A representation of the model object 'Domain'. 4.12 Domains A domain is a set of permissible values. A domain is defined in a schema and is identified by a . The purpose of a domain is to constrain the set of valid values that can be stored in a column of a base table by various operations. A domain definition specifies a data type. It may also specify a that further restricts the valid values of the domain and a that specifies the value to be used in the absence of an explicitly specified value or column default. A domain is described by a domain descriptor. A domain descriptor includes: - The name of the domain. - The data type descriptor of the data type of the domain. - The value of , if any, of the domain. - The domain constraint descriptors of the domain constraints, if any, of the domain. 4.17.3 Domain constraints A domain constraint is a constraint that is specified for a domain. It is applied to all columns that are based on that domain, and to all values cast to that domain. A domain constraint is described by a domain constraint descriptor. In addition to the components of every constraint descriptor a domain constraint descriptor includes: - The

. A domain constraint is satisfied by SQL-data if and only if, for any table T that has a column named C based on that domain, the specified , with each occurrence of VALUE replaced by C, is not False for any row of T. A domain constraint is satisfied by the result of a if and only if the specified , with each occurrence of VALUE replaced by that result, is not False.

The following features are supported:

• Constraint
• Default Value

Method Detail

getConstraint

public org.eclipse.emf.common.util.EList getConstraint()

Returns the value of the 'Constraint' containment reference list. The list contents are of type CheckConstraint.

If the meaning of the 'Constraint' containment reference list isn't clear, there really should be more of a description here...

Returns:

the value of the 'Constraint' containment reference list.

SQLDataTypesPackage.getDomain_Constraint()

getDefaultValue

public java.lang.String getDefaultValue()

Returns the value of the 'Default Value' attribute.

If the meaning of the 'Default Value' attribute isn't clear, there really should be more of a description here...

Returns:

the value of the 'Default Value' attribute.

See Also:

setDefaultValue(String), SQLDataTypesPackage.getDomain_DefaultValue()

setDefaultValue

public void setDefaultValue(java.lang.String value)

Sets the value of the 'Default Value' attribute.

Parameters:

value - the new value of the 'Default Value' attribute.
