func (Parser) ParseTemplate ¶
ParseTemplate build an export template by parsing a query string. Selected fields must be all primary keys, one for each joined table, potentially more than one per table (multiple joins, note that composite keys are unsupported). Selected fields must be like "SELECT alias.pk as alias". If provided, ORDER BY must specify primary keys only, at most once per key (per join), and only in ascending order. An arbitrary WHERE may be provided, which will be combined (using AND) into the batch select.
