Very minor security fix: schemaName and tableName wasn't escaped. If any of the two contained a string with a double quote in it, then that would enable an SQL injection. This was previously a feature of tableName, before the introduction of a separate schemaName, as that allowed a schema to be defined as part of tableName. Defining schema name through tableName is still supported after this fix, but is now deprecated.
Fix: Errors wasn't propagated properly. Fixed in #150. Thanks @bobnil!
