I have above two table.I want to display third table using oracle. I know display those data using java,vector and other stuff.But couldn't code correct oracle code.In the above display table shows data which are >=SYSDATE.
I think it is something like this:
select e.event_name,
min(dt.start_date) as start_date,
min(dt.start_date)||'-'||max(dt.end_date) as FromTo
from event e join
date_table dt
on e.e_id = dt.e_id
group by e.event_name;
You may need use to_char() to convert date/times to the right format. You don't specify wht the types are in the data, so it is hard to say what needs conversion.

I'm writing the following SQL query:
SELECT *
FROM OS
WHERE OS.VERSION LIKE '%1%';
In my table there are rows with char 1 in it. However, it returns an empty result.
I changed a little bit the LIKE clause to different values, but it still doesn't work.
What can I do to fix that?
Try double-quotes and * for wildcards. You are using Oracle syntax instead of Access syntax.
LIKE operation can't be used with columns of integer type. I assume that OS.Version is of integer type?
Edit1:
If you are referring to MS Access then you have to do the LIKE with stars (*) instead of %.

I have a string like this:
i would like to go to office, and i would like to go to market
My question is: how many times the word like occurs in the string?
Please write a query.
You can use regexp_count:
SELECT REGEXP_COUNT('i like to go , and i would like market', 'like')
FROM DUAL;
The word "like" occurs twice in the string you posted.
The following is a query:
SELECT *
FROM SOME_TABLE
WHERE SOME_VALUE = SOME_OTHER_VALUE
Share and enjoy.

I am writing a macro which pulls data from Oracle and displays in Excel. In Oracle DB we have a custom table with a column Named "Calculated_Quantity". The datatype of this column is BINARY_DOUBLE.
When I query for this column in Oracle using SQL developer I am able to view the data. However when I write the same query in Excel macro, I get the error as "Data Type is not Supported".
Any suggestions what do I need to do here. If needed I can post my query here.
Thanks,
You should use CAST (or CONVERT for some DBMSs) to convert the data to a supported datatype.
SELECT
CAST(CALCULATED_QUANTITY AS NUMBER(10)) AS Qty
FROM
DW_STG_FSN.SAMPLE

I am executing this query in SQL Server 2008
SELECT (CONVERT(DATE, GETDATE()))
and it shows the result 2013-07-22.
I need to print this result as 22713, where 22 is the date 7 is the month 13 is the year.
How could I do this?
SELECT CAST(DATEPART(dd,GETDATE()) as varchar(10))
+CAST(DATEPART(mm,GETDATE()) as varchar(10))
+RIGHT(CAST(DATEPART(YY,GETDATE()) as varchar(10)),2)

1) It bad practice use SQL for string operation. More right external tools
2) I use other RDBMS. Below query work with it:
select (extract(day from ua.stamp))||(extract(month from
ua.stamp))||(extract(year from ua.stamp)) from useractions ua
Furthemote, this link can help you:

You could read the string, go over it with a tokenizer, split it and put it back together the way you want it to be. What language are you using?

I am having two table A and B of same structure.Both tables is loaded with data.I just want the mismatched row of two tables.,,
I'm certain you could do some gigantic JOIN query for each column and then issue a NOT IN over the result but a simple, pragmatic solution is to:
Write a query that orders the data on several columns (or all)
Export the query executed on each table to a separate text file
Use diff to compare the files with each other
Depending on the RDBMS vendor you may have other options you could consider as well.
