>             Project: Derby

> I create a test table with the following query:
> CREATE TABLE "DERBYTEST" ("STRINGCOLUMN" varchar(255), "INTEGERCOLUMN" integer, "SHORTCOLUMN"
varchar(255), "LONGCOLUMN" bigint, "DOUBLECOLUMN" double, "FLOATCOLUMN" double, "DECIMALCOLUMN"
decimal(31, 6), "BOOLEANCOLUMN" smallint, "DATECOLUMN" timestamp, "DATETIMECOLUMN" timestamp,
"ID" integer, "LASTMODTIME" timestamp, PRIMARY KEY ("ID"))
> this query completes successfully
> I later try to copy the table with the following query:
> CREATE TABLE "DERBYTEST_TEMP" AS SELECT * FROM DERBYTEST WITH NO DATA
> This throws the following exception:
> [42X71][30000] Invalid data type 'DECIMAL(31, 6)' for column 'DECIMALCOLUMN'
> Everything works perfectly fine if I remove the decimal column.
