• Problem while redirecting user after registration

  - by Eternal Learner

  I am creating a simple website . My situation is like this. After registering an user, I want to redirect the user after say 3 seconds to a main page(if the registration succeeds) . The code I have now is as below $query = "INSERT INTO Privileges VALUES('$user','$password1','$role')"; $result = mysql_query($query, $dbcon) or die('Registration Failed: ' . mysql_error()); print 'Thanks for Registering , You will be redirected shortly'; ob_start(); echo "Test"; header("Location: http://www.php.net"); ob_flush() I get the error message Warning: Cannot modify header information - headers already sent by (output started at/home/srinivasa/public_html/ThanksForRegistering.php:27) in /home/srinivasa /public_html/ThanksForRegistering.php on line 35. What do I need to do now ?

• Getting records from a table based on a filter field and Between but also having the OR login for mu

  - by Pentium10

  I have a this table, where I store multiple ids and an age range (def1,def2) CREATE TABLE "template_requirements" ("_id" INTEGER NOT NULL, "templateid" INTEGER, "def1" VARCHAR(255), "def2" VARCHAR(255), PRIMARY KEY("_id")) Having values such as: templateid | def1 | def2 100 | 7 | 25 200 | 40 | 90 300 | 7 | 25 300 | 40 | 60 as you see for templateid 300 we have an or logic: age between 7 and 25 or age between 40 and 60. I want to get all the template ids that are not for a certain age like 25... What's the problem? If I run a query like this one: SELECT group_concat(templateid) FROM template_requirements where and '25' not between cast(def1 as integer) and cast(def2 as integer) it returns 200, 300, which is wrong, as the 300 matched on row 40 to 60, but shouldn't be included in the result as we have a condition with same templateid 7 to 25 that fails the not beetween stuff. How would be the correct query in SQLite, I would like to keep the group_concat stuff.

• MySQL -- How to do this better?

  - by Andrew

  $activeQuery = mysql_query("SELECT count(`status`) AS `active` FROM `assignments` WHERE `user` = $user_id AND `status` = 0"); $active = mysql_fetch_assoc($activeQuery); $failedQuery = mysql_query("SELECT count(`status`) AS `failed` FROM `assignments` WHERE `user` = $user_id AND `status` = 1"); $failed = mysql_fetch_assoc($failedQuery); $completedQuery = mysql_query("SELECT count(`status`) AS `completed` FROM `assignments` WHERE `user` = $user_id AND `status` = 2"); $completed = mysql_fetch_assoc($completedQuery); There has to be a better way to do that, right? I don't know how much I need to elaborate as you can see what I'm trying to do, but is there any way to do all of that in one query? I need to be able to output the active, failed, and completed assignments, preferably in one query.

• Setting an empty default value for a char-column in MySQL?

  - by user281434

  Hi In phpMyAdmin I have a char(32) column that has no default value(ie. Default: None). When I try to insert data through a SQL query, it throws out an error saying that the column "doesn't have a default value". I need it to be empty, so instead I've just set it's default value as "As defined: " and then nothing in the value field. Is this a bad idea? And is it any better than simply throwing in an empty value for the column in the SQL query? Thanks for your time.

• PHP Time Zone Adjustment

  - by emailq

  I have a time that is being sent to me in UTC time, but I want to adjust it so its the outer edges of the days on East Coast time (EST/EDT). That is, I want the user to be able to enter in EDT/EST centric dates, and have it query with the UTC correct dates. $start_date and $end_date are MM/DD/YYYY formatted dates passed via a GET variable. $start_date = date('Y-m-d 00:00:00', $start_date); $end_date = date('Y-m-d 23:59:59', $end_date); These dates are for use in a database query, whose times are stored in UTC time. So, I want the start date to be the day before at 8pm or 7pm, depending on daylight savings, and then to end at 7:59:59 or 6:59:59, again depending on daylight savings. How would I do that?

• How to easily get the unmatched condition in mysql

  - by leivli

  I have a "server" table which has a column named 'SN' in mysql, when do query to retrive servers with some sns from 'sn1' to 'sn10000', we can: select * from server where sn in ('sn1','sn2','sn3',...'sn10000'); If there is only one sn in 'sn1'-'sn10000' which not exists in database, then the query above will retrive 9999 rows of result. The question is how can I easily get which one in 'sn1'-'sn10000' is not exists in database except the additional work, such as handling the result with shell script etc. I have an ugly sql like below can use: select * from (select 'sn1' as sn union select 'sn2' union select 'sn3' .... union select 'sn10000') as SN where not exists (select id from server where server.sn=SN.sn); Is Anyone has other better methods? Thanks.

  I am inserting data in MySQL data base but in field it does not insert data.

• Is there a way to update a database when installing/upgrading an app?

  - by Adam

  I have a main application, and a bunch of sub-applications (they are separate apps, which do not appear on the android home dashboard). I was planning on having a SQLite DB which the main app maintains, and get a list of available sub-apps from. Is there a way to update this main database as the user installs the sub-apps? Two alternative I was thinking of include: User installs the sub-apps via the main app, which would then update the DB. Rather than use the DB to find all installed sub-apps, have each sub-app declare a category, and use intents to query for all applications which match that query (is this even possible? if so, advice is welcomed). Thanks!

• Are these 2 sql queries equivalent in all respects (e.g. estimated and actual execution plan)?

  - by Xerion

  Are query 1) == 2) in terms of estimated query plan AND actual plan? (can statistics affect the actual plan here, ever?) declare @cat int -- input param from prc ... 1) select * from A as a join B as b on b.id = a.id on b.cat = @cat join C as c on c.fid = b.fid on c.cat = @cat where a.cat = @cat 2) select * from A as a join B as b on b.id = a.id on b.cat = a.cat join C as c on c.fid = b.fid on c.cat = b.cat where a.cat = @cat It seems to me that these should logically be equivalent and the execution plan should always be the same regardless of actual difference in tables. And adding more conditions either in join, or where, or add more tables to join shouldn't change this. Are there cases this is not true?

• What is the maximum length of a string parameter to Stored procedure?

  - by padmavathi

  I have a string of length 1,44,000 which has to be passed as a parameter to a stored procedure which is a select query on a table. When a give this is in a query (in c# ) its working fine.

• User activity vs. System activity on the Index Usage Statistics report

  - by Zachary G Jensen

  I recently decided to crawl over the indexes on one of our most heavily used databases to see which were suboptimal. I generated the built-in Index Usage Statistics report from SSMS, and it's showing me a great deal of information that I'm unsure how to understand. I found an article at Carpe Datum about the report, but it doesn't tell me much more than I could assume from the column titles. In particular, the report differentiates between User activity and system activity, and I'm unsure what qualifies as each type of activity. I assume that any query that uses a given index increases the '# of user X' columns. But what increases the system columns? building statistics? Is there anything that depends on the user or role(s) of a user that's running the query?

• SQL Server - how to determine if indexes aren't being used?

  - by rwmnau

  I have a high-demand transactional database that I think is over-indexed. Originally, it didn't have any indexes at all, so adding some for common processes made a huge difference. However, over time, we've created indexes to speed up individual queries, and some of the most popular tables have 10-15 different indexes on them, and in some cases, the indexes are only slightly different from each other, or are the same columns in a different order. Is there a straightforward way to watch database activity and tell if any indexes are not hit anymore, or what their usage percentage is? I'm concerned that indexes were created to speed up either a single daily/weekly query, or even a query that's not being run anymore, but the index still has to be kept up to date every time the data changes. In the case of the high-traffic tables, that's a dozen times/second, and I want to eliminate indexes that are weighing down data updates while providing only marginal improvement.

• linq2sql left join with "multiselect"

  - by just_azho

  Hi, folks I'm trying to achieve following by linq2sql, but not successful. I've Member and Reference tables. DB is design in such a manner that Member can have multiple (=0) References. What I want as a result of query is, list (rows) of members, where all references of the member are "collected" in one column. What I had achieved is following query, but for this one there exist a row for each Reference. var refs = (from m in db.Members join r in db.References on m.PID equals r.PID into g from o in g.DefaultIfEmpty() select new { member = m, name = (o == null ? "" : o.NameSurname) }); I feel I need to insert SelectMany somewher :) Could you please give hints on achieving the goal?

• Why is Hibernate not loading a column?

  - by B.R.

  I've got an entity with a few properties that gets used a lot in my Hibernate/GWT app. For the most part, everything works fine, but Hibernate refuses to load one of the properties. It doesn't appear in the query, despite being annotated correctly in the entity. The relevant portion of the entity: @Column(name="HasSubSlots") @Type(type="yes_no") public boolean hasSubSlotSupport() { return hasSubSlotSupport; } And the generated SQL query: Hibernate: /* load entities.DeviceModel */ select devicemode0_.DevModel as DevModel1_0_, devicemode0_.InvModelName as InvModel2_1_0_ from DeviceModels devicemode0_ where devicemode0_.DevModel=? Despite the fact that I refer to that property, it's never loaded, lazily or not, and the getter always returns false. Any ideas on how I can dig deeper into this, or what might be wrong?

• comparing rows on a mysql table

  - by user311324

  Ok here's the deal I got one table with a bunch of client information. Each client makes up to one purchase a year which is represented by an individual row. there's a column for the year and there's a column the contains a unique identifier for each client. What I need to do is to construct a query that takes last year and this year and shows me which clients were here made a purchase last year but not make a purchase this year. I also need to build a query that shows me which clients did not make a purchase last year and the year before last but did make a purchase this year.

• Row for each hour even if there is no record

  - by peku33

  I've got a trouble with creating mysql Query. My PHP script executes this query on each run: INSERT INTO Executes SET UserIp='%s' (%s is user IP) Executes table is: ExecuteId UNSIGNED BIGINT AI PRIMARY Date TIMESTAMP DEFAULT CURRENT_TIMESTAMP INDEX UserIp CHAR(24) ... | Some Columns I want to retrive number of Executes in each hour. The most obvious solution would be: SELECT COUNT(*) as ExecutesNum, DATE(Date) as D, HOUR(Date) as H GROUP BY D, H And it works, BUT it does not create rows for hours where there were no executes. What should I modify to get result like: 1 | 2012-09-01 | 14 **0 | 2012-09-01 | 15** 11 | 2012-09-01 | 16 1 | 2012-09-01 | 17

• MySQL LEFT JOIN issue with three WHERE statements

  - by jhat

  I am building a note taking app for myself with tag filtering functions, but am having an issue when trying to grab notes with the tags. The tag filter needs to use AND not IN, because it will help better narrow down what I am looking for. My tables are configured like this: + notes note_id | note_title | note_uid + tags tag_id | tag_title + notes_tags nt_id | nt_note_id | nt_tag_id The notes_tags table keeps track of all notes' tags. I am not worried about returning any information about tags, so here is an example LEFT JOIN I am using currently to only get notes with only 1 tag. SELECT * FROM notes_tags LEFT JOIN notes ON note_id = nt_note_id WHERE note_uid IN ( 1 ) AND nt_tag_id = 10 This query runs perfect, it grabs all of the notes with that single tag. However, I am having issues "pinpointing" my notes using a query like this: SELECT * FROM notes_tags LEFT JOIN notes ON note_id = nt_note_id WHERE note_uid IN ( 1 ) AND nt_tag_id = 10 AND nt_tag_id = 11 What am I doing wrong with the syntax?

• C# LINQ join With Just One Row

  - by Soo

  I'm trying to make a query that grabs a single row from an SQL database and updates it. TableA AId AValue TableB BId AId BValue Ok, so TableA and TableB are linked by AId. I want to select a row in TableB based on AValue using a join. The following query is what I have and only grabs a value from TableB based on AId, I just don't know how to grab a row from TableB using AValue. I know you would need to use a join, but I'm not sure how to accomplish that. var row = DbObject.TableB.Single(x => x.AId == 1) row.BValue = 1; DbObject.SubmitChanges();

• Optimal search queries

  - by Macros

  Following on from my last question http://stackoverflow.com/questions/2788082/sql-server-query-performance, and discovering that my method of allowing optional parameters in a search query is sub optimal, does anyone have guidelines on how to approach this? For example, say I have an application table, a customer table and a contact details table, and I want to create an SP which allows searching on some, none or all of surname, homephone, mobile and app ID, I may use something like the following: select * from application a inner join customer c on a.customerid = a.id left join contact hp on (c.id = hp.customerid and hp.contacttype = 'homephone') left join contact mob on (c.id = mob.customerid and mob.contacttype = 'mobile') where (a.ID = @ID or @ID is null) and (c.Surname = @Surname or @Surname is null) and (HP.phonenumber = @Homphone or @Homephone is null) and (MOB.phonenumber = @Mobile or @Mobile is null) The schema used above isn't real, and I wouldn't be using select * in a real world scenario, it is the construction of the where clause I am interested in. Is there a better approach, either dynamic sql or an alternative which can achieve the same result, without the need for many nested conditionals. Some SPs may have 10 - 15 criteria used in this way

• Trying to exlcude VTI* paths in MSIDXS sql select statement

  - by Catdirt

  Hi, using a c# asp.net page, building a SQL query string to run against an index server catalog: string SQL = "SELECT doctitle, vpath, Path, Write, Size, Rank "; SQL += "FROM \"" + strCatalog + "\"..SCOPE() "; SQL += "WHERE"; SQL += " CONTAINS(Contents, '" + strQP + "') "; SQL += "AND NOT CONTAINS(Path, '\"_vti_\"') "; SQL += "AND NOT CONTAINS(FileName, '\".ascx\" OR \".config\" OR \".css\"') "; SQL += "ORDER BY Rank DESC"; Seems to work fine, except it will return results in the _vti_ directories which I am trying to avoid. Edit: All but asked question, so to be technical: How can I search the index and have it not return files from the vti folders? Switching to use an ixsso query object is possible, but i'd rather avoid it for this particular instance.

• C++ and virtual methods overriding

Why not "profiles"?

• How to change particular column entries in a mysql table when uploading data from csv file?

  - by understack

  I upload data into a mysql table from csv file in a standard way like this: TRUNCATE TABLE table_name; load data local infile '/path/to/file/file_name.csv' into table table_name fields terminated by ',' enclosed by '"' lines terminated by '\r\n' (id, name, type, deleted); All 'deleted' column entries in csv file has either 'current' or 'deleted' value. Question: When csv data is being loaded into table, I want to put current date in table for all those corresponding 'deleted' entries in csv file. And null for 'current' entries. How can I do this? Example: csv file: id_1, name_1, type_1, current id_2, name_1, type_2, deleted id_3, name_3, type_3, current Table after loading this data should look like this: id_1, name_1, type_1, null id_2, name_1, type_2, 2010-05-10 id_3, name_3, type_3, null Edit Probably, I could run another separate query after loading csv file. Wondering if it could be done in same query?

• "Remember" last three MySql queries; Cookie, passed variable or other method?

  - by Camran

  I have a classified website, with pretty sophisticated searching, and I am about to implement a function where the last three queries is displayed for the user, so that the user can go back easier through the queries. This because for each query the user has to provide a lot of input. I have four questions for you: I wonder, how can I save the actual query (SELECT * FROM etc etc)...? Do I need to add some form of encryption to be on the safe side? How will this affect performance? (I don't like the fact that cookies slow websites down) Anything else to think about? If you need more input, let me know... Btw, the website is PHP based. Thanks
