How can I allow users to submit q queries and interpret them as a string?

Question

I want to allow users to write real q queries like

select from table where date=.z.d

Is it possible to use something like

E)select from table where date=.z.d

and then use the input to that E) to parse the query and do stuff with it?

Answer 1

If you create a function called .E.e, anything you pass to it will be interpreted as a string, so you can do something like this to start parsing your input:

q).E.e: {" " vs x}
q)E)select from table where date = .z.d
"select"
"from"
"table"
"where"
"date"
,"="
".z.d"
