How to fix 'Column Reference X is ambiguous' error in postgresql..? - postgresql-9.6

I'm trying to join some tables in my database, but I found error..
I using Postgresql-9.6
SELECT
customer_id
, (select identity_card_number from basic_customer bc where bc.customer_id = ba.customer_id ) as identitu_card_number
, (select fullname from customer_pedal cp where cp.customer_id = ba.customer_id ) as fullname
, customer_id
, category_code
, (select is_cif_active_desc from basic_customer bc where bc.customer_id = ba.customer_id ) as is_active
, ba.account_number
, opening_date
, closure_date
, currency_code
, (SELECT balance_date FROM basic_balance bb where bb.account_number = ba.account_number ) as balance_date
, (SELECT balance_amount FROM basic_balance bb where bb.account_number = ba.account_number ) as balance_amount
, (select description from customer_pedal cp where cp.customer_id = ba.customer_id ) as description
FROM basic_account ba
INNER JOIN customer_pedal cp on cp.customer_id = ba.customer_id
WHERE ba.customer_id is not null;
I expected data where contain only customer id from basic_account and customer_pedal.
Here is the structure tables

I used that stored procedure in SSRS report. When I clicked on the dataset option of the report and refresh the data set, it gave following error:
I looked at the forum and found that error comes due to two or more columns have same name. I looked at the code and made sure that no column have same name. However, the problem still exist. Could anyone help me where I am making the mistake?
You have two columns both called AccountID being returned from your query
...
rntAcc.AccountId,
rntAcc.AccountReference,
rntAcc.PaymentReference,
rt.TransactionId,
rt.AccountId,
....
Alias or remove one of these columns.

Querying two partitions from same table in Bigquery

I am looking to do some querying on two partitions (different partition date) on BQ.
Table format is the following
crm_id, attribute#1, attribute#2,attribute#3
For the IDs that are common from week 1 and week 2, I want to see how many changed attribute#1, attribute#2 and attribute# 3
I started with the inner join using:
WITH t1 AS
(SELECT crm_id AS w1_crm
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date1"
)
SELECT crm_id
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date2"
INNER JOIN
t1
ON
w1_crm = crm_id
I am getting an error on the INNER JOIN
Try below
WITH t1 AS (
SELECT crm_id AS w1_crm
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date1"
), t2 AS (
SELECT crm_id
FROM `table`
WHERE DATE(_PARTITIONTIME) = "date2"
)
SELECT crm_id
FROM t2
INNER JOIN t1
ON w1_crm = crm_id

Join subqueries serval times

I have code that run:
How can I join another query in this subqueries?
I whant a third table that joins with the other tables.
How can I achive this?
select *
from
( select irart, fiben1 as "Benämning", fisald +irbant as "disp.saldo", sum(irbant) as "Lev.Best"
from triir00
left join trafi00
on irart = fiart and irfili = fifili
where IRSTYP between 00 and 02 and irlev = '2602688' and irfili = 10 and fihugr = 5
group by irart,fiben1,irlev,fisald,irbant
) as antalLev
full join
( select raart, fiben1 as "Benämning", raorn9 as "Ordernummer", fisald- raanta as "Disp.Saldo", sum(raanta) as "Kund.Best"
from trora00
left outer join trohu00
on huorn9 = raorn9
left join trafi00
on raart = fiart and rafili = fifili
where rastyp <= 02 and rafili <> 0 and raotyp = 1 and ralev1 = '2602688' and fihugr = 5
group by raart,fiben1,raorn9,fisald,raanta
) as antalBest
on antalLev.irart = antalBest.raart
Wrap your original query into brackets:
select *
from
(
-- your original query follows below
select *
from
(
select columns_for_outer_join, other_columns
from ...
) as antalLev
full join
(
select columns_for_outer_join, other_columns
from ...
) as antalBest on antalLev.irart = antalBest.raart
-- end of your original query
) a
join (
-- your another sub-query comes here
select columns_for_outer_join, other_columns
from ...
-- end of your another sub-query
) b on <a.columns_for_outer_join = b.columns_for_outer_join>
...;

Nested query in Linq

I have three tables. I have to retrieve the data using Linq statement. My three table names are A,B,C. I connected join for connecting two tables A and B based on the id's like:
select ol, fN, LN, ci, co
from member
join details
on member_id = details_id
where details_id in
(select contacts_id from contacts where
contacts_id1 = 1 and contacts_usr_id = 1)
I am able to write the query up to the where condition, how can I write the query for the inner while condition?
you can try this:
var idlist = (from tbl in table3
where tbl.usr_id == 1 && tbl.contacts_id == 1
select tbl.contacts_id ).ToList();
var x = from A in table1
from B in table2 where A.user_id == B.user_id
&& idlist.Contains(A.user_id)
select new { a = A.a, b = A.b, c = A.c, d = B.d, e = B.e };
check and let me know if that work.
Try flipping the query upside down. How about the following:
var query =
from t3 in table3
where t3.user_id = 1 && t3.contacts_id = 1
join t2 in table2 on t3.contacts_id equals t2.usr_id
join t1 in table1 on t2.usr_id equals t1.userid
select new {t2.a, t2.b, t2.c, t1.d, t1.e};

Sql Server queries optimization techniques

My Stored Procedure takes a very long time to execute.
Can anyone suggest me what I can do to speed up the stored procedure, apart from using some good practices for writing down the queries.
I've heard about creating indices, but I'm not sure what are they.
Please suggest all the best ways to speed up my queries.
Thanks

Here are a few:
You should have indexes for every column in a WHERE clause. See
your SQL language for how to do it.
Learn how to EXPLAIN PLAN and see what's slow.
Stored procedure languages are functional, not set based. Use JOIN and don't fall into the (n+1) query/iteration trap.
Understand how using certain functions force you to TABLE SCAN in a WHERE clause.
