## LINQ statement

Source: `Data/SAIF.Data/Queries/Claims/BillQueryProvider.cs:133`.

    .Query()
    .SingleOrDefault(x => x.DiagnosisCode == diagnosisInformation  && x.IcdVersionCode == icdVersion);
```

## 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.

```sql
-- Inferred from LINQ (NHibernate mapping translation); not concrete SQL
SELECT
  CD.DIAGNOSIS_CODE,
  CD.UPDATE_NUM,
  CD.ICD_VERSION_CODE,
  CD.DIAGNOSIS_DESCR,
  CD.DIAGNOSIS_SHORT_DESCR,
  CD.DIAGNOSIS_CATEGORY_CODE,
  CD.VALID_MEDICARE_REPORT_FLAG,
  CD.EFF_DATE,
  CD.EXP_DATE,
  CD.UPDATE_USER,
  CD.UPDATE_DATE
FROM CBP_DIAGNOSIS CD
WHERE CD.DIAGNOSIS_CODE = :diagnosisInformation
  AND CD.ICD_VERSION_CODE = :icdVersion
-- NHibernate expects at most one row
```
