Method Details

createJdbcParameterBindings

public JdbcParameterBindings createJdbcParameterBindings(DomainQueryExecutionContext context)

Description copied from interface: MultiTableHandler

Create the JdbcParameterBindings for this multi-table handler based on the execution context.

Specified by:

createJdbcParameterBindings in interface MultiTableHandler

Parameters:

context - Contextual information needed for execution

Returns:

The built parameter bindings

dependsOnParameterBindings

public boolean dependsOnParameterBindings()

Description copied from interface: MultiTableHandler

Signals that the SQL depends on the parameter bindings e.g. due to the need for inlining of parameter values or multiValued parameters.

Specified by:

dependsOnParameterBindings in interface Handler

Specified by:

dependsOnParameterBindings in interface MultiTableHandler

isCompatibleWith

public boolean isCompatibleWith(JdbcParameterBindings jdbcParameterBindings,
 QueryOptions queryOptions)

Specified by:

isCompatibleWith in interface Handler

Specified by:

isCompatibleWith in interface MultiTableHandler

execute

public int execute(JdbcParameterBindings jdbcParameterBindings,
 DomainQueryExecutionContext context)

Description copied from interface: MultiTableHandler

Execute the multi-table update or delete indicated by the SQM AST passed in when this Handler was created.

Specified by:

Parameters:

jdbcParameterBindings - The parameter bindings for JDBC parameters

context - Contextual information needed for execution

Returns:

The "number of rows affected" count
