DatabaseMetaData dbmd = dbConnection.getMetaData();
ResultSet result = dbmd.getTables("%", Ousername, "%", new String[]{ "TRIGGER" });
while (result.next()) {
result.getString("TABLE_NAME")
}
DatabaseMetaData dbmd = dbConnection.getMetaData();
ResultSet result = dbmd.getTables("%", Ousername, "%", new String[]{ "TRIGGER" });
while (result.next()) {
result.getString("TABLE_NAME")
}
