docs: Clarify that aggregations aren't supported for implicit types.
You can't `sum` an `INTERVAL`, unfortunately. I also removed _docs/.yarnrc_ as it seems to be unused; _docs/.yarnrc.yml_ is the new <del>shit</del> <ins>stuff</ins>.

Introduction
|
||||
------------
|
||||
|
||||
List of MS SQL Server types supported by the Hasura GraphQL Engine with their equivalent Hasura types:
|
||||
|
||||
.. csv-table::
|
||||
:file: mssqltypes.csv
|
||||
:widths: 13, 11, 25, 6
|
||||
:header-rows: 1
|
||||
|
||||
.. _Int:
|
||||
|
||||
Int
|
||||
---
|
||||
GraphQL default scalar with name **Int**.
|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
objects: [
|
||||
{
|
||||
int_col: 27
|
||||
}
|
||||
]
|
||||
|
||||
.. _Float:
|
||||
|
||||
Float
|
||||
-----
|
||||
GraphQL custom scalar type with name **float8**.
|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
objects: [
|
||||
{
|
||||
float_col: 0.8
|
||||
}
|
||||
]
|
||||
|
||||
.. note::
|
||||
|
||||
To avoid loss of data when retrieving IEEE 754 style data from the database,
|
||||
please refer to the :ref:`server_flag_reference` for instructions on setting
|
||||
the ``extra_float_digits`` parameter, which has a bad default value in
|
||||
PostgreSQL 11 and older.
|
||||
|
||||
.. _Numeric:
|
||||
|
||||
Numeric
|
||||
-------
|
||||
GraphQL custom scalar type with name **numeric**.
|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
objects: [
|
||||
{
|
||||
numeric_col: 0.00000008
|
||||
}
|
||||
]
|
||||
|
||||
.. _Bool:
|
||||
|
||||
Bool
|
||||
----
|
||||
GraphQL default Scalar with name **Boolean**. The **Boolean** scalar type represents ``true`` or ``false``.
|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
objects: [
|
||||
{
|
||||
is_published: true
|
||||
}
|
||||
]
|
||||
|
||||
.. _Char:
|
||||
|
||||

||||
]
|
||||
|
||||
|
||||
.. _String:
|
||||
|
||||

|
||||
------
|
||||
GraphQL default scalar with name **String**. The **String** scalar type represents textual data, represented as UTF-8 character sequences.
|
||||

||||
E.g.
|
||||
|
||||
.. code-block:: graphql

|
||||
(e.g. 17:30:15Z, 17:30:15+05:30, 17:30:15.234890+05:30).
|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||

|
||||
{
|
||||
time: "17:30:15+05:30"
|

|
||||
|
||||
.. _Timestamptz:

|
||||
|
||||

|
||||
{
|
||||
timestamptz_col: "2016-07-20T17:30:15+05:30"

||||
|
||||
.. _JSON:

||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||

.. _JSONB:
|
||||
|
||||
JSONB
|
||||
-----
|
||||
GraphQL custom scalar type with name **jsonb**. Value should be given through a variable of type **jsonb**.
|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
mutation insert_test($value : jsonb) {
|
||||
insert_test(
|
||||
objects: [
|
||||
{
|
||||
jsonb_col: $value
|
||||
}
|
||||
]
|
||||
) {
|
||||
affected_rows
|
||||
returning{
|
||||
jsonb_col
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
variables:
|
||||
|
||||
.. code-block:: json
|
||||
|
||||
{
|
||||
"value": {
|
||||
"name": "raven"
|
||||
}
|
||||
}
|
||||
|
||||
.. _Geometry:
|
||||
|
||||

||||
--------
|
||||
|
||||
GraphQL custom scalar type ``geometry`` is generated for a ``GEOMETRY`` column
|
||||
on a PostGIS enabled MS SQL Server instance. Value should be given as GeoJSON.
|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
mutation insertGeometry($point: geometry!) {
|
||||
insert_test(
|
||||
objects: [{
|
||||
geometry_col: $point
|
||||
}]
|
||||
) {

|
||||
returning {
|
||||
geometry_col
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
variables:
|
||||
|
||||
.. code-block:: json
|
||||
|
||||
{
|
||||
"point": {
|
||||

|
||||
|
||||
|
||||
.. _Geography:
|
||||
|
||||
Geography
|
||||
---------
|
||||
|
||||
GraphQL custom scalar type ``geography`` is generated for a ``GEOGRAPHY`` column
|
||||

|
||||
|
||||
E.g.
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
mutation insertGeography($point: geography!) {
|
||||
insert_test(
|
||||
objects: [{
|
||||
geography_col: $point
|
||||
}]
|
||||
) {
|
||||
affected_rows
|
||||
returning {
|
||||

|
||||
}
|
||||
}
|
||||

|
||||
|
||||
.. _Implicit:
|
||||
|
||||
Implicitly Supported types
|
||||
--------------------------
|
||||
All ``Implicit`` types in the :ref:`above table <ms_sql_server_types_table>` are implicitly supported by the GraphQL Engine. You have to
|
||||
provide the value as a **String**.
|
||||
|
||||
|
||||
E.g. For time without time zone type
|
||||
|
||||
In ISO 8601 format
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
objects: [
|
||||
{
|
||||
time_col: "04:05:06.789"
|
||||
}
|
||||
]
|
||||
|
||||
E.g. For macaddr type
|
||||
|
||||
.. code-block:: graphql
|
||||
|
||||
objects: [
|
||||
{
|
||||
macaddr_col: "08:00:2b:01:02:03"
|
