填充表时两个相互依赖的查询

发布于 2024-08-24 06:53:12 字数 421 浏览 4 评论 0原文

我有 2 个疑问。一种是填充填充下拉列表的数据集，另一种填充表行的其余文本框。我想知道如何填充整个下拉列表，然后使 selectedvalue 成为其他查询中的值？

例如 -

dataset query = select hobby from hobbies
other query - select name, dob, address, hobby from employee

现在表看起来像这样 -

Name DOB         Address       Hobby
Sam  01/10/1988  111 main st   Dropdownlist(n number of records)

现在在下拉列表中，我希望将员工表中的爱好填充的所有爱好作为所选值。

原文

I have 2 queries. One is populating a dataset that populates the dropdownlist and the other populates rest of the textboxes of a table row. i want to know how can i fill the entire dropdownlist and then make selectedvalue the value from the other query?

e.g -

dataset query = select hobby from hobbies
other query - select name, dob, address, hobby from employee

now the table looks like this -

Name DOB         Address       Hobby
Sam  01/10/1988  111 main st   Dropdownlist(n number of records)

Now in the dropdownlist I want all the hobbies populated with the hobby in the employee table to be the selected value.

不确定我是否理解，但我会尝试使用一些伪代码，

  ## fetch hobbies and employees from db
  dataset hobbies = select hobby from hobbies;
  dataset employees = select name, dob, address, hobby from employee;

  ## loop through all employees
  foreach employee in employees{

    print employee->name;
    print employee->dob;
    print employee->adress;

    ## second loop to print hobbies dropdownlist for each emplyee
    print "<select>";
    foreach hobby in hobbies{
      boolean is_selected = (employee->hobby == hobby);
      print "<option value=\"".hobby."\" selected=\"".is_selected."\">".hobby."</option>";
    }
    print "</select>";
}

这不是正确的 html 或任何内容，只是证明概念的伪代码。

Not sure if i understood, but ill try with some pseudo-code

  ## fetch hobbies and employees from db
  dataset hobbies = select hobby from hobbies;
  dataset employees = select name, dob, address, hobby from employee;

  ## loop through all employees
  foreach employee in employees{

    print employee->name;
    print employee->dob;
    print employee->adress;

    ## second loop to print hobbies dropdownlist for each emplyee
    print "<select>";
    foreach hobby in hobbies{
      boolean is_selected = (employee->hobby == hobby);
      print "<option value=\"".hobby."\" selected=\"".is_selected."\">".hobby."</option>";
    }
    print "</select>";
}

This is not correct html or anything, just a pseudocode to proof concept.
