Hi,
=20
I'm having difficulty writing to an ASCII file with a serialRecord.
=20
I've read in the reference guide that the specified file name is a =
logical
name and that it is binded at run or build time to a physical name. =
(Which
could be platform specific). Howerver in the guide is only described how =
it
is done logically, but not where or how exactly. Can somebody please =
help me
with this....
=20
Also if there are more books available besides the 980 pages large
referenece guide (with a lot of theory but not a lot of complete =
examples) I
would appreciate it to know.
=20
I have the following code (snippets):
=20
DataDef:
=20
package data;
=20
Record Egltest type SQLRecord { tableNames =3D ("ROB.EGLTEST"), =
keyitems =3D
("cust_no") }
cust_no CUST_NO {column =3D "CUST_NO"};
cust_name CUST_NAME {column =3D "CUST_NAME", isNullable =3D yes};
end
=20
// define the data to store in the session for a detail of Egltest
Record EgltestKeys type BasicRecord
cust_no CUST_NO;
end
=20
// define the data to store in the session for a list of Egltest
Record EgltestSessionListData type BasicRecord
// index of the first item of the current page
_pageIndex int;
end
=20
Record eglfile type serialRecord { filename =3D "myfile" }
10 cust_no int;
10 cust_name char(30);
end
=20
main package:
=20
package testpkg;
=20
import data.*;
=20
Program testprg
=20
function main()
rec1 egltest;
rec2 eglfile;
=20
rec2.resourceAssociation =3D "c:\\test.txt";
=20
open selectRec with #sql{
select cust_no, cust_name
from rob.egltest
}
into rec1.cust_no, rec2.cust_name;
=20
forEach (from selectRec)
move rec1 to rec2 byname;
add rec2;
syslib.wait(1);
end =20
sysLib.wait(5);
end
=20
end
=20
