Reference to record

Question

Hi,
I have problem with referencing to record of table.
Could you help me, please.
I have two tables:
tab1(PK_tab1,something) and tab2(PK_tab2,FK_pk_tab1,somethingelse)
relation tab1.pk = tab2.FK_pk_tab1
On 1st page(report) is displayed by select * from tab1;Here,1st column of tab1 is PK("link"-reference to tab2 )
Now,If I click on "link" will be displayed(on 2nd page) rows from tab2(only these rows : select * from tab2 where tab1.pk = tab2.FK_pk_tab1;)
Reginons/report/1stpage/report atributes/edit column PK
I do this :
Column Formatting/Highlight Words : &P1_REPORT_SEARCH.
Tabular Form Element/Reference Table Name : tab1
..../Reference Column Name : PK
Column Link/Link Text : #PK#
.../Page : 2
Name /Value
P2_FK_pk_tab1/#FK_pk_tab1#
and in 2nd page I regions/report P2
regions definitions/source : I tried this select * from tab2 where FK_pk_tab1 = &P1_PK;
But not functional.
report error:
ORA-01008: not all variables bound
Do you know where I did wrong?

Answer 1

Try changing your query to
  select * from tab2 where FK_pk_tab1 = :P1_PKIt's best to use the bind variable format for variables in queries.
You were using the format that works like a substitution string, which is more appropriate when you want to display a variable.
Plus, you were missing the period at the end.
Variables used as substitution strings need to start with an & and end with a period.
For example:
      &P1_PK.Here's a link to that topic in the documentation:
