There are a number of similarities between the popularity with MySQL and Oracle as being high-quality RDBMS solutions. Both MySQL and Oracle come with a good number of administrative tools and programming APIs.
However, as excellent as Oracle is, it does have a couple of grating issues and they are,
- It costs a lot of money to own
- It’s got a restricting licensing policy
However, MySQL is open source with a better licensing policy than Oracle. And, it’s why organizations and businesses have determined it would be better to move their databases to MySQL from Oracle. Of course, doing this is easier said than done. It can be done manually, but there’s a lot to be done, and it’s riskier with corruption or data loss potentially occurring.
Ideally, you are going to need special software that will take care of the conversion process automatically.
Intelligent Converters – Oracle to MySQL
Intelligent Converters is a vendor, which has been in business since 2001, focuses on ways to do database conversion, migration and synchronization, and it designed the conversion tool Oracle to MySQL. This program works extremely well thanks to its direct reading and writing data without any middleware parts or libraries. It works in every version of MySQL and Oracle such as the cloud solutions.
Oracle to MySQL has a command line version that will automate and schedule the database conversion. The converter will move information from Oracle into a new database. However, it also pulls together the information in to your already established MySQL database.
This tool will filter information through SELECT queries, which means you can choose certain records and columns or alter data before it’s changed into MySQL format. Here are some examples of this particular feature:
- Filter Records: SELECT * FROM MyTable WHERE KeyColumn > 1000
- Choose and retitle individual columns: SELECT column1 As Name, column2 as Phone FROM MyTable
- Avoid NULL values: SELECT * FROM MyTable WHERE Address IS NOT NULL
There are instances where you need to change the column type in the database. The Oracle to MySQL converter has a feature known as the “custom column mapping,” which can change name, default value, type and NULL-attribute for table column along with omitting certain columns in the conversion.
If there’s no permitted remote connection from the target MySQL server, the program can export the information into a SQL script.
When this happens, the source database is then transferred to a local file that has SQL-statements to develop tables with the various directories and limitations and add data to them. After that, the database administrator can add the script file in to the MySQL server through one of the tools below:
MySQL console client
(psql) (mysql -h host -u user –p –vvf database_name < script_file)
phpMyAdmin (Keep in mind that phpMyAdmin lets users import dump files into an established MySQL database, which means a dump file does not need to have the “CREATE DATABASE” statement)
Keep in mind that phpMyAdmin lets users import dump files into an established MySQL database, which means a dump file does not need to have the “CREATE DATABASE” statement.
- Hit the right database name in the left frame.
- Hit SQL tab at the top of your screen.
- Type in the complete path for the dump file within the field “Location of the textfile” or you can hit the Browse button to find it via the directory tree.
Push the “Go” tab.
