1) Trying to get index and corresponding columns information of all the tables in mentioned schema

select inx.table_name as table_name, inx.index_name as index_name,column_name, case ( when inx.index_type = 'IOT - TOP' then 'Y' else 'N' end,
    case
     when inx.uniqueness = 'UNIQUE' then 'Y'
     when inx.uniqueness = 'NONUNIQUE' then 'N'
     end,
     'N' as ignore_dup_key,
     cast(inc.column_position as NUMBER(10))
     from    all_indexes         inx,
     all_ind_columns     inc
      where   inx.owner           = '" + database.toUpperCase() + "'
      and     inx.table_name      = inc.table_name
      and     inx.index_name      = inc.index_name
      and     inx.owner           = inc.index_owner
     and     inx.owner           = inc.table_owner
     and     inx.dropped         = 'NO'
     and     inx.table_name       = '" + tableName.toUpperCase() + "'
     order by inx.table_name, inx.index_name, cast(inc.column_position as NUMBER(10))

2) Trying to get the columns information of all the tables in mentioned schema

select   tab.TABLE_NAME,
                  col.COLUMN_NAME,
                  col.DATA_TYPE,
                  cast(case when col.CHAR_COL_DECL_LENGTH is NULL then col.DATA_PRECISION else col.CHAR_LENGTH end as NUMBER(10)),
                  cast(col.NULLABLE as CHAR(1)),
                  cast(col.COLUMN_ID as NUMBER(10))

         from    all_tab_columns    col,
                 all_tables         tab
         where   tab.TABLE_NAME        = col.TABLE_NAME
         and     tab.OWNER             = col.OWNER
         and     tab.OWNER             = '" + database.toUpperCase() + "'
         and     tab.DROPPED           = 'NO'
        and     tab.TABLE_NAME       = '" + tableName.toUpperCase() + "'
        order by tab.TABLE_NAME, cast(col.COLUMN_ID as NUMBER(10))
