Numeric types are mapped to appropriate database types depending on the platform.


By default BigDecimal maps to database decimal(16,3). This default can be changed via databaseConfig.addCustomMapping():

// set the default mapping for BigDecimal.class/decimal
databaseConfig.addCustomMapping(DbType.DECIMAL, "decimal(8,2)");

Decimal precision and scale

Explicitly specify decimal precision and scale using @Column.

@Column(precision = 10, scale = 4)
BigDecimal approvalRate;

primitive types

Primitive types are deemed non nullable. Ebean will generate DDL for these as not nullable.

// primitive type deemed non nullable
long approvalTotal;
