# SQL-VP-031 Retrieve WCIS-era payroll classification detail

Selected in `clsPayrollClassInfoCollection.BeforeRetrieve` when no `ClassCoverageSetID` is supplied
(the WCIS-era branch); the alternate PMS-era branch is
[SQL-VP-030](SQL-030-retrieve_pms_sql.md). Composed of a `UNION` of a "with federal minimum wage"
branch and a fallback branch without it.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-VP-031 |
| **Operation type** | Read |
| **Execution method** | Inline SQL (constant, reconstructed from VB `& _` continuations, `UNION`) |
| **Database** | Oracle |
| **Schema** | `[unqualified]**` |
| **Command type** | Text |
| **Business object** | `clsPayrollClassInfoCollection` (via `clsPayrollClassInfo.RETRIEVE_WCIS_SQL`) |
| **Criteria property** | `BeforeRetrieve` (branch: else) |
| **Lifecycle method** | `BeforeRetrieve` / `AfterRetrieve` |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `prem_hist_set_id` | Input | Decimal/ID | N/A | Premium-history set ID identifying the WCIS-era detail set. |
| `period_start_date` | Input | Date | N/A | Policy period start date filter. |
| `period_end_date` | Input | Date | N/A | Policy period end date filter. |

## Tables

| Table | Access | Columns used |
| --- | --- | --- |
| [PREM_HIST_CLASS_COVERAGE](../database-tables.md#prem_hist_class_coverage) | SELECT / JOIN | `PREM_HIST_SET_ID`, `MANUAL_CLASS_CODE`, `PAYROLL_AMOUNT` |
| [MANUAL_CLASS_DESCRIPTION](../database-tables.md#manual_class_description) | JOIN | `MANUAL_CLASS_CODE`, `MANUAL_CLASS_DESCRIPTION` |
| [PREM_HIST_ADJ_RATE_CLASS](../database-tables.md#prem_hist_adj_rate_class) | JOIN | `PREM_HIST_SET_ID`, `RATE` |
| [POLICY_PERIOD](../database-tables.md#policy_period) | JOIN | `PREM_HIST_SET_ID`, `POLICY_NUM`, `PERIOD_START_DATE`, `PERIOD_END_DATE`, `POLICY_PERIOD_EFF_DATE` |
| [LOCATION](../database-tables.md#location) | JOIN | `POLICY_NUM`, `LOCATION_SEQ_NUM` |
| [FEDERAL_MINIMUM_WAGE](../database-tables.md#federal_minimum_wage) | LEFT JOIN | `EFF_DATE`, `EXP_DATE`, `MINIMUM_WAGE_RATE` |

*Reconstructed from the very large multi-line VB `& _` concatenated `RETRIEVE_WCIS_SQL` constant
spanning both a "with federal minimum wage" branch and a `UNION` fallback branch without it; exact
column aliases/join predicates are inferred from the concatenated string structure captured across
multiple source reads and should be spot-checked against the live constant before being treated as
byte-exact.*

> **Note:** Statements marked with `*` were inferred from code structure, naming
> conventions, or contextual evidence where direct confirmation was not available
> in source artifacts. Statements marked with `**` could not be confirmed; treat
> as unknown until verified.
