Question

我有一个更新方法来根据特定字段更新表的内容，我得到以下异常。

代码是：

public void updateTaxoActive(String oldDesc, String description) {
    Logger.getLogger(TypeCategoryJDBCTemplate.class.getName()).log(Level.INFO, "old taxonomy code is {0} new description is {1}", new Object[]{oldDesc, description});
    String sql = "update product.typecategory set taxonomydescription = ? where taxonomydescription = ?";
    jdbcTemplateObject.update(sql, new Object[]{description,oldDesc},new TypeCategoryMapper());
}

例外是：

Exception in thread "AWT-EventQueue-0" org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [update product.typecategory set taxonomydescription = ? where taxonomydescription = ?]; nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][1091][10824][4.13.127] Invalid data conversion: Parameter instance [Ljava.lang.Object;@1dc421 is invalid for the requested conversion.
