What i need is to create a function that compares 2 strings variables and if those 2 variables doesn't have at least 3 different characters then return failure , else return success.
View 9 Replieshow SQL 2012 would treat a literal string for a comparison similar to below. I want to ensure that the server isn't implicitly converting the value as it runs the SQL, so I'd rather change the data type in one of my tables, as unicode isn't required.
Declare @T Table (S varchar(2))
Declare @S nvarchar(255)
Insert into @T
Values ('AR'), ('AT'), ('AW')
Set @S = 'Auto Repairs'
Select *
from @T T
where case @S when 'Auto Repairs' then 'AR'
when 'Auto Target' then 'AT'
when 'Auto Wash' then 'AW' end = T.STo summarise
in the above would AR, AT and AW in the case statement be treated as a nvarchar, as that's the field the case is wrapped around, or would it be treated as a varchar, as that's what I'm comparing it to.
Is there a limit on the size of the strings on both sides of the '=' sign for string comparison? If I have two varchar(max) strings, will the comparison be done beyond 8,000 characters?
View 1 Replies View RelatedIn my TSQL code i use a derived table to extract the value of account 321 to compare if they are the same that the SUM of my line invoice cost multiply by quantity line : Sum(fi.ecusto*qtt)
This is my script:
SELECT ft.ndoc [Doctype],ft.fno [Docnr] , Sum(fi.ecusto*qtt) [totalcostof my Invoiceline], xctb.conta [accountancy account],
sum(Case when ft.tipodoc = 1 then Xctb.ecre else Xctb.edeb end) as [Value of Cost of invoice in accountancy],
[DIF] = Sum(fi.ecusto*qtt) - Sum(Case when ft.tipodoc = 1 then xctb.ecre else xctb.edeb end)
[Code] ....
My problem is if i have more than on line on my invoice, for example 2 lines, the value of column [Value of Cost of invoice in accountancy] are duplicated, for 3 line invoice the value are multiply by 3.
We can use comparison operators with strings as well. Hence, I tried to use the following query on a SQL Server 2012 instance with the sample AdventureWorks2012 database (the collation of the database and of the column is the default:
SQL_Latin1_General_CP1_CI_AS):
USE AdventureWorks2012 ;
GO
--Returns 5 records
SELECT pp.Name
FROM Production.Product AS pp
WHERE pp.Name >= N'Short' AND pp.Name <= N'Sport' ;
GO
The query only returns 5 records. This despite the fact that the search is an inclusive search and the Production.Product table contains records that begin with "Sport".
Now, when I replace "Sport" with "Sporu" (just moving one character up in the alphabet to verify whether characters after the word have any impact on the search) gives me 8 records.
USE AdventureWorks2012 ;
GO
--Returns 8 records
SELECT pp.Name
FROM Production.Product AS pp
WHERE pp.Name >= N'Short' AND pp.Name <= N'Sporu' ;
GO
What's going on inside of SQL Server that allows it to fetch "Short-Sleeve Classic Jersey" for the starting word "Short" but prevents it from fetching "Sport-100 Helmet" for the ending word "Sport" despite the search being an inclusive search?
I have 2 CLR Functions, both do the same thing, and they seem to perform the same based on testing. I am working on building examples for the web, and considered putting both up but I think the use of the Regular Expression is more of a best practice. Any thoughts on this?

My only beef with the Regular Expression function is that Regular Expressions are often over the head of many people. I could provide both examples, and cross link them, but I am not sure about that. Any opinions?
Hi,
Assuming a table with a column defined char or varchar.
I have a SQL query like this :
Select * from table1 where column1='Building'
It returns the same result that
Select * from table1 where column1='BUILDING'
It is my understanding SQL Server (verison 7 or 2000, I tried on both) is lower/capital insensitive by default when it is installed. If I want SQL Server to be case-sensitive with my char or varchar columns, where can I set it?
Is it at database level or server level I can find this setting . What is the setting that control it?

We have some URLs within a bulk block of text some of which are very long. I need to identify rows where such urls exceed say 100 characters in length in amongst other text.So the rule would be return a record if within the string there is a string (without spaces) longer than 100 characters.
View 9 Replies View RelatedDear All:I encounter one problem when I want to implement my thought. My thoughtis that user want to search a record of someone but maybe user wouldtype wrong name or spell name wrong. I wish to compare the string whichuser inputed to the database column using "Socre Method". "ScoreMethod" has a variable "grade" to accumulate the score. I want toconvert the string to char array, and compare the char one by one. Ifthe string is more accurate , the grade is more high. At last, I choosethe most higher score record to show. How to do this thought with tsql?Could give me some tips or guide to learn? I will appreciate yourkindness, thanks.
View 6 Replies View RelatedOur dev team wants to introduce a complex key, which is made up of
EventDate datetime2(5) = ‘2015-10-22 10:19:59.12345’
ConsumerID bigint = 1234
SiteID tinyint = 15
EventDate will be converted to a bigint and then to a hex value
= 2015-10-22 10:19:59.12345 = 2015102210195912345 = 1BF714C8A0D4F699
ConsumerID will be converted to a hex value
= 1234 = 4D2
SiteID will be converted to a hex value
= 15 = F
The hex values will then be concatenated together and stored as a string (varchar). The application will handle the creation of the complex key
= ‘1BF714C8A0D4F699-4D2-F’
I am trying to argue against this approach and get them to store the values in their native form, in separate columns as a natural key.
To make matters worse, we need to use partitioning, where the partition boundary will be on a hexed datetime2(5) at weekly intervals. I was really hoping a proof of concept would show that hex string comparison could potentially put a row under a wrong partition, but so far, on an 8 million rowset, it is working fine.
For example, in the proof of concept, right partition boundary:
= '1BF398D53DFA1800'
(2014-12-15 00:00:00.00000)
contains rows
= '1BF3983242B9C000-1-2'
(2014-12-08 00:00:00.00000-1-2)
Through to
= '1BF398C373960580-2FAF3003-2'
(2014-12-14 23：59：00.00000-800010243-2）
The prior partition boundary is 1
= 'BF3983242B9C000'
(2014-12-08 00:00:00.00000)
How is this working, given that the string lengths (varchar) are different and the row value contains dashes and the partition boundaries are smaller in length without dashes? How varchar string comparison is working here?
I'm working on a program that reads in zip codes and then does some checking on them. Occasionally, the end user typos or transposes digits. It's easy enough to identify bad zip codes, but I would like to offer up a single recommendation. The problem is that there are often multiples to choose from. Is there a function or has anyone tried to figure out the delta between two strings?

I'm rewriting a huge FOR XML EXPLICIT procedure to use FOR XML PATH, and need to compare previous output to the refactored one, so i didn't mess up XML structure.
The thing is, i'm not sure that SQL Server will always generate exactly same xml **string**, so i'd rather not compare by:
WHERE CAST(@xml_old AS NVARCHAR(MAX)) = CAST(@xml_new AS NVARCHAR(MAX))
nor do i want to manually validate every node, since the generated xml-structure is quite complex.
compare xmls by their "semantic value" ?
I have three variables
DECLARE @QuantityID uniqueidentifier,
@LengthID uniqueidentifier,
@CostID uniqueidentifier
They are sent to the sproc as null. Since they could be null I need to exclude them from posting to a temp table
Example
DECLARE @QuantityID uniqueidentifier,
@LengthID uniqueidentifier,
@CostID uniqueidentifier
SET @CostID = NEWID()
SELECT @QuantityID as ID UNION ALL
SELECT @LengthID UNION ALL
SELECT @CostID
Two values are null. I want those excluded from this table
Here is the example of what I am trying to do:
DECLARE @QuantityID uniqueidentifier,
@LengthID uniqueidentifier,
@CostID uniqueidentifier
DECLARE @Temp as Table (id uniqueidentifier NOT NULL Primary key)
SET @CostID = NEWID()
INSERT INTO @Temp
SELECT @QuantityID as ID UNION ALL
SELECT @LengthID UNION ALL
SELECT @CostID
How do I insert into @Temp only non null values?
Hi all,I have created this simple Stored procedure. But it gives me wrong result when I pass a parameter to it. But if I hard
code it, it gives me the right result.
The I check if the field value of 'Email' is exactly equal to the parameter '@Email'.
The field 'Email' is varchar, and CID is integer.
CREATE PROCEDURE EmailExists @Email varcharASSELECT CIDFROM CustomersWHERE Customers.Email = @Emailreturn
Instead, if I check the value directly, it gives me correct answer. The the following code works fine when I typethe Email directly in the code.
CREATE PROCEDURE EmailExists @Email varcharASSELECT CIDFROM CustomersWHERE Customers.Email = 'tomyseba@yahoo.com'
return
Can anyone tell me the reason for it.
Thanking you in advance

I am comparing two fields one from our legacy table and one in our new table structure that should have identical text data. The new field has an assortment of ANSI characters where the legacy data did not have these. Is there anything I can do that will ignore all ansi character differences? The only route I can think of is just do a replace on each ANSI type on the new column but there are quite a few character types.

I have a User Defined Function in my SQL Server 2000 database which takes a string and adds an integer quantity to it. The function basically takes the string (string because of first character and spaces) and adds an integer to it creating a new number (starting number and ending number concept).If I pass in a string that has a letter for the first character, it works fine. However, if the first character is an integer it trims out all 0s and whitespace and ruins the necessary formatting. Note, the formatting is always the same - x xxx xxxx xx.
