How can I concatenate two strings in Oracle?
The Oracle CONCAT function can only take two strings so the above example would not be possible as there are three strings to be joined (FirstName, ‘ ‘ and LastName). To achieve this in Oracle we would need to use the || operator which is equivalent to the + string concatenation operator in SQL Server / Access.
What happens when SQL concat function is null?
Note: If all the string passed in SQL CONCAT function have a NULL value, we get the output of this function also NULL. SQL CONCAT function implicitly converts arguments to string types before concatenation. We can use SQL CONVERT function as well without converting the appropriate data type.

Actually @sirketid, @uzman, @basvurukodu params works well, however the @ORA_BASVURU_KESIN_KOSUL param is causing a problem. I think because it has some sql-spesific expression like and, it is treated diffrently than simple variables used for comparison or assigning such as @sirket_id.
Is it possible to concat strings in soql?
Below is APEX code trying to find record with specified email. Even though the record is indeed in the database, it does not query anything. Debug shows “row (0)” which means empty is returned.

Can you do a caculation in a soql query?
You can’t do any caculation in SOQl as you do in SQL. So you can’t put this expression FirstName + ‘ ‘ + LastName in a SOQL query string. Anyway, if you wanna get the full name, why don’t you just use the Name filed which actually is a concat of FirstName and Lastname.
