I need to create a single SQL query which returns all the tables where the columns CREATED_By and UPDATED_BY are NULL.
I was able to do it on individual table which returns the rows where value is NULL, but i want all Tables Names only in database with NULL value, no need for the entire data to be returned.
Please help me on this!!
I am trying something like this, but unsuccessful,
SELECT DISTINCT `TABLE_NAME` FROM INFORMATION_SCHEMA.COLUMNS WHERE `COLUMN_NAME` LIKE ("%CREATED_BY%" and "%UPDATED_BY%")IS NULL or `COLUMN_NAME` LIKE ("%CREATED_BY%" and "%UPDATED_BY%") = ' ' ORDER BY `UPDATED_BY` DESC
As Robert mentioned, you can do this via a stored proc call by writing dynamic SQL and taking a parameter for "TABLE_NAME". It will replace the actual select query's table name in run time by passing an input. If you want to do this for each table then a looping function can be utilized.
Keep in mind the size of tables and the number of tables you're looping on though.
