String types

Updated at:

PolarDB-X 1.0 supports the MySQL 5.7 string data types. Use these types to store character strings, binary strings, and enumerated values.

Supported types

Type Description
CHAR and VARCHAR Fixed-length and variable-length character strings.
BINARY and VARBINARY Fixed-length and variable-length binary strings, similar to CHAR and VARCHAR but storing raw bytes rather than characters.
BLOB and TEXT Large-object types for binary data (BLOB) and character data (TEXT).
ENUM A string with a value chosen from a predefined list.
SET A string that can hold zero or more values from a predefined list.

For full syntax, storage requirements, and character set interactions, see String data types in the MySQL 5.7 Reference Manual.
