The renewal maintenance has officially ended for Progress iMacros effective November 20, 2023 and all versions of iMacros are now considered EOL (End-of-Life). The iMacros products will no longer be supported by Progress (aside from customer license issues), and these forums will also no longer be moderated from the Progress side.

Thank you again for your business and support.

parameterized sqlite query not working

Post by ravi_npatty » Mon Apr 17, 2017 6:37 pm

I express my sincere thanks to blueX for providing nice library for keeping things simple through this post
http://forum.imacros.net/viewtopic.php? ... end#p73568

I am able to store my data into sqlite with simple query. When I try to use parameterized query, it fails with error message:

[Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [mozIStorageStatement.execute]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: resource://gre/modules/RemoteAddonsParent.jsm line 780 > eval :: iimSqlite.prototype.exec :: line 89" data: no], line 89 (Error code: -991)

My code is here:

Code: Select all

	var db=new iimSqlite("test_v1.sqlite");
	//alert("file ok");
	db.exec('create table if not exists test ([ID] text primary key,[col 1] text,[col 2] number,[col 3] text);');
	//alert("create table ok");
	sql='insert or replace into test ([ID],[col 1],[col 3],[col 2]) values(:id, :col1, :col3, :col2);';
	param=[{name:"id",value:"255"},{name:"col1",value:"col1 text"},{name:"col2",value:458752},{name:"col3",value:"col3 text"},]
	alert(sql);
	db.exec(sql,param);
	alert("insert ok");
	db.close();
Somebody please help me in getting this working.
Thanks.

Re: parameterized sqlite query not working (solved)

I have solved this issue. There was problem in binding parameter inside the library (iimext.js). I am posting the modified code here so that people need not solve it again.
I have commented old code for reference purpose.

A small change in approach now.
In earlier code, parameter was passed as param=[{name:"paramname1",value:"paramvalue1"},{name:"paramname2",value:"paramvalue2"},...]
In my modified code, I use param={paramname1:paramvalue1,paramname2:paramvalue2,...}

Similar change is required in query function also.

My code is here

Code: Select all

	iimSqlite.prototype.exec = function(sql, params) 
	{
		  //this.dbConn.executeSimpleSQL(sql);
		var stmt = this.dbConn.createStatement(sql);
		if (typeof(params) =="object") 
		{
			var bp;
			var _params = stmt.newBindingParamsArray();
			if(typeof(params.length)=="undefined")
			{				
				bp = _params.newBindingParams();  
				for(var prm in params) bp.bindByName(prm, params[prm]); 
				
				_params.addParams(bp); 	
			}
			else
			{
				
				alert("error");
			}

Hum..., nice...!, and Thanks for sharing, and you've nicely updated the original Thread as well... :D

But you should mention in which Environment you encountered the Pb and tested your Solution, as new Versions of iMacros or of FF regularly break some Functionality... (And this is Required Info anyway to include in your Post when you open a new Thread or post for the first time in some existing Thread for me to react...)
=> Probable FCI(s) (April 2017):
- iMacros for FF v9.0.3, FF52, OS...?, + sqlite v3.18.0. (v9.0.3 = Latest (Version for iMacros for FF) but "unstable"...)
- iMacros for FF v8.9.7, FF52, OS...?, + sqlite v3.18.0. (v8.9.7 = Stable...)
- (F)CI(M) = (Full) Config Info (Missing): iMacros + Browser + OS (+ all 3 Versions + 'Free'/'PE'/'Trial').
- FCI not mentioned: I don't even read the Qt...! (or only to catch Spam!)
- Script & URL help a lot for more "educated" Help...

Re: parameterized sqlite query not working

Sorry for not posting my FCI.

My FCI was
iMacros for FF v8.9.7, FF52, Linux .
Not sure about sqlite version since it uses sqlite engine of firefox. No external database connection can be made. Version might be as you guessed sqlite v3.18.0

Since I knew the issue was of some logic, I skipped FCI. Anyway I should have given that. No excuse. Sorry.
