!1 The below functions are used internally by Slim. They should not be used in normal test cases:
* freeSymbol
* cloneSymbol

This page tests the above functions

!|Library|
|EchoScript|
|TableResultExtractor|

!3 Check that the clone $copy of a symbol $q is a real clone and not impacted by a modification of the $q
!|script| Test Query| 2|
|$q= | query|
|show | echo| $q|
|$copy= | cloneSymbol | $q|
|show | echo| $copy|
|start | Test Query | 3|
|$q= | query|
|show | echo| $q|
|show | echo| $copy|
|check| echo |$copy| [[[n, 1], [2n, 2]], [[n, 2], [2n, 4]]]|
|check |echo|$q|[[[n, 1], [2n, 2]], [[n, 2], [2n, 4]], [[n, 3], [2n, 6]]]|

!3 Free the symbol
!|script|
|check| echo |$copy| [[[n, 1], [2n, 2]], [[n, 2], [2n, 4]]]|
|check |echo|$q|[[[n, 1], [2n, 2]], [[n, 2], [2n, 4]], [[n, 3], [2n, 6]]]|
|$q= | free symbol|
|check| echo |$copy| [[[n, 1], [2n, 2]], [[n, 2], [2n, 4]]]|
|check |echo|$q|null|

!3  Get individual cell values from a query result (List<List<List<Object>>>)
!|script|
|check| echo |$copy| [[[n, 1], [2n, 2]], [[n, 2], [2n, 4]]]|
|$cell= | getValueFromQueryResultSymbol;| $copy| 0| 2n|
|check| echo |$cell|  2|
|$cell= | getValueFromQueryResultSymbol;| $copy| 1| 2n|
|check| echo |$cell|  4|
|$cell= | getValueFromQueryResultSymbol;| $copy| 1| n|
|check| echo |$cell|  2|
|$cell= | getValueFromQueryResultSymbol;| $copy| 0| n|
|check| echo |$cell|  1|

!3 Get individual cell values from a table result (List<List<Object>>)
|script|
|check| echo |$copy| [[[n, 1], [2n, 2]], [[n, 2], [2n, 4]]]|
|$cell= | getValueFromTableResultSymbol;| $copy| 0| 0|
|check | echo | $cell |[n, 1]|
|$cell= | getValueFromTableResultSymbol;| $copy| 0| 1|
|check | echo | $cell |[2n, 2]|
|$cell= | getValueFromTableResultSymbol;| $copy| 1| 0|
|check | echo | $cell |[n, 2]|
|$cell= | getValueFromTableResultSymbol;| $copy| 1| 1|
|check | echo | $cell |[2n, 4]|
|check | getValueFromTableResultSymbol;| $copy| 1| 1| [2n, 4]|



!3 Free the $copy, the $cell value must not be impacted
|script|
|$cell= | getValueFromTableResultSymbol;| $copy| 1| 1|
|$copy= | free symbol|
|check | echo | $cell |[2n, 4]|
