Dear all, My test application want to implement two application interface over MonetDB , one is loading *.csv file to MonetDB, to implement this interface ,I use MonetDB's JDBC and "copy from" command to implement it. and another interface is select from one bat using select conditions, such as this C function: bat *selectfrombat(char * batname,char * select condition), how do I implement it?do MonetDB has something like "copy from " command,and so I will use jdbc and the command to implement it? or other method to implement it? I know one MAL instruction is algebra.uselect, and corresponding C function, do I just use the C function or alter the C fuction? Best regards,
