Detailed Description

Instances of the class IldArgument describe the arguments of a stored procedure or function.

Library: dbkernel

Since these arguments differ from a column description only by the input and output states and by the existence of a default value, the class is derived from the basic descriptor class IldDescriptor.

IlBoolean IldArgument::hasDefault

(

)

const

Indicate whether the argument has a default value and can thus be omitted in a call to the stored procedure to which it belongs.

Note

The default value is not stored in the description.

IlBoolean IldArgument::isInArgument

(

)

const

Indicate whether the argument is an input argument.

Note

This function return value is not the opposite of the one from the function isOutArgument().

IlBoolean IldArgument::isInOutArgument

(

)

const

Indicate whether the argument is used both on input and on output.

Note

Sensibly, if the argument is an in-out argument, then both functions isInArgument() and isOutArgument() will return IlTrue.

IlBoolean IldArgument::isOutArgument

(

)

const

Indicate whether the argument is an output argument.

Note

This function return value is not the opposite of the one from the function isInArgument().
