Data type of the column.

To help make scripts database-independent, Liquibase automatically converts the following generic data types to the correct database implementation: BIGINT, BLOB, BOOLEAN, CHAR, CLOB, CURRENCY, DATE, DATETIME, DECIMAL, DOUBLE, FLOAT, INT, MEDIUMINT, NCHAR, NUMBER, NVARCHAR, SMALLINT, TIME, TIMESTAMP, TINYINT, UUID, VARCHAR, XML.

Also, specifying a java.sql.Types.* type is converted to the correct type as well. For example:

  • java.sql.Types.TIMESTAMP
  • java.sql.Types.VARCHAR(255)
mysql   4.3 (for XML)
columnParentType Indicates the parent object type of the column we are setting remarks against. Valid values are VIEW and TABLE. Default: TABLE.
