All content below this line refers to {{#multireplace:FireDAC.Comp.DataSet.TFDDataSet.DetailFields|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
Gets or sets the fields in the detail dataset that are used to establish a master-detail relationship with this dataset.
Use the DetailFields property value to specify a semicolon-separated list of the detail dataset field names used to establish a master-detail relationship with this dataset.
The DetailFields property is useful only for parameter-based master-detail setup. For range-based setup, the indexed fields are used as the detail field list. When DetailFields is not specified explicitly, the field names matching a query in the parameter names will be used as DetailFields value.
DetailFields are used only to assign specified field values when a new record is inserted into a detail dataset. The mechanism used to filter the detail dataset records does not use DetailFields.
