I am developing an application in which when user did login and want to make his sub-login suppose 5 then at the time of making sub-logins the column that contains the number of sub-login 5 may be decremented by 1 itself and when he delete any one of his sub-login then this field will automatically incremented. This application is in C#.NET

Run an UPDATE query to increment or decrement whatever field is being used to store the number of sub-logins for a particular user, e.g. UPDATE mytable SET sublogin = sublogin +/- 1 WHERE ...

Any one knows how to use aggregate function on a multiple table. Following query is i am trying but i m not getting any success
SELECT up.UP_C_Date, up.UP_FN, up.UP_LN, up.UP_HEM, up.UP_CITY, up.UP_REG, up.UP_ZIP, up.UP_HPh, up.UP_STAT,count(cp.FK_UA_ID) FROM VTX_UP up, VTX_CRT_PM cp where cp.FK_UA_ID=up.FK_UA_ID;
How can I use aggregate function on a multiple table condition

There's no difference between using aggregate functions on a single-table query to a multiple-table query.
The problem with your query is that it doesn't have a GROUP BY clause. You use a GROUP BY clause to group similar items of data together. For each group of distinct data items, the COUNT function will return the count of items within this group. Without a GROUP BY clause, no grouping of data will occur and the COUNT function will always return 1.

You need to put a GROUP BY statement in containing the other fields.

I'm working on a project using SSRS and have a query that may accept a multiple valued integer as one of its parameters. I want to do something like this:
<br />
AND p.ID in (<br />
case @pList<br />
when '' then p.ID<br />
else (select id from dbo.fn_split_id_integer(@pList))<br />
end)<br />
which is fine when @Plist is empty but when it has multiple values in it the engine throws an error because multiple values are returned from the select statement, even though I'm using in rather than =.
Has anyone got any suggestions about how get this to work?
It definitely isn't definatley

AND p.ID in (<br />
case @pList<br />
when '' then p.ID<br />
else (select id from dbo.fn_split_id_integer(@pList))<br />
end)
The highlighted portion of the query is incorrect. Each branch of the CASE statement can only return a scalar value. In the ELSE clause, you are trying to return a table value.
You should change your query so that you JOIN p to the result of fn_split_id_integer().

Can you use the following?
select ...
where p.ID in (
select id from dbo.fn_split_id_integer(@pList)
union all
select ID from MyTable where @pList = ''
)
...
order by ...If @pList contains values then your fn_split_id_integer function will return a list of integer ids. If @pList is empty then the second part of the union will return all of the possible ids. I am assuming that ID is the primary key.
If your database is large then you might want to do a bunch of performance tests.

Hi all ,
i would like to replace a column data in my table ---- (Memeber_Id)
all the data in this field starts like '073444%'
However i would like them to start like '73444%'
only replace the first digit from starting with zero to the actual number.
Can you give me a script please?
Memberid
073367777
073868364
0757257457
I want them changed to
Memeberid
73367777
73868364
757257457
Thanks

Assuming you use varchar as the data type:
Update tablename Set Memeber_Id = substring(Memeber_Id,2,len(Memeber_Id-1))
Why don't you store the Memeber_Id in int column?
|
|
|
|
|
Thank you very much for your response.
Memeberid is Char(30) data taype.
When i run your script it comes with the following error
""""The conversion of the varchar value '7207513006 ' overflowed an int column. Maximum integer value exceeded.
Please advice
Thanks

Thank for your reply.
Its just a single table with no relationship to other tabel.
Having
Id int
message nvarchar(150)
Memberid Nvarchar(50).
I have to store memberid as nvarchar for some reason.
hope this helps to understand my table structure.

did not you say that it's char(30)?
|
|
|
|
|

can you post the exact query that you run and the exact error?
What database and version do you run?
This query should not give this kind of errors, no conversion to int occurs.
|
|
|
|
|
Yes it's true... the querry which was wriiten will not give such type of error.

Thanks man,
I am using SQL 2005. The table is not related to any other table.
I am just to change the data in memeberid and run the script you gave me.
Update tablename set memberid=substr(.........
Thanks

|
|

I think the problem is memberid is nvarchar(50) datataype not int.
is it?
|
|
|
|
|
no
and the function is substring not substr
Please post the complete query.
|
|
|
|
|
Update DATA Set Memeber_Id = substring(Memeber_Id,2,len(Memeber_Id-1))
|
|
|
|
|
Change it to:
Update tablename Set Memeber_Id = substring(Memeber_Id,2,len(Memeber_Id)-1)
len(Memeber_Id)-1 not len(Memeber_Id-1)
