If another user works with the table after you create it, SQL Server deletes it after you disconnect and after all other sessions are no longer actively using it.Im trying to migrate from Laravel 3 to Laravel 4 If no other user works with this table after you create it, the table is deleted when you disconnect. Lets look at an Oracle DECLARE LOCAL TEMPORARY TABLE example: DECLARE LOCAL TEMPORARY TABLE supplierstemp ( supplierid number (10) NOT NULL, suppliername varchar2 (50) NOT NULL, contactname varchar2 (50) ) This example would create a LOCAL TEMPORARY TABLE called supplierstemp in Oracle. If you create the global temporary table #employees, any user in the database can work with this table.
If a database session creates the local temporary table #employees, only the session can work with the table, and it is deleted when the session disconnects. Global temporary tables have two number signs (#) as the first characters of their names they are visible to any user after they are created, and they are deleted when all users referencing the table disconnect from the instance of SQL Server.įor example, if you create the table employees, the table can be used by any person who has the security permissions in the database to use it, until the table is deleted. Local temporary tables have a single number sign (#) as the first character of their names they are visible only to the current connection for the user, and they are deleted when the user disconnects from the instance of SQL Server. Then you execute your exec and the stored proc you have created in the exec should have the same named temp table viz.tmptable. The SELECT statement is executed multiple times and my results are incorrect as there are repetitions. They differ from each other in their names, their visibility, and their availability. Create the Temporary table by using CREATE TABLE and then use INSERT INTO to insert the values instead of SELECT INTO. I have a PHP loop which contains two sql queries.
#CREATE TEMP TABLE IN A FOR LOOP IN PHP CODE#
The second way to create a temporary table is to use the CREATE TABLE statement: CREATE TABLE haroproducts (productname VARCHAR (MAX), listprice DEC (10, 2) ) Code language: SQL (Structured Query Language) (sql) This statement has the same syntax as creating a regular table. I've tried many different versions of this, some using '' for the table and various things (are there differences in SQL server and MySQL commands). Create temporary tables using CREATE TABLE statement. SELECT id FROM employee where departmentid 1 Create the cursor which will hold the result set returned by the SQL Query. Firstly though I can't seem to get the Insert into temp table to work. Using a cursor within a stored procedure. I will be doing a 2 while loop statements in PHP to populate the temp table. It should create an array of 3 objects of your class and initialize them to. Investigate using foreach and while instead.

MySQL cursor is read-only, non-scrollable and asensitive. Let’s try to understand how we can use create table statements in MariaDB with the help of examples as follows. A cursor allows you to iterate a set of rows returned by a query and process each row individually. Temporary tables are similar to permanent tables, except temporary tables are stored in tempdb and are deleted automatically when they are no longer used. To handle a result set inside a stored procedure, you use a cursor.
