Hi,
Is there any way to retrieve index information for a database through a SQL query?
I usually query out tables structure, et al using INFORMATION_SCHEMA. Is there anything like that for indexes?
Thanks,
Paul
Hi,I am tasked with creating a site in two languages: English and Farsi (Persian), which is a right-to-left language.I am having problems with the Faris version when it comes to stroing and retrieving data. I can use Farsi fonts and type data into tables, but when I try to retrieve them they are displayed as ?????. I check the table and it says there were problems retriving data and asks to run the query again. When I click on "Execute SQL", the content of the fields that were in Farsi change to ?????.I am new to MS-SQL and would appreciate it if you could tell me how to set up non-English database.TIA.

But, I need to be able to select any data base on the server
and then drill down into the tables, columns, etc.
I looked at sys.databases but can't see how to relate that to the
sys.tables to extend my query.
Is there a way?
I've looked at the information_schema area and catalog views
but I don't see a solution yet.
Hi,
I want to get information about all the indexes in a database.
Can any one suggest me a query for this.
Thanks.
I want to be able to see when records have been added to a table. The issue is we have a DTS job scheduled to run every night. The developer who wrote it password protected it and doesn't work here anymore. I want to add a step to this series of DTS jobs and want to run it just prior to his job. Is there a way to see when the records are being added or when this job is being run? Thanks again, you guys are the best.

I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?
So I'm reading http://www.sql-server-performance.com/tips/clustered_indexes_p2.aspx and I come across this:
When selecting a column to base your clustered index on, try to avoid columns that are frequently updated. Every time that a column used for a clustered index is modified, all of the non-clustered indexes must also be updated, creating additional overhead. [6.5, 7.0, 2000, 2005] Updated 3-5-2004
Does this mean if I have say a table called Item with a clustered index on a column in it called itemaddeddate, and several non-clustered indexes associated with that table, that if a record gets modified and it's itemaddeddate value changes, that ALL my indexes on that table will get rebuilt? Or is it referring to the table structure changing?
If so does this "pseudocode" example also cause this to occur:
sqlstring="select * from item where itemid=12345"
rs.open sqlstring, etc, etc, etc
rs.Fields("ItemName")="My New Item Name"
rs.Fields("ItemPrice")=1.00
rs.Update
Note I didn't explicitly change the value of rs.fields("ItemAddedDate")...does rs.Fields("ItemAddedDate")=rs.Fields("ItemAddedDate") occur implicitly, which would force the rebuild of all the non-clustered indexes?
I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.
create table #fragmentation
(
FragIndexId BigInt Identity(1,1),
--IDENTITY(int, 1, 1) AS FragIndexId,
DBNAME nvarchar(4000),
TableName nvarchar(4000),
[Code] ....
What is the difference please?
View 1 Replies View RelatedHow can I efficiently retrieve the top x managers within the top y regions within the top z states within the top q countries?
The only way I have been able to do this is to first find the top q countries, and store the list in an IN clause. Then for each of those, find the top z states and create another IN clause that contains the country+state concatenated. Then for each of those, find the top y regions and concatenate country+state+region. Then finally find the top x managers within this IN clause.
This works fine for a few hundred records, but once it reaches the thousands, it takes much too long. The final IN clause contains thousands of entries.
Isn't there a simpler way to approach this, especially with SQL Server 2005?
i am using a stored procedure, lets say spTemp, that calls sp_executesql within it. in the sp_executesql procedure i am passing parameters from the stored procedure 'spTemp'. i want to retrieve the result of the sp_executesql statement so as to perform further calculations in spTemp. is there a way of doing this?
ex:
create procedure spTemp
(
@abc int
)
as
declare @temp int
exec sp_executesql 'select @temp = Id from Product where @abc > 10'
...
how to get the value @temp from this statement?
Hi all,
I've inherited the administration of two SQL Servers one 7.0 and the other 2000. We are looking into upgrading to 2005 so I'm gathering all the info I can on the DBs and applications using them.
Now, how can I check if a DB is currently in use? Is there a way to find out when a DB was last accessed?
By the way, I've never done DB administration so you can figure out how desperate I'm getting.
Thanks all for your help,
GS

Hi, I hope someone can help me with this.
I want to get a query from a database
from between '3' AND '5' (NO PROBLEM)
but I want to add that I want info from 7 and up
how would I write that ? (if I do it in seperate lines the query returns nothing) which is not true.
Thank you.
Well i need to document what tables i have in my stored procedures. Im really new to sql as well. And the problem is if i try code i have or sp_depends for instance it will only tell me the tables that are in that DB so if I have multiple tables from different DB's they are left out. I was told that sp_MSForEachDb for go through each DB and I could try it that way. Any help or example code dumbed down for me would be awesome. This was posted in a previous thread but i though this would be a better explanation

Hi
I've got a module that contains the following function.
Imports System.Data.SqlClient
Module SQL_Sprocs
Function ListUsers()
Dim conn As New SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("DBConn"))
Dim cmd As SqlCommand = New SqlCommand("list_users", conn)
cmd.CommandType = CommandType.StoredProcedure
conn.Open()
Dim dr As SqlDataReader
dr = cmd.ExecuteReader
ListUsers = dr
dr.Close()
conn.Close()
End Function
End Module
I then want to call this function from my webform. So I'm using the following
Dim dr As SqlClient.SqlDataReader
dr = Timetracker.SQLProcs.ListUsers()
Do While dr.Read
Label1.Text &= dr("first_name") & " " & dr("last_name") & ", "
Loop
dr.Close()
But it's not working. I want to have a module that contains all my sprocs and be able to call them from the individual webpages.
What am I doing wrong?

I have records in a table and 1 column is in the smalldatetime format which stores the date in the format "2004-09-22",2004-09-20",2004-09-12",2004-08-04" etc etc.
Can anyone tell me how to craft an SQL statement so that i can retrieve records for a certain month.For example,if i want to retrieve records for the month of September,i would get "2004-09-22",2004-09-20",2004-09-12" in results.

"I meant to delete just one assignment, doing which was giving me difficulty.
I deleted a whole category by accident which had most of my daily grades in it for a course with quite a few of them. I was negligent in backing them up, so I cannot restore them. I have an XLS file from the midterm, but am missing about 6 grades after that.
Is there any way to recover the grades I had in the deleted category. It has been a couple of days since I entered any new grades. HELP!"
My current backup strategy is to do a full backup 5 pm, differentials every 2 hours, logs every 30 min, all so they arenot simultaneous. Backing these all to same backup device via three different jobs.
Then the server is backed up to tape shortly after the 5 pm full backup.
Obviously, I can't restore from the backup for this situation because it would hurt other data.
But - is there a way I can take last night's backup from tape and restore it to a different database than our production database? (Such a database doesn't at this time exist. Would I detach, copy over the files, and then reattach on prod and attach on the devl side, and then restore from the backup device to the devl copy?)
I've never had to perform this kind of rescue and am wondering if my backup strategy is flawed since it isn't immediately evident how I can easily do this.
I needed a similar thing from our Oracle DBA yesterday, and he went to tape, copied out a table and put it on the Oracle database under a different owner, and I easily fixed the few records that I had botched.
That's exactly what I need to do now with MS SQL 2000.
As the faculty dude said, "HELP!"
And Thanks.
Hi,
I was hoping someone would be able to help me, I trying to go through several databases, 111 to be exact, and get the data out of a particular table which is present in all the databases on the same server.
I know how to get the names of the databases from the INFORMATION_SCHEMA, but how can use the name for it to cycle through all the databases and get data out of the one particular table.
Hi,
I have a giant SQL query that retrieves a bunch of information from a couple of tables for use on a page, and I would like some help on constructing the SQL to get exactly what I have in mind. I have a table - called scContacts - that contains a list of contacts with detailed information. The contacts in the table are regular sales contacts, sales reps, and sales managers. Another table - called scCompany - contains a list of companies with detailed information.
For each company, we have a certain sales manager (or user) pertaining to that company as well as potentially a certain rep. The problem is that the contact tied to the company, the sales manager tied to the company, and the rep tied to the company all come from the same table. Here is the base SQL code I've used to get everything but the sales rep's name and sales manager's name:
----- SQL CODE -----
SELECT DISTINCT
scContacts.ID,
scContacts.inheritCoAddr,
scContacts.fName,
scContacts.lName,
scContacts.contact,
scContacts.billToAddress1,
scContacts.billToAddress2,
scContacts.billToState,
scContacts.billToZip,
scContacts.billToCity,
scContacts.billToCounty,
scContacts.billToCountry,
scCompany.ID AS companyID,
scCompany.companyName,
scCompany.companyURL,
scCompany.billToAddress1 AS companyAddress1,
scCompany.billToAddress2 AS companyAddress2,
scCompany.billToCity AS companyCity,
scCompany.billToState AS companyState,
scCompany.billToZip AS companyZip,
scCompany.billToCounty AS companyCounty,
scCompany.billToCountry AS companyCountry,
scCompany.businessType,
scCompany.phoneExt,
scCompany.phoneNum,
scCompany.faxNum,
scCompany.minEmployees,
scCompany.maxEmployees,
scCompany.actionTypeMAX,
scCompany.actionDateMAX,
scCompany.actionTimeMAX,
scCompany.statusID,
scCompany.userID,
scCompany.repID
FROM
scCompany,
scContacts
INNER JOIN
scStatus ON
scStatus.ID = scCompany.statusID
WHERE
scgroupContacts.contactID = [insert cookie value]
AND
scgroups.ID = [insert cookie value]
AND
scCompany.ID = scContacts.companyID
AND
scCompany.groupID = scgroups.ID
----- END SQL CODE -----
As indicated right now, this SQL code will retrieve all of the contact and company information for a certain contact ID which comes from a cookie value (inserted in ASP). I want to get the [fName] and [lName] fields from scContacts table where the scContacts.ID = scCompany.userID, and I also want those same fields from scContacts table again where the scContacts.ID = scCompany.repID. It would be simplest and most efficient if I could do this all at once (and I'm sure it's possible). How would I change the SQL to bring in that information from the same table two more times, tying their ID's to ID's in the company table?
thanks,

i lost a table with lots of data - there's around 10,000 records inserted daily.
my problem was i only realized this morning (and i lost it last night) and i have the backups backing up each day every hour - so the backup had already overwritten it seems the db that was missing the table)
my backup type is set to append - so i though i could retrieve by date time but it only let me retrieve the backup at 11pm(tune if last backup) and no earlier time. is there anyway of getting the data from the 7 pm backup -- again it backsup each hour to the same file - set to append so i thought that meant i could choose a time but it doesn't seem to be working.
please advise.

Up to the moment I've got enough knowledge for read data stored into .LDF files by dbcc log and so on. It's very useful and interesting. Now, I wonder how to retrieve the same information but on MDF files.
At first, I want to make sure that is not possible by mean of traditional methods (dbcc or something like that) I suppose so but I'd like to hear opinions regarding that.
