Question

我有一个包含列名的表（FirstName，LastName，Age，Profession，Salary）。我有3个搜索框即（FirstName，LastName，Salary）。

如果我输入名称，请说＆＃34; xyz＆＃34;在FirstName文本框中，然后是值＆＃34; xyz＆＃34;应该只在FirstName列中搜索。同样，如果我输入值＆＃34; abcd＆＃34;在姓氏搜索框中然后是值＆＃34; abcd＆＃34;应该只在lastname列中搜索。

如何使用jquery数据表完成上述功能。

示例代码 //搜索文本框

<html><body>
    <div>
           <table width='100%'>
         <tr>
          <td >First Name:</td>    <td id='fname'><input type= "text"></td>
         </tr>

          <tr ><td >Last name:</td>      
             <td id="lname"><input type= "text"></td>
          </tr>

          <tr ><td >Age:</td>      
             <td id="age"><input type= "text"></td>
          </tr>

          <tr ><td >Profession:</td>      
               <td id='prof'><input type= "text"></td>
          </tr>

          <tr ><td >Salary:</td>   
               <td id='sal'><input type= "text"></td>
          </tr>
           </table>
    </div>

//表

        <thead>
            <tr>

// Jquerycode

 $(example).dataTable().
                    columnFilter({aoColumns:[
                            { sSelector: "#fname"},
                            { sSelector: "#lname" },
                            null
                            null,
                            {sSelector: "#sal"},
                       ]}            
             );

Answer 1

column().search()

WITH a
as
(
    select colid,coldate
    from cal_3month
    group by colid,coldate
),
b 
as
(
    select colid,SUM(colvalue) as sumvalue
    from cal_3month td
    WHERE extract('month' from td.coldate) between extract('month' from now() - interval '3 month')  and extract('month' from now() - interval '1 month')  
    and extract('year' from td.coldate) = extract('year' from now()) --and td.st_exchng = 'NSE'
    group by td.coldate,td.colid
    order by td.coldate desc

,
c
as
(
    SELECT a.colid,string_agg((extract('year' from a.coldate)::varchar||extract('month' from a.coldate)::varchar)::varchar,',') as dt,
