How to query n records in mysql oracle sqlserver

SELECT * FROM table LIMIT 5;

Select * from issu_info limit 0, 6

Limit 0, 6

This is correct. The first six items are displayed.

Select * from issu_info limit 7, 6;

Limit 7, 6

Take from 8th, take 6

Select * from table order by rand () limit 1

This is to randomly select a record. If you want to extract multiple records, change 1 to the number you want to Top.

Using a feature of the select statement in mysql, you can easily implement paging of query results. The syntax of the select statement is as follows:

SELECT [STRAIGHT_JOIN] [SQL _SMALL_RESULT] [SQL _BIG_RESULT] [HIGH_PRIORITY]

[DISTINCT | DISTINCTROW | ALL]

Select_expression ,...

[Into outfile 'file _ name' export_options]

[FROM table_references

[WHERE where_definition]

[Group by col_name,…]

[HAVING where_definition]

[Order by {unsigned_integer | col_name | formula} [ASC | DESC],…]

[LIMIT [offset,] rows]

[PROCEDURE procedure_name]

The LIMIT clause can be used to LIMIT the number of data returned by the SELECT statement. It has one or two parameters. If two parameters are provided,

The first parameter specifies the position of the first row returned in all data, starting from 0 (note not 1). The second parameter specifies the maximum number of returned rows.

Number. For example:

Select * from table LIMIT 5, 10; # return data in rows 6-15

Select * from table LIMIT 5; # Return the first five rows

Select * from table LIMIT; # Return the first five rows

SQL statements used to query the first few records in different databases: 261. ORACLE

SELECT * FROM TABLE1 where rownum <= N

2. INFORMIX

Select first n * FROM TABLE1

3. DB2

SELECT * ROW_NUMBER () OVER (order by COL1 DESC) as rownum where rownum <= N

Or

SELECT COLUMN FROM TABLE FETCH FIRST N ROWS ONLY

4. SQL SERVER

Select top n * FROM TABLE1

5. SYBASE

SET ROWCOUNT N

GO

SELECT * FROM TABLE1

6. MYSQL

SELECT * FROM TABLE1 LIMIT N

7. FOXPRO

SELECT * TOP N FROM TABLE ORDER BY COLUMN

8. query the first few SQL records in postgres

SELECT * FROM TABLE LIMIT

Select id from mytable order by update_date desc limit 0, 3;
