ColdFusion: Trying to query database in CFScript

9
votes

My boss wants me to use cfscript instead of tags for database interaction. Does anybody know of any good tutorials? I bought the Adobe ColdFusion application development book, vol 2. But it does not have much on scripting. I did google and found this site, but it did not explain much.

Does any body know of any good tutorials on accessing the data base in CFScript?

Basically I have to convert the following to using CFScript:

<cfquery name="drafts" datasource="ICEchat">
    SELECT * from Messages where IsTemp=1 and LinkA=#FORM.LinkA# and LinkB=#FORM.LinkA#
</cfquery>
<cfif drafts.recordcount GT '0'>
    <cfquery name="Attachments" datasource="ICEchat">
        SELECT * FROM Attachments where id=2
    </cfquery>
    { Message:"<cfoutput query="drafts">#Message#</cfoutput>", Attachments:[<cfoutput query="attachments">
        "#url#"<cfif attachments.currentRow LT attachments.recordcount>,</cfif>
    </cfoutput>]}
<cfelse>
    <cfquery name="addrecord" datasource="ICEchat">
        INSERT INTO Messages 
        VALUES(1,1,' ',1)
    </cfquery>
    { Message:"NA", Attachments:[]}
</cfif>

You're right, Jake, that it was pretty awful. But it took me less than a minute to fix it. Which is more constructive: Complaining or fixing it? - Adam Tuttle
Well, here is the official documentation. help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/… - Jason Dean
@AdamTuttle you're right, of course. More virtue to be found in overlooking such things. - Jake Feasel
Hi,thank you for the link, Guess I need to look at my typing more, - Ted pottel
Which version of ColdFusion. The current version, 2016, has queryExecute() which a very clean syntax. - James A Mohler

From the 4th link on google for "cfscript query tutorial":

<CFSCRIPT>
    myQry = new Query(); // new query object     
    myQry.setSQL("select bookid, title, genre from app.books where bookid = :bookid"); //set query
    myQry.addParam(name="bookid",value="5",CFSQLTYPE="CF_SQL_INTEGER"); // add query param
    qryRes = myQry.execute(); // execute query
    writedump(qryRes.getResult().recordcount, true); // get resultcount
    writedump(qryRes.getResult(), false); // dump result
    writeoutput('<BR>');
</CFSCRIPT>

That ought to tell you everything you need to know.

Also, you really should not be creating JSON manually, no matter how simple it is. Use serializeJson().

Didn't test this, but this should do it.

<cfscript>
   local.drafts = new Query();
   local.drafts.setDatasource("ICEchat");
   local.drafts.addParam(name="linkA", value="#form.linkA#", cfsqltype="CF_SQL_VARCHAR");
   local.drafts.addParam(name="linkB", value="#form.linkB#", cfsqltype="CF_SQL_VARCHAR");
   local.drafts.setSQL("SELECT * from Messages where IsTemp=1 and LinkA = :linkA and LinkB = :linkA");
   local.drafts.execute().getResult();

   if (local.drafts.recordcount GT 0) {
      local.attachments = new Query();
      local.attachments.setDatasource("ICEchat");
      local.attachments.setSQL("SELECT * FROM Attachments where id=2");
      local.attachments.execute().getResult();
      WriteOutput("{ Message: ");
      for (i=1; i LTE local.drafts.recordcount; i=i+1) {
         WriteOutput(local.drafts.message[i]);
      }
      WriteOutput(", Attachments: ");
      for (i=1; i LTE local.attachments.recordcount; i=i+1) {
         WriteOutput(local.drafts.url[i]);
         if (i LT local.attachments.recordcount) {
            WriteOutput(", ");
         }
      }
      WriteOutput("}");
   } else {
      local.q = new Query();
      local.q.setDatasource("ICEchat");
      local.q.setSQL("INSERT INTO Messages VALUES(1,1,' ',1)");
      local.q.execute();
      WriteOutput("{ Message:"NA", Attachments:[]}");
   }
</cfscript>

I have been searching for a solution for the same error. I get not defined errors or construct errors. Have been chatting with Ray Camden for the past day, but everything he has suggested is not doing what I need either. I have been working on a website conversion from the standard CF tags to cfscript.

Ray suggested that the .execute(); is what pulls the recordcount and suggested this is all was needed: x=queryExecute(); would fetch the recordcount, with (x) being the query. He suggested not to use getPrefix(); but I read that the .getPrefix(); is what pulls the recordcount. He is experienced I am sure you know Ray Camden, but I keep getting the same error no matter what I try doing inside of my code.
