Hello-

I have a table, DEV_QRY_QC_HCC_131. It has two columns qry_id and hic_number (a member ID). The table has 12,702 records. There are 16 distinct qry_id values (e.g. qry_1,qry_2,etc...) and 7,090 distinct hic_number values (e.g. 123456789A, 987654321A, 456789123B, etc...)

I would like to create a subset table with two columns qry_id_2combo and hic_number, in which qry_id_2combo is two distinct qry_id values, like this:

qry_id_2combo hic_number
qry_1&2 123456789A
qry_1&2 987654321A
qry_1&3 456789123B

I'm thinking I'll need to use cursors and loops, which really isn't TSQL is it? It's PL/SQL...

Do you mean that out of the 16 qry_id values in the table, you just want rows that match two of those qry_id values.

e.g. For table DEV_QRY_QC_HCC_131 containing these rows, you only want to select out where qry_id is 1 or 3 for example?

qry_id hic_number
1 1234546
1 435676756A
2 764321343
3 794674hkf
4 213126786638712


giving these results:

qry_id hic_number
1 1234546
1 435676756A
3 794674hkf

No, I'm looking for two-way qry_id combinations, by hic_number....

SELECT MIN(qry_id), MAX(qry_id), hic_number
FROM Table1
GROUP BY hic_number
HAVING COUNT(*) = 2

Can you post the ddl and some sample data that would provide us the background for what you're looking to generate:

qry_id_2combo hic_number
qry_1&2 123456789A
qry_1&2 987654321A
qry_1&3 456789123B


We're guessing as to what the source data looks like exactly and that's not helping. See the first link in my sig if you'd like some assistance with that.

qry_1&2 123456789A
qry_1&2 987654321A

We're guessing as to what the source data looks like exactly and that's not helping. See the first link in my sig if you'd like some assistance with that.




Sample starting data:
hic_number qry_id
00005A 9130813
00005A 9130850
00010A 9130813
00010A 9130850
00010A 915216
00010A 915416
00021A 9130813
00021A 9130850


The end result of this sample would be:
hic_number qry_2combo_id
00005A 9130813+9130850
00010A 9130813+9130850
00010A 9130813+915216
00010A 9130813+915416
00010A 9130850+915216
00010A 9130850+915416
00010A 915216+915416
00021A 9130813+9130850
