So I would like to split rows in my query based on if they match criteria and I really havent dealt with splitting in SQL only combining(which is usually what everybody does lol)
I'm trying to create a report and chart for a a manufacturing resource's activity for a given period (typically 30-90 days)
Jobs are created for the length of the run (e.g. 4 days). If the weekend is not worked and the above jobs starts on a Friday, the resource's activity needs to show 1 day running, 2 days down, 3 days running without the production scheduler having to make it two jobs. (A job can have multiple interruptions due to downtime). I have the jobs' schedules in one table and the downtimes in another (so think of the downtime as a calendar table--non working hours). Unusually, the end time is supplied with the downtime factored in.
So I need the query to create 3 datetime ranges for this job: Fri running, Sat,Sun down, Mon,Tues,Wed Running. Been going round in circles on this for a while. i'm sure there's an elegant way to do it: I just can't find it. I've found several similar post, but can't apply any to my case (or at least can;t get them to work)
Below is some sample date and expected results. I hope the explanation and example data is clear.
-- Create tables to work with / Source and Destination CREATE TABLE #Jobs ( ResourceID int ,JobNo VARCHAR(10) ,startdate SMALLDATETIME ,enddate SMALLDATETIME

Below is some sample data
|--------------------------J1------------------------------------| running |----D1-----| |-------D2-------| down |--J1--|----D1-----|-------J1------|-------D2-------|-----J1-----| result
|-----------------J1-----------------------| running |----D1-------| down |-----------------J1-----------------------| |----D1-------| result
I have a column with the following information in it. I need to split the column and parse the values. I have Parsed one single values from but, not multiple times.
Can it be possible to split the below string to NICK and SERVERS. Query which provides two columns, first column data should be NICK and other SERVERS.
Split function. I have records of multiple users, the last value of every record is a contact number (10 Digits- Numeric), I want a split function which can take the whole text and split the records on the basis of contact number.
In order words i want SQL to locate the contact number and move to the next record after that and so on till the end of the text.

I have a table with a varchar column that is delimited by char(227)+char(228) i.e.,
OrNo=7807ãäSeqNo=1ãäPStopType=PãäPCity=TillsonburgãäPSt=ONãäPZIP=N4G4J1ãäPAdr1=10 ROUSE STREETãäPAdr2=ãäPLat=42.8625ãäPLon=-80.7267ãäDStopType=DãäDCity=GaffneyãäDSt=SCãäDZIP=29341ãäDAdr1=121 PAN AMERICAN DRIVE
Looking for split function that accepts a multiple character value as a delimiter?
Generating the 4 lines is not the issue; I call 3 functions to do that together with cross apply.One function to get all dates between the start and end date (dbo.AllDays returning a table with only a datevalue column); one function to have these dates evaluated against a work schedule (dbo.HRCapacityHours) and one function to get the absence records (dbo.HRAbsenceHours) What I can't get fixed is having the correct hours per line.
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).
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!!?
I have one problem regarding sp and pass value in sp I am gating a value like Abc,Def,Ghi,
Now I want to split the whole pass value by “,� And fire one for loop to store value in database This things is done in asp.net web form but I want to do all process in sp So please guide me how I am write sp . The purpose is pass value one time so connection time is decrees and give fast perforce
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 have 5 dynamic rows each row consisting of 5 checkboxes & 5 dropdowns.I am concatenating the values of each controls in a row using a wildcard charater "~" and each row i am concatenating using "|".The complete string is then assigned to one hidden field and passed as sql parameter to the backend.
Please help in writing the split function to get the values of each checkboxes and dropdowns from the string in order to save them in separate columns.
Is it possible to split the following value in sql server ?
I have the value like 25 Email Accounts,50 Email Accounts in my sqlserver database. Here i need only the numeric value .ie 25,50.Is it possible? can any one give me the solution ..
I am using ASP.Net and C# backend is SQL Server 2000.

I have a procedure that is going to be called through asp pages. This procedure carries out instructions depending on whether customers wants to insert, update or delete their portfolios. Rules are as follows: 1. It should not allow duplicate portfolio name to insert. 2. If customer has reached their max limit of 20 portfolio they can't add. They may have to delete or update the existing portfolio first. 3. all the error handling is done and returned as output parameters.
Now coming to the question at present I have one procedure that does all these things. Should I split up the procedure and have three procedures handling the events seperately: 1 Insert 2 Delete 3 update The reason I am concerned is 1 procedure being hit so many times by concurrent users with varying events. I am concerned about performance issue and slowing down of the page. I do not have exact numbers of users at this point. But they would be in thousands or more. Thanks for any suggestions or advice you all might have to share. Hiku
What I have is a table with a primary key. Then I have 5 other tables with a relating key. No problems there.
I need to create a relationship with the primary table (primary) key who's data field is 25 charachters. I need to parse that out and have 3 charachters go to one, 2 to the other and so on.
Hi I need a stored procedure in SQL that will split a comma separated variable passed to it select a name for each value and return a recordset. Any pointers greatfully received. First attempt is dreadfully slow as I am opening recordsets each time
Function func_getFood() Dim rsfoodsql Dim foodoutput for x=1 to ubound(masterfoodarray)-2 set rsfoodsql= objconn.execute ("select foodname from tbl"&language&"food where foodID='"& masterfoodarray(x) &"'") if not rsfoodsql.eof then foodoutput=rsfoodsql("foodname") if not foodoutput="" then response.write foodoutput&"<BR>" end if end if next End Function
I have a large table that I'm planning on splitting out into 5 smaller ones. What I need to do is maintain some central repository for auto-numbering new records to make sure that no 2 records in different tables have the same unique ID. Thanks in advance!
Hi I have this string which might have a hyphen in it "-" What I want to do is if I get a hyphen then take all characters after hyphen else take only all the characters starting from the 5th position of the string How can this be achieved?
create table #sample (id int , value varchar(100)) insert into #sample values (1,'aaa,bbb') insert into #sample values (2,'ccc,ddd') insert into #sample values (3,'aab')
I have tried like this. but I cant execute my SP it ended up with errors.

My company use SQL server 2005 standard. considering deal with huge data, how if we want to split data (date range yearly or monthly) in order to ease transaction. that's simply for us to use query, but how if we want to split data that can be easily execute by operator (non-admin privilege). Is there any another way?
