In this post I will write a function that lists fibonacci series. It gets a parameter for max number then writes fibonacci series to that number.

First, we must create the function, the function’s code is below

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | CREATE FUNCTION fn_Fibonacci(@max int) RETURNS @numbers TABLE(number int) AS BEGIN Declare @n1 int = 0,@n2 int =1,@i int=0,@temp int Insert Into @numbers Values(@n1),(@n2) WHILE (@i<=@max-2) BEGIN Insert Into @numbers Values(@n2+@n1) set @temp = @n2 Set @n2 = @n2 + @n1 Set @n1 = @temp Set @i += 1 END RETURN END |

If you get succesful message then you can execute the code below

**Example-1**

1 | Select * from dbo.fn_Fibonacci(5) |

**The Result Of Code**

**Example-2**

1 | Select * from dbo.fn_Fibonacci(15) |

**The Result Of Code**

## Solution 2 For Fibonacci Sequence Function in Sql

1 2 3 4 5 6 7 8 9 10 11 12 13 14 | Create FUNCTION fn_Fibonacci2(@count int) RETURNS @numbers TABLE(number int) AS BEGIN Declare @n int,@i int=0 Insert Into @numbers Values(0),(1) WHILE (@i<@count) BEGIN Select @n = sum(number) from (Select top 2 number from @numbers order by number desc) as T Insert Into @numbers Values(@n) Select @i = count(*) from @numbers END RETURN END |

If you get succesful message then you can execute the code below

**Example-1**

1 | Select * from dbo.fn_Fibonacci2(5) |

**The Result Of Code**

**Example-2**

1 | Select * from dbo.fn_Fibonacci2(15) |

**The Result Of Code**
