ChoicesSpecializedSqlScalarFunction

public ChoicesSpecializedSqlScalarFunction(BoundSignature boundSignature,
 List<ChoicesSpecializedSqlScalarFunction.ScalarImplementationChoice> choices)

Creates a ScalarFunctionImplementation consisting of one or more choices.

All choices must have the same SQL signature, and are equivalent in what they do. The first choice is the default choice, which is the one used for legacy access methods. The default choice must be usable under any context. (e.g. it must not use BLOCK_POSITION convention.)

Parameters:

choices - the list of choices, ordered from generic to specific
