Unable to reach my H2 table from Matlab (but able from Java) - matlab

Question

The following Java code works:
public class TestH2Schema {
public static void main(String[] args) throws SQLException {
Driver driver = new org.h2.Driver();
Connection conn = driver.connect("jdbc:h2:file:D:/Users/Dims/Design/TESTS/SVHN_DB/db/svhn", null);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT ID FROM IMAGE WHERE PATH='train/1.png';");
while(rs.next()) {
System.out.println(rs.getLong("ID"));
}
rs.close();
stmt.close();
conn.close();
}
}
The following equivalent code in Matlab does not work:
driver = org.h2.Driver;
props = java.util.Properties;
conn = driver.connect('jdbc:h2:file:D:/Users/Dims/Design/TESTS/SVHN_DB/db/svhn', props);
stmt = conn.createStatement();
query = 'SELECT ID FROM IMAGE WHERE PATH=''train/1.png''';
rs = stmt.executeQuery(query);
while rs.next()
rs.getLong('ID')
end
rs.close();
stmt.close();
conn.close();
doesn't work causing exception
org.h2.jdbc.JdbcSQLException: Table IMAGE not found; SQL statement:
UPDATE
If I query
query = 'SELECT * FROM INFORMATION_SCHEMA.TABLES;'
I see a list of tables, but not mine ones. Looks like Matlab is somehow looking at different location or someting.

Answer 1

matlab search in "MatlabDatabase" (or another default data-source)
to use your own defined data-source you should declare it first
for example:
q1='use your_datasource';
q2='select * from INFORMATION_SCHEMA.TABLES';
exec(conn,q1);
exec(conn,q2);
