This should automatically be the case if you are the domain owner. **See also:** [Lusid.Portfolio.Txn](/v1/docs/lusidportfoliotxn), [Lusid.Portfolio.Txn.Property.Writer](/v1/docs/lusidportfoliotxnpropertywriter) ## Basic usage ```sql select * from Lusid.Portfolio.Txn.Property where ; ``` ## Query parameters `Lusid.Portfolio.Txn.Property` has parameters that enable 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](/v1/docs/what-tools-are-available-to-write-luminesce-queries): ```sql select FieldName, DataType, ParamDefaultValue, Description from Sys.Field where TableName = 'Lusid.Portfolio.Txn.Property' and FieldType = 'Parameter'; ``` ## Data fields By default, `Lusid.Portfolio.Txn.Property` returns a table of data populated with particular fields (columns). You can return just a subset of these fields if you wish. To list 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](/v1/docs/what-tools-are-available-to-write-luminesce-queries): ```sql select FieldName, DataType, IsMain, IsPrimaryKey, SampleValues, Description from Sys.Field where TableName = 'Lusid.Portfolio.Txn.Property' and FieldType = 'Column'; ``` > [!NOTE] > **Note:** Fields marked 'main' are returned by queries that start select ^ from Lusid.Portfolio.Txn.Property... ## Examples > [!NOTE] > **Note:** For more example Luminesce SQL queries, visit our [Github repo](https://github.com/finbourne/luminesce-examples/tree/master/examples). ### Example 1: Retrieve custom properties for transactions across all portfolios ```sql select * from Lusid.Portfolio.Txn.Property ``` ### Example 2: Retrieve transactions that have a particular property and property value You can select a particular property value for your filter expression, for example the NYSE exchange code. ```sql select * from Lusid.Portfolio.Txn.Property where PropertyCode = 'ExCo' and Value = 'NYSE' ``` ### Example 3: Retrieve transactions that have a particular property value, and display transaction details You can join `Lusid.Portfolio.Txn.Property` to an entity provider such as `Lusid.Portfolio.Txn` to retrieve transaction details, such as `TradePrice`, `TradeAmount` and so on, though only for a particular transaction property. ```sql select    t.TxnId,    t.LusidInstrumentId as 'Lusid Instrument ID',    t.TradePrice,    t.TradeAmount,    t.TradeCurrency,    tp.PortfolioScope,    tp.PortfolioCode,    tp.Value as 'Exchange Code' from Lusid.Portfolio.Txn.Property tp inner join Lusid.Portfolio.Txn t    on t.TxnId = tp.TxnId where tp.PortfolioScope = 'Finbourne-Examples' and tp.PropertyCode = 'ExCo' ```
