When I try to insert data into TABLE, this error occurs.
The reasons caused the error can be concluded as below
1. Duplicate records.
ID | TYPE | SCHOOL | |
1 | 1 | C | HKUST |
2 | 1 | C | HKUST |
2. Duplicate records with the key.
For example, TABLE A use field ID and TYPE as key.
Data of key fields are same.
ID | TYPE | SCHOOL | |
1 | 1 | C | HKUST |
2 | 1 | C | CITYU |
To avoid the case, please make sure the uniqueness of data.
确保事务的ACID.
A Atomic 原子性
C Consistency 一致性
I Isolation 隔离性
Durability 持久性
If in PeopleSoft, remember to truncate table " %TruncateTable(%Table(temporary table))" before "insert into temporary table".
