Hi,

You can try to transpose the crosstab table first and then only use the concatenate function.

Difficult to understand without knowing your data or script.

need to either use concatenate or join function if necessary but accurate answer can be given only after knowing your data.

Thanks for the reply!

Here is my script:

Fault:
CrossTable(F1, Data1,3)
LOAD CLUSTERNO as F_Cluster1,
INSTANCE as F_INSTANCE1,
"EE_FLIGHTCNT" AS F_FlightCnt,
    ALT ,
    MN ,
    IAS;
SQL SELECT *
FROM "DPHM_V1".FAULT;

Concatenate(Fault)
CrossTable(F2, Data2,3)
LOAD CLUSTERNO as F_Cluster2,
INSTANCE as F_INSTANCE2,
    N1IN,
    N2IN ,
    P3IN;
    SQL SELECT *
FROM "DPHM_V1".FAULT;

I am getting error - Illegal combination of prefixes.

Hi Kumar Raman,

Thanks for your help. Its working fine.

But what would be the changes in script if i have more than 2 tables for concatenate.

Fault:
CrossTable(F1, Data1,3)
LOAD CLUSTERNO as F_Cluster1,
INSTANCE as F_INSTANCE1,
"EE_FLIGHTCNT" AS F_FlightCnt,
ALT ,
MN ,
IAS;
SQL SELECT *
FROM "DPHM_V1".FAULT;

Concatenate(Fault)
Fault2:
CrossTable(F2, Data2,3)
LOAD CLUSTERNO as F_Cluster2,
INSTANCE as F_INSTANCE2,

N1IN,
    N2IN ,
    P3IN;
    SQL SELECT *
FROM "DPHM_V1".FAULT;

Fault3:
CrossTable(F3, Data3,3)
LOAD CLUSTERNO as F_Cluster3,
INSTANCE as F_INSTANCE3,
ENGVIB ,
MOTIN ,
MOPIN ;
SQL SELECT *
FROM "DPHM_V1".FAULT;

My actual script is having more than 2 tables.

How about CrossTable 'ing all your tables individually first with no concatenates,

Then concatenating the resultant tables from resident into your target table name.

Then dropping the temporary CrossTable 'd tables.

Hi Neha,

Has Bill said its better to take resident and concatenate to your target table and drop them.

may be like the below script..

Fault:

CrossTable(F1, Data1,3)
LOAD CLUSTERNO as F_Cluster1,
INSTANCE as F_INSTANCE1,
"EE_FLIGHTCNT" AS F_FlightCnt,
ALT ,
MN ,
IAS;
SQL SELECT *
FROM "DPHM_V1".FAULT;

Temp_Fault:
CrossTable(F2, Data2,3)
LOAD CLUSTERNO as F_Cluster2,
INSTANCE as F_INSTANCE2,
N1IN,
N2IN ,
P3IN;
SQL SELECT *
FROM "DPHM_V1".FAULT;

NoConcatenate
Fault1:
Concatenate(Fault)
load *
Resident Temp_Fault;

drop table Temp_Fault;

Temp_Fault3:
CrossTable(F3, Data3,3)
LOAD CLUSTERNO as F_Cluster3,
INSTANCE as F_INSTANCE3,
ENGVIB ,
MOTIN ,
MOPIN ;
SQL SELECT *
FROM "DPHM_V1".FAULT;

NoConcatenate
Fault3:
Concatenate(Fault)
load *
Resident Temp_Fault3;

drop table Temp_Fault3;

First of all, we can't join or concatenate the two or more cross tables in qlikview. Its illegal syntax.

So first you need to create the TEMP tables with Cross Table after that concatenate all the temp tables by using resident tables. If the temp tables have more no of rows then create TEMP qvd's and then concatenate all the TEMP qvd's.
