Hi,
From the DBI::DBD docs in "The dbd_db_login6 method" I read:
=====
Here’s how you fetch them; as an example we use hostname attribute,
which can be up to 12 characters long excluding null terminator:
SV** svp;
STRLEN len;
char* hostname;
if ( (svp = DBD_ATTRIB_GET_SVP(attr, "drv_hostname", 12)) && SvTRUE(*svp)) {
hostname = SvPV(*svp, len);
DBD__ATTRIB_DELETE(attr, "drv_hostname", 12); /* avoid later STORE */
} else {
hostname = "localhost";
}
=====
My question concerns the comment saying "avoid later STORE". If I have a
DBD::ODBC specific attribute which a) may be specified on the connect
call and b) is copied to any statement handles when they are created and
c) may also be on a statement handle, should I be calling
DBD__ATTRIB_DELETE? and what does that "avoid later STORE" really mean?
