MySQL 8.4.10Captured

See how SQL becomes a real data flow

Replay a MySQL 8.4.10 execution plan and the row sets from a deterministic fixture in one synchronized view.

Open workbench
Order Search Execution Workbench showing SQL, Execution Plan, Data Lens, and Evidence together
Featured Lab Order Search Execution

Compare how the same SQL produces a full scan and a composite-index access path, grounded in actual rows.

Workbench

Four synchronized surfaces

  1. SQL

    The active clause and predicate

  2. Execution Plan

    The active operator, access type, selected key, rows, and cost

  3. Data Lens

    Table scans, index candidates, filters, joins, sorting, and result rows

  4. Plan & Evidence

    The raw plan line and source behind each metric

Evidence methodology

Evidence stays separate from explanation

Every visible value is labeled by where it comes from.
