Question

What is a good method for parsing an sql string into it separate components. I’v tried with a regex, however I can’t get it to work just right.

Say for instance:

'SELECT * FROM tbl WHERE user_id > 50' 

Would create an array with all the components

$arr[0] = 'SELECT'; $arr[1] = '*'; $arr[2] = 'FROM'; 

ect…

Thank you

I’d go for a sql parser that could be integrated to your language: don’t reinvent the wheel.

I haven’t used one in particular to recommend, but I’m sure that you can find one that do what you need.
