Common MySQL and Lease Data Methods.

The MySqlLease4Exchange and MySqlLease6Exchange classes provide the functionality to set up binding information between variables in the program and data extracted from the database. This class is the common base to both of them, containing some common methods.

Member Function Documentation

getColumnsInError()

static std::string isc::dhcp::MySqlLeaseExchange::getColumnsInError ( my_bool *  error, std::string *  names, size_t  count  )

inlinestatic

Return columns in error.

If an error is returned from a fetch (in particular, a truncated status), this method can be called to get the names of the fields in error. It returns a string comprising the names of the fields separated by commas. In the case of there being no error indicators set, it returns the string "(None)".

Parameters

error	Array of error elements. An element is set to MLM_TRUE if the corresponding column in the database is the source of the error.
names	Array of column names, the same size as the error array.
count	Size of each of the arrays.

setErrorIndicators()

static void isc::dhcp::MySqlLeaseExchange::setErrorIndicators ( MYSQL_BIND *  bind, my_bool *  error, size_t  count  )

inlinestatic

Set error indicators.

Sets the error indicator for each of the MYSQL_BIND elements. It points the "error" field within an element of the input array to the corresponding element of the passed error array.

Parameters

bind	Array of BIND elements
error	Array of error elements. If there is an error in getting data associated with one of the "bind" elements, the corresponding element in the error array is set to MLM_TRUE.
count	Size of each of the arrays.
