Need help,
I'm a newby to SQL and looking for how-to-help.
I have an existing DB and within a certain table, I have created a new Column via Studio manager, but need help with the following:
Need to make the new Col "Unique, and Indexed" but cannot see anywhere in studio manager interface to do it.
Thanks.
I'm not able to create indexed views,
which are clustered-indexed on only 1st field.
I can't even INCLUDED other fields.
I need the entire view to exist as a physical table. (for performance)
Please let me know the work around.
Thanks..
I have the following table (Table does not have unique key id )

May be we may do by dense_rank or Row_Number, but I couldn't get the exact query to produce based on the above table values. Â There are some duplicates in the table(which are not duplicates as per the Business). For those duplicated Unique ID should be same(Marked in Orange Color which are duplicates).Â
Hi, can anyone guide me on how to create a unique field with SqlExpress and VC#.net?
I know how to create primary key with identity, however I need to create another unique column for "email". I have search high and low for a solution but found none, the closest i got is unique constraint which I've not idea what's that.
Please help, else I have to always do a duplication check before inserting new records.
Many thanks.
I am working with a table in SQL server. I have a column that I want to designateas an identity column. I am not able to do this, because the field for "Identity Specification" is not editiable.
What I did was I went to sql server, right clicked and selected "Modify".The column properties dialog box/edit grid is then displayed with attributesthat I can modify.
There are two major nodes in this dialog box. One is named "General" and the otheris named "Table Designer". I expand the "Table Designer" node and then go to the node labeled "Identity Specification" It is here where I would like to edit thevalues.
The values that are listed for edit are listed below. BUT, the problem is thatI can place my cursor in those fields, but I am not able to change/edit them.Can anyone tell me what the problem is here? and how I can fix it?
+Identity Specification (Is Identity) Identity Increment Identity Seed
Hi all,
I am trying to add a unique index/constraint on a column that allows NULL values. The column does have NULL values and when I try to create a unique constraint, I get the following error.
CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 9. Most significant primary key is '<NULL>'.
Are'nt you allowed to create a UNIQUE constraint on a NULL column? Books Online says that you are allowed to create a unique constraint on NULL columns, then why am I getting this error.
Any help would be appreciated.
Thanks,
Amir
Hello ,
1.Is there a way to generate an .sdf (SQL CE DB) from an existing SQL Server 2005 DB?
So that the sdf file has the same tables and data as SQL server 2005 DB.
2.Is there a way to copy data in Excel file to an .sdf file (SQL CE DB)?
Thanks,
Rookie
I am sorry if this is the wrong forum for this question but I can not find better fit.
I am using Visual Studio 2005 to write an asp.net web site which includes an SQL data base. In the databaseI have a table called 'ACCOUNTS' which has primary key column called 'ID' and a nvarchar column called 'Name'.
I want the values in the 'Name' column to be unique in the table so that all accounts have unique names. I don't want to make the 'Name' column the primary key because I want people to be able to change the name of their account after it has been created.
It seems to me there must be some way to add such a constraint to the table but I can find none. I have searched the documentation and seen loads of references to unique columns but I can't find any way to set a column to unique thru the IDE (or any other way). Can anyone help me?
Thanks in advance for any help.
Hi,
While creating an indexed view with the command :
create unique clustered index idx_atrid on account_transactions (policy)
there is a check constraint on the policy column of the tables used in this view.
The following error is encountered
Cannot index the view 'test.dbo.account_transactions'. It contains one or more disallowed constructs.
Can anyone help?

I have to get this done and seriously don't know where to start.
Do HELP me out .Thank You.
I am working on creating a report which is retrieving data from a SQL 2005 database and being displayed in a C#.net web page. Presently, I am binding the dataset to a ASP:Gridview on the web page.
I am currently retrieving most of the needed fields using the following SQL statement:PROCEDURE [dbo].[pr_getReportTickets] @DateCreated nvarchar(15) ASBEGIN
-- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
-- Insert statements for procedure hereSELECT tbl_Queue.num_TicketNumber AS TicketID , tbl_Users.str_Name AS Technician , tbl_Queue.str_QueueLocator AS TechNTID , tbl_Queue.dat_ReceivedRequest AS dateCreated , tbl_Queue.dat_DueDate AS DueDate , tbl_Queue.str_TaskName AS TicketTitle , tbl_Queue.str_Requestor AS RequestorNTID --, I need most current dat_TimeStamp from tbl_Notes here for this record --, I need most current int_PercentComplete from tbl_Notes here for this record --, I need to sum up all of int_MinutesWorked fields from tbl_Notes here for this record , MasterEmp.dbo.fn_FormatFullName(tbl_employee.str_fname, tbl_employee.str_lname) AS RequestorName , tbl_Queue.str_TicketType AS TicketType , tbl_Status.str_TaskStatus AS TicketStatus , tbl_Severity.str_Priority , tbl_Complexity.str_Complexity , tbl_Severity.str_Priority + N' / ' + tbl_Complexity.str_Complexity AS Priority , tbl_Queue.dat_CompleteDate as DateCompleted
FROM dbo.tbl_Queue LEFT OUTER JOIN MasterEmp.dbo.tbl_employee AS tbl_employee ON dbo.tbl_Queue.str_Requestor = tbl_employee.str_ntid LEFT OUTER JOIN tbl_Users ON tbl_Queue.str_QueueLocator = tbl_Users.str_ntid LEFT OUTER JOIN tbl_Status ON tbl_Queue.num_Status_CD = tbl_Status.num_Status_CD LEFT OUTER JOIN tbl_Severity ON tbl_Queue.str_Severity = tbl_Severity.str_Severity LEFT OUTER JOIN tbl_Complexity ON tbl_Queue.int_ComplexID = tbl_Complexity.int_ComplexID
WHERE (dbo.tbl_Queue.dat_ReceivedRequest > CONVERT(DATETIME, @DateCreated, 102))
ORDER BY TicketType, tbl_Queue.str_Severity
I also have another table called tbl_Notes. This table contains an unlimited quantity of records for every “num_TicketNumber�. This table contains the following fields: num_TicketNumber, str_TechRep, str_Notes, dat_TimeStamp, int_PercentComplete and int_MinutesWorked
I need to add two more fields to the query, but I do not know how to tell the SQL statement how to retrieve the data for the specfic record and inbed the fields into the Dataset being returned from the database to the web page.1) The first field I need is the most current recorded Date field from the tbl_Notes table for the each of the records returned in the above SQL statement. Similar to: SELECT TOP (1) dat_TimeStamp FROM tbl_Notes WHERE(num_TicketNumber = xxxx) ORDER BY dat_TimeStamp DESC2) The other field I need to return with the Dataset is the sum of the int_MinutesWorked for each of the tickets being retrieved. Similar to: SELECT SUM(int_MinutesWorked) AS TotalMinutesFROM tbl_Notes WHERE (num_TicketNumber = 49)
Hi,
I have large table rrsn_security_t - more than half a million rows. I do a complete update on all the rows of the table using the following query.
UPDATE rrsn_security_t
set
cusip = b.fmr_cusip,
master_issuer_num = b.mstr_isr_cusip,
ticker = b.fmr_symb,
description = b.fmr_name,
prim_exchange_code = c.exchange_key,
shares_otstndng = d.amount,
iv_type = b.iv_typ,
active = case when b.deact_date is null then 'Y' else 'N' end
FROM rrsn_security_t a INNER JOIN
ref_security_t b ON
a.security_id = b.fmr_cusip LEFT OUTER JOIN
shares_outstanding_feed_t d ON
b.fmr_cusip = substring(d.fmr_cusip,1,9) AND
d.fmr_type = 'OUTS' LEFT OUTER JOIN
rrs_exchange_t c ON
b.dft_exch_cd = c.exchange_id
where b.fmr_cusip not in (select security_id from rrsn_scrty_ovrrd_in_effect_t)
This is a part of a daily batch load and a DTS package. The table has one clustered index and three non clustered indexes. Two of them are covering indexes. The update is on all the columns that have the non clustered indexes.
The problem is that when I run the update the transaction log runs to more than a GB of memory and alomost takes an hour to do so. Without the index it takes around 300 MB and 7 mins.
I am not confortable with the idea of dropping and recreating the index since it is not necessary in SQL Server 7.0, though it was the case in the previous versions of SQL Server.
Also the query plan with the indexes on shows that Table spool/Eager spool to optimize rewinds takes 50% of the query cost.
Could any one help me with how I should deal with this situation.
Thanks in advance

I am creating mateialized view but it is failing with error that it can't be schema bound.
The query I am working to create materialized view are having joins with different tables and function.
Is it possible to create Indexed views on user defined functions?
I have a excel file which has a column called "Code" and their values are A,B,C,D,E,F,G,H. I want to create a new column called "status" based on the values of "Code".
Code:
A
B
C
D
E
F
G
H
If A,C,E,G then "status" = "Active" else if B,D,F,H then "Status" = "Inactive". I like to do it using "Derived Column".
I have created a table from another table where I specified that one of the fields, an number field, is sorted in ascending order and have NOT specified that it is to be an indexed field and there are 10 million records, from 1 to 10,000,000 exactly.
Now, if I query that table, asking to return records 1-1,000 from that non indexed number field that I sorted in ascending order (where number field <= 1,000) , will it run as fast as if it were indexed?
In other words, does SQL know somehow that these records are sorted in ascending order and so will not do a full table scan, stopping at 1,000 to return my data set?
Or is there no way for SQL to know this and only specifying an indexed field allows SQL to know that its in some order and so it doesn't have to do the full scan?
I am trying to use an indexed view to allow for aggregations to be generated more quickly in my test data warehouse. The Fact Table I am creating the indexed view on is a partitioned clustered columnstore index.
I have created a view with the following code:
ALTER view dbo.FactView
with schemabinding
as
select local_date_key, meter_key, unit_key, read_type_key, sum(isnull(read_value,0)) as [s_read_value], sum(isnull(cost,0)) as [s_cost]
, sum(isnull(easy_target_value,0)) as [s_easy_target_value], sum(isnull(hard_target_value,0)) as [s_hard_target_value]
, sum(isnull(read_value,0)) as [a_read_value], sum(isnull(temperature,0)) as [a_temp], sum(isnull(co2,0)) as [s_co2]
, sum(isnull(easy_target_co2,0)) as [s_easy_target_co2]
, sum(isnull(hard_target_co2,0)) as [s_hard_target_co2], sum(isnull(temp1,0)) as [a_temp1], sum(isnull(temp2,0)) as [a_temp2]
, sum(isnull(volume,0)) as [s_volume], count_big(*) as [freq]
from dbo.FactConsumptionPart
group by local_date_key, read_type_key, meter_key, unit_key
I then created an index on the view as follows:
create unique clustered index IDX_FV on factview (local_date_key, read_type_key, meter_key, unit_key)
I then followed this up by running some large calculations that required use of the aggregation functionality on the main fact table, grouping by the clustered index columns and only returning averages and sums that are available in the view, but it still uses the underlying table to perform the aggregations, rather than the view I have created. Running an equivalent query on the view, then it takes 75% less time to query the indexed view directly, to using the fact table. I think the expected behaviour was that in SQL Server Enterprise or Developer edition (I am using developer edition), then the fact table should have used the indexed view. what I might be missing, for the query not to be using the indexed view?
I have a table in which a non-primary key column has a unique index on it.
If I am inserting a record into this table with a duplicate column value for the indexed column, then what will be the error number of the error in above scenario? OR How could I find this out?
I am having issues trying to write a query that would provide me the unique GUID numbers associated with a distinct PID if the unique GUID's > 1. Â To summarize, I need a query that just shows which PID's have more than one unique GUID. A PID could have multiple GUID's that are the same, I'm looking for the PID's that have multiple GUID's that are different/unique.Â
Table1
GUID PID
GUID1 PID1
GUID1 PID1
GUID1 PID1
GUID2 PID1
GUID3 PID2
GUID3 PID2
GUID3 PID2
The result of the query would only have PID1 because it has two unique GUID's. PID2 would not be listed has it has the same GUID3 in each row.
Result:
PID1Â
Full Text search must keep a list of key words or items somewhere.
How can I get access to this list to present to a user.
For example: show me all indexed words starting with letter a* and then ac*.
I'm trying to find this information without success.
I've plan to writing Stored Procedure ("SP"). This SP contains program that produce a result and this result will insert into already define summary table. This SP will running every 30 minutes.
What is the best solution? I should put this already define summary table in existing Database or i should create a new database and create the summary table into this new database. Can i using ReportServer Database to create this summary table?
I'm using SQL Server 2005.

Hi,
I have a column that is unique that I would like to make into an IDENTITIY column after I insert some data into it.
I tried
alter table <table_name>
alter column <col_name> int Identity (1,1)
but it fails.

I simply need the ability using SQL to add columns in an existing table before (or after) columns that already exist.
The MS SQL implementation of ALTER TABLE doesn't seem to provide the before or after placement criteria I require. How is this done in MS SQL using SQL or is there a stored procedure I can use?
Thanks.
Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column. This column is a key field to othertables, so I want to keep the row numbers that are allready inserted.From the Query Analyzer, how do I do this?Thanks in advance!Regards,Gunnar VøyenliEDB-konsulent asNORWAY
View 3 Replies View RelatedHello everyone, I am new to ERWIN and I need helps from the experts outthere.We are using ERWin 4.1.2771 and have reversed engineered some MS SQLServer 2000 databases.The problem we are having is that we have a FK on a column to a tablewhere the PK of the referencing table is on another column (such as anidentity column). We have a unique index on the column in the PK tableand SQL Server allows you to build a FK reference even though thecolumn is not defined as the PK.Does anyone know how to create this type of FK within Erwin?Thank You
View 2 Replies View RelatedHello All,
I was wondering if anybody can help me with the following question:
I'm working on the application where the Database, it's table (2) and several stored procedures are involved. The database is SQL Server 2000. It's also very old and involves a lot of operations, stored proc and so on. I just need to re-write a piece of the app which is using existing stored proc. Most of them are DELETE, INSERT and so on. I don't want to work with real stage DB and need to make a copy of the Database to my Dev box. So I tried:
* Right click, All Tasks, Export Data into the newly created database on my dev box.
That doesn't work, every time I try doing it, it fails somewhere in the middle of the process. I'm thinking it happens because of complexity of the database. I tried several options there already. Still nothing. I need the whole databse to be copied because I'm not sure which stored proc the app is using so I need them all, and tables too. Is there another way of doing this?
Thank you,
Tatyana
If I rebuild the clustered index using this option (Drop Existing) without specifying the Fill Factor, would it it retain the original Fill Factor?
Thank you
Hello,
I just upgraded our existing 6.5 installation with the new SQL server 7.0. I can't get any of the existing stored procedures which I imported from 6.5 into 7.0 to allow me to edit them. I do all of my design from Visual InterDev and the SQL Server 6.5 version would allow me to create and edit stored procedures. It would also allow me to create/design new tables.
With SQL Server 7.0 I do not have an option to edit or create any of these items. I have created a new login, assigned it a password, given it admin rights/roles and I am still unable to remotely create these items. What am I doing wrong?
Thanks for any assistance

I have three tables :
England_Summer_2001
England_Summer_2002
England_Summer_2003
The tables have the following columns :
Player, Position, [From], [To], Fee, Type, ID, League, Window
I want to create a new table, EnglandFinal with all the data from the three tables although I'm guessing it would not be a good idea to copy the primary keys (ID column) as they would clash.
I have played around with CREATE and INSERT into and UNION but I get various errors. I'm sure I've done this before!
This creates a table from a single table :
select * into Final
from England_Summer_2001
How can I create a new table with a new name which is an exact copy of an existing table with:
1) All rows
2) no rows, only the structure of the table.

How do I create a copy of an existing database using vb.net? I have not been able to find solutions to the problem using vb.net. Can someone please help me. Thanks

We are having problems when creating new subscriptions or when trying to edit existing subscriptions. When editing an existing subscription, the report manager displays "An Internal error occured" message and when I look in the log the error says
Only members of sysadmin role are allowed to update or delete jobs owned by a different login
When trying to create a new subscription the report manager displays "An internal error occured" and the log says
System.Data.SqlClient.SqlException: The schedule was not attached to the specified job. The schedule owner and the job owner must be the same or the operation must be performed by a sysadmin.
We are running sql reporting services 2005 sp1. The report server database server is on a different machine to the reporting server. The existing subscriptions were set up previously on another report server which was originally our dev server. These subscriptions are working just can't change them, or create new ones.
Any help is much appreciated.
