• What is the cause and solution for SAP error message DDLS350 - Column & is not contained in the GROUP BY list ?

  The SAP error message DDLS350 typically occurs in the context of SQL queries, particularly when using the GROUP BY clause in conjunction with aggregate functions. This error indicates that a column referenced in the SELECT statement is not included in the GROUP BY clause, which is a requirement in SQL when using aggregation.
  Cause:
  The error arises when you attempt to select a column that is neither an aggregate function (like SUM, COUNT, AVG, etc.) nor included in the GROUP BY clause. SQL requires that all selected columns that are not part of an aggregate function must be included in the GROUP BY clause to ensure that the results are logically grouped.
  Example:
  Consider the following SQL query:
  SELECT department, COUNT(employee_id)
  FROM employees
  GROUP BY department;
  If you try to add another column, such as employee_name, without including it in the GROUP BY clause, you will encounter the DDLS350 error:
  SELECT department, employee_name, COUNT(employee_id)
  FROM employees
  GROUP BY department;
  Solution:
  To resolve the DDLS350 error, you need to ensure that all non-aggregated columns in your SELECT statement are included in the GROUP BY clause. Here are a couple of approaches:
  
  
  Add the Column to the GROUP BY Clause:
  If you want to include employee_name, you should add it to the GROUP BY clause:
  SELECT department, employee_name, COUNT(employee_id)
  FROM employees
  GROUP BY department, employee_name;
  
  
  Use Aggregate Functions:
  If you want to summarize data without including the additional column in the grouping, you can apply an aggregate function to it. For example, if you want to get a list of employee names concatenated:
  SELECT department, STRING_AGG(employee_name, ', ') AS employee_names, COUNT(employee_id)
  FROM employees
  GROUP BY department;
  
  
  Related Information:
  
  SQL Standards: The requirement for columns in the GROUP BY clause is part of SQL standards to ensure that the results are well-defined.
  Aggregate Functions: Familiarize yourself with SQL aggregate functions, as they are essential for summarizing data.
  Database Documentation: Check the specific database documentation (e.g., SAP HANA, Oracle, etc.) for any nuances in SQL syntax or behavior.
  
  By ensuring that your SQL queries adhere to these principles, you can avoid the DDLS350 error and successfully execute your queries.
