这似乎是一种更简单的方法，一种很好的递归算法
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) =

dbo.fnIntegerToWords( @Number % 10)

Case WHEN @belowHundred <> '' THEN 'and ' + @belowHundred else @belowHundred end
WHEN @Number BETWEEN 1000 AND 999999

您需要使用CASE声明：
SELECT intfield CASE WHEN 1 THEN 'First'
WHEN 2 THEN 'Second'
WHEN 3 THEN 'Third'
...other conversions...
ELSE '' END
FROM Mytable
修改：
下面3个字符数的工作代码。您可以在其下面添加所需的代码，用于2个和1个字符数字（基本上只需修改我写的内容并相应地更改SUBSTRING）。
基本上它将数字转换为字符串，检查有多少数字，然后相应地将其分解。
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) = 18 THEN 'Eighteen'
WHEN SUBSTRING(@v, 2, 2) = 19 THEN 'Nineteen'
ELSE '' END
ELSE '' END)
+ ' ' +
(CASE WHEN SUBSTRING(@v, 2, 1) = 1 THEN ''

此外，您可以CREATE TABLE使用数字及其名称。
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

没有固有的功能可识别数字并将其转换为单词。您需要根据业务规则构建一个case语句或存储过程/函数来为您完成。
