Subject [jira] Commented: (DERBY-785) Cannot specify default value for DECIMAL(15,15) column
Date Sun, 25 Dec 2005 14:42:32 GMT
    [ http://issues.apache.org/jira/browse/DERBY-785?page=comments#action_12361224 ] 

Thomas Dudziak commented on DERBY-785:
--------------------------------------

Ups, sorry, my bad. Obviously I cannot specify a default value here with a something other
than 0 before the fixed point. I would mark this issue invalid if I could ;-)
Btw. for some reason this works:

CREATE TABLE test
(
    pk INTEGER NOT NULL,
    value NUMERIC(15,15) DEFAULT 1 NOT NULL,
    PRIMARY KEY (pk)
);

Also, if I try to insert something into this column, say:

        PreparedStatement pstmt = conn.prepareStatement("INSERT INTO test (pk, value) VALUEs
(?, ?)");

        pstmt.setInt(1, 1);
        pstmt.setBigDecimal(2, new BigDecimal("1"));

        pstmt.execute();


then I get this exception (which is somewhat misleading):

Exception in thread "main" org.apache.derby.client.am.SqlException: BigDecimal conversion
exception [converters] Overflow occurred during numeric data type conversion of "1".. See
attached Throwable.

> CREATE TABLE test
> (
>     pk INTEGER NOT NULL,
>     value DECIMAL(15,14) DEFAULT 1.0 NOT NULL,
>     PRIMARY KEY ("PK")
> );
> The same holds true for a NUMERIC column.
