oracle mybatis 批量插入遇到的问题

1、这是一个很蛋疼的问题，用<insert>的话会一直报sql语法错误，我这里改用<update>测试OK，用<select>貌似也行

2、批量插入带oracle序列递增遇到的错误：java.sql.SQLSyntaxErrorException: ORA-02287: 此处不允许序号

查资料说有很多限制

Restrictions on Sequence Values You cannot use CURRVAL and NEXTVAL in the
following constructs:
■ A subquery in a DELETE, SELECT, or UPDATE statement
■ A query of a view or of a materialized view
■ A SELECT statement with the DISTINCT operator
■ A SELECT statement with a GROUP BY clause or ORDER BY clause
■ A SELECT statement that is combined with another SELECT statement with the
UNION, INTERSECT, or MINUS set operator
■ The WHERE clause of a SELECT statement
■ The DEFAULT value of a column in a CREATE TABLE or ALTER TABLE statement
■ The condition of a CHECK constrain

在mybatis <foreach>外边再套一层解决
