IN Clause And CharIndex

Jan 20, 2004

Hi, The following stored procedure creates this error, "Syntax error converting the varchar value '17,18,405,408,406,493' to a column of data type int." I tried using a Convert and a Cast function but it still failed. I then read something about using the CharIndex function, but I can't figure it out. Any help would be much appreciated in getting this to work.
Thanks

CHARINDEX Issue

Mar 4, 2008

I have used CHARINDEX successfully to search for a substring going from left to right in a string, but how do I search from the end of a string and go backwards?

Here is a sample of the problem I am trying to solve. Here is a list of cities, some with two names and some with more than two. I need a way to extract only those cities with two names. I wanted to do this by locating the first space in the string and the last space in the string. If the first space equals the last space, then the city should only be a two word city. Otherwise it is a three name city or greater. So what string functions can I use to locate the first and subsequent spaces in a string?

Here is the current version of my SQL statement:

SELECT
City.City,
CHARINDEX (' ' ,City.City) AS First_Space
FROM
City
WHERE
CHARINDEX (' ' ,City.City) <>0

AND HERE IS A SMALL SAMPLE OF WHAT IS RETURNED:

MARINE CITY7
MARINE ON SAINT CROIX7
MARION CENTER7
MARION HEIGHTS7
HIGH RIDGE5
HIGH ROLLS MOUNTAIN PARK5
HIGH SHOALS5

Thanks to all who understand and can offer usable advice in my dilemma.

Jason.

CHARINDEX And STUFF/REPLACE

Jul 23, 2005

Hello,I need to be able to replace only the first occurance of a space characterin a column.Reason being is the data in the column I am trying to replace seems to haveumpteen space characters after each entry, so a simple replace functionwill replace all the spaces after it with what I want!I have thought of RTRIM to get rid of the spaces after and then replace, Ihave also thought of CHARINDEX to find the first occurance of a space andSTUFF to replace it.I have done my homework on these functions!But I am having trouble writing such a statement,I've never written a query which would use more then one function on onecolumn you see and I am getting confused!I'll tell you what I want to do in simple stepsReplace only the first found space in a name column, but then if a name hasa middle initial that will be a problem,Replace that with a dot.then concatanate '@emailaddress;@emailaddress2' after itso when SQLServer does the select it will bring back something likejoe.bloggs@emailaddress;emailaddressBut I guess I'd also need joe.n.bloggs@emailaddress;emailaddressThe data in the column looks like this at the momentjoe bloggsBut I guess there may come a time when we havejoe n bloggs, just to complicate things!What is your advice, and how do I write a query like thisI have been playing around with it in Query Analyser but as I said I amgetting confused and need some help if you don't mindThanks a lot to all who reply :-)RegardsJayne

Parse A String Using Charindex

Jan 15, 2008

Hi,

I've the following query. I'm using the yellow highlighted to join 2 tables, as these tables dont have a relationship between them.
The format of the name field is 'AAAA-BBBBBB-123'
here A will be only 4 chars, followed by '-' B can be any number of chars again followed by '-' and the last is the id which I'm using to do a join. This query will fail if the id is just 1 digit as its taking the last 3 chars as the id.
I dont know how to get the id from the right using charindex. Charindex would search for the first occurence of '-' from the right and get the chars after hypen i.e 123. How can this be achieved?

SELECT id AS 'ID',
name AS 'name',
sequence AS 'num'
FROM
FirstTable A
INNER JOIN SecondTable q
ON (CONVERT(INT,RIGHT(name,3))= a.id)
INNER JOIN ThridTable t
ON(t.id = q.id)
INNER JOIN FourthTable s
ON (q.name = s.name )
WHERE A.id = @ID
AND t.name=LEFT(s.name,((CHARINDEX('-',s.name))-1))
ORDER BY 'ID','num'

One more question on this is: Is this a good way of joining tables? If I dont use this I've a very large query containing unions. Which one should be bug-free and more efficient?

Thanks,
Subha

CHARINDEX BUG Returns Wrong Value

Jan 8, 2008

Hi

I've got a problem which looks like it might be a bug with the CHARINDEX function for Microsoft SQL Server.

The following line of code returns TRUE (1), but you would expect it to return FALSE (0):

SELECT CHARINDEX('Prausse', 'Prauße', 1)

Is there a way around this problem?

Thanks in advance for your responses.

OR-statement Returns True CHARINDEX Instead Of Name LIKE

Jun 11, 2013

I have this OR in a simple query:

Code:
DECLARE @searchString nvarchar(100)
SET @searchString = 'sample'
SELECT TOP(1) * FROM user
WHERE (user.identity LIKE @searchString OR
CHARINDEX(@searchString, user.firstname + ' ' + user.lastname) > 0)
PS: Handwritten...

If I pass in a searchString that matches the Identity and a different users lastname, this query will return the user with the lastname-match (which is wrong in my eyes, it should have matched the Identity first, then returned that row [Identity is a Primary key, indexed non-clustered]).

I've tried various things:
Removing LastName: (CHARINDEX(@searchString, user.firstname + ' ') > 0), then the returned row is from a matching identity, due to the lastname of a user was a match, but lastname was removed...so :P
Flipping the conditions around
Adding/removing paranthesis... without any luck.

Is there some option somewhere, to force the OR statement to return on the first true condition. I've always thought OR-statements (in a computer that is) breaked and returned true on the first true condition it found (from left to right, not bother to check the rest of the conditions...)?Or do I have to rewrite the query, with an IF, checking if the @searchString is a valid identity-format, if it is, query on the identity, if not query on the username...?

CHARINDEX With INT Data Type (Multiple Value)

Mar 24, 2014

I have a column that has 50 records and they are INT. I am trying to place them into a single parameter using the CHARINDEX using the IF Statement. I got an error saying convertinh from varchar to int type data.

Basically, this is what I did:
@RoomID varchar(max)

Then I declare it:

DECLARE @RoomId varchar(4)

SET @RoomID = 0

The IF part that I need to express this CHARINDEX function.

Then in Where clause I filtered it as:
WHERE r.roomid = @RoomId

Or what other way to handle INT data type and make them available for user to choose multiple value?

Help: About Charindex Function Doesn't Work With Variable

May 23, 2007

Hello to all,
I hope that somebody can help me.
I have written a sql query to search Partner. I have a wtcomValidRelationships Table. There are two Fields (IDMember(type: Int) and RelationshipIDs(type: varchar(1000)) in this table.
Example: 3418 has 3422 RelationshipID and 3422 has 4088 RelationshipID, if i want to check if there is a relationship between 3418 and 4088.
declare @IDM int;
declare @IDO char(100);
set @IDM = 3418;
set @IDO = '4088';
select B.IDMember
from wtcomValidRelationships as A, wtcomValidRelationships as B
where A.IDMember = @IDM and charindex(cast(B.IDMember as char(100)),A.RelationshipIDS) > 0
and charindex(@IDO,B.RelationshipIDs) > 0
Using this query i get nothing.
I try to use constant in charindex and i get result.
declare @IDM int;
declare @IDO char(100);
set @IDM = 3418;
set @IDO = '4088';
select B.IDMember
from wtcomValidRelationships as A, wtcomValidRelationships as B
where A.IDMember = @IDM and charindex('3422',A.RelationshipIDS) > 0
and charindex('4088',B.RelationshipIDs) > 0
So i think that charindex doesn't work with variable. But I must use variable. Can someone help me? What should i do ?
Thanks
Best Regards
Pinsha

Extract IP Address From Command String - Subscript And Charindex

The IP address length can vary, and the character after the IP is either a L or ,

Transact SQL :: Extracting Specific Data From One Field Using Charindex

I’ve got an issue with extracting specific data from one field using charindex. Here’s an example of the dataset:

Cl_nr Var_data

20059366 ;;1181750;31-12-2015;2;;;;;

Goal is to get the data after the 2<sup>nd</sup> ; until the next ; starts. Ideal would be to catch everything between the 2<sup>nd</sup> ; en 3<sup>rd</sup> ; (number should be 10 characters).

If I try to select this data just using charindex it only goes until it finds the first ; (of course), what’s the best approach in this?

Alternative For LEFT() And CHARINDEX() That Works With Text Data Type

Jun 26, 2007

I have a stored procedure that receives a list of ids, to get the emails of each of those ids. The problem that I'm having is that I'm using a char data type that is max length is 8000, but the contact lists are getting bigger and soon they might reach the variable max length. The contact list that I receive will look something like this "1234,67523,67875,789687,", I'm using "," as a separator. Right now what I do is this
@array_value = LEFT(@ContactList, @separator_position - 1)

The LEFT function doesn't work with data types text and ntext. But I'm in need of a string data type with a max length bigger than 8000. So I will apreciate if anyone knows of another function that does the same or similar and works with text data type, or any other ideas will be welcome.

Thanks,
Erick

T-SQL (SS2K8) :: Search For A String In Expression By Number Of Its Appearance - Charindex

Apr 3, 2015

I have written a query to search for a string in an expression by the number of it's appearance. Script is like this:

DECLARE @Expression VARCHAR(8000) = 'abcd_e_fgh',
@SearchString VARCHAR(10)= '_',
@OccuranceNumber SMALLINT = 1
DECLARE @SearchIndex INT = 0, @SearchIndexPrevious INT = 0, @Sno INT = 0
WHILE @Sno < @OccuranceNumber BEGIN

[Code] .....

Here i'm trying to search "_" in expression "abcd_e_fgh" where it is appearing for first time. it gives me 5 correctly. Now when i change the @OccurenceNumber to 2 or 3, it gives correct values 7 and -1 respectively. However now when i change it to 4, it gives me 5. So when it's trying to check for fifth appearance of "_", it's not actually giving 0 or -1 but repeating the value 5.
