The parameters for \install, for installing SQL-MapReduce functions and files:
- The argument, file_pathname, is the path name of the to-be-installed file, relative to the directory where ACT is running. When you install a function, the name of the file must match the name of the function. See Build and Package the SQL/MR Function.
- The optional schemaname parameter specifies the schema in which the function will be installed. To install a file or function, your SQL user account must have the INSTALL FILE privilege in the schema. If you’re installing a function, your account must also have the CREATE FUNCTION privilege in the schema.
- The optional installed_filename parameter specifies the name of the file or function, as it will be referred to in an Aster instance. The installed_filename is the name SQL users will use when they SELECT from the function. You must use the file's actual filename, including its suffix, but not including any directory names. We strongly recommend that all letters in the function name be lowercase. If the name contains any uppercase letters, users will have to surround the function name in double quotes in their SELECT statements that call the function.
