GetViewStructure()

Retrieves a listing and description of the fields in a view.

In Version 2013 added field types "Date", "Time", and "DateTime."

field_info = GetViewStructure(string view_name)

Argument	Contents
view_name	Name of a view

An array with one element for each field in the view. Each element is an array with the following structure:

Element	Type	Contents
1	String	Field name
2	String	Field type: "String", "Integer", "Real", "Date", "Time", or "DateTime"
3	Integer	Number of characters (bytes) per record for this field in the file, i.e., the internal field width
4	Integer	Number of decimals
5	Boolean	A flag ("True" or "False") that indicates whether the field is internally (permanently) indexed

All returned values describe the view, not the underlying table. As a result, functions such as RenameField() and SetFieldWidth() affect the returned values. To determine the structure of a table, use GetTableStructure() instead.
The returned array includes expression fields in the view.
GetViewStructure() can be used on joined views.
If the input view_name is null, GetViewStructure() uses the current view.
GetViewStructure() returns a field_info_array that can be used as an input to the CreateTable() function to create a new (emtpy) table with the same field characteristics.

Error Type	Meaning
NotFound	The named view does not exist, or view_name is null and there is no current view

Function	Summary
GetTableStructure()	Gets a list and description of the fields in a table
CreateTable()	Creates an empty table and opens it as a view
RenameField()	Renames a field in a view
SetFieldWidth()	Changes the display width of a field
SetFieldDecimals()	Changes the number of displayed decimals for a real-typed field
