| ModifyColumnNode | | public class ModifyColumnNode extends ColumnDefinitionNode (Code) | | A ModifyColumnNode represents a modify column in an ALTER TABLE statement.

| columnPosition | | int columnPosition(Code) | | |
| checkExistingConstraints | | public void checkExistingConstraints(TableDescriptor td) throws StandardException(Code) | | If the type of a column is being changed (for mulan, the length of the
column is being increased then make sure that this does not violate
any key constraints;
the column being altered is
1. part of foreign key constraint
==> ERROR. This references a Primary Key constraint and the
type & lengths of the pkey/fkey must match exactly.
2. part of a unique/primary key constraint
==> OK if no fkey references this constraint.
==> ERROR if any fkey in the system references this constraint.
Parameters:
td - The Table Descriptor on which the ALTER is being done.
exception:
StandardException - Thrown on Error. |
| checkUserType | | public void checkUserType(TableDescriptor td) throws StandardException(Code) | | Check the validity of a user type. Checks that
1. the column type is either varchar, ....
2. is the same type after the alter.
3. length is greater than the old length.
exception:
StandardException - Thrown on error |
| getAction | | int getAction()(Code) | | Get the action associated with this node.
The action associated with this node. |
| getColumnPosition | | public int getColumnPosition()(Code) | | Get the column position for the column.
The column position for the column. |
| getOldDefaultUUID | | UUID getOldDefaultUUID()(Code) | | Get the UUID of the old column default.
The UUID of the old column default. |
| validateAutoincrement | | public void validateAutoincrement(DataDictionary dd, TableDescriptor td, int tableType) throws StandardException(Code) | | check the validity of autoincrement values in the case that we are
modifying an existing column (includes checking if autoincrement is set
when making a column nullable)
