Field Detail

NONE

public static final FunctionalDependencyAnalysisSupportImpl NONE

No support for functional dependency analysis

TABLE_REFERENCE

public static final FunctionalDependencyAnalysisSupportImpl TABLE_REFERENCE

Only supports the analysis for a single table reference, i.e. no support for joins / unions

TABLE_GROUP

public static final FunctionalDependencyAnalysisSupportImpl TABLE_GROUP

Supports the analysis for single tables, a group of joined tables or a result set (e.g. union) as long as only table columns are selected, i.e. no constants (see TABLE_GROUP_AND_CONSTANTS)

TABLE_GROUP_AND_CONSTANTS

public static final FunctionalDependencyAnalysisSupportImpl TABLE_GROUP_AND_CONSTANTS

Fully supports the analysis for joined / union table groups, including any constant value (e.g. the literal clazz_ column used as table per class inheritance discriminator column)
