Basically i have few tables in MySql and im trying to create an array mixed with data from diferrent tables. I'm using AJAX to get the data from CFC. I've tried using different ajax requests to get the data from different tables but thats making my code very long.

 

First example table - user_info_tb

--------------------------------------

USER_ID | FULL_NAME

----------------------------------------

      2              Jack

      3             John

      4             Jamie

 

Second example table - post_tb

 

--------------------------------------

POST_ID | POSTED BY (USER_ID FROM THE FIRST TABLE)| TEXT |

--------------------------------------------------------------------------------------------------

      1              2                                                                                        Hi

      2              3                                                                                        Hello

      3              4                                                                                        Good Morning

I shall call the queries, respectively Q1 and Q2. 

Then you could do something like

<!--- Remember that in ColdFusion array indices generally start from 1 --->
<cfset myArray=arrayNew(2)>
<cfloop from="1" to="3" index="i"> 
<cfset myArray[i][1]=Q1.fullname[i]>
<cfset myArray[i][2]=Q2.text[i]> 
</cfloop>

Simplyfy the data extract by using a join to get one row per user then loop and add to the array

 

<cfquery name="q" datasource="#application.setting.DSN.Source#">
select u.full_name, p.text
   from user_info_tb u
        join post_tb p on p.posted_by = u.user_id
</cfquery>

<cfscript>
myArray=arrayNew(2);
for (row in q) {
    myArray.append([row.full_name, row.text]);
}

writeDump(myArray);
</cfscript>
