I have one field which stores alphanumeric values like
Schedule1
Schedule13
Schedule2
Schedule3
Schedule14,etc..
If I sort this in my query it will sort as follows
Schedule1
Schedule13
Schedule14
Schedule2
Schedule3
But I want records in following order
Schedule1
Schedule2
Schedule3
Schedule13
Schedule14
Is it possible to sort as above...?

Please post the query in which you sorted .With an ORDER BY clause you can get the results you desired.

Hope you're looking for this...
SELECT {ColumnName}
FROM {TableName}
WHERE {ColumnName} LIKE 'Schedule%'
ORDER BY CAST(REPLACE({ColumnName},'Schedule','') AS INT)

this is the query
SELECT [ScheduleID],ScheduleName FROM [Schedule] ORDER BY schedulename ASC
and this is the result
1 Schedule1
3 Schedule12
4 Schedule14
2 Schedule2
5 Schedule31
I want output in this format
1 Schedule1
2 Schedule2
3 Schedule12
4 Schedule14
5 Schedule31

And I just specified name as "schedule"....
It may be some other name also........So I cant find that name dynamically...

Ok 🙂 Try out this..
SELECT [ScheduleID],ScheduleName
FROM [Schedule]
ORDER BY CAST(CASE
WHEN ScheduleName LIKE '%[0-9][0-9][0-9][0-9][0-9][0-9][0-9]' THEN RIGHT(ScheduleName ,7)
WHEN ScheduleName LIKE '%[0-9][0-9][0-9][0-9][0-9][0-9]' THEN RIGHT(ScheduleName ,6)
WHEN ScheduleName LIKE '%[0-9][0-9][0-9][0-9][0-9]' THEN RIGHT(ScheduleName ,5)
WHEN ScheduleName LIKE '%[0-9][0-9][0-9][0-9]' THEN RIGHT(ScheduleName ,4)
WHEN ScheduleName LIKE '%[0-9][0-9][0-9]' THEN RIGHT(ScheduleName ,3)
WHEN ScheduleName LIKE '%[0-9][0-9]' THEN RIGHT(ScheduleName ,2)
WHEN ScheduleName LIKE '%[0-9]' THEN RIGHT(ScheduleName ,1)
ELSE NULL END AS INT)
Note: It would be better to implement the whole CASE part as a scalar function to completely encapsulate the logic and simply re-use the function wherever such sorting required.

Hi Manohar,
Try this
declare @abc table
(
name1 varchar(10)
)
insert into @abc values ('NAME1')
insert into @abc values ('NAME10')
insert into @abc values ('NAME11')
insert into @abc values ('NAME111')
insert into @abc values ('NAME2')
insert into @abc values ('NAME5')
insert into @abc values ('NAME3')
insert into @abc values ('NAME4')
insert into @abc values ('NAME6')
insert into @abc values ('NAME7')
--
select * from @abc
ORDER BY cast (substring(name1,(PATINDEX('%[0-9]%',name1)),len(name1))as int)

Thanks Arun....
Your code works fine.........
I will implement this in my procedure....:-P

HAH you beat me to it. I was trying the same thing myself. The solution posted can be used is all such situations. 🙂

Arun....
Ur logic works only in the case of alphanumeric values... I throws error in case of string
The error is
------
Msg 245, Level 16, State 1, Line 17
Conversion failed when converting the varchar value 'NAM' to data type int.

hi manohar,
if ur values are going to be mixed of string and alphanumeric and if u want to take care of order of alphanumeric then try this one
ORDER BY cast (case when (PATINDEX('%[0-9]%',SCH_NAME))>0 then substring(SCH_NAME,(PATINDEX('%[0-9]%',SCH_NAME)),len(SCH_NAME) )
else 0 end as int)
else
the first solution u got would still work okkkk
thanks

Yeah but it's easy enough to fix:
SET NOCOUNT ON
DECLARE @abc TABLE
(
name1 varchar(10)
)
insert into @abc values ('NAME1')
insert into @abc values ('NAME10')
insert into @abc values ('NAME11')
insert into @abc values ('NAME111')
insert into @abc values ('NAME2')
insert into @abc values ('NAME5')
insert into @abc values ('NAME3')
insert into @abc values ('NAME4')
insert into @abc values ('NAME6')
insert into @abc values ('NAME7')
insert into @abc values ('NAME_')
--
SELECT *
FROM @abc
ORDER BY RIGHT('0000' + SUBSTRING(name1, ISNULL(NULLIF(PATINDEX('%[0-9]%',name1), 0), LEN(name1)+1), LEN(name1)), 4)

It seems like all the function calls are a bit overkill IMO, unless I'm missing how they handle some edge-case.
A simple
ORDER BY len(column), column usually works for me for the generic case of "sorting alphanumeric values by numeric sorting".
