Unloads UltraLite version 8.0.2 to 9.0.x databases and/or schema files (*.usm) into an XML file.
ulunloadold -c "connection-string" [ options ] xml-file
| Option | Description |
|---|---|
| -b max-size | Set the maximum size of column data to be stored in the XML file. The default is 10 KB. To store all data in the XML file (no maximum size), use -b -1. |
| -c "connection-string" | Required. Connect to the database as identified in the DBF or file_name parameter of your connection-string. If you do not specify both a user ID and a password, the default UID of DBA and PWD of sql are assumed. |
| -f directory | Set the directory to store data larger than the maximum size specified by -b. The default is the same directory as the XML file. |
| -q | Set the utility to run in quiet mode. Suppress informational banners, version numbers, and status messages. Error messages are still displayed, however. |
| -v | Print verbose messages. |
| -y | Overwrite xml-file without confirmation. |
| xml-file | Set the name of the XML file that data will be unloaded into. |
UltraLite version 11 cannot directly upgrade version 8.x or version 9.x databases. Use this tool to generate an XML file that can then be used by ulload to create a version 11 database. Do not unload UltraLite version 11 databases with this utility. Use the ulunload utility instead.
Unloading a database does not preserve:
To confirm what database options or properties have been preserved, run ulinfo after you have reloaded your database with the ulload utility.
If column data exceeds the maximum size you specified with -b, the overflow is saved to a *.bin file in either:
The file name follows this naming convention:
tablename-columname-rownumber.bin |
Any error code value other than 0 means that the operation failed.
This utility cannot be used to unload databases directly on Windows Mobile devices. You must first copy them to a desktop computer.
Upgrading an UltraLite 8.0.x schema file named dbschema8.usm into an UltraLite version 11 database named db.udb requires these two commands:
ulunloadold -c SCHEMA_FILE=dbschema8.usm dbschema.xml |
ulload -c DBF=db.udb dbschema.xml |
Upgrading an UltraLite version 9.0.x database for Palm OS named palm9db.pdb to an UltraLite version 11 database named palm11db.pdb requires these two commands:
ulunloadold -c DBF=palm9db.pdb dbdata.xml |
ulload -c DBF=palm11db.pdb -p Syb1 dbdata.xml |
