/**
* This code is a bit tricky. We have to execute this right at the beginning before actually iterating over all the
* tables and generating the join string as we may have to delete a table from the tables. If we did not delete
* this table upfront, we would have maybe already added a joinString for that table, even though it will be later
* removed by another table. This means if we wouldn't delete/unset that table upfront, we would need to alter
* an already generated join string which would not be really nice code as well.
*
* Next problem is, because we are deleting a table, we have to remember the "joinOn" string for that table in a
* property "nonVisitJoins". Otherwise we would not be able to generate the correct "joinOn" string when actually
* iterating over all the tables to generate that string.
*
* @param $tableName
* @param $tableNameToJoin
