Best SQL Certifications

3. Microsoft Azure Database Administrator Associate (DP-300) — best for SQL Server shops

Microsoft retired its classic MCSA SQL Server exams years ago, so the current Microsoft credential for SQL professionals is DP-300, which covers administering SQL Server and Azure SQL relational databases. It is active as of August 2026 with no retirement announced.

• Cost: $165 USD, priced by the country in which the exam is proctored — the cheapest ticket on this list.
• Renewal: the certification is valid for one year, but renewal is free via an online, unproctored assessment on Microsoft Learn, available from six months before expiry. That is a genuinely different regime from Oracle, which offers no free online renewal path for its cloud certs.
• Format: Microsoft's standard scaled passing score of 700/1000 applies; question counts vary, so check the official page.

Choosing between Microsoft and Oracle here is mostly a question of estate, not quality: DP-300 assumes you administer Microsoft databases; 1Z0-071 assumes you query Oracle ones. If you are a data analyst who simply needs to prove SQL fluency, 1Z0-071 tests the language more directly; if you run SQL Server in production, DP-300 speaks your employer's dialect. Microsoft's older SQL Server exams — such as Querying Microsoft SQL Server 2012/2014 (70-461) — still circulate as study material and remain a decent syllabus for T-SQL fundamentals, but they are legacy exams, not credentials to plan a 2026 CV around.

4. EDB PostgreSQL certifications — best available option for Postgres, with caveats

PostgreSQL has no official certification at all: the PostgreSQL Global Development Group issues nothing. The best-known vendor credential comes from EDB (EnterpriseDB), which offers Associate and Professional levels tagged to Postgres versions. Secondary sources describe the Professional exam as roughly 60 multiple-choice questions in 90 minutes with a 70% pass mark, about $200 USD, valid for two years — but confirm all of that on EDB's own certification page before booking, as those figures come from a single summary rather than EDB directly.

Because the ecosystem is fragmented, a Postgres-heavy candidate often gets more mileage from an Oracle or Microsoft SQL credential plus demonstrable Postgres work. The whole landscape — EDB, third-party options and how employers read them — is untangled in PostgreSQL Certification Options Explained.

Side-by-side comparison

A decision framework: match the cert to your situation

• Data analyst with no strong vendor loyalty: take 1Z0-071. It is the most language-centred exam, has no prerequisites, and never expires — one payment, permanent credential.
• Working in a Microsoft shop, or targeting one: DP-300. It is the cheapest, maps to the platform you will actually touch, and its free annual renewal keeps it current without repeat fees.
• Web, SaaS or open-source environment: the MySQL track, starting from 1Z0-908 if administration is part of your job.
• PostgreSQL specialist: consider EDB, but weigh it against simply building public proof of Postgres work — the credential's recognition is narrower than the other three.
• Already certified and wondering what it changes: which roles a SQL credential opens, and how analysts progress towards DBA and data-engineering work, is mapped in the SQL Certification Career Path; what those roles pay is a separate question covered in the SQL Certification Salary Guide.

Common mistakes when picking a SQL certification

• Assuming SQL certs expire like cloud certs. Oracle's database and MySQL credentials never expire; its OCI cloud credentials lapse after 24 months. Confusing the two leads people to skip a permanent credential for fear of a renewal treadmill that does not exist.
• Buying the exam before checking dialect fit. Sitting an Oracle SQL exam when your entire career runs on T-SQL is not fatal, but it adds friction — you will study syntax you may never use.
• Chasing a "PostgreSQL official cert" that does not exist. Budget your study time around that reality rather than waiting for one.
• Letting a voucher lapse. Oracle exam purchases must typically be scheduled within six months — buy the attempt only when your preparation has a date attached.
• Memorising practice answers. Practice questions are study aids for testing your understanding of exam objectives; the value is in analysing which topic areas you miss and drilling those, not in recognising question wording.

Which SQL certification should you actually book?

For most readers weighing this decision in 2026, the honest ranking is: 1Z0-071 for language-first candidates, DP-300 for Microsoft estates, MySQL 1Z0-908 for open-source stacks, and EDB only for committed Postgres specialists. No option is universally best — the engine your target employers run should settle it. Whichever exam you choose, benchmark yourself before booking: work through free sample questions for your exam, then use a full-length timed practice-test simulation to confirm you clear the passing threshold comfortably rather than marginally.
