Provides the capability to unload an UltraLite Java edition database—either the data, the schema, or both—to an XML file.
SyntaxULjUnload -c filename -p password [ options ] outputfile
| Options | Description |
|---|---|
| -b max-blob-size | Maximum size (in bytes) of blob/char data output to XML. |
| -c filename | Required. Name of database file to unload. |
| -d | Unload only data; do not output schema information. |
| -e table, ... | Exclude data for tables named in list. |
| -f directory | Directory to store data for columns larger than max blob size specified with -b option. |
| -n | Unload schema information only; do not output data. |
| -p password | Password to connect to database. The default is sql. |
| -q | Run in quiet mode—do not display messages. |
| -t table, ... | Only output data for tables named in list. |
| -v | Display verbose messages. |
| -y | Overwrite output file if it already exists. |
| -? | Display option usage/help information. |
| outputfile | Output file name (this file contains xml statements that describe the database contents). |
Example for unloading blobfile typesApply the following sample SQL statement to your database to unload a blobfile type:
CREATE TABLE blobfile_example
file_name CHAR(size) DEFAULT AUTOFILENAME( prefix, extension ),
file_contents LONG BINARY STORE AS FILE( file_name ) [ CASCADE DELETE ] |
When applying this example and using this utility, ULjUnload exports the file_name column as a regular CHAR but with an additional attribute, default_autofilename, which stores the prefix and extension strings in the form 'prefix', 'extension'. The file_contents column is exported as a LONG BINARY but with an additional attribute, filename_col, which stores the name of the referenced file_name column. In the row containing the blobfile columns, the content of the file_name column is unchanged. The file_contents column behaves like an externally-stored blob column and has the following form:
file_contents.File="tablename-columname-rownumber.bin" |
The contents of the file_contents column are saved as bin files to the location specified by the -f option.
