Reference Table
Table Description
The d_references table contains information on all encoded data fields of the SICDB dataset. To simplify JOIN and other types of subqueries each reference value has an unique global identifier.
Raw Fields
| Name | Description | Comment |
|---|---|---|
| ReferenceGlobalID | The unique ID for the reference | Use this identifier as dictionary for alle encoded fields |
| ReferenceValue | Reference value | i.e. "male" |
| ReferenceName | The name of the reference | i.e. "sex" |
| ReferenceOrder | Default order of reference | i.e. KDIGO_0=0, KDIGO_1=1 (used in further releases) |
| ReferenceType | Type of reference if applicable | i.e. Laboratory, Medication ... (used in further releases) |
| ReferenceSubtype | Subtype of reference if applicable | i.e. Crystalloid, Colloid (used in further releases) |
| Caption | Caption of reference | May be used in future for translation |
| DefaultChartConfig | Some data can be visualized in charts (RooDataServer), this metadata defines how | |
| CustomFieldID | Used for user-defined data | (used in further releases) |
Usage Information
d_references is the dictionary for all encoded data.
Raw Data
For raw data replace the value (i.e. Laboratory.LaboratoryID) with the value of d_references.ReferenceValue where Laboratory.LaboratoryID = d_references.ReferenceGlobalID
SQL
Use a join query to get the reference value.
Example:
SELECT Sex,SexRef.ReferenceValue as SexCaption FROM `cases` INNER JOIN d_references as SexRef ON SexRef.ReferenceGlobalID = cases.Sex;
RooDataServer
All fields using references provide simple filters to select references. On export RooDataServer will per default export the text value of an encoding.
Note
To reduce the amount of tables there is no table describing references as there is no significant gain of information expected. This may change in later versions of dataset. To enumerate a reference use table d_references.ReferenceName, which is an immutable, case sensitive key to a reference.
