How do return all columns in Table A where an ID column is present in Table B which contains hundreds of ID columns
sql query to get column names from table
sql select from multiple tables
sql code example
sql query examples from multiple tables
I understand how to check if Column ID in Table A is present in Table B Column X.
But is there a way to return all rows in Table A in which it does NOT match a single Identifier in Table B?
In reality, Table B contains hundreds of columns.
+------------+------+--------+----------------+ | Title Name | ID | Region | Numeric Column | +------------+------+--------+----------------+ | Sam | B021 | NA | 5.99 | | Brook | B026 | EU | 5.99 | | Harry | B032 | KOR | 10.99 | +------------+------+--------+----------------+
+------+-------+-------+ | SAM | BROOK | HARRY | +------+-------+-------+ | B021 | B024 | B030 | | 1 | B025 | B031 | | 2 | 4 | | | 3 | | | +------+-------+-------+
So in this instance, I would like my query to SELECT Rows 2 & 3 in Table A.
Using a NOT EXISTS could work.
SELECT * FROM TableA a WHERE NOT EXISTS ( SELECT 1 FROM TableB b WHERE a.ID IN (b.SAM, b.BROOK, b.HARRY) );
Chapter 16 SQL Data Manipulation Language – Database Design , SELECT – to query data in the database; INSERT – to insert data into a table; UPDATE If a clause has several parts, they should appear on separate lines and be All trailing spaces are removed from data inserted into varchar columns , To insert rows into a table with an IDENTITY column, follow the below example. I am using this but it is taking long time. Table contains around 3 million records select a.* from demo_test a, demo_test b where a.column_1 = b.columns_1 and a.column_2 = b.column_2 and a.column_3 != b.column_3 and a.status is null Please suggest if you have a better option and indexes if I have to make.
I would use the
NOT IN function to where,
SELECT * FROM TABLE A WHERE col_A NOT IN (SELECT col_A FROM TABLE B)
This will return all the rows from
TABLE A where the val of
col_A is not in
Hope this is helpful!

Basically, you have to enumerate all the columns that might be null in one expression. So for a table with possibly null columns a, b, c, you could do this: SELECT key_column, COALESCE(a,0) + COALESCE(b,0) + COALESCE(c,0) null_col_count FROM my_table

If you have a column in

not null (say, column
where clause can be simplfied:
select ta.* from tableA ta left join tableB tb on ta.id in (tb.sam, tb.brook, tb.harry) where tb.never_null is null
