The following table describes the things to consider when using the RUN command.
| Topic | Usage Notes |
|---|---|
| z/OS fileid Usage Rules | If a DDNAME is specified, Teradata FastLoad reads data records from the specified source. A DDNAME must obey the same construction rules as Teradata SQL column names except that:
The DDNAME must obey the applicable rules of the external system and may reference a sequential or VSAM data set. If the DDNAME represents a data source on magnetic tape, the tape may be either labeled or nonlabeled, as supported by the operating system. |
| Executing the RUN Command | After Teradata FastLoad executes the RUN command, it reads additional commands from the specified source until a LOGOFF command or end-of-file condition is encountered, whichever occurs first. An end-of-file condition automatically causes Teradata FastLoad to resume reading its commands and DML statements from the previously active source:
SYSIN/stdin remains the active input source after Teradata FastLoad processes any user-provided invocation parameters.
|
| Nested RUN Commands | The source specified by a RUN command can have up to five levels of nested RUN commands. |
