I am using the latest version of the MiniProfiler, everything is setup and working as I would expect. My only issue is that SqlParameters are not being displayed.
For example, I am running a stored procedure:-
var cmd = dbcon.CreateCommand();
cmd.CommandText = "USP_Admin_Subscription_List";
cmd.CommandType = CommandType.StoredProcedure;
// parameters
cmd.Parameters.Add(new SqlParameter("#UserRef", SqlDbType.NVarChar) { Value = customerRef });
When this executes I see the SQL in the MiniProfiler display but I do not see the Parameter #UserRef nor it's value.
Is this possible? It would be great to see the value so I can ensure the correct value is being passed.
I am using MVC 3
Any advice would be welcomed.
Cheers,
J
Old questions, but just in case anyone else is looking for the answer to this:
The sample code has:
// different RDBMS have different ways of declaring sql parameters - SQLite can understand inline sql parameters just fine
// by default, sql parameters won't be displayed
MiniProfiler.Settings.SqlFormatter = new StackExchange.Profiling.SqlFormatters.InlineFormatter();
You need to change it to:
MiniProfiler.Settings.SqlFormatter = new StackExchange.Profiling.SqlFormatters.SqlServerFormatter();
And your parameters will appear.

At one point using FromSqlRaw to call stored procedures worked for me. I did not change anything in the project but now calling any stored procedure using FromSqlRaw returns
The underlying reader doesn't have as many fields as expected
I removed the model from the project and performed a BUILD. Then added the model back with no luck. I reduced the model and stored procedure to return a single column, no luck.
I tried adding Microsoft.EntityFrameworkCore.Relational as a dependency, no luck. All my unit test that use FromSqlRaw to call a stored procedure return the same error and at one time they all worked.
I have received Windows updates but nothing I know about that would have affected EF Core. I have run through all internet problem solving I can find. I am starting to think I will need to use ADO as a work around but I do not want a work around when it worked for me at one point. Something changed on my machine but I am not sure what to cause this problem.
Here is my test method in case my code is messed up. It is very straight forward not much to mess up. I tried the "var" out of desperation.
[TestMethod]
public void WorkOrderBOMGridABS()
{
List<WorkOrderBOMGridABS> baseList = new List<WorkOrderBOMGridABS>();
using (WorkOrderDataContext context = new WorkOrderDataContext())
{
var param = new SqlParameter[] {
new SqlParameter() {
ParameterName = "#WorkOrderId",
SqlDbType = System.Data.SqlDbType.Int,
Direction = System.Data.ParameterDirection.Input,
Value = 38385
}
};
baseList = context.WorkOrderBOMGridABS.FromSqlRaw("[dbo].[WorkOrderBOMGridABS] #WorkOrderId", param).ToList();
//var results = context.WorkOrderBOMGridABS.FromSqlRaw("[dbo].[WorkOrderBOMGridABS] #WorkOrderId", param).ToList();
Assert.IsNotNull(baseList);
}
}
I was using an old table to get the Unit Of Measure value that had an integer ID value. I switched it to use a new table with a VARCHAR ID value. Making this change to the stored proc and model code allowed the FromRawSql to work. Not sure why because while the integer ID value was getting an integer, either 0 or number other than 0, it was a valid value for the model. Any error message I received did not mention this UnitId field. It was a pain but I am glad it is resolved. At least until the next error I run into that much is guaranteed.
Question: I need to manually call an object listener event (e.g. key pressed) to trigger a function. I used to do it in Access but haven't found the documentation for it in LibreOffice Base.
Context: Having retired from software development 7 years ago, I am doing a favour for a friend by building a database in LibreOffice Base. Previously experienced in Access - but more with Oracle, PL/SQL, APEX, etc! I am struggling a little in getting it to do what I know can be done!
Here is the code I've tried so far.
Sub CauseKeyPressedEventToBeFired
oDoc = ThisComponent
oController = oDoc.getCurrentController()
oVC = oController.getViewCursor()
oForm = oDoc.getDrawpage().getForms().getByName("Form")
oTextBox = oForm.getByName("Text Box 1")
oControlView = oController.getControl(oTextBox)
oControlView.setFocus()
Dim oEvent As New com.sun.star.awt.KeyEvent
oEvent.Source = oControlView
oEvent.KeyCode = com.sun.star.awt.Key.A
oControlView.keyPressed(oEvent)
End Sub
However, it doesn't seem to work on my system (LibreOffice 6.4.3.2 on Windows). I also found this post, but that code doesn't seem to work for me either.
I searched for com.sun.star.awt.XToolkitRobot, but it's not in the API documentation, perhaps because the functionality is not fully supported. Presumably, it can be obtained from com.sun.star.awt.Toolkit.
For more help, post a question on ask.libreoffice.org. I'd suggest explaining why you want to do this, because there may be a different kind of solution. Ratslinger has a lot of experience solving various database problems, and he'll probably direct you toward a simpler solution that doesn't involve this kind of event hacking.
a function (i.e. a procedure that returns a value)
Yes, that is what a function is. But "an object listener event" implies, correctly I think, that we're talking about the method of an object instead. That's what LibreOffice event listeners are in Python or Java, although in Basic, they're a little strange, using the object name as some kind of magic to determine what they apply to. Anyway, that's getting off track, because your question isn't about listening for events, but rather about triggering them.
EDIT:
The following Python code works. The problem with my earlier attempts was that oEvent.KeyChar needs to be set, and that doesn't seem to work in Basic. I can't imagine why, unless I am ignoring some obvious mistake in the Basic code.
def causeKeyPressedEventToBeFired(oEvent=None):
oDoc = XSCRIPTCONTEXT.getDocument()
oController = oDoc.getCurrentController()
oForm = oDoc.getDrawPage().getForms().getByName("Form")
oTextBox = oForm.getByName("Text Box 1")
oControlView = oController.getControl(oTextBox)
oControlView.setFocus()
oEvent = uno.createUnoStruct("com.sun.star.awt.KeyEvent")
oEvent.Source = oControlView
from com.sun.star.awt.Key import A
oEvent.KeyCode = A
oEvent.KeyChar = "a" # works in Python but strangely not in Basic
simulate_KeyPress(oEvent)
def simulate_KeyPress(oKeyEvent):
oDoc = XSCRIPTCONTEXT.getDocument()
oWindow = oDoc.CurrentController.Frame.getContainerWindow()
oKeyEvent.Source = oWindow
oToolkit = oWindow.getToolkit()
oToolkit.keyPress(oKeyEvent)
oToolkit.keyRelease(oKeyEvent)
EDIT 2:
Finally, here is working Basic code. In the earlier attempt, the type was wrong.
Sub CauseKeyPressedEventToBeFired
oDoc = ThisComponent
oController = oDoc.getCurrentController()
oForm = oDoc.getDrawpage().getForms().getByName("Form")
oTextBox = oForm.getByName("Text Box 1")
oControlView = oController.getControl(oTextBox)
oControlView.setFocus()
Dim oEvent As New com.sun.star.awt.KeyEvent
oEvent.KeyCode = com.sun.star.awt.Key.A
oEvent.KeyChar = CByte(97)
simulate_KeyPress(oEvent)
End Sub
Sub simulate_KeyPress(oKeyEvent As com.sun.star.awt.KeyEvent)
oWindow = ThisComponent.CurrentController.Frame.getContainerWindow()
oKeyEvent.Source = oWindow
oToolkit = oWindow.getToolkit()
oToolkit.keyPress(oKeyEvent)
oToolkit.keyRelease(oKeyEvent)
End Sub
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)
As shown in my previous post QODBC/QODBC3 is not that good to work with databases. I have found a year old suggestion here to use ADODB for SQL Server. Can anyone give an example showing or suggest a link explaining How to connect, query and get result using ADODB.Connection in Qt?
You need to use QAxObject.
First you should take a look at:
QAxObject documentation: doc.qt.io/qt-5/qaxobject.html
Active X data object documentation: msdn.microsoft.com/en-us/library/windows/desktop/ms676795(v=vs.85).aspx
Here is a sample code to get you started:
// Create connection
QAxObject *connection = new QAxObject("ADODB.Connection");
connection->dynamicCall("Open(\"Provider=SQLOLEDB.1;Integrated Security=SSPI;Initial Catalog=Inaz;Data Source=SERVER02\")");
// Execute query and get recordset
QAxObject *recordSet = connection->querySubObject("Execute(\"select column01 from table01\")");
// Get fields
// or check https://msdn.microsoft.com/en-us/library/ms681510(v=vs.85).aspx to see what you can do with and how to use a recordset
QAxObject *fields = recordSet->querySubObject("Fields");
Note: You will need to call CoInitialize to use ADODB. However QGuiApplication and QApplication call it internally so you might not always need to make the call yourself.
Having created a copy of an Access DB Backend in SQL Server, the Access Frontend has stopped showing the "Filter" list when the Filter button is pressed on the main form:
Before:
After:
I'm not sure what is causing this. In the old frontend I am opening the form like this:
Set rs = CurrentDb.OpenRecordset(sSQL)
Where sSQL is like:sSQL= "Select * from [EventReport]"
And in the new version I'm opening the form like this:
Set rs = CurrentDb.OpenRecordset(sSQL, dbOpenDynaset, dbFailOnError + dbSeeChanges)
I'm not sure if any of this is actually relevant to the issue, by any help is appreciated!
Tom
a bit more googling found the answer. In Access Options I needed to turn on the ODBC Fields in the Filter Lookup options for the Current Database
