Date Fri, 29 Jun 2012 20:27:43 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13404176#comment-13404176
] 

Mamta A. Satoor commented on DERBY-5750:
----------------------------------------

Knut, I just committed a patch for this jira after taking care of of your comments.

The commit comments are as follows
*********************************
DERBY-5750 Sending an empty string as table name to compress table procedure or empty string
as index name to update statistics procedure makes the parser throw an exception. 

Committing changes for DERBY-5750 which will provide following functionality 
a)if schema name is provided as an empty string, we will throw SQLState.LANG_SCHEMA_DOES_NOT_EXIST
b)if table name is provided as an empty string, we will throw SQLState.LANG_TABLE_NOT_FOUND
c)if index name is provided as an empty string(this is for update and drop statistics procedures),
we will throw 
	SQLState.LANG_INDEX_NOT_FOUND
d)if schema name is null, we will use current schema to resolve the table name
e)if table name is null, we will throw SQLState.LANG_TABLE_NOT_FOUND
f)if index name is null, we will drop/update statisitcs for all the indexes for the given
table.

I have added few test cases for each of these procedures.

> When empty string is passed for the index name to the update statistics procedure, it
throws following exception(passing an empty string for table to compress table procedure also
gives simiar exception). The new stored procedure being created through DERBY-4115 for dropping
the statistics also gave similar exception
