I'm using the FireDAC TFDQuery component to run a SQL SELECT statement against a SQL Server database. The SQL statement contains a few 'calculated' column expressions using SQL functions such as CONVERT and CAST. For example : CONVERT(DECIMAL(9, 6), 0) AS TotalHours and CONVERT(TINYINT, 0) AS WorkflowState. In the resulting dataset, these calculated TField objects are always set to ReadOnly=True. I want to populate these calculated fields in code after the dataset has been returned. I know I can do this by changing the ReadOnly property of each field : Dataset.FieldByName('MyCalcField').ReadOnly := False; But is there a setting/option within the query components that I can use to force the fields created to always default to ReadOnly=False?
