A SELECT statement in SQL returns a result set of records from one of more tables.

Examples

Select C1 from T

C1	C2
1	a
2	b

Select * from T where C1=1

C1	C2

Given a table T, the query Select * from T will result in all the elements of all the rows of the table being shown.

With the same table, the query Select C1 from T will result in the elements from the column C1 of all the rows of the table being shown.

With the same table, the query Select * from T where C1=1 will result in all the elements of all the rows where the value of column C1 is '1' being shown.
