-----------------------------------
Summary: Follow up TRAFODION-1858 , need a better fix
Key: TRAFODION-1881
URL: https://issues.apache.org/jira/browse/TRAFODION-1881
Project: Apache Trafodion
Issue Type: Bug
Reporter: liu ming
TRAFODION-1858 is now fixed using a temp method. A better and complete solution
is required.
But to solve it entirely, it requires a more throughout refactor of many
related parts of code.
It is a real customer blocking issue, so we fix it with the temp solution and
using this JIRA to follow up.
The solution in TRAFODION-1858 is to add a new method to check the string name
of a given column to tell if it is SALT column, or DIVSION column. The checking
method is hardcoding the naming conversion, which may change and break the
function.
However, to use NAColumn's built-in helper checking methods, it needs the SQL
compiler to generate correct constraint info from begining and change all the
intermediate objects along the path. It may also need to change the METATABLE
which contains information about constraints.
So we use this JIRA to track, and need a longer time to find a good solution to
solve TRAFODION-1858.
