I would like to limit the amount of rows I fetch in MySQL. Can you show me how?
ex:
in mysql you do as follows
SELECT * FROM PERSON_TBL LIMIT 0, 1000
SELECT * FROM PERSON_TBL LIMIT 1000, 1000
Query 1 will fetch first 1000 records,
Query 2 will fetch next 1000 records
Syntax for limits clause
LIMITS OFFSET, ROWCOUNT
Where ROWCOUNT give number of row to fetch
OFFSET gives from which row to fetch more info here
select top x * from table in SQL Server
select * from table where ROWNUM < x in Oracle
select * from table limit x in MySQL
MySQL and PostgreSQL support OFFSET
that is usually used with a LIMIT
clause.
SELECT column FROM table
LIMIT 10000
SELECT column FROM table
LIMIT 10000 OFFSET 10000
TSQL
SELECT TOP 10000
...
PL/SQL
... WHERE ROWNUM < 10000
...
in MySQL :
SELECT * FROM `your_table` LIMIT 0, 10000
This will display the first 10000 results from the database.
SELECT * FROM `your_table` LIMIT 10000, 20000
This will show records 10001, 10002, ... ,20000
The term you're looking for is "pagination." Unfortunately, this is done differently depending on the SQL engine.
For MS SQL Server, see this Stack Overflow question.
Since you mentioned MySQL, it's actually quite simple:
SELECT [columns] FROM [a table] LIMIT 10000
SELECT [columns] FROM [a table] LIMIT 10000 OFFSET 10000
The first statement fetches results 1-10,000, and the second statement fetches results 10,001-20,000.
