    Some history. The GROUPING function is in the SQL standard, and originally supported only one argument. GROUPING_ID is not standard (though supported in Oracle and SQL Server) and supports one or more arguments.
    The SQL standard has changed to allow GROUPING to have multiple arguments. It is now equivalent to GROUPING_ID, so we made GROUPING_ID a synonym for GROUPING.

This operator is similar to a cast, except that it does not alter the data value. Like a regular cast it accepts one operand and stores the target type as the return type. It performs an overflow check if it has any second operand, whether true or not.

  - CAST
```
public static final SqlFunction CAST
```
    The SQL CAST operator.
    The SQL syntax is
    CAST(expression AS type)
    
    When the CAST operator is applies as a SqlCall, it has two arguments: the expression and the type. The type must not include a constraint, so CAST(x AS INTEGER NOT NULL), for instance, is invalid.
    
    When the CAST operator is applied as a RexCall, the target type is simply stored as the return type, not an explicit operand. For example, the expression CAST(1 + 2 AS DOUBLE) will become a call to CAST with the expression 1 + 2 as its only operand.
    
    The RexCall form can also have a type which contains a NOT NULL constraint. When this expression is implemented, if the value is NULL, an exception will be thrown.

```
public static final SqlOperator ITEM
```

  - SLICE
```
public static final SqlInternalOperator SLICE
```
    The internal "$SLICE" operator takes a multiset of records and returns a multiset of the first column of those records.
    It is introduced when multisets of scalar types are created, in order to keep types consistent. For example, MULTISET [5] has type INTEGER MULTISET but is translated to an expression of type RECORD(INTEGER EXPR$0) MULTISET because in our internal representation of multisets, every element must be a record. Applying the "$SLICE" operator to this result converts the type back to an INTEGER MULTISET multiset value.
    $SLICE is often translated away when the multiset type is converted back to scalar values.
  - ELEMENT_SLICE
```
public static final SqlInternalOperator ELEMENT_SLICE
```
    The internal "$ELEMENT_SLICE" operator returns the first field of the only element of a multiset.
    It is introduced when multisets of scalar types are created, in order to keep types consistent. For example, ELEMENT(MULTISET [5]) is translated to $ELEMENT_SLICE(MULTISET (VALUES ROW (5 EXPR$0)) It is translated away when the multiset type is converted back to scalar values.
    
    NOTE: jhyde, 2006/1/9: Usages of this operator are commented out, but I'm not deleting the operator, because some multiset tests are disabled, and we may need this operator to get them working!
  - SCALAR_QUERY

  - PATTERN_ALTER
```
public static final SqlBinaryOperator PATTERN_ALTER
```
    | operator to create alternate patterns within MATCH_RECOGNIZE.
    If p1 and p2 are patterns then p1 | p2 is a pattern that matches p1 or p2.
  - PATTERN_CONCAT
```
public static final SqlBinaryOperator PATTERN_CONCAT
```
    Operator to concatenate patterns within MATCH_RECOGNIZE.
    If p1 and p2 are patterns then p1 p2 is a pattern that matches p1 followed by p2.
  - PATTERN_QUANTIFIER
```
public static final SqlSpecialOperator PATTERN_QUANTIFIER
```
    Operator to quantify patterns within MATCH_RECOGNIZE.
    If p is a pattern then p{3, 5} is a pattern that matches between 3 and 5 occurrences of p.
  - PATTERN_PERMUTE
```
public static final SqlSpecialOperator PATTERN_PERMUTE
```
    PERMUTE operator to combine patterns within MATCH_RECOGNIZE.
    If p1 and p2 are patterns then PERMUTE (p1, p2) is a pattern that matches all permutations of p1 and p2.
  - PATTERN_EXCLUDE
```
public static final SqlSpecialOperator PATTERN_EXCLUDE
```
    EXCLUDE operator within MATCH_RECOGNIZE.
    If p is a pattern then {- p -} } is a pattern that excludes p from the output.

```
public SqlStdOperatorTable()
```
- Method Detail
  - instance
```
public static SqlStdOperatorTable instance()
```
    Returns the standard operator table, creating it if necessary.
  - auxiliaryToGroup
```
public static SqlGroupedWindowFunction auxiliaryToGroup(SqlKind kind)
```
    Returns the group function for which a given kind is an auxiliary function, or null if it is not an auxiliary function.
  - convertAuxiliaryToGroupCall
```
public static SqlCall convertAuxiliaryToGroupCall(SqlCall call)
```
    Converts a call to a grouped auxiliary function to a call to the grouped window function. For other calls returns null.
    For example, converts TUMBLE_START(rowtime, INTERVAL '1' HOUR)) to TUMBLE(rowtime, INTERVAL '1' HOUR)).
  - convertGroupToAuxiliaryCalls
```
public static List<Pair<SqlNode,AuxiliaryConverter>> convertGroupToAuxiliaryCalls(SqlCall call)
```
    Converts a call to a grouped window function to a call to its auxiliary window function(s). For other calls returns null.
    For example, converts TUMBLE_START(rowtime, INTERVAL '1' HOUR)) to TUMBLE(rowtime, INTERVAL '1' HOUR)).
  - copy
```
private static SqlCall copy(SqlCall call,
                            SqlOperator operator)
```
    Creates a copy of a call with a new operator.
  - some
```
public static SqlQuantifyOperator some(SqlKind comparisonKind)
```
    Returns the operator for SOME comparisonKind.
  - all
```
public static SqlQuantifyOperator all(SqlKind comparisonKind)
```
    Returns the operator for ALL comparisonKind.
