whether you search for MeetingID =2 or for which where Meeting time is maximum

I think you want to get the all detail of meeting for which meeting time is highest. use following query

 SELECT *<br />
FROM mettings<br />
WHERE (hour*60+minute) =(select max(hour*60+minute) from mettings)

hope this helps

Why? Multiply the hour by 60 and add the minutes? If anything the other way round, surely?

the math is fine, it is calculating minutes since midnight.
On a big table it could be slow...

if there are multiple records, for which Metting time is equal to Highest Metting time, then it display all records.

However your suggestion is better.

Why did you give your database-password to the client? If he can't open the damn thing, he can't peek in it Smile | :)

actually we have to take the database back up and then we send it to client wherein client restore the database and make changes in web config of asp.net and uses the application

so is there any way where we can lock the database so that he can not peek in or encrypt the stored procedure

You can do smart things. Just make some table with sources of your procedures encrypted in some heavy algorithm. Then decode it outside of database (or even inside through some .dll with C# CLR integration) and execute it programmatically. Or you can write stored procedure that will exec your encrypted stored procedure Smile | :)

Wish you luck!

sql query and index

Hi all,

I am using query something like that

select * from table1 where column1 = 'value1' and column2 = 'value2';

and I have created the index like this

create index index1
on table1(
column2
);

i have used only one column because column2 is usually unique and can only sometimes repeat

Will the query will use the index or do i have to create index with both columns? I am using Oracle database.

Client would like to search.... Everything

The program I'm working on has a screen full of project data. The client wants to be able to run a "Google like" text search across all the text/lookup fields to return matching projects. Of course they want to be able to search on phrases also, matching all words, some words, etc.

The data is spread across around 10 tables. My first thought was to use Contains() in some capacity, but the db isn't full-text indexed. I'm not sure it would help if it was.

My remaining options seem to be:
1. Concatenate all the string info for each record into a field. Build up a custom select string with multiple Like searches, one for each word in the phrase to search. Run this with exec. Pretty sure the performance will suck on this one.

or

2. Concatenate all the string info for each record into a field. Select this data into a temp table and use a cursor to delete the non-matches for each word in the phrase to search. Pretty sure the performance will suck on this one also.

Are there any options I'm missing or has anyone got any better ideas?

Well, it ranges from sucky to extremely sucky, depending on the implementation. I'm hoping to write an article about this topic in the weekend Smile | :)

A fast tip; why not create a shadow-table that holds the same columns, as varchar-types? It's a lot faster than converting everything on the fly, and you can let the server insert a varchar-record with a trigger from the original table.

Good luck Smile | :)

thanks for ur reply..
yes, they exist.
and RoomID is primary key.
and if i modify the select statement (i just added braces and no other changes)
select (PresidentialSuite.RoomID,PresidentialSuite.DateWhenFilled,PresidentialSuite.DateWhenFree,PresidentialSuite.TimeForHouseKeeping)

then iam getting this error:
Msg 102, Level 15, State 1, Line 14
Incorrect syntax near ','.

where PresidentialSuite.Available='no';

The last select statement should return you two inserted rows in table HouseKeeping.
