Google Ads Query

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

If the component requires access to a cloud provider, it will use credentials as follows:

  • If using Matillion Full SaaS: The component will use the cloud credentials associated with your environment to access resources.
  • If using Hybrid SaaS: By default the component will inherit the agent's execution role (service account role). However, if there are cloud credentials associated to your environment, these will overwrite the role.

Warning

This component is potentially destructive. If the target table undergoes a change in structure, it will be recreated. Otherwise, the target table is truncated. Setting the load option Recreate Target Table to Off will prevent both recreation and truncation. Do not modify the target table structure manually.

Properties

Reference material is provided below for the Connect, Configure, Destination, and Advanced Settings properties.

Connect

Authentication = drop-down

Opens a dialog to select an OAuth connection. Click Manage to navigate to the OAuth tab to review OAuth connections and to add new connections. Read Google Query authentication guide to learn how to create an OAuth connection.

Client Customer ID = string

Your unique Google Ads customer ID. If you need to add multiple client customer IDs, separate them using a comma-delimited list. Read Find your Google Ads customer ID to learn how to locate this ID.

Connection Options = column editor

  • Parameter: A JDBC parameter supported by the database driver. The available parameters are explained in 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.

Configure

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 the service you're connecting to. 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 checkbox at the bottom of the Data Selection dialog.

Data Source Filter = column editor

  • Input 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.

Combine Filters = drop-down

Select whether to use the defined filters in combination with one another according to either And or Or.

Use Accelerated Endpoint = boolean

When True, data will be loaded via the s3-accelerate endpoint. Consider the following information:

  • Enabling acceleration can enhance the speed at which data is transferred to the chosen S3 bucket. However, enhanced speed is not always guaranteed. Read Amazon S3 Transfer Acceleration Speed Comparison to compare S3 Direct versus S3 Accelerated Transfer speeds.
  • Users must manually set the acceleration configuration of an existing bucket. To learn more, read PutBucketAccelerateConfiguration in the AWS API Reference.
  • This property is only available if the selected S3 bucket has Amazon S3 Transfer Acceleration enabled. For more information, including how to enable this feature, read Getting started with Amazon S3 Transfer Acceleration.
  • Cases may arise where Data Productivity Cloud can't determine whether the chosen S3 bucket has Amazon S3 Transfer Acceleration enabled. In these cases, Designer will reveal this property for user input on a "just in case" basis. In these cases, Designer may return a validation message that reads "OK - Bucket could not be validated." You may also encounter cases where, if you do not have permission to get the status of the acceleration configuration (namely, the permission, GetAccelerateConfiguration), Designer will again show this property "just in case".
  • The default setting is False.
