public class TTableHint
extends TParseTreeNode

SQL Server table hint:

Syntax 1:

    WITH  ( <table_hint> [ [, ]...n ] )

    <table_hint> ::=  FORCESCAN
    use getHint() method get this hint:FORCESCAN

    <table_hint> ::= INDEX =  ( index_value )
    isIndex() return true, getHint() return index_value.

    <table_hint> ::= INDEX  ( index_value [ ,...n ] )
    isIndex() return true, getExprList() return index_value list.
