Column

public Column(Class<? extends Relation> relationType,
              String catalogName,
              String schemaName,
              String tableName,

Method Detail

isForIndex

public boolean isForIndex()

setForIndex

public void setForIndex(boolean forIndex)

getRelation

public Relation getRelation()

getContainingObjects

public DatabaseObject[] getContainingObjects()

setRelation

public Column setRelation(Relation relation)

getSchema

public Schema getSchema()

getName

public String getName()

setName

public Column setName(String name)

Description copied from interface: DatabaseObject

Sets the name for the database object.

Parameters:

name - the new name for the database object

Returns:

a reference to the same object (implementing classes are expected to return a reference to the same object).

setName

public Column setName(String name,
                      boolean computed)

getComputed

public Boolean getComputed()

setComputed

public Column setComputed(Boolean computed)

isNullable

public Boolean isNullable()

setNullable

public Column setNullable(Boolean nullable)

getType

public DataType getType()

setType

public Column setType(DataType type)

getDefaultValue

public Object getDefaultValue()

setDefaultValue

public Column setDefaultValue(Object defaultValue)

getDefaultValueConstraintName

public String getDefaultValueConstraintName()

setDefaultValueConstraintName

public Column setDefaultValueConstraintName(String defaultValueConstraintName)

isAutoIncrement

public boolean isAutoIncrement()

getAutoIncrementInformation

public Column.AutoIncrementInformation getAutoIncrementInformation()

setAutoIncrementInformation

public void setAutoIncrementInformation(Column.AutoIncrementInformation autoIncrementInformation)

getDescending

public Boolean getDescending()

setDescending

public Column setDescending(Boolean descending)

getValidate

public boolean getValidate()

VALIDATE keyword defines whether a all constraints on a column in a table should be checked if it refers to a valid row or not.

Returns:

true if ENABLE VALIDATE (this is the default), or false if ENABLE NOVALIDATE.

setValidateNullable

public Column setValidateNullable(Boolean validateNullable)

Parameters:

validateNullable - - if validateNullable is set to FALSE then the constraint will be created with the 'ENABLE NOVALIDATE' mode. This means the constraint would be created, but that no check will be done to ensure old data has valid not null constraint - only new data would be checked to see if it complies with the constraint logic. The default state for not null constraint is to have 'ENABLE VALIDATE' set.

getValidateNullable

public boolean getValidateNullable()

Returns false for Nor null constraints created with ENABLE NOVALIDATE mode, otherwise returns true.

Returns:

true if validation is required for nullable constraints, false otherwise
