This property enhances SQL functionality beyond what can be supported through the API directly, by enabling in-memory client-side processing.

Syntax

Connect-GAds -SupportEnhancedSQL SwitchParameter

Data Type

bool

Default Value

false

Remarks

When SupportEnhancedSQL = true, the cmdlet offloads as much of the SELECT statement processing as possible to Google Ads and then processes the rest of the query in memory. In this way, the cmdlet can execute unsupported predicates, joins, and aggregation.

When SupportEnhancedSQL = false, the cmdlet limits SQL execution to what is supported by the Google Ads API.

Execution of Predicates

The cmdlet determines which of the clauses are supported by the data source and then pushes them to the source to get the smallest superset of rows that would satisfy the query. It then filters the rest of the rows locally. The filter operation is streamed, which enables the cmdlet to filter effectively for even very large datasets.

Execution of Joins

The cmdlet uses various techniques to join in memory. The cmdlet trades off memory utilization against the requirement of reading the same table more than once.

Execution of Aggregates

The cmdlet retrieves all rows necessary to process the aggregation in memory.
