In general, this clause is used in conjunction with [ORDER BY](sql-ref-syntax-qry-select-orderby.html) to ensure that the results are deterministic. ### Syntax ```sql LIMIT { ALL | integer_expression } ``` ### Parameters * **ALL** If specified, the query returns all the rows. In other words, no limit is applied if this option is specified. * **integer_expression** Specifies a foldable expression that returns an integer. ### Examples ```sql CREATE TABLE person (name STRING, age INT); INSERT INTO person VALUES ('Zen Hui', 25), ('Anil B', 18), ('Shone S', 16), ('Mike A', 25), ('John A', 18), ('Jack N', 16); -- Select the first two rows. SELECT name, age FROM person ORDER BY name LIMIT 2; +------+---+ | name|age| +------+---+ |Anil B| 18| |Jack N| 16| +------+---+ -- Specifying ALL option on LIMIT returns all the rows. SELECT name, age FROM person ORDER BY name LIMIT ALL; +-------+---+ | name|age| +-------+---+ | Anil B| 18| | Jack N| 16| | John A| 18| | Mike A| 25| |Shone S| 16| |Zen Hui| 25| +-------+---+ -- A function expression as an input to LIMIT. SELECT name, age FROM person ORDER BY name LIMIT length('SPARK'); +-------+---+ | name|age| +-------+---+ | Anil B| 18| | Jack N| 16| | John A| 18| | Mike A| 25| |Shone S| 16| +-------+---+ -- A non-foldable expression as an input to LIMIT is not allowed. SELECT name, age FROM person ORDER BY name LIMIT length(name); org.apache.spark.sql.AnalysisException: The limit expression must evaluate to a constant value ... ``` ### Related Statements * [SELECT Main](sql-ref-syntax-qry-select.html) * [WHERE Clause](sql-ref-syntax-qry-select-where.html) * [GROUP BY Clause](sql-ref-syntax-qry-select-groupby.html) * [HAVING Clause](sql-ref-syntax-qry-select-having.html) * [ORDER BY Clause](sql-ref-syntax-qry-select-orderby.html) * [SORT BY Clause](sql-ref-syntax-qry-select-sortby.html) * [CLUSTER BY Clause](sql-ref-syntax-qry-select-clusterby.html) * [DISTRIBUTE BY Clause](sql-ref-syntax-qry-select-distribute-by.html) * [CASE Clause](sql-ref-syntax-qry-select-case.html) * [PIVOT Clause](sql-ref-syntax-qry-select-pivot.html) * [LATERAL VIEW Clause](sql-ref-syntax-qry-select-lateral-view.html)
