• What is the cause and solution for SAP error message DDLST012 - An empty column list is not allowed ?

  The SAP error message DDLST012, which states "An empty column list is not allowed," typically occurs when you are trying to execute a SQL statement that requires a list of columns, but the list is empty. This can happen in various contexts, such as when creating a table, inserting data, or updating records.
  Cause:
  
  Empty Column List: The most common cause is that the SQL statement is missing the column names in the list. For example, if you are trying to create a table or insert data without specifying any columns, the system will throw this error.
  Dynamic SQL Issues: If you are using dynamic SQL to construct your queries, there may be a logic error that results in an empty column list being generated.
  Incorrect Syntax: There may be a syntax error in your SQL statement that leads to an empty column list being interpreted.
  
  Solution:
  
  
  Check SQL Statement: Review the SQL statement that triggered the error. Ensure that you have specified the required columns correctly. For example:
  
  Creating a Table: Ensure you have defined the columns in the CREATE TABLE statement.
  Inserting Data: Ensure you have specified the columns in the INSERT INTO statement.
  Updating Data: Ensure you have specified the columns in the UPDATE statement.
  
  Example of a correct INSERT statement:
  INSERT INTO table_name (column1, column2) VALUES (value1, value2);
  
  
  Dynamic SQL Debugging: If you are using dynamic SQL, add debugging statements to log the generated SQL before execution. This will help you identify if the column list is being constructed correctly.
  
  
  Review Logic: If the column list is being built programmatically, check the logic that populates this list to ensure it is not inadvertently resulting in an empty list.
  
  
  Consult Documentation: If you are unsure about the syntax or requirements for your SQL statement, refer to the SAP documentation or SQL reference for guidance.
