|---|---|
| SQL ID | SQL-147 |
| Operation type | Read |
| Execution method | ORM (NHibernate LINQ) |
| Database | Oracle* |
| Schema | Unknown** |
| Command type | N/A (ORM-generated) |
| Business object | ImageQueryProvider |
| Criteria property | N/A — ORM |
| Lifecycle method | GetImage |
Parameters¶
| Parameter | Direction | Type | Max length | Description |
|---|---|---|---|---|
imageId |
Input | long | N/A | Method argument of ImageQueryProvider.GetImage bound into the ORM expression; NHibernate generates the bind variable at runtime |
Tables¶
| Table | Access | Columns used |
|---|---|---|
image** |
SELECT | unresolved (see Unresolved mapping) |
LINQ statement¶
Source: Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:20. The repository is obtained at Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:15.
// Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:15
repository = Factory.GetRepository<Image>().Query();
// Data/SAIF.Data/Queries/Policies/Images/ImageQueryProvider.cs:20
return repository.SingleOrDefault(x => x.Id == imageId);
Sample SQL¶
Inferred SQL: This SQL was inferred from the LINQ statement above and the NHibernate mappings. It is not concrete SQL from source code; NHibernate generates the executed statement at runtime, so aliases, column order, join syntax, and bind-parameter names may differ.
-- Inferred from LINQ (NHibernate mapping translation); not concrete SQL
SELECT
<all mapped columns of Image> -- unresolved mapping: Image column list not documented
FROM image I
WHERE I.<Id column> = :imageId -- unresolved mapping: Image.Id
-- NHibernate expects at most one row
Translation notes:
- The ** table marker means the mapping is external (SAIF.Framework.Data.NHibernate). The table name is confirmed; the columns are unresolved.
Operations and processes¶
Note: Statements marked with
**could not be confirmed; treat as unknown until verified.
