somebody please help me....
i'm using vb.net 2008 and SQL Server 2008...
the case is :
--------------------------------------------------
if i have data in one column like :
ASD654-100-CCCEEE4444-200-
what query can be used to get "CCCEEE4444" ????
|
|
|
|
|
SELECT SUBSTRING('ASD654-100-CCCEEE4444-200-',12,10)
Instead of string value give column name.
I Love T-SQL

it will not work.
coz i'll never know the starts index and the length of string.
coz the data is randomize.
example :
i want to get "ASD654" and "CCCEEE4444" from the data :
"ASD654-100-CCCEEE4444-200-"
or to get "QWEQWEQ" and "JJJLLL" and "PPPBBMMNN" from :
"QWEQWEQ-2000-JJJLLL-20-PPPBBMMNN-600-"
any idea? 
is there any query for looping?

Well, you have to use - as split char, by writting your own function then you can get result as you need.

how to split char "-" in SQL ?
is there a function for looping in SQL ?
teach me please...
i'm begging...
pleaseee..... 
|
|
|
|
|
Use SUBSTRING function
SELECT SUBSTRING([ColumnName],12,10) FROM [Table]
|
|
|
|
|
but i'll never know the starts index and the length of string.
coz the data is randomize.
example :
i want to get "ASD654" and "CCCEEE4444" from the data :
"ASD654-100-CCCEEE4444-200-"
or to get "QWEQWEQ" and "JJJLLL" and "PPPBBMMNN" from :
"QWEQWEQ-2000-JJJLLL-20-PPPBBMMNN-600-"
any idea?

For that you should write UDF, depends upon the random data you should define the things & write script for that.

i agree with blueboy where i have to use "-" as split char.
but the problem is i don't know how to split char using SQL Query.
and i think i need function for looping using SQL Query too.
can u help me pleaseee?

May be, for big works probably we need to write massive code(at least bunch of code).

Hi,
I suggest you create a split function
CREATE FUNCTION [dbo].[Split]
(
@delimited nvarchar(max),
@delimiter nvarchar(100))
RETURNS @t TABLE
(
id int identity(1,1),
val nvarchar(max))AS
BEGIN
declare @xml xml
set @xml = N'<root><r>' + replace(@delimited,@delimiter,'</r><r>') + '</r></root>'
insert into @t(val)
select
r.value('.','varchar(15)') as item
from @xml.nodes('//root/r') as records(r)
RETURN
END
Then cross apply to return your desired column. eg.
declare @tmp table (value varchar(100))
insert into @tmp values ('ASD654-100-CCCEEE4444-200-')
insert into @tmp values ('QWEQWEQ-2000-JJJLLL-20-PPPBBMMNN-600-')
select val
from @tmp
cross apply dbo.split(value,'-')
where id = 3

Hi All,
I'm very new to SQL Server 2008, and need a bit of help manipulating numbers.
I've got a int column holding numbers up to 11 digits. I need to do the following manipulation and use it in a SQL query. Basically, the first digit is transfered to the 3rd position on the right side.
12345678
23456178
or
1234
2134
The values are variable, there are even records with only a value of 1.
Thanks in advance.

- Cast the column to a
VARCHAR
- Reararrange the characters using the string-functions described here[^]

Hi,
How about...
<br />
declare @value varchar(11)<br />
set @value = cast(12345678 as varchar)<br />
select cast(substring(stuff(@value, len(@value)-1, 0, substring(@value,1,1)), 2, len(@value)) as int)<br />

Hello
See SQL
update wp_postmeta set option_value = replace(option_value, ‘nkhba.net\wordpress’, ‘alamhamasat.net’);
In the field option_value of wp_postmeta the following text
a:6:{s:5:"width";i:350;s:6:"height";i:280;s:14:"hwstring_small";s:23:"height='96' width='120'";s:4:"file";s:90:"D:\hshome\c259998\nkhba.net\wordpress/wp-content/uploads/2009/10/ououousoouououusoouso.jpg";s:5:"sizes";a:2:{s:9:"thumbnail";a:3:{s:4:"file";s:33:"ououousoouououusoouso-150x150.jpg";s:5:"width";i:150;s:6:"height";i:150;}s:6:"medium";a:3:{s:4:"file";s:33:"ououousoouououusoouso-300x240.jpg";s:5:"width";i:300;s:6:"height";i:240;}}s:10:"image_meta";a:10:{s:8:"aperture";i ;s:6:"credit";s :"";s:6:"camera";s :"";s:7:"caption";s :"";s:17:"created_timestamp";i ;s:9:"copyright";s :"";s:12:"focal_length";i ;s:3:"iso";i ;s:13:"shutter_speed";i ;s:5:"title";s :"";}}<
When I run that query above, it should affect the bold string (nkhba.net\wordpress) in the text above and change it to ("alamhamasat.net") corresponding to the query
But MySql responds me that (0) rows were affected.
please help

Could you try the statement below?
select replace(option_value, 'wordpress', 'Hello World')
from wp_postmeta;

i have one table(EMPLOYEE), in that columns are(Emp_Id,First_Name,Last_Name,Gender,Mobile_No,Email_id,Blood_Group);
in my front end page having 4 text boxies.that is emp_id,emp_name,mobile_no,blood_group.(here search buttion),
whenever we give id( or) name (or )mbno( or) bloodgroup(or) any combinations then result come with (Emp_Id,First_Name,Last_Name,Gender,Mobile_No,Email_id,Blood_Group)display.
i try some code but result is not coming.code is following
----------------------------
DELIMITER $$
CREATE PROCEDURE sp_srch(in empid varchar(10), empname varchar(45),mobileno varchar(15),bloodgroup varchar(5))
BEGIN
declare str varchar(255);
declare str1 varchar(20);
declare str2 varchar(20);
set str ="select Emp_Id,First_Name,Last_Name,Gender,Mobile_No,Email_id,Blood_Group from Employee where ";
if(empid!= '') then
set str= Concat(str ,"Emp_ID like '%", empid ,"%'and ");
end if;

end if;
set str1= (SUBSTR(str,-6));
set str2 = (SUBSTR(str,-4));

end if;
if(str2='and') then

end if;
select str;
END $$

EXEC (str)
or
sp_executesql str
But both are awful ways to implement a search query - and im betting you're passing textbox values directly into the SP - opening you up to sql injection attacks.
You should be doing it like the following, passing null for any params where you dont have a value (or not passing them at all, and taking the default, null)
CREATE PROCEDURE sp_srch(
@empid varchar(10) = NULL,
@empname varchar(45) = NULL,
@mobileno varchar(15) = NULL,
@bloodgroup varchar(5)) = NULL
BEGIN
select Emp_Id,First_Name,Last_Name,Gender,Mobile_No,Email_id,Blood_Group
from Employee
where (@empID IS NULL OR emp_id like '%' + @empID + '%')
and (@empName IS NULL OR first_name like '%' + @empName + '%')
and (@mobileno IS NULL OR mobile_no like '%' + @mobileno + '%')
and (@bloodgroup IS NULL OR blood_group like '%' + @bloodgroup+ '%')

Or passing 0 if is can be assumes that null and 0 are equivalent, this is then more fault tolerant
(ISNULL(@empID, 0) = 0 OR emp_id like '%' + @empID + '%')
Never underestimate the power of human stupidity

All the parameters were varchar, so passing zero is impossible.
However your point is a valid one - for numeric optional input I would most certainly have the default as zero and check for nulls in the way you suggested.
