[Letodb-developers] INDEX ON bug

[Nenad B. <nba...@wi...>]

Hello! 

 

INDEX command have a bug: 

 

USE Table NEW

INDEX ON Upper(t_name) TO (cIndex) TAG Test

 

This commands open table _without_ index, and then creates new index file. But, if exist old index file, LetoDB for some reason open this old file before creates new. For example, if old file contains bad function - "Wrong(t_name)", Leto reports error "Undefined function". I use NTX index files. 

 

Best regards, 

 

NB

   It is Harbour's DBFNTX opens that existing index file before to 
create it because the tag name is set. Harbour supports multitag ntx 
indexes, so it tries to add new tag in existing index file.
   Simply delete indexes with wrong index expressions.
