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.

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.

isCompatibleWith

public boolean isCompatibleWith(JdbcParameterBindings jdbcParameterBindings,
 QueryOptions queryOptions)

execute

public int execute(JdbcParameterBindings jdbcParameterBindings,
 DomainQueryExecutionContext executionContext)

Description copied from interface: MultiTableHandler

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

Parameters:

jdbcParameterBindings - The parameter bindings for JDBC parameters

executionContext - Contextual information needed for execution

Returns:

The "number of rows affected" count
