public String getTableNameFromQualifiedTableName(String tableName) {
        return tableName.substring(tableName.lastIndexOf(".") + 1);
    }
When using a table name in a generated SQL query, how (if at all)
should we escape that column name? e.g., a table named "table"
may need to be quoted with backtiks: "`table`".

@param tableName the table name as provided by the user, etc.
@return how the table name should be rendered in the sql text.
