    thank you, it works great! ;) this is the final version of my enum implementation: //Report Type enum implementation final class ReportType { const Total = 'total'; const SpecificCenter = 'specific_center'; const AllCenters = 'all_centers'; const Average = 'average'; // ensures...

    can a trigger know info about the process raises it?

    Hi all, in my database, I have: - a table "Visit" - a stored procedure "sp_create_visit" - a table "logs" CREATE TABLE `logs` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `operation_type` int(2) NOT NULL DEFAULT '1' COMMENT '1=no changes; 2=insert, 3=update, 4=delete', `users_id` int(11)...

    Mysql error

    if you don't use mysqli, you can run only one statement at a time. In your code, the string $title contains 2 statements (DROP and CREATE); you should separate them: //drop "title" table if exists $drop_title = "DROP TABLE IF EXISTS title;" $results = mysql_query($drop_title) or die...

    Mysql error

    oh right: you cannot run multiquery statements using mysql_query. To do that, you must use mysqli: http://php.net/manual/en/mysqli.multi-query.php however, the CREATE TABLE statements have an extra ")" and raise errors if you run them directly in MySQL --- The surest sign that intelligent...

    Automatic Empty to Null Conversion

    I also think it should be done by your application However, you can force the NULL values using before triggers. Here is an example: DELIMITER $$ CREATE TRIGGER t_insert_before_table BEFORE INSERT ON table FOR EACH ROW BEGIN IF NEW.Textfield = '' THEN NEW.Textfield=NULL...

    limit number of parameters in a stored procedure

    mmm... maybe I've done the wrong example; however the columns are not similar: they have different meanings and types (number, varchar, text, enum) Every visit can track different values so the columns for the first visit aren't the same of the column in the second visit. Now I have data for...

    limit number of parameters in a stored procedure

    it's our database design, but I describe it in a quick way; it's more complicated. Now we used the system to generate clynical studies so every questionnaire is a visit. There are several doctors that logon to the study's site and each doctor has more patients to visit. Every row is the patient...

    limit number of parameters in a stored procedure

    the engine receives an XML in input that contains the definition of a study formed by more questionnaires. The engine is used to publish a site (in php) and to create the database in which store the answers. There are several XSL trasformations that create php files and SQL scripts (to create...

    limit number of parameters in a stored procedure

    Hi all, is there a limit to the number of parameters in a stored procedure? I have an engine that generate a "CREATE PROCEDURE" script that receives in input a list of columns. I cannot find a way to pass an array parameter in MySQL, so the XSLT must create a parameter for each column: CREATE...

    Cursor for a prepared SELECT

    Hi all, how can I create a cursor for a SELECT statement previously prepared? I must do something like this: DECLARE cur CURSOR FOR SELECT * FROM <tab> WHERE Id=<id>; <tab> and <id> are parameters passed to my stored procedure. Can I prepare the SELECT statement and then assign it to the cursor...
