Oracle SQL, concatenate multiple columns + add text
(6 answers)
Closed 7 years ago.
when I run the below query
select concat(column1,column2,column3) as concatcolumn from table
I get an error "ORA-00909:INVALID NUMBER OF ARGUMENTS"
Concat only takes two arguments.
See: http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions026.htm
Use the concatenation operator:
select column1 || column2 || column3 ...
select ([column1]+','+[column2]+','+[column3]) as concatcolumn from table
Try above the query.it may changes on different type of column data type.

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 want search a string in all 10 columns in a SQL table. How can I do it in SQL?
For example :
I have to search “Computer” word in all ten columns or all the columns in a single table .
You should use "OR" operator.
For Example:
SELECT * FROM Table
WHERE (col1 LIKE '%searchstring%') OR (col2 LIKE '%searchstring%') OR (col3 LIKE '%searchstring%')

Select from any of multiple values from a Postgres field
(3 answers)
Closed 5 years ago.
I'm new to SQL. I've got my table with 3 columns. Given a list of values (lets say ints for example 1, 4, 3) I want to select rows in which the second columns value equals something that the given list contains.
Is it possible to pass a list as an argument in SQL?
select * from TABLE1 where ...
How do i finish this statement for it to work as i explained?
I'm using PostgreSQL 9.4
Try the following query:
SELECT *
FROM TABLE1
WHERE col2 IN (1, 4, 3);
Most flavors of SQL support the IN clause, which allows comparing a column against a sequence of values. In the query above, we compare col2 against a collection of numbers, but we can equally compare against string literals, etc.

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.
