H2 database inserting data exception after adding new column with ALTER TABLE - jdbc

Question

I am adding new column to my table like below code:
String sql = "ALTER TABLE PROJE_ALAN ADD NEWCOLUMN VARCHAR(30)";
PreparedStatement ps = conn.prepareStatement(sql.toString());
ps.execute();
conn.close();
ps.close();
This is adding a new column to my table but when I want to add new data throws an exception:
Caused by: org.h2.jdbc.JdbcSQLException: General error: "net.sourceforge.hatbox.RTreeInternalException: Unable to select meta node"; SQL statement: INSERT INTO "PROJE_ALAN" ( "THE_GEOM","JJ","KK","NEWCOLUMN" ) VALUES ( ST_GeomFromText ('MULTIPOLYGON (((-244856.06897661195 4166022.019422841, 189248.78294214187 4442270.561552957, 778743.439809086 4301679.785647452, 662817.7123080553 4101892.893571207, 83189.0748029009 3707252.1190996123, -244856.06897661195 4166022.019422841)))',23036),'','','') [50000-172]

If I restart my application then I can add new data to new table. I think problem can be refreshing indexes without restarting application. Maybe It is related with Hat Box.
So what am I missing?

Answer 1

It's not Hatbox's fault. It's a bug in H2. H2 engine is recreates triggers after an ALTER TABLE statement, but calling trigger.init with TEMP TABLE NAME. Because of that, the trigger is being initialized with the wrong table name. After creating triggers, H2 renames the table to the original value.
My workaround for this bug is (it's buggy too, but working):
Changed net.sourceforge.hatbox.jts.Insert, Update, Delete trigger init methods to
public void init(Connection con, String schema, String trigger, String table,
boolean before, int type) throws SQLException {
this.schema = schema;
this.table = table;
if(this.table.contains("_COPY_")) {
this.table = table.substring(0, table.indexOf("_COPY_"));
}
}
You have to be while using this, if you have COPY on your table name, it will not work. You may change _COPY_ to *_COPY_?_? like regex matching.
