Hello ,
I have a program which show reports of students i habe multipile dropdown lists in my page and what the supervisor do is selecting what he wants to show first " for example students who live in usa " /ps i have multi dropdown lists /then my program show him all records in database of these filters .. but my query is not working what i do is
"Select * from students as s where" +"(" + address.length ==0+"||" +address.includes('s.adr') "
Notes ;
Address.length ==0 because i want to all the records in case of the supervisor did not choose country and and wanted all countries in th DB ,,,,
Also note that addres is array containig all the countries that supervisor choose
What i am doing wrong here and how can i vorrect it
Thanksss.
