Insert into selecting BLOB column twice leads to SQLException: Restore of a
serializable or SQLData object of class error selecting from the table
--------------------------------------------------------------------------------------------------------------------------------------------------
Key: DERBY-3645
URL: https://issues.apache.org/jira/browse/DERBY-3645
Project: Derby
Issue Type: Bug
Components: SQL
Affects Versions: 10.3.2.2, 10.4.1.4, 10.5.0.0
Reporter: Kathey Marsden
The following code which inserts into a table by selecting a blob column twice
from another table, causes SQLException: Restore of a serializable or SQLData
object of class error selecting from the table. See attached program
DoubleInsertInto for full repro. Stack trace is below. Verified back to 10.3
but probably goes back further.
s.executeUpdate("CREATE TABLE T_MAIN(" +
"ID INT GENERATED ALWAYS AS IDENTITY PRIMARY KEY, " +
"V BLOB(590473235) )");
String ins1 = "INSERT INTO T_MAIN(V) VALUES (?)";
PreparedStatement ps;
ps = c.prepareStatement(ins1);
byte[] bytes = new byte[35000];
for (int i = 0; i < 35000; i++)
bytes[i] = (byte) i ;
ps.setBytes(1, bytes);
ps.executeUpdate();
ps.close();
s.executeUpdate("CREATE TABLE T_COPY ( V1 BLOB(2M), V2 BLOB(2M))");
Statement stmt = c.createStatement();
stmt.executeUpdate("INSERT INTO T_COPY SELECT V, V FROM T_MAIN");
ResultSet rs = stmt.executeQuery("SELECT * FROM T_COPY");
rs.next();
String v1 = rs.getString(1);
String v2 = rs.getString(2);
System.out.println("v1:" + v1);
System.out.println("v2:" + v2);
System.out.println("I am done");
