JSP ORACLE table 创建错误

Question

我正在开发一个基于 JSP web 的应用程序，它应该与 OJDBC 一起工作。这里 TABLE 名称将由用户在 FORM 中提供，table 创建将通过与 OJDBC 链接的 .jsp 文件进行处理。但是我在 CREATETB.jsp

上收到以下错误

输入异常报告

说明服务器遇到内部错误，无法完成此请求。 org.apache.jasper.JasperException: 处理 JSP 页 /createtb.jsp 第 12 行时发生异常

Answer 1

看看：enter link description here 要创建 table，您不能使用：

Statement st= con.createStatement(); 
ResultSet rs;
rs = st.executeQuery(sql);

因为这是 select 查询。你宁愿使用：

stmt = conn.createStatement();
String sql = "CREATE TABLE "+table_name+" (...)"; 
stmt.executeUpdate(sql);
