How can I link a stored procedure to a temporary table?
I had a database created named Multi. All the attributes of table registration are copied into the stored procedure. In this you cannot insert from stored procedure. This is just creating a stored procedure and giving it something to hold.
This is the example of it.

create a fact table then
Not sure why there is a requirement saying: can't use temporary table as you are using store procedure. but that must be unreasonable.
if the RDBS takes care of that for you , the underlying mechanism is still store the 1st result set somewhere in the memory as middle step result. temporary table for you.
so just: create a temporary table, call the store procedure, insert data into that . why not
I am trying to get rows from multiple database tables in one of the database stored procedure in mysql.
Is this possible?
Please can you give me example about this.
CREATE DEFINER=`root`#`localhost` PROCEDURE `user_procedure`(IN uid_user int)

select ucgm_id from `conne`.conn_group_membership where uid=uid_user;
END
Cursors can take data from multiple tables, and you can use them in procedures.
I've created a stored procedure in Mysql and I was wondering if there is a command that I can get and store the name of the database that this stored procedure lives in?
How about DATABASE() ?

Your Question is wrong?..Your actual question is you have created a stored procedure inside the databases...not how to retrieve the procedure inside the database?
Ans: To know the created procedure:
mysql:\> show procedure status; //to know the procedure name..sam4 function show function staus;
mysql:\> show use create procedure emptab.test1 //emptab is database name,test1 is the procedure..
I have a MySQL stored procedure that uses a temporary table. Assume that my table name is 'temp' and I use it to store some middle data. It will create at the beginning of procedure, and will drop at the end.
CREATE PROCEDURE p()
BEGIN
CREATE TEMPORARY TABLE \`temp\`(...);
INSERT INTO \`temp\` VALUES(...);
DROP TEMPORARY TABLE \`temp\`;
END;
The problem is that this stored procedure may be used by different users concurrently, so I want to know if this can cause any problems (i.e. any conflict in inserted data in temp table). In other word is temp table a shared resource within different calls to the same SP?
No, a temp table is limited to the scope of your database connection. You can use the temp table in subsequent calls to the procedure during the same database connection, but other connections cannot access it. They can create a table by the same name, but each temp table will be independent. Temp tables go away when you close your connection.
Temporary table is visible only for current session.
So if you have several simultaneuous sessions - each one will have its own independent temporary table with the same name.
