I have Table A with columns CompetenceId, Description and Development Action. This is Table A

I have another table B with CompetencyId and Development Action.

As each CompetenceID is having multiple development actions in table B. My requirement is for 'Table A' I need 'Development action' column for a particular competencyId in the same row up on joining Table B. The result should look like below for Table A

How can I achieve this? Thanks in advance
