[naviserver-devel] dbi_dml

[Gustaf N. <ne...@wu...>]

Hi Stephen,

in contrary to the documentation, dbi_dml does not return the number
of rows affected by the query. Typically the dbi_* tcl commands
are implemented via Exec() followed by a retrieving cmd, like in

dbi_1row does an Exec() + NextRow()
dbi_rows does an Exec() + many NextRow(),
etc.

but dbi_dml does the Exec() and nothing after that to
retrieve the result (which is in pg: PQcmdTuples(res)).

What is your suggestion to fix this?
- extend the record of Dbi_DriverProc? (new function)
- mangle NextRow() to return the result in the dml case
- extend the Dbi_Handle structure such that Exec()
   can return this value directly?
others?
