This Technical Note explores the issue of upgrading databases that contain subtables to 4D v11 SQL.
Subtables no longer exist in 4D v11 SQL. A conversion path is available for single-level subtables, which allows subtable code to continue working. Multi-level subtables are not supported at all, so steps must be taken to insure that data is not lost from these subtables before converting to 4D v11 SQL.
This Technical Note addresses both single-level and multi-level subtable scenarios.
