Chapter 3: <strong>Teradata</strong> T<strong>Pump</strong> Commands<br />

FILLER<br />

FILLER<br />

Purpose<br />

The FILLER command describes a named or unnamed field as filler which is not to be sent to<br />

<strong>Teradata</strong> <strong>Data</strong>base. Only fields relevant to this <strong>Teradata</strong> T<strong>Pump</strong> task need to be specified.<br />

Description<br />

Name of an input record field to which a nullexpr of a FIELD command refers;<br />

or to which a “condition” expression of the IMPORT command’s APPLY<br />

clause refers<br />

The only reason for naming a filler field is to enable one of these expressions to<br />

refer to it. A fieldname must obey the same rules for its construction as<br />

<strong>Teradata</strong> SQL column names.<br />

The reason for describing a field that is not to be sent to <strong>Teradata</strong> <strong>Data</strong>base<br />

and is not used in any of the expressions mentioned in the previous paragraph<br />

is to make it possible to specify startpos as an asterisk for subsequent fields of<br />

the input records. If the use of the asterisk is not important, fields that do not<br />

participate in the <strong>Teradata</strong> T<strong>Pump</strong> do not need to be defined.<br />

Starting position of a field of the data records in an external data source<br />

It may be specified as an unsigned decimal integer, which is a character<br />

position starting with 1, or as an asterisk, which is the next available character<br />

position beyond the preceding field.<br />

Note that where input records may be continued by use of the CONTINUEIF<br />

condition, a startpos specified as an unsigned integer refers to a character<br />

position in the final concatenated result from which the continuation<br />

indicators have been removed. Refer to the description of the condition<br />

parameter of the LAYOUT command.<br />

Type and length of data in the field<br />
