Set the order a database’s tables — what the user sees as tabs — appear in, left to right. Records, columns and names are untouched. Use it when the user asks to move a tab, put tables in a particular order, or when tables you created should read in a sensible sequence (e.g. “Projects” before “Tasks”). Pass every table id of the database exactly once, in the new order; call DescribeDatabase first for the current ids, since a list that misses or adds a table is refused. Requires edit access to the database. The response is the schema after the change. If database is null, the reorder still succeeded; call DescribeDatabase using databaseId before continuing.
