What kind of job can you find if you only know SQL?

Now, with the rapid development of the computer industry, many computer majors have not studied their courses well during college, or are only proficient in one or two languages. This has led to many people not knowing what they are doing. What kind of work can be done. Today I will talk to you about what jobs you can find if you only know SQL.

# Those who are good at SQL database can apply for database engineer DBA, ETL development engineer, performance optimizer, storage engineer, data warehouse expert, etc. The interviewer definitely hopes to recruit you to create more value, rather than just someone who only knows a certain kind of job.

During database work, you will also need to communicate frequently with programming developers. If you can understand the relevant programming statements, then you will be at ease at work and very relaxed.

So, as long as you still have the idea of ​​continuing to learn, try to learn as many languages ​​and tools as possible. You can choose one or two of the more popular programming languages ​​(such as Python, C, Java, PHP, etc.) Go and learn more about it, at least to the point where you can answer basic questions when others ask you. If you only want to engage in database-related majors, then you must make full use of database knowledge, and you must keep pace with the times. , I believe that if you do this and have a good interview status, you will definitely be able to get the offer you want.

The following is the experience of a friend who is doing data processing:

"Most of the projects I work on now only use SQL Server, and a few projects use Oracle. I write SQL every day. , maybe a few hundred lines, maybe a few thousand lines. In addition to writing SQL, I also need to do some statement-level optimization and daily maintenance of the database.

Of course, I have learned many languages: C#, VB , VC, and Java, but I have never done any actual projects using these languages. In my current job, I only write SQL statements. When I was looking for a job before, I first looked for VC and also found a job, but later I felt that it was not very good. I didn't go if it suited me, and then I started looking for jobs in SQL. There were still many opportunities, and the salary in SQL was a little higher than the VC job I was looking for before.

I think as long as you learn SQL well, you will definitely be able to find a job. , you will be asked to know this and that during the interview. In fact, it is not the most important. As long as you are good enough at a certain aspect, you do not need to be able to do everything.

In fact, most people who only write SQL are generally Are you writing reports? Our company has a bunch of reports to write. The logic ranges from simple ones with a few fields to complex ones with more than 100 fields. It can improve your level a lot. You may need to use the forum to write a report. There are a lot of skills mentioned in posts, but if you think about it, it is unlikely that you will get a salary increase if you continue to stay, so you really need to learn some programming languages, or develop horizontally like other databases, such as Oracle, which is now recruiting PL/SQL. There are many, or you can develop vertically and start by writing SQL and learn more about optimization, system maintenance, backup and restoration, etc."

Let me summarize. The friend above is very familiar with the SQL language. Among them He has also learned other programming languages. Although he is good in his position, there is not much room for appreciation in the future, so he suggested that he should learn some other languages. Therefore, to put it simply, it will be more difficult if you only know SQL. It is recommended that you try to learn as many languages ​​as possible.

Come on my friend, I hope my article will be helpful to you.
