Hello,
I am currently developing an iOS app with Xcode 7.2, Swift 2.0, and iOS 9.2. I have implemented iAds, and it works perfectly. However in my region the fill rate is not high, and I would like to use Google's AdMob to advertise on my app, as a backup. I would like for the AdMob banner ad to show up when iAd does not receive an ad. Note that I am new to Swift, and have no knowledge of Objective-C. Thanks.

Answer: 
Your connection string looks like it's not in line with what's specified in the [documentation](https://msdn.microsoft.com/en-us/library/ms378428(v=sql.110).aspx).

Try changing your connection string from:

```
"jdbc:sqlserver://localhost:1433;sa;VMADMIN#123;" 

```

To:

```
"jdbc:sqlserver://localhost:1433;user=sa;password={VMADMIN#123};"

```
try this it will definitely work

```
Connection con = DriverManager
                    .getConnection("jdbc:sqlserver://localhost:1433;databaseName=<name of your database>;user=sa;password=VMADMIN#123");  

```
