Loading only values of a particular attribute value

[aditya]

All,

I have a job which works like this

SequentialFile --> Transformer --> HashFile

I have some attributes in the seq. file and I want to do a select on those attributes where attribute_value = 'XXXX'. I tried specifiying this condition as a constraint in the transformer where mention attribute_value='xxx' but the hashfiles continues to be populated with all the data from the sequential file.

Could some on help me on this

Thnx.

Aditya.

aditya,

the method you described is the normal way of filtering data. Perhaps you have a syntax error or similar error in your constraint. Most likely your "attribute_value" is specified incorrectly, you can check that and perhaps post your exact constraint to this thread.

That suggests that every row in the sequential file satisfies your condition, or that you have mistyped the constraint expression.

Can you check the latter?

Use the Debugger to step through a row at a time, inspecting (watching) the values of the attribute(s) as you step through. Set a breakpoint to pause when the condition is not met.

Did you clear the hash file before load?

I faced this issue once. What i did was that i assigned the logic to the particular column instead of putting it as a stage vairable/constraint. It worked...
