Re: Use of regular expression

Aaron,

One small tweak to your SQL

SELECT * FROM MYTABLE WHERE UCASE(MYFLD) LIKE '%RICK%'

I normally like to do it that way so I don't have to worry about the case,
but I don't know what it would do to the amount of time it may or may not
add to the search.

I agree with Alan, try using SQL. Try this:

SELECT * FROM MYTABLE WHERE MYFLD LIKE '%rick%'

What about using SQL?

I'm wondering if using regular expressions is a good way to handle a

word

search. What I need is an exact match of a series of characters, say
'rick', in a character field. I have only used regular expressions a

couple

of times and the syntax still gets me confused. I think I see a way to

do

this with with something like r{1}i{1}c{1}k{1}.

I know I can do this with the %SCAN op code. The reason I'm thinking

about

using regular expressions is the search will be over a table of close

to

1

billion records and I'm looking for efficiencies any place I can find

them.

If an expression can be created I want to do some comparisons between

using

a regular expression and %SCAN to see which is really the best

performer.

Any thought would be appreciated.
