Syntax Elements

name

Name for the package.

The name that you use here to distribute the package is the same name that you specify later in the CREATE/REPLACE statement that you use to install the package.

version

Version you assign to the package.

For example, when you initially distribute a package, you might want to assign a version of '1.0'. When you update the package and redistribute it, you might want to assign a version of '2.0' or '1.1', depending on the changes to the package.

filename

Name to use for the server-side destination file.

The filename you specify here to distribute the package is the same filename that you specify later in the CREATE/REPLACE statement to install the package.

path

Optional path to use for the server-side destination file. The path you specify is relative to the following fixed path:

teradata_installation_path/Teradata/dem

where teradata_installation_path is the path of the Teradata installation. To get the value of teradata_installation_path, enter the following on the command line:

pdepath -I

The full path to the server-side destination file is formed by appending the relative path specified by path to the fixed path. If you omit the path argument, the full path is the same as the fixed path.

The installsp stored procedure returns the full path in the cfgpath OUT argument.

source

USING variable name preceded by a COLON character.

When you call installsp to distribute a package, the CALL statement that you use must specify a USING row descriptor. During processing, installsp replaces source with the contents of the package.

operation

the operation to perform on the package. The valid values are listed below. They are case insensitive.

• 'CREATE', which specifies to copy the contents of the package specified by source to all nodes in the location specified by path with the name specified by filename. If the file already exists, do not overwrite it.
• 'REPLACE', which specifies to copy the contents of the package specified by source to all nodes in the location specified by path with the name specified by filename. Overwrite the target file if it exists.
• 'DROP', which specifies to delete the file named filename in the location specified by path.
• 'CHECK', which specifies to not perform an operation on the package, but simply return the target platform type in the pform argument.

pform

Target platform type, for example LINUX64.

cfgpath

Full path on the server where the package has been distributed, formed by appending the relative path specified by path to the fixed path for the target platform.

Later, when you use an appropriate CREATE/REPLACE statement to install the package, use the return value of cfgpath in the EXTERNAL NAME clause to specify the full path to the server-side destination file.
