IMPORT
Syntax Element
'c'
Description
Optional specification of the delimiter characters that separate fields in the
variable-length text records of the input data source
The default, if a 'c' specification is not used, is the vertical bar character ( | ).
When the character set of the job script is different from the client character
set used for the job (for example, on z/OS the job script must be in Teradata
EBCDIC when using the UTF8 client character set, or UTF-16 client
character set can be used with the job script in UTF8), Teradata TPump will
translate the effective delimiter from the script character set form to the client
character set form before separating the fields with it.
For example, when the client character set is UTF-16 and the script character
set is UTF8, if the following command is given:
… FORMAT VARTEXT '-' ...
Teradata TPump translates '-' from the UTF8 form to the UTF-16 form and
then separate the fields in the record according to the UTF-16 form of '-'.
Similarly, on the mainframe, when the client character set is UTF8 and the
script character set is Teradata EBCDIC, if the following command is given:
… FORMAT VARTEXT '6A'xc ...
Teradata TPump interprets x'6A' according to Teradata EBCDIC and
translates it to the corresponding Unicode code point, U+007C "VERTICAL
LINE", and uses the UTF8 encoding scheme of U+007C, 0x7C (which is '|' in
7-bit ASCII), as the delimiter character for the record.
Caution: When using the UTF8 client set on the mainframe, examine the
definition in the International Character Set Support manual to
determine the code points of the special characters required.
Different versions of EBCDIC do not always agree as to the
placement of these characters.
For example, the code point of '|' in most IBM EBCDIC code pages
is x'4F'. If a '|' is specified as the delimiter in the script or the
delimiter to default in a system environment using such an IBM
EBCDIC code page is left, (which is essentially the same as
specifying '|'), but the UTF8 data uses x'7C' ('|' in Unicode) as the
delimiter, the job will run into errors because:
• the code point of x'4F' in Teradata EBCDIC maps to U+008D but not
U+007C, and
• the delimiter must use single-byte characters when it is in the client
character set form.
