Introduction
The Report Search Datalist Binder plugin is Plugin is a Datalist Binder that enables data aggregation and data pivoting on a raw data using SQL queries. This plugin is best paired with EChart Userview Menu Plugin.
Lets understand little bit about data aggregation and data pivoting.

Pivoting refers to the process of transforming rows into columns or, more generally, reorganizing data from a long format to a wide format. It is typically used when you have data that needs to be presented in a different structure. For example, if you have a table with dates, categories, and values, and you want to turn the categories into columns, you would pivot the data. Please refer to https://learn.microsoft.com/en-us/sql/t-sql/queries/from-using-pivot-and-unpivot?view=sql-server-ver16 to read more on pivoting. |

Aggregating involves performing a calculation on a set of values to return a single summary value. Common aggregate functions in MySQL include SUM, COUNT, AVG, MAX, and MIN. Aggregates are used to summarize or extract information from a dataset, such as finding the total, average, or maximum value in a column. Aggregates are typically used in conjunction with the GROUP BY clause to perform calculations on groups of rows based on a common attribute. Please refer to https://www.simplilearn.com/tutorials/sql-tutorial/sql-aggregate-functions to read more on the aggregation. |

| SQL SELECT Query * |
This SQL SELECT Query is meant to select/query the raw data. Aggregation and Pivot will be applied to this raw data. You can also specify the columns name instead of *.
|
|
|
|
|
|
Sample: SELECT * FROM dir_user
|
| SQL Select Query (Data) * | This |
SQL Select Query (Data) |
Sample: SELECT locale, active, COUNT(active) as `count` FROM #data# GROUP BY active, locale
is the aggregated query to group and summarize the raw data from the SQL SELECT Query above.
Take note here that #data# place holder is used to inject the SQL SELECT Query which queries the raw data. Here we are selecting c_category as name, c_year, c_type, sum(c_amount) columns. We are using aggregate function SUM(). GROUP BY is used to group the to group the rows with the same values in columns specified in SELECT statement.
| ||||||||||||
| Primary Key * | Primary key to uniquely identify each row of the table. In here we are using name (c_name) as primary key as GROUP BY will be applied to c_name column. | |||||||||||
| Pivot Data | When this option is checked, plugin will perform pivoting on the data.
| |||||||||||
| Pivot Column Name * | Refers to selecting the field or column in your dataset that you want to use as a basis for creating columns or headers in the pivot table. |
Multiple columns supported. Separate multiple columns using semicolon. (e.g. year;customer) | |
| Pivot Value Column Name * | Refers to the field or column in your dataset that contains the data you want to summarize or aggregate in your pivot table. Multiple columns supported. Separate multiple columns using semicolon. (e.g. outstanding;paid) |
| Value to Fill Up Empty Cell |
The value to fill up if there is an empty cell. E.g. 0.00 |
Plugin Usage
1. Create a datalist and attach this plugin as source of data at "Select Data Store".
Figure 6: List Builder Select Data Store
2. Fill in the plugin configurations as shown in Figure 4.
3. If everything is filled appropriately, you can preview the pivot table.
Figure 7: List Builder Preview
4. Create an UI using UI Builder. You can pair this plugin with EChart Userview Menu Plugin to dynamically change the chart value and shape based on the datalist value. "Show Filters" must be enabled so that you can dynamically change the chart display parameters. Under "Data Mappings", attach the List created previously.
Figure 8: UI Builder
5. Save and return to the front end UI. We can see the List attached with the EChart. Below shows that filter is not used.
Figure 9: Pivot table with EChart without filter
6. 2021 is entered at "year" filter. You can see that the datalist dynamically changed based on the filter. The EChart's value was also updated based on the modified datalist.
