How to return same data in different column?

I have few columns as below:

  column1 column2 column3 column4
  ID123   Apple   Red     Apple
  ID456   Apple   Blue    Apple
  ID987   Pear    Blue    Apple
  ID899   Pear    Blue    Apple

I wanted to pull rows where column2 = column4 as below:

  column1 column2 column3 column4
  ID123   Apple   Red     Apple
  ID456   Apple   Blue    Apple

I tried:

  select column1,column2,column3,column4
  where column2=column4

But no result are returned.

Where is my mistake?

As Recommend to you if the collation is Case Sensitive then you should make the columns all the same by using either UPPER or LOWER i would also do a replace for any spaces.

Example

 CREATE TABLE #temp1
(
    column1 NVARCHAR(255),
    column2 NVARCHAR(255),
    column3  NVARCHAR(255),
    column4 NVARCHAR(255)
)

INSERT INTO #temp1 VALUES('ID123','Apple','Red',' Apple')
INSERT INTO #temp1 VALUES('ID456','Apple','Blue','Apple')
INSERT INTO #temp1 VALUES('ID987','Pear','Blue','Apple')
INSERT INTO #temp1 VALUES('ID899','Pear','Blue','Apple')

SELECT * FROM #temp1
WHERE REPLACE(UPPER(column2), ' ', '' ) = REPLACE(UPPER(column4), ' ', '' )

drop table #temp1
