AggregateNode

public AggregateNode()

方法详细资料

getSQLFunction

public SQLFunction getSQLFunction()

指定者:

getSQLFunction 在接口中 FunctionNode

resolve

public void resolve()

getFirstArgumentType

public Type getFirstArgumentType()

指定者:

getFirstArgumentType 在接口中 FunctionNode

getDataType

public Type getDataType()

从接口复制的说明: SelectExpression

Returns the data type of the select expression.

指定者:

getDataType 在接口中 SelectExpression

覆盖:

getDataType 在类中 SqlNode

返回:

The data type of the select expression.

setScalarColumnText

public void setScalarColumnText(int i)
                         throws antlr.SemanticException

从接口复制的说明: SelectExpression

Appends AST nodes that represent the columns after the current AST node. (e.g. 'as col0_O_')

指定者:

setScalarColumnText 在接口中 SelectExpression

参数:

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

抛出:

antlr.SemanticException - if a semantic error occurs

isScalar

public boolean isScalar()
                 throws antlr.SemanticException

指定者:

isScalar 在接口中 SelectExpression

覆盖:

isScalar 在类中 AbstractSelectExpression

抛出:

antlr.SemanticException
