Problem with create table in Derby 10.2.2.0

Hy
I'm try to using Derby 10.2.2.0
<http://db.apache.org/derby/releases/release-10.2.2.0.cgi>  in embedded
mode with the integrated plug-in environment in Eclipse 3.2.0.
Environment jre 1.6.0
I would create a table with this code :
public boolean tableCreation(Connection currentConn, String Table)

                    throws DatabaseDriverException {

boolean doCreateTable = true;

             Statement stmt = null;

             String createString = "create table " + 

Table + 

"(SAMPLE_ID int not null generate always as increment, " + 

"KEY_ID long, " + 

"KEY_INST_COUNT int, " + 

"DATAOBJ blob (102400), " +

             "unique(KEY_ID))";

             

             try {

 

                    currentConn.setAutoCommit(false);

                    stmt = currentConn.createStatement();

                    DatabaseMetaData md = currentConn.getMetaData();

                    ResultSet rs = md.getTables(null, null, "%", null);

                    while (rs.next()) {

System.out.println("Elenco tabelle nel db " + rs.getString(3));

                           if (rs.getString(3).equals(tabella)) {

                                  doCreateTable = false;

                                  break;

                           }

                    }

                    if (doCreateTable) {

                           // execute

                           stmt.execute(createString); // I'm arriving
here ang got the error

                           doCreateTable = true;

                    }

                    currentConn.commit();

                    stmt.close();

 

             } catch (SQLException e) {

                    throw new DatabaseDriverException("Error create
table", e);

             }

             return doCreateTable;

       }/* End tableCreation */

the error is:
Syntax error: Encountered "," at line 1, column 88.

BTW, the 10.2 Reference manual talks more about BIGINT at

Re: Problem with create table in Derby 10.2.2.0

Hi Leo,

Also I think following will be a better createString, I wonder why you
didn''t get any error for "generate'. Also please don't use 'Table' as table
name. I got error for that also. And KEY_ID can not have any null values,
since you are making it unique it should be declared as not null. My
suggestion for the createString is as follows

create table Table1 (SAMPLE_ID int not null generated always as identity,KEY
_ID bigint not null,KEY_INST_COUNT int, DATAOBJ blob (102400),
unique(KEY_ID));
