Select after first 50 with MYSQL and PHP - mysql

I need to select all the rows AFTER the first 50 rows from a table. I can't seem to figure out an efficient way to do it.
I could select the first 50 rows, put their IDs in an array, then make another query that selects everything except them, but that seems wasteful.
I can't seem to find anything here that does what I need:

Is there anyway to do this in one SQL query? Thanks for the help!

You are probably looking for OFFSET:
For example:
SELECT * FROM users ORDER BY id LIMIT 100 OFFSET 50

You can define an offset:
[LIMIT {[offset,] row_count | row_count OFFSET offset}]
Like this:
SELECT * FROM table1 LIMIT 5, 10; # Retrieve rows 6-15

DELIMITER //
CREATE PROCEDURE displayDataFromGivenRow(IN from_Id INT)
BEGIN
DECLARE row_count INT;
SELECT count(*) INTO row_count
FROM <table_name>;
SELECT *
FROM <table_name>
LIMIT row_count
OFFSET from_Id;
END//
DELIMITER ;
CALL displayDataFromGivenRow(50);
OR
SELECT * FROM table_name LIMIT total_number_of_records OFFSET 50;

Try this
select * from tablename limit 50,100000000
the second argument in limit you can set based on number of row your table may have

FOUND_ROWS() in MariaDB 10

I have a function which needs the number of rows returned by a select. After some googling i found the FOUND_ROWS() function. But i don't think it works:
SELECT * FROM tipfirme LIMIT 20;
SELECT FOUND_ROWS();
because it always returns 1 as the found value.
However, if i run it in one line, it works.
SELECT FOUND_ROWS() FROM (SELECT * FROM tipfirme LIMIT 20) as T
Am i doing something wrong or is the function broken?
FOUND_ROWS returns the number of rows the previous request (entire select statement) returned. It sounds to me like you are wanting just:
select count(1) from (select * From tipfirme limit 20) as T
select found_rows(); separately would not always return 1; I suspect you were not testing what you meant to test. If it immediately follows select * from tipfirme limit 20; it would indeed return the number of rows the select returned (after the limit, or before the limit if you specified sql_calc_found_rows in the previous select).
SELECT FOUND_ROWS() FROM (SELECT * FROM tipfirme LIMIT 20) as T isn't doing what you think; it will return as many rows as the subselect returned, and each will have the number of rows the previously executed select returned, not related to the number of rows from the subselect at all.

How to select rows staring from a row whithout limits?

I want to select rows starting from a row like this:
SELECT * FROM table WHERE Type=1 LIMIT $Start,infinity
If you have a primary key say id, you can use
SELECT * FROM table WHERE Type = 1 AND id >= $Start;
There is nothing to indicate infinity in MySQL. To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter:
SELECT * FROM table WHERE Type=1 LIMIT $Start, 99999999999999999999;

select all the rows from my table except the first 20 rows

I want to select all the rows from my table except the first 20 rows. How it possible? The total number of rows are not static.
SELECT statistics_id,title, user_name FROM (
SELECT statistics_id,title, user_name FROM statistics ORDER BY statistics_id DESC
LIMIT(select count(*)from statistics )-20
) sub
ORDER BY access_statistics_id ASC
I know 'LIMIT(select count(*)from statistics )-20' is not a correct method. Please help.
the documentation says (https://dev.mysql.com/doc/refman/5.5/en/select.html) the following:
To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
so you could use something like
LIMIT 20, veryLargeNumber
Try this
DECLARE v_max bigint unsigned default ~0;
SELECT statistics_id,title, user_name
FROM statistics
LIMIT 20, v_max;
After writing the select query u just have to include,
LIMIT 21,100;
21-Offset i.e from which row you want to start selecting and
100- is the Limit[Which you can set according to your need]
You actually need:
SELECT
statistics_id, title, user_name
FROM statistics
ORDER BY
statistics_id ASC
LIMIT 20, 18446744073709551615;
As per MySQL Documentation
To retrieve all rows from a certain offset up to the end of the result
set, you can use some large number for the second parameter. This
statement retrieves all rows from the 96th row to the last:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
If your table grows fast, selecting all rows (with exception of first 20) is not a good idea. In such case, you should batch your query, and handle a subset of entries at a time, some thing like:
SELECT * FROM tbl LIMIT 20,120;
Try using the offset option for the LIMIT syntax. you can read more about the LIMIT syntax at http://dev.mysql.com/doc/refman/5.0/en/select.html.
SELECT `statistics_id`
, `title`
, `user_name`
FROM `statistics`
ORDER BY `statistics_id` ASC
LIMIT 20, 18446744073709551615

how to specify only start index in LIMIT in MySQL select query?

I want to select the records from the table starting from 3rd row. How this can achieved with LIMIT?
From the MySQL Documentation:
To retrieve all rows from a certain offset up to the end of the
result set, you can use some large number for the second parameter.
This statement retrieves all rows from the 96th row to the last:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
Like this:
SELECT * FROM MyTable LIMIT 2, 18446744073709551615;
(The offset is zero-based)
i am giving syntax
SELECT field1, field2,...fieldN table_name1, table_name2...
[WHERE Clause]
[OFFSET M ][LIMIT N]

Omit the first 5 rows?

I want to SELECT all rows except for the first 5 rows in a table.
How do I do that?
Why can't I just type
$query = "SELECT *
FROM ages
OFFSET 5
ORDER BY id ASC";
SELECT * FROM tbl LIMIT 5,18446744073709551615;
from http://dev.mysql.com/doc/refman/5.0/en/select.html
To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:
SELECT * FROM tbl LIMIT 95,18446744073709551615;
In Oracle:
select name, price
from items
where rownum > 5
Here's a solution using variables - just add your order by clause and you should be set.
set #n=-1
select * from TABLE where (#n:=#n+1) >= 5;
I just typed:
$query = "SELECT *
FROM ages
LIMIT 100
OFFSET 10";
Why couldn't anybody give me such an easy answer? :)
