Interface NativeSqlStrategy

All Superinterfaces:
org.springframework.core.Ordered
All Known Implementing Classes:
DefaultApplicationOwnedCatalogNativeSqlStrategy, DefaultMultiRootCatalogGraphNativeSqlStrategy, DefaultMultiTopDownCatalogGraphNativeSqlStrategy, HsqlApplicationOwnedCatalogNativeSqlStrategy, HsqlMultiRootCatalogGraphNativeSqlStrategy, HsqlMultiTopDownCatalogGraphNativeSqlStrategy, OracleApplicationOwnedCatalogNativeSqlStrategy, OracleMultiRootCatalogGraphNativeSqlStrategy, OracleMultiTopDownCatalogGraphNativeSqlStrategy
public interface NativeSqlStrategy extends org.springframework.core.Ordered
In some cases, native SQL is required to perform specialized database operations. For example, we use this in order to walk relationship graphs using CTE recursive queries written in platform specific syntax. This structure allows registration in Spring of a strategy for query generation specific to database platform.

Note, the general pattern for override of an existing strategy is to declare a new valid strategy of the same name with a lesser order. That strategy with the lesser order will be picked up first and used instead.
