vertical serches on a table - how to
Hi, I have a table that I would like to perform a vertical search on. For eg. Table X --- IDCOL1 COL2 1 apple orange 1 mango banana 1 grape pineapple 2 mango banana 2 guava lemon I would like to display records that meet the following criteria for *a particular ID*. (COL1=banana) OR (COL1=mango and COL2=banana AND COL1=grape and COL2=pineapple The output should be ID COL1COL2 1mango banana 1grapepineapple It should not display ID COL1COL2 2mango banana since ID=2 did not meet the criteria where COL1=grape and COL2=pineapple. I tried the following SQL but the output is always zero because COL1 can never be a mango and a grape and COL2 can never be a banana and a pineapple at the same time for a particular ID. select ID, col1, col2 from tableX where (col1='banana') or ((col1='mango' and col2='banana') and (col1='grape' and col2='pineapple') ); Any idea how I can do a vertical search on the table.

Stephane, Apologize for not being clear on my question. The query you have provided will only return one record, ie. 1 mango banana. I need two records to be returned: 1 mangobanana 1 grape pineapple You're right that by 'vertical', I meant filtering according to conditions on OTHER rows but at the same time, I want those filter conditions to be displayed as well, which in this case - grape and pineapple. Any idea.

Thanks for any help you can provide. susan Susan, Took me some time to understand what you meant by 'vertical search'. ANDs and ORs in a WHERE clause always apply to the current row under scrutiny. What you mean by 'vertical' is that you want to filter according to conditions on OTHER rows. This is done by a subquery. Your query could read select X1.ID, X1.col1, X1.col2 fromtableX X1 where (X1.col1='banana') or ((X1.col1='mango' and X1.col2='banana') and EXISTS (select null from tableX X2 where X2.col1='grape' and X2.col2='pineapple' and X2.ID = X1.ID)); Simplifying to the extreme, each different row you handle must be returned by its 'own' query.

Stephane, Fantastic! Appreciate the help.

Any idea. Thanks. susan In that case you keep something looking vaguely like the condition in your initial query but add a subquery to check that both conditions are satisfied : select X1.ID, X1.col1, X1.col2 from tableX X1 where (X1.col1='banana') or (((X1.col1='mango' and X1.col2='banana') or (X1.col1='grape' and X1.col2='pineapple')) and 2 = (select count(*) from tableX X2 where ((X2.col1='mango' and X2.col2='banana') or (X2.col1='grape' and X2.col2='pineapple')) and X2.ID = X1.ID))); No guarantee on the proper number of parentheses.
