DataverseClient Class

High-level client for Microsoft Dataverse operations.

This client provides a simple, stable interface for interacting with Dataverse environments through the Web API. It handles authentication via Azure Identity and delegates HTTP operations to an internal PowerPlatform.Dataverse.data._odata._ODataClient.

Key capabilities:

OData CRUD operations: create, read, update, delete records
SQL queries: execute read-only SQL via Web API ?sql parameter
Table metadata: create, inspect, and delete custom tables; create and delete columns
File uploads: upload files to file columns with chunking support

Note

The client lazily initializes its internal OData client on first use, allowing lightweight construction without immediate network calls.

Note

All methods that communicate with the Dataverse Web API may raise

HttpError on non-successful

HTTP responses (e.g. 401, 403, 404, 429, 500). Individual method

docstrings document only domain-specific exceptions.

Operations are organized into namespaces:

client.records – create, update, delete, and get records (single or paginated queries)
client.query – query and search operations
client.tables – table and column metadata management
client.files – file upload operations

Constructor

DataverseClient(base_url: str, credential: TokenCredential, config: DataverseConfig | None = None)

Parameters

Name	Description
base_url Required	str Your Dataverse environment URL, for example `"https://org.crm.dynamics.com"`. Trailing slash is automatically removed.
credential Required	TokenCredential Azure Identity credential for authentication.
config	DataverseConfig or None Optional configuration for language, timeouts, and retries. If not provided, defaults are loaded from from_env. Default value: None

Examples

Create a client and perform basic operations:


   from azure.identity import InteractiveBrowserCredential
   from PowerPlatform.Dataverse.client import DataverseClient

   credential = InteractiveBrowserCredential()
   client = DataverseClient(
       "https://org.crm.dynamics.com",
       credential
   )

   # Create a record
   record_id = client.records.create("account", {"name": "Contoso Ltd"})

   # Update a record
   client.records.update("account", record_id, {"telephone1": "555-0100"})

   # Query records
   for page in client.records.get("account", filter="name eq 'Contoso Ltd'"):
       for account in page:
           print(account["name"])

   # Delete a record
   client.records.delete("account", record_id)

Methods

create	Note Deprecated. Use create instead. Create one or more records by table name.
create_columns	Note Deprecated. Use add_columns instead. Create one or more columns on an existing table using a schema-style mapping.
create_table	Note Deprecated. Use create instead. Create a simple custom table with specified columns.
delete	Note Deprecated. Use delete instead. Delete one or more records by GUID.
delete_columns	Note Deprecated. Use remove_columns instead. Delete one or more columns from a table.
delete_table	Note Deprecated. Use delete instead. Delete a custom table by name. Warning This operation is irreversible and will delete all records in the table along with the table definition. Use with caution.
flush_cache	Flush cached client metadata or state.
get	Note Deprecated. Use get instead. Single record by ID – client.records.get(table, record_id) Query / filter multiple records – client.records.get(table, filter=..., select=...) Fetch a single record by ID or query multiple records. When `record_id` is provided, returns a single record dictionary. When `record_id` is None, returns a generator yielding batches of records.
get_table_info	Note Deprecated. Use get instead. Get basic metadata for a table if it exists.
list_tables	Note Deprecated. Use list instead. List all non-private tables in the Dataverse environment.
query_sql	Note Deprecated. Use sql instead. Execute a read-only SQL query using the Dataverse Web API `?sql` capability. The SQL query must follow the supported subset: a single SELECT statement with optional WHERE, TOP (integer literal), ORDER BY (column names only), and a simple table alias after FROM. Note The SQL support is limited to read-only queries. Complex joins, subqueries, and certain SQL functions may not be supported. Consult the Dataverse documentation for the current feature set.
update	Note Deprecated. Use update instead. Update one or more records. This method supports three usage patterns: Single record update: `update("account", "guid", {"name": "New Name"})` Broadcast update: `update("account", [id1, id2], {"status": 1})` - applies same changes to all IDs Paired updates: `update("account", [id1, id2], [changes1, changes2])` - one-to-one mapping Note Single updates discard the response representation for better performance. For broadcast or paired updates, the method delegates to the internal client's batch update logic.
upload_file	Note Deprecated. Use upload instead. Upload a file to a Dataverse file column.

create

Note

Deprecated. Use create instead.

Create one or more records by table name.

create(table_schema_name: str, records: Dict[str, Any] | List[Dict[str, Any]]) -> List[str]

Parameters

Name	Description
table_schema_name Required	str Schema name of the table (e.g. `"account"`, `"contact"`, or `"new_MyTestTable"`).
records Required	dict or list of dict A single record dictionary or a list of record dictionaries. Each dictionary should contain column schema names as keys.

create_columns(table_schema_name: str, columns: Dict[str, Any]) -> List[str]

Parameters

Name Description

table_schema_name

Required

str

Schema name of the table (e.g. "new_MyTestTable").

columns

Required

dict mapping str to Any

Mapping of column schema names (with customization prefix value) to supported types. All custom column names must include the customization prefix value** (e.g. "new_Notes"). Primitive types include "string" (alias: "text"), "int" (alias: "integer"), "decimal" (alias: "money"), "float" (alias: "double"), "datetime" (alias: "date"), "bool" (alias: "boolean"), and "file". Enum subclasses (IntEnum preferred) generate a local option set and can specify localized labels via __labels__.

Examples

Create multiple columns on the custom table:


   created = client.create_columns(
       "new_MyTestTable",

query_sql

Note

Deprecated. Use sql instead.

Execute a read-only SQL query using the Dataverse Web API ?sql capability.

The SQL query must follow the supported subset: a single SELECT statement with optional WHERE, TOP (integer literal), ORDER BY (column names only), and a simple table alias after FROM.

Note

The SQL support is limited to read-only queries. Complex joins, subqueries, and certain SQL functions may not be supported. Consult the Dataverse documentation for the current feature set.

query_sql(sql: str) -> List[Dict[str, Any]]

Parameters

Name	Description

Query with alias:


   sql = "SELECT a.name, a.telephone1 FROM account AS a WHERE a.statecode = 0"
   results = client.query_sql(sql)

update

Note

Deprecated. Use update instead.

Update one or more records.

This method supports three usage patterns:

Single record update: update("account", "guid", {"name": "New Name"})
Broadcast update: update("account", [id1, id2], {"status": 1}) - applies same changes to all IDs
Paired updates: update("account", [id1, id2], [changes1, changes2]) - one-to-one mapping

Note

Single updates discard the response representation for better performance. For broadcast or paired updates, the method delegates to the internal client's batch update logic.

update(table_schema_name: str, ids: str | List[str], changes: Dict[str, Any] | List[Dict[str, Any]]) -> None

Parameters

Name	Description
table_schema_name Required	str Schema name of the table (e.g. `"account"` or `"new_MyTestTable"`).
ids Required	str or list of str Single GUID string or list of GUID strings to update.
changes Required	dict or list of dict Dictionary of changes for single/broadcast mode, or list of dictionaries for paired mode. When `ids` is a list and `changes` is a single dict, the same changes are broadcast to all records. When both are lists, they must have equal length for one-to-one mapping.

Exceptions

Type	Description
TypeError	If `ids` is not str or list[str], or if `changes` type doesn't match usage pattern.

Examples

Single record update:


   client.update("account", account_id, {"telephone1": "555-0100"})

Broadcast same changes to multiple records:


   client.update("account", [id1, id2, id3], {"statecode": 1})

Update multiple records with different values:


   ids = [id1, id2]
   changes = [
       {"name": "Updated Name 1"},
       {"name": "Updated Name 2"}
   ]
   client.update("account", ids, changes)

upload_file

Note

Deprecated. Use upload instead.

Parameters

Name	Description
table_schema_name Required	str Schema name of the table.
record_id Required	str GUID of the target record.
file_name_attribute Required	str Schema name of the file column attribute.
path Required	str Local filesystem path to the file.
mode	str Upload strategy: `"auto"` (default), `"small"`, or `"chunk"`. Default value: None
mime_type	str Explicit MIME type to store with the file. Default value: None
