How do you create a TABLE in MySQL?
To create a table in MySQL you will need to use the CREATE TABLE function. This is simple enough to use, a simple example of creating a users table is below, it has a unique id (Primary Key) with a unique username and a password field (which I would recommend storing as an MD5). CREATE TABLE users (id INT( 10 ) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY , username VARCHAR( 16 ) NOT NULL , password CHAR( 32 ) NOT NULL , UNIQUE ( username ) );
How do you retrieve data stored in the database into the dropdown using PHP?
<select name="select1"> <option value="">Please Select...</option> <?php $fetchQuery = mysql_query("SELECT * FROM `table`"); while($showOutput = mysql_fetch_object($fetchQuery)){ echo "<option value="{$showOutput->value1}">{$showOutput->value2}</option>"; } ?> </select> Using the while function is very useful. If you wish to limit the amount of outputted lines, use LIMIT 10 at the end of the mysql query. Lewis.
How do you join two tables in an Access query where it returns all fields that are not in one of the tables only?
I am confused with your question, so I will do both interpretations. The query wizards may help you but you didn't say which Access you are using so we will do it in the query builder instead. ................. You have a table with 25 keys and a table with 10 foreign keys for this example. This could be a one-to-one relationship or a one-to-many in which the 'many' table just has records that match some of the keys in the 'one' table. You want to see all the 25-key table and anything in the 10-key table that matches. So 15 of the keys from 25-key will not match the 10-key table but you want to see them anyway. In the query builder, link the key fields going from the 25 table to the 10 table. Then right-click on the link and select the 2nd option "show all from 25-table and the matching records in the 10-table". Run the query. You will see everything from the 25-table. In the fields from the 10-table there will be blanks where nothing matches. .................. My second guess is you want to see the ones that don't have a matching key. If it matches you don't care about it, like when you are trying to find keys to fix so you can have integrity between the tables. You have a table with 10 keys and a table with 25 foreign keys and you need to find those extra 15 foreign keys so you can fix the data integrity. (Notice that this is the opposite of the 2 tables in example 1 - the extras are in the foreign key table. You will most often have this problem when you import data, not when you are doing data entry.) In the query builder link the tables, 25-table to 10-table. Again do the right-click on the link and select the 2nd option. Show only the fields of the 25-table down in the bottom part. Now drag the key field from the 10-table down to the grid. Un-check the box under the field name and table name. In the criteria row type "Is Null". Run the query. You will see the records from the 25-foriegn key table that need to have keys set up in the 10-key table. .................. In both cases, if you want to filter the records do it in queries and then link the filter queries instead of the tables. This is an over-simplification and I am assuming you have actual key fields set up, like an autonumber field on the 'one' side. If you have something like "blue", "red", "green" as your key field you have some real work to do.
Why use mysql instead of oracle?
Most people who select oracle over mysql are doing so for a variety of reasons, not one specific feature. Price is usually the most important factor. MySQL is free, and that's why many people choose to use it. Oracle is time-tested/proven, and that is why many people choose it.However, many corporations purchase volume licenses and so the cost of adding an new database/user to an oracle database is not as much as it would be to start your first implementation.Reasons to use oracle instead of MySQL:1.Oracle has many built in functions such as decode that make some queries easier to build.2. Oracle is a private company, and some people argue this means that they will deliver releases/fix defects/etc more regularly, since they rely on the income to survive.3. Oracle has PL/SQL, a built in language that is very powerful. You can also have java stored procedures, this is much more powerful then what MySQL offers.4. Oracle has support for sequences, MySQL does not.5. Mysql does not support table snapshots6. Oracle can be customized and tuned, much more then MySQL can.7. Oracle provides Hot Backup/Standby facility, Mysql provides this facility only for selected engines.8. Oracle provides Clustering Mechanism, where as MYSql does not.9. Oracle Provides two way replication, Mysql provides only one-way replication.10. Oracle provides DB links to connect to a remote oracle server.
