Expand description

Enumerates types of optional metadata fields.

Variants§

§

SIGNEDNESS = 1

UNSIGNED flag of numeric columns.

§Value format

For each numeric column, a bit indicates whether the numeric colunm has unsigned flag. 1 means it is unsigned. The number of bytes needed for this is int((column_count + 7) / 8).

§

DEFAULT_CHARSET = 2

Character set of string columns.

This field should not appear with COLUMN_CHARSET.

§Value format

  • default charset as a lenght-encoded integer,
  • then for every character column which charset isn’t default:
    • column index as a lenght-encoded integer,
    • column charset as a length-encoded integer.

The order is the same as the order of column_type field.

§

COLUMN_CHARSET = 3

Character set of string columns.

This field should not appear with DEFAULT_CHARSET.

§Value format

  • for every character column:
    • column charset as a length-encoded integer.

The order is the same as the order of column_type field.

§

COLUMN_NAME = 4

Collumn name of columns (included if binlog_row_metadata=FULL).

§Value format

  • for every column:
    • column name as a length-encoded string.

The order is the same as the order of column_type field.

§

SET_STR_VALUE = 5

Name of each variant in a SET columns.

§Value format

  • for every SET column:
    • number of variants as a length-encoded integer,
    • for each variant:
      • name of a variant as a length-encoded string.

The order is the same as the order of column_type field.

§

ENUM_STR_VALUE = 6

Name of each variant in an ENUM columns.

§Value format

  • for every ENUM column:
    • number of variants as a length-encoded integer,
    • for each variant:
      • name of a variant as a length-encoded string.

The order is the same as the order of column_type field.

§

GEOMETRY_TYPE = 7

Real type of geometry columns.

§Value format

  • for every geometry column:
    • geometry type as a length-encoded integer.

The order is the same as the order of column_type field.

§

SIMPLE_PRIMARY_KEY = 8

Primary key without prefix (included if binlog_row_metadata=FULL).

This field should not appear with PRIMARY_KEY_WITH_PREFIX.

§Value format

  • for every PK index column:
    • column index as a length-encoded integer.

The order is the same as the order of column_type field.

§

PRIMARY_KEY_WITH_PREFIX = 9

Primary key with prefix (included if binlog_row_metadata=FULL).

This field should not appear with SIMPLE_PRIMARY_KEY.

§Value format

  • for every PK index column:
    • column index as a length-encoded integer,
    • prefix length as a length-encoded integer

The order is the same as the order of column_type field.

§Note
  • prefix length is a character length, i.e. prefix byte length divided by the maximum length of a character in the correspoding charset;
  • prefix length 0 means that the whole column value is used.
§

ENUM_AND_SET_DEFAULT_CHARSET = 10

Character set of enum and set columns.

This field should not appear with ENUM_AND_SET_COLUMN_CHARSET.

§Value format

  • default charset as a lenght-encoded integer,
  • then for every SET or ENUM column which charset isn’t default:
    • column index as a lenght-encoded integer,
    • column charset as a length-encoded integer.

The order is the same as the order of column_type field.

§

ENUM_AND_SET_COLUMN_CHARSET = 11

Character set of enum and set columns.

This field should not appear with ENUM_AND_SET_DEFAULT_CHARSET.

§Value format

  • for every SET or ENUM column:
    • column charset as a length-encoded integer.

The order is the same as the order of column_type field.

§

COLUMN_VISIBILITY = 12

A flag that indicates column visibility attribute.
