MySQL pagination without double-querying?
To work with MySQL pagination, firstly let us see how to use CREATE command and use it to create a table.
mysql>CREATE table RowCountDemo -> ( -> ID int, -> Name varchar(100) -> ); Query OK, 0 rows affected (0.95 sec)
Records are inserted with the help of INSERT command.
mysql>INSERT into RowCountDemo values(1,'Larry'); Query OK, 1 row affected (0.15 sec) mysql>INSERT into RowCountDemo values(2,'John'); Query OK, 1 row affected (0.13 sec) mysql>INSERT into RowCountDemo values(3,'Bela'); Query OK, 1 row affected (0.15 sec) mysql>INSERT into RowCountDemo values(4,'Jack'); Query OK, 1 row affected (0.11 sec) mysql>INSERT into RowCountDemo values(5,'Eric'); Query OK, 1 row affected (0.19 sec) mysql>INSERT into RowCountDemo values(6,'Rami'); Query OK, 1 row affected (0.49 sec) mysql>INSERT into RowCountDemo values(7,'Sam'); Query OK, 1 row affected (0.14 sec) mysql>INSERT into RowCountDemo values(8,'Maike'); Query OK, 1 row affected (0.77 sec) mysql>INSERT into RowCountDemo values(9,'Rocio'); Query OK, 1 row affected (0.13 sec) mysql>INSERT into RowCountDemo values(10,'Gavin'); Query OK, 1 row affected (0.19 sec)
Display all the records with the help of SELECT statement.
mysql>SELECT* from RowCountDemo;
The following is the output.
+------+-------+ | ID | Name | +------+-------+ | 1 | Larry | | 2 | John | | 3 | Bela | | 4 | Jack | | 5 | Eric | | 6 | Rami | | 7 | Sam | | 8 | Maike | | 9 | Rocio | | 10 | Gavin | +------+-------+ 10 rows in set (0.00 sec)
Let us now see the syntax for pagination without double querying.
SELECT column_name From `yourTableName` WHERE someCondition LIMIT value1, value2;
Applying the above syntax now.
mysql> SELECT ID,Name FROM `RowCountDemo` WHERE ID > 0 LIMIT 0, 11;
Here is the output of the above query.
+------+-------+ | ID | Name | +------+-------+ | 1 | Larry | | 2 | John | | 3 | Bela | | 4 | Jack | | 5 | Eric | | 6 | Rami | | 7 | Sam | | 8 | Maike | | 9 | Rocio | | 10 | Gavin | +------+-------+ 10 rows in set (0.00 sec)
