Connect to databases, execute queries, and manipulate data in Concrete CMS projects. Use this skill when the user asks to build custom block types or connect with database.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Working with Database

## How to connect

Use `$db = $this->app->make(\Concrete\Core\Database\Connection\Connection::class);` Do not use the `Database` facade, it is deprecated.

## XML file format for database schemas

Concrete CMS uses "Doctrine XML" file format to define database schema. Ref: https://concretecms.github.io/doctrine-xml/doctrine-xml-0.5.xsd

Here's an example with all the features offered by Doctrine XML:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.concrete5.org/doctrine-xml/0.5"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.concrete5.org/doctrine-xml/0.5
    https://concretecms.github.io/doctrine-xml/doctrine-xml-0.5.xsd"
>

    <table name="Companies" comment="List of companies">
        <field name="Id" type="integer" comment="Record identifier">
            <unsigned/>
            <autoincrement/>
            <key/>
        </field>
        <field name="Name" type="string" size="50" comment="Company name">
            <notnull/>
            <opt for="mysql" collation="utf8_bin"/>
        </field>

How to install

The exact contents, by fingerprint

mdr add macareuxdigital/concretecms-skills/working-with-database@sha256:aff79813911ccb94

The line at the top of this page pins the label git:20260913.db96265, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
