The following are the properties for Delimited File metadata. Note that you can connect to Delimited or Csv Files directly through the activity or action in your project (if the file fields can be defined from a unique source).
You only need to define the metadata if you want to reuse the definition in future projects or if the fields are not derived from an existing data source (for example to specify a csv target mixing fields from different sources).
FileDefinitionName
Datasource name, enter a unique name for the file definition.
File Path
The default file path to automatically load file fields from an existing csv file
File Fields
Define a collection of fields in the file (when creating the metadata, this collection is empty and will be generated from the file and separator specified in the File Path and Field Separator properties.
Field Separator
Define the field separator character
The following are the properties for Fixed Length File metadata.
FileDefinitionName
Enter a unique name for the file definition.
FileFields
Define a collection of fields in the file
FilePath
The default file path. You can override this value in your projects.
The connector for CSV allows connecting to local and remote CSV resources. Set the URI property to the CSV resource location, in addition to any other properties necessary to connect to your data source.
Set the URI to a folder containing CSV files.
Below is an example connection string:
You can also connect to multiple CSV files which share the same schema. Below is an example connection string:
If you would prefer to expose all of the individual CSV files as tables instead, leave this property False.
Set the URI to the HTTP or HTTPS URL of the CSV resource you want to access as a table. For example:
To authenticate, set AuthScheme and the corresponding properties. Specify additional headers in CustomHeaders to modify the query string, set CustomUrlParams.
To query the CSV stream, reference streamedtable as the table name.
Set the URI to the bucket and folder. Additionally, set the following properties to authenticate:
AWSAccessKey: Set this to an Amazon Web Services Access Key (a username).
AWSSecretKey: Set this to an Amazon Web Services Secret Key.
For example:
Optionally, specify AWSRegion in addition.
Note: It is also possible to connect to S3-compatible services by specifying its base StorageBaseURL. For example, if the StorageBaseURL conn prp is set to http://s3.%region%.myservice.com and Region is region-1, then we will generate request URLs like https://s3.region-1.myservice.com/bucket/... (or like https://bucket.s3.region-1.myservice.com/..., if the UseVirtualHosting property is true).
Set the URI to the bucket and folder. Additionally, set the following properties to authenticate:
AWSAccessKey: Set this to an Oracle cloud Access Key.

Set the URI to the name of your container and the name of the blob. Additionally, set the following properties to authenticate:
AzureStorageAccount: Set this to the account associated with the Azure blob.
AzureAccessKey: Set this to the access key associated with the Azure blob.
For example:
You can also use the OAuth authentication to connect with Azure Blob Storage. For example:
If you are connecting from an Azure VM with permissions for Azure Blob storage, you can simply use the AzureMSI AuthScheme For example:
If you would like to authenticate with a service principal instead of a client secret, it is also possible to authenticate with a client certificate.
InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
AzureTenant: Set this to the tenant you wish to connect to.
OAuthGrantType: Set this to CLIENT.
OAuthClientId: Set this to the Client Id in your app settings.
OAuthJWTCert: Set this to the JWT Certificate store.

For example:
You can also use the OAuth authentication to Connect with Azure Data Lake Store Gen 2. For example:
If you are connecting from an Azure VM with permissions to connect to Azure Data Lake Store Gen 2, you can simply set AuthScheme to AzureMSI. For example:
If you would like to authenticate with a service principal instead of a client secret, it is also possible to authenticate with a client certificate.
InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.

For example:
Set the URI to the path to a folder containing CSV files. To authenticate to Box, use the OAuth authentication standard. See the Box Connector for an authentication guide.
For example:
Set the URI to the path to a folder containing CSV files. To authenticate to Dropbox, use the OAuth authentication standard. See the Dropbox Connector for an authentication guide. You can authenticate with a user account or a service account. In the user account flow, you do not need to set any connection properties for your user credentials, as shown in the connection string below:
Set the URI to the path to the name of the file system and the name of the folder which contacts your CSV files. To access shared files, set SharedWithMe as the name of the folder which contains your Excel files. For example URI=gdrive://SharedWithMe/remotePath. To authenticate to Google APIs, use the OAuth authentication standard. You can authorize the provider to connect to Google APIs on behalf of individual users or on behalf of a domain. See the Google Drive Connector data source.
For example:
Set the URI to a document library containing CSV files. To authenticate, set User and Password and StorageBaseURL.
For example:
Note that this connection method may not work if the StorageBaseURL ends with "-my.sharepoint.com". You should use the onedrive:// scheme when connecting to these sites because they do not support the components that of SharePoint that the provider needs to download files.
Set the URI to a document library containing CSV files. StorageBaseURL is optional. If not provided, the driver will work with the root drive. To authenticate, use the OAuth authentication standard.
For example:
Note that this connection method may not work if the StorageBaseURL ends with "-my.sharepoint.com". You should use the onedrive:// scheme when connecting to these sites because they do not support the components that of SharePoint that the provider needs to download files.
Set the URI to the address of the server followed by the path to the folder to be used as the root folder. To authenticate, set User and Password.
For example:
Set the URI to the path to the name of the file system and the name of the folder which contacts your CSV files. To authenticate to Google APIs, provide a ProjectId.
For example:
By default, the connector attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats to do so.
The following are the connection properties for CSVDatabase. Not all properties are required. Enter only property values pertaining to your installation. Several properties will be automatically initialized with the appRules defaults.
