I am trying to create a table that holds info about a user; with the usual columns for firstName, lastName, etc.... no problem creating the table or it's columns, but how can I "restrict" the values of my State column in the 'users' table so that it only accepts values from the 'states' table?
View 2 RepliesI am trying to create a clustered index on a View of a table that has an xml datatype. This indexing ran for two days and still did not complete. I tried to leave it running while continuing to use the database, but the SELECT statements where executing too slowly and the DML statements where Timing out. I there a way to control the server/cpu resources used by an indexing process. How can I determine the completion percentage or the indexing process. How can I make indexing the view with the xml data type take less time?

Can anyone help me on this...
when i select data from table using select statement it takes huge amount of time....The table contains 7 million entries and when i select by mentioning a criteria it takes around 45 secs..The system has 4GB RAM and Dual Processing CPU. The select statement does not contain any grouping and all..
Will it take this much time to retrieve data.?.
The table does include an indexed field,
So can anyone help me on the different things i can do to make the retrieval faster?

Hi all, I am not over familiar with SQL, I am a VB programmer, simply I need to achieve the following within Enterprise Manager.
I have 2 tables, different designs, different number of rows, I simply need to check whether the contents of a column in the first table is in a column in the second table, just simply a table/column to table/column data check for the same data content.
Easy Peasy for you guys, any help would be appreciated.
I have created new columns fields in a table using EManager. However, I am wondering Which command do we use to create columns through the analyser??? Is it the same like the "Insert into"?
View 3 Replies View RelatedHello,
I'm just using SSIS to build my first data warehouse. I've read quite a bit, but I'm stuck at the very first task: I need to assign a key column (just an int that starts at 1 and basically numbers the rows). What transformation do I use? I was going to use the derived column, but if that's the case, I don't know the script for the expression to do it. If I'm right, would someone mind supplying that also?
Thanks a lot,

Hi,Good morning to All.
I have some doubt.I cannot do anything without knowing the reason why we are doing that particular thing.
Any way, my doubt is:
While creating table, in some places I see COLLATE clause.
For example, recently I have seen this.
CREATE TABLE dbo.OrderDetails( OrderDetailID INT IDENTITY(1,1) NOT NULL, ItemNumber VARCHAR(20) COLLATE SQL_Latin1_General_CP1_CI_As NULL, Qty INT NULL)ON [PRIMARY]
In the above table, why the Collate clause for ItemNumber column? What is the advantage with that clause?I have seen sql server help for this. I have found 1011 results for the query SELECT * FROM fn_helpcollations().Then I searched for SQL_Latin related collations using: SELECT * FROM fn_helpcollations() where name like 'SQL_Latin%'I have found 31 results.How can I know which clause i have to use for which type of query?
Can anybody please tell answers for all these doubts?
Thanks in advance.
Regards,Ashok kumar.
If on the source I have a new column, the script generated by SqlPackage.exe recreates the table on the background with moving the data into a temp storage. If the table is big, such approach can cause issues.
Example of the script is below: in the source project I added columns [MyColumn_LINE_1] and [MyColumn_LINE_5].
Is there any way I can make it generating an alter statement instead?
BEGIN TRANSACTION;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
SET XACT_ABORT ON;
CREATE TABLE [dbo].[tmp_ms_xx_MyTable] (
[MyColumn_TYPE_CODE] CHAR (3) NOT NULL,
[Code] ....
The same script is generated regardless the table having data or not, having a clustered or nonclustered PK.
I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?
I have think three ways to do it.
1. leave as it is.
2. 7 years partition on one server
3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)
Does column order matter when creating a table? For example, Should NOT NULL columns always come before NULL columns? Should most frequently used columns always be near the top? What about text, ntext and image data types? Should they always appear near the end of the column order?

hello all,
I don't know how to update table A with data from table B without specifying every column.
These two tables have the same fields and same structure.
I know that it's possible to do the following:
update table A
set A.name = B.name,
A.job = B.job
from table B
But I have many columns and don't want to describe every column, is that possible?
Thanks!
I have a form with a drop down box so the user can select a quote.. When a quote is selected i need to populate a table of all the records associated with the quote id. I need the table to be created in such a way that the user can add new rows, delete rows and edit the data. Then all of the changes need to be written back to the database. Whats the most efficient/best way of doing this and if you have any ideas can you explain them as thoroughly as possible! I'm currently upgrading an access database to a sql server back end with an asp.net client and it's taking me a while to get to grips with all the changes!Thanks in advance,Chris

If I want to create an SQL data table on the server, I go to Server

It would suit me, for a current job, to be able to create the table itself programatically.
I don't know how to do this. Can it be done ? If so, could someone give
me a starter, please ? Four cols with a key in the first.

hi, i'm trying to create a table and populate it with data from another database residing on the same server. i've done this on oracle using tables within the same database and am just making a first effort with the added twist of a different database. this is what i've been doing so far...
CREATE TABLE facility_dimension
(
fac_id INT IDENTITY(1,1),
tri_fac_id CHAR(17),
fac_nameVARCHAR(100),
street VARCHAR(100),
city VARCHAR(100),
county VARCHAR(50),
state VARCHAR(4),
longitude REAL,
latitude REAL,
PRIMARY KEY(fac_id)
)
SELECT tri_facility_id, facility_name, street_address,
city_name, county_name, state_abbr, fac_latitude,
fac_longitude
FROM TRI_2004.form_1;
....where TRI_2004 is the other database and form_1 is the table. the result is creation of the new table and then the output of the secondary query. i'm assuming this can even be done but if it can't that would be helpful to know as well. thanks in advance!

Hi,
The scenario is the data comes from various sources and its staged into staging database. From this staging database it goes into data warehouse database. Everyday this staging database is truncated and repopulated from various sources.
I've a dimension table called DimCustomers which consists of around 300,000 rows and has lots of different types of SCD columns. It takes around 4-5 hours to load data from staging to this dimension table. Currently I'm using a For Loop container which uses a store proc to extract 15000 rows each time and populate my dimension tables. First couple of loops it goes off quickly but as and when the number reaches half of the count it slows down and hence it takes around 4-5 hours to load data.
What would be the best approach to populate this kind of dimension table.
Thanks

For example,I have a table "authors" with a column "author_name",and it has three value "Anne Ringer,Ann Dull,Johnson White".Here I want to create a new table by using a select sentence,its columns come from the values of the column "author_name".
can you tell me how can I complete this with the SQL?
We have a proc that adds some fields to a few tables of ours and normally there are no issues. For one of our client databases this process is taking anywhere from 5-10 minutes to add the fields. This causes an issue where the app will timeout waiting. After plugging around and looking at the proc and trying different items i found it to only be for this one database and ONLY when there is data in the table. If i truncate the table and run the same procedure everything is fine. Tables all have same index on 4 columns and the columns being added are not indexed because of the stupid hoops we have to jump thru to pre-pivot data for our reporting package.

View 1 Replies View RelatedI have a row that is being used log track plays on our website.
Here's the table:
CREATE TABLE [dbo].[Music_BandTrackPlays](
[ListenDate] [datetime] NOT NULL DEFAULT (getdate()),
[TrackId] [int] NOT NULL,
[IPAddress] [varchar](20)
) ON [PRIMARY]
There's a CLUSTERED INDEX on ListenDate ASC and a NON CLUSTERED INDEX on the TrackId.
I have a TRIGGER on the Music_BandTrackPlays table that looks like the following:
CREATE TRIGGER [trig_Increment_Music_BandTrackPlays_PlayCount]
ON [dbo].[Music_BandTrackPlays] AFTER INSERT
AS
UPDATE
Music_BandTracks
SET
Music_BandTracks.PlayCount = Music_BandTracks.PlayCount + TP.PlayCount
FROM
(SELECT TrackId, COUNT(*) AS PlayCount
FROM inserted
GROUP BY TrackId) AS TP
WHERE
Music_BandTracks.TrackId = TP.TrackId
When a simple INSERT statement is done on the Music_BandTrackPlays table, it can take quite a long time. When I remove the TRIGGER the INSERTs are immediate. The Execution plan for the TRIGGER shows that a 'Inserted Scan' is taking up most of the resources.
How exactly is the pseudo 'inserted' table formed?
For now, I think the easiest thing to do is update my logging page so it performs 2 queries. One to UPDATE the Music_BandTracks table and increment the counter, and perform the INSERT into the Music_BandTrackPlays table seperately.
I'm ok with that solution but I would really like to understand why the TRIGGER is taking so long. The 'inserted' pseudo table will be 1 row 99% of the time. Does SQL Server perform a table scan on all 20 million rows in order to determine what's new and put it in the inserted pseudo table?
Thanks!
