  • SQL> spool off;

The subsequent CSV record can be foreign into PostgreSQL table through “Duplicate” summon:

Duplicate <table name> FROM <path to CSV file> DELIMITER “,” CSV;

When there is “Authorization denied” blunder subsequent to running this announcement, attempt to utilize “\COPY” charge.

Files

How about we get arundown of all files that have a place with table “mytable”:

  • SQL> select * from all_indexes where table_name = ‘<TABLE NAME>’;

Note, that Oracle stores all database protest names as capitalized as a matter of course unless thelower case was determined straightforwardly by encasing table name in quotes in “Make TABLE” explanation.

Also, this is the manner by which meaning of specific files can be extricated:

  • SQL> set long 1000
  • SQL> set pagesize 0
  • SQL> select DBMS_METADATA.GET_DDL(‘INDEX’,'<INDEX NAME>’) from DUAL;
  • Oracle to PostgreSQL Transformation Tools

The strategies clarified above exhibit that moving Oracle database to PostgreSQL is a perplexing procedure. Manual migration requires a great deal of work and it can likewise cause loss of information or defilement because of thehuman factor.

5 Common Career Branding Mistakes to Avoid

28 Jun , 2017  

While searching for a job, you need to do some sort of self-branding. This is just a compacted version of you as a professional and a person. But many job seekers tend to overlook this and end up failing to create a stellar brand of themselves. In case your personal career branding needs some kind of attention then you should avoid the following mistakes. Employers are very quick to catch them and reject the candidates.Therefore, you need to keep them in mind.

Here are five career branding mistakes to avoid when you are looking for job vacancies:

  1. Overselling Yourself: If you have a whole lot of certificates, degrees, and awards, you would definitely want to proudly display your trophies. These achievements are a part of who you are, but they don’t define you. The achievements you add to your career branding should be focused solely on the job title you are applying for. For example, if you are applying for a data entry job, then you don’t need a certificate in physical education in your personal branding file.
  2. Extra Self Praise: It is kind of similar to overselling, but in this what people tend to do is to boast of what they have done and how great they are. They think they are trying to show the employers that they cannot operate without you. If you do this, people would lose interest fairly quickly and your image would be hurt because of this.
  3. Abstract Statements: Speaking generally and with abstract statements is good if you are speaking about a lot of information in a very short amount of time. But when you are marketing your brand, the interviewers would like some details and hard facts. In case you have something tangible in your work, then you should use it.
  4. Being Too Focused on the Task: Generally, tasks are the best way of showing what has been done by you, but your career branding is much more than just a simple task. Your brand shouldn’t focus on just tasks, but the reason behind doing them also. In case you created a successful application, why did you do it and what was the approach. The interesting stuff that the interviewer is looking for is in the reasons for doing the task.
  5. Rigid Communication: You need to be very professional in your communication, especially when you are showing off your personal brand. This doesn’t mean that you need to describe everything like you have crammed it a night earlier. You should be as real as possible and converse with the interviewer rather than be like a tape recorder.

Career branding is a person’s statement. Whether it is just a cover letter or an elevator pitch, you need to be very careful and avoid the above mentioned mistakes at all costs.
