is present then it means that is a duplicate.
The duplicate is decided on below scenario
select 'CodeChanges: ', count(*) from CodeChanges a, CodeChanges_Temp b
where a.AccountNumber = b.AccountNumber and
a.HexaNumber = b.HexaNumber and
a.HexaEffDate = b.HexaEffDate and
a.HexaId = b.HexaId and
[Code] ...
Yesterday (Sunday) , data from temp got loaded onto maintable but with duplicates.
There is a log which just displays number of duplicates.
Yesterday the log displayed 8 duplicates found. I need to find out the 8 duplicates which got loaded yesterday and delete it off from main table.
There is a column in both tables which is 'creation date and time'. Every Sunday when the load happens this column will have that day's date .
Now i need to find out what are all the duplicates which got loaded on this sunday.
The total rows in temp table is : 363
No of duplicates present is : 8
I used below query to find out the duplicates but it is returning all the 363 rows from the maintable instead of the 8 duplicates.
Select 'CodeChanges: ', * from CodeChanges a where
exists
( Select 1 from CodeChanges_Temp b where
a.HexaNumber = b.HexaNumber and
a.HexaEffDate = b.HexaEffDate and

Few colums only metioned below

I have created some dynamic sql to check a temporary table that is created on the fly for any columns that do contain data. If they do the column name is added to a dynamic sql, if not they are excluded. This looks like:
If (select sum(Case when [Sat] is null then 0 else 1 end) from #TABLE) >= 1 begin set @OIL_BULK = @OIL_BULK + '[Sat]' +',' END
However, I am currently running this on over 230 columns and large tables 1.3 mil rows and it is quite slow. How I can dynamically create a sql script that only selects the columns in the table where there is data in a speedier manner. Unfortunately it has to be on the fly because the temporary table is created on the fly.
Can't seem to make this SQL query work!
Given one table, Table1, with columns Key1 (int), Key2 (int), and Type (varchar)...
I would like to get the rows where Type is equal to 'TypeA' and Key2 is Null that do NOT have a corresponding row in the table where Type is equal to 'TypeB' and Key2 is equal to Key1 from another row
So, given the data
**KEY1** **Key2** **Type**
1 NULL TypeA
2 5 TypeA
3 1 TypeB
4 NULL TypeA
5 NULL TypeB
I would like to return only the row where Key1 = 4 because that row meets the criteria of Type='TypeA'/Key2=NULL and does not have a corresponding row with Type='TypeB'/Key1=Key2 from another row.
I have tried this and it doesn't work...
SELECT t1.Key1, t1.Key2, t1.Type
FROM Table1 t1
WHERE t1.Key2 IS NULL
AND t1.Type LIKE 'TypeA'
AND t1.Key1 NOT IN
(SELECT Key1
FROM Table1 t2
WHERE t1.Key1 = t2.Key2
AND t1.Key1 <> t2.Key1
AND t2.Type LIKE 'TypeB')
I have a SQL text column from SP_who2 in table #SqlStatement:
like 1row shown below :
"update Panel set PanelValue=7286 where PanelFirmwareID=4 and PanelSettingID=9004000"
I want to find what table and column names are in the text ..
I tried like below ..
Select B.Statement from #sp_who2 A
LEFT JOIN #SqlStatement B ON A.spid = B.spid
where B.Statement IN (
SELECT T.name, C.name FROM sys.tables T
JOIN sys.columns C
ON T.object_id=C.object_id
WHERE T.type='U'
)
Something like this : find the column names and tables name
Hi ,
I have two tables within a SQL database. The 1st table has an identified column and column which lists one of more email identifers for a second table,
e.g.
ID Email
-- ----------
1 AS1 AS11
2 AS2 AS3 AS4 AS5
3 AS6 AS7
The second table has a column which has an email identifier and another column which lists one email address for that particular identifier, e.g.
ID EmailAddress
--- ------------------
AS1 abcstu@emc.com
AS2 abcstu2@emc.com
AS3 abcstu3@emc.com
AS4 abcstu4@em.com
AS5 abcstu5@emc.com
AS6 abcstu6@emc.com
AS7 abcstu7@emc.com
AS11 abcstu8@emc.com
I need to create a stored procedure or function that:
1. Selects an Email from the first table, based on a valid ID,
2. Splits the Email field of the first table (using the space separator) so that there is an array of Emails and then,
3. Selects the relevant EmailAddress value from the second table, based on a valid Email stored in the array
Is there any way that this can be done directly within SQL Server using a stored procedure/function without having to use cursors?
Many Thanks,

For our ETL process, we maintain a TransformationList table that has the source view and the destination table. Data is copied from the view into the table (INSERT INTO). I am trying to find column names in the Views that are not column names in the associated Table.
In the below example, want to end up with three records:
1, View1, Column4
2, View2, Column4
2, View2, Column5
I have it almost working, except that there is a table, ChangeColPrefix table, that is used by the ETL process to change some of the view's column name prefixes. Some of the source views have column names with prefixes that do not match the destination table column names. Say view SouthBase has all the column names prefixed with SB - like SBAcct, SBName. And the Destination table of Area District has ADAcct, ADName. There would be a row in the ChangeColPrefix for SouthBase, SB, AD, 1, 2 that would be used by the ETL process to create the INSERT INTO Area District From SouthBase.
I need to use this ChangeColPreifx to find my unmatching columns between my source views and destination tables. With out that table SBAcct and SBName from SouthBase will not appear to match the columns of ADAcct and ADName, but they do match.
I want to end up with these three records as non-matching:
View1, Column4
View2, Column4
View2, Column5
View1 has Salumn2 and View2 has Salumn5, and they must be changed to Column2 and Column5 as per the ChangeColPrefix table before running the Select from INFORMATION_SCHEMA.COLUMNS EXCEPT Select from INFORMATION_SCHEMA.COLUMNS looking for unmatched columns.
/***** Set Up Test Data *****/
-- Create 2 test views
IF EXISTS(SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[View1]'))
DROP VIEW dbo.[View1]
GO
CREATE VIEW View1
AS SELECT '1' AS Column1 , '2' AS Salumn2 , '4' AS Column4;
[Code] ....
