PL/SQL 中同一过程更新和插入的行数
Number of rows UPDATED and INSERTED from the same procedure in PL/SQL
我有一个程序执行某些字段的 INSERT INTO 然后 UPDATE（两者都在同一程序中），我正在使用来自@Clive Number of rows affected by an UPDATE in PL/SQL 的答案知道已更新到日志中的数据量，但它给我带来了总行数，而不仅仅是已更新的记录。
这是正确的了解方式吗？
我需要知道从 INSERT STATEMENT 中插入了多少行以及从 UPDATE STATEMENT.
中更新了多少行
我的查询：
CREATE OR REPLACE PROCEDURE OWNER.TABLE_NAME
AS

v_qtd_regs number := 0;
v_code number;
v_errm VARCHAR2(500);
start_time pls_integer;
end_time pls_integer;

BEGIN
proc_name := 'PRDWBI_CGA_D_COLUMNS';
start_time := dbms_utility.get_time;
DS_FUNCESP.PRDSBI_GRAVA_LOG( 'I', 'DataWarehouse', proc_name, 'Início Carga' );
-- INSERT INTO TABLE:
INSERT INTO OWNER.TABLE_NAME

COMMIT;
-- UPDATE SOME COLUMNS I NEED

SET (y.COLUMNS_NAME, y.COLUMN_NAME2) =

COMMIT;
--dbms_output.Put_line(i);
SELECT COUNT(1) INTO v_qtd_regs FROM OWNER.TABLE_NAME where LinData >= TRUNC(SYSDATE);
end_time := dbms_utility.get_time;
elapse_time := ((end_time - start_time)/100);
v_errm := SUBSTR(SQLERRM, 1 , 500);
DS_FUNCESP.PRDSBI_GRAVA_LOG('T', 'DataWarehouse', proc_name, v_errm, v_qtd_regs, elapse_time );

已编辑问题以显示真实示例：
我创建了一个 table 从 "SYS.DBA_TAB_COLUMNS" 中获取数据只是为了用作示例，如下所示：
CREATE TABLE "DW_FUNCESP"."D_TEST"
(
"ID_COLUMN" NUMBER(10,0) GENERATED BY DEFAULT ON NULL AS IDENTITY MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1
START WITH 1 CACHE 20 NOORDER NOCYCLE NOKEEP NOSCALE NOT NULL ENABLE,
"NM_OWNER" VARCHAR2(500 CHAR) NOT NULL ENABLE ,
"NM_TABLE" VARCHAR2(500 CHAR) NOT NULL ENABLE ,
"CD_COLUMN" NUMBER(20,0) NOT NULL ENABLE ,
"NM_COLUMN" VARCHAR2(500 CHAR) NOT NULL ENABLE ,
"DS_COLUMN" VARCHAR2(500 CHAR) NOT NULL ENABLE ,
"LINDATE" DATE DEFAULT SYSDATE NOT NULL ENABLE ,
"LINORIGIN" VARCHAR2(100 CHAR) NOT NULL ENABLE
)
然后我创建了一个程序来识别插入和更新的记录，如下所示：
CREATE OR REPLACE PROCEDURE DW_FUNCESP.PRDWBI_CGA_D_TEST
AS
-- variaveis de suporte as informações que deve gravar
rows_inserted integer;
rows_updated integer;
BEGIN
-- Insert Into table
INSERT INTO DW_Funcesp.D_TEST

LEFT JOIN DW_FUNCESP.D_TEST y

AND y.NM_TABLE = x.NM_TABLE
AND y.NM_COLUMN = x.NM_COLUMN

rows_inserted := sql%rowcount;
-- Update the table
UPDATE DW_FUNCESP.D_TEST z
SET (z.NM_COLUMN, z.DS_COLUMN, z.LINDATE) =

NVL(x.DS_COLUMN ,x.NM_COLUMN) AS DS_COLUMN ,

SELECT

rows_updated := sql%rowcount;
dbms_output.Put_line('inserted=>' || to_char(rows_inserted) || ', updated=>' || to_char(rows_updated));
COMMIT;
EXCEPTION

END;
所以我的第一个插入输出是：
inserted=>2821, updated=>2821
所以我选择了一个要更改的数据并更新了，我做了以下select来选择应该更新哪些数据以再次引入DBMS输出：
SELECT * FROM DW_FUNCESP.D_TEST WHERE NM_TABLE = 'D_TEST';
我在如图所示的专栏中发表评论，以引入更新：
COMMENT ON COLUMN DW_FUNCESP.D_TEST.LINORIGIN IS 'The origin of the data';
我再次运行程序，输出是：
inserted=>0, updated=>2821
该更新的结果：
你不应该在输出中只带 1 个更新数据吗，因为只有 1 个更新？不是所有行？
e.g.: inserted=>0, updated=>1
所以我的问题仍然存在，我问的对吗？是否有可能在相同的程序中获得此结果？是不是更新不正确（尽管已经更新了数据）？
尝试在每个 DML 后添加指令 i := SQL%rowcount;：
- INSERT 后插入的行数
- UPDATE 后更新的行数
您没有插入行和更新行。 SQL%rowcount 仅包含最后一个 select 或 DML 语句的行数。由于您仅在更新后才设置变量，因此您只能获得更新次数。如果你想要两者，那么你需要为每个单独的变量。
提示：无需在每个 DML 之后提交，实际上这通常被认为是一种非常糟糕的做法。您需要研究交易。基本思想是所有操作都成功完成或其中 none 成功完成。查找 ATOMIC 和 Atomicity。
所以你修改后的程序变成：
create or replace procedure owner.table_name
as
-- VARIABLE
v_qtd_regs number := 0;
v_code number;
v_errm varchar2(500);
start_time pls_integer;

start_time := dbms_utility.get_time;
ds_funcesp.prdsbi_grava_log( 'I', 'DataWarehouse', proc_name, 'Início Carga' );
insert into owner.table_name
(column_id, columns_name, column_name2)
(select 1 as column_id, 'TEST' as column_name, sysdate as column_name2 from dual);
rows_inserted := sql%rowcount;
update owner.table_name y
set (y.columns_name, y.column_name2) =
(select 'TEST2' as column_name, sysdate as column_name2 from dual x where x.column_id = y.column_id)

select count(1) into v_qtd_regs from owner.table_name where lindata >= trunc(sysdate);
end_time := dbms_utility.get_time;
elapse_time := ((end_time - start_time)/100);
v_errm := substr(sqlerrm, 1 , 500);
ds_funcesp.prdsbi_grava_log('T', 'DataWarehouse', proc_name, v_errm, v_qtd_regs, elapse_time );

end;
如果您有兴趣，我会使用 ORA_SCN 作为其他答案的建议 插入或更新了哪些 行。但是您只想知道有多少，所以我会将计数留给 Oracle（对于大量行可能会很耗时）。
请查看数据字典视图 USER_TAB_MODIFICATIONS（或 ALL_TAB_MODIFICATIONS，如果 table 在与过程不同的模式中。
CREATE TABLE d (
id NUMBER GENERATED ALWAYS AS IDENTITY,
dt DATE DEFAULT SYSDATE,
foo VARCHAR2(128 BYTE)
);
收集 table 统计数据将重置修改视图：
EXEC DBMS_STATS.GATHER_TABLE_STATS(NULL,'D');
现在在您的 INSERT 之后，修改视图将具有插入的行数：
INSERT INTO d(foo) SELECT object_name FROM all_objects;
67,141 rows inserted.
SELECT inserts, updates, deletes FROM user_tab_modifications WHERE table_name='D';
INSERTS UPDATES DELETES
67141 0 0
同样，在 UPDATE 之后，更新的行：
UPDATE d SET foo=lower(foo),dt=SYSDATE WHERE mod(id,10)=0;
6,714 rows updated.
SELECT inserts, updates, deletes FROM user_tab_modifications WHERE table_name='D';
