Must declare the scalar variable? Microsoft SQL Server

Question

This code is throwing an error:

Must declare scalar variable @MANDATORY"

Code:

CREATE PROCEDURE [dbo].[CRE_STATION_PR]
    @P_CODE VARCHAR(10),
    @P_NAME VARCHAR(50),
    @P_COORDINATE_X FLOAT,
    @P_COORDINATE_Y FLOAT,
    @P_LOCATION VARCHAR(50),
    @P_STATE_PURPOSE VARCHAR(200),
    @P_MANDATORY BIT,
    @P_ID_STATE INT
AS
    INSERT INTO TBL_STATIONS (CODE, NAME, COORDINATE_X, COORDINATE_Y, LOCATION, STATE_PURPOSE, MANDATORY, ID_STATE) 
    VALUES (@P_CODE, @P_NAME, @P_COORDINATE_X, @P_COORDINATE_Y, @P_LOCATION, @P_STATE_PURPOSE, @MANDATORY, @P_ID_STATE)

    RETURN 0
GO

What should I do?

Answer 1

There is a typo in your insert query

INSERT INTO TBL_STATIONS 
(CODE,NAME,COORDINATE_X,COORDINATE_Y,LOCATION,STATE_PURPOSE,MANDATORY,ID_STATE) 
VALUES 
(@P_CODE,@P_NAME,@P_COORDINATE_X,@P_COORDINATE_Y,@P_LOCATION,@P_STATE_PURPOSE,
@P_MANDATORY, --Here P_ missing 
@P_ID_STATE)
