    • drop

      public void drop(Statement st) throws SQLException
      Description copied from class: SQLComplexTable
      Drops the current table. NOTE: If explicitly created index tables exist they should be removed first or this method override.
      Overrides:

      Parameters:
      st - the query statement
      Throws:
      SQLException - if there is a problem with the execute update command

    • insert

      public long insert(Object... arguments) throws SQLException
      Description copied from class: SQLComplexTable
      Inserts a row(s) into the db. The arguments passed to this function are by definition not known, so they are left as a variable-length list of Object instances, to be interpreted by the implementer.
      Specified by:
      insert in class SQLComplexTable
      Parameters:
      arguments - any arguments required for the insert
      Returns:
      to be defined by the implementor
      Throws:
      SQLException - if there is a problem executing the insert command

      public Map<Long,VectorStoreEntry> readVectors() throws SQLException
      Read all vectors from table and generate an ID-based vector map
      Returns:
      vector map (ID->VectorStoreEntry)
      Throws:
      SQLException - if error occurs

    • queryVectorById

      public VectorResult queryVectorById(long id) throws SQLException
      Get vector details which correspond to specified vector ID
      Parameters:
      id - vector ID
      Returns:
      vector details
      Throws:
