## bigquery_add_computed_field {#metadata-bigquery-add-computed-field}
`bigquery_add_computed_field` is used to define a computed field in a BigQuery table.
There cannot be an existing column or relationship or computed field
with the same name.
Create a `computed field` called `fetch_articles` on an `author` *table*,
using an SQL function called `author_fetch_articles`:
```http
POST /v1/metadata HTTP/1.1
Content-Type: application/json
X-Hasura-Role: admin
{
"type":"bigquery_add_computed_field",
"args":{
"table":{
"name":"author",
"dataset":"hasura"
},
"source": "bigquery",
"name":"fetch_articles",
"definition":{
"function":{
"name":"author_fetch_articles",
"dataset":"hasura"
},
"argument_mapping": {
"author_id_arg": "author_id"
},
"return_table": {
"name": "article",
"dataset": "hasura"
}
}
}
}
```

| definition | true | [ComputedFieldDefinition](/graphql/core/api-reference/syntax-defs.mdx#bigquerycomputedfielddefinition) | The computed field definition |
| comment | false | `String` | Customise the description shown in GraphQL introspection. If null or omitted then if a comment exists on the database function, it is used as the description, and if not, an autogenerated description is used instead. |
## bigquery_drop_computed_field {#metadata-bigquery-drop-computed-field}
`bigquery_drop_computed_field` is used to drop a computed field of a table in a BigQuery source.
If there are other objects dependent on this computed field, like
permissions, the request will fail and report the dependencies unless
`cascade` is set to `true`. If `cascade` is set to `true`, the dependent
objects are also dropped.
Drop a computed field `fetch_articles` from a table `author`:
```http
POST /v1/metadata HTTP/1.1
Content-Type: application/json
X-Hasura-Role: admin
{
"type":"bigquery_drop_computed_field",
"args":{
"table":{
"name":"author",
"dataset":"hasura"
},
"source": "bigquery",
"name":"fetch_articles",
"cascade": false
}
}
```

# BigQuery: Computed fields
## What are computed fields?
Computed fields are virtual fields that are dynamically computed and can be
queried along with a table's columns. Computed fields are computed upon request.
They are computed by executing user-defined SQL functions using other columns of
the table and other custom inputs if needed.
:::info Note
Computed fields are only exposed over the GraphQL API and the BigQuery database
schema is not modified on addition of a computed field.
:::
### Supported SQL functions
Currently, only [table-valued functions](https://cloud.google.com/bigquery/docs/reference/standard-sql/table-functions),
which return a table, can be added as computed fields. Support for computed fields that return
a scalar type is being tracked in this [GitHub issue](https://github.com/hasura/graphql-engine/issues/8521).
#### Creating a table-valued function {#bigquery-create-table-function}
A table-valued function can be created using the [`CREATE TABLE FUNCTION`](https://cloud.google.com/bigquery/docs/reference/standard-sql/data-definition-language#create_table_function_statement)
SQL statement. BigQuery infers the returning table type based on the `RETURNS TABLE<..>` syntax present in
the SQL statement.
- If `RETURNS TABLE` is included, it specifies the custom schema of the return table as a comma-separated list
of column name and data type pairs. While [adding such functions as computed fields](#bigquery-adding-computed-field),
it is not required to provide `return_table` in the [definition](/graphql/core/api-reference/syntax-defs.mdx#bigquerycomputedfielddefinition)
as BigQuery [provides enough information](https://cloud.google.com/bigquery/docs/reference/rest/v2/routines#Routine) about
the returning table schema to Hasura.
Example:
```sql
CREATE TABLE FUNCTION `google_project.hasura_test.fetch_articles`(a_id INT64, search STRING)
RETURNS TABLE<id INT64, title STRING, content STRING> AS (
( SELECT t.id, t.title, t.content
FROM hasura_test.article t
WHERE t.author_id = a_id AND (t.title like `search` or t.content like `search`)
)
);
```
- If `RETURNS TABLE` is absent, BigQuery infers the returning table from the query statement
present in the function body, implicitly. While [adding such functions as computed fields](#bigquery-adding-computed-field),
it is required to provide `return_table` in the [definition](/graphql/core/api-reference/syntax-defs.mdx#bigquerycomputedfielddefinition)
as BigQuery does not provide any information about the returning table to Hasura.
Example:
```sql
CREATE TABLE FUNCTION `google_project.hasura_test.fetch_articles`(a_id INT64, search STRING) AS (
( SELECT t.*
FROM hasura_test.article t
WHERE t.author_id = a_id AND (t.title like `search` or t.content like `search`)
)
);
```
:::info Note
Table functions without `RETURNS TABLE` should return all columns, possibly by using the`*` operator,
to avoid any execution exceptions when a column that is not being returned is included in the selection set of
computed field.

## Computed fields permissions
[Access control](/graphql/core/auth/authorization/index.mdx) to computed fields depends on the presence of the `RETURNS TABLE` clause
in the [creating computed field](#bigquery-create-table-function) SQL statement.
If `RETURNS TABLE`
- is present, then the function returns a custom table schema. Select permissions are managed through `computed_fields`
in the [permission definition](/graphql/core/api-reference/syntax-defs.mdx#selectpermission).
- is absent, then the permissions set on `return_table` are respected.
