Question on accessing table passed as parameter via C API

["Henderson, Michael D" <michael.d.henderson@...>]

I’m trying to dynamically bind parameters based on a table being passed to my C function.

 

The Lua side looks like

 

query = “select * from foo where key = :key and foo between :lbound and :ubound”

parms = { key = ‘JAN03’, lbound = 0, ubound = 30}

 

exec(query, parms);

 

And the library function looks something like

 

// C library

nParms = lua_istable(L,2) ? lua_objlen(L,2) : 0;

 

for (idx = 1; idx <= nParms; ++idx) {

  int type = // how do I get the type of the parameter?

 

  switch (type) {

  case LUA_TNUMBER:

     bindNumber(nameOfParameter, valueOfParameter);

       // how do I get the name of the parameter?

       // how do I get the value of the parameter?

 

I’ve been going through the PIL and looking at the source of luasql and luasqlite, but I don’t see anything like what I’m trying to. I’d appreciate being pointed in the right direction.

 

Thanks,

Mike
