Question

hello experts;
I have a query similar to this below

select '190 main st' as ID from dual
) tpI am trying to make the id field an hyperlink, so that when it is clicked on it passes the associated id into the link and navigate the user to the site, the only problem is the syntax. this is what i have done so far all
select '<A STYLE="font-size: 80%;" HREF="https://maps.google.ca/maps?q=' + ty.id   + '" TARGET="_blank"> ty.id </A>'
from tbl_test tyall help is appreciated. thank you

Hi,
The operator for concatenating strings in Oracle is || (not + ).
Also, what should the user see as the link: 'ty.id', or something like '180 main street'? If ty.id is inside single-quotes, that means literally those 5 characters. If it's outside of the single-quotes, then the value of the column ty.id is meant.
Try this:
SELECT  '<A STYLE="font-size: 80%;" HREF="https://maps.google.ca/maps?q='
     || ty.id  
     || '" TARGET="_blank"} '   -- replace }; see note below
     || ty.id
     || ' </A>'
FROM      tbl_test ty
;NOTE: This site often does strange things when you have a line with unbalanced angle-brackets. I wanted to use a &gt; symbol in place of } above, but that causes the rest of the line, and the next 2 lines, to disappear. After you copy this, change the } to a &gt;.
