func Query ¶

This is used for chaining to provide access to MicroDB specific API through a conventitional builder interface.
func (*QueryStmt) GetDestinationTable ¶
GetDestinationTable returns the destination table.
This is only used for INSERT queries.
func (*QueryStmt) GetDestinationType ¶
func (q *QueryStmt) GetDestinationType() DestinationType
GetDestinationType returns the destination.
func (*QueryStmt) GetQueryType ¶
GetQueryType returns the query type.
func (*QueryStmt) GetRequiredTables ¶
GetRequiredTables returns all the tables required by the query.
func (*QueryStmt) OnLocal ¶
OnLocal forces the query to the local database.
This could be overrided at query-time if the query contains tables that do not exist locally.
