我正在运行Tableau,并连接到MySQL数据源。当我选择"转换为自定义SQL"选项,我收到一个错误。错误如下:
[MySQL][ODBC 5.3(w) Driver]Unknown column 'Name' in 'field list'
以下是查询:
SELECT `TableauSQL`.`Name` AS `Name`
FROM (
SELECT `projectData`.`_id` AS `_id`,
`projectData`.`approvalfy` AS `approvalfy`,
... many columns, none of which are 'name' ...
`projectData`.`url` AS `url`
FROM `projectData`
) `TableauSQL`
LIMIT 10000
那么为什么Tableau会生成一个查询,其中选择了不存在的列?
