Can we use a sql function() in create index as below is giving error , what would be work around if cannt use the function in below scenario
CREATE NONCLUSTERED INDEX [X_ADDRESS_ADDR1_UPPER] ON [dbo].[ADDRESS]

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
I would like to create a function that take a value and run some logic and output the value
I have a table like this
Table A
value
*
001
004.00
3.0
1.22
Logic I want to run is
The value that you are passing is numeric and numeric with only decimal 0 value, and then convert it to integer otherwise leave as it is
So if I run a query something like this
Select value, fn_convertointerger(value) as converted_value from TableA
I will get
Value converted_value
* *
001 1
004.00 4
3.0 3
1.22 1.22
2.02 2.02
4.000 4

How can I create a function like this to convert specific numeric value?

I need to create a Clustered Index (CI) on a very large SQL Server 2012 database table. This table has about approximately 10 billion rows, 500 GB in size. The job ran for about 20 hours into it and then fails with error: "Out of disk space in tempdb". My tempDB size is 1.8TB, but yet it's still not enough.
Here is my script:
CREATE CLUSTERED INDEX CI_IndexName

WITH (MAXDOP= 4, ONLINE=ON, SORT_IN_TEMPDB = ON, DATA_COMPRESSION=PAGE)
ON sh_WeekDT(Day_DT)

I understand that minimal logging can occur on a non clustered indexed heap as long as [URL] ...
*not replicated
*tablock is used
*table is empty
The following test seems to contradict this
In the test I create a non indexed heap, insert some record and check the log, then repeat the test on an indexed heap.
The results suggest that even though the conditions for minimal logging into a indexed heap are met, minimal logging is not happening although it does happen on an non indexed heap. What am I doing wrong?
CREATE DATABASE logtest
GO
USE logtest
GO
CREATE TABLE test (field varchar(100))

I am selecting the count of the students in a class by suing select COUNT(studentid) as StCount FROM dbo.student But I need to use a case statement on this like if count is less than 10 I need to return 'Small class' if the count is between 10 to 50 then I need to return 'Medium class' and if the count is more than 50 then 'Big class'.
Right now I am achieving this by the following case statement
SELECT 'ClassSize' = CASE WHEN Stcount<10 THEN 'Small Class'
WHEN Stcount>=10 and StCount<=50THEN 'Medium Class'
WHEN Stcount>50 THEN 'Big Class'
END
FROM(
select COUNT(studentid) as Stcount FROM dbo.student) Stdtbl
But can I do this with just one select statement?

i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename]
SET [No] =
CASE
WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa'
ELSE 'Null'
END

Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.

I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
Hi all..
I tried too much to create FULL TEXT INDEX by using SQL Server 2005 Management Studio Express, it returns this ERR MSG:
Informational: No full-text supported languages found.
Informational: No full-text supported languages found.
Msg 7680, Level 16, State 1, Line 1
Default full-text index language is not a language supported by full-text search
This problem dos not come when I use Microsoft SQL Server 2005 Management Studio, to create FULL TEXT INDEX!
My DB collation is: "Arabic_CI_AS"
But I dont need this, I can use English Language.
Please, what can I do?
Hi
I'm trying to use a udt in a table creation, and everything works as expected, right until the moment where I rightclick on [Indexes] to create a new index.
Then I get this error:

GO
Create table [TestSchema].[Periode3]
(
Periode3_UID uniqueidentifier NOT NULL ROWGUIDCOL,
rowVersion timestamp NULL,
owner uniqueidentifier not null,
validFrom datetime
NOT NULL CONSTRAINT

);
Alter table [TestSchema].[Periode3]
add PeriodeType [TestSchema].[type_TestType];
now if I replace the 2 last lines with:
Alter table [TestSchema].[Periode3]
add PeriodeType uniqueidentifier;
everything works as expected.
Where did I go wrong ?

Hi All,
I 'm working to improve some sql performance.
One of the major syntax inside the SELECT statment is ..
WHERE FIELDA IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='A') AND
WHERE FIELDB IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='B') AND
WHERE FIELDC IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='C') AND
WHERE FIELDD IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='D') AND
WHERE FIELDE IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='E') AND
WHERE FIELDF IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='F')
(It's to compare the field content with some user input parameter inside a parameter table... )
I think properly is that the SELECT ... IN is causing much slowness in the sql statement. I have indexed FIELDA , FIELDB, FILEDC etc and those PARAVALUE and PARATYPE in the PARATABLE table. But perfromance is still slow and execution takes >20 seconds for 200000 rows of records.
Do any one know if still any chance to improvide the performance like this?
Much Thanks,
Andy

I have a query which is primarily a victim of blocking and a blocker itself for other queries. I studied the plan for this and it shows a 42% cost on CI insert operation. The insert is happening on a table (Table A) that has a PK. This PK is not a running number. It is also a business key (primary key) in another master table (Table B).
My understanding is that the cost is heavy because -
1, this PK is not an incremental number. It could be any number not in a sequence.
2. while inserting into CI, there must be a scan happening to find out the location where the index will be inserted.
How can I reduce the cost?
1. Should I go for partitioning of this table Table A? I am trying to do this but I am not able to find any suitable partition key looking at the JOINS and filter clauses where this table is being used in the applicaiton.
2. Should I introduce a surrogate key (running number) as a primary key so that CI is faster ?
I am trying to create a unique index on a table such that the combination of 2 columns is unique. How do I go about that?
View 5 Replies View RelatedSo I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.
From Books Online:
• This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.
• The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.

View 1 Replies View RelatedI have a clustered index that consists of 3 int columns in this order: DateKey, LocationKey, ItemKey (there are many other columns in this data warehouse table such as quantities, prices, etc.).
Now I want to add a non-clustered index on just one of the other columns, say LocationKey, like this:
CREATE INDEX IX_test on TableName (LocationKey)
I understand that the clustered index keys will also be added as key columns to any NC indexes. So, in this case the NC index will also get the other two columns from the clustered index added as key columns. But, in what order will they be added?
Will the resulting index keys on this new NC index effectively be:
LocationKey, DateKey, ItemKey
OR
LocationKey, ItemKey, DateKey
Do the clustering keys get added to a NC index in the same order as they are defined in the clustered index?
I have a dataset that I need to search for a maximum value of a specified index.
Example of dataset:
Heat Index Heat # Frame Window
1 584 110 110
1 584 102 109
1 584 95 106
1 584 190 112
2 586 100 100
2 586 150 120
2 586 170 130
2 586 112 126
I need to find the maximum value of Frame for each heat and the maximum value of Window for each heat. As you can see each heat has several data points.
Is there a way I can send the dataset to a function? I could then use a loop to test for the maximum of Frame and the maximum of Window for each heat.
Could I use an array?

View 9 Replies View RelatedI have a view that joins a dozen tables with a million rows added per year by an application. I want to materialize it. The view is always filtered by date first on reports, then there are a few key transaction keys, but then many other fields required to make each row unique. I don't want to add these columns since they are large, many, not used for sorting or filtering, and may not define uniqueness in a future application design. I need a uniqueifier that is application agnostic. I prefer a bigint. So to store the materialized view ideally for reporting, I want to add the following clustered index to materialize the view:
CREATE unique CLUSTERED INDEX idx1
ON [dbo].[myview](myDate, key1, key2, key3, id bigint identity(1,1) NOT NULL)
And I get this error:
Msg 102, Level 15, State 1, Line 3
Incorrect syntax near 'bigint'.
Can I do what I want? If so, how?
Consider following code:
SELECT e1.EntityIdentity as CompanyID
FROM dbo.Entitye1 --company
JOIN dbo.EntityAssociationea
ON e1.EntityID = ea.EntityID1
JOIN dbo.Entitye2 --user
ON ea.EntityID2 = e2.EntityID
This query occurs as a sub-query in many stored procedures where exists a WHERE clause that includes CompanyID IN (above query).
Since dbo.Entity and dbo.EntityAssociation change infrequently I thought that an indexed view would really improve performance. But I've found one of the seemingly undocumented Microsoft features when trying to create the clustered index and get the following error msg:
Msg 1947, Level 16, State 1, Line 1
Cannot create index on view "ROICore.dbo.vEntityEntityAssociation_CompanyUser". The view contains a self join on "ROICore.dbo.Entity".
I really need to improve performance on this subquery. Entity currently has over 20m rows and EntityAssociation over 35m rows and both are growing.
How to improve performance? Indexes on both tables for the most part give index seeks, but I thought my saviour might be the index view. Obviously this will not work.

I have 2 databases on a separate instance. I want to script out all indexes from database1 then execute it on database2.
How to accomplish this task efficiently.
We have a table to 100M rows and up until now we were fine with an non clustered index a varchar(4000) because we never went above 900 bytes (yes it is a bad design).We have the need to support international character sets now so the column was updated to nvarchar(4000) and now we have data past the 900 byte limit.
The data is long, seems useless but is needed by the business and they need to be able to search "where bigcolumn like 'test%'". With an index, even with a huge amount of data, it was 'fast'. Now of course without an index it is unusable. The wildcard is always at the end of the search. I made a full text index on the column and basic queries such as: select * from ourtable where contains(bigcolumn, 'AReallyLongStringofTextHere') works fine unless there is a space in the data. We loose thousands of returned rows because of spaces in the data.
I have tried select * from ourtable where contains(bigcolumn, '"AReallyLongStringofTextHere that includes spaces"') but not all of the data is returned. I get 112 rows with the contains statement. The table scanning statement of "select * from ourtable where bigcolumn like 'AReallyLongStringofTextHere that includes spaces%' returns 1939 rows.I understand that a full text index is breaking the long string up since it contains spaces. Is there a way to retain the entire string as 1 index entry or is there a way to fix my query to return all of the rows?
