o()

Here are how to use o() functions.

A.o()

Description:

Convert a sequence to an ordinary one.

Syntax:

A.o()

Note:

The function converts sequence A, which can be an ordinary sequence or a pure sequence to an ordinary sequence. When the computation involves an ordinary sequence or when it is expected that the result of the computation is not a pure sequence, sequence A will be automatically converted to an ordinary sequence.

Parameter:

A	A sequence

Return value:

A sequence

Example:

	A
1	=["a","c","d","e","f"].i()	Return a pure sequence.
2	=A1.o()	Convert A1’s pure sequence to an ordinary sequence.
3	=[1,2].i()	Return a pure sequence.
4	=[3].o()	Return a pure sequence.
5	=A3&A4	Return an ordinary sequence [1,2,"3"].

P.o()

Descripiton:

Convert a pure table sequence to an ordinary sequence.

Syntax:

P.o()

Note:

The function converts pure table sequence P to an ordinary sequence.

Parameter:

P	A pure table sequence

Return value:

Table sequence

Example:

	A
1	=demo.query("select EID,NAME,GENDER,DEPT,BIRTHDAY from employee")	Return a table sequence where all fields are pure ones.
2	=A1.i()	Convert A1’s table sequence to a pure one.
3	=A2.o()	Convert A2’s pure table sequence to an ordinary table sequence.
