How can I choose to show only unequal data result and minus or blind equal data result?

问题

Here's my robot code

There are 22 records on both tables but only 1 record has an unequal data I would like to show that result and minus or blind an equal data result.

 connect to database using custom params  cx_Oracle    ${DB_CONNECT_STRING}
 @{queryResultsA}=   Query  Select count (*) from QA_USER.SealTest_Security_A order by SECURITY_ID
 Log  ${queryResultsA}
 @{queryResultsB}=   Query  Select count (*) from QA_USER.SealTest_Security_B order by SECURITY_ID
 Log  ${queryResultsB}

should not contain match    ${queryResultsB}  ${queryResultsA}

1. Using For Loop

    # Assuming your table has values like this
   @{queryResultsA}=   Create List     a   b   c   d   e
   @{queryResultsB}=   Create List     a   z   c   d   e
   
   ${Length}=  Get Length      ${queryResultsA}
   ${count}=   Set Variable
   
   :FOR     ${count}   IN RANGE     ${Length}      
   \       Run Keyword If  '@{queryResultsA}[${count}]'!='@{queryResultsB}[${count}]'      Log To Console      @{queryResultsA}[${count}] @{queryResultsB}[${count}]
   

   OUTPUT
   b z

2. Using SET

   ${z} =  Evaluate    (set(${queryResultsA}) - set(${queryResultsB}))
   Log     ${z}
   

   OUTPUT
   b

   Note the difference here Set B is subtracted from Set A so whatever not matched in set A will be the output.
