For the given list of columns, disable "nullable" for those columns that are primary key columns.

Parameters
columns:ArrayList<Column>

the list of columns

createConstraintsback to summary
protected void createConstraints()

Create the constraints.

generateSequencesback to summary
protected ArrayList<Sequence> generateSequences(ArrayList<Column> columns, boolean temporary)

For the given list of columns, create sequences for identity columns (if needed), and then get the list of all sequences of the columns.

Parameters
columns:ArrayList<Column>

the columns

temporary:boolean

whether generated sequences should be temporary

Returns:ArrayList<Sequence>

the list of sequences (may be empty)

public AlterTableAddConstraint getPrimaryKey()
setPrimaryKeyback to summary
private boolean setPrimaryKey(AlterTableAddConstraint primaryKey)

Set the primary key, but also check if a primary key with different columns is already defined.

If an unnamed primary key with the same columns is already defined it is removed from the list of constraints and this method returns false.

Parameters
primaryKey:AlterTableAddConstraint

the primary key

Returns:boolean

whether another primary key with the same columns was already set and the specified primary key should be ignored
