Command syntax

Description

Gets the type of a ReQL query’s return value.

The type will be returned as a string:

• ARRAY
• BOOL
• DB
• FUNCTION
• GROUPED_DATA
• GROUPED_STREAM
• MAXVAL
• MINVAL
• NULL
• NUMBER
• OBJECT
• PTYPE<BINARY>
• PTYPE<GEOMETRY>
• PTYPE<TIME>
• SELECTION<ARRAY>
• SELECTION<OBJECT>
• SELECTION<STREAM>
• STREAM
• STRING
• TABLE_SLICE
• TABLE

Read the article on ReQL data types for a more detailed discussion. Note that some possible return values from type_of are internal values, such as MAXVAL, and unlikely to be returned from queries in standard practice.

Example: Get the type of a string.

> r.expr("foo").type_of().run(conn)
"STRING"
