Informix Adds Escape Signs (Backslash) During Unload Of Data As Part Of Migration To Oracle (Doc ID 1364275.1)

Last updated on NOVEMBER 28, 2016

Applies to:

Oracle Server - Enterprise Edition - Version: 8.1.7.0 to 11.2.0.3 - Release: 8.1.7 to 11.2
Information in this document applies to any platform.

Goal

Migration of Informix to Oracle through unload/upload of data.

During the unload at Informix certain characters in data are escaped (backslash + newline), implying that the data is being converted. These extra backslashes needs to be stripped/removed before/during loading the data into Oracle by SQL*Loader.

This behavior is described in the following presentation:

http://www.freewebs.com/willswins/Database/Informix/Migrating%20From%20Oracle%20to%20Informix%20-%20A%20Guide.pdf

=> page 9: BYTE and TEXT Data:
For example, when text data is unloaded from the INFORMIX 5.X
database, the newline characters which are part of the data are escaped by
the backslash (‘\’) character. If backslash (‘\’) is part of the data, it is also
escaped by ‘\’.
