Method Details

getKind

public SqlKind getKind()

Description copied from class: SqlNode

Returns the type of node this is, or SqlKind.OTHER if it's nothing special.

Overrides:

getKind in class SqlCall

Returns:

a SqlKind value, never null

See Also:

• SqlNode.isA(java.util.Set<org.apache.calcite.sql.SqlKind>)

getOperator

public SqlOperator getOperator()

Specified by:

getOperator in class SqlCall

getOperandList

public List<SqlNode> getOperandList()

Description copied from class: SqlCall

Returns the list of operands. The set and order of operands is call-specific.

Note: the proper type would be List<@Nullable SqlNode>, however, it would trigger too many changes to the current codebase.

Specified by:

getOperandList in class SqlCall

Returns:

the list of call operands, never null, the operands can be null

setOperand

public void setOperand(int i,
 @Nullable SqlNode operand)

Description copied from class: SqlCall

Changes the value of an operand. Allows some rewrite by SqlValidator; use sparingly.

Overrides:

setOperand in class SqlCall

Parameters:

i - Operand index

operand - Operand value

validate

public void validate(SqlValidator validator,
 SqlValidatorScope scope)

Description copied from class: SqlCall

Validates this call.

The default implementation delegates the validation to the operator's SqlOperator.validateCall(org.apache.calcite.sql.SqlCall, org.apache.calcite.sql.validate.SqlValidator, org.apache.calcite.sql.validate.SqlValidatorScope, org.apache.calcite.sql.validate.SqlValidatorScope). Derived classes may override (as do, for example SqlSelect and SqlUpdate).

Overrides:

validate in class SqlCall

Parameters:

scope - Validator
