I want to connect two tables. The first one contains one row for each client and has the following:
ID Name
01 ABC
02 DEF
03 GHI
04 JKL
In the second table I have payments by payment date as follows:
Month ID Amount
Jan 01 500
Feb 01 123
Feb 02 256
Mar 04 589
Jan 04 563
In actual data I have 17 million records in the second table and it connects to around 5,000 records in the first table. While QV does the connection well it takes time and space to reload data.
Since the first table has only one row for each client is it possible to aggregate the information in the second table by ID. I do not need the Month for this purpose.
Would appreciate guidance in this matter.
Thanks & regards
yes it possible
C:
load * inline [
ID , Name
01 , ABC
02 , DEF
03 , GHI
04 , JKL
];
left join (C)
load ID, sum(Amount) as Amount group by ID;
load * inline [
Month , ID , Amount
Jan , 01 , 500
Feb , 01 , 123
Feb , 02 , 256
Mar , 04 , 589
Jan , 04 , 563
];
or if you prefere 2 tables
C:
load * inline [
ID , Name
01 , ABC
02 , DEF
03 , GHI
04 , JKL
];
P:
load ID, sum(Amount) as Amount group by ID;
load * inline [
Month , ID , Amount
Jan , 01 , 500
Feb , 01 , 123
Feb , 02 , 256
Mar , 04 , 589
Jan , 04 , 563
];

load
