Which of the Following Data Types Are Not Supported By Value Comparison?

DRS data comparison allows you to check whether the data in the source database is the same as that in the destination database.

DRS does not support value comparison for the data types shown here. During value comparison, these data types are automatically ignored.

**Table 1** Data types that do not support value comparison
Source DB Type	Data Type
MySQL	TINYBLOB, BLOB, MEDIUMBLOB, LONGBLOB, TINYTEXT, TEXT, MEDIUMTEXT, LONGTEXT Note: These types support value comparison after synchronization from MySQL to MySQL, and MySQL to GaussDB Centralized.
GaussDB	TEXT, CLOB, BLOB, BYTEA, INTERVAL DAY TO SECOND, INTERVAL Note: These types support value comparison after synchronization from GaussDB Distributed to GaussDB Distributed, and GaussDB Centralized to MySQL.
MongoDB	_id is of the BINDATA type.

DRS does not support value comparison for the following primary key types. During value comparison, the following primary key types are grouped into a specified table that does not support comparison.

**Table 2** Primary key type that does not support value comparison.
Source DB Type	Data Type
GaussDB	TEXT, CLOB, BLOB, BYTEA, INTERVAL DAY TO SECOND, INTERVAL, REAL, DOUBLE PRECISION, BOOL, TIME, TIMETZ, TIMESTAMP, TIMESTAMPTZ, DATE Note: During comparison after synchronization from GaussDB Distributed to GaussDB Distributed, or GaussDB Centralized to MySQL, if a primary key type that does not support value comparison is used as a composite primary key and the composite primary key contains the primary key type that supports value comparison, value comparison can be performed by primary key table.
PostgreSQL	REAL, DOUBLE PRECISION, MONEY, TEXT, BYTEA, TIMESTAMP WITHOUT TIME ZONE, TIMESTAMP WITH TIME ZONE, DATE, TIME WITHOUT TIME ZONE, TIME WITH TIME ZONE, INTERVAL, BOOLEAN, ENUMERATED TYPES, POINT, LINE, LSEG, BOX, PATH, POLYGON, CIRCLE, CIDR, INET, MACADDR, MACADDR8, BIT, BIT VARYING, TSVECTOR, TSQUERY, XML, JSON, ARRAY, COMPOSITE TYPES, INT4RANGE, INT8RANGE, NUMRANGE, TSRANGE, TSTZRANGE, DATERANGE
