Indeces .ntx, multi tag

[Luigi Ferraris]

Hi folks,
about ntx file

1) Q. about ORDCONDSET function, property <lAdditive>: it's only affects while ORDCREATE execution?

2) Q. I need to recreate all orders (multi tags) in an order bag.

If there was a tag, now unused, I need to manually remove it or is there a way to remove all tags before using ORDCREATE? e.g. ORDBAGCLEAR()

Many thanks in advance.

Hi to everyone,

I found that using next code (as example), the index file (physical file) is automatically removed.

I don't know this behaviour.

   ic := 1
   WHILE( ! EMPTY( (warea)->(ordName( ic )) ) )
      (warea)->(ordDestroy((warea)->(ordName( ic ))))
   ENDDO

Best regards.

Normal INDEX ON ...  close all current used index files (BAG) , create new and use only this new file index. ADDITIVE no close used indexes

Sample.

INDEX ON keyA TO indA        //opened indexes:  indA

INDEX ON keyB TO indB        //opened indexes:  indB  

INDEX ON keyC TO indC  ADDITIVE      //opened indexes:  indB , indC

for mulit tag:

INDEX ON keyA TAG aa TO indA        //opened indexes:  indA->aa

INDEX ON keyB TAG bb TO indA        //opened indexes:  indA->aa,bb

INDEX ON keyC TAG cc TO indB        //opened indexes:  indB->cc

INDEX ON keyD TAG dd TO indA  ADDITIVE    //open indexes:  indB->cc , indA->aa,bb,dd

If You use to recrate:  INDEX ON ... TAG .. TO indFile         simply delete file "indFile.ntx"

if REINDEX     use before command:  DELETE TAG <(tag1)> [IN <(bag1)>] [, <(tagN)> [IN <(bagN)>]]  for unused tags
