Sorry-duplicate thread,since problem in forumby5.45pm pl/sql region in apex

Question

Hi All,
From sqlworkshop,
I have created a view like
CREATE OR REPLACE FORCE VIEW VW_SUB_CL_ADD1 AS
(select a.siteid siteid,a.bpaadd_0 bpaadd_0,a.bpanum_0 bpanum_0,
case when a.bpaaddlig_0 = '' then '-' else a.bpaaddlig_0 end address1,
case when a.bpaaddlig_1 = '' then '-' else a.bpaaddlig_1 end address2,
case when a.bpaaddlig_2 = '' then '-' else a.bpaaddlig_2 end address3,
case when a.bpades_0 = '' then '-' else a.bpades_0 end place,
case when a.cty_0 = '' then '-' else a.cty_0 end city,
case when a.poscod_0 = '' then '-' else a.poscod_0 end pincode,
case when b.cntnam_0 = '' then '-' else b.cntnam_0 end contactname,
case when b.fax_0 = '' then '-' else b.fax_0 end fax,
case when b.MOBTEL_0 = '' then '-' else b.MOBTEL_0 end mobile,
case when b.TEL_0 = '' then '-' else b.TEL_0 end phone,
case when b.web_0 = '' then '-' else b.web_0 end website,
c.zinvcty_0 zcity,c.bpainv_0 bpainv_0,c.bpcnum_0 bpcnum_0
from lbcreport.bpaddress@info a,lbcreport.contact@info b ,lbcreport.bpcustomer@info c
where (a.bpanum_0=b.bpanum_0) and (a.cty_0 = c.zinvcty_0) and (a.siteid = c.siteid))
but when i execute select * from vw_sub_cl_add1
the case is not working. '-' is not getting displayed for null values even i tried nvl function it is not working
when i use this view in apex for pl/sql region to display in the form of table .
The problem is, when there is no value in the columns the table is not showing row and column in a proper manner.
could any one help to overcome it.
Thanks in advance
bye

Answer 1

Srikavi,
1. The problem with null values is a template problem. Using Firefox and Web Developer Toolbar extension / CSS / View Style Information, you can find out which css class your report is referencing. Open the corresponding css file and add the following to the css class:
empty-cells:show;border-collapse:collapse;
It will show the borders for null values after that.
2. b.fax_0 = '' is not correct. It should be b.fax_0 IS NULL.
3. You can also try to use the built in property for showing NULL values as in the report attributes.
