Oracle SQL Certification: 1Z0-051 or 1Z0-061?

Oracle SQL Certification: 1Z0-051 or 1Z0-061?

By Mary J. Nolasco 2 years ago

The initially of the Oracle 12c certification tests to go into output is 1Z0-061: Oracle Databases 12c: SQL Fundamentals. Oracle College set this examination into generation nearly simultaneously with the retirement of the significantly older test 1Z0-007: Introduction to Oracle9i SQL. However, the 11g model of the SQL Fundamentals exam, 1Z0-051, is however out there. Getting two equal examinations in output qualified prospects to a fair amount of confusion between certification candidates. In this article I will focus on the two examinations, what is distinct in between them, and how to opt for just one around the other.

Possibly will satisfy the SQL prerequisite for the “Oracle Database 11g Administrator Licensed Associate” or “Oracle PL/SQL Developer Certified Associate” tracks. The SQL necessity can also be happy by passing 1Z0-047: Oracle Databases SQL Pro. Even so, 1Z0-047 is a substantially tougher exam than both 1Z0-051 or 1Z0-061. This is an selection that need to only be regarded if you have labored with Oracle SQL extensively. This report focuses on the SQL fundamentals examinations.

The 11g and 12c SQL Fundamentals examinations are nearly equivalent in phrases of content included and prerequisites content for Oracle certifications. Oracle does not require you to use the 12c SQL Fundamentals when pursuing the 12c DBA track or the 11g exam for the DBA keep track of in that launch. Any Oracle SQL exam (together with retired types) can be utilised for any Oracle certification keep track of that has a SQL prerequisite. For case in point, the SQL exam I took over a ten years in the past was 1Z0-001: Introduction to Oracle: SQL and PL/SQL. That take a look at has been retired for many years, but could nevertheless be used for the 12c keep track of.

While the content of the two exams is incredibly related, there are a few variances. Equally 1Z0-051 and 1Z0-061 comprise forty-a person topics. Of people, thirty-6 are common to both equally exams. This usually means the assessments have about 88% commonality by subject count. The previous portion of the 11g examination (Producing Other Schema Objects) was taken out from the examination in the 12c variation. The subject areas included in that part are:

  • Build uncomplicated and complicated views
  • Retrieve facts from sights
  • Produce, sustain, and use sequences
  • Create and manage indexes
  • Create private and community synonyms

For the 1Z0-061 test, Oracle College added a new ‘Introduction’ segment with the pursuing 4 subjects:

  • Describe the functions of Oracle Database 12c
  • Explain the salient options of Oracle Cloud 12c
  • Make clear the theoretical and bodily areas of a relational databases
  • Explain Oracle server’s implementation of RDBMS and object relational databases administration technique (ORDBMS)

They also added 1 far more matter to the “Managing Tables employing DML statements” portion:

  • Truncate info

I have to say that I am very unhappy with Oracle University’s choice to set TRUNCATE (which is a DDL procedure) below a portion specially about DML statements. This is not a little something that would make feeling in a exam designed for people today who are new to SQL. I am certain that OU would be heartbroken to study of my disapproval.

The 1Z0-061 exam has 9 a lot more questions than 1Z0-051 (75 vs 66) and a marginally increased passing rating (65% vs 60%). This does not always suggest that the test is harder to move, although. The matters that have been additional are types that are most likely to have queries that are extra simple than the subjects that were being removed. OU has a specified concentrate on share of candidates that they want to pass every single test on a to start with endeavor. If they elevated the passing rating, it was due to the fact they felt the up-to-date exam experienced less difficult issues.

I have to say that choosing a person check about the other is truly a toss-up. The 11g exam is not specifically dated and all of the matters are nonetheless suitable. There could be a small bit of extensive-time period advantage in having the 12c test on your record relatively than 11g, merely because 12c will be all-around after 11g is retired. On the other hand, 11g is at this time the conventional database utilised in output environments. Quite number of firms will have moved to 12c yet. In addition, none of my employers have inquired (or cared) about the precise assessments I took to obtain my Oracle certifications. Decide the exam that will make the most sense to you and you can be self-confident that you are not making a blunder. Whichever 1 you decide on, great luck on the test.
