When do we use next(), hasNext() and _next()

[chanikya]

Hi All,

I have 10 records only on whole table , now I want to update records So 

When do we use next(), hasNext() and _next()

[Ankur Bawiskar]

Hi,

since you want to update the records you can use next() method

next() - goes to every record

hasNext() - tells whether there is record satisfying the query

_next() - used when your table field/column name as "name"

Hi Ankur,

at script side, what case we use hasNext();?

[Ankur Bawiskar · Accepted solution]

Hi,

just to check if there is any record satisfying the query

hasNext() - does not actually go to that record but just tells true/false is there is any record matching the query

Hi Ankur, 

Kindly help me for understanding.

if there is an single record in whole table , then can we update that record using with hasNext() in script side.
