Gmail

The Gmail component uses the Gmail API to retrieve data to load into a table—this stages the data, so the table is reloaded each time. You can then use transformations to enrich and manage the data in permanent tables.

Warning

This component is potentially destructive. Depending on the setting of the property Create Table Mode, the target table might be recreated or truncated. Setting the property to Fail if Exists will prevent both recreation and truncation. Do not modify the target table structure manually.


Properties

Name = string

A human-readable name for the component.


Authentication Type = drop-down

Select OAuth 2.0 Authorization Code from the drop-down menu.


Auth Secret = drop-down

Choose your profile from the drop-down menu. To create your own OAuth connection, use the following steps:

  1. Click Manage in the Auth Secret dialog.
  2. Click Add OAuth connection in the OAuth tab to open Add new OAuth.
  3. Give an appropriate OAuth name.
  4. Use the drop-down menu to select the Google provider.
  5. Select OAuth 2.0 Authorization Code Grant from the Authentication type drop-down.
  6. Click Sign in with Google.
  7. Choose an account.
  8. Click Allow to authorize Matillion Data Productivity Cloud access to your chosen Google account. You will return to the OAuth tab, where your new OAuth connection will have been created.

Connection Options = column editor

  • Parameter: A JDBC parameter supported by the database driver. The available parameters are explained in the data model. Manual setup is not usually required, since sensible defaults are assumed.
  • Value: A value for the given parameter.

Click the Text Mode toggle at the bottom of the Connection Options dialog to open a multi-line editor that lets you add items in a single block. For more information, read Text mode.


Mode = drop-down

  • Basic: This mode will build a query for you using settings from the Schema, Data Source, Data Selection, Data Source Filter, Combine Filters, and Limit parameters. In most cases, this mode will be sufficient.
  • Advanced: This mode will require you to write an SQL-like query to call data from Gmail. The available fields and their descriptions are documented in the data model.

There are some special pseudo columns that can form part of a query filter, but are not returned as data. This is fully described in the data model.

Note

While the query is exposed in an SQL-like language, the exact semantics can be surprising, for example, filtering on a column can return more data than not filtering on it. This is an impossible scenario with regular SQL.


SQL Query = code editor

This is an SQL-like SELECT query. Treat collections as table names, and fields as columns. Only available in Advanced mode.


Data Source = drop-down

Select a data source.


Data Selection = dual listbox

Choose one or more columns to return from the query. The columns available are dependent upon the data source selected. Move columns left-to-right to include in the query.

To use grid variables, tick the Use Grid Variable check box at the bottom of the Data Selection dialog.


Data Source Filter = column editor

  • Column: Select an input column. The available input columns vary depending upon the data source.
  • Qualifier:
    • Is: Compares the column to the value using the comparator.
    • Not: Reverses the effect of the comparison, so "Equals" becomes "Not equals", "Less than" becomes "Greater than or equal to", etc.
  • Comparator: Choose a method of comparing the column to the value. Possible comparators include: "Equal to", "Greater than", "Less than", "Greater than or equal to", "Less than or equal to", "Like", "Null". "Equal to" can match exact strings and numeric values, while other comparators, such as "Greater than" and "Less than", will work only with numerics. The "Like" operator allows the wildcard character % to be used at the start and end of a string value to match a column. The Null operator matches only null values, ignoring whatever the value is set to. Not all data sources support all comparators, meaning that it is likely that only a subset of the above comparators will be available to choose from.
  • Value: The value to be compared.

Click the Text Mode toggle at the bottom of the Connection Options dialog to open a multi-line editor that lets you add items in a single block. For more information, read Text mode.
