Method Detail

getSQL

java.lang.String getSQL()

The SQL query string to be performed.

Returns:

The SQL statement string.

getQuerySpaces

java.util.Set getQuerySpaces()

Any query spaces to apply to the query execution. Query spaces are used in Hibernate's auto-flushing mechanism to determine which entities need to be checked for pending changes.

Returns:

The query spaces

getNamedParameterBindPoints

java.util.Map getNamedParameterBindPoints()

A map representing positions within the supplied query to which we need to bind named parameters.

Optional, may return null if no named parameters.

The structure of the returned map (if one) as follows:

1. The keys into the map are the named parameter names
2. The corresponding value is either an Integer if the parameter occurs only once in the query; or a List of Integers if the parameter occurs more than once

getCustomQueryReturns

java.util.List getCustomQueryReturns()

A collection of descriptors describing the JDBC result set to be expected and how to map this result set.

Returns:

List of return descriptors.
