Requirement:
I wanted to create another table based on the column values. For eg: I have to take the employee id and check for what value he has under owns column in the table. I take only 3 values and then these values should go to the newly created columns (owns1, owns2,owns3).
if there is no value for any of these columns it should have null values loaded in them.
The result of the modification should look like this:->
Note: eventhough employeeid 3 owns more than 3 things we only take 3 of what he owns and populate to above coloumns.
In addition to it, the column OWNS will have more than 500 different values in them.
Its kind of urgent and if anyone knows how to , Can you please help me on this.
Thanks a lot.

I have a pivot table query I am running and wanted to find out if there was a way to pull in the dates like getdate() - 12 months, getdate() - 11 months, etc. instead of hard coding the dates.
Here is my query
SELECT Client, [4/1/2007 12:00:00 AM] AS Month1, [5/1/2007 12:00:00 AM] AS Month2, [6/1/2007 12:00:00 AM] AS Month3, [7/1/2007 12:00:00 AM] AS Month4, [8/1/2007 12:00:00 AM] AS Month5, [9/1/2007 12:00:00 AM] AS Month6, [10/1/2007 12:00:00 AM] AS Month7, [11/1/2007 12:00:00 AM] AS Month8, [12/1/2007 12:00:00 AM] AS Month9, [1/1/2008 12:00:00 AM] AS Month10, [2/1/2008 12:00:00 AM] AS Month11, [3/1/2008 12:00:00 AM] AS Month12, [4/1/2008 12:00:00 AM] AS Month13, Engineer FROM (SELECT Client, DollarsBilled, SlipDates, Engineer FROM dbo.MonthlyClientBillables) p PIVOT (SUM(DollarsBilled) FOR SlipDates IN ([4/1/2007 12:00:00 AM], [5/1/2007 12:00:00 AM], [6/1/2007 12:00:00 AM], [7/1/2007 12:00:00 AM], [8/1/2007 12:00:00 AM], [9/1/2007 12:00:00 AM], [10/1/2007 12:00:00 AM], [11/1/2007 12:00:00 AM], [12/1/2007 12:00:00 AM], [1/1/2008 12:00:00 AM], [2/1/2008 12:00:00 AM], [3/1/2008 12:00:00 AM], [4/1/2008 12:00:00 AM])) AS pvt
I'm building a system that imports data from several source, Excel files, text files, Access databases, etc. using DTS. The entire process revolved around MS SQL Server, by the way.
I figured I would create denormalized tables that mirror the Excel and flat files, for example, in structure, import data to those, clean up and remove duplicates there, then break those out into my normalized table structure later.
Now I've finished the importing part (though this is going to happen once a week) and I'm onto breaking up the denormalized tables.
I'm hesitating because I'm not sure I've made the best decisions in terms of process, etc.
I've decided to use cursors to loop over the denormalized tables and use batch insert statements to push data out to the appropriate tables.
Any comments? Suggestions? All is welcome.
I'm specifically interested in hearing back on the way I've set up the intermediate, denormalized tables and how I'm breaking them up using cursors (step 2 of the process below). Still, all comments are welcome. As are suggestions for further reading.
Thanks again...
simplified example (my denormalized tables are 20 - 30 colums wide)
denormalized table: =================== name, address, city, state, cellphone, homephone
I'm breaking up the denormalized tables like this (*UNTESTED*): =================================================
DECLARE @vars.... (one for each column in my normalized table structure, matching size and type)
DECLARE myCursor CURSOR FAST_FORWARD FOR SELECT name, address, city, state, cellphone, homephone FROM _DNT_myWideTable INTO
WHILE @@Fetch_Status = 0 BEGIN -- grab the next row from the wide table FETCH NEXT FROM myCursor INTO @name, @address, @city, @state, @cellphone, @homephone
-- create the person first and get the ID with @@IDENTITY INSERT INTO tblPerson (name) VALUES (@name)
SET @personID = @@IDENTITY
-- use that ID to coordinate inserts across other tables INSERT INTO tblAddress (FK_person, address, city, state, addressType) VALUES(@person, @address, @city, @state, 'HOME')
INSERT INTO tblContact (FK_person, data, contactType) VALUES(@person, @cellphone, 'CELLPHONE')
INSERT INTO tblContact (FK_person, data, contactType) VALUES(@person, @homephone, 'HOMEPHONE')
When rendered, the pages with the small tables on have a lot of white blank space at the right of the table. This is probably caused by the big table on page 3.
This report is distributed by email in Excell format. So on sheet 1 and 2 there are a lot of white cells on the right of the tables. When trying to print, they just want to use the "landscape" option and the "fit to page" option. Because of the empty white cells, the fit to page option reduces the first 2 tables to a very small table which covers only 50 % of the page width. The other 50 % is reserved for the empty cells.
Off course, I know that deleting the empty cells offers a solutions, but it would be a lot more handier if there were no empty cells in the first place.
we can easily load a file into db tables. However, my main concern here is the number of columns in the file. A text file TEXT_1400.txt has 1400 columns. I am unable to load data to my db table using BCP or BULK INSERT commands, as maximum of 1024 columns are allowed per table in SQL Server 2008.
We can still go ahead and create ‘Wide Table’ (a special table that holds up to 30,000 columns. The maximum size of a wide table row is 8,019 bytes.). But when operating on wide table, BCP/BULK INSERT commands still fail. After few hours of scratching my head over BCP and BULK INSERT, I observed that while inserting BCP/BULK INSERT commands are unable to identify SPARSE columns and skip these columns, which disturbs column mapping and results in data conversion and trancation errors.
Is there any proper way to load this kind of files into the db table?
I have a datagrid in my file along with an Update Query.
My Update Query basically adds the numerical values in two columns together when the page is loaded. This means whenever the page is Refreshed the Update query is fired.
This is my Update Query (which is in an Stored Procedure):
UPDATE Rental SET TotalFee = ExtraFee + TotalFee WHERE DaysOverdue >= 0
I have declared my query in the 'Page_Load' part of the coding, because I want the query to run automatically. Not manually by a button.
My main question is that how can I get the query to run only once a day, no matter how many times the page is loaded.
SELECT ChannelCatID as '@type', ChannelID as 'Channel/@id', ChannelName as 'Channel/Name', RSSFeedURL as 'Channel/URL' FROM ChannelMaster FOR XML PATH('Item'), ROOT('DOC')

I have a table with about 20,000 records. So, to minimise performance issues, i try to only retrieve the top 100 records. The databaset retrieved can be paged and sorted.

hi. i'm trying to make a report in asp that sums up a whole bunch of statistics. the report is quite lengthy and takes about 2 minutes to load. i thought i would solve that problem by making a table to dump the statistics into instead of calculating the statistics every time the report is viewed. this way, the page would just read the table with the statistics already put in it. these statistics would be updated every day or two so i don't need anything up to the minute.however, i have run into a small problem which is actually updating the information in the table. my new table is called OfficeReport and it looks like this:UserID Stat1 Stat2 Stat3 ...... Stat3223 0 0 0 056 0 0 0 072 0 0 0 0this is a query for one of the statistics i am currently using:SELECT DefendantCase.UserID, COUNT(DefendantCase.UserID) AS CountOfUserID FROM DefendantCase LEFT JOIN UserDescription ON DefendantCase.UserID=UserDescription.UserID WHERE UserDescription.Status=1 AND UserDescription.UserType=1GROUP BY DefendantCase.UserIDif i run this query, this is what i get:UserID CountOfUserID54 2160 1052 294 427 22how can i modify this query so its output updates the same UserID column in the OfficeReport table? Thanks!
I need to make a backup of a table so that if I mess it up I can put the data back to where I started...
I am going to insert some new rows and update values in some existing rows. So before I do this and find out I messed it up...how do I make a copy of Table A as Table B?
I would actually like to make a copy to table B, then run my changes into B, make sure all is correct, and then transfer the revised data from B over to table A replacing its data. What approach would be best here to accomplish this?
I am using a local variable to capture datetime and then select records from another table by making use of the above local variable result. But the query is running too slow when I use the local variable
declare @a smalldatetime select @a=last_run_time from job_status where job_des='sample'
SELECT * FROM History WHERE CHANGE_DATE> @a
Instead of the above select statement if I use the below statement it is returning results quickly. Can someone help me in tuning the above query. SELECT * FROM History WHERE CHANGE_DATE> '5/23/2008 6:22:00.000 AM '
History table has columns ( case number, change_date, change_desc). I have two indexes defined on the above table one is on case_number and the other on change_date.I tried using force index but still the query is running slow.
SET @propname = NULL -- can be Null or have wild card values
SELECT col1, col2, col3, propertyname FROM testtable where col1 = 1 and col2 = 2 and col3 = 3 and (@propname IS NULL OR propertyname LIKE @propname)
col1, col2, col3 are part of a clustered index
propertyname is a nonclustered index
This is the predicament. If the "@propname is NULL" is first in the OR statement then the query will use the clustered index for finding the record. If I put "@propname is NULL" last then it uses the propertyname index no matter what. So I either get full index scans if NULL is ever used on property names or I get consistent two second long searches on the clustered index. Any way to have the best of both worlds? Or do I have to divide up my query into more stored procedures?
I have a huge question, it's for my job im doing now. I have a table with the name TWO.dbo.SVC06105. I want to be able to take the word "TWO" and put that into a variable. I know this doesn't look correct, but I want to be able to do something like this:
DECLARE @GPNAME CHAR(100) SET @GPNAME = 'TWO'
SELECT * FROM @GPNAME.dbo.SVC06105
I know the SELECT statement isn't correct, but I hope that you guys understand what i'm trying to do through this example. BTW, I am new to this team so nice to meet you all. L8er
I want to make a sqldatasource to insert data ito a table with values from textfields page. I want to use the sqldatasource programically (not bind it to a formcontrol). I drag a sqldatasource from the toolbox to the design surface and start configuring the datasource. I spesify a custom sql statement, select the "Insert" tab and insert the table I want to store into the builder. Then I select the fields and the values (parameters from tue textfields. I test it with the "Execute query" button and the results is stored in the table. (everything seems ok) I press the "OK" button but both the "Next" and "Finish" buttons are dissabled, o I can not store the query. What is going wrong. Can someone please help me ? Tom Knardahl
Hello, Im a very new to SQL server etc, so please bear with me.
I am currently trying to find a quick way of making a large number of database entries within a particular table all have the same value in one particular column.
I have created a query in MS SQL Server Management Studio, which outputs all the entries in a particular table that I want to change. Currently they all have different values in a certain column in this table, and I want them all to have the same value in that column.
I.E. I WANT two columns C1# and C2#, where C1# contains data from 2015 and C2# contains data from previous year (2014). If 2015 data is not present, then C1# will contain data of 2014 and C2# will contain data of 2013.
I've seem some good posts similair to this, but I haven't been able to find my exact issue.
I have the following table:
ID Name Location Start End
1 Joe NY 2000 2001
1 Joe CA 2002 2004
1 Joe MA 2005 2008
2 Sue NJ 2003 2004
2 Sue FL 2004 2008
3 Bob CA 1999 2000
3 Bob WA 2001 2004
3 Bob OR 2005 2006
3 Bob MI 2007 2008
As you can see, the Location, Start and End dates can vary for each person and I don't know how many rows a single person might have.
The result I want, is a "pivot like" table.
ID Name Location1 Start1 End1 Location2 Start2 End2 Location3 Start3 End3 Location4 Start4 End4
1 Joe NY 2000 2001 CA 2002 2004 MA 2005 2008
2 Sue NJ 2003 2004 FL 2004 2008
3 Bob CA 1999 2000 WA 2001 2004 OR 2005 2006 MI 2007 2008
I assume I can first do a count of the maximum rows for an individual and that is greatest number of columns I would need. But doing that and trying to figure out the rest has really stumped me.
Any thoughts, ideas and suggestions would be greatly appreciated.
I have a table that is fairly large, and I need to make a change to one of the columns in the table. Namely I need to change the datatype and rename that column. When I try to save the updated table, I keep getting a timeout error that says.
'eligibility (dbo)' table - Unable to create index 'PK_eligibility'. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Any ideas on how to make the table change more efficient or change the timeout period. I need to keep the existing data in the table. I am using sql server managment studio(2005) connected to a sql server 2000 database.
Is a table 45 columns wide too wide? Most of the data is very small( check boxes, one word fields etc.) I have one giant form that needs to be filled out and uploaded to the database. I don't want to fragment the table too much because it will be a pain to update it. This table will have to be searched, that's why I am concerned with the width. I am hoping that an index would help out and would provide enough performance that I can keep a wide table.
ok, i have been charged with the task of searching a server that houses 50-60 client databases. all databases are identical, created from a prototype. i have discovered an issue whereby one of the clients db is missing a required sproc. they now want me to check all db's to see if anyone else is missing the sproc or not. i have a UN and PASS to login to the server that houses all db's. is there a method for me to query all db's at once and check for the sproc? or will i have to go through them all manually (which could become quite time consuming as there are so many db's, and quite a large number of sprocs in each. the sprocs seem to be listed in a semi-random order in each db as well) thanks all
Is there any way to create Server wide UDFs? We have alot functions that are spread across multiple databases and its time consuming going around databases looking for them. What would be nice is to create functions at the server level which can be accessed within any database, like the GETDate() function.
I'm working on a system that is very address-centric and detection ofduplicate addresses is very important. As a result we have brokenaddresses down into many parts (DDL below, but I've left out somereference tables for conciseness), these being state, locality, street,street number, and address. The breakdown is roughly consistent withAustralian addressing standards, we're working on finalising this.Because we carry the primary key down each of the levels, this hasresulted in our address table having a very wide primary key (around170 characters). We refer to addresses from a number of other tablesand although my instinct is to use this natural key in the other tablesI wonder if we should just put a unique index on the natural key,create a surrogate primary key and use it in the other table. Anythoughts?CREATE TABLE dbo.States (StateID varchar (3) NOT NULL ,StateName varchar (50) NOT NULL ,CONSTRAINT PK_AddressStates PRIMARY KEY NONCLUSTERED(StateID))CREATE TABLE dbo.Localities (Locality varchar (46) NOT NULL ,StateID varchar (3) NOT NULL ,Postcode char (4) NOT NULL ,CONSTRAINT PK_Localities PRIMARY KEY NONCLUSTERED(Locality,StateID,Postcode),CONSTRAINT FK_AddressLocalities_AddressStates FOREIGN KEY(StateID) REFERENCES dbo.States (StateID))CREATE TABLE dbo.Streets (StreetName varchar (35) NOT NULL ,StreetTypeID varchar (10) NOT NULL ,StreetDirectionID varchar (2) NOT NULL ,Locality varchar (46) NOT NULL ,StateID varchar (3) NOT NULL ,Postcode char (4) NOT NULL ,CONSTRAINT PK_Streets PRIMARY KEY CLUSTERED(StreetName,StreetTypeID,StreetDirectionID,Locality,StateID,Postcode),CONSTRAINT FK_Streets_Localities FOREIGN KEY(Postcode,Locality,StateID) REFERENCES dbo.Localities (Postcode,Locality,StateID))CREATE TABLE dbo.StreetNumbers (StreetName varchar (35) NOT NULL ,StreetTypeID varchar (10) NOT NULL ,StreetDirectionID varchar (2) NOT NULL ,Locality varchar (46) NOT NULL ,StateID varchar (3) NOT NULL ,Postcode char (4) NOT NULL ,StreetNumber varchar (15) NOT NULL ,BuildingName varchar (100) NOT NULL ,CONSTRAINT PK_StreetNumbers PRIMARY KEY CLUSTERED(StreetName,StreetTypeID,StreetDirectionID,Locality,StateID,Postcode,StreetNumber),CONSTRAINT FK_StreetNumbers_Streets FOREIGN KEY(StreetName,StreetTypeID,StreetDirectionID,Locality,StateID,Postcode) REFERENCES dbo.Streets (StreetName,StreetTypeID,StreetDirectionID,Locality,StateID,Postcode))CREATE TABLE dbo.Addresses (StreetName varchar (35) NOT NULL ,StreetTypeID varchar (10) NOT NULL ,StreetDirectionID varchar (2) NOT NULL ,Locality varchar (46) NOT NULL ,StateID varchar (3) NOT NULL ,Postcode char (4) NOT NULL ,StreetNumber varchar (15) NOT NULL ,AddressTypeID varchar (6) NOT NULL ,AddressName varchar (20) NOT NULL ,CONSTRAINT PK_StreetNumberPrefixes PRIMARY KEY CLUSTERED(StreetName,StreetTypeID,StreetDirectionID,Locality,StateID,Postcode,StreetNumber,AddressTypeID,AddressName),CONSTRAINT FK_Addresses_StreetNumbers FOREIGN KEY(StreetName,StreetTypeID,StreetDirectionID,Locality,StateID,Postcode,StreetNumber) REFERENCES dbo.StreetNumbers (StreetName,StreetTypeID,StreetDirectionID,Locality,StateID,Postcode,StreetNumber))
Dear All, what are different types of joins avialable with sql server6.0, 7.0, 2000 and 2005 and now 2008...
the reason behind the question is :
i've used the swiss Sql tool to boost the performance of my join queries. and the tool has given some best options. those are working fine with database but failing at application level.
i found the reason is because of Loop join, Hash Join, Merge join.
your valubel suggsions are needed.
thank you veru much

Can we create custom object wide roles? In the same manner that db_datareader in effect grants SELECT on all tables, can we create roles that affect all objects without having to explicitly grant the permission on every object?
Hi, I have an ASP.NET application that uses VARCHAR extensively in the tables and, more importantly, stored procedures (a couple hundred of them).
This app needs to start accepting foreign language in some areas, so I was wondering if there was some way to go through the tables and, more importantly, the stored procedures and change all "VARCHAR" references to "NVARCHAR" ?
Are the stored procedures stored as a text file somewhere on the server? If so I could use some sort of "replace" software utility to go through and change all VARCHAR to NVARCHAR
I have a wide fact table that I'm feeding to an SSAS cube. I was advised that splitting the measure group into two will improve performance when querying the cube.
I cannot find any documentation that supports this, in fact I get a blue curved line suggesting that I merge the measure groups since they have the same dimensionality and granularity.
I guess the best practice is what the blue line states, but without knowing the internals of SSAS I can undestand that a smaller measure group may be easier to handle, or create more specific aggregations for.
