# AzureBlobStorage Table Engine
|
|
|
|
This engine provides an integration with [Azure Blob Storage](https://azure.microsoft.com/en-us/products/storage/blobs) ecosystem.
|
|
|
|
## Create Table
|
|
|
|
``` sql
|
|
CREATE TABLE azure_blob_storage_table (name String, value UInt32)
|
|
ENGINE = AzureBlobStorage(connection_string|storage_account_url, container_name, blobpath, [account_name, account_key, format, compression])
|
|
[PARTITION BY expr]
|
|
[SETTINGS ...]
|
|
```
|
|
|
|
### Engine parameters
|
|
|
|
- `connection_string|storage_account_url` — connection_string includes account name & key ([Create connection string](https://learn.microsoft.com/en-us/azure/storage/common/storage-configure-connection-string?toc=%2Fazure%2Fstorage%2Fblobs%2Ftoc.json&bc=%2Fazure%2Fstorage%2Fblobs%2Fbreadcrumb%2Ftoc.json#configure-a-connection-string-for-an-azure-storage-account)) or you could also provide the storage account url here and account name & account key as separate parameters (see parameters account_name & account_key)
|
|
- `container_name` - Container name
|
|
- `blobpath` - file path. Supports following wildcards in readonly mode: `*`, `**`, `?`, `{abc,def}` and `{N..M}` where `N`, `M` — numbers, `'abc'`, `'def'` — strings.
|
|
- `account_name` - if storage_account_url is used, then account name can be specified here
|
|
- `account_key` - if storage_account_url is used, then account key can be specified here
|
|
- `format` — The [format](/docs/en/interfaces/formats.md) of the file.
|
|
- `compression` — Supported values: `none`, `gzip/gz`, `brotli/br`, `xz/LZMA`, `zstd/zst`. By default, it will autodetect compression by file extension. (same as setting to `auto`).

**Example**
|
|
|
|
``` sql
|
|
CREATE TABLE test_table (key UInt64, data String)
|
|
ENGINE = AzureBlobStorage('DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=http://azurite1:10000/devstoreaccount1/;',
|
|
'test_container', 'test_table', 'CSV');
|
|
|
|
INSERT INTO test_table VALUES (1, 'a'), (2, 'b'), (3, 'c');
|
|
|
|
SELECT * FROM test_table;
|
|
```
|
|
|
|
```text
|
|
┌─key──┬─data──┐
|
|
│ 1 │ a │
|
|
│ 2 │ b │
|
|
│ 3 │ c │
|
|
└──────┴───────┘
