如何解决UNION在Spring数据JPA原生查询两张表

例如：txrh_bcaterms UNION txrm_bcaterms
I have a requirement where i need to fetch number of record both the table using JPA native UNION query for Pagination
table 1=>txrh_bcaterms
table 2=> txrm_bcaterms
注意：实际上stepid是txrh_bcaterms表的主键，txrm_bcaterms表中没有stepid
错误 ------- 在 ui 中我通过了机构 =BC/AC/EC 然后 UNION 查询能够执行和获取数据 但如果我通过了 SC，则低于异常
@Query(nativeQuery = true,value= "SELECT "
+ " customerid,"
+ "finance_type,"
----------
-------etc----
+ "institution,"
+ "limit_groupid,"
+ "tx_booking_location,"
+ "finance_tenor_days,"
+ "margin_type,"
+ "additional_margin_percentage,"
+ "margin_percentage,"
+ "stale_document_condition_proforma_fin,"
+ "customer_name "
+ "from "
+ "txrh_bcaterms "
+ "where "
+ " institution=:institution "
+ "AND tx_booking_location=:txBookingLocation "
+ "OR finance_type=:financeType "
+ "OR customerid=:customerID "
+ "OR limit_groupid=:limitGroupID "
+ "UNION "
+ "SELECT "
+ "customerid,"
----------
-------etc----
+ "institution,"
+" finance_tenor_days,"
+ "stale_document_condition_proforma_fin,"
+ "customer_name "
+ "from txrm_bcaterms "
"
+ " institution=:institution "
+ "AND tx_booking_location=:txBookingLocation "
+ "OR finance_type=:financeType "
+ "OR customerid=:customerID "
+ "OR limit_groupid=:limitGroupID "
)
Page<Map<String,Object>> historyAndMaster(@Param("institution") String institution,@Param("txBookingLocation") String txBookingLocation,@Param("financeType") String financeType,@Param("customerID") String customerID,@Param("limitGroupID") String limitGroupID,Pageable page);
=>如果列数不同，那么它是如何工作的 BC/AC/EC
Caused by ERROR: each UNION query must have the same number of columns
