data conversion
Topic by mensssanvi
3 weeks ago
This field Resid_Mat is rounding to to 2 decimal places, thus having an effect on the Num_payment field calculation as per attached sql. Does anyone know how I can remedy this? Any help will be much appreciated.
An example of Resid_Mat by running the sql gives me 2.32 instead of 2.31895961670089.

sql, numeric to date, decimal to date
Hi there...
I'm pretty nobbish in this type of SQL so please try not to be rough for me :)
Well.. I have to convert numeric field to date, than count some upload data and group by table.
Numeric_column like 20121121133549 which is probably like YYYYMMDDHHMMSS
Other columns are acces_point_type and data_uplink.

What is a building block approach to building semantic data models?
Topic by egetts
02 Dec 2011
The idea is that modeling constructs could be pre-defined and developed to promote rapid time to value, design flexibility, data consistency, and user-friendliness. These building blocks could be collected into libraries, customized, and reused.
