  • Objective-C: how to splt a string constant across multiple lines

    - by Ilya
    Hi, I have a pretty long sqlite query: const char *sql_query = "SELECT statuses.word_id FROM lang1_words, statuses WHERE statuses.word_id = lang1_words.word_id ORDER BY lang1_words.word ASC"; How can I break it in a number of lines to make it easier to read? If I do the following: const char *sql_query = "SELECT word_id FROM table1, table2 WHERE table2.word_id = table1.word_id ORDER BY table1.word ASC"; I am getting a error. Is there a way to write queries in multiple lines? Thank you.

    - by garcon1986
    Hello, I want to use a drop down list, every time i click the content in it, different pictures will show up.

  • Placing the where condition

    - by user182944
    I came up with the below query: SELECT ROOMNO,BUILDINGNO FROM MRM_ROOM_DETAILS WHERE ROOMID IN ( SELECT distinct roomid FROM MRM_BOOKING_DETAILS WHERE (CHECKIN NOT BETWEEN '2012-04-13 09:50:00' AND '2012-04-13 10:20:00') AND (CHECKOUT NOT BETWEEN '2012-04-13 09:50:00' AND '2012-04-13 10:20:00')) AND CAPACITY > 15 AND PROJECTIONSTATUS = 'NO'; I need to place this query in the method SQLiteDatabase.query() and fetch the rows accordingly. I am not able to understand how to place this big where condition (which contains a sub-query as well) in place of the "String selection" i.e. 3rd parameter of the method. Shall i simple write the entire where part(including the sub-query) as a string in the 3rd parameter or else there is some other better way for doing the same? Please suggest me the best way to do the same. Regards,

  • Duplicate / Copy records in the same MySQL table

    - by Digits
    I have been looking for a while now but I can not find an easy solution for my problem. I would like to duplicate a record in a table, but of course, the unique primary key needs to be updated. I have this query: INSERT INTO invoices SELECT * FROM invoices AS iv WHERE iv.ID=XXXXX ON DUPLICATE KEY UPDATE ID = (SELECT MAX(ID)+1 FROM invoices) the problem is that this just changes the ID of the row instead of copying the row. Does anybody know how to fix this ? Thank you verrry much, Digits //edit: I would like to do this without typing all the field names because the field names can change over time.

  • How to access Oracle system tables from inside of a PL/SQL function or procedure?

    - by mjumbewu
    I am trying to access information from an Oracle meta-data table from within a function. For example (purposefully simplified): CREATE OR REPLACE PROCEDURE MyProcedure IS users_datafile_path VARCHAR2(100); BEGIN SELECT file_name INTO users_datafile_path FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; END MyProcedure; / When I try to execute this command in an sqlplus process, I get the following errors: LINE/COL ERROR -------- ----------------------------------------------------------------- 5/5 PL/SQL: SQL Statement ignored 6/12 PL/SQL: ORA-00942: table or view does not exist I know the user has access to the table, because when I execute the following command from the same sqlplus process, it displays the expected information: SELECT file_name FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; Which results in: FILE_NAME -------------------------------------------------------------------------------- /usr/lib/oracle/xe/oradata/XE/users.dbf Is there something I need to do differently?

  • Problem using OLEDBCOMMANDBUILDER.

    - by Lullly
    So, here it goes: I need to copy data from table in access database, in another table from another access database. Column names from tables are the same, except the fact that the FROM table has 5 columns, the TO table has 6. here is my code: dsFrom.Clear() dsTO.Clear() daFrom = Nothing daTO = Nothing conn_string1 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="etc.mdb;" conn_string2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="database.mdb;" query1 = "Select * from nomenclator_produse" query2 = "Select * from nomenclator_produse" Conn1 = New OleDbConnection(conn_string1) conn2 = New OleDbConnection(conn_string2) Conn1.Open() conn2.Open() daFrom = New OleDbDataAdapter(query1, Conn1) daTO = New OleDbDataAdapter(query2, conn2) daFrom.AcceptChangesDuringFill = False dsFrom.HasChanges() daFrom.Fill(dsFrom, "nomenclator_Produse") dsFrom.HasChanges() Dim cb = New OleDbCommandBuilder(daFrom) dsTO = dsFrom.Copy daTO.UpdateCommand = cb.GetUpdateCommand daTO.InsertCommand = cb.GetInsertCommand daTO.Update(dsTO, "nomenclator_produse") Because the FROM table has 5 rows and the other has 6, i'm trying to use the InsertCommand generated by the DataAdapter of the first table. It works, only that it inserts the data from the FROMTABLE in the same FROMTABLE, instead of TOTABLE. :| please help me :(

  • NHibernate: References still being eagerly selected after specifying AddJoin

    - by cbp
    I have a query which is something like this: Session.CreateSQLQuery( @"SELECT f.*, b.*, z.* FROM Foo f LEFT OUTER JOIN Bar b ON b.Id = f.BarId LEFT OUTER JOIN Zar z ON z.Id = b.ZarId" ) .AddEntity("f", typeof(Foo)) .AddJoin("b", "f.BarId") .AddJoin("z", "f.ZarId") .List<Foo>(); The problem is that I am still getting hundreds of SELECT requests made to the Zar table, even though I have specified that Zar should be joined. As far as I am aware the only relationship is Foo-Bar-Zar, i.e. the reference to Zar is not occurring anywhere else. Is my understanding of AddJoin correct? What could be going wrong? List item

  • Why is order important in moving from tab to tab programmatically (and new in 1.8.10

    - by Bruce
    Hi folks, Up until I updated to jquery-ui-1.8.10 (already using jQuery 1.5), the following code has worked as expected: case 'baseeditor': $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); $("#prolearn").tabs("select",1); break; case ... The tab is fueled and then focus is moved from tab0 (from where the ajax call is initiated) to tab1. Now, that code won't work, but this version does: case 'baseeditor': $("#prolearn").tabs("select",1); $('#tab1').html(responseText).fadeIn(500, function() { ... load the contents of the tab and stuff... }); break; case ... Can someone explain the difference - have I just been lucky getting away with my original version? Thanks/Bruce

  • Performance: Subquerry or Joining

    - by Auro
    HelloHello I got a little Question about Performance of a Subquerry /Joining another table INSERT INTO Original.Person ( PID, Name, Surname, SID ) ( SELECT ma.PID_new , TBL.Name , ma.Surname, TBL.SID FROM Copy.Person TBL , original.MATabelle MA WHERE TBL.PID = p_PID_old AND TBL.PID = MA.PID_old ); This is my SQL, now this thing runs around 1 million times or more. Now my question is what would be faster? if I change TBL.SID to (Select new from helptable where old = tbl.sid) or if I add helptable to the from and do the joining in the where? greets Auro

  • Text in gtk.ComboBox without active item

    - by Yotam
    The following PyGTk code, gives a combo-box without an active item. This serves a case where we do not want to have a default, and force the user to select. Still, is there a way to have the empty combo-bar show something like: "Select an item..." without adding a dummy item? import gtk import sys say = sys.stdout.write def cb_changed(w): say("Active index=%d\n" % w.get_active()) topwin = gtk.Window() topwin.set_title("No Default") topwin.set_size_request(0x100, 0x20) topwin.connect('delete-event', gtk.main_quit) vbox = gtk.VBox() ls = gtk.ListStore(str, str) combo = gtk.ComboBox(ls) cell = gtk.CellRendererText() combo.pack_start(cell) combo.add_attribute(cell, 'text', 0) combo.connect('changed', cb_changed) ls.clear() map(lambda i: ls.append(["Item-%d" % i, "Id%d" % i]), range(3)) vbox.pack_start(combo, padding=2) topwin.add(vbox) topwin.show_all() gtk.main() say("%s Exiting\n" % sys.argv[0]) sys.exit(0)

  • Why is Zend Framework (Zend_Db_table) rejecting this SQL Query?

    - by Michael T. Smith
    I'm working on a simple JOIN of two tables (urls and companies). I am using this query call: print $this->_db->select()->from(array('u' => 'urls'), array('id', 'url', 'company_id')) ->join(array('c' => 'companies'), 'u.company_id = c.id'); which is out putting this query: SELECT `u`.`id`, `u`.`url`, `u`.`company_id`, `c`.* FROM `urls` AS `u` INNER JOIN `companies` AS `c` ON u.company_id = c.id Now, I'd prefer the c.* to not actually appear, but either way it doesn't matter. ZF dies with this error: SQLSTATE[42000]: Syntax error or access violation: 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 '' at line 1" but I can run that query perfectly fine in my MySQL CLI. Any ideas how to fix up this query?

  • Javascript returns Nan in IE, FF ok

    - by user350184
    im very new to javascript, and writing this script to add up a shopping cart and print out subtotals and totals. it works in FF but not in IE. this function is called by onclick of one of three select options with a value of 0-25. it is in a js file called in the head. what it does is get the selected values as variables, parseint them, adds and multiplies, and changes the innerHTML of the table to reflect the subtotals, and total. FF does it great, but IE gives Nan. ive tried rewriting it a number of different ways, and many translations still work in FF but not IE8. ive made sure the variables and form id's arent repeated. function gen_invoice() { var scount = parseInt(document.shopcart.studentcount.value, 10); var ycount = parseInt(document.shopcart.youthcount.value, 10); var fcount = parseInt(document.shopcart.facultycount.value, 10); //html output source is 3 selects like this, with diff ids and names: //<select name="studentcount" id="studentcount"> //<option onclick="gen_invoice()" value="0">0 </option></select> var cardcost = parseInt(document.shopcart.cardprice.value, 10); //cardcost comes from hidden input value: //<input type="hidden" id="cardprice" name="cardprice" value="25"> var totalsum = scount + ycount + fcount; var grandtotal = totalsum * cardcost; document.getElementById('s_price').innerHTML = scount * cardcost; document.getElementById('y_price').innerHTML = ycount * cardcost; document.getElementById('f_price').innerHTML = fcount * cardcost; document.getElementById('grand').innerHTML = grandtotal; //.... } ...after this there are 3 long loops for writing out some other forms, but they dont work in IE either because they depend on the selected values to be an integer. this part happens first and returns Nan, so im sure the problem is here somwhere. I have literally hit my head on the table over this. You can imagine how frustrating it is to be able to write the entire rest of the site beautifully, but then fail at adding 3 numbers together. help please!

  • How to retrieve base class only (entity framework)?

    - by Juvaly
    Hi All, I've been scratching my head here for a while now... I have a Consumer class and a BillableConsumer class that inherits Consumer. They are both a part of the Consumers set. The problem is that this following query: Consumer consumer = (from c in _ctx.Consumers where c.ID = id select c).First(); returns a BillableConsumer instance! Just the same as this query: BillableConsumer bconsumer = (from c in _ctx.Consumers.OfType<BillableConsumer>() where c.ID = id select c).First(); How can I return an instance of just the base class? (these are separate tables in the data store).

  • How to get variable value from inside a stored procedure in DB2?

    - by Sylvia
    This seems like it should be very easy...anyway, it is in MS SQL Server In a DB2 stored procedure, how can I just get the value of a variable? Say I have the following stored procedure: CREATE PROCEDURE etl.TestABC( ) LANGUAGE SQL BEGIN declare Stmt varchar(2048); set Stmt = 'this is a test'; -- print Stmt; -- select Stmt; return 0; END @ I'd like to print out the value of Stmt after I set it. Print doesn't work, select doesn't work. Somebody said I have to insert it to a table first, and then get it after I run the stored procedure. Is this really necessary? Thanks, Sylvia EDIT: I should have made clearer that I want to see the value of Stmt each time after I set it, and I may need to set it multiple times within the same stored procedure.
