This activity selects and returns Row(s) from an Oracle a DB2 Server database table.
Activity Parameters
The Select Row(s) from Table activity parameters can be provided by manual inserted values or via IN arguments or variables:
Parameters:
- Distinct (combo box control) (type: string): whether the returned values should be distinct or not.
- Fields (text box editor type) (type: string): the column headers that you want to be returned with the select command. If you enter more than one you should separate them with ','. If all fields needs to be returned, then just use "*". The " * " has the same role as used in the SQL select all statement: select * from table
- Order By (text box editor type) (type: string): the column header that you want to result to be ordered by. For example, if "ID" is inserted, then the values returned will be ordered depending on the value set in the ID column. If no value is provided, the activity will return the values in the same order as taken from the table.
- Order by Direction (combo box control) (type: string): choose to order the resulted rows in Ascending or Descending direction. It will be ignored if Order By is not set.
- Table (text box editor type) (type: string): the table name on which to run the select.
- WHERE (text box editor type) (type: string): the Where statement. For example: ID>2, where ID is a column header.

A more complex example, with fields, orders and statements can be seen in the image below:
Execution: In the Tracking Data there can be seen the returned results:
The same result can be seen when executing the same SQL Select query from Oracle Application ExpressDB2 (IBM Data Studio was used for the examples):
