This is my code but it doesn't work for me


SELECT ABS(DATEDIFF(FECHA, LAG(FECHA) OVER (ORDER BY FECHA))) FROM `Clientes`;
WHERE `Clientes`.`ID`='%ID%'

SELECT DATEDIFF( ( SELECT MIN(FECHA) FROM Clientes WHERE FECHA > ( SELECT FECHA FROM Clientes WHERE `Clientes`.`ID`='%ID%' ) ), ( SELECT FECHA FROM Clientes WHERE `Clientes`.`ID`='%ID%' ) ) AS date_diff FROM Clientes WHERE `Clientes`.`ID`='%ID%';
