annotate src/main/java/nl/cwi/monetdb/jdbc/MonetDatabaseMetaData.java @ 302:1b6c514106ce
Added table aliases and use them in all meta data SQL queries to reduce query size.
Also use JOIN syntax in FROM clause instead of old way of joining in WHERE clause. This further reduces size.
In getIndexInfo() no longer issue a SELECT COUNT(*) query when the schema or table name contains wildcard: %.
In getIndexInfo() added missing join condition
AND i.\"table_id\" = k.\"table_id\"
to make sure the index and the key constraint both reference the same table
and extended the output to also lists info for primary keys (which also use an internal hash index).
