How to create a database for unknown kinds of data? Posted: 21 Apr 2013 04:54 PM PDT I am in the process of designing a database for a new PHP/MySql-based application. My problem is that I do not and cannot represent what should be saved in the database because it is unlimited and changing. Here is the problem example: The application will be a shopping website that has many kind of products all of them have some shared attributes such as title and price but some kinds have specific details such as expiry date some have isbn some non. This is just an example but I really have many kinds with many different attributes. I can create a table for each kinds, but what I have is not all the available kinds, many kinds of items are unknown at this time. Is their a way to accommodate this problem without over head in the user's side?

Misunderstanding statement in MySQL documentation Posted: 21 Apr 2013 02:39 PM PDT I can't understand this statement in Optimizing Data Size: Declare columns with identical information in different tables with identical data types, to speed up joins based on the corresponding columns. Can anyone describe this statement with example?

How to fix filestream SQL database Posted: 21 Apr 2013 04:58 PM PDT I have SQL Server 2008 R2 FileStream enabled Database, when I try to access any value that stored in the filestream I get the following error : Msg 233, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) Also the following error thrown in the SQL ERRORLOG file : SqlDumpExceptionHandler: Process 51 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process. I read about that exception and Microsoft has KB for it (KB972936), but it also didn't worked after I installed its hotfix. If I SELECT the count of the records in that table using : SELECT COUNT(1) FROM [Table_Name] I get a correct result. Here is some details for the database files and filegroups : The database have 2 files the "Row Data" file and the "Log" file where it should also contains the "Filestream Data" item. The database has the following filegroups : Rows : PRIMARY with 1 File Filestream : [MyFileName] with 0 Files ! Here is a snapshots for the DB properties page And here is the full SQL ERRORLOG file. Its my first question here, Any help please ..

Creating an admin user in Oracle Posted: 21 Apr 2013 01:27 PM PDT How can I create a "root" (like on MySQL) in Oracle? I installed Oracle database on my system, for homework, for school (faculty) but it didn't give me the option to make a root user. Well at least I don't think so. It asked me on preparation for install to create a password but when I tried connecting with the id and password it failed. (So that is why I presume it did not make a root user) Connected on the databse with connect /as sysdba but don't know how to create a user with admin privileges. Tried create user "user" identified by "password" with grant option; (error) create user "user" identified by "password"; (succes) grant all on "user" with grant option; (error) I want to have all privileges on all tables, etc.

how to set a column to fetch the date now? Posted: 21 Apr 2013 09:37 AM PDT hi i have a sample table named datenow and used the following to create my table on flamerobin to have a column that gets the date today automatically when an entry is added. CREATE TABLE "DATENOW" ( ID Char(8) NOT NULL, "Start_Date" Char(10), "Client_Name" Varchar(30), BALANCE Integer, select cast('Now' as date) from rdb$database CONSTRAINT PK_datenow PRIMARY KEY (ID) ); GRANT DELETE, INSERT, REFERENCES, SELECT, UPDATE ON "datenow" TO SYSDBA WITH GRANT OPTION; also tried inserting these sql statement select date 'Now' from rdb$database select time 'now' from rdb$database select timestamp 'NOW' from rdb$database but i cannot generate a table and cant determine where will i put the sql statement or what to do in order to have a column that gets the date today automat

What is a partitioned view? Posted: 21 Apr 2013 06:58 AM PDT What is a partitioned view? I googled but could not get a satisfactory result.

How should I store multiple relationships (many posts to many categories)? Posted: 21 Apr 2013 08:23 AM PDT I have posts stored in a posts table and I want each post to have multiple categories, what is the most efficient way to store the categories and their relationships ? I thought of it this way first: Categories Table: +------------+---------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+---------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | name | varchar(32) | NO | | NULL | | | parent | int(11) | NO | | NULL | | +------------+---------------+------+-----+---------+----------------+ Relationships Table: +------------+---------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+---------------+------+-----+---------+----------------+ | post_id | int(11) | NO | | NULL | | | cat_id | int(11) | NO | | NULL | | | order | int(11) | NO | | NULL | | +------------+---------------+------+-----+---------+----------------+ Using this structure I will have lots of rows inside the relationships table, for example if a post has 4 categories I will have 4 rows only for this post, of course I won't have that much categories related to the post but I want to implement the same structure for tags too. Am I doing it right ? is there a better structure to use ?

Postgres: Given some parent id's how can I SELECT X child records for each? Posted: 21 Apr 2013 05:07 AM PDT In Postgres, if I have : Parent Table id, name 1, Parent1 2, Parent2 ..... 5, Parent5 Child Table id, parent_id, name 1, 1, Child1 2, 1, Child2 ..... 6, 2, Child6 ..... 25, 5, Child25 so 5 children for each parent, how do I get, say, the first 3 children for parent id 1,3,4 in one query?

Is there a way to stop MySQL Replication on the master? Posted: 21 Apr 2013 03:01 PM PDT I want the master to stop replicating data to the slave. I know I can do that on the slave with STOP SLAVE;, but I wonder if there is a way to do it in the master. One possible solution might be to change the server_id to 0, but in this case I'll have to restart mysql in the master for changes to take effect. What I'm looking for is a statement like STOP MASTER;.

Is there a way to recover this database (MySQL) Posted: 21 Apr 2013 09:51 AM PDT I did a "cold" (db offline, all filesystem files) backup of a MySQL db. I wrote the backup to an ISO image. Unfortunately Joliet filenames are not default. I didn't realize that until attempting to restore the backup and notice that the entire set of files are in DOS 8.3 format. Many of the MySQL filesystem files are not 8.3. Anyone have tips or information on whether this is a lost cause? If it's not a lost cause for restoring, are there some tips directions that can be offered? Much appreciated.

SSIS Data Flow Task Slows Down Posted: 21 Apr 2013 08:33 AM PDT I am trying to transfer data from one table to another in the same database using SSIS. It seems to go fine (I can see the record count going up) until it gets to about 30 million records, then it starts pausing. It will resume again but there are really long pauses in between. I've made sure to set my initial database size large enough so that it won't have to grow during the process. I am using OLE DB as a source and destination with fast load. Any ideas why it runs great and then slows right down?

How do I stop a query from running if the row is locked? Posted: 21 Apr 2013 02:07 PM PDT I have a section of code that locks the database, updates it and then confirms. This is all working fine, if another user attempts to update the same row they cannot and their changes are discarded. My problem is that there is a variable that is updated each time the query is run, this increases whether the query was successful or not. So what I need is the query NOT to run in the first place if the row is locked, how do I do this? James

Is there a generic SQL-92 ODBC 64-bit Mac driver for Python? Posted: 21 Apr 2013 02:13 AM PDT I have a 4D SQL database which implements SQL-92. 4D's ODBC driver does not work on my system because it is compiled for 32 bit (and I am on 64 bit) and it is closed source. I wonder if there is some generic 'SQL 92' driver (or ODBC driver) that I could use to make this connection?

SQL Server best practice for tempdb log file Posted: 21 Apr 2013 09:27 PM PDT I have read many blogs here and there about how to configure tempdb data files but i didnt found any information regarding the tempdb log file. Here's the strategy that i'm presently using with my tempdb: I have used the recommendations of Paul Randal on how to split my tempdb data files I have set the size of my tempdb data files to their maximum and disabled autogrowth. For example, i have 100gb of free disk space and set the size of my 8 tempdb data files to 10gb each. This prevent fragmentation on the disk as recommended by Brent Ozar and also i have 20gb free for my log file. But like i said, nobody is talking about the tempdb log file. What should i do with it? On my setup, this file is at the same place as the tempdb data files. What is the size and the autogrowth value that i should use with the tempdb log file?

Exporting and importing a database Posted: 21 Apr 2013 04:25 AM PDT I have setup an Oracle 11g Database and have a question about exporting and importing a database. I am using Enterprise Manager and have browsed to the following: Data Movement->Export to Export Files. Down the bottom of the screen, I need to supply Host Credentials. When trying to use the username SYS, I see that the error message says to logout and login using a different role. What role should I use? Should I create a specific role for this task, and if so, what priviledges should the role have?

Linux 32b MySQL periodically crashing with signal 11 and OOM errors Posted: 21 Apr 2013 09:03 PM PDT I have a MySQL DB with mostly InnoDB tables that I'm fairly certain isn't tuned properly based on what's happening, but I don't have enough know how to pinpoint what to change.

Second time query execution using different constants makes faster? Posted: 21 Apr 2013 02:03 AM PDT Can someone explain or direct me how execution on indexes happen with different constants at intervals in Mysql. I notice only for the first execution on the table it takes time, after that with different constants it executes the query very quickly. I would like to know how to execute the query in such a way that it should take same amount of time every time it executes with different constants, is there a way to set some parameter off / on? Query executed time : 9 mins. mysql> EXPLAIN SELECT chargetype, COUNT(br.`id`), SUM(br.`charge`) FROM billingreport AS br WHERE br.`addeddate` BETWEEN '2013-02-01 00:00:00' AND '2013-02-28 23:59:59' AND br.`status` = 'success' AND br.`idvendor` = 10 GROUP BY chargetype \G *************************** 1. row *************************** id: 1 select_type: SIMPLE table: br type: index_merge possible_keys: NewIndex3,NewIndex6,idx_br_status key: NewIndex3,idx_br_status key_len: 4,1 ref: NULL rows: 2887152 Extra: Using intersect(NewIndex3,idx_br_status); Using where; Using temporary; Using filesort 1 row in set (0.00 sec) Query executed time : 18 Secs. mysql> EXPLAIN SELECT chargetype, COUNT(br.`id`), SUM(br.`charge`) FROM billingreport AS br WHERE br.`addeddate` BETWEEN '2013-01-01 00:00:00' AND '2013-01-31 23:59:59' AND br.`status` = 'success' AND br.`idvendor` = 10 GROUP BY chargetype \G *************************** 1. row *************************** id: 1 select_type: SIMPLE table: br type: index_merge possible_keys: NewIndex3,NewIndex6,idx_br_status key: NewIndex3,idx_br_status key_len: 4,1 ref: NULL rows: 3004089 Extra: Using intersect(NewIndex3,idx_br_status); Using where; Using temporary; Using filesort 1 row in set (0.01 sec)

MySQL General log not working on Mac OS X Posted: 21 Apr 2013 01:03 PM PDT I want to log all queries to the database running on my MacBook Pro (Mac OS X 10.8.1). I created a file /etc/my.cnf with the following content: [mysqld] general_log=1 general_log_file=/Users/wdb/mysql.log I restarted MySQL and tried some queries on the mysql command line, but nothing gets logged. The file is not getting created. I also created the file myself afterwards to test with touch, but the file remains empty. When I check, MySQL did read my settings: mysql> show variables like '%general_log%'; +------------------+----------------------+ | Variable_name | Value | +------------------+----------------------+ | general_log | ON | | general_log_file | /Users/wdb/mysql.log | +------------------+----------------------+ 2 rows in set (0.01 sec) Is there anything else I need to do? I suppose any query I type on the command line should get logged, right? I am using MySQL 5.5.24

postgis problem with shortest distance calculation Posted: 21 Apr 2013 08:03 AM PDT while working with POSTGIS pgrouting, for calculateing the distance between two roads(lines) i got the shortest_path function. But the logic is based on Start_point(Start_id) and end_point(end_id) but in my data the linestring contains so many internal points like ('linestring(1 1,2 2,3 3,4 4,5 5)' just for example..) it is taking start point (1 1) endpoint(5 5) if other line starting with (5 5) it is showing as route...like ('linestring(5 5,6 6)') But line which crossing the point inside the linestring like(2 2,3 3,4 4) which is not telling as connected.. example table roads: id name way 1 A linestring(1 1,2 2,3 3,4 4,5 5) 2 B linestring(5 5,6 6) 3 c linestring(2 1,2 2,2 3) if i am applying shortest_path function from point(1 1) to (6 6) its showing the way but for (1 1) to (2 3) it is not showing anything...but there is a route for this (1 1,2 2,2 3) can anyone please help me out for finding the solution.. Regards Deepak M
