Using IS NOT NULL for multiple columns - sql-server

Question

I want to check for the is not null constraint for multiple columns in a single SQL statement in the WHERE clause, is there a way to do so?
Also I don't want want to enforce the NOT NULL type constraint on the column definition.
SELECT * FROM AB_DS_TRANSACTIONS
WHERE FK_VIOLATION IS NULL
AND TRANSACTION_ID NOT IN(
SELECT distinct TRANSACTION_ID FROM AB_TRANSACTIONS)
AND COUNTRY_ID IS NOT NULL
AND GEO_CUST_COUNTRY_ID IS NOT NULL
AND INVOICE_DATE IS NOT NULL
AND ABB_GLOBALID IS NOT NULL
AND SALES_ORG_ID IS NOT NULL
AND DIST_ID IS NOT NULL
AND CUSTOMER_ID IS NOT NULL
AND REPORT_UNIT_ID IS NOT NULL
AND CURR_INVOICE IS NOT NULL
AND DIVISION_CODE IS NOT NULL
So instead of using IS NOT NULL again and again I want to simplify things

Answer 1

You can use
SELECT * FROM table1
WHERE NOT (Column1 IS NULL OR
Column2 IS NULL OR
Column3 IS NULL OR
Column4 IS NULL
IS NOT NULL)
As per OP comment, Updating answer
Inserting Rows by Using INSERT and SELECT Subqueries
INSERT INTO Table_A
SELECT column1, column2, column3,column4
FROM Table_B
WHERE NOT (Column1 IS NULL OR
Column2 IS NULL OR
Column3 IS NULL OR
Column4 IS NULL
IS NOT NULL);
Your query
I am able to reduce 50 chars approx
SELECT * FROM AB_DS_TRANSACTIONS
WHERE
FK_VIOLATION IS NULL
AND TRANSACTION_ID NOT
IN(SELECT distinct TRANSACTION_ID FROM AB_TRANSACTIONS)
AND
NOT (
COUNTRY_ID IS NULL
OR GEO_CUST_COUNTRY_ID IS NULL
OR INVOICE_DATE IS NULL
OR ABB_GLOBALID IS NULL
OR SALES_ORG_ID IS NULL
OR DIST_ID IS NULL
OR CUSTOMER_ID IS NULL
OR REPORT_UNIT_ID IS NULL
OR CURR_INVOICE IS NULL
OR DIVISION_CODE IS NULL
)

Answer 2

SELECT * FROM AB_DS_TRANSACTIONS
WHERE COALESCE(COUNTRY_ID,GEO_CUST_COUNTRY_ID,INVOICE_DATE,ABB_GLOBALID,SALES_ORG_ID,DIST_ID,CUSTOMER_ID,REPORT_UNIT_ID,CURR_INVOICE,DIVISION_CODE) IS NOT NULL

Answer 3

I think the syntax that you are looking for to show only those rows where all are not null is this
SELECT * from table_B
where COLUMN1 is not null and COLUMN2 is not null and COLUMN3 is not null

Answer 4

In BigQuery (might work in other db)- I would use the concat-function. Make sure to have strings or cast fields to strings where needed. Concat returns null if one of the fields is null.
SELECT * FROM AB_DS_TRANSACTIONS
WHERE FK_VIOLATION IS NULL
AND TRANSACTION_ID NOT IN(
SELECT distinct TRANSACTION_ID FROM AB_TRANSACTIONS)
AND concat(COUNTRY_ID,GEO_CUST_COUNTRY_ID,INVOICE_DATE,ABB_GLOBALID,SALES_ORG_ID,DIST_ID,CUSTOMER_ID,REPORT_UNIT_ID,CURR_INVOICE,DIVISION_CODE) IS NOT NULL

Answer 5

I think one strategy can be using least function?
The limitation here would be that all the arguments must be of the same type, so looks like OP's columns may need to be converted to a str or something.
If we can get past that limitation, I think the below should work to check if any of the columns are null:
SELECT *
FROM AB_DS_TRANSACTIONS
WHERE FK_VIOLATION IS NULL
AND TRANSACTION_ID NOT IN( SELECT distinct TRANSACTION_ID FROM AB_TRANSACTIONS)
AND least(COUNTRY_ID
,GEO_CUST_COUNTRY_ID
,INVOICE_DATE
,ABB_GLOBALID
,SALES_ORG_ID
,DIST_ID
,CUSTOMER_ID
,REPORT_UNIT_ID
,CURR_INVOICE
,DIVISION_CODE
) IS NOT NULL
;
ps - using snowflake.

Answer 6

It seems like this should be the elegant one:
(at least for newer versions of MSSQL)
SELECT * FROM tbl WHERE NOT COL1+COL2+COL3+COL4 IS NULL
