Here when criteria get satisfied.
Those records get selected...
So i think option 2 is right....

The given answer is correct. Don't get confused. The questions is asked about only about *, not about whether the corresponding select query has any Where condition or any other limitations.

In SQL, we can use the asterik mark(*) to retrive all the table data instead of giving all attribute names in the Query!

Can anyone explain what is SQL-92 Standard?

Sql-92 was the third edition of SQL database query language. The later version of SQL is,

> SQL-99, SQL-2003, SQL-2008, SQL-2011.

And * means it will return all column of a table whether all record meets full criteria or not.

Anil said: (Mar 20, 2017)  
Here, * means select all

Some are saying option 2 is right with the following example.


Here when criteria get satisfied.

Those records get selected.
So option 2 is right.
BUT let me clear them this query will also return all columns of table with age 19.
And second option is about records NOT columns.
