  • Why is sql server giving a conversion error when submitting date.today to a datetime column?

    - by kpierce8
    I am getting a conversion error every time I try to submit a date value to sql server. The column in sql server is a datetime and in vb I'm using Date.today to pass to my parameterized query. I keep getting a sql exception Conversion failed when converting datetime from character string. Here's the code Public Sub ResetOrder(ByVal connectionString As String) Dim strSQL As String Dim cn As New SqlConnection(connectionString) cn.Open() strSQL = "DELETE Tasks WHERE ProjID = @ProjectID" Dim cmd As New SqlCommand(strSQL, cn) cmd.Parameters.AddWithValue("ProjectID", 5) cmd.ExecuteNonQuery() strSQL = "INSERT INTO Tasks (ProjID, DueDate, TaskName) VALUES " & _ " (@ProjID, @TaskName, @DueDate)" Dim cmd2 As New SqlCommand(strSQL, cn) cmd2.CommandText = strSQL cmd2.Parameters.AddWithValue("ProjID", 5) cmd2.Parameters.AddWithValue("DueDate", Date.Today) cmd2.Parameters.AddWithValue("TaskName", "bob") cmd2.ExecuteNonQuery() cn.Close() DataGridView1.DataSource = ds.Projects DataGridView2.DataSource = ds.Tasks End Sub Any thoughts would be greatly appreciated.

  • Update MySQL table from jsp

    - by vishnu
    I have these in a jsp file. But these values are not updated in the mysql table. May be it is not commiting. How can i solve this ?

  • SQLAlchemy automatically converts str to unicode on commit

    - by Victor Stanciu
    Hello, When inserting an object into a database with SQLAlchemy, all it's properties that correspond to String() columns are automatically transformed from <type 'str'> to <type 'unicode'>. Is there a way to prevent this behavior? Here is the code: from sqlalchemy import create_engine, Table, Column, Integer, String, MetaData from sqlalchemy.orm import mapper, sessionmaker engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() table = Table('projects', metadata, Column('id', Integer, primary_key=True), Column('name', String(50)) ) class Project(object): def __init__(self, name): self.name = name mapper(Project, table) metadata.create_all(engine) session = sessionmaker(bind=engine)() project = Project("Lorem ipsum") print(type(project.name)) session.add(project) session.commit() print(type(project.name)) And here is the output: <type 'str'> <type 'unicode'> I know I should probably just work with unicode, but this would involve digging through some third-party code and I don't have the Python skills for that yet :)

  • Python regular expression help

    - by dlw
    Hi SO, I can't seem to create the correct regular expression to extract the correct tokens from my string. Padding the beginning of the string with a space generates the correct output, but seems less than optimal: >>> import re >>> s = '-edge_0triggered a-b | -level_Sensitive c-d | a-b-c' >>> re.findall(r'\W(-[\w_]+)',' '+s) ['-edge_0triggered', '-level_Sensitive'] # correct output Here are some of the regular expressions I've tried, does anyone have a regex suggestion that doesn't involve changing the original string and generates the correct output >>> re.findall(r'(-[\w_]+)',s) ['-edge_0triggered', '-b', '-level_Sensitive', '-d', '-b', '-c'] >>> re.findall(r'\W(-[\w_]+)',s) ['-level_Sensitive'] Thanks -- DW

  • concatenating strings from two different rows in a table

    - by Azeem
    Hello, We are attempting to rework the SQL in a product. The product stores XML in a table as follows: XML_STORAGE - UID IDENTITY - PARENT_ID INTEGER - SEQ INTEGER - XML VARCHAR(3800) The current way of doing this is as follows: Retrieve all ROWS for PARENT_ID = n. Then go over the fetched rows in the code and concatenate the XML strings into one large XML before parsing. The SEQ column is used to ORDER the result so the XML strings can be concatenated properly. Hopefully that is clear. What we are attempting to do is rework this so we can use a SQL variant to retrieve the whole string and just fetch one row back from DB2. Is there a DB2 function that will allow us to concatenate the string in all of these rows into one large string in the resultset. How would such a SQL look. Please let me know. Any help is much appreciated. Thanks! - Azeem

  • Spring struts and forms

    - by Kiva
    Hi guy, I need to integrate struts with spring for a project. I read the doc to ingrate struts and it's ok for classic beans but I have a problem for my forms. I have a form like this in my struts-config.xml: <form-beans> <form-bean name="creationForm" type="org.apache.struts.validator.DynaValidatorActionForm" > <form-property name="libelle" type="java.lang.String" /> <form-property name="quantite" type="java.lang.String" /> <form-property name="prix" type="java.lang.String" initial="10" /> </form-bean> But it's strange for me to have a "type" in struts-config because it's spring which manages beans. I don't found anything in the doc to manage forms by spring and the attribute "type" is mandatory for form in struts-config. Someone can help me please ?

  • Avoiding nesting two for loops

    - by chavanak
    Hi, Please have a look at the code below: import string from collections import defaultdict first_complex=open( "residue_a_chain_a_b_backup.txt", "r" ) first_complex_lines=first_complex.readlines() first_complex_lines=map( string.strip, first_complex_lines ) first_complex.close() second_complex=open( "residue_a_chain_a_c_backup.txt", "r" ) second_complex_lines=second_complex.readlines() second_complex_lines=map( string.strip, second_complex_lines ) second_complex.close() list_1=[] list_2=[] for x in first_complex_lines: if x[0]!="d": list_1.append( x ) for y in second_complex_lines: if y[0]!="d": list_2.append( y ) j=0 list_3=[] list_4=[] for a in list_1: pass for b in list_2: pass if a==b: list_3.append( a ) kvmap=defaultdict( int ) for k in list_3: kvmap[k]+=1 print kvmap Normally I use izip or izip_longest to club two for loops, but this time the length of the files are different. I don't want a None entry. If I use the above method, the run time becomes incremental and useless. How am I supposed to get the two for loops going? Cheers, Chavanak

  • Java variables -> replace? RAM optimization

    - by poeschlorn
    Hi guys, I just wanted to know what happens behind my program when I declare and initialize a variable and later initialize it again with other values, e.g. an ArrayList or something similar. What happens in my RAM, when I say e.g. this: ArrayList<String> al = new ArrayList<String>(); ...add values, work with it and so on.... al = new ArrayList<String>(); So is my first ArrayList held in RAM or will the second ArrayList be stored on the same position where the first one has been before? Or will it just change the reference of "al"? If it is not replaced...is there a way to manually free the RAM which was occupied by the first arraylist? (without waiting for the garbage collector) Would it help to set it first =null? Nice greetings, poeschlorn

  • How to replace "(" with "\(" in the regexp, Emacs/elisp flavor?

    - by polyglot
    Question as title. More specifically, I'm rather tired of having to type \(, etc. every time I want a parenthesis in Emacs's (interactive) regexp functions (not to mention the \\( in code). So I wrote something like (defadvice query-replace-regexp (before my-query-replace-regexp activate) (ad-set-arg 0 (replace-regexp-in-string "(" "\\\\(" (ad-get-arg 0))) (ad-set-arg 0 (replace-regexp-in-string ")" "\\\\)" (ad-get-arg 0))))) in hope that I can conveniently forget about emacs's idiosyncrasy in regexp during "interaction mode". Except I cannot get the regexp right... (replace-regexp-in-string "(" "\\\\(" "(abc") gives \\(abc instead of the wanted \(abc. Other variations on the number of slashes just gives errors. Thoughts? Since I started questioning, might as well ask another one: since lisp code is not supposed to use interactive functions, advicing query-replace-regexp should be okay, am I correct?

  • iPhone SDK Nested For Loop performance

    Hi All, I have a NSArray of string id and a NSDictionary of NSDictionary objects. I am currently looping through the string id array to match the id value in the NSDictionary. There are around 200 NSDictionary objects and only 5 or so string ID. My current code is such: for (NSString *Str in aArr) { for (NSDictionary *a in apArr) { if ([a objectForKey:@"id"] == Str) { NSLog(@"Found!"); } } } The performance of the above code is really slow and I was wondering if there is a better way to do this?

  • Handling duplicate nodes in XML

    - by JYelton
    Scenario: I am parsing values from an XML file using C# and have the following method: private static string GetXMLNodeValue(XmlNode basenode, string strNodePath) { if (basenode.SelectSingleNode(strNodePath) != null) return (basenode.SelectSingleNode(strNodePath).InnerText); else return String.Empty; } To get a particular value from the XML file, I generally pass the root node and a path like "parentnode/item" I recently ran into an issue where two nodes at the same document level share the same name. Question: What is the best way to get the values for duplicate-named nodes distinctly? My thought was to load all values matching the node name into an array and then using the array index to refer to them. I'm not sure how to implement that, though. (I'm not well-versed in XML navigation.)

  • groovy closure parameters

    - by Don
    Hi, The following example of using the sendMail method provided by the grails mail plugin appears in this book. sendMail { to "[email protected]" subject "Registration Complete" body view:"/foo/bar", model:[user:new User()] } I understand that the code within {} is a closure that is passed to sendMail as a parameter. I also understand that to, subject and body are method calls. I'm trying to figure out what the code that implements the sendMail method would look like, and my best guess is something like this: MailService { String subject String recipient String view def model sendMail(closure) { closure.call() // Code to send the mail now that all the // various properties have been set } to(recipient) { this.recipient = recipient } subject(subject) { this.subject = subject; } body(view, model) { this.view = view this.model = model } } Is this reasonable, or am I missing something? In particular, are the methods invokedwithin the closure (to, subject, body), necessarily members of the same class as sendMail? Thanks, Don

  • Why does this explicit call of a Scala method allow it to be implicitly resolved?

    - by Matt R
    Why does this code fail to compile, but compiles successfully when I uncomment the indicated line? (I'm using Scala 2.8 nightly). It seems that explicitly calling string2Wrapper allows it to be used implicitly from that point on. class A { import Implicits.string2Wrapper def foo() { //string2Wrapper("A") ==> "B" // <-- uncomment } def bar() { "A" ==> "B" "B" ==> "C" "C" ==> "D" } object Implicits { implicit def string2Wrapper(s: String) = new Wrapper(s) class Wrapper(s: String) { def ==>(s2: String) {} } } }

  • How can I match at the beginning of any line, including the first, with a Perl regex?

    - by JoelFan
    According the the Perl documentation on regexes: By default, the "^" character is guaranteed to match only the beginning of the string ... Embedded newlines will not be matched by "^" ... You may, however, wish to treat a string as a multi-line buffer, such that the "^" will match after any newline within the string ... you can do this by using the /m modifier on the pattern match operator. The "after any newline" part means that it will only match at the beginning of the 2nd and subsequent lines. What if I want to match at the beginning of any line (1st, 2nd, etc.)? EDIT: OK, it seems that the file has BOM information (3 chars) at the beginning and that's what's messing me up. Any way to get ^ to match anyway? EDIT: So in the end it works (as long as there's no BOM), but now it seems that the Perl documentation is wrong, since it says "after any newline"
