OpenAccess SDK SQL Engine core methods for Java : Exchanging data : Custom scalar functions
 

Custom scalar functions

Custom scalar functions are an extension of scalar functions that are used only in a search condition (WHERE clause). OpenAccess SDK enables the IP to obtain details of the custom scalar conditions and to handle their evaluation. OpenAccess SDK then transforms the custom conditions into a set of AND conditions and returns each set as a list. Each list can contain one or more conditions as OR predicates.
Your IP must perform a sequence of operations to handle the evaluation of custom scalar functions in WHERE clause. See Using Custom Scalar Functions in a WHERE Clause for more information.
