I want to know if the fast bcp works for a table that has triggers disables, or do I have to remove the triggers?
According to the Sybase doc, on ASE15.0, disabling the trigger won't help bcp to use the fast mode: http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.help.ase_15.0.utility/html/utility/utility62.htm
=> If space is available, you can use drop index and drop trigger to drop all the indexes and triggers beforehand.
in ASE15.7 ESD#3, the doc seems to indicate that the triggers are not a problem for fast-bcp: http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc30191.1573/html/utilityguide/utilityguide63.htm
To be tested...
