SQL SERVER – UDF – Function to Convert Text String to Title Case – Proper Case

 Following function will convert any string to Title Case. I have this function for long time. I do not remember that if I wrote it myself or I modified from original source.

Run Following T-SQL statement in query analyzer:

SELECT dbo.udf_TitleCase('This function will convert this string to title case!')

The output will be displayed in Results pan as follows:

This Function Will Convert This String To Title Case!

T-SQL code of the function is:

CREATE FUNCTION udf_TitleCase (@InputString VARCHAR(4000) )
RETURNS VARCHAR(4000)
AS
BEGIN
DECLARE @Index INT
DECLARE @Char CHAR(1)
DECLARE @OutputString VARCHAR(255)
SET @OutputString = LOWER(@InputString)
SET @Index = 2
SET @OutputString =
STUFF(@OutputString, 1, 1,UPPER(SUBSTRING(@InputString,1,1)))
WHILE @Index <= LEN(@InputString)
BEGIN
SET @Char = SUBSTRING(@InputString, @Index, 1)
IF @Char IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&','''','(')
IF @Index + 1 <= LEN(@InputString)
BEGIN
IF @Char != ''''
OR
UPPER(SUBSTRING(@InputString, @Index + 1, 1)) != 'S'
SET @OutputString =
STUFF(@OutputString, @Index + 1, 1,UPPER(SUBSTRING(@InputString, @Index + 1, 1)))
END
SET @Index = @Index + 1
END
RETURN ISNULL(@OutputString,'')
END

Q- What will be the result of the query below? Explain your answer and provide a version that behaves correctly. select case when null = null then 'Yup' else 'Nope' end as Result; Ans-This query will actually yield “Nope”, seeming to imply that  null  is not equal to itself! The reason for this is that the proper way to compare a value to  null  in SQL is with the  is  operator, not with  = . Accordingly, the correct version of the above query that yields the expected result (i.e., “Yup”) would be as follows: select case when null is null then 'Yup' else 'Nope' end as Result;

Methods of Rank Rows in SQL Server: ROW_NUMBER(), RANK(), DENSE_RANK() and NTILE()

SQL Server provides us with a number of window functions that help us to perform calculations across a set of rows, without the need to repeat the calls to the database. Unlike the standard aggregate functions, the window functions will not group the rows into a single output row, they will return a single aggregated value for each row, keeping the separate identities for those rows. The Window term here is not related to the Microsoft Windows operating system, it describes the set of rows that the function will process. One of the most useful types of window functions is Ranking Window Functions that are used to rank specific field values and categorize them according to the rank of each row, resulting in a single aggregated value for each participated row. There are four ranking window functions supported in SQL Server;  ROW_NUMBER(),   RANK() ,  DENSE_RANK()  and  NTILE() . All these functions are used to calculate ROWID for the provided rows window in ...
