Right now, I am just working with powershell, but I plan on porting this concept to JScript and using the .NET jsc with ActiveXObject('Access.Application'). I have opened my query using $accessapp.DoCmd.OpenQuery("MyQuery") and I can see that it is loaded using $accessapp.CurrentData.AllQueries("MyQuery"). I would like to use $accessapp.DoCmd.OutputTo(acOutputQuery, "MyQuery",<acFormat>, <file>), but for some reason, I keep getting the error:
Unexpected token 'acOutputQuery' in expression or statement
Just running $accessapp.DoCmd.OutputTo shows that is what is expected:
void OutputTo (AcOutputObjectType, Variant, Variant, Variant, Variant, Variant, Variant, AcExportQuality)
Every resource I have seen, including the Microsoft OutputTo documentation uses the acOutputObjectType in this manner, so I am completely stumped.
Okay, sorry it took me a while to get back. Thanks to #HansUp for leading me down the correct path. I Used the AcOutputObjectType enumeration link he posted as well as the MS Constants Enumeration. I'll give both a powershell example and an MS JScript one. I'll use acOutputQuery and xcFormatTXT as 1 and "MS-DOS" respectively here, but there are many others in the two links above.
powershell:
$acc = New-Object -com Access.Application
$acc.OpenCurrentDatabase("<path_to_file>.accdb")
$acc.DoCmd.OpenQuery("MyQuery")
$acc.DoCmd.OutputTo(1,"MyQuery","MS-DOS", "<path_to_output_file>.txt")
MS JScript:
function writeToTextFile(dbPath,queryName,outputPath){
var acc = new ActiveXObject("Access.Application"); //create new COM instance
acc.OpenCurrentDatabase(dbPath+".accdb"); //open the database
if(!acc.CurrentData.AllQueries(queryName).IsLoaded){
acc.DoCmd.OpenQuery(queryName); //load the query if it is not loaded yet
}
acc.DoCmd.OutputTo(1,queryName,"MS-DOS",outputPath+".txt"); //write to file
}
These two are kind of quick and dirty. Since I have this working in JScript now, I will probably make a writeToFile() function that takes the format as an argument. I considered using an object to map the name string to the enumeration, but I don't know how useful that would actually be. I suppose if you wanted, you could take the output object as an argument, too, but I only plan to use query objects for now.

I'm working on a web app in Rust. I'm using Tokio Postgres, Rocket and Tera (this may be relevant).
I'm using the following to connect to my DB which doesn't fail in either case.
(sql_cli, connection) = match tokio_postgres::connect("postgresql://postgres:*my_password*#localhost:8127/*AppName*", NoTls).await{
Ok((sql_cli, connection)) => (sql_cli, connection),
Err(e) => return Err(Redirect::to(uri!(error_display(MyError::new("Failed to make SQLClient").details)))),
};
My query is as follows. I keep my queries in a separate file (I'm self taught and find that easier).
let query= sql_cli.query(mycharactersquery::get_characters(user_id).as_str(), &[]).await.unwrap();
The get characters is as follows. It takes a user ID and should return the characters that they have made in the past.
pub fn get_characters(user_id: i16) -> String {
format!("SELECT * FROM player_characters WHERE user_id = {} ORDER BY char_id ASC;", user_id)
}
In my main file, I have one GET which is /mycharacters/<user_id> which works. This GET returns an HTML file. I have another GET which is /<user_id> which returns a Tera template. The first works fine and loads the characters, the second doesn't: it just loads indefinitely. I initially thought this was to do my lack of familiarity with Tera.
After some troubleshooting, I put some printouts in my code, the one before and after the SQL call work in /mycharacters/<user_id>, but only the one before writes to the terminal in /<user_id>. This makes me think that Tera isn't the issue as it isn't making it past the SQL call.
I've found exactly where it is going wrong, but I don't know why as it isn't giving an error.
Could someone please let me know if there is something obvious that I am missing or provide some assistance?
P.S. The database only has 3 columns, so an actual timeout isn't the cause.
I expected both of these SQL calls to function as I am connected to my database properly and the call is copied from the working call.
MATLAB's methodsview tool is handy when exploring the API provided by external classes (Java, COM, etc.). Below is an example of how this function works:
myApp = actxserver('Excel.Application');
methodsview(myApp)
I want to keep the information in this window for future reference, by exporting it to a table, a cell array of strings, a .csv or another similar format, preferably without using external tools.
Some things I tried:
This window allows selecting one line at a time and doing "Ctrl+c Ctrl+v" on it, which results in a tab-separated text that looks like this:
Variant GetCustomListContents (handle, int32)
Such a strategy can work when there are only several methods, but not viable for (the usually-encountered) long lists.
I could not find a way to access the table data via the figure handle (w/o using external tools like findjobj or uiinspect), as findall(0,'Type','Figure') "do not see" the methodsview window/figure at all.
My MATLAB version is R2015a.
Fortunately, methodsview.m file is accessible and allows to get some insight on how the function works. Inside is the following comment:
%// Internal use only: option is optional and if present and equal to
%// 'noUI' this function returns methods information without displaying
%// the table. `
After some trial and error, I saw that the following works:
[titles,data] = methodsview(myApp,'noui');
... and returns two arrays of type java.lang.String[][].
From there I found a couple of ways to present the data in a meaningful way:
Table:
dataTable = cell2table(cell(data));
dataTable.Properties.VariableNames = matlab.lang.makeValidName(cell(titles));
Cell array:
dataCell = [cell(titles).'; cell(data)];
Important note: In the table case, the "Return Type" column title gets renamed to ReturnType, since table titles have to be valid MATLAB identifiers, as mentioned in the docs.
I'm new to writing jasper reports (and SQL in general). We are trying to load an RTF or HTML file as a disclosure at the end of a report. The way we are doing this is by selecting the name of the file ("Disclosure") in part of the SQL:
SELECT
....
'Disclosure' as Disclosure
FROM
...
And then, obviously, there is a field for this:
<field name="Disclosure" class="java.lang.String"/>
At the end, in the summary section of the report, we use the loadfile utility:
<textFieldExpression class="java.lang.String"><![CDATA[JasperFileRuntimeUtility.loadFile($F{Disclosure}, $P{REPORT_PARAMETERS_MAP})]]></textFieldExpression>
If the report returns data, this works beautifully. But if the result of the original query does not return any records, then the disclosure is not included in the report (since the result of the query is nothing, obviously).
I thought we could easily work around this by providing the "Disclosure" as a Parameter, but when I change that to $P instead of $F. I get an error about invalid io file type.
I also tried creating a Variable and setting that $V to the value of the $P we are passing in, but no luck there either.
Is there a load file type of utility that will load a parameter like we are doing with the field? Any other suggestions?
Appreciate the help!!!
I have understood you question better now so I edit the answer, you are calling
JasperFileRuntimeUtility.loadFile($F{Disclosure}, $P{REPORT_PARAMETERS_MAP})
you have no clue what function is this but you know that if you pass the String "Disclosure" it works.
The class JasperFileRuntimeUtility is within your library (its not an official jasper report function), try to search your project or your libraries.
It has a static method public static String loadFile(String value, Map<?,?> map)
Calling the metod with where $F{Disclosure} = "Disclosure"
JasperFileRuntimeUtility.loadFile($F{Disclosure}, $P{REPORT_PARAMETERS_MAP})
or
JasperFileRuntimeUtility.loadFile("Disclosure", $P{REPORT_PARAMETERS_MAP})
will not make any different the result will be the same (since the method have no other idea then with what parameters you call it).
Normally also calling with a $P{Disclosure} = "Disclosure"
JasperFileRuntimeUtility.loadFile($P{Disclosure}, $P{REPORT_PARAMETERS_MAP})
would be the same, but since the the parameter map is passed the function can see this parameter and maybe do something else...
More likely however since the parameter map is passed to function, you may have scriptlet or other calls that set static fields, and when you have no result the call to loadFile is not working since these static fields have not been set.
So if it is not working passing "Disclosure" this is most certainly the case..
Have fun!
I'm currently working on benchmarking a RESTful service I've made, and part of that is making sure it runs in a reasonable amount of times for a large array of parameters. For example, let's say I have RESTful API of the form some_site.com/item?item_id=y. In that case to be sure my service is working as fast as I'd like it to work, I'd want to try out many values for y one by one, preferably coming from some text file. I can't figure out any way of doing this in ab or httperf. I'm open to using a different benchmarking program if I have, but would prefer something simple and light. What I want to do seems like something pretty standard, so I'm guessing there must already be a program that let's me do it, but an hour or so of googling hasn't gotten me an answer. Ideas?
Answer: Jmeter (which is apparently awesome). This faq explains how to do it. Hopefully this helps someone else, as it took me like a day of searching to figure this out.
I have just had some good experience with using JavaScript (via BSF/Rhino) in JMeter.
I have put one thread group in my test plan and stick a 'Simple Controller' with two elements under it - 'HTTP Request' sampler and 'BSF PreProcessor'.
Set BSF language to 'javascript' and either type the code into the text box or point it to a file (use full path or relative to CWD of JMeter process).
/* Since `Math.random()` gives us float, we use `java.util.Random()`
* see: http://docs.oracle.com/javase/7/docs/api/java/util/Random.html */
var Random = new Packages.java.util.Random();
var min = 10-1;
var max = 2;
var maxLines = (min)+Random.nextInt(max-min);
var s = '';
for (var d = 0; d <= maxLines; d++) {
s += d.toString()+','+Random.nextInt(1000).toString()+'\n';
}
// s => '0,312\n1,104\n2,608\n'
vars.put('PAYLOAD', s);
Now I can refer to ${PAYLOAD} in the HTTP request!
You can generate JSON, but you will need to upgrade jakarta-jmeter-2.5.1/lib/js-1.6R5.jar with the newest version of Rhino to get JSON.stringify and JSON.parse. That worked perfectly for me also, though I thought I'd put a simple example here.
You can use BSF pre-processor for URL params as well, just set another variable with vars.put('X', 'some value') and pass it as ${X} in the request parameter.
This blog post helped quite a bit, by the way.
I am using code similar to this Support / KB article to return multiple recordsets to my C# program.
But I don't want C# code to be dependant on the physical sequence of the recordsets returned, in order to do it's job.
So my question is, "Is there a way to determine which set of records from a multiplerecordset resultset am I currently processing?"
I know I could probably decipher this indirectly by looking for a unique column name or something per resultset, but I think/hope there is a better way.
P.S. I am using Visual Studio 2008 Pro & SQL Server 2008 Express Edition.
No, because the SqlDataReader is forward only. As far as I know, the best you can do is open the reader with KeyInfo and inspect the schema data table created with the reader's GetSchemaTable method (or just inspect the fields, which is easier, but less reliable).
I spent a couple of days on this. I ended up just living with the physical order dependency. I heavily commented both the code method and the stored procedure with !!!IMPORTANT!!!, and included an #If...#End If to output the result sets when needed to validate the stored procedure output.
The following code snippet may help you.
Helpful Code
Dim fContainsNextResult As Boolean
Dim oReader As DbDataReader = Nothing
oReader = Me.SelectCommand.ExecuteReader(CommandBehavior.CloseConnection Or CommandBehavior.KeyInfo)
#If DEBUG_ignore Then
'load method of data table internally advances to the next result set
'therefore, must check to see if reader is closed instead of calling next result
Do
Dim oTable As New DataTable("Table")
oTable.Load(oReader)
oTable.WriteXml("C:\" + Environment.TickCount.ToString + ".xml")
oTable.Dispose()
Loop While oReader.IsClosed = False
'must re-open the connection
Me.SelectCommand.Connection.Open()
'reload data reader
oReader = Me.SelectCommand.ExecuteReader(CommandBehavior.CloseConnection Or CommandBehavior.KeyInfo)
#End If
Do
Dim oSchemaTable As DataTable = oReader.GetSchemaTable
'!!!IMPORTANT!!! PopulateTable expects the result sets in a specific order
' Therefore, if you suddenly start getting exceptions that only a novice would make
' the stored procedure has been changed!
PopulateTable(oReader, oDatabaseTable, _includeHiddenFields)
fContainsNextResult = oReader.NextResult
Loop While fContainsNextResult
Because you're explicitly stating in which order to execute the SQL statements the results will appear in that same order. In any case if you want to programmatically determine which recordset you're processing you still have to identify some columns in the result.
