Why do I receive empty or blank data in my report but should receive concatenated string data?
Oracle B2C Service, All supported versions
CONCAT is a standard SQL function that concatenates two strings to return a concatenated string. When creating report it is very important to remember that concatenating a NULL value to a string results in a NULL value.
For example we need a contact information to be returned in one string:
If even one of those fields is empty then a blank record will be displayed because the concatenated string will be nulled.
This is the industry-wide SQL standard.
