Methods

Modifier and Type	Method and Description
protected List	checkForAddedForeignKeys(Database sourceModel, Database intermediateModel, Database targetModel) Creates change objects for foreign keys that are not present in the given source model but are in the target model, and applies them to the given intermediate model.
protected List	checkForAddedIndexes(Database sourceModel, Table sourceTable, Database intermediateModel, Table intermediateTable, Database targetModel, Table targetTable) Creates change objects for indexes that are not present in the given source table but are in the target table, and applies them to the given intermediate model.
protected List	checkForPrimaryKeyChanges(Database sourceModel, Table sourceTable, Database intermediateModel, Table intermediateTable, Database targetModel, Table targetTable) Creates change objects for primary key differences (primary key added/removed/changed), and applies them to the given intermediate model.
protected List	checkForRemovedForeignKeys(Database sourceModel, Database intermediateModel, Database targetModel) Creates change objects for foreign keys that are present in the given source model but are no longer in the target model, and applies them to the given intermediate model.
protected List	checkForRemovedIndexes(Database sourceModel, Table sourceTable, Database intermediateModel, Table intermediateTable, Database targetModel, Table targetTable) Creates change objects for indexes that are present in the given source table but are no longer in the target table, and applies them to the given intermediate model.

Constructor Detail

MSSqlModelComparator

public MSSqlModelComparator(PlatformInfo platformInfo,
                    TableDefinitionChangesPredicate tableDefChangePredicate,
                    boolean caseSensitive)

Creates a new Sql Server model comparator object.

Parameters:

platformInfo - The platform info

tableDefChangePredicate - The predicate that defines whether tables changes are supported by the platform or not; all changes are supported if this is null

caseSensitive - Whether comparison is case sensitive

Method Detail

checkForPrimaryKeyChanges

protected List checkForPrimaryKeyChanges(Database sourceModel,
                             Table sourceTable,
                             Database intermediateModel,
                             Table intermediateTable,
                             Database targetModel,
                             Table targetTable)

Creates change objects for primary key differences (primary key added/removed/changed), and applies them to the given intermediate model.

Overrides:
