Loading data into Sybase IQ from a Remote Server

     

Sybase IQ : Loading a table from a remote server

Please note: Until recently, the only way to load a table in Sybase IQ was to have the data file(s) reside on the same host machine as the database process. Now, superior load performance can be attained from a remote machine (a separate host machine on your network).

In ASE and Oracle, most developers are used to using BCP or SQL-Loader.

For Sybase IQ, the optimal way to load a table from a remote server is via the dbisql utility, and the "load table" command.

Load Table : Where the file does not reside on the database server
  • a bit slower than normal "load table"
  • requires use of JDBC connection, or DBISQL (no TDS)
  • need this setting: set option public.allow_read_client_file = 'on'
  • need this grant: grant READCLIENTFILE to dbuser
  • need this clause in LOAD statement: using client file


Sample snippet to add to load table SQL:
 using client file
    '/home/jsmith/ccr2.dat'
 

Below is a conventional load table statement.
 
 LOAD TABLE MYDB.v_invoice (
  invoice_id ,
  invoice_key,
  invoice_cd ,
  status_cd ,
  restricted_ind ,
  country_id ,
  cust_id
 )
 from '/app/sybase/data/invoice/data/vc.dat'
 quotes off
 escapes off
 delimited by '|'
 row delimited by '\x0a'
 notify 1000
 on file error continue
 with checkpoint on
 go
 
 commit
 go
