jQuery Datatables and Laravel 6.x Pagination

May 17, 2020May 17, 2020 odenktools Leave a comment

jQuery DataTables is a table component that is powerful for data management. These plugins provide searching, sorting, pagination, filter per column, and many more. But we have some problems combining jQuery Datatables and Laravel framework.

We separate applications (Rest API and User Interface). For Rest API we use Laravel Framework and for User Interface use Laravel too, but we only Blade component and Guzzle as HTTP Client Library.

We now Laravel has good packages for handle it, as far I know Yajra’s good and incredible packages (you can see Yajra’s package on Github). But using Yajra’s library was not possible at that time, because Yajra was using Eloquent and can’t use HTTP Client (like Guzzle, UniRest, etc). Then we do research to deal with this problem and got results as we would discuss in this post.

On these tutorials, we use an empty Laravel 6.x project with Bootstrap 3, jQuery Datatables plugins. Our goal in this tutorial is to Display User Lists in Datatables (Searching and Sorting also). Ok let’s start the codings. Read More

Dynamic Crosstab With Store Procedure

October 29, 2015October 29, 2015 odenktools 3 Comments

Let’s assume that we have table with data like this bellow :

and we want to view data like this

for that we can write query like this

SELECT 
   SUM(IF(category='1991', value, 0)) as '1991',
   SUM(IF(category='1992', value, 0)) as '1992',
   SUM(IF(category='1993', value, 0)) as '1993' 
FROM dynamic_crosstab;

SELECT

SUM(IF(category='1991', value, 0)) as '1991',

SUM(IF(category='1992', value, 0)) as '1992',

SUM(IF(category='1993', value, 0)) as '1993'

FROM dynamic_crosstab;

But, what we can do if the data going bigger and category added, e.g. 1995, 1996. Yes of course we can add

SUM(IF(category='1993', value, 0)) as '1995'

1	SUM(IF(category='1993', value, 0)) as '1995'

once again but, how if we have many category value which are similary. i think this is a waste, so ot will usefull if we write crosstab dynamicly. let’s check it out

CREATE DEFINER = 'root'@'localhost'
PROCEDURE usefull.dynamic_crosstab()
BEGIN
    SELECT GROUP_CONCAT( DISTINCT CONCAT("SUM( IF( category ='", category,"', value ,0 )) as '", category, "'")) FROM dynamic_crosstab into @crosstab_column;
    
    set @query  = concat("SELECT ", @crosstab_column, " FROM dynamic_crosstab");
     prepare  stmt FROM @query;
     execute  stmt;

END

CREATE DEFINER = 'root'@'localhost'

PROCEDURE usefull.dynamic_crosstab()

BEGIN

SELECT GROUP_CONCAT( DISTINCT CONCAT("SUM( IF( category ='", category,"', value ,0 )) as '", category, "'")) FROM dynamic_crosstab into @crosstab_column;

set @query = concat("SELECT ", @crosstab_column, " FROM dynamic_crosstab");

prepare stmt FROM @query;

execute stmt;

END

the query above will transform all category value into column, wich distinct will prevent the redundance. just keep in mind and hope this helpfull.
