Member Data Documentation

uint st_field_info::field_flags

This is used to set column attributes. By default, columns are NOT NULL and SIGNED, and you can deviate from the default by setting the appopriate flags. You can use either one of the flags MY_I_S_MAYBE_NULL and or combine them using the bitwise or operator |. Both flags are defined in table.h.

uint st_field_info::field_length

For string-type columns, this is the maximum number of characters. Otherwise, it is the 'display-length' for the column.

const char* st_field_info::field_name

This is used as column name.

enum enum_field_types st_field_info::field_type

This denotes data type for the column. For the most part, there seems to be one entry in the enum for each SQL data type, although there seem to be a number of additional entries in the enum.

uint st_field_info::open_method

This should be one of SKIP_OPEN_TABLE, OPEN_FRM_ONLY or OPEN_FULL_TABLE.
