Question

我试图使用JdbcTemplate插入员工。但我得到Invalid Column Type例外。知道可能是什么问题吗？

Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [insert into employees (employee_id,first_name,last_name,email,hire_date,job_id) values (?,?,?,?,?,?))]; SQL state [null]; error code [17004]; Invalid column type; nested exception is java.sql.SQLException: Invalid column type

Answer 1

从the Spring docs开始，第三个参数必须是＆＃34;参数的SQL类型（来自java.sql.Types的常量）＆＃34;但是你提供了new EmployeeMapper()。

Answer 2

对我来说，当我尝试在timestamp列上设置null值时，会出现此问题。我更改了值timestamp（0）。这对我来说似乎是一个驱动问题。我使用的是oracle 10g / ojdbc14.jar / oracle.jdbc.OracleDriver

Answer 3

尝试删除新的EmployeeMapper（）

jdbcTemplate.update(sql, new Object[] {Integer.valueOf(2007),"AAAAAAA","BBBBBB","abc@gmail.com",new java.sql.Date(date.getTime()),"ST_MAN"});

Spring：SQL state [null];错误代码[17004];列类型无效
