h2

We have a legacy schema file which has the following column names, would like to understand if any of them would cause an issue if we port our application to h2, mysql, postgres or oracle. e.g how would I know if using this would be ok across the databases listed below. Are there any good tools which can do a preliminary check on this? key when size type count from with Should be quite easy to get the list of reserved words and build a table of the reserved words. Here are some lists of reserved words: Oracle: http://download.oracle.com/docs/cd/B19306_01/em.102/b40103/app_oracle_reserved_words

I have couple of entities in my data layer stored in particular schema. For example: @Entity @Table(name = "FOO", schema = "DUMMY") public class Foo {} I'm trying to setup H2 embedded database for integration testing of my data layer. I'm using @DataJpaTest annotation for my tests to get H2 embedded database configured automatically. However, the creation of tables fails because schema DUMMY is not created at DB initialization. Any ideas on how to create schema before creation of tables in test cases? I've tried to use @Sql(statements="CREATE SCHEMA IF NOT EXISTS DUMMY") but didn't succeed.

We have developed an app, which creates obligations in vault in a table. If the row size of the table is less than 200, the application works fine. However, if the rows are more than 200 then during the execution it gives the following error - Please specify a PageSpecification as there are more results [201] than the default page size [200] After increasing the pagination to 400 from the default 200, I am getting java heap out of memory error. I tired to increase the heap size of node from 512m (default) to 1024m. But, still this issue is not resolved and I am getting the error in H2 DB-

I am using an ORM (ORMlite) and all my calls are going well until I get the following error. Exception in thread "main" org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement " SELECT * FROM ""STORIES"" WHERE ""TITLE"" = 'Deepcut case leads 'NOT FOLLOWED[*]'' "; SQL statement: SELECT * FROM Stories WHERE title = 'Deepcut case leads 'not followed'' [42000-152] at org.h2.message.DbException.getJdbcSQLException(DbException.java:327) at org.h2.message.DbException.get(DbException.java:167) at org.h2.message.DbException.get(DbException.java:144) at org.h2.message.DbException.getSyntaxError

I have an application with h2 database. I want to create .sql file using SCRIPT command in Java. If I am executing it using Prepared Statement: PreparedStatement stmt = con.prepareStatement("SCRIPT"); ResultSet rs = stmt.executeQuery(); Then how can I able to get whole result in single String. I am new to Java so unable to find the way out to get result of that query because it doesn't contains column names in it. Then I will write it in file using InputStream . If you want to backup into a file, the content of your H2 instance as a SQL script , you can directly use SCRIPT TO 'path/to/my/file

I am trying to build an SQL schema for a system where we have channels , each with an id , and one or more fixtures . I am having difficulty finding a way to implement this one-to-many mapping. (i.e. One channel to many fixtures ). I am using the H2 database engine . I cannot have a table : id | fixture ----|---------- 1 | 1 1 | 2 2 | 3 CREATE TABLE channel( id INT NOT NULL PRIMARY KEY, fixture INT NOT NULL ); ... as the PRIMARY KEY id must be UNIQUE . Similarly, I cannot map as follows: CREATE TABLE channel( id INT NOT NULL PRIMARY KEY, f_set INT NOT NULL REFERENCES fixtures(f_set) ); CREATE

I'm testing a controller that returns a json response but the tests fail after the first time because the h2 database does not reset the auto increment id. Using fixtures or creating objects manually has a same problem. @Before public void setUp() { Fixtures.deleteAllModels(); Fixtures.loadModels("data.yaml"); } How to solve this problem? Start your play app, fire up browser with this url (if you run play app locally): http://localhost:9000/@db Enter your h2 db, and type the command below and run: ALTER TABLE <table_name> ALTER COLUMN <column_name> RESTART WITH 1 If you'd like to do this
