Re: SQL Deletes

IMHO, you're not going to get much of a performance boost by using SQL over
a CHAIN in this situation.  Sounds like it would be simplier to code a
CHAIN operation for what you're doing.

Subject:    SQL Deletes


Good morning from a slightly damp Midwest!

I have a question regarding multiple deletes in a RPG
/Free program I am writing. I have a status field
that, at anytime during the parsing of an XML "sheet",
can be set to 'F' to fail a document (through errors
like letters where there are supposed to be numbers or
blanks for required information).

The program ultimately updates/writes to 7 different
db files, BUT it writes as it goes (I chose to reuse
certain fields rather than trying to guess how many
unique fields I would need since using arrays was
poo-pooed by the team leads). So if file 4 fails, then
there are fragments in 1,2 and 3 that I need to get
rid of. I think an SQL delete would be faster to write
than a set of repeated CHAIN deletes.

How would I pass in the parameters of document number,
date and year? I honestly havent messed much with SQL
since school (and that was only on a faked up Oracle
db for Oracle class).

Thanks for any advice in advance!
