Select operation with esp8266

I used the provided demo and just few alteration and run. below are my code

#include <Arduino.h>

#include <ESP8266WiFi.h>                        // Use this for WiFi instead of Ethernet.h
#include <MySQL_Connection.h>
#include <MySQL_Cursor.h>

IPAddress server_addr(192,168,68,104);        // IP of the MySQL *server* here, local server
char user[] = "admin";                        // MySQL user login username
char password[] = "admin";                    // MySQL user login password

char query[] = "SELECT message FROM arduino.arduino WHERE counter < 10";

// WiFi card example
char ssid[] = "amigos";                         // your SSID
char pass[] = "c3l3br1t7";                      // your SSID Password

WiFiClient client;                              // Use this for WiFi instead of EthernetClient
MySQL_Connection conn(&client);
MySQL_Cursor* cursor;

void setup()
{
  Serial.begin(9600);
  while (!Serial);                              // wait for serial port to connect. Needed for Leonardo only

                                                // Begin WiFi section
  Serial.printf("\nConnecting to %s", ssid);
  WiFi.begin(ssid, pass);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
                                                // print out info about the connection:
  Serial.println("\nConnected to network");
  Serial.print("My IP address is: ");
  Serial.println(WiFi.localIP());

  Serial.print("Connecting to SQL...  ");
  if (conn.connect(server_addr, 3306, user, password)) {
    Serial.println("OK.");
    cursor = new MySQL_Cursor(&conn);
    cursor->execute(query);
    Serial.println("Connected to dbs");
  }
  else
    Serial.println("FAILED.");
}

void loop() {
  delay(2000);

  Serial.println("\nRunning SELECT and printing results\n");
  MySQL_Cursor *cur_mem = new MySQL_Cursor(&conn);                          // Initiate the query class instance
  cur_mem->execute(query, false);                                            // Execute the query with the PROGMEM option = true
  delay(500);
  cur_mem->show_results();                                                  // Show the results
  delay(500);
  delete cur_mem;                                                           // Deleting the cursor also frees up memory used
}

and here the output in my serial monitor

Error: 1 = .

Its printing the correct output but why the error are keep on coming.

Also if using PROGMEM with changes below

char PROGMEM query[] = "SELECT message FROM arduino.arduino WHERE counter < 10"; cur_mem->execute(query, true);
