File Parameters<br />

Labels If the field names (column headers) are stored in the first line of the table, this control<br />

should be set to Embedded. The DIF format also allows field names to be<br />

explicitly specified, and if that is the case, this control should be set to Explicit. If<br />

the table contains no field names, the None alternative should be used.<br />

Clauses<br />

Where... Opens the Where Clause (page 212) dialog, with which is possible to create a<br />

where clause for the load statement.<br />

Clear Revokes the transformation and/or the where clause of a cross table.<br />

Prefixes<br />

Crosstable Opens the Crosstable (page 229) dialog where it is possible to set the parameters<br />

for a transformation of a cross table into a three- (or more) column table.<br />

Hierarchy... Opens the Hierarchy Parameters (page 214) dialog, where it is possible to set the<br />

parameters for a hierarchy table (parameters as they appear in the script in parentheses).<br />

Clear Revokes the transformation of a cross table or a hierarchy table.<br />

Note that if both a cross table transformation and a where clause are used, the where clause is evaluated<br />

first. It is thus not possible to first transform from a cross table and then apply a where clause. However, if<br />

there is a need to apply a where clause on an already transformed table, a construction with a temporary<br />

table will solve the problem:<br />

TempTable: Crosstable (…) Load … from …;<br />

RealTable: Load … resident TempTable where …;<br />

Drop Table TempTable;<br />

Specify Row Condition<br />
