Recently, I'm reading a book about SQL.
In that book, I can't understand this term - Ad Hoc Query.
I want to know what is exactly means "Ad Hoc Query"
Help me, plz.
Thanks in advance.
I'm reading a book about SQL.
In that book, I saw strange query below:
"SELECT * into mycustomer from customer WHERE 1=2"
In this query, what is "WHERE 1=2" ?
Thanks in advance.
