Fix Oracle CONCAT Error: Use ||

In Oracle, you can use || to concatenate strings as an alternative to the concat function. If the concat function doesn’t work, you can try using || instead, for example:

SELECT column1 || column2 AS concatenated_string
FROM your_table;

This will allow for string concatenation. If you still encounter issues, it may be due to mismatched data types or other syntax errors. Make sure to carefully check the SQL statement and data types before attempting to resolve it.
