# SQL-016: Coverage gap retrieval

`clsPolicyData` uses this call to list the periods during which a policy had no coverage in force. The procedure derives gaps from adjacent period boundaries and unions any explicitly recorded gaps.

## Classification

| Field | Value |
| --- | --- |
| **SQL ID** | SQL-016 |
| **Operation type** | Read |
| **Execution method** | Stored procedure |
| **Database** | Oracle |
| **Schema** | `[unqualified]`** |
| **Command type** | StoredProcedure |
| **Business object** | `clsPolicyData` |
| **Criteria property** | N/A (ad hoc, literal `SQLStatement`) |
| **Lifecycle method** | `Gaps` property getter |

## Parameters

| Parameter | Direction | Type | Max length | Description |
| --- | --- | --- | --- | --- |
| `:aPolicyNum` | Input | Decimal | not specified | Policy number whose coverage gaps are requested. |
| `recordset` | Output (Cursor) | REF CURSOR | N/A | Result set of gap begin and end date pairs. |

## Tables

No table is referenced directly in the .NET source. The tables read by the procedure body reside in the Oracle database and are described under [pk72846_view_policy](../procedures/pk72846_view_policy.md).

## Sample SQL

```sql
-- Stored procedure call (procedure body resides in the Oracle database - WCIS_DBA.pk72846_view_policy)
CALL pk72846_view_policy.getgaps(
  aPolicyNum => :aPolicyNum,
  recordset  => :recordset)  -- REF CURSOR output
```

## Operations and processes

> **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.
