Lusid.Relationship.Definition

The Lusid.Relationship.Definition provider enables you to write a Luminesce SQL query that retrieves relationship types defined in LUSID.

Note: The LUSID user running the query must have sufficient access control permissions to both use the provider and read relationship type data stored in LUSID. This should automatically be the case if you are the domain owner.

Basic usage

select * from Lusid.Relationship.Definition

Query parameters

Lusid.Relationship.Definition has parameters that help you to filter or refine a query.

To list available parameters, their data types, default values, and an explanation for each, run the following query using a suitable tool:

select FieldName, DataType, ParamDefaultValue, Description from Sys.Field where TableName = 'Lusid.Relationship.Definition' and FieldType = 'Parameter';

Data fields

By default, Lusid.Relationship.Definition returns a table of data populated with particular fields (columns). You can return a subset of these fields.

To list all fields available to return, their data types, whether fields are considered 'main', and an explanation for each, run the following query using a suitable tool:

select FieldName, DataType, IsMain, IsPrimaryKey, SampleValues, Description from Sys.Field where TableName = 'Lusid.Relationship.Definition' and FieldType = 'Column';

Note: Fields marked 'main' are returned by queries that use a caret character, for example select ^ from Lusid.Relationship.Definition.
