# Qora2 |
||||||
|
|
||||||
|
To use: |
||||||
|
|
||||||
|
- Use maven to fetch dependencies. |
||||||
|
- Build project. |
||||||
|
- Fire up an old-gen Qora node. |
||||||
|
- Run ```src/test/update.java``` as a JUnit test to build DB structure. |
||||||
|
- Run ```src/test/migrate.java``` as a JUnit test to migrate old Qora blocks to DB. |
||||||
|
|
||||||
|
You should now be able to run ```src/test/load.java``` and ```src/test/save.java``` |
||||||
|
as JUnit tests demonstrating loading/saving Transactions from/to database. |
||||||
|
|
||||||
|
You can also examine the migrated database using |
||||||
|
[HSQLDB's "sqltool"](http://www.hsqldb.org/doc/2.0/util-guide/sqltool-chapt.html). |
||||||
|
|
||||||
|
It's a good idea to install "rlwrap" (ReadLine wrapper) too as sqltool doesn't |
||||||
|
support command history/editing! |
||||||
|
|
||||||
|
Typical command line for sqltool would be: |
||||||
|
``` |
||||||
|
rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC} qora |
||||||
|
``` |
||||||
|
|
||||||
|
```${HSQLDB_JAR}``` contains pathname to ```hsqldb-2.4.0.jar```, |
||||||
|
typically ```${HOME}/.m2/repository/org/hsqldb/hsqldb/2.4.0/hsqldb-2.4.0.jar``` |
||||||
|
|
||||||
|
```${SQLTOOL_JAR}``` contains pathname to where you |
||||||
|
[downloaded sqltool-2.2.6.jar](http://search.maven.org/remotecontent?filepath=org/hsqldb/sqltool/2.2.6/sqltool-2.2.6.jar) |
||||||
|
|
||||||
|
```${SQLTOOL_RC}``` contains pathname to a text file describing Qora2 database, |
||||||
|
e.g. ```${HOME}/.sqltool.rc```, with contents like: |
||||||
|
|
||||||
|
``` |
||||||
|
urlid qora |
||||||
|
url jdbc:hsqldb:file:db/test |
||||||
|
username SA |
||||||
|
password |
||||||
|
``` |
||||||
|
|
||||||
|
You could change the line ```url jdbc:hsqldb:file:db/test``` to use a full pathname for easier use. |
||||||
|
|
||||||
|
Another idea is to assign a shell alias in your ```.bashrc``` like: |
||||||
|
``` |
||||||
|
alias sqltool='rlwrap java -cp ${HSQLDB_JAR}:${SQLTOOL_JAR} org.hsqldb.cmdline.SqlTool --rcFile=${SQLTOOL_RC}' |
||||||
|
``` |
||||||
|
So you can simply type: ```sqltool qora``` |
