數據庫批量更新的坑

 

若一個sql中通過分號分割(或包含)了多個獨立sql

修改數據庫連接配置：&allowMultiQueries=true

官方文檔：

allowMultiQueries
Allow the use of ';' to delimit multiple queries during one statement (true/false), defaults to 'false', and does not affect the addBatch() and executeBatch() methods, which instead rely on rewriteBatchStatements.
Default: false
Since version: 3.1.1
