             Project: logback-classic
          Issue Type: Sub-task
          Components: appender
    Affects Versions: 0.9.18

To comply with local project rules, it can be helpful if the table and column names used by DBAppender could be overridden. The easiest way to solve this problem is for  DBAppender  to delegate the resolution of table names and columns to a different class, say DBNameResolver. Here is a possible interface:

interface DBNameResolver {
  String getTableName(String standardTableName);
  String getColumnName(String standardColumnName);
}

The default implementation of DBNameResolver could be:

class DefaulDBNameResolver implements DBNameResolver {

  public String getTableName(String standardTableName) {
    if("logging_event".equals(standardTableName) {
      return standardTableName;
    }
    if("logging_event_property".equals(standardTableName) {
      return standardTableName;
    }
    if("logging_event_exception".equals(standardTableName) {
      return standardTableName;
    }
    throw new IllegalArgumentException(standardTableName + " is an unknown table name");
  }

  String getColumnName(String standardColumnName) {
     ...
  }
}

If a user wanted to use different names she would simply implement DBNameResolver according to her requirements.

Any volunteers to implement this?
