Rick Hillegas updated DERBY-6956:
---------------------------------
Attachment: derby-6956-01-aa-removeSpuriousCheck.diff
Attaching derby-6956-01-aa-removeSpuriousCheck.diff. This patch removes the
offending extra check for maximum width. Tests passed cleanly against this
patch.
Thanks for digging into the code, Bryan. I think that the extra check is just a
mistake. The datatype rejected by CREATE TABLE AS SELECT is exactly the same
datatype which was used by CREATE TABLE. The remaining checks for DECIMAL look
adequate to me.
I am inclined to commit this patch.
> Create table as Select cannot copy Decimal columns

> 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.
