Is there any possibility to trace, most used column in every table on the SQL server?
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 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')
Create Table Sample (ID int not null primary key, RefID int , SeqNo int , Name varchar(10) )
insert into Sample
select 1, 1000, 1, 'Mike'
union
select 2, 1000, 2, 'Mikey'
union
select 3, 1000, 3, 'Michel'
union
select 4, 1001, 1, 'Carmel'
union
[code]....
select * from SampleI have here sample data given. What I want to do is, I want to check the RefID which is not having proper order of sequence number. If you see the RefID 1000, 1001 they are having properly sequence order in SeqNo field. But it is not in RefID 1002. RefID 1002 does not have proper order. It is because user has deleted a row which was having seqno 2. So i want to get what are all the RefID's are not having properly sequenced. So that I would be able to know these are all the RefID's are affected by delete statement that was done by user.
I have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores'
storeid doc article storeid doc article
ALL 0010 001 101 0010 001
ALL 0010 002 101 0010 002
ALL 0011 001 102 0011 002
ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".
I have a database of 900+ tables with around 3000 SPs, and views. Manually I reviewed few tables and found that tables are not referenced with FK and I applied few. There are lots of tables and SPs using them in join statement, Is there any way with which I can get each tables missing references, any DMV or other manual script which tells about this?

I need to find all tables which has a join (either inside an sp, view, etc) with my given table in a db.
sys.dm_sql_referencing_entities doesn't work here.

View 7 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

Select B.Statement from #sp_who2 A
LEFT JOIN #SqlStatement B ON A.spid = B.spid
where B.Statement IN (

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] ....
