ORA-00923: FROM keyword not found where expected
What it means
The SELECT list is malformed so the parser never reaches FROM in the place it expects it: missing comma between columns, alias with spaces not in double quotes, reserved word used as an alias, or a missing FROM (use FROM dual).
How to fix it
Check the commas in the SELECT list, put aliases with spaces in double quotes, and add FROM dual for SELECTs without a table (before Oracle 23ai).
