macro class fromQuery extends Annotation with StaticAnnotation

Macro annotation for a BigQuery SELECT query.

Generate case classes for a BigQuery SELECT query. Note that query must be a string literal of the SELECT query with optional .stripMargin at the end. For example:

@BigQueryType.fromQuery("SELECT field1, field2 FROM [project:dataset.table]")

String formatting syntax can be used in query when additional args are supplied. For example:

@BigQueryType.fromQuery("SELECT field1, field2 FROM [%s]", "table")

"$LATEST" can be used as a placeholder for table partitions. The latest common partition available for all tables with the placeholder will be used. For example:

@BigQueryType.fromQuery(
  "SELECT field1, field2 FROM [project:d1.t1_%s] JOIN [project:d2.t2_%s] USING field3",
  "$LATEST", "$LATEST")

Also generate a companion object with convenience methods.

Both Legacy SQL and Standard SQL dialects are supported. By default the query dialect will be automatically detected. To override this behavior, start the query string with #legacysql or #standardsql.
