构造器详细资料

StaticPrecisionFspTimestampFunction

public StaticPrecisionFspTimestampFunction(String name,
                                           boolean hasParenthesesIfNoArguments)

Constructs a StandardBasicTypes.TIMESTAMP function using the default fractional second precision as defined by the database.

参数:

name - The function name

hasParenthesesIfNoArguments - Does the function call need parenthesis if there are no arguments?

StaticPrecisionFspTimestampFunction

public StaticPrecisionFspTimestampFunction(String name,
                                           int fsp)

Constructs a StandardBasicTypes.TIMESTAMP function using the specified fractional seconds precision.

参数:

name - The function name

fsp - The explicit fractional seconds precision to render

抛出:

IllegalArgumentException - if fsp < 0.

方法详细资料

render

public String render(Type argumentType,
                     List args,
                     SessionFactoryImplementor factory)
              throws QueryException

从接口复制的说明: SQLFunction

Render the function call as SQL fragment.

Note, the 'firstArgumentType' parameter should match the one passed into SQLFunction.getReturnType(org.hibernate.type.Type, org.hibernate.engine.spi.Mapping)

指定者:

render 在接口中 SQLFunction

覆盖:

render 在类中 NoArgSQLFunction

参数:

argumentType - The type of the first argument

args - The function arguments

factory - The SessionFactory

返回:

The rendered function call

抛出:

QueryException - Indicates a problem rendering the function call.
