Insert Columns Into Table Based On Condition?

My requirement is below.enhancing the T- sql query as I was told not to use SSIS.

Insert data from Table A to Table B with conditions:

1. Truncate gender to one character if necessary.

2. Convert character fields to uppercase as necessary.

3. For systems that supply both residential and mailing addresses, use the residential address if available (both street_address and zip fields have value), mailing address otherwise.

In SSIS I took conditional split with 'ISNULL(res_street_address) == TRUE || ISNULL(res_zip) == TRUE '

default outputname :Consider Res Address; Outputname:Consider mail address.

and mapped as:

(Table A) mail_street_address---street address(Table B)

(Table A) mail_city----------------City(Table B)

(Table A) mail_Zip----------------Zip(Table B)

(Table A) mail_state-------------state(Table B)

(Table A) res_street_address--street address(Table B)

(Table A) res_city---------------City(Table B)

(Table A) res_Zip----------------Zip(Table B)

(Table A) res_state--------------state(Table B)

I want to do the same with T-sql code too:

I came up with below T-SQl but unable to pick(street,city,state,zip columns as I have take combination of street and zip from Table A not individual columns as I wrote in below query) based on above condition(3):

Insert into TABLE B
SELECT
Stats_ID
,UPPER(first_name) first_name
,UPPER(middle_name )middle_name
,UPPER(last_name) last_name
,UPPER(name_suffix) name_suffix

[code]....
