I have a column of telephone numbers that I am trying to get the most dialled number from. Can anyone help?
|
|
|
|
|
SELECT COUNT(*), TelephoneNumber
From MyTable
GROUP BY TelephoneNumber
You might want to put in an ORDER BY there too. If you are only interested in the highest value then:
SELECT TOP 1 COUNT(*), TelephoneNumber
From MyTable
GROUP BY TelephoneNumber
ORDER BY COUNT(*) DESC

Have you not heard of a search engine[^]? I typed your question into Google and got plenty of results.

What do you mean? I gave you an answer to your question.
If you don't know how to use a search engine to find answers to questions, I suggest you read this article[^]. Being able to use a search engine is pretty much a prerequisite for being a developer, so I suggest you learn fast.

Without seeing your C# code, it's hard to say what the problem could actually be.

connection = new SqlConnection(sql);
command = new SqlCommand("SP_Driver_WMile_Desc", connection);

You don't have anything in your code to tell it that you are using a stored procedure. You need to set the command type to CommandType.StoredProcedure. By default, it will try to execute this as a straight forward piece of SQL.

Hello!
I have a table which has a text column.
I need to modify this column for all rows that begin with some text.
How can I do it?
Thanks in advance!
Have a nice day!

UPDATE table_name
SET column_name = new_value
WHERE column_name like '%some text'
You should really read up on SQL if you have to ask this kind of questions. I suggest you read w3schools[^] articles on sql.

hello there,
im updating my table of about 1300 rows through C# but i always got error that server time out, then i copied the query and executed in the sql, and it took 25 secs that is too much
the query is written something like this :
update mytable set id = '1100001',deptid = 1, Cid = 1 where id = 'A1100001'
update mytable set id = '1100002',deptid = 1, Cid = 1 where id = 'A1100002'
update mytable set id = '1100003',deptid = 1, Cid = 1 where id = 'A1100003'
.
.
.
.
here are around 1300 lines like this,
about table
id nvarchar(25) PK
deptid tinyint
Cid tinyint
any idea how to speed up?? because 25 secs with core2 processor is too much
