Concatenate with parentheses around a column

Concatenate with parentheses around a column

Concatenate with parentheses around a column

I have a concatenation problem.  I can get the left parentheses to display but not the right.  Here is what should happen, if column 2 is populated the concatenate col1 with parens around col2.  If col2 is null then concatenate col1 with parens around a dash.  It functions properly for placing the das in the field, I'm just having trouble closing the paren.  Help is always greatly appreciated.  Please see example.


col1 || '('|| NVL(col2,'-') || ')' || as NewCol,

Result should be:
Rec    NewCol

1    Data1 (Data2)
2    Data1( - )

RE: Concatenate with parentheses around a column

If you want to write ANSI SQL, use COALESCE instead of NVL.

Your concatination seems to need a minor correction, remove the last ||, i.e.
col1 || '(' || COALESCE(col2,'-') || ')' as NewCol,
