Cannot create CHAR column with size greater than 254
----------------------------------------------------
Key: DERBY-52
URL: http://issues.apache.org/jira/browse/DERBY-52
Project: Derby
Type: Bug
Components: SQL
Versions: 10.0.2.0
Environment: Dell Dimension 2350, 2GHz P4, 1 Gig RAM,
Window XP Pro Version 2002, SP2
JDK 1.4.2_03, build 1.4.2_03-b02
Derby Snapshot SVN version 46005 (Binaries)
Reporter: Jason Palmatier
An attempt to create a table that contains a column of type CHAR with a size
greater than 254 using the SQL statement
CREATE TABLE dummyTable ( column1 char(255),column2 char(10),column3 char(10) )
results in the following SQL Exception:
SQL Exception: The length, precision, or scale attribute for column, or type
mapping 'CHAR(255)' is not valid.
SQL Error: 30000
SQL State: 42611
However, if you decrease column1's length by one as below, the table is created
successfully:
CREATE TABLE dummyTable ( column1 char(254),column2 char(10),column3 char(10) )
The Derby Reference Manual states that the limit on the length of a CHAR data
type is java.lang.Integer.MAX_VALUE:
