报错:
SQL: select h.* , l.listPrice from hospital h,list l,hospital_list hl where h.hhospitalId = hl.hlhospitalId and l.llistId = hl.hllistId and l.listName = ?

Cause: java.sql.SQLSyntaxErrorException: Unknown column 'h.hhospitalId' in 'where clause'

; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Unknown column 'h.hhospitalId' in 'where clause'

列名 没写错嘛 ?hhospitalId 这个字段有没有?

h.hhospitalId = hl.hlhospitalId
