Hi @asma gh ,
ORA-00936 missing expression Cause: A required part of a clause or expression has been omitted. For example, a SELECT statement may have been entered without a list of columns or expressions or with an incomplete expression. This message is also issued in cases where a reserved word is misused, as in SELECT TABLE.
Action: Check the statement syntax and specify the missing component.
The ORA-00936 happens most frequently:
1 - When you forget list of the column names in your SELECT statement.
2 - When you omit the FROM clause of the SQL statement.
Please check your query again to make sure the column and table name is correct.
Regards,
Zoe
