Extract vales from a column

Hi Experts,
I would like to extract values from  Col_2 can be used in the Where clause with IN  parameter.

Like this one: Select * from XYZ where (Select Col_1 From AAA Where Col_2 IN ('1960', '1961');

Below is the sample table.

Create Table AAA (
Col_1        Number,
Col_2        Varchar2(100));


Insert into AAA Values (1, '1960, 1961');

Insert into AAA Values (2, '');

Insert into AAA Values (3, '1970');

Insert into AAA Values (4, '1970, 1972');

Insert into AAA Values (5, '1970, 1972, 1976, 1950');

Commit;

     COL_1 COL_2
---------- -----------------------
         1 1960, 1961
         2
         3 1970
         4 1970, 1972
         5 1970, 1972, 1976, 1950

I believe you should invert the parameters
instr(C1_REC.Birth_Year,To_Char(N.NDVDL_BIRTH_YEAR))

Walter RitzelSenior Software EngineerCommented:
this should work:
with query_1 as (SELECT
AAA.col_1
,REGEXP_SUBSTR(aaa.col_2,'[^,]+', 1, LEVEL) AS KEYWORD
FROM aaa
CONNECT BY
level <= REGEXP_count(aaa.col_2,',') + 1
and prior aaa.col_1 = aaa.col_1
and prior sys_guid() is not null)
Select * from XYZ where (Select Col_1 From query_1 Where keyword IN ('1960', '1961'))

>>Select * from XYZ where (Select Col_1 From AAA Where Col_2 IN ('1960', '1961');<<
That syntax will not work. You would have to say "where exists ..." or "where some column in ..." Perhaps you can provide sample data for both tables AAA and XYZ with your expected output and the criteria used for it.

Hi Walter, I posted my reply but it did not up load. I will have to do it chunks.

Here is the part of the procedure where I want to implement your solotion.

Ok, so what you need to do is to apply my query on your source table, then you can compare with the table that have the search terms.
Please try that and let me know where you find any issues.

Just like your previous questions:  Small sample data and expected results help a lot.

You provided sample data for one table but not the other table and expected results.

Would a simple INSTR work?

Looking into your code, I cannot identify which table or cursor will have the birth years in one row (1952,1960,1975) and the table that will have one per row. Could you please point that out?

Hi walter,

Thanks for the quick reply.

The cursor C1_CUR (B.Birth_Year) has the values, like this:

BIRTH_YEAR
 ---------------
 1947,1952
 1947,1952
 1947,1952
 1947,1952
 1947,1952
 1947,1952

The table against which the vales are to be matched (SBJT) have values like,

SRCH_TERM_ID            BIRTH_YEAR
 ------------                      ------------------
           11                       1947
            11                     1952
           12                      1947
            12                     1952
           18                       1947
            18                      1952
     etc....

I think regular expressions would be overkill here.  It is a very expensive function call to make.

Try INSTR:

...
AND INSTR(To_Char(N.NDVDL_BIRTH_YEAR),C1_REC.Birth_Year) > 0
...

Walter RitzelSenior Software EngineerCommented:
I agree with slightvw. Considering how your code is structured, if you use INSTR that will suffice.
So, the following line:
AND To_Char(N.NDVDL_BIRTH_YEAR) IN C1_REC.Birth_Year

Open in new window

would be replaced by:
AND INSTR(To_Char(N.NDVDL_BIRTH_YEAR),C1_REC.Birth_Year) > 0

Open in new window

Hi experts due to lack of valid data on tables in question, I have not been able to test the modifications you suggested. I am in th eprocess of creating test data to ensure there are no hickups. I have a question. How will you describe the line below in plain english.

AND INSTR(To_Char(N.NDVDL_BIRTH_YEAR),C1_REC.Birth_Year) > 0

The INSTR funstion, looks for substring in a string and returns the nth occurance of the substring.

I have learned a lot for the Experts at Experts exchange and like to continue doing that.

slightwv (䄆 Netminder) Commented:
>>How will you describe the line below in plain english.


I don't know that I can do any better than you already did.

It looks for the occurrence of one string in another string.  Which occurrence and starting position is optional and defaults to 1.

The online docs typically have good examples and explanations:
http://docs.oracle.com/cd/E11882_01/server.112/e41084/functions080.htm#SQLRF00651

Create simple test cases to see things in action:
select instr('12345a7890a123','a') from dual;
select instr('12345a7890a123','a',1,2) from dual;

First one:
What position is the first 'a' in the string?
Next:
What position is the 'a' starting at position 1 and looking for the second occurrence.

Hi Experts,

I made the suggested change as below.

AND INSTR(To_Char(N.NDVDL_BIRTH_YEAR),C1_REC.Birth_Year) > 0

What I am seeing is that if C1_REC.Birth_Year has one value, like 1943, the procedure wooks. If C1_REC.Birth_Year has more than one value, like 1943, 1945 then the procedure does not work.
Data type of Birth_Year column is varchar2 (500 Char)
Data type of  NDVDL_BIRTH_YEAR column is Number (4).

Please advise.

Thanks a lot.

slightwv (䄆 Netminder) Commented:
Sorry.  Had it backwards.

When in doubt, set up a small test case and try things out:
drop table tab1 purge;
create table tab1( birth_year varchar2(500 char));

insert into tab1 values('1900, 1901, 1943, 1955');
insert into tab1 values('2000, 2001, 2043, 2055');
commit;


select birth_year, instr(birth_year,'1943') from tab1;
