Record functions

These functions create and manipulate record values.

Information

Name	Description
Record.FieldCount	Returns the number of fields in a record.
Record.HasFields	Returns true if the field name or field names are present in a record.

Transformations

Name	Description
Geography.FromWellKnownText	Translates text representing a geographic value in Well-Known Text (WKT) format into a structured record.
Geography.ToWellKnownText	Translates a structured geographic point value into its Well-Known Text (WKT) representation.
GeographyPoint.From	Creates a record representing a geographic point from parts.
Geometry.FromWellKnownText	Translates text representing a geometric value in Well-Known Text (WKT) format into a structured record.
Geometry.ToWellKnownText	Translates a structured geometric point value into its Well-Known Text (WKT) representation.
GeometryPoint.From	Creates a record representing a geometric point from parts.
Record.AddField	Adds a field from a field name and value.
Record.Combine	Combines the records in a list.
Record.RemoveFields	Returns a new record that reorders the given fields with respect to each other. Any fields not specified remain in their original locations.
Record.RenameFields	Returns a new record that renames the fields specified. The resultant fields will retain their original order. This function supports swapping and chaining field names. However, all target names plus remaining field names must constitute a unique set or an error will occur.
Record.ReorderFields	Returns a new record that reorders fields relative to each other. Any fields not specified remain in their original locations. Requires two or more fields.
Record.TransformFields	Transforms fields by applying transformOperations. For more more information about values supported by transformOperations, go to Parameter Values.

Selection

Name	Description
Record.Field	Returns the value of the given field. This function can be used to dynamically create field lookup syntax for a given record. In that way it is a dynamic version of the record[field] syntax.
Record.FieldNames	Returns a list of field names in order of the record's fields.
Record.FieldOrDefault	Returns the value of a field from a record, or the default value if the field does not exist.
Record.FieldValues	Returns a list of field values in order of the record's fields.
Record.SelectFields	Returns a new record that contains the fields selected from the input record. The original order of the fields is maintained.

Serialization

Name	Description
Record.FromList	Returns a record given a list of field values and a set of fields.
Record.FromTable	Returns a record from a table of records containing field names and values.
Record.ToList	Returns a list of values containing the field values of the input record.
Record.ToTable	Returns a table of records containing field names and values from an input record.

Parameter Values

The following type definitions are used to describe the parameter values that are referenced in the Record functions above.

Type Definition	Description
MissingField option	More information: MissingField.Type
Transform operations	Transform operations can be specified by either of the following values: •  A list value of two items, first item being the field name and the second item being the transformation function applied to that field to produce a new value. •  A list of transformations can be provided by providing a list value, and each item being the list value of 2 items as described above. For examples, go to the description of Record.TransformFields
Rename operations	Rename operations for a record can be specified as either of: A single rename operation, which is represented by a list of two field names, old and new. For examples, go to the description of Record.RenameFields.
