Does anyone know how if it's possible to take an integer variable in SQL and convert it to the equivilent number of the form: First, Second, Third, Fourth etc?
Thanks
This seems like a simpler approach, a nice recursive algorithm
CREATE FUNCTION fnIntegerToWords(@Number as BIGINT)
RETURNS VARCHAR(1024)
AS
BEGIN
DECLARE @Below20 TABLE (ID int identity(0,1), Word varchar(32))
DECLARE @Below100 TABLE (ID int identity(2,1), Word varchar(32))
INSERT @Below20 (Word) VALUES
( 'Zero'), ('One'),( 'Two' ), ( 'Three'),
( 'Four' ), ( 'Five' ), ( 'Six' ), ( 'Seven' ),
( 'Eight'), ( 'Nine'), ( 'Ten'), ( 'Eleven' ),
( 'Twelve' ), ( 'Thirteen' ), ( 'Fourteen'),
( 'Fifteen' ), ('Sixteen' ), ( 'Seventeen'),
('Eighteen' ), ( 'Nineteen' )
INSERT @Below100 VALUES ('Twenty'), ('Thirty'),('Forty'), ('Fifty'),
('Sixty'), ('Seventy'), ('Eighty'), ('Ninety')
declare @belowHundred as varchar(126)
if @Number > 99 begin
select @belowHundred = dbo.fnIntegerToWords( @Number % 100)
end
DECLARE @English varchar(1024) =
(
SELECT Case
WHEN @Number = 0 THEN ''
WHEN @Number BETWEEN 1 AND 19
THEN (SELECT Word FROM @Below20 WHERE ID=@Number)
WHEN @Number BETWEEN 20 AND 99
THEN (SELECT Word FROM @Below100 WHERE ID=@Number/10)+ '-' +
dbo.fnIntegerToWords( @Number % 10)
WHEN @Number BETWEEN 100 AND 999
THEN (dbo.fnIntegerToWords( @Number / 100)) +' Hundred '+
Case WHEN @belowHundred <> '' THEN 'and ' + @belowHundred else @belowHundred end
WHEN @Number BETWEEN 1000 AND 999999
THEN (dbo.fnIntegerToWords( @Number / 1000))+' Thousand '+
dbo.fnIntegerToWords( @Number % 1000)
WHEN @Number BETWEEN 1000000 AND 999999999
THEN (dbo.fnIntegerToWords( @Number / 1000000))+' Million '+
dbo.fnIntegerToWords( @Number % 1000000)
WHEN @Number BETWEEN 1000000000 AND 999999999999
THEN (dbo.fnIntegerToWords( @Number / 1000000000))+' Billion '+
dbo.fnIntegerToWords( @Number % 1000000000)
ELSE ' INVALID INPUT' END
)
SELECT @English = RTRIM(@English)
SELECT @English = RTRIM(LEFT(@English,len(@English)-1))
WHERE RIGHT(@English,1)='-'
RETURN (@English)
END
You need to use a CASE statement:
SELECT intfield CASE WHEN 1 THEN 'First'
WHEN 2 THEN 'Second'
WHEN 3 THEN 'Third'
...other conversions...
ELSE '' END
FROM Mytable
EDIT:
Working code for 3 character numbers below. You can add the needed code below it for 2 and 1 character numbers (basically just modify what I wrote and change the SUBSTRINGs accordingly).
Essentially it converts the number to a string, checks how many numbers there are, then breaks it down accordingly.
DECLARE @n int = 515
DECLARE @v varchar(100) = CAST(@N as varchar)
SELECT CASE WHEN LEN(@v) = 3 THEN
(CASE WHEN LEFT(@v, 1) = 1 THEN 'One Hundred'
WHEN LEFT(@v, 1) = 2 THEN 'Two Hundred'
WHEN LEFT(@v, 1) = 3 THEN 'Three Hundred'
WHEN LEFT(@v, 1) = 4 THEN 'Four Hundred'
WHEN LEFT(@v, 1) = 5 THEN 'Five Hundred'
WHEN LEFT(@v, 1) = 6 THEN 'Six Hundred'
WHEN LEFT(@v, 1) = 7 THEN 'Seven Hundred'
WHEN LEFT(@v, 1) = 8 THEN 'Eight Hundred'
WHEN LEFT(@v, 1) = 9 THEN 'Nine Hundred'
ELSE '' END)
+ ' ' +
(CASE WHEN SUBSTRING(@v, 2, 1) = 2 THEN 'Twenty'
WHEN SUBSTRING(@v, 2, 1) = 3 THEN 'Thirty'
WHEN SUBSTRING(@v, 2, 1) = 4 THEN 'Forty'
WHEN SUBSTRING(@v, 2, 1) = 5 THEN 'Fifty'
WHEN SUBSTRING(@v, 2, 1) = 6 THEN 'Sixty'
WHEN SUBSTRING(@v, 2, 1) = 7 THEN 'Seventy'
WHEN SUBSTRING(@v, 2, 1) = 8 THEN 'Eighty'
WHEN SUBSTRING(@v, 2, 1) = 9 THEN 'Ninety'
WHEN SUBSTRING(@v, 2, 1) = 1 THEN
CASE WHEN SUBSTRING(@v, 2, 2) = 10 THEN 'Ten'
WHEN SUBSTRING(@v, 2, 2) = 11 THEN 'Eleven'
WHEN SUBSTRING(@v, 2, 2) = 12 THEN 'Twelve'
WHEN SUBSTRING(@v, 2, 2) = 13 THEN 'Thirteen'
WHEN SUBSTRING(@v, 2, 2) = 14 THEN 'Fourteen'
WHEN SUBSTRING(@v, 2, 2) = 15 THEN 'Fifteen'
WHEN SUBSTRING(@v, 2, 2) = 16 THEN 'Sixteen'
WHEN SUBSTRING(@v, 2, 2) = 17 THEN 'Seventeen'
WHEN SUBSTRING(@v, 2, 2) = 18 THEN 'Eighteen'
WHEN SUBSTRING(@v, 2, 2) = 19 THEN 'Nineteen'
ELSE '' END
ELSE '' END)
+ ' ' +
(CASE WHEN SUBSTRING(@v, 2, 1) = 1 THEN ''
WHEN SUBSTRING(@v, 3, 1) = 2 THEN 'Two'
WHEN SUBSTRING(@v, 3, 1) = 3 THEN 'Three'
WHEN SUBSTRING(@v, 3, 1) = 4 THEN 'Four'
WHEN SUBSTRING(@v, 3, 1) = 5 THEN 'Five'
WHEN SUBSTRING(@v, 3, 1) = 6 THEN 'Six'
WHEN SUBSTRING(@v, 3, 1) = 7 THEN 'Seven'
WHEN SUBSTRING(@v, 3, 1) = 8 THEN 'Eight'
WHEN SUBSTRING(@v, 3, 1) = 9 THEN 'Nine'
WHEN SUBSTRING(@v, 3, 1) = 1 THEN 'One'
ELSE '' END)
END
Also, you can CREATE TABLE with numbers and their names.
CREATE TABLE tblNumbers (Nmb int, NmbWord varchar(100))
INSERT INTO tblNumbers
VALUES (1,'first'), (2,'second'),(3,'third'), (4,'forth')
CREATE TABLE SomeTable (nmb int)
INSERT INTO SomeTable
VALUES (1), (1),(2),(3)
SELECT N.*
FROM tblNumbers N
JOIN SomeTable ST ON ST.nmb=N.Nmb
DROP TABLE tblNumbers
DROP TABLE SomeTable
This should work up to 999...

I Just Updated a function in MySql from 999 up to 999999999 number
this is the link to the original one:Reference
