sql存在多数据库时，报【错误日志:Table 'db1.tableA' doesn't exist】错误

[weeway]

sql

SELECT * FROM `db2`.`tableA` AS a 
LEFT JOIN `db1`.`tableB` AS b ON a.company_code = b.CompanyCode 
WHERE a.company_code = 'xxx' AND a.company_type = '1'

2022-09-29 17:20:47 24980 [Note] 第1步: 对SQL解析优化之后得到的SQL:select `*` AS `*` 
from (`db2`.`tableA` `a` left join `db1`.`tableB` `b` on((`a`.`company_code` = `b`.`CompanyCode`))) 
where ((`a`.`company_code` = 'xxx') and (`a`.`company_type` = '1'))

2022-09-29 17:20:47 24980 [Note] 第2步：开始解析where中的条件:(`a`.`company_code` = 'xxx')

2022-09-29 17:20:47 24980 [Note] show index from tableA

2022-09-29 17:20:47 24980 [Note] show table status like 'table'

2022-09-29 17:20:47 24980 [Note] select count(*) from ( select `company_code` from `tableA` FORCE INDEX( PRIMARY ) order by company_id DESC limit 1234) `a` where (`a`.`company_code` = 'xxx')

2022-09-29 17:20:47 24980 [Note] 第3步：表tableA的行数:1234,limit行数:1234,得到where条件中(`a`.`company_code` = 'xxx')的选择度:1234

2022-09-29 17:20:47 24980 [Note] 第4步：开始解析where中的条件:(`a`.`company_type` = '1')

2022-09-29 17:20:47 24980 [Note] show index from tableA

2022-09-29 17:20:47 24980 [Note] show table status like 'tableA'

2022-09-29 17:20:47 24980 [Note] select count(*) from ( select `company_type` from `tableA` FORCE INDEX( PRIMARY ) order by company_id DESC limit 1234) `a` where (`a`.`company_type` = '1')

2022-09-29 17:20:47 24980 [Note] 第5步：表tableA的行数:1234,limit行数:1234,得到where条件中(`a`.`company_type` = '1')的选择度:1

2022-09-29 17:20:47 24980 [Note] 第6步：开始解析join on条件:a.company_code=b.CompanyCode

2022-09-29 17:20:47 24980 [Note] 第7步：开始选择驱动表,一共有1个候选驱动表

2022-09-29 17:20:47 24980 [Note] explain select * from tableA as a where (`a`.`company_code` = 'xxx')

2022-09-29 17:20:47 24980 [Note] 第8步：SQLAdvisor结束！错误日志:Table 'db1.tableA' doesn't exist
