Liquibase - how to generate a changelog for existing database
I'm trying to use liquibase for generating the changeLog, starting by snapshoting the current state of my database.
Environment details:
- OS: Windows 7 32 x86,
- Java JDK 1.7,
- mysql jdbc driver from MySQL
- liquibase 2.0.5.
I run the following from command line:
liquibase --driver=com.mysql.jdbc.Driver --changeLogFile=./structure.xml --url="jdbc:mysql://mysql.mysite.com" --username=<myuser> --password=<mypass> generateChangeLog
It runs fine, and generated the output file. But the output file just contains:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-2.0.xsd"/>
And no tables are created on my database (I was expecting the two tables used for tracking).
What am I missing?
EDITS
Yes, I'm referring to liquibasechanlog and liquibasechangelock tables. I know they should automatically appears on database. My question is why they aren't there. And yes, the provided user have the rights granted for doing such task.
And it is not an empty database. It has near 20 tables, 10 views, data...
Answer
Just specify the database name with the --url flag like ZNK said:
--url="jdbc:mysql://mysql.mysite.com/database_name_here"
