I have such objects in ScriptDb,
[{a:1,b:2,c:3},{a:0,b:0}]
How do I query object without key c?
It seems the only way is to query all object using db.query({}), then use something like "typeof result.c == 'undefined'".
Is there a way to do it in ScriptDb?
Thanks.
You can use that to get records without c:
var db = ScriptDb.getMyDb();
var result = db.query({c: db.not(db.anyValue())});
while (result.hasNext()) {
var current = result.next();
Logger.log ("a= "+current.a+", c="+current.c);
}
The ones with c:
var result = db.query({c: db.anyValue()});
These functions (not, anyValue...) are documented in Class ScriptDbInstance

Using shared preferences to save an arrayListOf in my app. Im converting the array to a hashset and saving it but when I load it I am unable to convert it back to an arrayListOf. I have tried toTypedArray() and toArray() but neither solve the problem. Getting the error below.
Required:
kotlin.collections.ArrayList /* = java.util.ArrayList */
Found:
(Mutable)Set<String!>?
Using the following to try and load the hashet and convert it.
var sharedPreferences = getSharedPreferences(SHARED_PREFS, MODE_PRIVATE)
var places = arrayListOf<String>()
var loadSet = sharedPreferences.getStringSet("key", null)
places = loadSet
go.setOnClickListener{
thread {
val place = newLocation.text.toString()
var stringCounter = counter.toString()
if(place !in places){
places.add(place)
//editor.putStringSet("key", places)
//editor.commit()
var sharedPreferences = getSharedPreferences(SHARED_PREFS, MODE_PRIVATE)
var editor = sharedPreferences.edit()
set.add(place)
editor.putStringSet("key", set);
editor.commit();
Log.d("set", set.toString())
var loadSet = sharedPreferences.getStringSet("key", HashSet<String>())?.toList()
Log.d("load", loadSet.toString())
places = loadSet as ArrayList<String>
}
arrayListOf isn’t a type. It’s a function. The type is ArrayList, but it’s more typical to only need the more abstract List or MutableList, depending on what you’re doing with it. For those you can use set.toList() or set.toMutableList().
If you have an existing ArrayList or MutableList, you could also do list.addAll(set).
I have a Google spreadsheet that I'm trying to remove the word "woo" within a range of cells
So far I've managed to loop through the results and log the results, however I haven't figured how to update that information in the spreadsheet itself.
Any guidance would be welcomed
Thank you
function myFunction () {
var ss = SpreadsheetApp.getActiveSheet().getRange('B:B')
var data = ss.getValues();
for (var i = 0; i < data.length; i++) {
var text = data[i].toString();
var finaltext = text.replace(/woo/g, "");
data[i] = finaltext;
Logger.log(data[i]);
}
}
Use setValues()
Notes:
Usually ss is used as a shorthand for spreadsheet, as it's used on the code for a range it's better to use range as a variable name.
setValues() returns a 2D array, so data[i] returns an array of row values rather than a cell value. To get/set cell values, use data[i][0] notation.
Considering the above replace
var ss = SpreadsheetApp.getActiveSheet().getRange('B:B')
by
var range = SpreadsheetApp.getActiveSheet().getRange('B:B')
then add the following line after the for block.
range.setValues(data);
Regarding text var declaration, replace
var text = data[i].toString();
to
var text = data[i][0].toString();
Using open ended references like B:B could lead to problems. To avoid them be sure to keep the sheet rows at minimum or better instead of using an open ended reference use something like B1:B10.
var ss = SpreadsheetApp.openByUrl('https://docs.google.com/spreadsheets/d/1Ow_rhF3sibKL3OAQRXpK6LLZDjMOhW-5DKyWWiN5iZg/edit#gid=638513192');
var data = SpreadsheetApp.setActiveSheet(ss.getSheetByName('Graficos'));
Logger.log(SpreadsheetApp.getActiveSpreadsheet());
var ergo = data.getRange(3,2,4,1);//B3:B6 '
My guess to access the elements was to call var i = ergo[0]; but it didn't work. Do I have to declare ergo using a different syntax?
You need to use getValues() on the range, which will return a 2-dimensional array.
var ergo = data.getRange(3,2,4,1).getValues();
Also, you're not coding efficiently as you're essentially duplicating actions in your first two lines. Take a look at this refactoring:
function test() {
var ss = SpreadsheetApp.openByUrl('https://docs.google.com/spreadsheets/d/1Ow_rhF3sibKL3OAQRXpK6LLZDjMOhW-5DKyWWiN5iZg/edit#gid=638513192');
var data = ss.getSheetByName('Graficos');
ss.setActiveSheet(data); // There doesn't seem to be a need to do this, so maybe delete this line
var ergo = data.getRange(3,2,4,1).getValues(); //B3:B6
}
I have used QueryMultiple before for handling multiple result sets, but I knew the exact number of result sets being returned. In this case, when I call a stored proc with QueryMultiple, the number of result sets returned varies. Is it possible to handle this in PetaPoco or another orm such as Dapper?
Dapper's QueryMultiple method returns a GridReader; a GridReader has a .IsConsumed property that should change to true when you've read all the available result sets, so that might work:
using(var reader = conn.QueryMultiple(...)) {
do {
var data = reader.Read<...>().AsList();
// ...
} while(!reader.IsConsumed);
}
Alternatively, Dapper has an ExecuteReader method that just does the "pack the parameters and invoke step", and a GetTypeDeserializer method that exposes just the "materialize a row into an object" code, so you could manually combine those, i.e.:
using(var reader = conn.ExecuteReader(...)) {
do {
var parser = SqlMapper.GetTypeDeserializer(...);
while(reader.Read()) {
var obj = parser(reader);
// ...
}
} while(reader.NextResult());
}
(I don't know much about petapoco, sorry)
How to map the OLE DB source SQL command query parameters with variables using EzAPI ?
Basically I need to do something like below.
Thanks in advance.
Here is how I had to do it for SSIS 2012. I had to find the GUID of the variable in question and set it that way.
EzOleDbSource source = new EzOleDbSource(this);
source.Connection = sourceconnection;
source.SqlCommand = sourcecomannd;
source.AccessMode = AccessMode.AM_SQLCOMMAND;
source.SetComponentProperty("ParameterMapping", "\"Parameter0:Input\",{C2BCD5B0-1FDB-4A74-8418-EEF9C1D19AC3};");
To get the GUID you can query the Variables in the EZPackage object.
Application a = new Application();
var package = a.LoadPackage(packagelocation, null);
var ezpackage = new EzPackage(package);
var firstOrDefault = ezpackage.Variables.OfType<Microsoft.SqlServer.Dts.Runtime.Variable>()
.AsQueryable()
.FirstOrDefault(x => x.Name.Equals("MyParameter"));
if (firstOrDefault != null)
{
var guid =
firstOrDefault.ID;
}
I have accepted Geek's answer because it is the real answer for my question. But I found instead of mapping variables to parameters we can use variables directly in the query. For example: exec your_sp_name "#[User::your_variable_name]"
UPDATE : Above method is not working.
Use the the accepted answer method. To take the GUID of the variable, I used the follwing method.
string guid = string.Empty;
foreach (var x in this.Variables)
{
if (x.Name == "cdc_capture_log_id")
{
guid = x.ID;
}
}
Where this = EzPackage. Same as above.
