newbie tcl & sql question
My guess would be the select did not return any rows, therefore category was
never created.
I'd like to see the results of:
#!/bin/sh
# the next line restarts using tclsh \
load fbsql.dll
sql connect localhost root "test"
sql selectdb test
array set category {}
sql startquery "select * from mt_category" -array category
puts {category:}
parray category
puts {-------}
sql endquery
sql disconnect
