I'm having a lot of trouble inserting text stored in a var into a table. Check out my code:
function updateTable(){
var text = "finally";
db.transaction(
function(transaction) {
transaction.executeSql('INSERT INTO Comentario (ComentarioCirc1, ComentarioCirc2) VALUES (text, "2")');
}
);
}
I've tried a lot of solutions but nothing worked. It should be so simple to do, what am I doing wrong? No data is inserted in the table and no error messages are shown also,
to fix your query you need to add value of text variable, like this:
transaction.executeSql('INSERT INTO Comentario (ComentarioCirc1, ComentarioCirc2) VALUES ("' + text + '", "2")');
but what you really should do is use parameterized SQL, like this:
transaction.executeSql('INSERT INTO Comentario (ComentarioCirc1, ComentarioCirc2) VALUES (?, "2")', [text]);
and if you want to know whether query succeeded or not you should pass success and error calbacks as third and fourth argument of executeSql.
I'd also suggest befriending webdatabase specification as it will answer a lot of other questions you will likely have ;)

Using ASP.Net core 3.0. my Database query works - I can get the result set (records), but how to pass/get the output parameter? Also would like to know if there's a way to get the return value.
I tried using different ways to call the SQL query and the only one I was able to get working was FromSqlInterpolated, but open to different methods.
This code works for me, but I want to pass an additional parameter that can get populated as an output parameter (which is working when I test it by calling the stored proc from within SQL Server).
var result = _context.Users
.FromSqlInterpolated($"EXEC mystoredproc {user.Username} ").AsEnumerable().FirstOrDefault();
I tried creating a variable before the call
string out1 = null;
And then including that in the call but I can't figure out the syntax and I'm not sure if it's supported with this method.
var result = _context.Users
.FromSqlInterpolated($"EXEC mystoredproc {user.Username}, OUTPUT {out1}").AsEnumerable().FirstOrDefault();
Console.WriteLine(out1);
Hoping someone can point me in the right direction - would like to know both how to use the output parameter and how to get the return value, not just the record set. Thank you.
The answer accepted does not seem to work for me.
However I finally manage to have the OUTPUT parameter work by using the following code
var p0 = new SqlParameter("#userName", {user.Username});
var p1 = new SqlParameter("#out1", System.Data.SqlDbType.NVarChar, 20) { Direction = System.Data.ParameterDirection.Output };
string out1 = null;
var result = _context.Users
.FromSqlRaw($"EXEC mystoredproc #userName, #out1 OUTPUT ", p0, p1).AsEnumerable().FirstOrDefault();
Console.WriteLine(p1.Value); // Contains the new value of the p1 parameter
Just a litte warning, the p1 value property will be changed only when the request will be executed (by an AsEnumerable, Load() or anything that forces the Sql execution)
I want to display data from Parse in a list from GamesScores class using Container in Codename One, this is what I've tried so far and it's not showing anything nor giving any errors:
Container container = findListCont();
container.setLayout(BoxLayout.y());
container.setScrollableY(true);
ParseQuery<ParseObject> query = ParseQuery.getQuery("GameScore");
List<ParseObject> results = (List<ParseObject>) query.find();
System.out.println("Size: " + results.size());
container.addComponent(results, f);
Please help me out, I'm a new in Codename One. If there tutorials on it, please share or anything to help me achieve the desired results.
I'm actually shocked this isn't failing. You are using the add constraint to place the object result as a constraint and you add the form object into the container...
You need to loop over the results and convert them to components to add into the layout. It also seems that you are using the old GUI builder which I would recommend against.
Generally something like this rough pseudo code should work assuming you are using a box Y layout:
for(ParseObject o : results) {
MultiButton mb = new MultiButton(o.getDisplayValue());
f.add(mb);
}
f.revalidate();
http://example.com/api/transfer/transfers/code/456/code/234
When using $this->get('code') on a url like above I expect the REST library to return an array or a list of the codes.
Instead it returns the last one.
Is there a way to return both values in a list, or is there another recommandation for formating the URL.
Thank you
I know it has been long since you posted the question. However it could help other people looking for the same thing.
Assuming that transfer is your controller and transfers is the function, another way to format your url could be:
http://example.com/api/transfer/transfers?code[]=456&code[]=234
This was you perform $this->get('code') you'll get an array back.
If you are creating the url via code then you may use http_build_query(). It handles the necessary escaping. It means it will replace [ for %5B and ] for %5D, in this case.
The code would be like:
$codes = array(456, 234);
$query = http_build_query(array('code' => $data));
$url = 'http://example.com/api/transfer/transfers?' . $query;
I've been searching for hours but I couldn't find an answer to my question: I've set up a ListGrid similar to the one shown here (Link). Right now I am using a XML-File as data source (default rows) just like in the example. It is also possible to add and delete rows to/from the grid.
Therefore I would like to store every user's data from the grid in a data store (Google Datastore). So I need to read all the rows of the current user as Strings. What would be a good way to do that? I already tried the following, but without success:
ListGrid componentsGrid = new ListGrid();
componentsGrid.setWidth(500);
componentsGrid.setHeight(224);
componentsGrid.setCellHeight(22);
componentsGrid.setDataSource(ComponentsXmlDS.getInstance());
componentsGrid.setAutoFetchData(true);
componentsGrid.setCanEdit(true);
componentsGrid.setModalEditing(true);
componentsGrid.setEditEvent(ListGridEditEvent.CLICK);
componentsGrid.setListEndEditAction(RowEndEditAction.NEXT);
componentsGrid.setAutoSaveEdits(false);
layout.addMember(componentsGrid);
//First try
componentsGrid.fetchData();
logger.log(Level.INFO, "Components: "+ componentsGrid.getResultSet().get(0).getAttribute("componentType"));
//Second try
logger.log(Level.INFO, "Components: "+ componentsGrid.getAllFields());
// Third try
logger.log(Level.INFO, "Components: "+ componentsGrid.getRecords());
Anyone having a hint? Help is greatly appreciated.
If I understand well your requirement you want to read all the rows of the grid and store their data in a db.
I think you can use:
getRecordList() which *Return the underlying data of this DataBoundComponent as a RecordList.
You will be able to iterate inside this list, extract the attribute value you want for every record and store these data in your db.
Or use the getRecords() method as you said and iterate in the array of ListGridRecord obtained.
To iterate through your RecordList you have to transform it to an array, for example with a lot of dummy objects and methods:
RecordList data = MyGrid.getRecordList();
for(Record record : data.toArray()){
MyDataObject obj = new MyDataObject()
obj.setId(record.getAttribute("thId"));
obj.setOne(record.getAttribute("anAttribute"));
obj.setTwo(record.getAttribute("anotherAttribute"));
obj.StoreToDb();
}
HI..
I have a database created and having a table inside it..
now when i am inserting a value in my table it doesnot work...
And please tell me how to see the error if occurs in the eclipse plug in . I am very new to blackberry.
now the snippet code for inserting the value is
Database d;
URI myUri = URI.create("file:///SDCard/Databases/SQLite_Guide/", "Mynewdatabase1.db");
d= DatabaseFactory.create(myUri);
d.close;
Statement s1=d.createStatement("INSERT INTO People(Name,Age)VALUES ('uttam',23)");
s1.prepare();
s1.execute();
s1.close();
d.close();
You're closing the data base before calling createStatement? That isn't going to work. Is this the actual code, because the first you're missing the parens on the first call: d.close;
