GETS A VECTOR COLUMN FROM A DATABASE¶
Retrieves a single named vector column from a d3VIEW database record and returns its values as a vector. Use this worker when a downstream step needs one array-valued column from a structured database without loading the entire table.
When to use¶
Tagged: column, database, datarecord, fetch, remote_lookup, vector.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Database | database_id | remote_lookup | — | ✓ | Remote reference to the target d3VIEW database (datarecord); select from the platform database registry — required, no default. |
| Column Name | column_name | text | — | ✓ | Exact name of the vector-typed column to retrieve from the selected database; case-sensitive, must match the column header stored in the record. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Database Id | database_id | scalar | Pass-through reference to the source database that was queried, enabling downstream workers to chain further operations on the same record. |
| Column Data | column_data | vector | The extracted column returned as a numeric or string vector; length equals the number of rows in the database for that column. |
