版本：TiDB V6.2
问题：
基于SparkSQL执行insert into…select… 报错，无论什么表都只提示源表只有3个列，错误信息如下：
Cannot write to ‘us_stock_ads.ca-suspension’, not enough data columns:
Table columns: ‘symbol’, ‘startdate’, ‘enddate’, ‘reason’, ‘duration’
Data columns: ‘symbol’, ‘reason’, ‘duration’ 。
执行SQL：
insert into us_stock_ads.ca-suspension
(symbol,
startDate,
endDate,
reason,
duration)
SELECT replace(replace(replace(replace(STOCKCODE,’.F’,’.US’),’.A’,’.US’),’.O’,’.US’),’.N’,’.US’) as symbol,
SuspensionStartDate as startDate,
SuspensionEndDate as endDate,
ResumptionReason as reason,
SuspensionDuration as duration
FROM us_stock.ccs_SuspensionResumption
