Question

I have a query in SQL where I need to add a condition, to find all the records that have an empty field.

This gave me an error..

SELECT forma.*, SMS_MONTIME.IDTICKET, SMS_MONTIME.MBYLLUR,SMS_MONTIME.time_added
FROM forma 
LEFT JOIN SMS_MONTIME ON forma.ID = SMS_MONTIME.IDTICKET WHERE SMS_MONTIME.IDTICKET ==''

Thanks

Answer 1

In query use just = for checking not == and for checking null values use is null

SELECT forma.*, SMS_MONTIME.IDTICKET, SMS_MONTIME.MBYLLUR,SMS_MONTIME.time_added
FROM forma 
LEFT JOIN SMS_MONTIME ON forma.ID = SMS_MONTIME.IDTICKET WHERE SMS_MONTIME.IDTICKET ='' or SMS_MONTIME.IDTICKET is null
