Hi Team,
I have the below data in a column called as "DATA" in oracle.I was trying to remove the new empty line after each line .
Input :
This is a text from line 1.
This is text from line 2.
This is a text from line 3.The line 3 ends here .
This is a text from line 4.The line ends here .
output :=
This is a text from line 1.
This is text from line 2.
This is a text from line 3.The line 3 ends here .
This is a text from line 4.The line ends here .
I have tried using
Query :
Select regexp_replace(regexp_replace(data,chr(13),null),chr(10),null) from main_data;
When i execute the below query the output is like a paragraph .
Query Output:
This is a text from line 1.This is text from line 2.This is a text from line .The line 3 ends here .This is a text from line 4.The line ends here .
Can any one say how to achieve this ?
Thank you.

End Of Line markers are just that - every line has them, not just blank ones.
Your data is really
This is a text from line 1.chr(10)
chr(10)
This is text from line 2.chr(10)
chr(10)
This is a text from line 3.The line 3 ends here .chr(10)
chr(10)
This is a text from line 4.The line ends here .
If you replace every EOL with null then you get a single line.
To get rid of blank lines you need to replace two consecutive EOLs with a single EOL.
So either replace chr(10)||chr(10) with chr(10)
or replace chr(13)||chr(10)||chr(13)||chr(10) with chr(13)||chr(10)
depending on whether you have unix or dos line endings.

Just for fun without regular expressions and assuming CHR(0) can't appear in text:
with data as (
select 'This is a text from line 1.
This is text from line 2.
This is a text from line 3.The line 3 ends here .
This is a text from line 4.The line ends here .
' val from dual )
select replace(replace(replace(val,chr(10),chr(10) || chr(0)),chr(0) || chr(10)),chr(0)) val
from data
/
VAL
--------------------------------------------------
This is a text from line 1.
This is text from line 2.
This is a text from line 3.The line 3 ends here .
This is a text from line 4.The line ends here .
