Re: Re writing CL in RPG

Thanks to all who responded. My main goal is to make the program to run faster.
I tested with the code below and RPG and CL as well. RPG seems to be taking less time , quite nt sure why.
I am under impression that CPYF and SQL do some blocking by default and they dont use maximum block size, is it true?
The number of records that is getting written(/copied) are nearly 100,000 and file contains more than a million.

Thanks,

Donna.

You could also try using SQLRPGLE:

// copy data from ABBC.FILE to XYZ.MONY
// Note: This only copy F records or ID/name/acct records
// that exist in GEUKACT into XYZ.Mony
exec sql
insert into "XYZ.MONY" a
(select * from "ABBC.FILE" b
where
b.ID = 'F' or
exists
(select 1 from GEUKACT c
b.ID=c.ID and b.name=c.name and
b.acct=c.acct
)
);

// copy data from AFILE to XYZPOSREC
// Note: This only copy F records or ID/name/acct records
// that exist in GEUKACT into XYZPOSREC
exec sql
insert into "XYZPOSREC" a
(select * from "AFILE" b
where
b.ID = 'F' or
exists
(select 1 from GEUKACT c
b.ID=c.ID and b.name=c.name and
b.acct=c.acct
)
);


Note: I've not tested or run thru SQL syntax check.

Hi
Below is my code. I am trying to replace copy commands

program by
writing RPGLE.

Is this a good design , will this run faster? I would

like to know
your opinions and suggestions.

Thank you for your time. The number of records in

AFILE usually more
than a million.

LOOP: RCVF

MONMSG MSGID(CPF0864) EXEC(GOTO

CMDLBL(END))

CPYF FROMFILE(*LIBL/ABC.FILE) +

TOFILE(*LIBL/XYZ.MONY)

MBROPT(*ADD) +

INCREL((*IF MID *EQ &YID)

(*AND +

MNAME *EQ &YNAME) (*AND

MACCT *EQ &YACCT))

CPYF FROMFILE(*LIBL/AFILE) +

TOFILE(*LIBL/BFILE)

MBROPT(*ADD) +

INCREL((*IF PID *EQ &YID)

(*AND +

PNAME *EQ &YNAME) (*AND

PACCT *EQ &YACCT))

GOTO CMDLBL(LOOP)

END: CPYF FROMFILE(*LIBL/ABC.FILE) +

TOFILE(*LIBL/XYZ.MONY)

MBROPT(*ADD) +

INCREL((*IF MID *EQ F))

TOFILE(*LIBL/XYZ.MONY)

MBROPT(*ADD) +

INCREL((*IF MID *EQ F))

CPYF FROMFILE(*LIBL/AFILE) +

TOFILE(*LIBL/BFILE)

MBROPT(*ADD) +

INCREL((*IF PID *EQ F))
