I am using PostgreSQL 10 and pgAdmin-4 for learning postgreql. I am using the Sakila database.
My question is how do I select/call stored function correctly?
I tried out one stored function on the Sakila database,
SELECT inventory_in_stock(10)
without any problem.
However when I tried another,
SELECT get_customer_balance (3,NOW());
I get the following error:
ERROR: function get_customer_balance(integer, timestamp with time zone) does not exist
LINE 1: SELECT get_customer_balance(3,NOW());
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
SQL state: 42883

When I try and enable compression on my TimeScale DB hypertable using this query:
ALTER TABLE public."Session" SET (
timescaledb.compress,
timescaledb.compress_segmentby = 'AssetId'
);
I get the following error:
ERROR: column "assetid" does not exist
HINT: The timescaledb.compress_segmentby option must reference a valid column.
SQL state: 42601
All I can say is that AssetId is a valid column in the Session table. I'm not sure what else to try.
Is anybody familiar with this error and could offer a solution please?
Thank you
Sometimes Postgresql requires the case-sensitive version of the name and therefore the column name was to be quoted.
That said, all you do is to double-quote the name inside the passed string:
timescaledb.compress_segmentby = '"AssetId"'
I tried to query data in TDengine with the following sql clause:
SELECT * from TABLE where COLUMN < FUNCTION();
and I got illegal condition expression error.
Does anyone know if using function in where condition is illegal usage in SQL convention or I need to resort to other syntax?
Using function in where condition is illegal. Maybe it will be supported later.
I'm trying to execute the below statement on PostgreSQL 12.4. This statement was converted from Oracle 10g to PostgreSQL 12.4 using the online SQL Lines tool.
select
hid,
pname,
starting_from,
ename
from schema1.pet
where hid=COALESCE(TO_NUMBER(sys_context('temp1','hid')),0);
I'm getting the below error:
ERROR: function sys_context(unknown, unknown) does not exist
LINE 7: where hid=COALESCE(TO_NUMBER(sys_context('temp1','hid...
I'm not sure what's the equivalent of sys_context in PostgreSQL.
How can I fix this statement to PostgreSQL?
The PostgreSQL current_setting() function comes closest to the Oracle sys_context() function. PostgreSQL does not use the namespace parameter, however.
I am using PostgreSQL database and there is a field in a table(area) i.e. geog pulic.geography(Points,4326). It contains below type of records
0101000020E6100000BA83D89942334540780B24287ED051C0
I am using ST_AsGeoJson(), to get the GeoJson through above types of records.
My database is connected and I am using a query to fetch result i.e.
$query="SELECT ST_AsGeoJSON(geog) FROM area";
But I am getting below warning and not getting any results
Warning: pg_query(): Query failed: ERROR: function
st_asgeojson(public.geography) does not exist LINE 1: SELECT
ST_AsGeoJSON(geog) FROM public.area ^ HINT: No function matches the
given name and argument types. You might need to add explicit type
casts. in /home/domain/public_html/sg_database.php on line 20"
Please suggest regarding this..
Thanks
My boss sent me a process, in to which I need to:
make a function that creates a temp table
grab data from a table
use a function to refine the data
create a hash code for 2 of the columns
insert all the data from the temp to the original data
drop the table
I've been trying to look what the make_hash() function does. Whenever I run the FUNCTION it gives me an error on that line, so I'm guessing I need to declare it first before the begin statement in the create function. Or is it a user-created function? If so, is there a way for me to find which schema the function is located?
I've been trying to research in the books and online but I couldn't find anything, even in the PostgreSQL website.

As #Clodoaldo mentioned look into pgcrypto (which you would get by installing it to your postgres, on debian its in postgresql-contrib iirc).
Any function you call must be available before the BEGIN section. You can combine functions into packages if you need more than one.
Nevermind! The make_hash function was written psql that's why it wasn't working properly. I'm using pgAdmin III and the schema name had to be called together with the function for it to work. Thanks a bunch for the help though!
