Depopulate but keep Customs, Places, Sources #database #places #placedetails #sourcetemplates #sources #facttypes #custom #media #roles

This script deprecated in favour of Database - Copy Master Lists to Shell (2014-10-13).

Makes an empty Master from current database, preserving custom fact types and source templates, Places, Master Sources and associated Repositories and Addresses, and Place/Source Media. Written for RM4 with instructions to edit for RM5.
CustomDatabaseShell.sql
There are two ways to do this:
  1. Use SQLite Developer with a fake RMNOCASE collation and execute the query directly on a .rmgc database. This should pose no risk as it adds nothing to the database. Moreover, RM5 is especially assured because it has the REINDEX Database Tool which will rebuild the indexes against the internal collation.
  2. Use other SQLite managers with the queries on Convert Database to NOCASE to create a NOCASE clone of the database. Then run CustomDatabaseShell query to depopulate the database. This NOCASE clone is usable in RM and probably will not throw up any sorting or indexing issue with the English alphabet, any more so than would the original; however, other language alphabets may be problematic. It would be advisable to add a dummy person, assign every fact, source and place to him, and drag and drop to a new database to restore the structure to RMNOCASE.
