Description copied from class: QueryTreeNode

Initialize a query tree node.

Overrides:

init in class QueryTreeNode

---

toString

public java.lang.String toString()

Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.

Overrides:

toString in class TableElementNode

---

bind

protected void bind(DDLStatementNode ddlNode,
                    org.apache.derby.iapi.sql.dictionary.DataDictionary dd)
             throws org.apache.derby.iapi.error.StandardException

Bind this constraint definition.

---

getConstraintMoniker

java.lang.String getConstraintMoniker()

Get the name of the constraint. If the user didn't provide one, we make one up. This allows Replication to agree with the core compiler on the names of constraints.

---

getDropSchemaName

java.lang.String getDropSchemaName()

To support dropping exisiting constraints that may have mismatched schema names we need to support ALTER TABLE S1.T DROP CONSTRAINT S2.C. If a constraint name was specified this returns it, otherwise it returns null.

---

getBackingIndexUUID

org.apache.derby.catalog.UUID getBackingIndexUUID()

Allocates a UUID if one doesn't already exist for the index backing this constraint. This allows Replication logic to agree with the core compiler on what the UUIDs of indices are.

---

getBackingIndexName

java.lang.String getBackingIndexName(org.apache.derby.iapi.sql.dictionary.DataDictionary dd)

Gets a unique name for the backing index for this constraint of the form SQLyymmddhhmmssxxn yy - year, mm - month, dd - day of month, hh - hour, mm - minute, ss - second, xx - the first 2 digits of millisec because we don't have enough space to keep the exact millisec value, n - number between 0-9

---

setAuxiliaryProviderList

void setAuxiliaryProviderList(org.apache.derby.iapi.sql.depend.ProviderList apl)

Set the auxiliary provider list.

---

getAuxiliaryProviderList

boolean requiresUniqueIndex()

Is this a foreign key constraint.

---

setProperties

public void setProperties(java.util.Properties properties)

Set the optional properties for the backing index to this constraint.

public boolean isEnabled()

Is this constraint enabled.

---

getColumnList

public ResultColumnList getColumnList()

Get the column list from this node.

---

setColumnList

public void setColumnList(ResultColumnList columnList)

Set the column list for this node. This is useful for check constraints where the list of referenced columns is built at bind time.

Get the check condition from this table constraint.

---

setCheckCondition

public void setCheckCondition(ValueNode checkCondition)

Set the check condition for this table constraint.
