hello sir
Thank for ur response to me in such a way.
I m student of cs in final semester & designing a project for online test series for all subject like mathematics, physics, chemistry, geography. Ihave a pb for storing mathematical questions which includes special symbols in organic chemistry structural farmulas etc.How can we store in database. i m sending a test paper for better understanding. plz help me.I will be hioghly obliged to u for this.
I would like to is there any way we can store mathematical equations, that can be typed using equations 3.0, in sql server database as a column. What would be the datatype for the same.
I am pulling my hair out having built my first application using WWF, I have moved the application off the development machine to a machine ready for production for the persistence store will now be on a remote server.
I cannot create a connection string for the persistence store that will allow me to attach to the mdb on the remote server.
the original connection string in development was:
Data Source=.SQLEXPRESS;AttachDbFilename='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataWorkflowPersistenceStore.mdf';Integrated Security=True;Connect Timeout=30;User Instance=False
I cannot create an equivalent string that does not return a error like this one:
An attempt to attach an auto-named database for file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataWorkflowPersistenceStore.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
I did simply copy the WorkFlowPersistenceStore.mdf from the development machine to the server machine (completely independant environments) - It has worked in the past for other non wwf databases - Is there something particular about the wwf database that would have prevented this?
I have tried making the persistence store permanently attached (in the development environment) but this returns a different error that implies that a permanently attached database is not allowed - so I assume that the persistence service HAS to have a detached database - Am I correct?
I have tried a UNC naming that is the same on both the machine with the server and the client machine e.g. \MACHINEwwfWorkflowPersistenceStore.mdb - but that still returns an error - Is that not allowed? (or is that not allowed) - does the file path for an attached database have to be recognisable by the client machine, the server machine or both?
MUST the User Instance be True or False or does it not really matter
It is probably obvious that I am not confident in the whole area of connection strings and the effect of different parameters and the truth is I am not certain that I have not completely confused the SQL Server with the various attempts I have made.
Is there someone who could confirm that I am in the right area and could give me an example of what SHOULD work in a situation I have described so that I know that I am roughly right and to keep trying or I am barking up the wrong tree?
I've created a sql statement that retrieves number data from various table joins. The number data is then grouped according to various categories. What I need to do is to calculate the average of all the number data in a particular group. How do i go about this? Once calculated, the average needs to be displayed under the data.
For example, the report will list say five numbers (some sets may have more, it depends on how much data is returned based on the query), then under the five numbers, the average is given
2 4 3 6 0
Average: 5
What technique is best? Do I have to calculate the numbers in sql or do I need to configure the report to calculate the average? If so, how? Can someone show me step by step how to do averages for a set of data in the reporting services?
I am completely new to doing reports, I'm just a hobbyist, and I've only used databases to retrieve basic data, but not make manipulations for reports.
Hi,I would like to know if its possible to add/subtract/multiply/divide values between a cell in a database and a textbox/label on a web form? how would I go about doing this? Also, I would like a number from a cell to appear in a label when a page first loads. How can I achieve this?
I am having 4 Columns Qty decimal(12,3),CF1 Decimal(12,3),CF2 Decimal(12,3),Flag TinyInt.
I want to perform following without using case if it is possible.
When value of Flag is 0 then Qty*(CF2/CF1) When value of Flag is 1 then Qty
And i Don't want to use any functions like isnull,NullIf,IIF even not union or union all.How to do this calculation without using any function.
Actually i am having more then 100000 rows in table and if i use functions then my index might not be called.,that why want to avoid cases and functions.
When I am executing a query that uses a mathematical function on values from 2 tables the query takes much longer than the same query that uses values from 1 table, even though the join remains the same.
Why is this happening? Is there a way to bypass this problem?
Long query ( values from 2 tables ) : SELECT MAX ( ( SIGN ( attribute.keyValue- ( -2027587559 ) ) *SIGN ( attribute.keyValue- ( -2027587559 ) ) -1 ) *-1*data.val ) AS maxVal FROM DATA data, ATTR attribute, TREE_ELEMENT elm, TREE_ELEMENT subject WHERE data.elmId=elm.id AND attribute.keyValue IN ( 345647222,1569153803,1569146115,-2027587559 ) AND subject.id=elm.subjectId AND subject.name = ‘test’
Short query ( values from 1 table ) : SELECT MAX ( ( SIGN ( data.keyValue- ( -2027587559 ) ) *SIGN ( data.keyValue- ( -2027587559 ) ) -1 ) *-1*data.val ) AS maxVal FROM DATA data, ATTR attribute, TREE_ELEMENT elm, TREE_ELEMENT subject WHERE data.elmId=elm.id AND attribute.keyValue IN ( 345647222,1569153803,1569146115,-2027587559 ) AND subject.id=elm.subjectId AND subject.name = ‘test’
1. Is it legal and OK to use a MSDN SQL copy on a production environment or is it strickly for test environments ??
2. If I own a legal copy of SQL 7 with 5 cals, can I legally use SQL MSDE and have more than 5 people access my SQL server or am I also limited to 5 users as my original ??
My store Procedure is not save in Strore Procedure folder at the time of saving it give me option to save in Project folder and file name default is SQLQuery6.sql when i save it after saving when i run my store procedure
exec [dbo].[SP_GetOrdersForCustomer] 'ALFKI'
I am getting below error :
Msg 2812, Level 16, State 62, Line 1 Could not find stored procedure 'dbo.SP_GetOrdersForCustomer'.
I have some tasks that I need to accomplish within T-SQL but cannot find a means to accomplish them.
They are..
1. Check for the existance of an external text file.
2. Count the number of rows in an external text file.
3. Be able to run the BCP command from within T-SQL. I am currently using the BULK INSERT command which works fine but it does not allow the following..
I am tying to call BCP to output the contents of a table to a text file from with in a stored procedure. The procedure will be called from an ASP page ... My question is were does the file get created ??? I want to create the text file on server ONE and SQL server is running on server TWO and IIS is running on server THREE... do i have to have a drive letter mapped to server ONE and if so is it mapped on the SQl server or the IIS server ....
ie: exec master..xp_cmdshell bcp db..table out h:est.out -Uxx -Pxx -Sx

I have two questions, 1) Could anyone please point me in the right direction concerning information pertaining to NT Server Enterprise Edition verses NT Server Workstations. We are having problems running SQL Server 7.0 and the Enterprise Edition together on the same machine and was wanting to find information about compatability issues, if there are any, 2) I, on a SQL Server 6.5 database shrunk it by 2 Gb. When I looked to see if SQL Server released those 2 Gb back to the hard drive, I was amazed that it didn't! Did I miss something or will SQL Server 6.5 not release the space because of the initial set-up. And why did SQL Server 6.5 automatically take the space from the Transaction logs when neither of the devices were specified? Is the Transaction Log the default area for shrinkage?

1. When we create DTS in SQL Server through DTS designer, where are they stored physically? 2. What would be the best way to modify a DTS without using DTS designer? 3. Is there any other way to create DTS apart from DTS designer and Visual Basic? 4. Is there any website which has detailed information for DTS? (which has more FAQs like above?)
In our production environment, we keep changing the servers frequently, and everytime that happens, I have to change the connection properties in all the DTS going to them one by one.
I am not too familiar with SQL Server, but my supervisor gave me the task of finding out the difference between SQL Enterprise and SQL Standard. He also asked me to research the difference between processor licences and client access licences. I will use the Internet as a resource, but I would also like to hear the opinions of someone who uses these programs or is knowledgable about them. So please any suggestions or any useful links would be very helpful.
I have two questions. 1) If a database is suspect we can have that trace from sysdatabases.There is a column named status.My question is in case of suspect datatbase what will be value in the field status of sysdatabases? 2) The password of an user login(created by using sp_addlogin stored procedure or any other way) is stored in the table sysxlogins of master database.The password is stored in a varbinary format.How can I get the actual password(means in a char format)?I mean how can I convert the varbinary value to a readable format?
Hi All, I am new in SQL SERVER 2000.I have few questions - 1) WHAT WILL I DO TO TRUNCATE THE SIZE OF A TRANSACTION LOG? 2) WHAT WILL BE THE STEPS OF BUILDING THE MASTER DATABASE? 3) WHAT WOULD BE THE PLAN OF ACTION WHEN SQL DOES NOT STARTS UP? 4) WHAT WOULD BE MY PLAN OF ACTION WHEN SQL DB GETS CORUPTED OR STARTS IN A SUSPECT MODE?
Could I do periodicity backups to another computer(mediaserver) using VDI??
I mean , Could I config a Virtual Device so that I can do backups like disk or tape, I can use 'backup database ...to virtual_device='...' ' to do backup to another computer(mediaserver)? suppose that I have finished the interface of mediaserver.
If this is impossible,how can I do periodicity backups to another computer??
I have finished a program using VDI that can do backup to another computer,and I know how to do periodicity backups to disk or tape. but I am puzzled about the periodicity backup using VDI.
I am putting together a proposal for my church, the current DB software (Access) has been outgrown. One proponent of a no name brand software insists that to implement SQL could take a year and a team of programmers, is this true??
Hi Could any one tell me the answers for these questions.
1. how do we troubleshoot a datbase if it is in suspect mode.What is the reason for a database to be in suspect mode. 2. how can we move a file from C drive to D drive, so that the file location in C drive is completely moved . 3.In a particular primary file group there are many objects. How can we move some of the objects from this primary file group in to another file group. 4. can we install a sql server on a remote server so that it will not ask any inputs like domain name, authentication modes. . 5.If we want to implement clustering , can we use the virtual ip address on clustering as the ip address of our system or we have to use another ip address for clustering 6. In 2000 we have DTs package.can we run the same DTS package in 2005.
Hi Im relatively new to ASP/SQL and have been thrown into the deep end by work. Ive got courses to go on, but not for another 3-6months.
Ive got an ASP file calling a database using SQL. Once you hit the "go" button, it puts this data into an Excel file, under a new window (still showing the asp file in the address bar).
It currently shows:
1) Item numbers that end in "0" i.e. 3.10, 12.20 appear as 3.1 and 12.2 respectively in the Bill of Materials … i.e. being treated as decimals … I need them to show-up as text. ************************************************** ******************* 2) When saving the spreadsheet … it would be good to get "X" to set the default file name to: <Quote ID>_<Customer>_<Platform>_<version>.[xls|pdf] ************************************************** ******************* 3) When a spreadsheet is displayed, it is in an editable Excel format. Is it possible to lock the file automatically when its opened or password protect it? ************************************************** ******************* 4) If a spreadsheet window is open and you try and open a new one, the old one pops-up/is still there. Need to be able to close the old one and re-open a new one automatically.
If necessary i will post the code. Any takers? Thanks
I need help with a few sql questions, but you need to look at picture containing the tables and the relationships between them. How do I post or upload the picture first?
Hi all,I'd like to know if it's possible to sort twice in a same SQL query.I use SQL for retrieving Data into an Excel Spreadsheet.(Excel 2000 or XP) and to paste the queries results into an Excelspreadsheet.1. I tried to sort by date and the only way was to use the serail numberinstead of the litteral nameI tried SELECT * FROM [Sheet1$] Where [Date] <= 07/20/2003"but this does not work.I then tried SELECT * FROM [Sheet1$] Where [Date] <= 37822" and itworks.Do you know a way to use 07/20/2003?2. I need to sort my data twice, first by name and second by date. Is itpossible to sort twice in one query?Something like:"SELECT * FROM [Sheet1$] Where [Date] <= 07/20/2003 ORDER BY [NAME] ASC,ORDER BY [DATE] DESC"3. Even if the first row of my Excel sheet includes the headers, I cannot perform a query other than SELECT * FROM, for exemple, SELECT [NAME]FROM, does not work. do you know how to do that?Thanks in advance for sharing your experience,Phil*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
1. If the TempDB Database is deleted from MS-SQL Server what willhappen..?2. How to insert a not null column in an existing table withrecords..?3. If a table is deleted, what will happen for the Stored proceduresand Views, which that table reffered..?
Hi All, I was asked couple of questions yesterday and I thought I had to still learn a lot. Questions sound very normal but as for as I am concerned, don't know the answers hence this forum. Please advise. Here the questions asked to me 1) A simple insert into the table (could be from .net application or query analyzer) takes 10 minutes and times out, does not do any thing. What could be the reason and how would you identify and resolve the problem.
2) A simple select from table taking 10 minutes( assuming there are only there columns in the table,those are, id, name, description) id being identity column and has got index as well. What could be the reason and how would you identify and resolve the problem?
3) How would you change the identity column value or can we change the identity value and how?
4) How would you use the shared, update, exclusive locks in the sql statement.?
i have started developing on DTS recently. and i have a few question about "How-To" issues.
Hope you guys can help
1) I noticed, whenever i want to "redirect row" whenever an error happen, i need to set my AccessMode to OpenRowSet... This mode as i noticed, cant be used when i am tranferring data into a sql table which has primary key set
e.g. Ms Access which has identity -> SQL table with PK set
Is there anyway, to capture the row error in my situation?
2) Another question is, in a data flow... can i have a source which has multiple output arrow.
The <Protect Sensitive Data Using Encryption in SQL Server 2005> said : If regenerate service master key with "FORCE" option, the keys protected by old service master key are lost forever along with the data encrypted by them.
I create a master key in database and create a certificate protected by it.Then i use the certificate to encrypt some data.
The master key also exists and the encrypted data can by decrypt after i regenertate the SMK with force option. So i'm puzzled,I want to know what are the keys which protected by SMK , are they database master key?
