请问这个报错是什么意思？Not allowed to use dynamic function in sql statement
报错的语句是：select dynamicFunc(...) from t context by day
此处 dynamic function 指的是我用参数传进来的 func，也就是 sql 在函数里面执行，函数有一个 func 作为参数，在里面运行这个 func。
sym = `C`MS`MS`MS`IBM`IBM`C`C`C$SYMBOL
price= 49.6 29.46 29.52 30.02 174.97 175.23 50.76 50.32 51.29
qty = 2200 1900 2100 3200 6800 5400 1300 2500 8800
timestamp = [09:34:07,09:36:42,09:36:51,09:36:59,09:32:47,09:35:26,09:34:16,09:34:26,09:38:12]
t1 = table(timestamp, sym, qty, price)
//select *, cumsum(qty) from t1 context by sym
//select *, cumsum2(qty) from t1 context by sym
def demo(t, dynamicFunc) {
return select select *, dynamicFunc(qty) from t context by sym
}
demo(t1, cumsum)
