  • Method Details

    • getStaticPartitions

      public org.apache.calcite.sql.SqlNodeList getStaticPartitions()
      Returns:
      the list of partition key-value pairs, returns empty if there is no partition specifications.

    • getStaticPartitionKVs

      public LinkedHashMap<String,String> getStaticPartitionKVs()
      Get static partition key value pair as strings.

      For character literals we return the unquoted and unescaped values. For other types we use SqlNode.toString() to get the string format of the value literal. If the string format is not what you need, use getStaticPartitions().

      Returns:
      the mapping of column names to values of partition specifications, returns an empty map if there is no partition specifications.

    • getTargetTableID

      public org.apache.calcite.sql.SqlNode getTargetTableID()
      Returns the target table identifier.

    • getTableHints

      public org.apache.calcite.sql.SqlNodeList getTableHints()
      Returns the table hints as list of SqlNode for current insert node.

    • unparse

      public void unparse(org.apache.calcite.sql.SqlWriter writer, int leftPrec, int rightPrec)
      Overrides:
      unparse in class org.apache.calcite.sql.SqlInsert

    • isUpsert

      public static boolean isUpsert(List<org.apache.calcite.sql.SqlLiteral> keywords)

    • isOverwrite

      public boolean isOverwrite()
      Returns whether the insert mode is overwrite (for whole table or for specific partitions).
      Returns:
      true if this is overwrite mode
