Storing WHERE clauses in a global table - sql

Question

I'm running this query 50+ times, and I want to abstract the AND query statements below and store them in one/global table, so in the future I only have to edit one table (vs. 50) if I want to edit any of the AND statements. What's the most efficient way to store the AND statements in a separate table and then cal them in the below query?
SELECT
Field,
Field2,
Field3
into table1
FROM table2
WHERE (DESCRIPTION iLIKE '%ADVANCE%AUTO%Pa%')
AND is_duplicate!=1
AND amount >0
AND currency_id = 152
AND transaction_base_type = 'debit'
AND TRANSACTION_STATUS <> 'D'

Answer 1

You could create a view/materialized view:
CREATE VIEW my_view
AS
SELECT
Field,
Field2,
Field3,
DESCRIPTION
FROM table2
WHERE is_duplicate!=1
AND amount >0
AND currency_id = 152
AND transaction_base_type = 'debit'
AND TRANSACTION_STATUS <> 'D'
and then:
SELECT Field, Field2, Field3
FROM my_view
WHERE (DESCRIPTION iLIKE '%ADVANCE%AUTO%Pa%')
EDIT
I simply need to store WHERE clauses in one place so I can update them once and call them in 50 queries vs. including them in every query and updating them 50 times. Is it really that complicated?
As I wrote in comment you cannot simply parametrize table name(plus it may indicate that schema is flawed). SQL is powerful language so you could use dynamic SQL and functions.
CREATE OR REPLACE FUNCTION my_func(tab_name text)
RETURNS TABLE (
id INT, -- here goes common column list shared across all 50 tables
col1 INT,
col2 INT
)
LANGUAGE 'plpgsql'
AS $BODY$
BEGIN
RETURN QUERY
EXECUTE format('SELECT * from %I where col2 > 0',tab_name);
-- here goes shared conditions
END
$BODY$;
SELECT * FROM my_func('tab1');
SELECT * FROM my_func('tab2') WHERE col2 = 2;
-- condition that is not shared
