_sql_constraints is a list so you can add them like: 

_sql_constraints =[('unique_scheme_id','unique(scheme_id)','Error! scheme Id Already Exist'), ('unique_interval','unique(interval)','Error! Start Day Already Exist'),('unique_interval1','unique(interval1)','Error! End Day Already Exist')]

I'm not sure how your code will perform, either throw an error, or just use the last constraint.

But what you want is easy to achieve:

sql_constraints is a list of tuples: So add all your constraints into one list:

_sql_constraints = [
    ('unique_scheme_id', 'unique(scheme_id)', 'Error! scheme Id Already Exist'),
    ('unique_interval', 'unique(interval)', 'Error! Start Day Already Exist'),
    ('unique_interval1', 'unique(interval1)', 'Error! End Day Already Exist')
]

Note: It might be possible that you want the combination of those three fields to be unique. In that case, use only one unique statement with all fields as argument:

_sql_constraints = [('unique_sheme_type', 'unique(scheme_id,interval,interval1), 'Error! This Type already exists!')]

 

Regards.

Hi, This time only two constraints is taken not excecute 'unique_interval1', 'unique(interval1)', 'Error! End Day Already Exist') this constraints fields

Try this : It will work

_sql_constraints = [('unique_scheme_id','unique(scheme_id)','Error! scheme Id Already Exist'),

                                       ('unique_interval','unique(interval)','Error! Start Day Already Exist')]
