DB2将DETACH下来的临时表ATTACH到分区表报错SQL20307N SQLSTATE=428GE

1.报错信息

DB21034E The command was processedd as an SQL statement because it was not a valid Command Line Processor command.

During SQL processing it returned:

SQL20307N   Table "TEST.TABLE_PART20200313" cannot be attached to table "TEST.TABLE_H".

Reason code = "1".  SQLSTATE=428GE.

2.错误分析

报SQL20307N错误是因为目标表与临时表的特征不完全匹配。

根据Reason Code = "1" 可判断出错误原因为临时表与目标表列数不一致。(通过db2  ?  SQL20307N查阅)

3.解决方法

比对临时表和目标表的表结构，将两者调整成一致的结构，然后再执行ATTACH命令。
