SQL TOP, LIMIT, FETCH FIRST or ROWNUM Clause
The SQL SELECT TOP Clause
The SELECT TOP clause is used to specify the number of records to return.
The SELECT TOP clause is useful on large tables with thousands of
records. Returning a large number of records can impact performance.
Example
Select only the first 3 records of the Customers table:
SELECT TOP 3 * FROM Customers;

Note: Not all database systems support the
SELECT TOP clause. MySQL
supports the LIMIT clause to select a limited number of records, while Oracle uses
FETCH FIRST n ROWS ONLY and ROWNUM.
SQL Server / MS Access Syntax:
SELECT TOP number|percent column_name(s)
FROM table_name
WHERE condition;
MySQL Syntax:
SELECT column_name(s)
FROM table_name
WHERE condition
LIMIT number;
Oracle 12 Syntax:
SELECT column_name(s)
FROM table_name
ORDER BY
column_name(s)
FETCH FIRST number ROWS ONLY;
Older Oracle Syntax:
SELECT column_name(s)
FROM table_name
WHERE ROWNUM <= number;
Older Oracle Syntax (with ORDER BY):
SELECT *
FROM (SELECT column_name(s) FROM table_name
ORDER BY column_name(s))
WHERE ROWNUM <= number;
