In this post we will create more than 10 procedure examples. With this examples you can learn how to create a procedure, how to create procedure with parameters and how to create procedure with output parameter. Additionally we’ll learn how to run a procedure.

## 1-) Calling a Stored Procedure To Add Two Numbers With Input Output Parameters Example

In this tutorial we will learn how to add two number and return with output parameter in sql stored procedure. Once we must execute the code below and get succesful message:

1 2 3 4 5 |
Create Procedure AddTwoNumber(@p1 int,@p2 int,@Result int output) as Begin Set @Result = @p1+ @p2 End |

Before to execute the procedure we must define a variable to keep the result Than we can execute the Stored Procedure with any values you want and we can learn the result with select statement;

1 2 3 |
Declare @r int Execute AddTwoNumber 20,25,@r output Select @r as Result |

Result Of The Code : 45

1 2 3 |
Declare @r int Execute AddTwoNumber 5,7,@r output Select @r as Result |

Result Of The Code : 12

## 2-) The Stored Procedure That Selects Random Number Between the Two Numbers Entered as Parameters In Sql

In this article we’ll learn the procedure that selects random number between the two numbers entered as parameters.

1 2 3 4 5 6 7 8 |
Create Procedure Sp_Random_Value @first int, @second int, @result int output As Begin Set @result =Floor(RAND() * (@second-@first))+@first End |

After getting succesful message we can run the below code to get random values. You can enter deferent values.

1 2 3 |
Declare @r int Execute Sp_Random_Value 20,30,@r output Select @r |

Each time you run the code, you will receive different values between 20 and 30.

I got the result : 23

1 2 3 |
Declare @r int Execute Sp_Random_Value 20,30,@r output Select @r |

Result : 20

1 2 3 |
Declare @r int Execute Sp_Random_Value 20,30,@r output Select @r |

## 3-) Generate Unique Random Numbers In Sql With Stored Procedure

This procedure generates random unique numbers between two numbers. It gets 3 parameters. The first parameter is number you want to list, the second parameter is the start value and the last parameter is the end value. In this proceure we used table variable. With table variable we saved numbers. We checked if the number exists in the tablei if not exists then the number is added to the table variable

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
Create procedure randomGenerate(@unit int,@min int,@max int) as Begin Declare @numbers table(number int) Declare @i int = 0 Declare @number int while (@i<@unit) Begin Set @number = floor(rand()*(@max-@min+1))+@min if(not exists(Select * from @numbers where number = @number)) begin insert into @numbers values(@number) Set @i = @i + 1 end end Select * from @numbers order by 1 End |

After you run the code above than you run the code below.

1 |
Execute randomGenerate 5,20,30 |

**Result:** Lists 5 numbers between 20 and 30

1 |
Execute randomGenerate 6,0,49 |

**Result:**Lists 6 numbers between 0 and 49

1 |

**Result:**Lists 10 numbers between 50 and 100

## 4-) Calculating Factorial of Given Number with Stored Procedure

In this tutorial we will write “Stored Procedure” calculates the factorial of a number. That is specified at below.

1 2 3 4 5 6 7 8 9 10 |
Create procedure factor(@number int) as begin Declare @i int = 1,@result int=1 while (@i<=@number) Begin Set @result = @result * @i Set @i += 1 End Select @result End |

You must execute the code ebove and get succesful message. Then By running the following code, you can calculate the factorial of the number you want.

1 |
Execute factor 5 |

**Result**:120

1 |
Execute factor 10 |

**Result**:3628800

## 5-) Create A Stored Procedure Calculate Power Of A Number In Sql

In this example we will create a procedure that calculates power of given number.

1 2 3 4 5 6 7 8 9 10 |
Create Procedure myPower(@num int,@pow int, @result int output) As Begin Declare @i int = 0; Set @result = 1 while(@i<@pow) Begin Set @result = @result * @num Set @i += 1 End End |

**The Usage Of The Procedure**

1 2 3 |
Declare @result int Execute myPower 3,4,@result output Select @result |

**Result: 81**

1 2 3 |
Declare @result int Execute myPower 2,5,@result output Select @result |

**Result: 32**

1 2 3 |
Declare @result int Execute myPower 5,3,@result output Select @result |

**Result: 125**

## 6-) Finding The Sum Of The Three Numbers With Stored Procedure

In this tutorial web William create a Procedure that Sums Three numbers. The numbers will be written by parametter. Lets do it.

1 2 3 4 5 6 7 8 |
Create Procedure sumThree @n1 int, @n2 int, @n3 int, @result int output as Begin Set @result = @n1+@n2+@n3 End |

After run the code above we will get successful message. Now we sum any three numbers we want running the code below.

1 |
Execute sumThree 5,7,12 |

**Result**: 24

1 |
Execute sumThree 5,17,12 |

**Result**: 34

## 7) Stored Procedure To Find A Number Is Prime In Sql

We will write a procedure that finds given number is Prime. The procedure gets an integer parameter and a bit parameter output. If the result parameter’s value is 0 (zero) then the written number is prime, if the result parameter’s value is 1 (one) then the written number is non-prime.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
Create Procedure sp_isPrime (@number int,@result bit output) as Begin Set @result = 1 Declare @i int = 2 While (@i<@number) Begin if(@number % @i = 0) Begin Set @result = 0 break End Set @i += 1 End return @result End |

After running the code above we will get succesfull message. Then we can use the procedure like below.

**Example 1**

1 2 3 |
Declare @result bit Execute sp_isPrime 11,@result output Select @result |

**Result**: 1 (Prime)

**Example 2**

1 2 3 |
Declare @result bit Execute sp_isPrime 9,@result output Select @result |

**Result**: 0 (non-Prime)

## 8) Stored Procedure To Divide Numbers And Get Divided Value And Remaining Value

In this post we will write a stored Procedure. We will divide numbers than we will get divided value and remaining value by output parameter.

1 |

After running the code above we will get succesful message, than we may run the codes below

**Ex1**

1 2 3 |
Declare @d int,@r int Execute sp_Devide 34,7,@d output,@r output Select @d Division,@r Remaining |

**Result**

**Ex2**
