Hi guys,
I came looking for some guidance on creating a simple query parser that will support ors.. and ands..
The idea would be something like this.
I specify the query like this
Column1 Cat / Column2 Dog & Column 3 Rabbit --------- Where (/ is or) and (& is and)
Anyone know if there is something like that already implemented somewhere, so that I can put it as a wrapper on a bigger program.
Any help on this greatly appreciated,
Ed.
Wow. Ugg.
No advice, other than to not reinvent the wheel. There are lot's of free relational databases out there that support a level of SQL that you would be hard pressed to match without months of an investment in time.
And, just think - you could spend more time on your bigger program and not this grunt work.
Yes, you can use SQL and connect it with C++ code. Like http://www.alhem.net/sql_cpp_tutorial/tut_1.html.
So you can use MySQL for example, build a database and do whatever query you want with it with C++. Dunno and specific wrappers to recommend.
Take it as this.. I already have the database which is an implemented algorithm.. I need a parser to pass the queries to this database.. I'm not using MySQL.. or an DBMS.. I just need to make my own parsing query language.Quote:
