I am using Virtuoso
engine(http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/).
For entering a query into Virtuoso engine, the following needs to be
done:
The virtuoso engine starts and gives the command prompt:
[myMachine]$ ./isql 1111
Connected to OpenLink Virtuoso
Driver: 07.20.3213 OpenLink Virtuoso ODBC Driver
OpenLink Interactive SQL (Virtuoso), version 0.9849b.
Type HELP; for help and EXIT; to exit.
SQL>
The query `"sparql select ?a?b?c where{graph ?g{?a ?b ?c} };"` is
entered by the user as following:
[myMachine]$ ./isql 1111
Connected to OpenLink Virtuoso
Driver: 07.20.3213 OpenLink Virtuoso ODBC Driver
OpenLink Interactive SQL (Virtuoso), version 0.9849b.
Type HELP; for help and EXIT; to exit.
SQL> sparql select ?a?b?c where{graph ?g{?a ?b ?c} };
Now in order to automate the process of inserting queries into
Virtuoso I wrote the user entered value:`"sparql select ?a?b?c
where{graph ?g{?a ?b ?c} };"` into a text file (mytext.txt) and used
the following command:
[myMachine]$ ./isql 1111 < mytext.txt
However still the Virtuoso prompt appears as the following -- asking
me to enter the query string:
[myMachine]$ ./isql 1111 < mytext.txt
Connected to OpenLink Virtuoso
Driver: 07.20.3213 OpenLink Virtuoso ODBC Driver
OpenLink Interactive SQL (Virtuoso), version 0.9849b.
Type HELP; for help and EXIT; to exit.
SQL>
Is there some way in linux or c++: by which using shell script (for
linux) or system calls for c++ I can enter my query string into
Virtuoso. I need to run 10,000 queries therefore manually entering
10,000 queries in Virtuoso is a pain.

With Warm Regards,
