[ http://issues.apache.org/jira/browse/DERBY-437?page=all ]
Suresh Thalamati updated DERBY-437:
-----------------------------------
Attachment: derby437.diff
Currently for compress procedure to work incase of case-sensitive table name ,
schema names, they needs to be passed in quotes like ( call
SYSCS_UTIL.SYSCS_COMPRESS_TABLE('APP' , '"Order"' ,1) ;). This behaviour is
not consitent with other procedures and the docs.
This patch makes compress procedure parameters for table names , schema name
should be passed in the case-sensitive form if they are quoted identfiers and
in upper case if they are not quoted SQL identifiers, similar to other system
procedures. Compress procedure generates ALTER COMPRESS statement.with
quoted table name and schema name.
Ran derbyall suite , all tests passed.
> SYSCS_UTIL.SYSCS_COMPRESS_TABLE does not work on tables that are created
> with delimited identifier names.

> COMPRESS_TABLE procedure forms SQL statement undeneath, so if the user does
> not pass quoted names , it is not working with delimited table/schema names..
> eg: create table "Order"(a int ) ;
> ij> call SYSCS_UTIL.SYSCS_COMPRESS_TABLE('APP' , 'Order' ,1) ;
> ERROR 38000: The exception 'SQL Exception: Syntax error: Encountered "Order"
> at
> line 1, column 17.' was thrown while evaluating an expression.
> ERROR 42X01: Syntax error: Encountered "Order" at line 1, column 17.
> With quoted names it works fine.
> ij> call SYSCS_UTIL.SYSCS_COMPRESS_TABLE('APP' , '"Order"' ,1) ;
> 0 rows inserted/updated/deleted
> If it is expected that user to pass quoted names for
> SYSCS_UTIL.SYSCS_COMPRESS_TABLE, then it is ok.
> But doc is not clear:
> COMPRESS_TABLE doc in the reference manual:
> TABLENAME
> An input argument of type VARCHAR(128) that specifies the table name
> of the table. The string must exactly match the case of the table
> name, and the argument of "Fred" will be passed to SQL as the
> delimited identifier 'Fred'. Passing a null will result in an error.
> So either doc has to be fixed or code needs to be fixed to handle quoted
> names for compress table.
> I think the code has to fixed to be consistent with other system procedures.
> . i.e
> If you created a schema, table or column name as a non-delimited identifier,
> you must pass the name in all upper case. If you created a schema, table or
> column name as a delimited identifier, you must pass the name in the same
> case as it was created.
> For example:
> create table "Order"(a int ) ;
> call SYSCS_UTIL.SYSCS_COMPRESS_TABLE('APP' , 'Order' ,1) ;
> create table t1( a int )
> call SYSCS_UTIL.SYSCS_COMPRESS_TABLE('APP' , 'T1' ,1) ;
