PostHeaderIcon java.sql.SQLException: Wrong data type: NUMBER in statement [CREATE TABLE … (… NUMBER]

Case

In a JDBC DAO, I execute a query to retrieve an object. I get this error:

java.sql.SQLException: Wrong data type: NUMBER in statement [CREATE TABLE Jonathan_Table (TableColumn NUMBER]

Stacktrace

java.sql.SQLException: Wrong data type: NUMBER in statement [CREATE TABLE Jonathan_Table (TableColumn NUMBER]
 at org.hsqldb.jdbc.Util.throwError(Unknown Source)
 at org.hsqldb.jdbc.jdbcPreparedStatement.executeUpdate(Unknown Source)
 at com.bnpp.pb.risklayer.services.dao.jdbc.JdbcPrimeRiskServerDaoUnitTest.getDataSet(JdbcPrimeRiskServerDaoUnitTest.java:57)
 at org.dbunit.DatabaseTestCase.setUp(DatabaseTestCase.java:154)

Explanation and fix

My original DB is under Oracle, but my DBUnit tests works on HSQL. Yet, types NUMBER and VARCHAR2 are not available under HSQL, this is why the exception is raised.
To fixe the issue, rewrite your scripts, replacing NUMBER and VARCHAR2 with NUMERIC and VARCHAR.
