Question

I have SQL query design as below.

SELECT (THIS ITEMS) 
FROM (TABLES) 
WHERE(SOME CONDITION) AND NOT IN (CONDITION) AND IN (CONDITION)

But not getting proper output as required, as ‘IN’ condition isn’t wrking properly

Answer 1

You need a column to compare to. Proper syntax is (note the column_expression):

SELECT <select_list>
FROM <table_expression>
WHERE <column_expression> [NOT] IN (<comparison_list>)

For example,

SELECT col1, col2
FROM tab
WHERE col3 IN ('yes', 'no')
AND col4 NOT IN ('no', 'maybe')

Note you can also use a single-column result set instead of a static comparison list, as in:

SELECT col1, col2
FROM tab
WHERE col3 IN (SELECT filterValues FROM table2)

but it is much more optimal to use an EXISTS clause for this case:

SELECT col1, col2
FROM tab
WHERE EXISTS (SELECT 1 FROM table2 WHERE filterValues = col3)
