  • Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID

    - by Jian Lin
    Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID); ? The ( ) usually is for specifying grouping of something. But in this case, are we supposed to be able to use 2 or more field names... in the example above, it can be all clear that it is 1 field, is it just that the parser is not made to bypass the ( ) when it is all clear? (such as in the language Ruby).

  • How do i make formatted json in C#.NET

    - by acidzombie24
    I am using .NET json parser and i would like to serialize my config file so it is readable instead of {"blah":"v", "blah2":"v2"} to something nicer like { "blah":"v", "blah2":"v2" } my code is something like using System.Web.Script.Serialization; var ser = new JavaScriptSerializer(); configSz = ser.Serialize(config); using (var f = (TextWriter)File.CreateText(configFn)) { f.WriteLine(configSz); f.Close(); }

  • Difference in DocumentBuilder.parse when using JRE 1.5 and JDK 1.6

    - by dhiller
    Recently at last we have switched our projects to Java 1.6. When executing the tests I found out that using 1.6 a SAXParseException is not thrown which has been thrown using 1.5. Below is my test code to demonstrate the problem. import java.io.StringReader; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.transform.stream.StreamSource; import javax.xml.validation.SchemaFactory; import org.junit.Test; import org.xml.sax.InputSource; import org.xml.sax.SAXParseException; /** * Test class to demonstrate the difference between JDK 1.5 to JDK 1.6. * * Seen on Linux: * * <pre> * #java version "1.6.0_18" * Java(TM) SE Runtime Environment (build 1.6.0_18-b07) * Java HotSpot(TM) Server VM (build 16.0-b13, mixed mode) * </pre> * * Seen on OSX: * * <pre> * java version "1.6.0_17" * Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025) * Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode) * </pre> * * @author dhiller (creator) * @author $Author$ (last editor) * @version $Revision$ * @since 12.03.2010 11:32:31 */ public class TestXMLValidation { /** * Tests the schema validation of an XML against a simple schema. * * @throws Exception * Falls ein Fehler auftritt * @throws junit.framework.AssertionFailedError * Falls eine Unit-Test-Pruefung fehlschlaegt */ @Test(expected = SAXParseException.class) public void testValidate() throws Exception { final StreamSource schema = new StreamSource( new StringReader( "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" + "<xs:schema xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" " + "elementFormDefault=\"qualified\" xmlns:xsd=\"undefined\">" + "<xs:element name=\"Test\"/>" + "</xs:schema>" ) ); final String xml = "<Test42/>"; final DocumentBuilderFactory newFactory = DocumentBuilderFactory.newInstance(); newFactory.setSchema( SchemaFactory.newInstance( "http://www.w3.org/2001/XMLSchema" ).newSchema( schema ) ); final DocumentBuilder documentBuilder = newFactory.newDocumentBuilder(); documentBuilder.parse( new InputSource( new StringReader( xml ) ) ); } } When using a JVM 1.5 the test passes, on 1.6 it fails with "Expected exception SAXParseException". The Javadoc of the DocumentBuilderFactory.setSchema(Schema) Method says: When errors are found by the validator, the parser is responsible to report them to the user-specified ErrorHandler (or if the error handler is not set, ignore them or throw them), just like any other errors found by the parser itself. In other words, if the user-specified ErrorHandler is set, it must receive those errors, and if not, they must be treated according to the implementation specific default error handling rules. The Javadoc of the DocumentBuilder.parse(InputSource) method says: BTW: I tried setting an error handler via setErrorHandler, but there still is no exception. Now my question: What has changed to 1.6 that prevents the schema validation to throw a SAXParseException? Is it related to the schema or to the xml that I tried to parse?

  • Send shrink Command to Microsoft SQL Database file via Ado.net connection

    - by user287107
    How is it possible to execute a direct SQL command to an ADO.NET connected database? I want to send a DBCC SHRINKDATABASE to the SQL server, to compress the current datafile after a big deletion process. The function ObjectContext::CreateQuery returns a parser error after the DBCC command. Is there any other way to shrink the database file, or another way to send the SQL command directly to the SQL Server?

  • UML diagram for application architecture?

    - by fayer
    i'm trying to map my whole application in a UML diagram and i wonder what diagram type i should use. im not doing this in class level, rather from a bird eye's perspective. single application object (patterns: singleton)(examples: CodeIgniter application) that composes multiple module objects (patterns: singleton, facades)(examples: guestbook, addressbook) that compose multiple low level stand alone objects (examples: mysql mapper, doctrine mapper) that compose various 3rd and in-house libraries (examples: doctrine, solr, xml-parser) what UML diagram is suited for this kind of overview presentation? thanks

  • Can these sorts of programs exist in every Turing-complete language?

    - by I can't tell you my name.
    In every Turing-Complete language, is it possible to create a working Compiler for itself which first runs on an interpreter written in some other language and then compiles it's own source code? (Bootstrapping) Standards-Compilant C++ compiler which outputs binaries for, e.g.: Windows? Regex Parser and Evaluater? World of Warcraft clone? (Assuming the language gets the necessary API bindings as, for example, OpenGL and the WoW source code is available) (Everything here theoretical) Let's take Brainf*ck as an example language.

  • Convert html/css print media display to .doc with appropriate page breaks?

    - by DevelopingChris
    I'm looking to export a page that looks good in print media, to word. Can this be done automatically, or mostly automatically with office apis? The alternative is to create a program that reads all our style meta data and font meta data and convert to word and force a download. The issue is our style metadata is already built for css, its a web app after all. And writing my own css parser, doesn't sound like a good use of time.

  • Library for parsing arguments GNU-style?

    - by Delan Azabani
    I've noticed the basic 'style' of most GNU core applications whereby arguments are: --longoption --longoption=value or --longoption value -abcdefg (multiple options) -iuwww-data (option i, u = www-data) They follow the above style. I want to avoid writing an argument parser if there's a library that does this using the above style. Is there one you know of?

  • How to parse an XML string in TDI

    - by ongle
    I am new to TDI. I have a TDI assembly line that calls a web service (ibmdi.InvokeSoapWS) which returns the result as a string in the work attribute 'xmlString'. I then have an AttributeMap that attempts to parse the xml and extract a value (the node it seeks is a few nodes deep). var parser = system.getParser('ibmdi.SOAP'); var xmlString = work.getString('xmlString'); var entity = parser.parseRequest(xmlString); task.dump(entity); The trouble is, the parsed object does not contain an accurate representation of the XML. It contains only two attributes, the first is correctly the first node following the soap body (e.g., ns0:SomeNodeReply), the second being a node inside the first (e.g., ns0:DetailCount). And as far as I can determine, both attributes are just strings so I cannot recurse into the object graph. Below is a sample soap reply: <?xml version="1.0" encoding="utf-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Body> <ns0:SomeNodeReply xmlns:ns0="http://xmlns.example.com/unique/default/namespace/1136581686664"> <ns0:Status> <ns0:StatusCD>000</ns0:StatusCD> <ns0:StatusDesc /> </ns0:Status> <ns0:DetailCount>1</ns0:DetailCount> <ns0:SomeDetail> <ns0:CodeA>Foo</ns0:CodeA> <ns0:CodeB>Bar</ns0:CodeB> </ns0:SomeDetail> </ns0:SomeNodeReply> </SOAP-ENV:Body> </SOAP-ENV:Envelope> And below is a sample dump of the parsed string: 19:03:23 CTGDIS003I *** Start dumping Entry 19:03:23 Operation: generic 19:03:23 Entry attributes: 19:03:23 SOAP_CALL (replace): 'ns0:SomeNodeReply' 19:03:23 ns0:DetailCount(replace): '1' 19:03:23 CTGDIS004I *** Finished dumping Entry All I really need to do is be able to parse out a value that may or may not be there, depending on the value of another node (e.g., DetailCount == 1, get CodeA otherwise return empty string). I am open to changing anything about how this works if I can extract the data into the work Entry.

  • dijit/form/Select broken in Internet Explorer using Esri Javascript 3.7

    - by disuse
    After developing a web map app in Firefox, I tested my code in Internet Explorer (company standard) to discover that the dijit/form/Select is misbehaving using the latest Esri JavaScript v3.7. The issue I am seeing is that the Select will not update/change from the first option in the list when using v3.7. If I bump the version down to 3.6, it works as expected. I've tried IE browser modes from 7 to 10 and am experiencing the same behavior between all of them. Can someone confirm they are experiencing the same thing? Example in 3.7 - http://jsbin.com/aVIsApO/1/edit Example in 3.6 - http://jsbin.com/odIxETu/7/edit Codeblock var url = "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/Street_Trees/FeatureServer/0"; var frmTrees; require([ "esri/tasks/query", "esri/tasks/QueryTask", "dojo/dom-construct", "dijit/form/Select", "dojo/parser", "dijit/registry", "dojo/on", "dojo/ready", "dojo/_base/connect", "dojo/domReady!" ], function( Query, QueryTask, domConstruct, Select, parser, registry, on, ready, connect ) { ready(function() { frmTrees = registry.byId("trees"); var qt = new QueryTask(url); var query = new Query(); query.where = "FID < 25"; query.orderByFields = ["qSpecies"]; query.returnGeometry = false; query.outFields = ["qSpecies", "TreeID"]; query.groupByFieldsForStatistics = ["qSpecies"]; //query.returnDistinctValues = true; qt.execute(query, function(results) { //var frm_domain_area = dom.byId("domain_area"); var testVals = {}; for (var i = 0; i < results.features.length; i++) { var id = results.features[i].attributes.TreeID; var desc = results.features[i].attributes.qSpecies; if (!testVals[id]) { testVals[id] = true; var selectElem = domConstruct.create("option",{ label: desc + " (" + id + ")", value: id }); frmTrees.addOption(selectElem); } } }); frmTrees.on("change", function() { console.debug(frmTrees.get("value")); }); }); });

  • How can I make xmlpp::DomParser less verbose on errors?

    - by Beau Simensen
    How can I make xmlpp::DomParser be less verbose on errors? Right now, if parsing fails, I get a bunch of text printed to my console and I'd just as soon have that not be visible. Entity: line 1: parser error : Opening and ending tag mismatch: feed line 1 and fed <feed><entry id='5' /></fed> I don't see a lot of options for xmlpp::DomParser but I have to believe this is something that can be disabled/tweaked.

  • Are there any Parsing Expression Grammar (PEG) libraries for Javascript or PHP?

    - by Peter J. Wasilko
    I find myself drawn to the Parsing Expression Grammar formalism for describing domain specific languages, but so far the implementation code I've found has been written in languages like Java and Haskell that aren't web server friendly in the shared hosting environment that my organization has to live with. Does anyone know of any PEG libraries or PackRat Parser Generators for Javascript or PHP? Of course code generators in any languages that can produce Javascript or PHP source code would do the trick.
