Sql Charindex Split String

Parse A String Using Charindex
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

SQL String Split With | Pipe
I've got a dilemma here. I'm currently reading records into EasyListBox (ELB) dropdownlist. The criteria in the dropdownlist is based on the select from another ELB dropdownlist. The problem is that the data contains rows with pipes that serve as separters. For example, one of the options that comes back now might be 123 | 456 | 789. I need to be able to make each of them its own row in the dropdownlist. Can anyone advice? Most records don't have any pipes and come throught fine, but some dont.
My code below: 
Dim sAT As String = Replace(elbAttribute.SelectedValue, "'", "''") 
Dim adapter As New SQLDataAdapter("Select Feature_Type As Attribute_Name, FEATURE_TEXT_VALUE as Attribute_Value, (select distinct FILTER_FAMILY_FEATURE_EXCLUDED.FEATURE_TYPE_ID from FILTER_PROFILES, FILTER_FAMILY_FEATURE_EXCLUDED, FAMILY_ALLOWED_FEATURE_TYPES, SHARED_FEATURE_TYPES, SHARED_FEATURE_VALUES where FILTER_PROFILES.FILTER_PROFILE_NAME = 'MAQ' And FILTER_PROFILES.FILTER_PROFILE_ID = FILTER_FAMILY_FEATURE_EXCLUDED.FILTER_PROFILE_ID And FAMILY_ALLOWED_FEATURE_TYPES.FAMILY_ID = FILTER_FAMILY_FEATURE_EXCLUDED.FAMILY_ID And FILTER_FAMILY_FEATURE_EXCLUDED.FEATURE_TYPE_ID = SHARED_FEATURE_TYPES.FEATURE_TYPE_ID And (SHARED_FEATURE_TYPES.Feature_Type_ID = SHARED_FEATURE_VALUES.Feature_Type_ID And left(FEATURE_TYPE, 4) <> 'CPLV' And Feature_Type = '" & sAT & "')) As ExclusionFlag From SHARED_FEATURE_TYPES, SHARED_FEATURE_VALUES, PRODUCT_FEATURE_VALUES Where PRODUCT_FEATURE_VALUES.FEATURE_VALUE_ID = SHARED_FEATURE_VALUES.Feature_Value_ID And SHARED_FEATURE_TYPES.Feature_Type_ID = SHARED_FEATURE_VALUES.Feature_Type_ID And left(FEATURE_TYPE, 4) <> 'CPLV' And Feature_Type = '" & sAT & "' UNION Select distinct Column_Name As Attribute_Name, SMALL_TEXT_VALUE As Attribute_Value, (select FILTER_ATTRIBUTES_EXCLUDED.EXT_ATT_ID from FILTER_PROFILES, FILTER_ATTRIBUTES_EXCLUDED where FILTER_PROFILES.FILTER_PROFILE_NAME = 'MAQ' And FILTER_PROFILES.FILTER_PROFILE_ID = FILTER_ATTRIBUTES_EXCLUDED.FILTER_PROFILE_ID And FILTER_ATTRIBUTES_EXCLUDED.EXT_ATT_ID = EXTENDED_ATTRIBUTES.EXT_ATT_ID) As ExclusionFlag From EXTENDED_ATTRIBUTE_VALUES, EXTENDED_ATTRIBUTES, PRODUCTS Where PRODUCTS.PRODUCT_ID = EXTENDED_ATTRIBUTE_VALUES.PRODUCT_ID And not SMALL_TEXT_VALUE is null And EXTENDED_ATTRIBUTE_VALUES.EXT_ATT_ID > 1499 And EXTENDED_ATTRIBUTE_VALUES.EXT_ATT_ID = EXTENDED_ATTRIBUTES.EXT_ATT_ID And Column_Name = '" & sAT & "'", myConnection) Dim dt As New DataTable()    adapter.Fill(dt) elbValue.DataSource = dt    elbValue.DataBind()

Help With SUBSTRING, CHARINDEX
I have a record with seven pieces of data, separated by commas:

a, b, c, d, e, f, g

I'm looking for some assistance on a good way to query the data into seven columns in the same result set or temp table (which will then ultimately be transformed to a CSV file for a required report).

I've used a combination of SUBSTRING, CHARINDEX, LEFT, and LEN and found several ways to separate the data into separate temp tables, but no way to get it into separate columns in the same table or result set.

Any advise would be most appreciated.

How To Use IF Or Case With Charindex?
Hi
I have a column col1 in a table having below strings. How do I get only the required part of the string as I explaind below. (Needed strings are followed by i.e as below).


txtString=duracell+alkaline+battery+&submit1=Search&OVR31&OVKWID=24137211531
i.e : duracell+alkaline+battery+

txtString=sealed+lead+acid+batteries+&submit&gclid=CMekn-fesZAodpzIcHA
i.e : sealed+lead+acid+batteries+

ID=3&Department=
i.e : 3

ID=22893
i.e : 22893

lngSessionId=837541253&pid=22714
i.e : 22714

CCcode=502&OrderId=INT10350&puramt=1773
i.e : INT10350

tduid=5c14526847651e9054552acc134e9a84&url=http://www.somedomain.co.uk/proddetails.asp?id=4204
i.e : 4204


Code I am using (Got this one from my other posting)

declare @QueryString nvarchar(255)

select@QueryString = 'ID=23456&Depatment='

selectsubstring(@QueryString, charindex('ID=', @QueryString) + 3,
charindex('&', @QueryString) - charindex('ID=', @QueryString) - 3) from Pageviews


1. But the above code only works if the string starts with 'ID='.
2. Because the col1 has strings starts with different letter this code fail to excute and gives error
3. Pathindex with regular express '(patindex('%[^0-9]%',v)-1)' cannot be used because it gets anynumber
in the string - string has mixer of numbers and letters

SO IF ANYONE LET ME KNOW HOW TO USE IF or CASE with 'charindex' or any other method to get the above said result would be greatfull.

CHARINDEX Issue
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.

CHARINDEX And STUFF/REPLACE
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

SQL7 Charindex Behavioural Changes
Folks,

when converting from SQL6.5 to 7.0, I have noticed a change in behaviour with the charindex if the datatypes used in the comparison are not the same.

Sample code:

create table x1 (col1 varchar(10), col2 int)
go
insert into x1 select 'monday', 10
insert into x1 select 'tuesday', 20
go
declare @x char(10)
select @x = 'monday'
select res = charindex(@x,col1) * col2 ,col1 ,col2 from x1
go

If you declare @x as varchar(10) not char(10), the sucker works (ie "res" comes back as 10 for monday and zero for tuesday not zero for both).

In an ideal world, there would be some undocumented setting somewhere that means I don't have to review 250+ procs before xmas!!

I can't see anything in BOL or the KB about this particular issue.

Cheers
Si

Is there a way around this problem?

Help: About Charindex Function Doesn't Work With Variable
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

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

String Or Binary Data Would Be Truncated. (only For 1700 Character String?)
I am trying to insert a row into a table of Microsoft SQL Server 2000.

There are various columns.















[SNO] [numeric](3, 0) NOT NULL ,
[DATT] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL
,
[DATTA] [char] (3000) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL
,
[CODECS] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL
,

The [DATTA] column is causing a problem. Even if I am trying to put only 1700 character string into [DATTA], the java code throws the following exception:-



StaleConnecti A CONM7007I: Mapping the following

Why is it throwing an exception even though the sum-total of this row doesn't exceed 8000 characters?

Can anyone please tell me what's wrong?

Name Split
Quick question.

I've got a CHAR (70) field called NAME that has a first and last name separated by a space. I want to split it into two fields FIRST and LAST -- with all the characters to the left of the space a first name and all the characters to the right of the space as last name. I couldn't find a string function that would let me do this simply (it may be right in front of me and I missed it).

Thanks in advance.

To Split Or Not To Split
I have a database with a "large" table containing date based information Basically they're reservations. I've thought about creating a new table and adding any records from past years to this table. For the most part only current reservation need to be searchable, but in some circumstances it would be useful to be able to search through the archive too. so, my questions!!!

Is 8,000 or so rows of data "large" and unwieldly in SQL terms?

Would splitting this data into 2 tables - one small table for current and future reservations and one larger archive table then using a UNION SELECT query to make archive information seachable be a significant improvment on server resources/load or am I making the whole thing more complicated than it need be as 8,000 rows of data is nothing to worry about.............

What did they say about a little bit of knowledge being a dangerous thing?

Thanks in advance of any guidance to a neophyte!!?

SPLIT() UDF
SQL UDF split()

The objective of this article is to help the SQL developers with an UDF that can be used within a stored procedures or Function to split a string (based on given delimiter) and extract the required portion of the string.

Scripting languages like VB script and Java script have in-built split() functions but there is no such function available in SQL server. In my experience this function is really handy when you’re working on an ASP application with SQL server as backend, whereby you’ll need to pass the ASP page submitted values to the SQL stored procedure.

To give a simple example, in a typical Monthly reporting ASP page – the users would select a range of months and extract the information pertaining to this date range. Classic implementation of this model is to have an ASP page to accept the input parameters and pass the values to the SQL stored procedure (SP). The SP would return a result set which is then formatted in the ASP page as results.

If the date range is continuous ie. JAN07 to MAR07 then the SP can typically accept a ‘From’ and ‘To’ range variables. But I’ve encountered situations whereby the users select 3 months from the current year and 2 months from previous year (non-continuous date ranges). In such scenario the SP cannot have a date range as input parameters.

Typically an ASP programmer would do is by having a single date input parameter in the SP and call the SP within a loop in the ASP page. This is an inefficient way of programming as contacting the database server within an ASP loop could cause performance overhead especially if the table being queried is an online transaction processing table.

Here is how I handled the above situation.

1.Declared one string input parameter of type varchar(8000) (if you’re using SQL 2005 then it is advisable to use Varchar(Max))
2.Pass the ASP submitted values as string, in this case the months selected by user would be supplied to the SP as a string
3.Within the Stored Procedure I’ll call the split() function to extract each month from the string and query the corresponding data

The basic structure of the stored procedure is as pasted below:-

CREATE PROCEDURE FETCH_SALES_DETAIL (
@MONTH VARCHAR(MAX)
)
AS
BEGIN
DECLARE @MONTH_CNT INT,@MTH DATETIME
SET @MONTH_CNT=1
WHILE DBO.SPLIT(@MONTH,',',@MONTH_CNT) <> ''
BEGIN
SET @MTH = CAST(DBO.SPLIT(@MONTH,',',@MONTH_CNT) AS DATETIME)
--<<Application specific T-SQLs>>-- (BEGIN)
SELECT [SALES_MONTH],[SALES_QTY],[PRODUCT_ID],[TRANSACTION_DATE]
FROM SALES (NLOCK)
WHERE [SALES_MONTH]= @MTH
--<<Application specific T-SQLs>>--(END)

SET @MONTH_CNT=@MONTH_CNT+1
END
END

Dbo.SPLIT() function takes 3 parameters
1)The main string with the values to be split
2)The delimiter
3)The Nth occurrence of the string to be returned

The functionality of the UDF is as explained STEP by STEP:

1.Function Declaration
CREATE FUNCTION [dbo].[SPLIT]
(
@nstring VARCHAR(MAX),
@deliminator nvarchar(10),
@index int
)

RETURNS VARCHAR(MAX)

Function is declared with 3 input parameters:-
@nstring of type VARCHAR(MAX) will hold the main string to be split
@deliminator of type NVARCHAR(10) will hold the delimiter
@index of type INT will hold the index of the string to be returned
2.Variable Declaration
DECLARE @position int
DECLARE @ustr VARCHAR(MAX)
DECLARE @pcnt int

Three variables are needed within the function. @position is an integer variable that will be used to traverse along the main string. @ustr will store the string to be returned and the @pcnt integer variable to check the index of the delimiter.
3.Variable initialization
SET @position = 1
SET @pcnt = 1
SELECT @ustr = ''
Initialize the variables
4.Main functionality
WHILE @position <= DATALENGTH(@nstring) and @pcnt <= @index
BEGIN
IF SUBSTRING(@nstring, @position, 1) <> @deliminator BEGIN
IF @pcnt = @index BEGIN
SET @ustr = @ustr + CAST(SUBSTRING(@nstring, @position, 1) AS nvarchar)
END
SET @position = @position + 1
END
ELSE BEGIN
SET @position = @position + 1
SET @pcnt = @pcnt + 1
END
END

4.1The main while loop is used to traverse through the main string until the word index is less than or equal to the index passed as input parameter.
4.2Within the while loop each character within the string is verified against the delimiter and if it does not match then local word count variable is checked against the input index parameter
4.3If the values are same ie., the input variable index and the word being processed in the while loop are the same then the word is stored in the @ustr variable. If the values does not match then the @position variable is incremented.
4.4If the character matches with the delimiter then the word count variable @pcnt is incremented along with the @position variable

5.Return the value
RETURN @ustr

I hope this article would benefit those who are looking for a handy function to deal with Strings.

i wirte a query to check if there is Relationship between two members.
Query: 
Declare @IDM int; Declare @IDO int; Set @IDM = 3387, @IDO = 4567;

Capitalize A Text String/String Function Related
Hi Folks:

How can I capitalize a string like 'JOHN DOE' into
'John Doe' with one SQL statement. SQL does provide
string function like LOWER(char_expr) which would
change the whole text string to 'john doe' and I don't
want that.
So far, in order to do that, I have to use a front-end
development language like 'Omnis' which has a
string function 'cap()' to capitalize the whole string,
then update the back-end SQL with the new string.
Thank you in advance for your time and advice.

Need Help With String Manipulation - Splitting 1 String Into Multiple Columns
Hello All,

I'm a non-programmer and an SQL newbie.  I'm trying to create a printer usage report using LogParser and SQL database.  I managed to export data from the print server's event log into a table in an SQL2005 database. 

There are 3 main columns in the table (PrintJob) - Server (the print server name), TimeWritten (timestamp of each print job), String (eventlog message containing all the info I need).  My problem is I need to split the String column which is a varchar(255) delimited by | (pipe).  Example:

2|Microsoft Word - ราย�ารรับ.doc|Sukanlaya|HMb1_SD_LJ2420|IP_192.10.1.53|82720|1

The first value is the job number, which I don't need.  The second value is the printed document name.  The third value is the owner of the printed document.  The fourth value is the printer name.  The fifth value is the printer port, which I don't need.  The sixth value is the size in bytes of the printed document, which I don't need.  The seventh value is the number of page(s) printed.

How I can copy data in this table (PrintJob) into another table (PrinterUsage) and split the String column into 4 columns (Document, Owner, Printer, Pages) along with the Server and TimeWritten columns in the destination table?

In Excel, I would use combination of FIND(text_to_be_found, within_text, start_num) and MID(text, start_num, num_char).  But CHARINDEX() in T-SQL only starts from the beginning of the string, right?  I've been looking at some of the user-defind-function's and I can't find anything like Excel's FIND(). 

Or if anyone can think of a better "native" way to do this in T-SQL, I've be very grateful for the help or suggestion.

Thanks a bunch in advance,

Chutikorn
