Method Details

supportsRowLevelSecurity

public boolean supportsRowLevelSecurity()

Description copied from interface: RowLevelSecurity

Does this dialect natively support row-level security?

Specified by:

supportsRowLevelSecurity in interface RowLevelSecurity

addTenantIdTableInitCommands

public void addTenantIdTableInitCommands(InFlightMetadataCollector collector,
 Table table,
 Column tenantIdentifierColumn,
 Metadata metadata,
 RowLevelSecurity.TenantIdentifierSource tenantIdentifierSource)

Description copied from interface: RowLevelSecurity

Register table initialization commands enforcing discriminator-based multitenancy via native row-level security.

Specified by:

addTenantIdTableInitCommands in interface RowLevelSecurity

Parameters:

collector - The metadata collector

table - The table containing the tenant id column

tenantIdentifierColumn - The tenant id column

metadata - The mapping metadata

tenantIdentifierSource - The source used to resolve the tenant id

getTenantIdTableCreateStrings

public String[] getTenantIdTableCreateStrings(Table table,
 Column tenantIdentifierColumn,
 Metadata metadata,
 SqlStringGenerationContext context,
 RowLevelSecurity.TenantIdentifierSource tenantIdentifierSource)

Description copied from interface: RowLevelSecurity

Create the DDL commands which enforce discriminator-based multitenancy via native row-level security.

Specified by:

getTenantIdTableCreateStrings in interface RowLevelSecurity

Parameters:

table - The table containing the tenant id column

tenantIdentifierColumn - The tenant id column

metadata - The mapping metadata

context - SQL rendering context

tenantIdentifierSource - The source used to resolve the tenant id

setTenantIdentifier

public void setTenantIdentifier(Connection connection,
 String tenantIdentifier,
 boolean root)
                         throws SQLException

Description copied from interface: RowLevelSecurity

Apply the current Hibernate tenant identifier to the database connection. Dialects may use this to populate session-local state referenced by their row-level security policies.

Specified by:

setTenantIdentifier in interface RowLevelSecurity

Parameters:

connection - The JDBC connection

tenantIdentifier - The tenant identifier rendered as a string

root - Whether the tenant identifier is a root tenant
