Mamta A. Satoor commented on DERBY-5407:
----------------------------------------

I have committed the changes to top fo the trunk. Will migrate it to earlier releases(sounds
like upto 10.6 but I will verify while migrating it.)

> In private correspondence, Mani Afschar Yazdi reports that dblook omits the length specification
for VARCHAR FOR BIT DATA columns when run across the network. Embedded dblook runs fine. I
can reproduce this problem as follows:
> 1) Bring up a server (here I am using port 8246).
> 2) Create a database with the following ij script:
> connect 'jdbc:derby://localhost:8246/memory:db;create=true';
> create table t( a varchar( 20 ) for bit data );
> 3) Now run dblook across the network:
> java -org.apache.derby.tools.dblook -d "jdbc:derby://localhost:8246/memory:db"
> This produces the following DDL for the table:
> CREATE TABLE "APP"."T" ("A" VARCHAR () FOR BIT DATA);
> A similar experiment using an embedded database produces usable DDL which includes a
length specification for the VARCHAR FOR BIT DATA column.
