There could be several reasons for the invalidity of selectKey in MyBatis.<\/p>\n

    \n
  1. Some databases do not support selectKey, which means that tools like MySQL’s LAST_INSERT_ID() or Oracle’s sequence may not work properly for automatically retrieving primary keys.<\/li>\n
  2. There is an error in the selectKey configuration: make sure that the correct properties like keyProperty and order are set when configuring selectKey, otherwise the generated primary key value cannot be obtained correctly.<\/li>\n
  3. SelectKey was not correctly utilized: When using selectKey, ensure to call selectKey before inserting data to obtain the generated primary key value, otherwise, you will not be able to retrieve the primary key value correctly.<\/li>\n
  4. Conflict in primary key generation strategies: Sometimes, different primary key generation strategies may result in selectKey being ineffective, such as having both automatic primary key generation and manually specifying a primary key configured at the same time, which can cause the selectKey to fail.<\/li>\n
  5. Database connection error: If there is an issue with the database connection, it may prevent the selectKey from executing properly, resulting in the inability to retrieve the generated primary key value.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
