Single Unique Character Query

Oct 27, 2014

I have a huge database (20 columns and 56000 lines) and I need a query that can return each single unique character from all this database.

For example if character "a" appears at least one time in this database I need this query to show it to me.

T-SQL (SS2K8) :: Replace Multiple Occurrences Of Same Character With Single Character

Aug 6, 2015

I have the following scenario, The contents of main file are like :

ServerCentral|||||forum|||||||||||||||is||||||the||best
so||||||be|||||on||||||||||||||||||||||||||||||||||||||||||||it

And I need the output in the following form:

ServerCentral=forum=is=the=best

The logic being that multiple and consecutive occurrences of the special character, here - pipe , should be replaced by a single special character.

T-SQL (SS2K8) :: Replace Multiple Characters With Single Character In A Column?

Jun 21, 2012

I am trying to replace all special characters in a column with one special character.

Example:

Table: dbo.Employee
Column: Name
Name
-------
edwardneuman!"<]
mikemoreno)'>$:
JeffJensen"?>"

I am trying to get the namepart to the left of ANY special character. To achieve this, I am thinking of replacing all the special characters with a single special character so that I can find the first occurrence of that special character and grab left of the special character (SUBSTRING/CHARINDEX). This way I don't need to loop through all the special characters.

I am expecting the following results:

Name
-------
edwardneuman<<<<
mikemoreno<<<<<
JeffJensen<<<<

SQL Server 2012 :: Replacing Recurring Characters In A String With Single Character

Jan 20, 2014

I have a problem where I want to write a function to remove recurring characters from a string and replace them with a single same character.

For instance I have the string '12333345566689' and the result should be '12345689'. In Oracle I could do this with "regexp_replace('12333345566689', '(.)1+', '1')", but in T-SQL the only solution I could think of is something like this:

DECLARE @code NVARCHAR(255)
SET @code = '12333345566689';
SET @code = REPLACE(REPLACE(REPLACE(@Code, '1', '~1'), '1~', ''), '~1', '1');

and repeat this for 2 - 9. But I'm sure there is a more elegant version for this in SQL Server 2012.

Unique Constraint Violation On Single Cell Dataset

May 9, 2007

Hi,



I'm retreiving data from a SAP BW data source. In the dataset designer I can build a query that returns a single value, the data returns successfully in the designer. When I switch to the layout mode I can place the field of the datset in table / matrix / textbox. However when i switch to preview mode or deploy the report and try to see them in Report Manager the report fails to render with the following message:



Query Execution Failed for dataset 'XXX'

These columns don't currently have unique values.



Its a single cell datset?!?!



I can successfully retreive data from other SAP Infocubes and queries. I also cannot replicate the error using a SQL Server datasource. The stack trace error looks like this:

SQL Search :: Full Text Search With Single Character Returns All Rows

Jul 21, 2015

Our clients want to be able to do full text search with a single letter. (Is the name Newton, Nathan, Nick?, Is the ID N1, N2...). Doing a single character full text search on a table work 25 out of 26 times. The letter that doesn't work is 'n'. the WHERE clause CONTAINS(full_text_field, ' "n*" ') returns all rows, even rows that have no 'n' in them anywhere. Adding a second letter after the "n" works as expected.

Here is an example

create table TestFullTextSearch (
Id int not null,
AllText nvarchar(400)
)
create unique index test_tfts on TestFullTextSearch(Id);
create fulltext catalog ftcat_tfts;

Newline Character In Query

Can I use a newline character in my query? I want to dynamically generate a statement, split on several lines. Simple example:

declare @cmd varchar(100)

Unique SQL Query... Help!

Jan 14, 2008

I have a field in my table named x_CFSNUM that is filled with various 4 digit numbers- ex: 0067, 0068, 0097, etc. These are not unique.

I would like to write a query that will tell me the sum of the times the highest number occurs.

For Example: If these were the numbers: 0067, 0067, 0067, 0089, 0094, 0095- The query would produce the quantity of "3" because 0067 is listed 3 times.

I know this is confusing. Please let me know if you need any clarification.

Thanks

SQL DISTINCT UNIQUE QUERY

May 4, 2007

I have a problem with a SQL SELECT query. As far as my research goes i figured out that UNIQUE is used when you have one column that you whant unique and DISTINCT is used when you have more than one column that you want to all be unique. But i have a query where i want just some of the columns to be unique and some not. Here is the full query (It's in a stored procedure):

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[rpt_ExecSum_Combined_4fields](@BondGroupID int)
AS SELECT DISTINCT
SUM(dbo.Bond.LoanAmount) AS SumOfBondValue, COUNT(dbo.Bond.BondID) AS CountOfBond, dbo.ProgressStepType.ProgressStepType
FROM dbo.BondGroup INNER JOIN
dbo.TransactionTable ON dbo.BondGroup.BondGroupID = dbo.TransactionTable.BondGroupID INNER JOIN
dbo.Bond ON dbo.TransactionTable.TransactionID = dbo.Bond.TransactionID INNER JOIN
dbo.ProgressStep ON dbo.TransactionTable.TransactionID = dbo.ProgressStep.TransactionID INNER JOIN
dbo.ProgressStepType ON dbo.ProgressStep.ProgressStepTypeID = dbo.ProgressStepType.ProgressStepTypeID
WHERE (dbo.BondGroup.BondGroupID = @BondGroupID)

GROUP BY dbo.ProgressStepType.ProgressStepType, dbo.ProgressStep.ProgressStepID
HAVING (dbo.ProgressStepType.ProgressStepType = 'AIP (Approval in Principle) received') OR
(dbo.ProgressStepType.ProgressStepType = 'Grants') OR
(dbo.ProgressStepType.ProgressStepType = 'Attorney') OR
(dbo.ProgressStepType.ProgressStepType = 'Feedback received from bank')
ORDER BY dbo.ProgressStepType.ProgressStepType

*********
With the DISTINCT it gives me a full set of unique values but what i want is this: Every CountOfBond may have more than one SumOfBondValue and they may be the same, but if there is more than one dbo.ProgressStepType.ProgressStepType the query should only read it once. In other words the dbo.ProgressStepType.ProgressStepType is a unique value and the rest not...

Please help, my boss is on my case :)

Unique Values Query

Apr 21, 2006

Hi, I have been asked to write some code that can check a large table for duplicate values in a non pk column. The table may have up to 1000000 rows. The PK column is an auto increment field. For performance reasons the column in question could not be set to unique values only for inserts, an algorithm is used to create unique no's before the insert but what I am doing is double checking that their have been no duplicates created accidently. If their are duplicates I need to know what rows they occurred on.

Thanks

Character String Query Doesn't Fill Dataset

Mar 15, 2007

I'm working in a ASP.NET 2.0 application with a SQL Server 2000 database on the back end.  I have a strongly typed dataset in the application that calls a stored procedure for the select.  I'm having trouble filling the dataset at runtime though.
I am trying to use a character string query because I setup different columns to be pulled from a table each time and in a different order so my T-SQL looks like this:
set @FullQuery = 'Select ' + @FieldsinOrder + ' from tblExample'exec (@FullQuery)
This works fine in query analyzer.  The results return and display correctly.  However, when I run the application, the dataset does not get filled.  It is like the results do not output to the application.
If I change the query to be a normal select it works.  For example:
select * from tblEmample
That works fine.  What is it about a select query setup as a character string and then executed that ASP.NET doesn't like?

Hmm - Unique Id Is In Binary Data - How Do I Query Against It?

Complex SQL Query - Finding A Unique Row By Lastdatemodified

Apr 14, 2008

HI all,

I am having a bit of difficulty trying to work how to write a query. I am normally only used to doing SELECT, UPDATE and DELETE queries ... the simple ones.

However I have come across a query whereby things get a lot more complex.

My company has an employee table with a way to store data that I have not been used to.

EMPLID, NAME, DATELASTMODIFIED, EmployeeStatus. (There are lots more but N/A)

The problem that I have is that there can be more than one row for an employee id. Therefore I cannot uniquely identify an employee id. Instead what I have discovered I have to use is to find an employee with the last modified date higher than the other rows with the same employee id.

The query I am trying to achieve is:


Code:

Count all employees that have an employee status of 'Employed'.

(Therefore counting only one employee per id rather than counting the same employee more than once)




The trouble is, translating this into a SQL query. I have tried to have a go but don't know how to query:


Code:

SELECT COUNT (DISTINCT EmplId)[
FROM Employeetable AS e
WHERE e.LASTDATEMODIFIED <And Stuck>
AND EmployeeStatus = 'Employed'



So I thought hmm lets pseudo code this, but then I get stuck into compelixty:


Code:

SELECT * FROM EmployeeTable WHERE EmployeeStatus = 'Employed'



int counter = 0;
ForLoop (EmplId)
{
LastDate Date
if(LASTMODIFIEDDATE > LastDate)
{
LastDate = LASTMODIFIEDDATE
}
//How do I return the value? Do I count the value?
}




Has anyone come across this issue before? Can anyone help it quite fundemental to what I have to query so help on this is highly appreciative.
