Question: I used to work with Cesium ion and their map engine in my project.
I want to know if there are any better or equal map engines out there.
found some options and am not sure about them.

1. MapTiler
2. Carmenta
3. ArcGis (Although I'm not sure about this one)

Thanks in advance

Answer: 
There are 3 different JDBC execute functions:

* `PreparedStatement.execute` is for executing any statement; including DDL statements such as `CREATE TABLE`, etc.
* `PreparedStatement.executeQuery` is for executing `SELECT` statements.
* `PreparedStatement.executeUpdate` is for executing DML statements such as `INSERT`, `UPDATE`, `DELETE` or `MERGE`.

You want `PreparedStatement.executeUpdate` and not `PreparedStatement.executeQuery`.

You also need to check that your statement/transaction is committing the data; if it is not then you need to explicitly `COMMIT` the data.
For inserts and deletion, it should be executeUpdate().
