用法
>>> import ibis
>>> t = ibis.table(
[("a", "string"), ("b", "float"), ("c", "int32"), ("d", "int64"), ("e", "int64")],
"t",
)
>>> expr = t.group_by(["a", "b"]).aggregate([t.c.sum().name("sum")]).select("b", "sum")
>>> expr
r0 := UnboundTable: t
a string
b float64
c int32
d int64
e int64
r1 := Aggregation[r0]
metrics:
sum: Sum(r0.c)
by:
a: r0.a
b: r0.b
Selection[r1]
selections:
b: r1.b
sum: r1.sum
>>> ibis.show_sql(expr)
SELECT
t0.b,
t0.sum
FROM (
SELECT
t1.a AS a,
t1.b AS b,
SUM(t1.c) AS sum
FROM t AS t1
GROUP BY
t1.a,
t1.b
) AS t0
>>> from ibis_substrait.compiler.core import SubstraitCompiler
>>> compiler = SubstraitCompiler()
>>> proto = compiler.compile(expr)
