Subject [jira] Updated: (DERBY-437) SYSCS_UTIL.SYSCS_COMPRESS_TABLE does not work on tables that are created with delimited identifier names.
Date Sat, 09 Jul 2005 01:03:10 GMT
     [ 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.

> 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) ;
