एसक्यूएल सर्वर में वर्ड फंक्शन में नंबर कैसे लिखें?

एक सहायक संख्या तालिका का उपयोग करने पर विचार करें।

एनबी:यह एमएस एसक्यूएल

एक अनुक्रम तालिका बनाएं - इसमें वे सभी संख्याएँ शामिल हो सकती हैं जिनकी आपको आवश्यकता है या कम से कम 999 तक। मैंने इसे कम से कम तक सीमित कर दिया है लेकिन यह अतिरिक्त तर्क जोड़ता है।

CREATE TABLE [dbo].[Sequence]
    (
      seq INTEGER NOT NULL UNIQUE,
      word [varchar](25) NOT NULL
    )

INSERT INTO [Sequence] SELECT 0, ''
INSERT INTO [Sequence] SELECT 1, 'One'
INSERT INTO [Sequence] SELECT 2, 'Two'
INSERT INTO [Sequence] SELECT 3, 'Three'
INSERT INTO [Sequence] SELECT 4, 'Four'
INSERT INTO [Sequence] SELECT 5, 'Five'
INSERT INTO [Sequence] SELECT 6, 'Six'
INSERT INTO [Sequence] SELECT 7, 'Seven'
INSERT INTO [Sequence] SELECT 8, 'Eight'
INSERT INTO [Sequence] SELECT 9, 'Nine'

INSERT INTO [Sequence] SELECT 10, 'Ten'
INSERT INTO [Sequence] SELECT 11, 'Eleven'
INSERT INTO [Sequence] SELECT 12, 'Twelve'
INSERT INTO [Sequence] SELECT 13, 'Thirteen'
INSERT INTO [Sequence] SELECT 14, 'Fourteen'
INSERT INTO [Sequence] SELECT 15, 'Fifteen'
INSERT INTO [Sequence] SELECT 16, 'Sixteen'
INSERT INTO [Sequence] SELECT 17, 'Seventeen'
INSERT INTO [Sequence] SELECT 18, 'Eighteen'
INSERT INTO [Sequence] SELECT 19, 'Nineteen'

INSERT INTO [Sequence] SELECT 20, 'Twenty'
INSERT INTO [Sequence] SELECT 30, 'Thirty'
INSERT INTO [Sequence] SELECT 40, 'Forty'
INSERT INTO [Sequence] SELECT 50, 'Fifty'
INSERT INTO [Sequence] SELECT 60, 'Sixty'
INSERT INTO [Sequence] SELECT 70, 'Seventy'
INSERT INTO [Sequence] SELECT 80, 'Eighty'
INSERT INTO [Sequence] SELECT 90, 'Ninty'

फिर उपयोगकर्ता परिभाषित फ़ंक्शन बनाएं।

अब टेस्ट फंक्शन:
