SQL - Remove (Eliminate) columns which have no data - sql-server

Question

I wonder that;
in SQl, is it possible to not bring the columns which have no data (or zero value)?
Select * from PLAYER_TABLE where PLAYER_NAME='cagri'
it is bringing just 1 row. because there is only one player which PLAYER_NAME is "cagri".
And there are 30 columns for example statistics.
Score-Rebound-PlayedMinutes-Fauls etc....
Score=2
Rebound=0
PlayedMinutes=2
Fauls=0
and I want to see only [Score] and [PlayedMinutes] columns when call my query.
is it possible?

You can use this logic over a stored procedure in SQL
DDL
create table usr_testtable
(player varchar(30),col1 float, col2 float, col3 float, col4 float)
insert into usr_testtable
values ('Jordan',10,20,3,0)
Convert to Stored Proc
declare #playername varchar(30) = 'Jordan' --- pass this value
declare #ctr smallint = 2 -- start from ordinal 2
declare #maxctr smallint = (SELECT max(ORDINAL_POSITION)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'usr_testTable')
declare #columns varchar(max) = ''
declare #columnswithvalues varchar(max) = ''
declare #coltocheck varchar(30)
declare #mysql nvarchar(max)
declare #coloutput varchar(30)
while #ctr <= #maxctr
begin
SELECT #coltocheck = COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'usr_testTable'
and ORDINAL_POSITION = #ctr
set #mysql = N'select #output = ' + #coltocheck + ' from usr_testTable where player =''' + #playername + ''' and cast(' + #coltocheck +' as float) > 0'
EXECUTE sp_executesql #mysql,N'#output int OUTPUT',#output = #coloutput OUTPUT;
if #coloutput > 0
begin
set #columns = coalesce(#columns + ',' + #coltocheck,#columns)
set #columnswithvalues = coalesce(#columnswithvalues + char(13) + char(10) + #coltocheck + ' : ' + #coloutput,#columnswithvalues) --- text form
end
set #coloutput = ''
set #ctr= #ctr + 1
end
-- final result in table format
set #mysql = N'select player' + #columns + ' from usr_testTable where player =''' + #playername + ''' '
EXECUTE sp_executesql #mysql
-- final result in text format appended with columnname
select #columnswithvalues -- format to display in text

First create dynamic SQL to select all columns names in the table PLAYER_TABLE except PLAYER_NAME, then unpivot data from PLAYER_TABLE into table PLAYER_TABLE1, then you can search values <> 0 and select this column in second dynamic SQL.
DROP TABLE PLAYER_TABLE1
DECLARE #Player NVARCHAR(50);
DECLARE #columns NVARCHAR(max);
DECLARE #sql NVARCHAR(max);
DECLARE #columns2 NVARCHAR(max);
DECLARE #sql2 NVARCHAR(max);
SET #player='cagri'
SET #columns = Stuff((SELECT ','
+ Quotename(Rtrim(Ltrim(x.columns)))
FROM (SELECT COLUMN_NAME as columns FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME= 'PLAYER_TABLE' and COLUMN_NAME<>'PLAYER_NAME' ) AS x
ORDER BY X.columns
FOR xml path('')), 1, 1, '');
SET #sql = N' SELECT
PLAYER_NAME, Un_Pivot.Field, Un_Pivot.Value
INTO PLAYER_TABLE1
FROM
(
SELECT * FROM PLAYER_TABLE
) Data
UNPIVOT
(
Value FOR Field IN ('+#columns+')
) AS Un_Pivot';
EXECUTE sp_executesql #sql;
SET #columns2 = Stuff((SELECT ','
+ Quotename(Rtrim(Ltrim(y.Field)))
FROM (SELECT Field FROM PLAYER_TABLE1 WHERE VALUE<>0 AND PLAYER_NAME=#Player) AS y
ORDER BY y.Field
FOR xml path('')), 1, 1, '');
SET #sql2 = N'SELECT PLAYER_NAME,'+#columns2+'FROM PLAYER_TABLE WHERE PLAYER_NAME='+char(39)+#Player+char(39);
EXECUTE sp_executesql #sql2
