  • Container for database-like searches

    - by Milan Babuškov
    I'm looking for some STL, boost, or similar container to use the same way indexes are used in databases to search for record using a query like this: select * from table1 where field1 starting with 'X'; or select * from table1 where field1 like 'X%'; I thought about using std::map, but I cannot because I need to search for fields that "start with" some text, and not those that are "equal to". I could create a sorted vector or list and use binary search (breaking the set in 2 in each step by reading the element in the middle and seeing if it's more or less than 'X'), but I wonder if there is some ready-made container I could use without reinventing the wheel?

  • Mysql - Grouping the result based on a mathematical operation and SUM() function

    - by SpikETidE
    Hi all... I'm having the following two tables... Table : room_type type_id type_name no_of_rooms max_guests rate 1 Type 1 15 2 1254 2 Type 2 10 1 3025 Table : reservation reservation_id start_date end_date room_type booked_rooms 1 2010-04-12 2010-04-15 1 8 2 2010-04-12 2010-04-15 1 2 Now... I have this query SELECT type_id, type_name FROM room_type WHERE id NOT IN (SELECT room_type FROM reservation WHERE start_date >= '$start_date' AND end_date <= '$end_date') What the query does is it selects the rooms that are not booked between the start date and end date. Also, as you can see from the reservation table, we also have 'number of rooms booked between the two dates' factor also... I need to add this 'no.of booked rooms between the two dates' factor also in to the query... The query should return the type of rooms for which at least one room is free between the two dates. I worked out the logic but just can't represent it as a query....! How will you do this...? Thanks for your suggestions..!

  • Cannot add an entity that already exists. (LINQ to SQL)

    - by Vicheanak
    Hello guys, in my database there are 3 tables CustomerType CusID EventType EventTypeID CustomerEventType CusID EventTypeID Dim db = new CustomerEventDataContext Dim newEvent = new EventType newEvent.EventTypeID = txtEventID.text db.EventType.InsertOnSubmit(newEvent) db.SubmitChanges() 'To select the last ID of event' Dim lastEventID = (from e in db.EventType Select e.EventTypeID Order By EventTypeID Descending).first() Dim chkbx As CheckBoxList = CType(form1.FindControl("CheckBoxList1"), CheckBoxList) Dim newCustomerEventType = New CustomerEventType Dim i As Integer For i = 0 To chkbx.Items.Count - 1 Step i + 1 If (chkbx.Items(i).Selected) Then newCustomerEventType.INTEVENTTYPEID = lastEventID newCustomerEventType.INTSTUDENTTYPEID = chkbxStudentType.Items(i).Value db.CustomerEventType.InsertOnSubmit(newCustomerEventType) db.SubmitChanges() End If Next It works fine when I checked only 1 Single ID of CustomerEventType from CheckBoxList1. It inserts data into EventType with ID 1 and CustomerEventType ID 1. However, when I checked both of them, the error message said Cannot add an entity that already exists. Any suggestions please? Thx in advance.

  • how to optimize an oracle query that has to_char in where clause for date

    - by panorama12
    I have a table that contains about 49403459 records. I want to query the table on a date range. say 04/10/2010 to 04/10/2010. However, the dates are stored in the table as format 10-APR-10 10.15.06.000000 AM (time stamp). As a result. When I do: SELECT bunch,of,stuff,create_date FROM myTable WHERE TO_CHAR (create_date,'MM/DD/YYYY)' >= '04/10/2010' AND TO_CHAR (create_date, 'MM/DD/YYYY' <= '04/10/2010' I get 529 rows but in 255.59 seconds! which is because I guess I am doing to_char on EACH record. However, When I do SELECT bunch,of,stuff,create_date FROM myTable WHERE create_date >= to_date('04/10/2010','MM/DD/YYYY') AND create_date <= to_date('04/10/2010','MM/DD/YYYY') then I get 0 results in 0.14 seconds. How can I make this query fast and still get valid (529) results?? At this point I can not change indexes. Right now I think index is created on create_date column

  • Issues querying Access '07 database in C#

    - by Kye
    I'm doing a .NET unit as part of my studies. I've only just started, with a lecturer that as kinda failed to give me the most solid foundation with .NET, so excuse the noobishness. I'm making a pretty simple and generic database-driven application. I'm using C# and I'm accessing a Microsoft Access 2007 database. I've put the database-ish stuff in its own class with the methods just spitting out OleDbDataAdapters that I use for committing. I feed any methods which preform a query a DataSet object from the main program, which is where I'm keeping the data (multiple tables in the db). I've made a very generic private method that I use to perform SQL SELECT queries and have some public methods wrapping that method to get products, orders.etc (it's a generic retail database). The generic method uses a separate Connect method to actually make the connection, and it is as follows: private static OleDbConnection Connect() { OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\Temp\db.accdb"); return conn; } The generic method is as follows: private static OleDbDataAdapter GenericSelectQuery( DataSet ds, string namedTable, String selectString) { OleDbCommand oleCommand = new OleDbCommand(); OleDbConnection conn = Connect(); oleCommand.CommandText = selectString; oleCommand.Connection = conn; oleCommand.CommandType = CommandType.Text; OleDbDataAdapter adapter = new OleDbDataAdapter(); adapter.SelectCommand = oleCommand; adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey; adapter.Fill(ds, namedTable); return adapter; } The wrapper methods just pass along the DataSet that they received from the main program, the namedtable string is the name of the table in the dataset, and you pass in the query you wish to make. It doesn't matter which query I give it (even something simple like SELECT * FROM TableName) I still get thrown an OleDbException, stating that there was en error with the FROM clause of the query. I've just resorted to building the queries with Access, but there's still no use. Obviously there's something wrong with my code, which wouldn't actually surprise me. Here are some wrapper methods I'm using. public static OleDbDataAdapter GetOrderLines(DataSet ds) { OleDbDataAdapter adapter = GenericSelectQuery( ds, "orderlines", "SELECT OrderLine.* FROM OrderLine;"); return adapter; } They all look the same, it's just the SQL that changes.

  • How can I combine xsl:attribute and xsl:use-attribute-sets to conditionally use an attribute set?

    - by Peter
    We have an xml node "item" with an attribute "style", which is "Header1". This style can change however. We have an attribute set named Header1 which defines how this should look in a PDF, generated through xsl:fo. This works (the use-attribute-sets is mentioned inline, in the fo:table-cell node): <xsl:template match="item[@type='label']"> <fo:table-row> <fo:table-cell xsl:use-attribute-sets="Header1"> <fo:block> <fo:inline font-size="8pt" > <xsl:value-of select="." /> </fo:inline> </fo:block> </fo:table-cell> </fo:table-row> </xsl:template> But this doesn't (using xsl:attribute, because the attribute @style can also be Header2 for example). It doesn't generate an error, the PDF is created, but the attributes aren't applied. <xsl:template match="item[@type='label']"> <fo:table-row> <fo:table-cell> <xsl:attribute name="xsl:use-attribute-sets"> <xsl:value-of select="@style" /> </xsl:attribute> <fo:block> <fo:inline font-size="8pt" > <xsl:value-of select="." /> </fo:inline> </fo:block> </fo:table-cell> </fo:table-row> </xsl:template> Does anyone know why? And how we could achieve this, preferably without long xsl:if or xsl:when stuff?

  • How to skip the invalid rows while inserting the data into Database

    - by Dinesh
    We have a statement., that is inserting some rows in a temporary table (say e.g., 10 rows), while inserting 5th row, it has some issue with one of the column format and giving an error and then it stopped inserting the rows. What I want is, it should skip the error rows and insert valid rows. For those error rows, it can skip that error column and insert with some null value & different status. create table #tb_pagecontent_value (pageid int,formid uniqueidentifier, id_field xml,fieldvalue xml,label_final xml) … … insert into #tb_pagecontent_xml select A.pageid,B.formid,A.PageData.query('/CPageDataXML/control') from Pagedata A inner join page B on A.PageId=B.PageId inner join FormAssociation C on B.FormId=C.FormId where B.pageid in (select pageId from jobs where jobtype='zba' and StatusFlag!=1) in the above e.g., I want to apply that logic. Any help is appreciated.

  • What does Apache need to support both mysqli and PDO?

    - by Nathan Long
    I'm considering changing some PHP code to use PDO for database access instead of mysqli (because the PDO syntax makes more sense to me and is database-agnostic). To do that, I'd need both methods to work while I'm making the changeover. My problem is this: so far, either one or the other method will crash Apache. Right now I'm using XAMPP in Windows XP, and PHP Version 5.2.8. Mysqli works fine, and so does this: $dbc = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password); echo 'Connected to database'; $sql = "SELECT * FROM `employee`"; But this line makes Apache crash: $dbc->query($sql); I don't want to redo my entire Apache or XAMPP installation, but I'd like for PDO to work. So I tried updating libmysql.dll from here, as oddvibes recommended here. That made my simple PDO query work, but then mysqli queries crashed Apache. (I also tried the suggestion after that one, to update php_pdo_mysql.dll and php_pdo.dll, to no effect.) Test Case I created this test script to compare PDO vs mysqli. With the old copy of libmysql.dll, it crashes if $use_pdo is true and doesn't if it's false. With the new copy of libmysql.dll, it's the opposite. if ($use_pdo){ $dbc = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password); echo 'Connected to database<br />'; $sql = "SELECT * FROM `employee`"; $dbc->query($sql); foreach ($dbc->query($sql) as $row){ echo $row['firstname'] . ' ' . $row['lastname'] . "<br>\n"; } } else { $dbc = @mysqli_connect($hostname, $username, $password, $dbname) OR die('Could not connect to MySQL: ' . mysqli_connect_error()); $sql = "SELECT * FROM `employee`"; $result = @mysqli_query($dbc, $sql) or die(mysqli_error($dbc)); while ($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) { echo $row['firstname'] . ' ' . $row['lastname'] . "<br>\n"; } } What does Apache need in order to support both methods of database query?

    I was under the impression this is valid SQLite syntax: SELECT *, (SELECT amount AS target FROM target_money WHERE start_year <= p.bill_year AND start_month <= p.bill_month ORDER BY start_year ASC, start_month ASC LIMIT 1) AS target FROM payments AS p; But I guess it's not, because SQLite returns this error: no such column: p.bill_year What's wrong with how I refer to p.bill_year? Yes, I am positive table payments hosts a column bill_year. Am I crazy or is this just valid SQL syntax? It would work in MySQL wouldn't it?? I don't have any other SQL present so I can't test others, but I thought SQLite was quite standardlike.

  • Slow query with unexpected scan

    - by zerkms
    Hello I have this query: SELECT * FROM SAMPLE SAMPLE INNER JOIN TEST TEST ON SAMPLE.SAMPLE_NUMBER = TEST.SAMPLE_NUMBER INNER JOIN RESULT RESULT ON TEST.TEST_NUMBER = RESULT . TEST_NUMBER WHERE SAMPLED_DATE BETWEEN '2010-03-17 09:00' AND '2010-03-17 12:00' the biggest table here is RESULT, contains 11.1M records. The left 2 tables about 1M. this query works slowly (more than 10 minutes) and returns about 800 records. executing plan shows clustered index scan over all 11M records. RESULT.TEST_NUMBER is a clustered primary key. if I change 2010-03-17 09:00 to 2010-03-17 10:00 - i get about 40 records. it executes for 300ms. and plan shows clustered index seek if i replace * in SELECT clause to RESULT.TEST_NUMBER (covered with index) - then all become fast in first case too. this points to hdd io issues, but doesn't clarifies changing plan. so, any ideas?
