  • How to crosscheck two tables and insert relevant data into a new table in MYSQL?

    - by JackDamery
    I'm trying to crosscheck a row that exists in two tables using a MYSQL query in phpmyadmin and then if a userID is found in both tables, insert their userID and user name into another table. Here's my code: INSERT INTO userswithoutmeetings SELECT user.userID IF('user.userID'='meeting.userID'); I keep getting plagued by this error: 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IF('user.userID'='meeting.userID')' at line 3 Other statements I've tried have worked but not deposited the values in the table.

  • C# creating a custom user interface

    - by CSharpInquisitor
    Hi, I have a SQL database holding a number of numeric and text values that get updated regularly. The exact number/type/names of these data points can change depending on the source of the database writes. I would like to create a user interface editor, where the user can add database points to the UI and arrange them and format them as they want. If a new point is added to the database they can right click on the UI and say "add this point" and choose from a list of database points. I'm looking for some pointers on where to start on creating this editor application, could something clever be done using XAML to dynamically create std WPF controls at runtime? Thanks in advance for any help, Si

  • MySQL Database || Tables Issue

    - by user1780103
    I'm trying to write up a script where the user is able to purchase an amount of points for dollars. I want the transaction to be inserted into MySQL. I keep facing a: "Column count doesn't match value count at row 1" error. And I have no idea what I'm doing wrong. I have written up this: mysql_query("INSERT INTO paypal_donations VALUES (NULL, ".$account_id.", ".$char_id.", ".$price.", ".$dp.", NOW(), NOW(), 'Started', 0, 0, '', '');") or die(mysql_error()); But I don't know what to execute in MySQL, since I've never worked with it before. Could anyone write up a quick script that I can insert into MySQL for it to work.

  • Implicit type conversion in DB/2 inserts?

    - by IronGoofy
    We're using SQL Inserts to insert some data via a script into DB/2 tables, e.g. CREATE TABLE TICKETS (TICKETID VARCHAR(10) NOT NULL); On my home installation, this statement works fine (note that I'm using an integer which is autoatically cast into a VarChar): INSERT INTO TICKETS (TICKETID) VALUES (1); while at my customer's site I get a type error. My question(s): Is this behavior version dependent? (I use a DB2 Express V9.7, while the customer has an Enterprise V9.5) Is there a config option to change the behavior? (I would like my home install to behave as close as possible as the production environment is going to be.)

  • Serialize object from within

    - by Maximus
    I have the class testClass which has the method save. This method saves object to a database. But it needs to serialize object before saving. How can I serialize object from within the class to do that? class testClass { private $prop = 777; public function save() { $serializedObject = serialize(self); DB::insert('objects', array('id', 'object')) ->values(array(1, $serializedObject)) ->execute(); } } serialize(self) obviously doesn't work.

  • Junit | How to test parameters in a method

    - by MMRUser
    How do I test parameters inside a method itself. For example class TestClass { public void paraMethod(String para1, String para2) { String testPara1 = para1; String testPara2 = para2; } } class TestingClass { @Test public void testParaMethod () throws Exception { String myPara1 = "MyPara1"; String myPara2 = "MyPara2"; new TestClass().paraMethod(myPara1, myPara2); } } Ok, so is it possible to test if the testPara1 and testPara2 are properly set to the values that I have passed? Thanks.

  • Query returning an ascending group number

    - by Dougman
    I have a query like below that has groups (COL1) and that group's values (COL2). select col1, col2 from (select 'A' col1, 1 col2 from dual union all select 'A' col1, 2 col2 from dual union all select 'B' col1, 1 col2 from dual union all select 'B' col1, 2 col2 from dual union all select 'C' col1, 1 col2 from dual union all select 'C' col1, 2 col2 from dual ) order by col1, col2; The output of this query looks like: COL1 COL2 ---- ---- A 1 A 2 B 1 B 2 C 1 C 2 What I need is a query that will return an ordered number increasing for each different group (COL1). It seems like there would be a simple way to accomplish this (maybe with analytics) but for some reason it is escaping me. GRPNUM COL1 COL2 ------ ---- ---- 1 A 1 1 A 2 2 B 1 2 B 2 3 C 1 3 C 2 I am running Oracle 10gR2.

    - by user187580
    Hello I have some data in the format of C222 = 50 C1234P687 = 'some text' C123YYY = 'text' C444 = 89 C345 = 3 C122P687 = 'some text' C122YYY = 'text' .... .... so basically 3 different forms "C" number = value, example - C444 = 89 "C" number "P" number = value, example - C123P687 = 'some text' "C" number "YYY" = value Only number is of variable length on the left side of (=) sign. Values vary. I want to store the data in db as INSERT INTO datatable c_id = "number after C" p_id = "number after P" // if it exists for a line of data value = 'value' yyy = 'value' Any ideas how to retrieve these numbers?

  • How do you keep the value of global variables (namely a struct variable) between postbacks?

    - by user3702304
    I'm new to this and have already searched for this with not much luck :( Lets say I have defined a struct array globally and filled the array with data on an Ajax ModalPopupExtender. I then have a ddl_SelectedIndexChanged event that does a postback and seems to recycle my array. Is there a way to fire the ddl_SelectedIndexChanged event to perform some code without doing a postback? Or is there an easy way to make the array of type struct retain it's values? (I am creating a website btw) Thanks in advance...

  • Easiest way to merge two List<T>s

    - by Chris McCall

What's the easiest way to go about this in C# using .Net 3.5?

  • Help with implementing a function to change size of dynamic array

    - by iRobot
    I'm trying to write a function that will change the size of a dynamic array to a new size. In my header file, I have: Image **images; //pointer to a dynamic array of image pointers int maximum; //size I want to do this by allocating a new array and copying the values over without changing their indices. If there are non-null pointers outside the range newmax, then we cant do this. So heres what I have: There are no compilation or runtime errors. However, I find that the new array isnt getting sized right. When I run the following test case: I should get an index out of bounds error, but instead the system lets it slide. Can anyone see the mistake? I've looked for hours but cant find anything.

  • How do stop form posting to mysql if database contains a specific ID?

    - by user342391
    I have a form that I am using to post data to mysql. Before submitting the form I want to check the database and see if there are any fields in the column 'customerid' that equal 'userid' and if so not to post the form. Basically, I am trying to limit my users from posting more than once. Users will be able to login to my system and make ONE post. They will be able to delete and modify their post but are only limited to one post. How would I do this??? Code so far: <?php include '../login/dbc.php'; page_protect(); $userid = $_SESSION['user_id']; $sql="INSERT INTO content (customerid, weburl, title, description) VALUES ('$_POST[userid]','$_POST[webaddress]','$_POST[pagetitle]','$_POST[pagedescription]')"; if (!mysql_query($sql)) { die('Error: ' . mysql_error()); } echo "1 record added"; ?>

  • C# equivalent of recv?

    - by mlh
    Hello, I have a portion of C code that I am trying to port over to C#. In my C code, I create a socket and then issue a receive command. The receive command is void receive(mysocket, char * command_buffer) { recv(mysocket, command_buffer, COMMAND_BUFFER_SIZE, 0); } now, the command buffer is returned with new values including command_buffer[8] being a pointer to a string. I'm really confused as to how to do this in C# because C# Read() command specifically takes in bytes and not char. The important part is that I get the pointer to the string. Any ideas?

  • AJAX Panel not throwing exceptions

    - by Grant
    Hi, i have just noticed something strange in some asp.net markup. I have a standard form with a couple of textboxes and a submit button. When clicked the code behind will attempt to perform some logic and then return. If the input values are not valid it used to throw an exception. The moment i wrapped the controls in an AJAX update panel and try to submit bad data, no exception is thrown and the panel returns like nothing was wrong. Does anyone know how to return this to the previous behavior whilst keeping the update panel?

  • Group Objects by Common Key

    - by Marshmellow1328
    I have a list of Customers. Each customer has an address and some customers may actually have the same address. My ultimate goal is to group customers based on their address. I figure I could either put the customers in some sort of list-based structure and sort on the addresses, or I could drop the objects into some sort of map that allows multiple values per key. I will now make a pretty picture: List: A1 - C1, A1 - C2, A2 - C3, A3 - C4, A3 - C5 Map: A1 A2 A3 C1 C3 C4 C2 C5 Which option (or any others) do you see as the best solution? Are there any existing classes that will make development easier?

  • Using different validation rules based on user input.

    - by chiefanov
    I have a simple form: a combobox and a textbox. My combobox has 2 values: A and B. When value A is selected I want textbox to use a validation rule. When value B is selected there should be no validation rules applied to the textbox. I've read an article that has a solution and I'm trying to use it, but had no luck so far, and I think there might be a more elegant solution. Has anyone done anything like this before? Any ideas are highly appreciated.

  • Strange Locking Behaviour in SQL Server 2005

    - by SQL Learner
    Can anyone please tell me why does the following statement inside a given stored procedure returns repeated results even with locks on the rows used by the first SELECT statement? BEGIN TRANSACTION DECLARE @Temp TABLE ( ID INT ) INSERT INTO @Temp SELECT ID FROM SomeTable WITH (ROWLOCK, UPDLOCK, READPAST) WHERE SomeValue <= 10 INSERT INTO @Temp SELECT ID FROM SomeTable WITH (ROWLOCK, UPDLOCK, READPAST) WHERE SomeValue >= 5 SELECT * FROM @Temp COMMIT TRANSACTION Any values in SomeTable for which SomeValue is between 5 and 10 will be returned twice, even though they were locked in the first SELECT. I thought that locks were in place for the whole transaction, and so I wasn't expecting the query to return repeated results. Why is this happening?

  • putting data from a for loop into a table using matlab and fprintf

    I am trying to put the following data from my for loop into a table formatted so that there are 11 values of F in each column, with a total of 4 columns. but I am always ending up with one long column of my data instead of the four columns I want. I was wondering if there is some way to put the data into a matrix and then reshape it, but I am having trouble. Any help greatly appreciated. fprintf ('Electrostatic Forces:\n') for r = 1:4; q2 = 0: 1*10^-19: 1*10^-18; for F = coulomb(q2,r); fprintf ('%d\n',F) end end Where the code for the function coulomb is function F = coulomb (q2,r); k = 8.98*10^9; q1 = 1.6*10^-19; F = k*abs(q1*q2)/r^2; end
