SQLPage v0.17.1 documentation
If you are completely new to SQLPage, you should start by reading the get started tutorial, which will guide you through the process of creating your first SQLPage application.
Building an application with SQLPage is quite simple. To create a new web page, just create a new SQL file. For each SELECT statement that you write, the data it returns will be analyzed and rendered to the user. The two most important concepts in SQLPage are components and parameters.
- components are small user interface elements that you can use to display your data in a certain way.
- top-level parameters are the properties of these components, allowing you to customize their appearance and behavior.
- row-level parameters constitute the data that you want to display in the components.
To select a component and set its top-level properties, you write the following SQL statement:
SELECT 'component_name' AS component, 'my value' AS top_level_parameter_1;
Then, you can set its row-level parameters by writing a second SELECT statement:
SELECT my_column_1 AS row_level_parameter_1, my_column_2 AS row_level_parameter_2 FROM my_table;
This page documents all the components provided by default in SQLPage and their parameters. Use this as a reference when building your SQL application. If at any point you need help, you can ask for it on the SQLPage forum.
The "cookie" component
Sets a cookie in the client browser, used for session management and storing user-related information. This component creates a single cookie. Since cookies need to be set before the response body is sent to the client, this component should be placed at the top of the page, before any other components that generate output. After being set, a cookie can be accessed anywhere in your SQL code using the `sqlpage.cookie('cookie_name')` pseudo-function.
Create a cookie named
username with the value
SELECT 'cookie' as component, 'username' as name, 'John Doe' as value FALSE AS secure; -- You can remove this if the site is served over HTTPS.
and then display the value of the cookie using the
SELECT 'text' as component, 'Your name is ' || COALESCE(sqlpage.cookie('username'), 'not known to us');
