I think he means to retrieve it in chunks so as to be able to display a percentage meter.

Does that include the stored proc you want that deletes all of the stored procs?
You need to do this drop procedure [proc_name] to drop a stored proc.
Create one line for each procedure unless you want to get all of the stored procs without knowing in advance what they are called. I'll leave you to work that one out. Hint: sysobjects

to delete all the procedure in your specified database, just execute the following line.
1. select 'drop proc '+name from sys.objects where type='p'
you will get list of procedure like
drop table proc1
drop table proc2
select all and execute
thats all

Create a cursor that loops through the system view INFORMATION_SCHEMA.ROUTINES or sysobjects
Get the name of the proc in the cursor
construct a drop procedure string DROP PROCEDURE [ProcName]
execute the string

I would suggest backing up the database before you start.
In object explorer go to the database go to the Programmability then Stored Procedures. Open the Object Explorer Details.
You can now script all the stored procedures so that when you delete them you have a copy.
Highlight the stored procedures to be deleted
Right click
Select Script Stored Procedure As/Create To/File
Give file name.
Now you can delete the files that are highlighted by right clicking and selecting delete.

DECLARE TblCursor CURSOR FOR
SELECT
[name]
FROM
sys.objects
WHERE
[name] like '%' + @fnd + '%'
and is_ms_shipped = 0
and [type] = 'P'
OPEN TblCursor
FETCH next FROM TblCursor INTO @proc
WHILE @@fetch_status = 0
BEGIN
SET @sql = 'DROP PROCEDURE ' + @proc
EXEC @sql
FETCH next FROM TblCursor INTO @proc
END
CLOSE TblCursor
DEALLOCATE TblCursor

Hi!
I'm updating a Table. Each time I update, a new record is created. But I want only one record to be created(I've to over write the existing record). My query is:
char query[512];
sprintf_s(query, 512, "UPDATE Current SET TeamID=(%d),Theme=(%d)", TeamSlectLst->getSelected(),ThemeSelectLst->getSelected()+1);
SQLdb.Query(query);
I'm using SQLite. I'm calling SQLite Query from C++. What modifications has to be done in the above Query? This may be a silly question. But don't neglect this, why because I mainly working with C++.

There seem to be several issues.
Current is a reserved key word for SQL Server (see http://msdn.microsoft.com/en-us/library/aa238507(SQL.80).aspx[^]).
Furthermore, a WHERE clause is appropriate as otherwise all rows would receive the new values.
UPDATE [MyTable] SET TeamID=21, Theme=59 WHERE Identifier=95
By the way, parameterized queries are to be preferred to plain text queries.

I am pretty sure SQLite is not a SQL server product. Which probably accounts for the lack of response!

I asked this question on StackOverflow, and learnt that Skype uses SQLite, but can anyone give me any info on the actual semantics of the database tables used?
Skype seems to use .db, .db-journal, and .lock files, as well as subdirectories full of .dat files for storing conversation histories.ces
Are the formats of these files available anywhere, or is there an open source library for accessing them that I can examine and possibly modify? I think several libraries allow the retrieval of conversation history, but I would like to also achieve insertion of conversation history records.

I have 55000 of member records in the database, I have a procedure in Sql Server 2005 to calculate all members commission. I Execute this procedure on first date of every month. This is a MLM Project, Commission of every Member depends on Member Hierarchi, So in the way to calculate commission consider all members in the Hierarchi, it takes 24 hrs to generation commission. In this process I has to execture procedure for 24 hrs in my local machine.
So, I need to assign task to server from client and disconnect from server.
Is it posible ? pls suggest me a solution....

I would set it up as a job in SQL Server, scheduled to run every month. I would also look at the procedure, 55k members and runs for 24 hrs seems a lot excessive.

This should not take 24 hours.
Without seeing your code I would guess you need to rethink the steps to get the result. By the description it sounds like you are trying to do it all at once. First find commission rate for all to a temp table then apply commission rate for the output.
Also as stated by others if not using SQL 2005 Express a job can be scheduled for the first of every month.

For that few of rows, there is no way it should take that long.

Lately I've been working an C# app that stores values in an Access db. One of the fields stores a time value. (7:30 PM)
Is there a more effecient way to store a time value than using the DateTime column? I will need to convert it to a DateTime value in the SELECT query.
Serious answers please. 
|

I'm a bit confused. 
You say that want a better way to store time in Access, but you will need to convert it to DateTime in your select statement. Then why not store it in a DateTime column to begin with ?
I worked for a Time and Attendace company for a while and what I've learned is that you always seem to need the date component along with the time because there is always the overnight shift worker. (11pm to 7am)
When you store the data in a DateTime column, the calculation of time difference is already built into those functions, you don't have to worry about crossing midnight etc.
My vote is to store the time in a DateTime column. 
I'm getting off my soapbox now. 
Best of luck with your project.

The key word here is "store". Access has a max capacity of 2gb.
DateTime types require 8 bytes for each field. Some Access developers have advocated using an int type for Date only values. This would be accomplished by storing the number of days since 1900 and using the DateAdd() function to convert the value to DateTime in the SELECT query.
I ask for serious responses!

Use a DateTime-field - that's what most people do, and that's where you can expect the most support. You can fit a whole lotta dates in those 2 Gb, and optimizing for space is a bit of a timewaster IMO.

Wow that's pretty serious! 
I certainly don't want to create a second curse by trying to eliminate the first one. Thanks for the reply.

I ask for serious design. Using Access for something when you are afraid of running into the 2gb limit is terrible. Use SQL Compact Edition or something else. I think the OLE automation date format is only 4 bytes.

I agree with Mr Gray, if you have to optimise for space using spit Access then you are using the wrong tool. Seriously change tools, there are many better options out there than spit Access
