Golang SelectStatement.RewriteDistinct Examples

Example #1

File: mapper.go Project: harryshayne/bosun

// rewriteSelectStatement performs any necessary query re-writing.
func (lm *SelectMapper) rewriteSelectStatement(stmt *influxql.SelectStatement) (*influxql.SelectStatement, error) {
	var err error
	// Expand regex expressions in the FROM clause.
	sources, err := expandSources(stmt.Sources, lm.shard.index)
	if err != nil {
		return nil, err
	}
	stmt.Sources = sources
	// Expand wildcards in the fields or GROUP BY.
	stmt, err = lm.expandWildcards(stmt)
	if err != nil {
		return nil, err
	}
	stmt.RewriteDistinct()
	return stmt, nil
}

Example #2

File: meta.go Project: eswdd/bosun

// RewriteSelectStatement performs any necessary query re-writing.
func (db *DatabaseIndex) RewriteSelectStatement(stmt *influxql.SelectStatement) (*influxql.SelectStatement, error) {
	// Expand regex expressions in the FROM clause.
	sources, err := db.ExpandSources(stmt.Sources)
	if err != nil {
		return nil, err
	}
	stmt.Sources = sources

	// Expand wildcards in the fields or GROUP BY.
	stmt, err = db.ExpandWildcards(stmt)
	if err != nil {
		return nil, err
	}

	stmt.RewriteDistinct()

	return stmt, nil
}
