MySQL Database Actions

Note: Database Action tags are expected to follow the format: databaseTag:dbActionTag. This convention ensures clarity and prevents conflicts across different databases and their actions.

Action Type	SQL Query Type
Read	SELECT
Create	INSERT
Update	UPDATE
Delete	DELETE
Aggregate	SELECT (for aggregations)

Data Validation

To define data validation for each datapoint you can follow the pattern

'{{key:type:minlength:maxlength}}'

All fields asides the key are optional

e.g

'{{key}}' is valid

When the non key values are not defined

The default values are

• type - (string)
• minlength - (1) one
• maxlength - (0) unlimited

Creating MySQL Database Actions

Create Operation

const data: IProductDatabaseAction = {
  tag: 'mysql-db-tag:create-user',
  tableName: 'users',
  type: DatabaseActionTypes.CREATE,
  template: `
    INSERT INTO users (username, firstname, lastname, date_of_birth, address, occupation)
    VALUES ('{{username:${DataTypes.NOSPACES_STRING}:3:20}}', '{{firstname:${DataTypes.STRING}}}', '{{lastname}}', '{{dateOfBirth}}', '{{address}}', '{{occupation}}')
  `
};

const action = await ductape.product.databases.actions.create(data);

Read Operation

const data: IProductDatabaseAction = {
  tag: 'mysql-db-tag:read-user',
  tableName: 'users',
  type: DatabaseActionTypes.READ,
  template: `
    SELECT * FROM users WHERE username = '{{username}}'
  `
};

const action = await ductape.product.databases.actions.create(data);

Update Operation

const data: IProductDatabaseAction = {
  tag: 'mysql-db-tag:update-user',
  tableName: 'users',
  type: DatabaseActionTypes.UPDATE,
  template: `
    UPDATE users
    SET firstname = '{{firstname}}', lastname = '{{lastname}}', address = '{{address}}'
    WHERE username = '{{username}}'
  `
};

const action = await ductape.product.databases.actions.create(data);

Delete Operation

const data: IProductDatabaseAction = {
  tag: 'mysql-db-tag:delete-user',
  tableName: 'users',
  type: DatabaseActionTypes.DELETE,
  template: `
    DELETE FROM users WHERE username = '{{username}}'
  `
};

const action = await ductape.product.databases.actions.create(data);
