# MIKE+ Parameters Reads and edits values in the MIKE+ model database tables (via mikeplus). This is the "edit the model" capability that sits between `mike-model` (overview) and `mike-runner` (execute). ## Tools - **`mike_get_values`** — `{sqlite, table, columns?, muids?}` → current values. Read-only. Use to **identify** a parameter before changing it. - **`mike_set_values`** — `{sqlite, table, values, muids | all}` → applies the change and returns **before/after** for the affected rows. **Mutates** the database. ## Common tables / columns - `msm_Link` — pipes/reaches: `Diameter`, `Width`, `Height`, `Manning` (Manning's M; higher = smoother), `MaterialID`, `TypeNo`. - `msm_Node` — manholes/nodes: `GroundLevel`, `InvertLevel`, `Diameter`. - `msm_Catchment` — catchments: area / imperviousness / runoff parameters. - `msm_Project` — simulation setups (used by `mike_run`'s `simulation`). ## Conventions (safety) - **Always operate on a COPY** — `mike_set_values` writes to the database and mikeplus has no undo. - **Scope every edit.** Pass `muids` to target specific elements; only set `all=true` when you truly mean every row. - Confirm with the returned `before`/`after` (or a follow-up `mike_get_values`) before re-running. - **Edit with the Base scenario active** (or a scenario that shares Base's alternatives). Under a scenario with its own alternatives mikeplus cannot write and the tool errors "did not persist"; a variant for comparison is a second model COPY, not a scenario (
