In order to meet the demands of the development market Netmake comes, yearly, releasing new versions of Scriptcase. Acting strongly in Sectors Public and Private Sectors, today Netmake has a solid customer base, tact in Brazil and abroad. Thereafter, many companies have adopted the Scriptcase as a solution for creating systems for web, due to high productivity and ease of resources. With a vision of the future launched in 2001, the development tool Scriptcase. NetMake main focus is on creating tools for the web development environment. NetMake is a Brazilian company, founded over 10 years ago, having its headquarters located in Olinda - Pernambuco, one of the leading technology centers in Brazil. The development environment and the systems generated can be used with the main Browsers Market such as Firefox, Chrome, Internet Explorer, Opera. The development environment and the systems generated can be used with all major operating systems market such as: Windows, Linux, FreeBSD, Unix, Iseries, MAC. Developers have used the Scriptcase for creating various types of systems such as ERPs, among others. Supports relational database widely used in the market such as Oracle, DB2, SQL Server, MySQL, PostgreSQL, Sybase, MS Access, among others. DB 2 ® Scriptcase is a complete environment for rapid web application development based in a database. Interoperability Allows access to different databases in a single system, thus bringing greater ease and flexibility of the systems generated. Decentralized Development All development is done through the browser, allowing access to the development team from any location via the Internet / Intranet. Development Patterning All development is done using patterns throughout the team, making so much faster and easier for both corrective and evolutionary maintenance of systems developed. Multiplatform Scriptcase can be used in different operating systems like Linux, Windows, MAC and others. You should wlays check out the current restrictions for MySQL 5.5.Cost Reduction Using Scriptcase can reduce programming time significantly compared to conventional development. I would strongly recommend not calling any stored procedures from a Trigger, even if MySQL allows it. I explained other nasty aspects of Triggers in an earlier post. Particular - any SQL statements in the trigger should be supported by Trigger body needs to be as lightweight as possible and - in The lesson here is this: since the trigger code will execute onceįor every row affected by a DML statement, the trigger can easilyīecome the most significant factor in DML performance. The concluding point from that section states the following: Therefore avoid placing any expensive SQL statements or proceduralĪn expanded explanation of trigger overhead is given on pages 529-531. Triggers execute FOR EACH ROW - the overhead can rapidly accumulateįor statements that process large numbers of rows. Will depend upon the nature of the trigger, but - as all MySQL To the DML statement to which they apply. It is important to remember that, by necessity, triggers add overhead In fact, According to MySQL Stored Procedure Programming, page 256 under the head "Trigger Overhead" says the following: Such would be the case if triggers were manipulating tables with INSERTs and UPDATEs being stagnated to perform heavy duty MVCC inside each call to a trigger.ĭon't forget that Triggers require overhead. Even if all underlying tables are InnoDB, you will experience a proportional volume of shared row locks and annoying intermittency from exclusive row locks. Their actions are virtually hard to roll back. Triggers are, by nature, stored procedures. There is great reason why you should never call stored procedures from within triggers. I've combed through the mysql documentation and found some information on restrictions of triggers but found it to be fairly convoluted. DROP TRIGGER IF EXISTS `usergroups_comments_insert`ĬREATE TRIGGER `usergroups_comments_insert` AFTER INSERT ON `usergroups_comment`īut for some reason every time I do mysql throws an error at me that's less than helpful stating that there's a syntax error on line 4. What I'd like to be able to do is set up a trigger from usergroup_comments that works like this. WHERE dm.`status` NOT IN (200, 201, 202, 203, 204, 205)įYI I've greatly simplified the stored procedure but I do know it works without any issues. LEFT JOIN mediagallery AS dm ON ugm.mid = dm.`id` LEFT JOIN usergroup_comments AS ugm ON ugm.`gid` = ug.`id` DROP PROCEDURE IF EXISTS `sp-set_comment_count` ĬREATE PROCEDURE `sp_set-comment_count` (IN _id INT) I have created a stored procedure in mysql using the following syntax.
