## Narrative

**Business context:** Quotation reporting — renders a JSON parameter list as a human-readable string for display on the printed quotation. Each parameter row has a code (`sParamKey`), label (`sParamName`), and value (`sParamValue`); the output collapses them into `name:【value】;name:【value】;…` form.

**What it does:** uses `JSON_TABLE` to fan the JSON array out into rows and `GROUP_CONCAT` to assemble the display string. Pure transformation; no schema dependencies.

**Invocation:** called only by `Sp_reportdata_Quo_JT` — the data-prep proc behind the JT-flavoured quotation report template.
