Same name and namespace in other branches

1. 8 core/modules/views/src/Plugin/views/query/Sql.php \Drupal\views\Plugin\views\query\Sql::addWhereExpression()

Add a complex WHERE clause to the query.

The caller is responsible for ensuring that all fields are fully qualified (TABLE.FIELD) and that the table already exists in the query. Internally the dbtng method "where" is used.

Parameters

$group: The WHERE group to add these to; groups are used to create AND/OR sections. Groups cannot be nested. Use 0 as the default group. If the group does not yet exist it will be created as an AND group.

$snippet: The snippet to check. This can be either a column or a complex expression like "UPPER(table.field) = 'value'"

$args: An associative array of arguments.
