Question

我在sql server中有2个表。我的目标是将第一个表列（TCODES）与第二个表列名称（ST_Description）进行比较。如果匹配，则在第二个表中选择所有列数据。我可以在控制台中获取所有数据。但是我是无法继续。你最早的回复会帮助我。

DB中的第一个表数据：

#TCODES(column name)#
  [SAT,
 ZN4963_PROM_01,
 /LCLCDP/BVOUTPUT,
 /LCLCDP/CSV_IDOC_CRE,
 /lclcdp/export_settl,
 /lclcdp/itemization,
 /lclcdp/TUD,
 /LCLCDP/UPLOAD_CSV,
 /N/LCLCDP/CSV_IDOC_CRE,
 /n/posdw/mon0 ,
 /posdw/mon0,
 AL11,
 ARCU_COIT1,
 AS01,
 AS02,

DB中的第二个表数据：列名称是版本名称

#Release_Name#      ##Cycle_Name##                 ###ST_DESCRIPTION ###
-------------------------------------------------------------------------------

Answer 1

通过公共唯一列首先join两个表，然后使用WHERE子句来映射您的条件。

SELECT * FROM TABLE2 
JOIN ON TABEL1.ID = TABLE2.ID
WHERE TABLE1.TCODES = TABLE2.ST_DESCRIPTION

比较2个表数据并使用java打印第二个表数据的所有列
