[英]Problem with a query in Postgres that I want to move to SQL Server
我现在需要在SQL Server上运行的postgres中有以下查询。 显然,我已经改变了每轮截断和基本的东西,但是主要是我在(c.cod_socio)tbl上选择不同的原则上有一个问题。 *由于SQL Server无法识别该语法。
select distinct on (c.cod_socio)
tbl.*, h.cod_oficina, h.cod_transaccion, h.num_transaccion,
h.num_sec, h.fec_movimiento
from
sgf_det_mov_his h
inner join
sgf_cuenta c on c.cod_producto = h.cod_producto and c.cod_cuenta = h.cod_cuenta
inner join
sgf_tran t on t.cod_transaccion = h.cod_transaccion and t.cod_oficina = h.cod_oficina and t.cod_tipo_transaccion in ('DA', 'DP','NC')
inner join
(select
sgf_cuenta.cod_socio,
sum(trunc(sgf_det_mov_his.val_efectivo, 0) + trunc(sgf_det_mov_his.val_cheques, 0)) as total
from
sgf_det_mov_his, sgf_cuenta, sgf_tran
where
sgf_cuenta.cod_producto = sgf_det_mov_his.cod_producto
and sgf_cuenta.cod_cuenta = sgf_det_mov_his.cod_cuenta
and sgf_det_mov_his.sts_mov = 'A'
and sgf_tran.cod_transaccion = sgf_det_mov_his.cod_transaccion
and sgf_tran.cod_oficina = sgf_det_mov_his.cod_oficina
and sgf_cuenta.cod_producto <> 2
and sgf_tran.cod_tipo_transaccion in ('DA', 'DP','NC')
and isnull(sgf_tran.cod_uaf, 0) > 0
and isnull(sgf_tran.cod_uaf, 0) not in (71)
and sgf_cuenta.cod_cuenta not in (select cod_cuenta
from sgf_credito
where sgf_credito.cod_producto = sgf_cuenta.cod_producto
and sgf_credito.cod_cuenta = sgf_cuenta.cod_cuenta
and sts_operacion in ('A'))
and date(sgf_det_mov_his.fec_movimiento) between '2015-01-01' and '2019-01-01'
group by
sgf_cuenta.cod_socio
having
sum(trunc(sgf_det_mov_his.val_efectivo,0) + trunc(sgf_det_mov_his.val_cheques,0)) >= 5000) tbl on tbl.cod_socio = c.cod_socio
where
date(h.fec_movimiento) between '2015-01-01' and '2019-01-01'
order by
c.cod_socio, h.fec_movimiento desc
distinct on (...)
仅仅保留了“第一行”,可以使用row_number() over(...)
和以下where clause
来模拟每个分区限制为一行。.请注意, distinct on
依赖于order by
子句决定“第一行”,因此您需要over clause
的等效条件。 还要注意,如果两个数据库之间的查询兼容性更高,则可以在PostgreSQL中使用相同的row_number方法。
