Hi,
I don't know the best way ;-)
Here is what I do (this is the `clumsy way'):
Dump the query output as a dumpfile delimited by tabs.
Reformat the output for pgsql...
NOTES: FoxPro DOS gave me an EOF (^Z) that had to be stripped.
As DOS does a ^J^M dance (CRLF) these embedded chars must also be
stripped. The / / bit in the script below was to rm any bad date
values - making them proper NULLs. The empty date placeholders must
be nulled BEFORE you strip away the double quotes otherwise char strs
end up with embedded nulls. ;-)
Next the double quote FoxPro nulls ( "" ) are converted to proper
NULLs. Lastly, the surviving quotes are stripped.
IMPORTANT: the ^Z and ^M are _literals_. I edit them into the script
with i, ^V, ^M (in vi...)
#!/bin/sh
tput clear
echo -n "Enter file to be converted: "
read file
sed -e '/^Z/d' $file > $file.step0
sed -e 's/^M//g' $file.step0 > $file.step1
sed -e 's/ /\\N/g' $file.step1 > $file.step2
sed -e 's/""/\\N/g' $file.step2 > $file.step3
sed -e 's/"//g' $file.step3 > $file.pg
rm $file.step0
rm $file.step1
rm $file.step2
rm $file.step3
After this, add
COPY table_name FROM stdin;
to the top of your dumpfile.
And
\.
to the end.
Then run:
psql -e db_name < dumpfile_name
BTW, if you have questions, fire away. All of us FoxPro victims must
stick together! (I recommend a pint of bitter be kept handy during the
process of hacking the foxpro psuedo-sql into postgres ;-)
Cheers,
Tom
