Description

TPutFieldInfo is a record containing information about a field. TPutFieldInfo is used when adding a new field to a dataset. TPutFieldInfo fields are listed in the following table.

Field	Meaning
FieldNo	The position of the field (column) in the underlying database table.
Field	The actual field component.
DataSet	Identifies the dataset to which the field component belongs.
Size	Indicates the size used in the definition of the physical database field for data types that support different sizes.
IsDetail	Specifies whether the field is linked to a dataset.
Opened	Specifies whether the linked dataset is active, in the case when the field is linked to a dataset.
PutProc	Stores the procedure used to add the field to the dataset.
LocalFieldIndex	Index variable used internally.
FieldInfos	In the case when the field is linked to a dataset, FieldInfos contains information about all the fields in the linked dataset. To access the information about the fields, do a typecast on FieldInfos to a TInfoArray.
