    This query fails when I add the line shown... :BEGIN FAIL: I have this so far Select Companyid, count(*) as cnt from mytable where State is not null and cnt = 1 <------------------------- FAIL group by CompanyID :END FAIL: Any way to do this?

  • symfony 1.4 embedForm not returning all embedded forms

    - by Patrick
    I have a form with multiple embedded forms and symfony is not binding all the embedded forms. The layout is a m-to-m layout: activity: id: link: id: activity_id: FOREIGN KEY to activity table other_data_id: FOREIGN KEY to other_data table other_data: id: For instance I have 7 identical embedded forms iterated at the end of each name (ie- form_1, form_2, ..., form_7). With the new and edit forms all the 7 fields display properly, but when I submit the form, the embedded forms after a certain number just aren't in the embedded forms array of the sfForm. I have two different embedded forms, the first form stops binding at 5 and the second form stops binding at 4. I've looked at the array of posted values through $request->getPostParameters(); and all the fields are there. If I manually enter the data into the database, the binding works without a problem. Any ideas would be greatly appreciated!

    - by codo
    I have created a table in ms access. I have set the data type of ID to Auto Number in MS-access. In java when I try to update a record. the netBeans IDE gives me the error of " data type missmatch in criteria expression". But when I changed the ID number that was not in the table already it works well. The code is below. String sql = "Update table1 set price ='" + txtPrice.getText() + "', quantity='" + txtQuantity.getText() + "', description='" + txtDescription.getText() + "' where id= " + txtid.getText() + ""; try { pst = conn.prepareStatement(sql); pst.executeUpdate(); JOptionPane.showMessageDialog(null, "Updated"); UpdateJTable(); } catch (Exception e) { JOptionPane.showMessageDialog(null, e); }

  • Many-to-one relationship in SQLAlchemy

    - by Arrieta
    This is a beginner-level question. I have a catalog of mtypes: mtype_id name 1 'mtype1' 2 'mtype2' [etc] and a catalog of Objects, which must have an associated mtype: obj_id mtype_id name 1 1 'obj1' 2 1 'obj2' 3 2 'obj3' [etc] I am trying to do this in SQLAlchemy by creating the following schemas: mtypes_table = Table('mtypes', metadata, Column('mtype_id', Integer, primary_key=True), Column('name', String(50), nullable=False, unique=True), ) objs_table = Table('objects', metadata, Column('obj_id', Integer, primary_key=True), Column('mtype_id', None, ForeignKey('mtypes.mtype_id')), Column('name', String(50), nullable=False, unique=True), ) mapper(MType, mtypes_table) mapper(MyObject, objs_table, properties={'mtype':Relationship(MType, backref='objs', cascade="all, delete-orphan")} ) When I try to add a simple element like: mtype1 = MType('mtype1') obj1 = MyObject('obj1') obj1.mtype=mtype1 session.add(obj1) I get the error: AttributeError: 'NoneType' object has no attribute 'cascade_iterator' Any ideas?

  • Unique constraint with nullable column

    - by Álvaro G. Vicario
    I have a table that holds nested categories. I want to avoid duplicate names on same-level items (i.e., categories with same parent). I've come with this: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci Unluckily, category_name_UNIQUE does not enforce my rule for root level categories (those where parent_id is NULL). Is there a reasonable workaround?

  • Log Shipped but Won't Update

    - by MooCow
    I'm currently taking the MS SQL 2K5 Admin course at a local college and ran into a problem with the Log Shipping part. My setup is the following: Windows 7 x64 SQL 2005 SP3 2 SQL server instances on the same machine Log Shipping settings: Performed full then log back up of Primary Manually restore on Secondary in STANDBY MODE Insert a new record into the table Set up Log Shipping on Primary using SQL Authenication login to connect to the Secondary Set up timers and copy destination on Secondary Monitoring instance not being used I set up a shared folder for WORKGROUP so both instances on the machine can read & write to it. I can see transaction logs generated and copied as defined by the Transaction Shipping wizard. However, the specified table on the Secondary instance is not updating.

  • Reusing an anonymous parameter in a prepared statement

    - by Chris Lieb
    I am customizing the insert SQL generated by hibernate and have hit an issue. When Hibernate generates the query by itself, it inserts data into the first two columns of the table, but this causes a database error since all four columns of the table are non-nullable. For the insert to be performed properly, it must insert the same data into two columns of the new record. This means that I need Hibernate to bind the same data to two different parameters in the query (prepared statement) that I am writing. Is there some SQL syntax that allows me to refer to anonymous parameters bound to a prepared statement in an order different from which they are bound? Details REF_USER_PAGE_XREF ---------------------------------------- PK FK1 | NETWORK_ID | VARCHAR2(100) PK FK1 | PAGE_PATH | VARCHAR2(1000) | USER_LAST_UPDT | VARCHAR2(100) | TMSP_LAST_UPDT | DATE insert into REF_USER_ROLE_XREF( NETWORK_ID, PAGE_PATH, TMSP_LAST_UPDT, USER_LAST_UPDT) values ( ?, /* want to insert the same data here */ ?, ?, /* and here */ (select to_char(sysdate, 'DD-MON-YY') from dual) I want to insert the same data into the first and third anonymous parameters.

  • SQL Server 2008 + expensive union all

    - by Tim Mahy
    Hi al, we have 5 tables over which we should query with user search input throughout a stored procedure. We do a union all of the similar data inside a view. Because of this the view can not be materialized. We are not able to change these 5 tables drastically (like creating a 6th table that contains the similar data of the 5 tables and reference that new one from the 5 tables). The query is rather expensive / slow what are our other options? It's allowed to think outside the box. Unfortunately I cannot give more information like the table/view/SP definition because of customer confidentiality... greetings, Tim

  • how to write T-SQL to compare and copy data?

    - by George2
    Hello everyone, I have two SQL Server 2008 Enterprise databases (on two machines), and one of the databases is master database and another database is slave database. I want to transfer update from a table in source database to a table in destination database (two tables are of the same schema, both of them are using a single column as unique primary key). The transfer rule is (in short, the rule is keeping the destination database the same as source database because of the update of the source database), if there is a new row in source database but not in destination database, insert the row in destination database; if a row not exists in source database but exists in destination database, delete the row in destination database; if a row's content (i.e. columns other than primary key columns) changes in source database, update the new content into destination database. thanks in advance, George

  • Notify a content resolver when normal sql insert or update

    - by user1400538
    I have created a small content provider (which I only use to query a db table and fetch some value). I have confirmed that the provider works fine. The table values get updated on a regular basis through normal sql insertions(and not through anycontent provider) Whenever an insert/update or delete occurs through a normal sqlite operation as mentioned above, I need to notify the content resolvers which was written to communicate with the content provider just for quering database and fetch some values. Is this, possible? If yes what need to be done? Any help is appreciated.

  • Subsonic foreign key returning collection?

    - by Shaul
    I'm just writing my first "Hello World" program using Subsonic, for which I've thrown together a simple little Customer/Invoice/InvoiceItem/Product database. The connection was successfully made to the DB, and it generated all the right ActiveRecord classes. But for some reason, the Invoice class has a property called Customers, which returns a collection of Customer objects, even though the Invoice table has a CustomerID field which has a foreign key to the Customer table. I would have expected a Customer property returning a single Customer object. I must be doing something wrong - but what?

  • Problems with UITableView when loading the view into the main window

    - by GuidoMB
    I've created a sub class of UITableViewController named LoginViewController with the XIB file using XCode. Then I opened the XIB file with IB and set the table's style to grouped. Finally I wrote the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]]; [window addSubview: loginViewController.view]; window.backgroundColor = [UIColor blueColor]; [window makeKeyAndVisible]; [window layoutSubviews]; } I set the window's background color to blue for you to see what the problem is. I put a link to the screenshot If I don't use the table style grouped the problem does not occur

  • Getting started with SQLite (Android)

    - by Tarmon
    Hey Everyone, I have limited SQL background, basically a small amount of manipulation through HTML and mostly with pre-existing databases. What I am trying to do is set up a database that will store time information for bus routes. So basically I have different routes with stops for each route and then a list of times that the bus arrives at each stop. Here is an example of a table of times from their website: Link. I am wondering what would be the best way to layout my database/tables? Also what is the purpose of the _id field in each table? Thanks, Rob! P.S. Sorry if my lack of knowledge on the subject has caused me to post a duplicate question.
