 MemberDescription
ColumnDefinition
(Optional) The SQL fragment that is used when generating the DDL for the column. Defaults to the generated SQL to create a column of the inferred type.
Insertable
(Optional) Whether the column is included in SQL INSERT statements generated by the persistence provider.
Length
(Optional) The column length. (Applies only if a string-valued column is used.)
Name
(Optional) The name of the column. Defaults to the property or field name.
Nullable
(Optional) Whether the database column is nullable.
Precision
(Optional) The precision for a decimal (exact numeric) column. (Applies only if a decimal column is used.) Value must be set by developer if used when generating the DDL for the column.
Scale
(Optional) The scale for a decimal (exact numeric) column. (Applies only if a decimal column is used.)
Table
(Optional) The name of the table that contains the column. If absent the column is assumed to be in the primary table.
Unique
(Optional) Whether the column is a unique key. This is a shortcut for the UniqueConstraint annotation at the table level and is useful for when the unique key constraint corresponds to only a single column. This constraint applies in addition to any constraint entailed by primary key mapping and to constraints specified at the table level.
Updatable
(Optional) Whether the column is included in SQL UPDATE statements generated by the persistence provider.
