在执行以下代码时，在雪花存储过程中的 Statement.execute 中无法识别数值“+i+”？

Question

Below is the stored procedure which uses for loop using java script

 create or replace procedure test()
    returns varchar
    language javascript
    execute as caller
    as
    $$
    for (var i = 1; i<= 10; i++)
    {
        var command8=` update table a set a.c1='some' from table b where a.source='gg' and b.c2=a.c2 and b.c3=a.c3 and (datediff(year,date(a.etl_create),current_date())= '"+i+"')`
        var stmt8=snowflake.createStatement({sqlText: command8});
        var rs8=stmt8.execute();
    }

Answer 1

To substitute a variable into a template literal, use ${variable} .

var command8=` update table a set a.c1='some' from table b where a.source='gg' and b.c2=a.c2 and b.c3=a.c3 and (datediff(year,date(a.etl_create),current_date())= '${i}')`

Answer 2

Using bidning variables :

for (var i = 1; i<= 10; i++)
{
    var command8=` update table a set a.c1='some' 
                   from table b 
                   where a.source='gg' and b.c2=a.c2 and b.c3=a.c3 
                    and (datediff(year,date(a.etl_create),current_date())= :1)`
    var stmt8=snowflake.createStatement({sqlText: command8, binds:[i]});
    var rs8=stmt8.execute();
}
