Question

我在eclipse中执行了一个代码，我的目标是在postgres数据库中调用一个存储过程。我尝试从servlet传递的值并得到此错误：＆＃34;偏移量为1的格式错误的函数或过程转义语法。＆＃34;

所以现在我尝试对这些值进行硬编码。仍然是同样的问题。什么是抵消？请帮我解决错误。我已经检查了字段的顺序和数据类型。它们是正确的。

public int  dispCustomer3(Cust cc){
    con=dbCon.getConnection();
    //PreparedStatement ps3=null;
    System.out.println("inside update function ");
    CallableStatement callableStatement =null;
    try {
        callableStatement=con.prepareCall("{SELECT fn_UpdateCustomer(37, 'Test_Customer56','Test_Customer56','Requirement','Customer_Location',NULL,2,2,NULL,'Customer_Contact_Info','Account_Contact_Info','01-02-2016','01-04-2016',5,'Comments',1,2);}");
        /*callableStatement.setInt(1,cc.getCustId());
        callableStatement.setString(2,cc.getShortName());
        callableStatement.setString(3,cc.getStatus_name() );
        callableStatement.setString(4,cc.getRequirement());
        callableStatement.setString(5,cc.getCustomer_location());
        callableStatement.setInt(6,cc.getDemo_location_type_id());
        callableStatement.setInt(7, cc.getDeployment_type_id());
        callableStatement.setInt(8, cc.getRequested_by_id());
        callableStatement.setInt(9, cc.getPilot_resource_id());
        callableStatement.setString(10, cc.getCustomer_contact_info());
        callableStatement.setString(11, cc.getAccount_contact_info());
        callableStatement.setDate(12, cc.getDemo_planned_on());
        callableStatement.setDate(13, cc.getDemo_actual_on());
        callableStatement.setInt(14, cc.getStatus_id());
        callableStatement.setString(15, cc.getComments());*/
        callableStatement.registerOutParameter(1, java.sql.Types.INTEGER);
        callableStatement.executeUpdate();



    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }finally{dbCon.closeConnection(con);}
    return 1;



}
}

Answer 1

使用CallableStatement时，您应该CALL您的程序，而不是SELECT。类似的东西：

callableStatement=con.prepareCall("{CALL fn_UpdateCustomer(37, 'Test_Customer56','Test_Customer56','Requirement','Customer_Location',NULL,2,2,NULL,'Customer_Contact_Info','Account_Contact_Info','01-02-2016','01-04-2016',5,'Comments',1,2)}");

您收到的错误Malformed function or procedure escape syntax at offset 1是指SELECT关键字。

偏移量为1的格式错误的函数或过程转义语法
