(1) Re-creating a plug-in index
- Example 1
- This example re-creates a plug-in index (INDEX1) defined for a table (TABLE1) with columns of abstract data type (SGMLTEXT). The abstract data type (SGMLTEXT) is provided by the HiRDB Text Search Plug-in.
- The example assumes that the following table and index have been defined:
CREATE TABLE TABLE1(C1 INT,C2 SGMLTEXT
ALLOCATE (SGMLTEXT IN LOBUSER01)
PLUGIN'<DTD>sgml.dtd</DTD>' ) IN PDBUSER01
- Plug-in index definition:
CREATE INDEX INDEX1 USING TYPE NGRAM ON TABLE1(C2)
IN LOBUSER02

- Explanation of the command
- This example creates a plug-in index (INDEX1) defined for a table (TABLE1).
- -k ixrc: Specification for index re-creation
- -t TABLE1: Name of the table subject to index re-creation
- c:\hirdb\pdrorg\control_file: Name of the control information file
- Contents of the control information file (c:\hirdb\pdrorg\control_file)
index INDEX1 LOBUSER02 c:\hirdb\pdrorg\index_file 1
|
- Explanation:
- Specifies the index information file to which plug-in index information is to be output:
INDEX1: Identifier of the plug-in index to be created
LOBUSER02: Name of the RDAREA storing the plug-in index to be created
c:\hirdb\pdrorg\index_file: Name of the index information file to which index information is output
(2) Re-creating an index in units of index storage RDAREAs
- Example 2
- This example re-creates an index (INDEX1) in units of RDAREAs (PDBUSER03).
- The example assumes that the following table and indexes have been defined:
CREATE TABLE TABLE1(C1 INT NOT NULL,C2 CHAR(8),C3 INT)
IN ((PDBUSER01) C1 > 10,(PDBUSER02))
- Index definition (partitioning key index):
CREATE INDEX INDEX1 ON TABLE1(C1)
IN ((PDBUSER03),(PDBUSER05))
- Index definition (non-partitioning key index):
CREATE INDEX INDEX2 ON TABLE1(C2,C1)
IN ((PDBUSER04),(PDBUSER06))

- Explanation of the command
- This example re-creates indexes (INDEX1 and INDEX2).
- -k ixrc: Specification for index re-creation
- -t TABLE1: Name of the table subject to index re-creation
- c:\hirdb\pdrorg\control_file: Name of the control information file
- Contents of the control information file (c:\hirdb\pdrorg\control_file)
index INDEX1 PDBUSER03 c:\hirdb\pdrorg\index_inf1 1
sort bes1 c:\hirdb\pdrorg\sortwork,8192 2
|
- Explanation:
- Specifies the index information file:
INDEX1: Index identifier
PDBUSER03: Name of the index storage RDAREA
c:\hirdb\pdrorg\index_inf1: Name of the index information file
- Specifies the work directory for sorting:
bes1: Name of the server used to create the sort work file
c:\hirdb\pdrorg\sortwork: Name of the directory in which the sort work file is created
8192: Size of buffer for sorting (in KB)
(3) Re-creating indexes in units of indexes
- Example 3
- This example re-creates indexes (INDEX1 and INDEX2) defined for a row-partitioned table (TABLE1).
- The example assumes that the following table and indexes have been defined:
CREATE TABLE TABLE1(C1 INT,C2 INT NOT NULL)
IN ((PDBUSER01) C2<200,(PDBUSER02) C2<400,(PDBUSER03))
CREATE INDEX INDEX1 ON TABLE1(C2) IN ((IDX01),(IDX02),(IDX03))
CREATE INDEX INDEX2 ON TABLE1(C1) IN ((IDX04),(IDX05))
