I would like ask if this is possible in any database. Lets say there's one column on my database that has a content like this:
-----------------
|columname |
-----------------
| roan,joan,keith|
------------------
If I do a select query, can I just display roan from that field?
Thanks,
MSSQL version of Mark answer:
SELECT SUBSTRING(columnname, 1, CHARINDEX(',', columnname, 1) - 1) FROM testtable;
Oracle solution:
select substr(columnname,1,instr(columnname,',')-1) from testtable;

SQL Server creating table error.
How to give system date, system date + 2 days while creating a table?
Is the system date the same as the current date?
You can try the SQL DEFAULT Constraint as shown below if I understood your question properly:
Create table Test(id int
, name varchar(20)
, dtDate datetime default DateAdd(dd, 2, getdate()))
insert into Test (id, name) values
(1, 'A')
select * from Test

I have a column-based table like this:
And I need to convert it to a row-based table like this:
Any help would be appreciated.
I think you need an UNPIVOT -
SELECT OrgID, Property, DataValue
FROM (SELECT OrgID, Property, DataValue
FROM YOUR_TABLE
UNPIVOT
(
DataValue FOR Property IN (ExtensionDigits
,StartExtension
,LastUsedExtension
,Server1IP
,Server2IP
,ServerPort
,IsFunctionOn
,VolumeDecibel)
) unpvt) temp
WHERE DataValue IS NOT NULL;
