Drop Table
One or several QlikView internal tables can be dropped from memory at any time during script execution,
by means of a drop table statement. The following items will be lost as a result of this:
l The actual table(s).
l All fields which are not part of remaining tables.
l Field values in remaining fields, which came exclusively from the dropped table(s).
The syntax is:
drop table[ s ]tablename [, tablename2 ...]
The forms drop table and drop tables are both accepted.
Examples:
drop table Orders, Salesmen, T456a;
This line results in three tables being dropped from memory.
Tab1:
select * from Trans;
load Customer, Sum( sales ) resident Tab1 group by Month;
drop table Tab1;
As a result only the aggregates remain in the memory. Trans data is discarded.

Execute
With the execute statement it is possible to run other programs during the re-execution of the QlikView
script, e.g. conversions that are necessary.
The syntax is:
execute commandline
where:
commandline is a text that can be interpreted by the operating system as a command line.
Examples:
Execute C:\Program Files\Office12\Excel.exe;
Execute winword macro.doc;
Execute cmd.exe /C C:\BatFiles\Log.bat
Note!
The /C needs to be included as it is a parameter to cmd.exe.
