Anyone Have A Snazzy Way To Count Substrings?

May 3, 2004

Hi All,

I have a varchar that contains a comma-delimited list of integers, such as "12,34,56,78,123,1,123455".

I need a way to count the number of numbers in the string (or, perhaps, better stated as "I need a count of substrings") ;)

I'm thinking there must be a number of ways to calculate the number of numbers in my list of numbers, but I can only seem to come up with looping through the string/varchar and counting the number of commas, and then adding one to that final count.

Anybody know of a "cooler" way to do this? Everything I can think of involves stepping through a character at a time...

any (printable) thoughts?
THanks!

'group By' And 'substrings' Query Help

Jan 5, 2007

i have a table like this:


Code:

Product
id - varchar(10)
description - text



the ids are something like this
mod01-01
mod02-01
mod03-01
mod01-02
mod02-02
mod03-02
mod03-03
mod03-04
mod04-01
....

now, i am trying to group by and count all of the ids that end with '01',

i was thinking of something like
select count(id)
group by id
where id= ???

and the second query i need to make is one that counts not one but all the ids that end with the same last 2 digits but in one single query, how can i do that? as a possible hint, is that the only thing i KNOW that the last 2 digits can only be 01,02,03,04 and 05 but still im a bit stuck in here the result should look something like this

id total
01 4
02 3
03 1
04 1

or what suggestions can you give me for this query? even if you just help me with the first query, that would be great, thanks!!
thanks!!!

Replacements Of Substrings In Strings

Apr 19, 2006

This is not a piece of cake as I thought.

Have to replace few characters with few other characters in the string.

Now, I am using nested Replace:

(Replace(Replace(MyString,'Ü','UE'),'Ö','OE')

This example is simplified, number of replacements is more than eight of them.

Is there any other, more elegant, way to do this in just one command?

Taking A Filename Into Substrings

Apr 11, 2008

I have filename with the following format

461#Pipeline#0978541235#1.pdf

where # is the seperator between different data in the filename, in .NET i achieved to save the different data in the filename to seperate variables like this


Dim siebelId, accountNumber, docType As String

Dim counter As Integer = 0

Dim sites As String() = Nothing

sites = extension2.Split("#")

Dim s As String

For Each s In sites

If counter = 0 Then

siebelId = s

End If

If counter = 1 Then

accountNumber = s

End If

If counter = 2 Then

docType = s

End If

counter = counter + 1

Next s


How can i achieve this in SSIS where i can save these to variables for later use in an Execute SQL Task ?

How To Perform An Update To A Collumn With Two Substrings

Mar 22, 2005

I want to do the following in an update:

Update [table]
Set collumnName = Substring(collumnName, 1, 2) = '11' AND Substring(collumnName, 3, 5) = '00000'
Where (conditional statement)

SQL is not letting me perform the update because of the AND statement between the two Substring's. Is there anyway around this...is there anything else I can do to acomplish what I'm trying to do.

Thanks in advance everyone.

Transact SQL :: Search Substrings In Column Values

Jun 19, 2015

I have 2 tables in a SQL Server database:

Table A(Value), which contains some strings in the column "Value"

Table B(Key,Text), which also contains strings (in the column "Text")

Now I want to find all rows in B which contain at least one string of A and create a result table X with all found rows in B. B should contain the found keys and all found substrings for this key (separated with a comma)

The solution I am looking for may not use a Cursor and may not use the CONTAIN-Statement (fulltextsearch feature)..

Obtain Unit Percent With Unit Count Divided By Total Count In Query

Aug 21, 2007

The following query returns a value of 0 for the unit percent when I do a count/subquery count. Is there a way to get the percent count using a subquery? Another section of the query using the sum() works.

Here is a test code snippet:


--Test Count/Count subquery

declare @Date datetime

set @date = '8/15/2007'


select
-- count returns unit data
Count(substring(m.PTNumber,3,3)) as PTCnt,
-- count returns total for all units

(select Count(substring(m1.PTNumber,3,3))

from tblVGD1_Master m1

left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID

Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9

and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0

and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)

and v1.[Date] between DateAdd(dd,-90,@Date) and @Date) as TotalCnt,
-- attempting to calculate the percent by PTCnt/TotalCnt returns 0
(Count(substring(m.PTNumber,3,3)) /

(select Count(substring(m1.PTNumber,3,3))

from tblVGD1_Master m1

left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID

Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9

and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0

and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)

and v1.[Date] between DateAdd(dd,-90,@Date) and @Date)) as AUPct
-- main select

from tblVGD1_Master m

left join tblVGD1_ClassIII v on m.SlotNum_ID = v.SlotNum_ID

Where left(m.PTNumber,2) = 'PT' and m.Denom_ID <> 9

and v.Act = 1 and m.Active = 1 and v.MnyPlyd <> 0

and not (v.MnyPlyd = v.MnyWon and v.ActWin = 0)

and v.[Date] between DateAdd(dd,-90,@Date) and @Date

group by substring(m.PTNumber, 3,3)

order by AUPct Desc

SQL Query Automatically Count Month Events B4 Today; Count Events Today + Balance Of Month

Mar 20, 2004

I would like to AUTOMATICALLY count the event for the month BEFORE today

and

count the events remaining in the month (including those for today).

I can count the events remaining in the month manually with this query (today being March 20):

SELECT Count(EventID) AS [Left for Month],
FROM RECalendar
WHERE
(EventTimeBegin >= DATEADD(DAY, 1, (CONVERT(char(10), GETDATE(), 101)))
AND EventTimeBegin < DATEADD(DAY, 12, (CONVERT(char(10), GETDATE(), 101))))

Could anyone provide me with the correct syntax to count the events for the current month before today

and

to count the events remaining in the month, including today.

Thank you for your assistance in advance.

Name Count

Feb 26, 2007

I have an sql command for when you add a new name to the database it counts to see how many of the name entered to the textbox exist in the database. If the count is 0 then it will add the name to the table. Else it displays an error message.
This works fine for inserting a new name but on my update page where you may update the name I have the same code which on button click counts to see how many exist. But if you leave the textbox the same value and click the button the count obviously results in 1 and brings up an error message.
Is there a way I can do a count but not including the name that is currently the value of the textbox?protected void UpdateSharedArea(object sender, EventArgs e)
{
SqlConnection connection = new SqlConnection(docShare_ConString);

//Count the amount of area names that are the same as typed by user
SqlCommand existCheck = new SqlCommand("SELECT COUNT(doc_area_name) FROM document_area WHERE doc_area_name = @doc_area_name", connection);
SqlParameter areaname = new SqlParameter("@doc_area_name", SqlDbType.VarChar);
areaname.Value = AreaText.Text;
existCheck.Parameters.Add(areaname);

connection.Open();
int count = (int)existCheck.ExecuteScalar();
connection.Close();

//If the area name does not exist within the table
if (count == 0)
{
//Update name Cheers, Mark
