Case insensitive query using Spring @Query annotation

Question

I have a Spring JPA repository where I have a custom query:

@Query("select aif from AssetInFolder aif "
        + "where (aif.asset.name like %:name% "
        + "or aif.folder.name like %:name% "
        + "or aif.asset.assetCode like :code%) "
        + "and aif.folder.assetVersion.id = :version")
public List<AssetInFolder> searchForAsset(@Param("name") String name, @Param("code") String code,  @Param("version") int version);

I would like to make sure that the the first part of the query (before the 'and') is case in sensitive. I have tried changing it to:

@Query("select aif from AssetInFolder aif "
            + "where (UPPER(aif.asset.name) like UPPER(%:name%) "
            + "or UPPER(aif.folder.name) like UPPER(%:name%) "
            + "or UPPER(aif.asset.assetCode) like UPPER(:code%)) "
            + "and aif.folder.assetVersion.id = :version")

But I get a NullPointer when Spring attempt to initialise the application context:

However, more curiously, if I write remove a few of the UPPER calls I can get it to start:

@Query("select aif from AssetInFolder aif "
            + "where (UPPER(aif.asset.name) like UPPER(%:name%) "
            + "or aif.folder.name like %:name% "
            + "or aif.asset.assetCode like :code%) "
            + "and aif.folder.assetVersion.id = :version")

Anyone got any ideas? I'm on Spring 4.2.2 and Spring Data JPA 1.9.0

Answer 1

I ended up only calling UPPER on the column names and relying on the caller to pass in the parameters in upper case. So my query ended up as:

@Query("select aif from AssetInFolder aif "
            + "where (UPPER(aif.asset.name) like %:name% "
            + "or UPPER(aif.folder.name) like %:name% "
            + "or UPPER(aif.asset.assetCode) like :code%) "
            + "and aif.folder.assetVersion.id = :version")

This fixed the issue, however I'm still unsure as to why the original query didn't work.
