Problem In Substring Function

Oct 11, 2005

Harshi writes "Hello SQL Team!!

I have a problem in Substring function. There is a Text data type field in my Table and it has large no of characters. I want to get the whole text as the result. The problem is its just giving me 300 characters from a row, as the result.

My statement as follows;

//============================================================

SELECT a.L2Topic, a.TopicIndex, a.L1Topic,
Substring(b.Des, 1, 900), b.PriceGroup, b.Price,
b.L1TopicIndex, b.Qty, b.OtherPrice,
c.Customer, c.Address, c.Date, c.ChassyNo,
c.VehicleNo FROM wshpTopicIndex a

LEFT JOIN wshpEstimateDetails b ON (a.EstimateID = b.EstimateID)
INNER JOIN wshpEstimateIndex c ON (b.EstimateID = c.EstimateID)

WHERE (b.RandomNo = a.TopicIndex) AND (a.EstimateID = 54)

GROUP BY a.L2Topic, Substring(b.Des, 1, 900), c.Customer, a.TopicIndex, a.L1Topic, b.Qty,
b.PriceGroup, b.Price, b.L1TopicIndex, b.OtherPrice, c.Address, c.Date, c.ChassyNo, c.VehicleNo

ORDER BY b.PriceGroup, b.L1TopicIndex

Can some one please help me to get rid of this problem??

Substring Function

Jun 20, 2008

it's early in the morning (well it is here anyway) and i need a shot of logic...

in the data base i'm currently working with i have a varchar field that holds either a number or a collection of numbers in square brackets. I need to extract the number or the first number in square brackets if it's a list. i know it's gonna be a simple one but my head just won't do it?? i'm trying with substring and charindex to determine the position of the '[' but just not getting it this morning

quick sample of what the data in this column may look like...


declare @t table (col varchar(30))
insert into @t
select '2' union all
select '[5] [4]' union all
select ' [12] [1]'


so i need to get...


col
-------
2
5
12


EDIT-
OK, so i get this to work but only if there is actually square brackets


declare @t table (col varchar(30))
insert into @t
--select '2'union all
select '[5] [4]'union all
select ' [12] [1]'

select col
,substring(col, charindex('[',col)+1, charindex(']',col)-charindex('[',col)-1)
from @t

Substring Function Can't Figure Out

Mar 5, 2008

I have a SQL query in Visual Studio (SSRS). I have a GL Account field that is formatted such as 100-400-123-1234. I wanted to use the substring function to pull out the second set of numbers which I can assign a location:

CASE WHEN substring(GlAccount,5,3)= '400' THEN 'Gainesville'
CASE WHEN substring(GlAccount,5,3)= '401' THEN 'Aledo'

I tried this and it comes back with syntax errors. Can anyone tell me how to approach this as I have a list of about 35 locations that I need to do like this. Thanks.

Performance Issue Using Left Or Substring Function

Oct 18, 2007

Hi,

I've tried the following query in SQL SERVER 2005, SQL Express and MACCESS.

select * from Table1 where drid in (SELECT DrID FROM Table2 WHERE (substring(PostalCode,1,3) IN ('B0E','B1P','B2H','B2Y','B3A','B3M','B4A','B4H','E1A','E1C','E1N','G0A', …)) and (substring(Telephone,1,3) IN ('204','250','306','403','416','418','450','506','514','519','604','613','705','780','807','819','902','905')))

The query is using two table. The first one Table1 is a table with user info. The second table Table2 has the info concerning a survey.

The Table1 containt approx. 6000 row and Table2 containt only 210 rows

The table structure from the different environment(MACCESS, SQL SERVER 2005, Sql Server Express 2005) are the same. The Table1 containt the field "PostalCode" and "Telephone".

When I execute this query on MACCESS and in SQL Server 2005 the result are approximately the same(Less than half second). But there a performance issue in Sql Express 2005. The query take an execution time between 7 and 9 secondes.

When I add a condition using a field from tblResponsePQ2Part1 ex: QA=1
like in the following query :
select * from Table1 where drid in (SELECT DrID FROM Table2
WHERE (QA = 1 substring(PostalCode,1,3) IN ('B0E','B1P','B2H','B2Y','B3A','B3M','B4A','B4H','E1A','E1C','E1N','G0A', …)) and (substring(Telephone,1,3) IN ('204','250','306','403','416','418','450','506','514','519','604','613','705','780','807','819','902','905')))
the query take an execution time of ~15 secondes!!!!

This issue only happen in Sql Server Express, on the others cases(mean MSAccess, Sql Server) the execution time is less than half second.

It’s weird because, Sql Express 2005 is supposed to be more performant
than MACCESS, and have the same performance than Sql Server Professional Edition. Please Help Me!!!!


Anyone have an idea why?

Error: Invalid Length Parameter Passed To The SUBSTRING Function.

Sep 28, 2007

Hi,

I am using a simple procedure to pivot results (found in another forum and adapted it). It is done on SQL Server 2005 server with all service packs. Procedure:
**************
ALTER Procedure [dbo].[EthnicityPivot] @StDate as Datetime, @EndDate as Datetime
as
begin
DECLARE @Teams varchar(2000)

truncate table ForEthnicPivot

INSERT INTO ForEthnicPivot
SELECT DISTINCT COUNT(ID), Team, Ethnicity
FROM dbo._EthnicityByTeamEpisode
where Startdate between @StDate and @EndDate
GROUP BY Ethnicity, Team

SET @Teams = ''
--// Get a list of the pivot columns that are important to you.

SELECT @Teams = @Teams + '[' + Team + '],'
FROM (SELECT Distinct Team FROM ForEthnicPivot) Team
--// Remove the trailing comma

SET @Teams = LEFT(@Teams, LEN(@Teams)-1)
--// Now execute the Select with the PIVOT and dynamically add the list
--// of dates for the columns
EXEC( 'SELECT * FROM ForEthnicPivot PIVOT (SUM(countID) FOR Team IN (' + @Teams + ')) AS X' )
end
************

I can call the function:
exec EthnicityPivot '01/01/2007','09/09/2007'

and it works fine in SQL analyzer, but when I want to use it in Visual Studio in a new report I am getting this error
message:

There is an error in the query. Invalid length parameter passed to the SUBSTRING function. Incorrect syntax near ')'.

Anyone had similar error and sorted it?

Cheers

The SqlDataReader (orderReader) doesn't blow up or anything until I call .Read() (and, as mentioned, this problem only occurs for one order). What could be happening here?

Jul 5, 2001

Hi all,
I have just started using SQL7 and quite dumb at it.
Here is my problem

i have tables ip_address and ip_subnets. both contains more than 20,000 records. Though ideally each subnet should correspond to only one ip address it is not so due to SMS inventory and remote clients configurations etc.

As an example If my ip address is 141.151.128.78 I need to select only 141.151.128.64 ( or atleast 141.151.128.*)as the valid subnet. In other words I need to compare upto 3rd octet and only if it matches with ip address then declare that as the valid subnet.
Pls note that ip addresses vary for each machine though there will 4 octets, I can't use character positions as the nos in each octet might vary from 1-255.

Any help would be greatly appreciated
Pasted here under is the query script I am playing around with charcter poistions which are not working in my favor. Just added to explain my problems in more clearer way
select distinct system_data.name0, System_IP_Address_ARR.ip_addresses0, System_IP_subnets_Arr.ip_subnets0, system_disc.client0 from system_Data, System_IP_Address_ARR, system_ip_subnets_arr, system_disc where system_data.machineid = System_IP_Address_ARR.itemkey and system_data.machineid = system_ip_subnets_arr.itemkey and system_data.machineid = system_disc.itemkey and system_disc.client0 = 1 and substring(System_IP_Address_ARR.ip_addresses0,1,10 ) = substring(System_IP_subnets_ARR.ip_subnets0,1,10) and substring(System_IP_Address_ARR.ip_addresses0,10,1 ) = '.' and System_IP_subnets_ARR.ip_subnets0 not in ('11%.%.%.%','12%.%.%.%', '10%.%.%.%' , '10.%.%.%' , '1.%.%.%') order by System_DATA.name0
