RDB
This function returns values from a relational list that has been created with a SQL query.
Syntax
=RDB(HYPERBLOCK("hyperblock_name"),row_index,"column_title")
Using RDB inside hyperblock
The contents of relational databases are displayed on the spreadsheet using hyperblocks and SQL queries.
Drag a relational list from the Database Structure to create a hyperblock. Select the value cell and open the Edit OLAP Formula dialog. Select Relational Values as the formula type.
In the Database section, select the table and column of the relational database. The RDB formula is displayed in the OLAP formula field.
Note: Only data fields selected in the SQL query can be displayed by the RDB formula.
Using RDB outside hyperblock
Select the value cell and select .
Specify this information:
- Name
- Specify a hyperblock name
- row_index
- Specify a record or row reference.
- column_title
- Specify the name of a column from which the value is displayed.
- Use line number
- Set to TRUE to generate row index numbers as unique name of a record.
Note: The relational database does not use unique name. The unique
name is generated from first column of relational table. In this case, record
reference is the value of that unique name. Behavior of this record reference
can be changed in Advanced settings of hyperblock.
The SQL table example
| ID | Name | ElementType | OrderPosition | DataSourceID |
|---|---|---|---|---|
| Variance | Variance | NULL | 2 | NULL |
| Actual | Actual | NULL | 1 | NULL |
| Budget | Budget | NULL | 1 | NULL |
| Simulation | Simulation | NULL | 2 | NULL |
| Forecast | Forecast | NULL | 3 | NULL |
Example of the line number used as index set to FALSE
| Element Caption | Element Uniquename | ID | Name | ElementType | OrderPosition | DataSourceID |
|---|---|---|---|---|---|---|
| Variance | Variance | Variance | Variance | NULL | 2 | NULL |
| Actual | Actual | Actual | Actual | NULL | 1 | NULL |
| Budget | Budget | Budget | Budget | NULL | 1 | NULL |
| Simulation | Simulation | Simulation | Simulation | NULL | 2 | NULL |
| Forecast | Forecast | Forecast | Forecast | NULL | 3 | NULL |
Using =RDB(HYPERBLOCK("HyperblockXXX"), "Variance", "OrderPosition")
provides output value 2.
Example of the line number used as index set to TRUE
| Element Caption | Element Uniquename | ID | Name | ElementType | OrderPosition | DataSourceID |
|---|---|---|---|---|---|---|
| 1 | 1 | Variance | Variance | NULL | 2 | NULL |
| 2 | 2 | Actual | Actual | NULL | 1 | NULL |
| 3 | 3 | Budget | Budget | NULL | 1 | NULL |
| 4 | 4 | Simulation | Simulation | NULL | 2 | NULL |
| 5 | 5 | Forecast | Forecast | NULL | 3 | NULL |
Using =RDB(HYPERBLOCK("HyperblockXXX"), "3", "Name") provides output
value Budget.
