Detailed Description

class to copying an field/item to a key struct

Definition at line 1132 of file sql_select.h.

Member Function Documentation

enum store_key_result store_key::copy ( )

inline

sets ignore truncation warnings mode and calls the real copy method

this function makes sure truncation warnings when preparing the key buffers don't end up as errors (because of an enclosing INSERT/UPDATE).

Definition at line 1165 of file sql_select.h.

Here is the caller graph for this function:

virtual const char* store_key::name ( ) const

pure virtual

Not actually needed

Implemented in store_key_const_item, store_key_item, and store_key_field.
