Caused by: java.sql.SQLException: Operand should contain 1 column(s

Caused by: java.sql.SQLException: Operand should contain 1 column(s)这个错误是由于写MyBatis语法错误引起的。具体来说，错误出现在使用MyBatis进行批量插入MySQL时的XML配置中。在这段配置中，insert语句中的foreach标签用于遍历一个Java List，并将其元素插入到数据库中。然而，错误的根本原因是在插入语句中的某个地方，出现了一个不应该存在的多个列的操作数。这可能是由于在foreach标签中的SQL语句中使用了错误的语法，导致在生成SQL时出现了错误的列数。为了解决这个问题，需要检查insert语句中的foreach标签的SQL语句，并确保其中的列操作数与数据库表的列数匹配。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
