Fields

Fields

A field is a subset of a data structure that represents a single data item. For example, a database table column is a field. Use this resource to request field details for a source or target object and to update the flat file attributes for a source or target object.

GET request

Request field details of a source object or a target object.
  • To request the field details of a source object, use the source connection ID or source connection name and the source object name. Use one of the following URIs:
    /api/v2/connection/source/<id>/field/<object name>
    /api/v2/connection/source/name/<name>/field/<object name>
  • To request the field details of a target object, use the target connection ID or target connection name and the target object name. Use one of the following URIs:
    /api/v2/connection/target/<id>/field/<object name>
    /api/v2/connection/target/name/<name>/field/<object name>
If you use the connection name in the URI and the connection name includes a space, replace the space with
%20
. For example:
/api/v2/connection/source/name/my%20connection/field/customer
You can also use the following URI, which accommodates searching for an object that includes a forward slash (/):
/api/v2/connection/<source or target>/<id>/fields?objectName=<objectName>
The object name is case-sensitive.

GET response

Returns the field object for each field in the requested object.
Returns the error object if errors occur.
The field object includes different information based on the connection type. The following attributes might be returned in a field object:

GET example

To get the field details for the Customer object available through the source connection (ID: 0002D420000000J), you might use the following request:
GET <serverUrl>/api/v2/connection/source/0002D420000000J/field/Customer Content-Type: application/xml Accept: application/xml icSessionId: <icSessionId>
A successful request returns the fields object for each field in the Customer source object.

POST request for flat file attributes

You can use a POST request to update flat file attributes for a flat file connection.
Use one of the following URI:
/api/v2/connection/source/<id>/field/<objectName> /api/v2/connection/target/<id>/field/<objectName>
When you send a request to change flat file attributes, the flat file attributes provided in the request override the default attributes specified in the connection object.
To change flat file attributes, include the following information in the flatFileAttrs object:
Field
Type
Required
Description
id
Long
Yes
Field ID.
delimiter
String
Yes
Character used to separate fields.
textQualifier
String
Yes

multiDelimitersAsAnd
Boolean
--
If the delimiter you specify is more than one character, indicates whether the characters are treated as a single delimiter or multiple delimiters.
Default is true.

POST request example for flat file attributes

To send a request for field information for a flat file connection, you might use the following request:
POST <serverUrl>/api/v2/connection/source/0000010B000000000021/field/test_precision.csv 1.0 Content-Type: application/xml Accept: application/xml icSessionId { "@type": "flatFileAttrs", "delimiter": ",", "textQualifier": "'", "escapeChar": "\\" }

POST request for non-flat file formats

For Avro, Parquet, Orc, and JSON formats, you can receive field information by including the format type and optionally, the schema. If you don't include the schema, the schema format is inferred from the data file.
Use one of the following URIs:
/api/v2/connection/source/<id>/fields?objectName=<object name> /api/v2/connection/target/<id>/fields?objectName=<object name>
You can use the following attributes in the dataFormat object:
Field
Type
Required
Description
formatId
String
Yes
Format type, for example, Avro.
schema
String
--
Schema format.

POST request example for a non-flat file formats

To send a request for field information for a Parquet connection, you might use a request that is similar to the following example:
POST <serverUrl>/api/v2/connection/source/0100000B00000000000F/fields?objectName=infa.qa.bucket%2Fcustomer.parquet 1.0 Content-Type: application/xml Accept: application/xml icSessionId: <icSessionId> { "@type": "dataFormat", "dformatId": "Parquet", "schema": "message AllData_root { optional int32 c_custkey; optional binary c_name (UTF8); optional binary c_address (UTF8); optional int64 c_nationkey; optional binary c_phone (UTF8); optional double c_acctbal; optional binary c_mktsegment (UTF8); required binary c_comment (UTF8);}" }
A successful response might look like the following example:
[ { "@type": "field", "id": -1, "name": "c_custkey", "type": "parquet_int32", "uniqueName": "c_custkey", "label": "c_custkey", "parentObject": "customer_tgt.parquet", "pcType": "INTEGER", "precision": 10, "scale": 0, "columnIndex": -1, "isKey": false, "isExternalId": false, "isSfIdLookup": false, "isNullable": true, "isUnique": false, "isCreateable": false, "isUpdateable": true, "isFilterable": true, "isCalculated": false, "javaType": "java.lang.Integer", "showLabel": true, "naturalOrder": 0, "linkedFields": [], "relatedInfos": [], "references": [] }, { "@type": "field", "id": -1, "name": "c_address", "type": "parquet_string", "uniqueName": "c_address", "label": "c_address", "parentObject": "customer_tgt.parquet", "pcType": "NSTRING", "precision": 4000, "scale": 0, "columnIndex": -1, "isKey": false, "isExternalId": false, "isSfIdLookup": false, "isNullable": true, "isUnique": false, "isCreateable": false, "isUpdateable": true, "isFilterable": true, "isCalculated": false, "javaType": "java.lang.String", "showLabel": true, "naturalOrder": 2, "linkedFields": [], "relatedInfos": [], "references": [] }, { "@type": "field", "id": -1, "name": "c_nationkey", "type": "parquet_int64", "uniqueName": "c_nationkey", "label": "c_nationkey", "parentObject": "customer_tgt.parquet", "pcType": "BIGINT", "precision": 19, "scale": 0, "columnIndex": -1, "isKey": false, "isExternalId": false, "isSfIdLookup": false, "isNullable": true, "isUnique": false, "isCreateable": false, "isUpdateable": true, "isFilterable": true, "isCalculated": false, "javaType": "java.math.BigInteger", "showLabel": true, "naturalOrder": 3, "linkedFields": [], "relatedInfos": [], "references": [] }, { "@type": "field", "id": -1, "name": "FileName", "type": "string", "uniqueName": "FileName", "label": "FileName", "parentObject": "customer_tgt.parquet", "pcType": "NSTRING", "precision": 1024, "scale": 0, "columnIndex": -1, "isKey": false, "isExternalId": false, "isSfIdLookup": false, "isNullable": false, "isUnique": false, "isCreateable": false, "isUpdateable": true, "isFilterable": true, "isCalculated": false, "javaType": "java.lang.String", "showLabel": true, "naturalOrder": 8, "linkedFields": [], "relatedInfos": [], "references": [] } ]
