setIsLog

public static void setIsLog(boolean isLog)

Set if the greendao will log the resulting SQL command and the passed values when calling one of the build methods. Like this you can compare if you actually get what you expected. It might also help to copy generated SQL into some SQLite database explorer and execute it with the values.

参数:

isLog -

getList

public static java.util.List getList(AbstractDao dao,
                     Property orderProperty,

                     WhereCondition... whereConditions)

Executes the query and returns the result as a list containing all entities loaded into memory.

参数:

public static java.util.List queryBuilderList(AbstractDao dao,
                              WhereCondition cond,
                              WhereCondition... condmore)

queryBuilderLazyList

public static LazyList queryBuilderLazyList(AbstractDao dao,
                            WhereCondition cond,
                            WhereCondition... condmore)

Executes the query and returns the result as a list that lazy loads the entities on first access. Entities are cached, so accessing the same entity more than once will not result in loading an entity from the underlying cursor again.Make sure to close it to close the underlying cursor.

参数:

dao -

cond -

condmore -

返回:

query

public static Query query(AbstractDao dao,
          java.lang.String queryString,
          java.lang.String queryValue)

Creates a repeatable Query object based on the given raw SQL where you can pass any WHERE clause and arguments.

参数:

dao -

queryString -

queryValue -

返回:

query

public static Query query(AbstractDao dao,
          java.lang.String queryString)

Creates a repeatable Query object based on the given raw SQL where you can pass any WHERE clause and arguments.

参数:

public static void insert(AbstractDao dao,
          java.lang.Object entity)

Insert an entity into the table associated with a concrete DAO.

参数:

dao -

entity -

insert

public static void insert(AbstractDao dao,
          java.util.List entities)

Insert an entity into the table associated with a concrete DAO.

                   java.util.List entities)

delete

public static void delete(AbstractDao dao,
          java.lang.Object entity)

Deletes the given entity from the database. Currently, only single value PK entities are supported.

参数:

dao -

entity -

delete

public static void delete(AbstractDao dao,
          java.util.List entities)

Deletes the given entities in the database using a transaction.

getQueryBuilder

public static QueryBuilder getQueryBuilder(AbstractDao dao,
                           WhereCondition cond,

public static void deleteByCondition(AbstractDao dao,
                     WhereCondition cond,
                     WhereCondition... condmore)

Deletes all matching entities without detaching them from the identity scope (aka session/cache). Note that this method may lead to stale entity objects in the session cache. Stale entities may be returned when loaded by their primary key, but not using queries.
