Or think like this, you happen to be a student creating a project on Oracle DB. However, now you require exporting some data into Excel for analysis purposes. The big question that arises here is that – how to extract data from Oracle database without getting any errors?
Query: How to export data from Oracle database accurately to Excel?
Answer: You can make use of Oracle SQL Developer, but for accurate results, you must choose to use a practical export tool that exports data straight into Excel.
Query: Which is the most accurate way to export data from Oracle DB?
Answer: The most accurate method is to use a certified solution, which guarantees accurate exportation without any such data loss.
Why the Need to Export Data from Oracle Database Generates?
Businessmen, students, researchers, as well as IT people usually face the requirement to export data from Oracle database for many different reasons. This could be for reporting purposes, auditing work, migration needs, or even legal investigations. Without accurate exportation, data remains locked inside Oracle, which makes it hard for such people to use it at other places.
As per Statista, Oracle happens to be one of the top three DBMS systems globally. It has a market share of almost 25 percent. This clearly suggests that users usually require getting data from Oracle databases for different purposes related to several real-world requirements.
Check Out Something That Happened in the Real World
A retail firm used to store all their transaction records inside Oracle databases on an everyday basis. At the completion of each quarter, their finance team faces the need to extract data from Oracle database into CSV for analyzing their customer purchase patterns. Without proper exportation, creating such business insights is difficult!
When Does the Need to Export Data from Oracle Database Appear?
You can find some common scenarios below making this export necessary:
- Data Backups – Users need to keep secondary copies in other formats.
- Data Migration – The need arises while shifting something from Oracle to some other system.
- Legal Investigations – For the purpose of investigations, experts need to export forensics-ready evidence, mainly to show in court cases.
- Testing and Development – Developers usually need to export sample datasets for the purpose of application testing.
- Data Analysis and Reporting – Many professionals need to move Oracle data to CSV for reporting purposes.
Exporting Data Manually!
Yeah! You can export data from Oracle DB manually, as under:
- Using Oracle SQL Developer – This is a free GUI tool for exporting views, tables, and/or queries into CSV/Excel/XML.
- Make Use of Data Pump Export (expdp) – This happens to be a command-line utility to export huge volumes of data.
- Making Use of SQL*Plus – You can write queries with a spool command to save output in a text file.
Gains You Get from Manual Ways:
- Most of these do not cost anything.
- Most of them are available with Oracle installation.
- These ways are useful in cases of small datasets.
- There is no such 3rd-party dependency.
There Are Many Aspects That Limit Manual Ways
- Such processes are limited to technical users only as they need expertise to operate such commands.
- Most such ways are pretty slow in case of complex databases or huge Oracle DB.
- There would be no such built-in advanced reporting.
- Such processes can’t guarantee you hundred percent accuracy.
- There is always a risk of incomplete exportation in case of big files.
- Such ways are quite time-costing in case of large databases.
- There is no such forensic or investigative feature available in them.
A Practical Solution Is to Use a Certified Tool
Using a certified tool is the most practical decision as it gives accurate results. You can use the 4n6 Database Forensics Tool. It is designed in such a way that you can use it to export data from Oracle database and also use it to investigate & analyze evidence accurately. This is also the best-fit solution for Oracle database forensics. Such a multi-tasker tool! Wow!
Beneficial Features:
- You can export Oracle data into CSV format with ease.
- You can preview and even search required Oracle DB records before exportation.
- The software maintains data integrity during exportation (you will not see any tampering with data).
- The tool supports forensic needs as well, which is useful in legal investigations.
Easy Steps to Export Data from Oracle Database
You can check out the following easy ways to use this tool:
- Downloading and installing the software is the first and foremost step for you to start with.
- Adding Oracle DB Files with the help of the “Add Database” option comes next.
- Previewing of Data before exportation is also possible, which ensures more accuracy.
- Clicking Export and saving the data securely in CSV format finally completes your task.
Crucial Comparison between Manual & Professional
| Factor | Manual Ways | Professional |
|---|---|---|
| Speed | Slow with large files | Fast & optimized |
| Accuracy | May corrupt data | 100% accurate |
| Usage | Needs technical skills | Simple interface |
| Forensics | Not supported | Forensics-ready |
A Few Do’s & a Few Don’ts
- DO make use of a manual technique only if you are having a small dataset.
- DO use a certified solution for accuracy.
- DO NOT depend upon command-line methods if you do not have enough technical knowhow.
- DO NOT use any manual export way for forensic use and/or legal purposes.
