Is there an Oracle SQL query that aggregates multiple rows into one row?
Agregate rows in Oracle SQL statement
I am working with Oracle 10g. I want to have a comma separated String from a column in a table.
e.g.
Table : Customer
Columns: id and name
Data:
id-------name
1-------John
2-------Galt
3-------Howard
4-------Roark
Output of query should be Jon,Galt,Howard,Roark
Ok, got it, all I wanted was this:
SELECT WM_CONCAT(NAME) FROM CUSTOMER;
Marking all comments as +1. Thanks guys.

Referring to a Column Alias in a WHERE Clause
(9 answers)
Closed 1 year ago.
I am using a simple select statement and creating a column using a CONCAT function and labeling the column as Filter.
Why is the new column not being recognized?
Error message states
Invalid Column Name - Filter
You can't refer to column aliases in the where clause as the where is processed before the alias is materialised.
There are several workarounds, and assuming SQL Server you can do
select *
from table t
cross apply (values(concat(columna,columnb)))c([filter])
where [filter]='something'
Also note that the performance won't be great on large data sets since this criteria is non-sargable

I have a table with a field with values stored in the "STANDARD,ELITE,DELUXE" format. I want to find all the rows where this field contains a defined value, e.g. ELITE or ELITE,DELUXE.
How can I perform a query in MSSQL SERVER to search a value in a field like this one?
Any help would be highly appreciated.
Thank you,

How to view all the Metadata of columns of a table in oracle database?
(2 answers)
Closed 8 years ago.
What is the sql query to display the data types of each column in an oracle database table?
For example lets say I have a table called workflow_status with the following columns.
WORKFLOW_STATUS_ID, STATUS_NAME, LABEL, CREATED_DATE, UPDATED_DATE
What is the SQL query that will display the datatype of WORKFLOW_STATUS_ID, STATUS_NAME, LABEL, CREATED_DATE and UPDATED_DATE?
In Oracle, the DESC command is used to describe a table.
DESC workflow_status;

Possible Duplicate:
Concat all column values in sql
I have a table
ID | Name
1 | X
2 | y
3 | z
I have to show values in column Name as comma separated i.e x,y,z.
One way I can do is looping the values of column "Name" and displaying as comma separated.
Is there is a other way to do it.Please help.
Even though this is a duplicate of several other questions, I'd like to give an answer, because the easiest way to do this has changed recently. Oracle has provided the very nifty LISTAGG function with the following syntax:
SELECT
LISTAGG(name, ',') WITHIN GROUP (ORDER BY name)
FROM
my_table;
LISTAGG is available since Oracle 11.2.
