xp_read_file system procedure

Reads a file and returns the contents of the file as a LONG BINARY variable.

Syntax
xp_read_file( filename )
Arguments
  • filename   Use this LONG VARCHAR parameter to specify the name of the file for which to return the contents.

Remarks

The function reads the contents of the named file, and returns the result as a LONG BINARY value.

The filename is relative to the starting directory of the database server.

The function can be useful for inserting entire documents or images stored in files into tables. If the file cannot be read, the function returns NULL.

If the data file is in a different character set, you can use the CSCONVERT function to convert it. See CSCONVERT function [String].

You can also use the CSCONVERT function to address character set conversion requirements you have when using the xp_read_file system procedure. See CSCONVERT function [String].
