extractDataType

protected Type extractDataType(Node operand)

getDataType

public Type getDataType()

Description copied from interface: OperatorNode

Retrieves the data type for the overall operator expression.

Specified by:

getDataType in interface OperatorNode

Specified by:

getDataType in interface SelectExpression

Overrides:

getDataType in class SqlNode

Returns:

The expression's data type.

getLeftHandOperand

public Node getLeftHandOperand()

Retrieves the left-hand operand of the operator.

Specified by:

getLeftHandOperand in interface BinaryOperatorNode

Returns:

Specified by:

setScalarColumnText in interface SelectExpression

Parameters:

i - The index of the select expression in the projection list.

Throws:

antlr.SemanticException - if a semantic error occurs
