I am trying to concatenate strings in oracle.

The following is my query:

insert into dummy values('c'||to_char(10000,'99999'));

The expected result is:

c10000

But the output I get is with a space in between ‘c’ and the value 10000:

c 10000 

How to concat without spaces?

    This is not an issue with the concatenation operator but with the function to_char(). Try instead:

    to_char(10000,'FM99999')
    

    I quote the manual here:

    FM ..
    Returns a value with no leading or trailing blanks.
