业务层调用数据库时遇到sql异常

java.sql.SQLException: Column count doesn't match value count at row 1
at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1073)
at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3597)
at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3529)
at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1990)

错误原因：sql语句里面列的数目与后面的值得数目不一致比如insert into 表名 (field1,field2,field3) values('a','b')这样前面的是三列，后面却只有二个值，这就会出现这个错误的。

    错误原因数值溢出，mysql中数据库涉及student表sex为bit(1)，而实际传值为1或者2，数值溢出
