How to print SQL statement in codeigniter model

Question

I have a sql statement in my model,

I then say

$query = $this->db->query($sql, array(fields, fields1);

if ($query) {
    return true:
} else {         


        

Answer 1

You can simply use this at the end..

echo $this->db->last_query();

Answer 2

I'm using xdebug for watch this values in VSCode with the respective extension and CI v2.x. I add the expresion $this->db->last_query() in the watch section, and I add xdebugSettings node like these lines for get non truncate value in the launch.json.

{
  "name": "Launch currently open script",
  "type": "php",
  "request": "launch",
  "program": "${file}",
  "cwd": "${fileDirname}",
  "port": 9000,
  "xdebugSettings": {
    "max_data": -1,
    "max_children": -1
  }
},

And run my debuger with the breakpoint and finally just select my expresion and do click right > copy value.
