Hello,

In a old program of mine, there is a index on
numeric Customer-Numbers ( CDX ).

The index is => Index on STR(number)
index on LTRIM(STR(number)) doesn't work.

When you do a seek on this field ( N 5 0 )
as a sample you seek < 5 > you have to do - - - - 5
4 blanks + "5"

Must i write a function for this ?

Regards

Uwe

Index on numeric work fine

index on number to ....

and then seek 5 or whatever else

no problem with it, i have many numeric indexs in my app

Uwe,

index on LTRIM(STR(number)) doesn't work.

this is normal because all index keys need to be of constant same length.

Moreover it's a bad design to use numeric fields for indexing.
They are better used for numeric operation / calculation.

If you can't avoid it i'd take 'strzero( nVal, nLen, nDec )' for indexing and searching.

Detlef Thank you,

Yes it is a very old application and
to much work to change it.

I will try Strzero
