Command Line
When the Use Command Line property is set, the Command Line card setting provides the adapter-specific commands to connect to the data source and retrieve the input data. For example, if the input data is coming from a file, the Command Line specifies the name of the input file. If the input data is coming from a database, the Command Line might include the database name, user ID, password, and so on.
The command syntax for the source and target adapter commands is detailed in the adapter-specific documentation. The maximum length of a source or target adapter command is 2000 bytes. Limitations to the maximum adapter command length may apply to some adapters.
