i have an SQLite table with three columns as below



Table A
 BOM Date Consumption
 salt Mar 8, 2019 0.7 
 pepper Mar 8, 2019 0.1
 Rice Mar 8, 2019 0.8 
 salt Mar 8, 2019 0.5
 pepper Mar 8, 2019 0.2


I want to group the data in the BOM column such that it sums the values for each group in the consumption table to give me a result as below



Table B
 BOM Date Consumption
 salt Mar 8, 2019 (0.7+0.5) 
 pepper Mar 8, 2019 (0.1+0.2)
 Rice Mar 8, 2019 0.8


my code which is giving me a syntax error for which I am yet to resolve is as below



 UPDATE Table_B
 SET
 Table_B_BOM, Table_B_Date, Table_B_Consumption(
 SELECT sum(*)
 FROM Table_A 
 )
