Constructor Detail

StaticPrecisionFspTimestampFunction

public StaticPrecisionFspTimestampFunction(String name,
                                           boolean hasParenthesesIfNoArguments)

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

Parameters:

name - The function name

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

StaticPrecisionFspTimestampFunction

public StaticPrecisionFspTimestampFunction(String name,
                                           int fsp)

Parameters:

name - The function name

fsp - The explicit fractional seconds precision to render

Throws:

IllegalArgumentException - if fsp < 0.

Method Detail

render

public String render(Type argumentType,
                     List args,

Overrides:

render in class NoArgSQLFunction

Parameters:

argumentType - The type of the first argument

args - The function arguments

factory - The SessionFactory

Returns:

The rendered function call

Throws:

QueryException - Indicates a problem rendering the function call.
