Windows Data Model

Catalog: FileSystem

Label: File Metadata Properties

This is a read-only table function. The Windows API may not support changing the data or the Invantive SQL driver for Windows does not cover it. In the latter case, please use the table NativePlatformScalarRequests to upload data to the Windows API.

Table Function Parameters

The following parameters can be used to control the behaviour of the table function file_info. A value must be provided at all times for required parameters, but optional parameters in general do not need to have a value and the execution will default to a pre-defined behaviour. Values can be specified by position and by name. In both cases, all parameters not specified will be treated using their default values.

Value specification by position is done by listing all values from the first to the last needed value. For example with `select * from table(value1, value2, value3)` on a table with four parameters will use the default value for the fourth parameter and the specified values for the first three.

Value specification by name is done by listing all values that require a value. For example with `select * from table(name1 => value1, name3 => value3)` on the same table will use the default values for the second and fourth parameters and the specified values for the first and third.

Table Function Columns

The columns of the table function file_info are shown below. Each column has an SQL data type.
