1 | FrontBase is now available for free. Please see the FrontBase website [[http://www.frontbase.com]] for details. | ||

5 | **Useful SQL commands in FrontBase** | ||
6 | |||
7 | {{code value="sql"}} | ||
8 | |||
9 | // writes an ascii backup of your database | ||
10 | write all output(dir='/path/to/export/dir', type = 'FrontBase', content=true); | ||
11 | |||
12 | // creates a database from the exported files that results from the previous command | ||
13 | SCRIPT <path-to-export-directory>/schema.sql; | ||
14 | |||
15 | // to rename a table | ||
16 | alter table name Item to ItemArchive; | ||
17 | |||
18 | {{/code}} | ||

20 | If you don't use type='FrontBase', you end up losing precision on your timestamp columns, which can really suck. | ||

24 | A first experience with FrontBase, WO 5.3.1 and MacOSX 10.4.6 | ||
25 | |||
26 | Make sure you have the FrontBase jdbc connector accessible from your WebObjects applications. I placed mine in /Library/Java/Extensions/ | ||
27 | Make sure that the FrontBasePlugIn.framework is located in /Library/Java/Frameworks | ||
28 | Make sure that you have added the framework to your project or you will not be able to establish a connection to your database, even though you'll be able to see your database from EOModeler. | ||
29 | If you haven't yet assigned a User/Password combination to your database, you still must include User information in order for the connection to be established. Use system to get started. The URL for basic connection is: jdbc:FrontBase:~/~/localhost/my_database_name | ||
30 | |||
31 | The documentation available at the Frontbase site is very complete. The only gotcha was that I was left with the impression the framework was only necessary for WebObjects 4.5 and below. This is not the case, you have to install and include it for WO 5 projects too. | ||
32 | |||
33 | **Migration from MySQL** | ||
34 | |||
35 | In most cases the datatypes are exactly the same. Here are the FrontBase equivalents for common datatypes in MySQL that are different: | ||
36 | |||
37 | TEXT -> CLOB | ||
38 | |||
39 | DATETIME -> TIMESTAMP | ||
40 | |||
41 | INT -> INTEGER | ||
42 | |||
43 | MEDIUMBLOB -> BLOB |
