  • How to convert a MSSQL database (including procedures, functions and triggers) to a firebird databas

    - by user193655
    I am considering migrating to Firebird. To have a "quick start" approach I downloaded the trial of a conversion tool (DBConvert) and tried it. I just picked up a random tool, this tool doesn't convert procedures, functions and triggers (I don't think it is a limit of the trial since there is not an explicit reference to sp, sf and triggers in the link above). Anyway by trying that tool I had the message: "The DB cannot be converted succesfully because some FK names are too long." This is because in some tables I have FK whose description is 32 chars. Is this a real firebird limit or it is possible to overcome it somehow (of course renaming the FK is an extreme option because it is extra work)? Anyway how to convert a MS SQL DB fully to FIREBIRD? Is there a valid tool? Did someone succed in a conversion of non trivial databases?

  • Connection to DB2 in Python

    - by Mestika
    Hi, I'm trying to create a database connection in a python script to my DB2 database. When the connection is done I've to run some different SQL statements. I googled the problem and has read the ibm_db API (http://code.google.com/p/ibm-db/wiki/APIs) but just can't seem to get it right. Here is what I got so far: import sys import getopt import timeit import multiprocessing import random import os import re import ibm_db import time from string import maketrans query_str = None conn = ibm_db.pconnect("dsn=write","usrname","secret") query_stmt = ibm_db.prepare(conn, query_str) ibm_db.execute(query_stmt, "SELECT COUNT(*) FROM accounts") result = ibm_db.fetch_assoc() print result status = ibm_db.close(conn) but I get an error. I really tried everything (or, not everything but pretty damn close) and I can't get it to work. I just need to make a automatic test python script that can test different queries with different indexes and so on and for that I need to create and remove indexes a long the way. Hope someone has a solutions or maybe knows about some example codes out there I can download and study. Thanks Mestika

  • Fastest way to compress a database or .bak file and transfer it

    - by Nai
    As per the question title. I wonder if there are special programmes or commands that makes zipping up a .bak file and transferring it super quick. I read abour xp_cmdshell here but I'm not sure about the speed. My .bak file is about 12 gigs at the moment. Related to this is the possibility of using Red Gate's SQL Data Compare to just transfer the differential data across the network pipeline but I have never used SQL Data Compare before and I'm not sure how it goes about doing INSERTS on tables with Primary Keys and such. Also, not sure about the speed. Does anyone have any experience with this programme or similar programmes? Cheers!

  • JSON documents and SQL database tables

    - by Sharmi
    Do JSON documents in RavenDB cost more than the SQL Server tables in terms of the storage and query costs. And also for centralized access, which one is better? What are the disadvantages of NON-SQL databases like RavenDB,CouchDB,MongoDB, etc... ? I can get that some of these are open source and support more datatypes like enums,objects,etc. but otherwise i don't see any big advantage? Currently there is a problem of storing huge amount of logs from various locations. I am planning to suggest these to my manager so just need a clear idea.

  • looping through variable post vars and adding them to the database

    - by Neil Hickman
    I have been given the task of devising a custom forms manager that has a mysql backend. The problem I have now encountered after setting up all the front end, is how to process a form that is dynamic. For E.G Form one could contain 6 fields all with different name attributes in the input tag. Form two could contain 20 fields all with different name attributes in the input tag. How would i process the forms without using up oodles of resource.

  • MySQL forgot about automatically creating an index for a foreign key?

    - by bobo
    After running the following SQL statements, you will see that, MySQL has automatically created the non-unique index question_tag_tag_id_tag_id on the tag_id column for me after the first ALTER TABLE statement has run. But after the second ALTER TABLE statement has run, I think MySQL should also automatically create another non-unique index question_tag_question_id_question_id on the question_id column for me. But as you can see from the SHOW INDEXES statement output, it's not there. Why does MySQL forget about the second ALTER TABLE statement? By the way, since I have already created a unique index question_id_tag_id_idx used by both question_id and tag_id columns. Is creating a separate index for each of them redundant? mysql> DROP DATABASE mydatabase; Query OK, 1 row affected (0.00 sec) mysql> CREATE DATABASE mydatabase; Query OK, 1 row affected (0.00 sec) mysql> USE mydatabase; Database changed mysql> CREATE TABLE question (id BIGINT AUTO_INCREMENT, html TEXT, PRIMARY KEY(id)) ENGINE = INNODB; Query OK, 0 rows affected (0.05 sec) mysql> CREATE TABLE tag (id BIGINT AUTO_INCREMENT, name VARCHAR(10) NOT NULL, UNIQUE INDEX name_idx (name), PRIMARY KEY(id)) ENGINE = INNODB; Query OK, 0 rows affected (0.05 sec) mysql> CREATE TABLE question_tag (question_id BIGINT, tag_id BIGINT, UNIQUE INDEX question_id_tag_id_idx (question_id, tag_id), PRIMARY KEY(question_id, tag_id)) ENGINE = INNODB; Query OK, 0 rows affected (0.00 sec) mysql> ALTER TABLE question_tag ADD CONSTRAINT question_tag_tag_id_tag_id FOREIGN KEY (tag_id) REFERENCES tag(id); Query OK, 0 rows affected (0.10 sec) Records: 0 Duplicates: 0 Warnings: 0 mysql> ALTER TABLE question_tag ADD CONSTRAINT question_tag_question_id_question_id FOREIGN KEY (question_id) REFERENCES question(id); Query OK, 0 rows affected (0.13 sec) Records: 0 Duplicates: 0 Warnings: 0 mysql> SHOW INDEXES FROM question_tag; +--------------+------------+----------------------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ | Table | Non_unique | Key_name | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | +--------------+------------+----------------------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ | question_tag | 0 | PRIMARY | 1 | question_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 0 | PRIMARY | 2 | tag_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 0 | question_id_tag_id_idx | 1 | question_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 0 | question_id_tag_id_idx | 2 | tag_id | A | 0 | NULL | NULL | | BTREE | | | question_tag | 1 | question_tag_tag_id_tag_id | 1 | tag_id | A | 0 | NULL | NULL | | BTREE | | +--------------+------------+----------------------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+ 5 rows in set (0.01 sec) mysql>

  • Return database messages on successful SQL execution when using ADO

    - by peacedog
    I'm working on a legacy VB6 app here at work, and it has been a long time since I've looked at VB6 or ADO. One thing the app does is to executes SQL Tasks and then to output the success/failure into an XML file. If there is an error it inserts the text the task node. What I have been asked to do is try and do the same with the other mundane messages that result from succesfully executed tasks, like (323 row(s) affected). There is no command object being used, it's just an ADODB.Connection object. Here is the gist of the code: Dim sqlStatement As String Set sqlStatement = /* sql for task */ Dim sqlConn As ADODB.Connection Set sqlConn = /* connection magic */ sqlConn.Execute sqlStatement, , adExecuteNoRecords What is the best way for me to capture the non-error messages so I can output them? Or is it even possible?

  • Insert string from database into an aspx and have databinding expressions within that text evaluated

    - by Christopher Edwards
    Well, as you can see I want something quick-and-dirty! How can I get a string from a db that has aspx databinding syntax in it and have the databinding expressions evaluated? So I have text such as this stored in the DB:- Hello <%=User.Name %> I haven't seen you since <%=User.LastVisit %> And I want it to be inserted here say:- ... <body> <form id="form1" runat="server"> <div> <asp:FormView ID="FormView1" DataSourceID="DataSource1" runat="server"> <ItemTemplate> <-- insert stuff here! --> ... But with the databinding expressions evaluated. I'd rather not build a full parsing, templating and evaluation engine...

  • How to group a database write and spreadsheet write in single "transaction"

    - by WhyGeeEx
    I have a Java program that writes results to both a DB (SQL Server) and a spreadsheet (POI), and it would be best if neither is written to if there's an error with either. It would be a lot worse if the spreadsheet was produced and then an error happened while saving to the DB, so I'm doing the DB-write first. Even so, I'm wondering if someone knows of a way to guarantee they both succeed or fail as a unit. Thanks!

  • Tree data in MySql database table

    - by Robert Koritnik
    I have a table that uses Adjacency list model for hierarchy storage. My most relevant columns in this table are therefore: ItemId // is auto_increment ParentId Level ParentTrail // in the form of "parentId/../parentId/itemId" then I created a before insert tigger, that populates columns Level and ParentTrail. Since the last column also includes current item's ID I had to use a trick in my trigger because auto_increment columns are not available in the before insert trigger. So I get that value from the information_schema.tables table. All works fine, until I try to write an update trigger, that would update my item and its descendants when the item changes its parent (ParentId has changed). But I can't make an update on my table inside the update trigger. All I can do is to change current record's values but not other's. I could use a separate table for hierarchy data, but that would mean that I would also have to create a view that would combine these two tables (1:1 relation) and I would like to avoid this is at all possible. Is there a way to have all these in the same table so that these fields (Level and ParetTrail) set/update themselves automagically using triggers?

  • Copying a massive databse for local ruby on rails development?

    - by tesmar
    Hi guys, There is a massive database (GB) that I am working with now and all of the previous development has been done on a slicehost slice. I am trying to get ready for more developers to come in and work so I need each person to be able to setup his own machine for development, which means potentially copying this database. Selecting only the first X rows in each table to cut size could be problematic for data consistency. Is there any way around this, or is a 1 hour download for each developer going to be necessary? And beyond that, what if I need to copy the production DB down for dev purposes in the future? Sincerely, Tyler

  • Return only the new database items since last check in Rails

    - by Smith
    I'm fairly new to Ruby, and currently trying to implement an AJAX style commenting system. When the user views a topic, all the current comments on that topic will be displayed. The user can post a comment on the page of a topic and it should automatically display without having to refresh the page, along with any new comments that have been posted since the last comment currently displayed to the user. The comments should also automatically refresh at a specified frequency. I currently have the following code: views/idea/view.html.erb <%= periodically_call_remote(:update => "div_chat", :frequency => 1, :position => "top", :url => {:controller => "comment", :action => :test_view, :idea_id => @idea.id } ) %> <div id="div_chat"> </div> views/comment/test_view.html.erb <% @comments.each do |c| %><div id="comment"> <%= c.comment %> </div> <% end %> controllers/comment_controller.rb class CommentController < ApplicationController before_filter :start_defs def add_comment @comment = Comment.new params[:comment] if @comment.save flash[:notice] = "Successfully commented." else flash[:notice] = "UnSuccessfully commented." end end def test_render @comments = Comment.find_all_by_idea_id(params[:idea_id], :order => "created_at DESC", :conditions => ["created_at > ?", @latest_time] ) @latest = Comment.find(:first, :order => "created_at DESC") @latest_time = @latest.created_at end def start_defs @latest = Comment.find(:first, :order => "created_at ASC") @latest_time = @latest.created_at end end The problem is that every time periodically_call_remote makes a call, it returns the entire list of comments for that topic. From what I can tell, the @latest_time gets constantly reset to the earliest created_at, rather than staying updated to the latest created_at after the comments have been retrieved. I'm also not sure how I should directly refresh the comments when a comment is posted. Is it possible to force a call to periodically_call_remote on a successful save?

  • What databse uses these specific type of .dat and .idx files?

    - by Cape Cod Gunny
    I'm trying to figure out what type of database uses these specific .dat and .idx files. When I view the .dat files using a binary file reader I see Record Schema followed by somewhat decipherable data names. A little further down I see Key Schema whch apears to be a comma separated list of clear text references. Each .dat file has a matching .idx file. Each .dat file contains the phrase "Record Schema" and "Key Schema" as described above. How would I convert these files so I can use them in an SQL database?

  • What is an elegant way to set up a leiningen project that requires different dependencies based on the build platform?

    - by Savanni D'Gerinel
    In order to do some multi-platform GUI development, I have just switched from GTK + Clojure (because it looks like the Java bindings for GTK never got ported to Windows) to SWT + Clojure. So far, so good in that I have gotten an uberjar built for Linux. The catch, though, is that I want to build an uberjar for Windows and I am trying to figure out a clean way to manage the project.clj file. At first, I thought I would set the classpath to point to the SWT libraries and then build the uberjar. This would require that I set a classpath to the SWT libraries before running the jar, but I would likely need a launcher script, anyway. However, leiningen seems to ignore the classpath in this instance because it always reports that Currently, project.clj looks like this for me: (defproject alyra.mana-punk/character "1.0.0-SNAPSHOT" :description "FIXME: write" :dependencies [[org.clojure/clojure "1.2.0"] [org.clojure/clojure-contrib "1.2.0"] [org.eclipse/swt-gtk-linux-x86 "3.5.2"]] :main alyra.mana-punk.character.core) The relevant line is the org.eclipse/swt-gtk-linux-x86 line. If I want to make an uberjar for Windows, I have to depend on org.eclipse/swt-win32-win32-x86, and another one for x86-64, and so on and so forth. My current solution is to simply create a separate branch for each build environment with a different project.clj. This seems kinda like using a semi to deliver a single gallon of milk, but I am using bazaar for version control, so branching and repeated integrations are easy. Maybe the better way is to have a project.linux.clj, project.win32.clj, etc, but I do not see any way to tell leiningen which project descriptor to use. What are other (preferably more elegant) ways to set up such an environment?

  • Building an application that includes a DB, and need recommendations

    - by Rubys
    I'm going to build a little system for personal use, and I want it to save data to a database. The language is going to be C#, and so I'd like to use this opportunity to get my head around LINQ to SQL. I have some DB experience and I know my SQL, but it was all in school using Access, which is giving me trouble, and so I'd like to use another DB, something that is small in size, easy to install, and should work with LINQ to SQL. The problem is: I don't know any except Access, and am looking for recommendations. To sum it up: I need a lightweight, easy to install, linq-to-sql supporting database for a small system on a home computer, any recommendations?
