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.sql'
.
try (Connection con = ...;
Statement stmt = conn.createStatement()) {
stmt.executeQuery(String.format("SCRIPT TO '%s'", sqlFilePath));
}
If you want to backup it as a ZIP archive , you can use BACKUP TO 'path/to/my/file.zip'
.
try (Connection con = ...;
Statement stmt = conn.createStatement()) {
stmt.executeQuery(String.format("BACKUP TO '%s'", zipFilePath));
}
