box.schema.func.create()

box.schema.func.create(func-name[, {options}])

Create a function tuple. This does not create the function itself – that is done with Lua – but if it is necessary to grant privileges for a function, box.schema.func.create must be done first. For explanation of how Tarantool maintains function data, see reference on _func space.

The possible options are:

• if_not_exists = true|false (default = false) - boolean; true means there should be no error if the _func tuple already exists.
• setuid = true|false (default = false) - with true to make Tarantool treat the function’s caller as the function’s creator, with full privileges. Remember that SETUID works only over binary ports. SETUID doesn’t work if you invoke a function via an admin console or inside a Lua script.
• language = ‘LUA’|’C’ (default = ‘LUA’).

Parameters:	func-name (string) – name of function, which should conform to the rules for object names options (table) – if_not_exists, setuid, language.
Return:	nil

Example:

box.schema.func.create('calculate')
box.schema.func.create('calculate', {if_not_exists = false})
box.schema.func.create('calculate', {setuid = false})
box.schema.func.create('calculate', {language = 'LUA'})
