Replace

The replace prefix is used to drop the entire Qlik Sense table and replace it with a new table that is loaded or selected.

Syntax:  

Replace [only](loadstatement |selectstatement |map...usingstatement)

 

The replace prefix can be added to any LOAD, SELECT or map...using statement in the script. The replace LOAD/replace SELECT statement has the effect of dropping the entire Qlik Sense table, for which a table name is generated by the replace LOAD/replace SELECT statement, and replacing it with a new table containing the result of the replace LOAD/replace SELECT statement. The effect is the same during partial reload and full reload. The replace map...using statement causes mapping to take place also during partial script execution.

Arguments:  

Examples and results:

Example	Result
Tab1: Replace LOAD * from File1.csv;	During both normal and partial reload, the Qlik Sense table Tab1 is initially dropped. Thereafter new data is loaded from File1.csv and stored in Tab1.
Tab1: Replace only LOAD * from File1.csv;	During normal reload, this statement is disregarded. During partial reload, any Qlik Sense table previously named Tab1 is initially dropped. Thereafter new data is loaded from File1.csv and stored in Tab1.
Tab1: LOAD a,b,c from File1.csv; Replace LOAD a,b,c from File2.csv;	During normal reload, the file File1.csv is first read into the Qlik Sense table Tab1, but then immediately dropped and replaced by new data loaded from File2.csv. All data from File1.csv is lost. During partial reload, the entire Qlik Sense table Tab1 is initially dropped. Thereafter it is replaced by new data loaded from File2.csv.
Tab1: LOAD a,b,c from File1.csv; Replace only LOAD a,b,c from File2.csv;	During normal reload, data is loaded from File1.csv and stored in the Qlik Sense table Tab1. File2.csv is disregarded. During partial reload, the entire Qlik Sense table Tab1 is initially dropped. Thereafter it is replaced by new data loaded from File2.csv. All data from File1.csv is lost.
