SELECT - Limiting results

Syntax

Below is the syntax for this command. Text within square brackets (i.e, [ and ] ) are optional. Choices are separated by bars (i.e, | ). Ellipses preceded by a comma indicates a repeating pattern. Ellipses before or after syntax are used to highlight a relevant except from the larger syntax. Text displayed in italic letters represent text that should be replaced with the specific names related to the database (e.g., column with the name of the column).

 SELECT [flags] {*|column|expression}[, ...]
FROM table[, ...]
[WHERE condition]
[other clauses]
[LIMIT {[offset,] count|count OFFSET offset}]
[PROCEDURE procedure(arguments)]
[FOR UPDATE|LOCK IN SHARE MODE]]
[other clauses] [options]

Explanation

The LIMIT clause is used to limit the number of rows displayed by the SELECT statement. The most straightforward method of limiting the number of rows is to specify the maximum row count to be displayed

Examples

SELECT * FROM employeesLIMIT 5;

To begin listing rows after a specific number of records, an offset may be given. The offset for the first row is 0. Two formats accomplish this. One gives the amount of the offset, followed by a comma and then the maximum count of rows to display. The other syntax structure specifies the count followed by the OFFSET keyword, followed by the amount of the offset. Here is an example of the first structure, which is preferred:

SELECT * FROM employeesLIMIT 10, 5;

In this example, after the 10th record is reached, the next 5 records will be displayed—in other words, results 11 through 15 are returned. The offset and count for the LIMIT clause are based on the rows in the results set, not necessarily on the rows in the tables. So the amount of the offset is related to the order of the rows retrieved from the tables based on clauses, such as the WHERE clause and the ORDER BY clause. See the description of the LIMIT clause for more details.
