Uses of Join in proper.relaggs

Methods in proper.relaggs with parameters of type Join

void	SqlEngine.addAggregatedAttributes(RelaggsTable dest_table, RelaggsTable source_table, RelaggsStructure struct, Join join) Adds the aggregated attributes to the relaggs table. FracPete: - introduced HashSet to skip duplicate columns and also that there are not too many columns inserted - ADD COLUMN split into single statements (necessary for ANSI SQL!)
java.lang.String	SqlEngine.aggregateAttributes(RelaggsTable main, RelaggsTable aggr, Join join, int number) Combines two tables 'main' and 'aggr' by adding the aggregated columns of table 'aggr' to table main. FracPete: can perform LEFT OUTER JOIN, CREATE TABLE statement now more ANSI compliant
java.sql.PreparedStatement	RelaggsStructure.getUpdateQuery(java.lang.Object key, RelaggsTable source, RelaggsTable dest, Join join) Returns an PreparedStatement containing the UPDATE query with the aggregated values for a key value.
