Stop function on MySQL connection error

How can I stop the function if MySQL could'nt connect to database?

Code:

_mySqlConnection = _mySql.OpenDb("ip", 3306, "etc", "etc", "ip", this);
// Lets say mysql host is down, how can I stop the function from going to code?//CODE

 

have you tried, try/catch?

Code:

try {
     _mySqlConnection = _mySql.OpenDb("ip", 3306, "etc", "etc", "ip", this);
}
catch (Exception e)
{
     Puts(e);
}

This could allow you to keep trying to connect on failure as well

 

The MySQL extension catches exceptions currently.
_mySqlConnection might be null as a result of that, and in either case, once you run a query against the DB, the result set will be null as well if it can't query the DB.
Otherwise, @Calytic might be able to provide more insight
