Hi All,
I know the basics of SQl and can write simple SQL queries, But whenever i have to write any complex Queries or scenarios type Queries , I cannot write it.
I have been rejected from many Interviews in the first round just because of Sql Queries. From my Side I try to practise on Oracle dev on emp and dept tables., Google oracle complex queries, and see the issues in different communities and groups. I do understand them and their logic , but when start writing myself ,i become blank.
Kindly Guide me to follow proper approach..
