Error description

  • CREATE CLUSTER INDEX physically rebuilds the table and all
    indices which already exist on a table. This may take a long
    time for large tables. For performance reasons these statements
    should be written before all other CREATE INDEX statements
    
    For Example:
    
    Current dbschema output:
    
    create table "informix".mytab
    (
      id integer,
      a1 char(5),
      b1 integer
    );
    
    revoke all on "informix".mytab from "public" as "informix";
    
    create index "informix".aidx on "informix".mytab (a1) using
    btree;
    create index "informix".bidx on "informix".mytab (b1) using
    btree;
    create cluster index "informix".cidx on "informix".mytab (id)
    usingbtree ;
    
    Required dbschema output:
                         {
    create table "informix".mytab
    (
      id integer,
      a1 char(5),
      b1 integer
    );
    
    revoke all on "informix".mytab from "public" as "informix";
    
    create cluster index "informix".cidx on "informix".mytab (id)
    usingbtree ;
    create index "informix".aidx on "informix".mytab (a1) using
    btree;
    create index "informix".bidx on "informix".mytab (b1) using
    btree;
