    • FILTER

      public static final SqlFilterOperator FILTER
      FILTER operator filters which rows are included in an aggregate function.

    • WITHIN_GROUP

      public static final SqlWithinGroupOperator WITHIN_GROUP

    • WITHIN_DISTINCT

      public static final SqlWithinDistinctOperator WITHIN_DISTINCT
      WITHIN_DISTINCT operator performs aggregations on distinct data input.

    • CUBE

      public static final SqlInternalOperator CUBE
      CUBE operator, occurs within GROUP BY clause or nested within a GROUPING SETS.

    • GROUPING

      public static final SqlAggFunction GROUPING
      GROUPING(c1 [, c2, ...]) function.

      Occurs in similar places to an aggregate function (SELECT, HAVING clause, etc. of an aggregate query), but not technically an aggregate function.

    • GROUP_ID

      GROUP_ID() function. (Oracle-specific.)

    • GROUPING_ID

      public static final SqlAggFunction GROUPING_ID
      GROUPING_ID function is a synonym for GROUPING.

      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.

    • EXTEND

    • OVER

      public static final SqlBinaryOperator OVER
      The OVER operator, which applies an aggregate functions to a window.

      Operands are as follows:

      1. name of window function (SqlCall)
      2. window name (SqlLiteral) or window in-line specification (org.apache.calcite.sql.SqlWindow.SqlWindowOperator)

    • REINTERPRET

      public static final SqlSpecialOperator REINTERPRET
      An REINTERPRET operator is internal to the planner. When the physical storage of two types is the same, this operator may be used to reinterpret values of one type as the other. 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.

    • SUBSTRING

      public static final SqlFunction SUBSTRING
      The character substring function: SUBSTRING(string FROM start [FOR length]).

      If the length parameter is a constant, the length of the result is the minimum of the length of the input and that length. Otherwise it is the length of the input.

    • REPLACE

      public static final SqlFunction REPLACE
      The REPLACE(string, search, replace) function. Not standard SQL, but in Oracle, PostgreSQL and Microsoft SQL Server.

      REPLACE behaves a little different in Microsoft SQL Server, whose search pattern is case-insensitive during matching.

      For example, REPLACE(('ciAao', 'a', 'ciao')) returns "ciAciaoo" in both Oracle and PostgreSQL, but returns "ciciaociaoo" in Microsoft SQL Server.

    • CONVERT

      public static final SqlFunction CONVERT
      The CONVERT(charValue, srcCharsetName, destCharsetName) function converts charValue with destCharsetName, whose original encoding is specified by srcCharsetName.

      The SQL standard defines CONVERT(charValue USING transcodingName), and MySQL implements it; Calcite supports this in the following TRANSLATE function.

      MySQL and Microsoft SQL Server have a CONVERT(type, value) function; Calcite does not currently support this, either.

    • TRANSLATE

      public static final SqlFunction TRANSLATE
      The TRANSLATE/CONVERT(char_value USING transcodingName) function alters the character set of a string value from one base character set to transcodingName.

      It is defined in the SQL standard. See also the non-standard SqlLibraryOperators.TRANSLATE3, which has a different purpose.

      public static final SqlBasicFunction POWER
      The POWER(numeric, numeric) function.

    • 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.

    • EXTRACT

      The MAP Value Constructor, e.g. "MAP['washington', 1, 'obama', 44]".

    • 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

      public static final SqlInternalOperator SCALAR_QUERY
      The internal "$SCALAR_QUERY" operator returns a scalar value from a record type. It assumes the record type only has one field, and returns that field as the output.

    • STRUCT_ACCESS

      public static final SqlInternalOperator STRUCT_ACCESS
      The internal $STRUCT_ACCESS operator is used to access a field of a record.

      In contrast with DOT operator, it never appears in an SqlNode tree and allows to access fields by position and not by name.

    • TUMBLE_OLD

      public static final SqlGroupedWindowFunction TUMBLE_OLD
      The TUMBLE group function.

      This operator is named "$TUMBLE" (not "TUMBLE") because it is created directly by the parser, not by looking up an operator by name.

      Why did we add TUMBLE to the parser? Because we plan to support TUMBLE as a table function (see [CALCITE-3272]); "TUMBLE" as a name will only be used by the TUMBLE table function.

      After the TUMBLE table function is introduced, we plan to deprecate this TUMBLE group function, and in fact all group functions. See [CALCITE-3340] for details.
