You must use parameter substitution and sprintf() as shown in the example code. In this case, replace the pinID with an actual value.


const char UPDATE_DATA[] = "UPDATE db1.tbl1 SET temp = %s";


char query[64];
char temperature[10];
dtostrf(value_read, 1, 1, temperature);
sprintf(query, UPDATE_DATA, temperature);
