I am using the function colpivot.sql (https://github.com/hnsl/colpivot) to convert rows into columns dynamically. I need to place the result of this query in a view in PostgreSQL.
CREATE OR REPLACE VIEW fun_test AS
SELECT colpivot('_test_pivoted',
'select * from _test',
array['year', 'month'],
array['country', 'state'],
'#.income', null);
SELECT * FROM _test_pivoted;
When I execute the query, it gives me the following error:
ERROR: column "colpivot" has pseudotype void
SQL state: 42P16
How can I make it work?

Hello I have created a view, but want to pivot it.
OUTPUT before pivoting:
expected output:
my full query:
SELECT *
FROM CROSSTAB(
'SELECT DISTINCT GROUP_DEST::TEXT,DEST::TEXT,TIER::TEXT,RATE::TEXT FROM VBB_TIER ORDER BY 1,2')
AS CT(ROW_NAME TEXT, TIER_1 TEXT, TIER_2 TEXT )
I getting this error and unable to resolve:
ERROR: invalid source data SQL statement
DETAIL: The provided SQL must return 3 columns: rowid, category, and values.
SQL state: 22023
Using filtered aggregation is typically a lot easier than the somewhat convoluted crosstab() function:
select group_dest,
dest,
max(rate) filter (where tier in ('0-100', ('0-150')) as tier_1,
max(rate) filter (where tier in ('101-200', '151-350') as tier_2
from vbb_tier
group by group_dest, dest;
I'm trying to return table as function value.
My code, but gives syntax error:
drop function if EXISTS fn_must_edukas;
CREATE FUNCTION fn_must_edukas()
returns Table as
return(
Select Top 1 v_mangijad.isik_nimi as mängijaNimi,(SUM(punkt)) as punktid_mustad from v_punkti join
v_mangijad on v_mangijad.isik_id=v_punkti.mangija
where varv='M'
GROUP BY mängijaNimi
order by punktid_mustad desc);
select fn_must_edukas()
Thanks!
You have one problem in the last line:
select fn_must_edukas()
It should be:
select * FROM fn_must_edukas()
Because you are returning a table.
I have a few rows stored in a source table (as defined as $schema.$sourceTable in the UPDATE query below). This table has 3 columns: TABLE_NAME, PERMISSION_TAG_COL, PT_DEPLOYED
I have an update statement stored in a string like:
var update_PT_Deploy = s"UPDATE $schema.$sourceTable SET PT_DEPLOYED = 'Y' WHERE TABLE_NAME = '$tableName';"
My source table does have rows with TABLE_NAME as $tableName (parameter) as I inserted rows into this table using another function of my program. The default value of PT_DEPLOYED when I inserted the rows was specified as NULL.
I'm trying to execute update using JDBC in the following manner:
println(update_PT_Deploy)
val preparedStatement: PreparedStatement = connection.prepareStatement(update_PT_Deploy)
val row = preparedStatement.execute()
println(row)
println("row updated in table successfully")
preparedStatement.close()
The above piece of code does not throw any exception, but when I query my table in a tool like DBeaver, the NULL value of PT_DEPLOYED does not get updated to Y.
If I execute the same query as mentioned in update_PT_Deploy inside DBeaver, the query works and the table updates. I am sure I am following the correct steps..
I would like to filter results for the same column with multiple values
example in sql:
SELECT * FROM myTable WHERE status = 1 AND current_condition = ("New", "Working")
this will return all rows from myTable where the status is 1 and the current_condition is "New" OR "Working"
how do I do this in SQLite.swift?
You can use raw SQL in Swift. So you can use the string you posted.
Raw SQL
Using Filters
I use Filters, gives me more insight.
I'm using PostgreSQL 9.1 and let's say I have a type in PostgreSQL like:
CREATE TYPE sticker AS (
customer_id integer,
customer_machine_id integer,
);
and I have a plpgsql named get_sticker that returns the type sticker...
I can do this fine:
select get_sticker(a_value), * from foo_bar;
But, this returns the result in a tuple (which totally makes sense). But, how can I convert (basically unpack) to columns?
It seems like it would be something like the following, but it fails.
select get_sticker(a_value).*, * from foo_bar; -- <<<< FAIL
Error message:
ERROR: syntax error at or near "."
SQL state: 42601
You need an extra set of parentheses:
select (get_sticker(a_value)).*, * from foo_bar;
