Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

MySQL Overview#

The MySQL application on Pipedream enables direct interaction with your MySQL databases, allowing you to perform CRUD operations—create, read, update, delete—on your data with ease. You can leverage these capabilities to automate data synchronization, report generation, and event-based triggers that kick off workflows in other apps. With Pipedream's serverless platform, you can connect MySQL to hundreds of other services without managing infrastructure, crafting complex code, or handling authentication.

Trigger Code#

import common from "../common/table.mjs";

export default {
  ...common,
  key: "mysql-new-column",
  name: "New Column",
  description: "Emit new event when you add a new column to a table. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/show-columns.html)",
  type: "source",
  version: "2.0.5",
  dedupe: "unique",
  props: {
    ...common.props,
    db: "$.service.db",
  },
  methods: {
    ...common.methods,
    _getPreviousColumns() {
      return this.db.get("previousColumns");
    },
    _setPreviousColumns(previousColumns) {
      this.db.set("previousColumns", previousColumns);
    },
    async listResults() {
      const { table } = this;
      let previousColumns = this._getPreviousColumns() || [];
      const columns = await this.mysql.listNewColumns({
        table,
        previousColumns,
      });
      this.iterateAndEmitEvents(columns);

      const newColumnNames =
        columns
          .map((column) => column.Field)
          .filter((c) => !previousColumns.includes(c));

      previousColumns = previousColumns.concat(newColumnNames);
      this._setPreviousColumns(previousColumns);
    },
    generateMeta(column) {
      const columnName = column.Field;
      return {
        id: `${columnName}${this.table}`,
        summary: columnName,
        ts: Date.now(),
      };
    },
  },
};

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
MySQL	`mysql`	`app`	This component uses the MySQL app.
	`timer`	`$.interface.timer`
Table	`table`	`string`	Select a value from the drop down menu.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.

Trigger Authentication#

MySQL uses API keys for authentication. When you connect your MySQL account, Pipedream securely stores the keys so you can easily authenticate to MySQL APIs in both code and no-code steps.

Connecting to Restricted Databases

Either enable the shared static IP for this account below, or configure a VPC to deploy any workflow in your workspace to a private network with a dedicated static IP. Learn more in our docs.

SSL Setup

Configure SSL on your MySQL database by providing the CA (Certificate Authority), and choosing between Full Verification, Verify Certificate Authority (CA), or Skip Verification. Skipping verification is not recommended as this has serious security implications.

About MySQL#

MySQL is an open-source relational database management system.
