I need to write a sql for a prompt in a reporting tool. I get the list of multiple values in a variable separated by '-' and the number of such values can vary.(eg1."abc-def" eg2."abc-def-xyz").
Now I need to write sql in oracle of this form(logically)
select something
from somewhere
where someColumn in 'abc' -- use substr to extract abc
or someColumn in 'def' -- use substr to extract def
or ...till we don't find '-'.
I can't use plsql for the query. Either I may not be knowing to use the variable in which I select into in plsql or may be the reporting tool doesn't support that.
Thanks in advance.
Try
select something
from somewhere
where someColumn in (select regexp_substr('abc-def-xyz','[^-]+', 1, level) from dual
connect by regexp_substr('abc-def-xyz', '[^-]+', 1, level) is not null);
To generalize (considering your fields are separated by "-")
select something
from somewhere
where someColumn in (select regexp_substr(variable,'[^-]+', 1, level) from dual
connect by regexp_substr(variable, '[^-]+', 1, level) is not null);
Basically the output of the subquery is shown below -
SQL> select regexp_substr('abc-def-xyz','[^-]+', 1, level) value from dual
connect by regexp_substr('abc-def-xyz', '[^-]+', 1, level) is not null;
VALUE
--------------------------------
abc
def
xyz
First split the string into its parts using Oracle's regexp_substr() function. See regexp_substr function (If you can access the original that generates the string, just use that.)
Second, put this in a temp table and then just have:
select something
from somewhere
where someColumn in (select parts from tmpTable)
select something
from somewhere
where INSTR('-'||'abc-def-ghi'||'-', '-'||someColumn||'-') > 0;
If you just want a list of results that contain a '-', you could just do something like
SELECT SOMETHING FROM SOMEWHERE WHERE SOMECOLUMN LIKE ('%-%');
