SQL Between Query....Urgent Please Help ..

Question

Hi,
Can any one solve my problem.
Iam having two numaric columns in my database table. I like to retrive
them in the specific range.
The Example Table is.
Table Name is : SR_Table
testDate(numeric) testTime(numeric)
1 1
1 2
1 3
1 4
1 5
1 6
2 1
2 2
2 3
2 4
Infact i like to get the records between testDate = 1 and testTime = 2
and testDate = 2 and testTime = 3
Iam using the sql query as:
select * from SR_Table where testdate between '1' and '2' and testtime between '2' and '4'..
instead of giving 9 records its just giving 6 records ... it maight me a mistake in my query. the output for the above query is:
testDate(numeric) testTime(numeric)
1 2
1 3
1 4
2 2
2 3
2 4
The records
1 5
1 6
2 1 are missing...
infact iam expecting 9 records as
testDate(numeric) testTime(numeric)
1 2
1 3
1 4
1 5
1 6
2 1
2 2
2 3
2 4
Please solve my problem for using BETWEEN together in two coloumns.
Thanks,

Looks like there's a few ways to approach this, depending on your data.
If you are truly wanting values between a given range, and you have a different range for each column, then modifying your query as suggested by DrClap should work properly.select * from SR_Table
where (testdate > 0 and testdate < 3)
and (testtime > 1 and testtime < 5)
// > 0 and < 3 means 1 or 2
// > 1 and < 5 means 2, 3, or 4Looking at your example again, however, it appears that you are wanting both values together to act as a single key. Your example data would then contain the values 11 - 16 and 21 - 24.
If this is the case, then you're going to have to get a little more complicated, and implementation may depend on the database that you are using.
If your sample data is representative of your real data (nothing but INT values) then it won't be too bad (this is an Oracle implementation):select [other_fields], TO_NUMBER(testdate || testtime) as test
from SR_Table
where test > 11 and test < 17 and test > 20 and test < 25If your data is more complex, then the query becomes more complex and we'll really need to know exactly what you're trying to do.
