the following code:

#select * from pagosprueb

+numfields      is the number of fields u spect,

</package>
aders: 0GetColumnHeaders: 0GetColumnHeaders:
0GetColumnHeaders: 0GetColumnHeaders:
0GetColumnHeaders: 0GetColumnHeaders:

lots of getcollumnheaders:0 also omited

im working on a win2000 sp 4 1.7ghz with ODBC 3.0 Tcl
Extension and tcl 8.4.11.0 from activestate

this:

GetColumnHeaders: 0

is printed every time i fetch a new row, since the
output of my program is then fed to another program (an
xml parser)
then the output warning generated by the extension is
unacceptable, it should set errno, or whatever it uses
for error handling instead of tossing output into my
xml file, right?

im shure there is a smiple fix for this....

btw: command line is:

tclsh dumpdb.tcl "select * from pagosprueb" 11 >report.xml
