I'm trying to multiply accountid column with 10 while loading data from the external stage to the snowflake table.
Below is the query used in snowflake:
copy into account(accountid, accounttype)
from (select to_number(t.$1,10,1)*10, t.$4 from @azure_ext_stg/snowflake/account.csv t)
file_format = my_csv_format
FORCE = TRUE;

The query you provided is a Snowflake COPY command used to load data from an external stage (in this case, an Azure stage) into a Snowflake table. It appears that you want to multiply the values in the accountid column by 10 while loading the data. However, there is a small syntax issue in your query.


Here's the corrected version of the query:
copy into account(accountid, accounttype)
from (select to_number(t.$1, '99'), t.$4 * 10 from @azure_ext_stg/snowflake/account.csv t)
file_format = my_csv_format
FORCE = TRUE; angry gran
In the subquery, the to_number() function is used to convert the first column (t.$1) to a numeric value. The '99' parameter specifies the format of the number. Then, the second column (t.$4) is multiplied by 10 to achieve the desired multiplication. Please ensure that the column indexes ($1, $4) are correct based on your CSV file structure, and adjust them accordingly if needed. Also, make sure you have the appropriate file format (my_csv_format) defined in Snowflake to handle the CSV file properly.
