Member Data Documentation

◆ default_value

Item* sp_variable::default_value

Default value of the SP-variable (if any).

◆ field_def

Create_field sp_variable::field_def

Full type information (field meta-data) of the SP-variable.

◆ mode

enum_mode sp_variable::mode

Mode of the SP-variable.

◆ name

LEX_STRING sp_variable::name

Name of the SP-variable.

◆ offset

uint sp_variable::offset

The index to the variable's value in the runtime frame.

It is calculated during parsing and used when creating sp_instr_set instructions and Item_splocal items. I.e. values are set/referred by array indexing in runtime.

◆ type

enum enum_field_types sp_variable::type

Field-type of the SP-variable.
