MonetDB/e, a mature embedded SQL DBMS

We introduce MonetDB/e, our new full-fledged embedded DBMS for data analytics. It encapsulates the full SQL functionality offered by MonetDB, including a rich collection of data types, triggers, schema management, and persistent stored modules.

SQL:1999 grouping combinations now supported in MonetDB

As of MonetDB Jun2020 release, we have added support for ROLLUP, CUBE and GROUPING SETS features defined by the SQL:1999 standard in the GROUP BY clause. These keywords allow one to perform multiple grouping set combinations in a single statement, containing partial and total computed results. At the same time, the GROUPING aggregate, which identifies the grouping columns used in the output, has also been implemented.

SQL:2003 merge statements now supported in MonetDB

As of the Apr2019 release of MonetDB, we have implemented the merge statement feature of the SQL:2003 standard. Merge statements allow one to conditionally insert, update and/or delete records in a target table using an input relation with a single statement.

The grammar is as follows:


     [ WITH with_list ] MERGE INTO table_name [ [AS] ident ] USING input_rel [ [AS] ident ] ON search_condition merge_clause [ merge_clause ]
