• How do I list all tables in all databases in SQL Server in a single result set?

  - by msorens

  I am looking for T-SQL code to list all tables in all databases in SQL Server (at least in SS2005 and SS2008; would be nice to also apply to SS2000). The catch, however, is that I would like a single result set. This precludes the otherwise excellent answer from Pinal Dave: sp_msforeachdb 'select "?" AS db, * from [?].sys.tables' The above stored proc generates one result set per database, which is fine if you are in an IDE like SSMS that can display multiple result sets. However, I want a single result set because I want a query that is essentially a "find" tool: if I add a clause like WHERE tablename like '%accounts' then it would tell me where to find my BillAccounts, ClientAccounts, and VendorAccounts tables regardless of which database they reside in.

• the characters except 0x00-0x7F are not been shown when converted to "UTF-8" from "ISO-8859-1"

  - by Mike.Huang

  I need to get a string from URL request of brower, and then create a text image by requested text. I know the default encoding of the Java net transmission is "ISO-8859-1", it can works normally with all characters what defined in "ISO-8859-1". But when I request a multi-byte Unicode character (e.g. chinese or something like ¤?), then I need to decode it by "UTF-8" from "ISO-8859-1". My codes like: String reslut = new String(requestString.getBytes("ISO-8859-1"), "UTF-8"); Everything is fine, but I found some characters in ISO-8859-1 are not been shown now, which characters are 0x80 - 0xFF(defined in" ISO-8859-1"), i.e. the characters except 0x00-0x7F are not been shown when converted to "UTF-8" from "ISO-8859-1" Any other method can solve this query?

• MySQL insert at end of table

  - by Theopile

  Hello, I am using MySQL and PHP. I am having a problem with inserting a new item at the end of my table. When I insert the new item appears after the last created item, but I want it to be entered at the bottom of the table. Suppose that I have a table id=int,Primary Key and album=string and the table is: Wrath Crack The Skye Enter Shikari What would the MySQL query be if php variable $album=myAlbum was to be inserted next, at the end of the table, and with the appropriate id? Thanks

• zfdatagrid : how to set the relative order of columns?

  - by user522350

  To those of you who are familiar with zfdatagrid for the Zend framework: I got a recordset by a JOIN query, say from tables s and t, now I want to set the order in which the columns appear in the deployed table. For example, 5th column of table t to appear at the leftmost side, then 3rd column of table s, then 2nd column of table t, then 4th column of table s. How do I do this? Whatever I tried, it always shows first the columns of the left table of the JOIN, then the columns of the right table of the JOIN. I only know how to tell it which columns to show, but not their order. Thanks!

• How to exclude results with get_object_or_404?

  - by googletorp

  In Django you can use the exclude to create SQL similar to not equal. An example could be. Model.objects.exclude(status='deleted') Now this works great and exclude is very flexible. Since I'm a bit lazy, I would like to get that functionality when using get_object_or_404, but I haven't found a way to do this, since you cannot use exclude on get_object_or_404. What I want is to do something like this: model = get_object_or_404(pk=id, status__exclude='deleted') But unfortunately this doesn't work as there isn't an exclude query filter or similar. The best I've come up with so far is doing something like this: object = get_object_or_404(pk=id) if object.status == 'deleted': return HttpResponseNotfound('text') Doing something like that, really defeats the point of using get_object_or_404, since it no longer is a handy one-liner. Alternatively I could do: object = get_object_or_404(pk=id, status__in=['list', 'of', 'items']) But that wouldn't be very maintainable, as I would need to keep the list up to date. I'm wondering if I'm missing some trick or feature in django to use get_object_or_404 to get the desired result?

• Opening an Excel file in c#

  - by Jan de Jager

  So there are a lot of questions regarding this method on SO, but none seem to answer my question. I firstly had an issue with the connectionstring (although it seems to work in other areas of my code correctly). This was resolved easily. Now the issue is with a simple SELECT query via a OLEDBCommand (Text) that keeps popping up the following error? "SELECT [Opportunity#],[BidManager],[Prob %],[Opportunity_Stage].[Opportunity_Status],[Term],[Sign Date] FROM [Sheet1$];" No value given for one or more required parameters. but their are no parameters???? Checked and double checked the columns names, but to no avail. Also tried removing the special characters from the column names, but still the same exception.

• Reducing a normalized table to one value

  - by Dio

  Hello, I'm sure this has been asked but I'm not quite sure how to properly search for this question, my apologies. I have two tables, Foo and Bar. For has one row per Food, bar has many rows per food matching descriptors. Foo name id Apple 1 Orange 2 Bar id description 1 Tasty 1 Ripe 2 Sweet etc (sorry for the somewhat contrived example). I'm trying to return a query where if, for each row in Foo, Bar contains a descriptor in ('Tasty', 'Juicy') return true ex: Output Apple True Orange False I had been solving this somewhat trivially with a case when I only had one item to match select Foo.name, case bar.description when 'Tasty' then True else 'False' end from Foo left join Bar on foo.id = bar.id where bar.description = 'Tasty' But with multiple items, I keep ending up with extra rows: Output Apple True Apple False etc etc Can someone point me in the right direction on how to think about this problem or what I should be doing? Thank you.

• Poll database using jQuery/Ajax

  - by Gav

  Hi guys, I am trying to use jQuery (latest version) & ajax to poll a mysql db every x seconds, post.php does a simple search query on the table and limits to 1 row. (eg SELECT id FROM TABLE LIMIT 1) I've got some other jQuery UI (using v1.8) code that displays some modal/dialog boxes on the screen, simply put if post.php returns something from the db I need to initialise the dialog to pop up onto the screen. I've done all the popup stuff I am just having issues joining all these bits together - i've added some pseudo code of how i expect this to work. Thanks in advance var refreshId = setInterval(function(){ $.ajax({ type: "POST", url: "post.php", data: "", success: function(html){ $("#responsecontainer").html(html); } }); }, 2000 );s /* proposed pseudocode */ if (ajax is successful & returns a db row to #responsecontainer) { show jQueryUI modal (done this bit already fortunately) }

• PHP MYSQL Add up number of entries in single table and display in HTML

  - by Derek

  I have a table called activities which contains a number of activities for projects (for example 6 activities are related to one project). On a manage projects page, you can see the projects, and I have one column which needs to display the number of tasks associated with the project (in that particular row). So basically, I need a query or PHP calculation that can add up the number of tasks for the project and then display this number dynamically! I know exactly what I need, just do not know how to implement it. Any help is much appreciated! Thanks.

• Matching an IP address with an IP range?

  - by Legend

  I have a MySQL table setup as follows: +---------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------+-------------+------+-----+---------+----------------+ | ipaddress_s | varchar(15) | YES | MUL | NULL | | | ipaddress_e | varchar(16) | YES | | NULL | | +---------------+-------------+------+-----+---------+----------------+ where, ipaddress_s and ipaddress_e look something like: 4.100.159.0-4.100.159.255 Now is there a way I can actually get the row that contains a given IP address? For instance, given the IP address: "4.100.159.5", I want the above row to be returned. So I am trying for a query that looks something like this (but of course this is wrong because in the following I am considering IPs as strings): SELECT * FROM ranges WHERE ipaddress_s<"4.100.159.5" AND ipaddress_e>"4.100.159.5" Any suggestions?

• From comma separated list to individual item result set. *mysql

  - by Raziel

  I'm doing some data migration from a horribly designed database to a less horribly designed database. There is a many to many relationship that has a primary key in one table that corresponds to a comma separated list in another. FK_ID | data ------------- 1,2 | foo 3 | bar 1,3,2 | blarg Is there a way to output the FK_ID field with each comma separated element as a single line in the result set? result set FK_ID | data ------------- 1 | foo 2 | foo 3 | bar 1 | blarg 2 | blarg 3 | blarg I'm thinking this would require some sort of recursive query which I don't think mysql has. Thanks in advance.

• how to populate an entity you have extended in the Entity Framework?

  - by user169867

  I have an entity in my EDMX that I've extended with a few fields in a partial class like this: public partial class Employee { public string JobName {get;set;} } These properties are for display only. In the above example say the entity has a JobTypeID property. I wish JobName to be populated w/ the name that belongs to that JobTypeID. Is there anyway to query the employee record in EF including the value for the JobName property w/o explicity assigning each field using select()? The reason I ask is that there are a lot of fields in the Employee entity so I'd like to be able to take advantage of something like: ctx.Employees.Where(e=>e.EmployeeID==employeeID).Single() ...add somehow fill in JobName too Is this possible?

• Most efficient way for a lookup/search in a huge list (python)

  - by user229269

  Hey guys, -- I just parsed a big file and I created a list containing 42.000 strings/words. I want to query [against this list] to check if a given word/string belongs to it. So my question is: What is the most efficient way for such a lookup? A first approach is to sort the list [list.sort()] and then just use the if word in list: print 'word' -- which is really trivial and I am sure there is a better way to do it. My goal is to apply a fast lookup that finds whether a given string is in this list or not. If you have any ideas of another data structure, they are welcome. Yet, I want to avoid for now more sophisticated data-structures like Tries etc. I am interested in hearing ideas (or tricks) about fast lookups or any other python library methods that might do the search faster than the simple 'in'. Thanks in advance!

• Searching algorithmics: Parsing and processing a request

  - by James P.

  Say you were to create a search engine that can accept a query statement under the form of a String. The statement can be used to retrieve different types of objects with a given set of characteristics and possibly linked to other objects. In plain english or pseudo-code using an OOP approach, how would you go about parsing and processing statements as follows to get the series of desired objects ? get fruit with colour green get variety of apples, pears from Andy get strawberry with colour "deep red" and origin not Spain get total of sales of melons between 2010-10-10 and 2010-12-30 get last deliverydate of bananas from "Pete" and state not sold Hope the question is clear. If not I'll be more than happy to reformulate. P.S: This isn't homework ;)

• 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?

We want ANY user under Security Groups OU to have access to the application and not just the CN. Tomcat does not search OU's and it just searches CN's in our case. How do we configure our settings so we can do OU level authorization and not just CN level ? thanks Mat

• MySQL.. search using Fulltext or using Like? What is better?

  - by user156814

  I'm working on a search feature for my application, I want to search all articles in the database. As of now, I'm using a LIKE in my queries, but I want to add a "Related Articles" feature, sort of like what SO has in the sidebar (which I see as a problem if I use Like). What's better to use for MySQL searching, Fulltext or Like... or anything else I might not know about? Also, I'm using the Kohana Framework, so If anybody knows an easy way to do fulltext matching using the query builder, I'd appreciate that. Thanks.

• Search the public stream in Facebook

  - by camilo_u

  Hi, Is there any change i can search for anything in the Open Stream in Facebook? Let´s say that i want to look for "obama", this will return all of the obama mentions for a bunch of people in their streams, so far I haven't found anything like this, probably only looking in one user stream, but not the whole stuff. So, i haven't found a way to do this, but how come, sites like socialmention.com can do it? Do they query user by user streams? and how to do it without users permissions? What do you guys think? Thanks in advance! Camilo

• Apache setting mod_auth_ldap require settings per sub-directory

  - by Anthony

  I would like to set up a primary directory that has one set of LDAP-based restrictions and then have various sub-directories use other restrictions, but only have the actual LDAP search done in the base directory. For example: .htaccess per directory /Primary_Directory AuthLDAPURL "ldap://ldap1.airius.com:389/ou=People, o=Airius?uid?sub?(objectClass=*)" Require group cn=admins ../Open2All Require valid-user ../No_Admins_Allowed Require group cn!=admins So basically, the primary directory (in this example) can only be accessed by users who are in the admins group, while the first sub-directory can be accessed by anyone in the directory, and the second sub-folder can be reached by anyone who is NOT in the admin-group. But I only want to set the Require line for the sub-directories, and not re-setup the LDAP query on each sub-directory. Is this possible, even though there are clear permissions conflicts from level to level? Does the deepest .htaccess file know that the Require line refers to the LDAP search in the parent folder?

• Find overdrawn accounts in SQL

  - by mazzzzz

  Hey guys, I have a program that allows me to run queries against a large database. I have two tables that are important right now, Deposits and withdraws. Each contains a history of every user. I need to take each table, add up every deposit and withdraws (per user), then subtract the withdraws from the deposits. I then need to return every user whos result is negative (aka they withdrew more then they deposited). Is this possible in one query? Example: Deposit Table: |ID|UserName|Amount| |1 | Use1 |100.00| |2 | Use1 |50.00 | |3 | Use2 |25.00 | |4 | Use1 | 5.00 | WithDraw Table: |ID|UserName|Amount| |2 | Use2 | 5.00 | |1 | Use1 |100.00| |4 | Use1 | 5.00 | |3 | Use2 |25.00 | So then the result would output: |OverWithdrawers| | Use2 | Is this possible (I sure don't know how to do it)? Thanks for any help, Max
