Calling stored procedure from a column in report

Question

Hi All,
I am new to APEX. I did a search on this forum but couldnt get an exact answer.
I know how to call or execute a stored procedure from a button. like create a PL/SQL anonymous bloack and asssociate it with the button.
my issue is a bit different. I have a report with 11 columns. the last column just says 'delete' for all the rows(i did this in my report query like SELECT x,y,z,...., 'delete' AS delete). when i click this cell for any row(this column can be a hyperlink or any clickable element), i want to call a stored procedure that takes parameters as the values in column 2 and column 4 for that particular row.
for example, my report looks somethnig like below,
FILE_ID MEMBER_CD ACTION
112 ABCD delete
113 WXYYZ delete
114 PQRS delete
i want to click the 'delete' in first row that should call a stored procedure and pass 112 and ABCD as parameters to the procedure.
i have the procedure as a process now. sturggling to bind this column to procedure but no success :(
Hope am clear. Please any help is appreciated.
Thanks

Answer 1

Thanks man! that was a great help. looks like i am almost there. i created those items t obe hidden.
now i am passing three parameters to the procedure. my url for that column value looks like this,
javascript:P65_PARTITION_ID=#PARTITION_ID#;P65_DBC=#DBC#;P65_FILE_ID=#FILE_ID#;doSubmit('Sku_Save');
the #DBC# parameter is a name of the person that has spaces(firstname lastname). i am getting a javascript error saying,
Line: 1
Char: 37
Error:Expected ';'
i see that char 37 is the space after firstname.
any idea how i should get rid of this error.
Also, as you have been very helpful, a question further beyond :). the above procedure will return a OUT varchar parameter. i guess i have to create another item for that. how do i read it and display just below my report as text.
Thanks Again!
