  2. abstract def up(): Unit

    This value is true if the database implicitly adds an index on the column that has a foreign key constraint added to it.

    This value is true if the database implicitly adds an index on the column that has a foreign key constraint added to it.

    The following SQL can be used to test the database. The last statement will fail with a message that there already is an index on the column.

    create table parent (pk int primary key); create table child (pk int primary key, pk_parent int not null); alter table child add constraint idx_child_pk_parent foreign key (pk_parent) references parent (pk); create index idx_child_pk_parent on child (pk_parent);

    Alter the definition of an existing column.

    Alter the definition of an existing column.

    NOTE: if the original column definition uses CharacterSet() then it must be used here again, unless the base SQL data type is being changed. For example, on Oracle, creating a column without CharacterSet uses VARCHAR2 while using CharacterSet(Unicode) uses NVARCHAR2, so if the original column used CharacterSet(Unicode) and #alterColumn() is not passed CharacterSet(Unicode), then the column's data type will be change from NVARCHAR2 to VARCHAR2.

    the name of the table with the column

    column_name

    Get the raw connection to the database the migration can use for any custom work. This connection is the raw connection that underlies the logging connection and does not log any operations performed on it. It should only be used when the logging connection does not provide a required feature.

    Given a SQL string and a Function1[PreparedStatement,Unit], start a new transaction by turning off auto-commit mode on the connection then create a new prepared statement with the SQL string and pass the prepared statement to the closure argument.

    Given a SQL string and a Function1[PreparedStatement,Unit], start a new transaction by turning off auto-commit mode on the connection then create a new prepared statement with the SQL string and pass the prepared statement to the closure argument. The closure should not perform the commit as this method will commit the transaction.

Finally, the auto-commit state is reset to the value the connection had before this method was called.

    returns
