Default: The same name as the control file, but with an extension of .
DATA parameter specifies the name(s) of the data file(s) containing the data to be loaded.
Syntax and Description
The file specification can contain wildcards (only in the file name and file extension, not in a device or directory name). An asterisk (*) represents multiple characters and a question mark (?) represents a single character. For example:
To list multiple data file specifications (each of which can contain wild cards), the file names must be separated by commas.
If the file name contains any special characters (for example, spaces, *, ?, ), then the entire name must be enclosed within single quotation marks.
The following are three examples of possible valid uses of the
DATA parameter (the single quotation marks would only be necessary if the file name contained special characters):
DATA='file1','file2' DATA='file3,'file4','file5' DATA='file6'
DATA='file1' DATA='file2' DATA='file3' DATA='file4' DATA='file5' DATA='file6'
If multiple data files are being loaded and you are also specifying the
BAD parameter, it is recommended that you specify only a directory for the bad file, not a file name. If you specify a file name, and a file with that name already exists, then it is either overwritten or a new version is created, depending on your operating system.
If you specify data files on the command line with the
DATA parameter and also specify data files in the control file with the
INFILE clause, then the first
INFILE specification in the control file is ignored. All other data files specified on the command line and in the control file are processed.
If you specify a file processing option along with the
DATA parameter when loading data from the control file, then a warning message is issued.
The following example specifies that a data file named
employees.dat is to be loaded. The .
dat extension is assumed as the default because no extension is provided.
