Question

感谢你们这些天的帮助，我希望我能帮助至少一个人，但我不会在这里恭喜你们。

当我尝试检查数据库上某些进程的状态时，我遇到了问题

我提出了一个问题：

DECLARE 
CLAVES varchar(12);
FECHA   date;

BEGIN

FECHA    := TO_DATE('16/10/2015','DD/MM/YYYY');
FOR KEYS IN (
        SELECT  SKEY,
                SUBSTR(RPAD(COD.SCOMMAND,43),41)    PROD 
        FROM    INSUDB.BATCH_JOB COD,
                INSUDB.BATCH_PROCESS PRO
        WHERE   COD.NUSERCODE = '3345'
        AND     COD.NBATCH = PRO.NBATCH
        AND     COD.NUSERSUBMIT = COD.NUSERCODE
        AND     TRUNC(COD.DSUBMIT) = TO_DATE ('16/10/2015', 'DD/MM/YYYY')
        AND     PRO.SCODISPL    = 'VIL7002'
        ORDER BY COD.DSUBMIT ASC 

    )LOOP
        CLAVES :=   TRIM(TO_CHAR(KEYS.SKEY));

        BEGIN
            SELECT  '01 - EJEC' " ", 
                    NPRODUCT PRODUCTO, 
                    COUNT(*) CONTAR,
                    TO_CHAR(NVL(TRUNC(MOD((MAX(DCOMPDATE) - MIN(DCOMPDATE))*24,24 )),0)) ||' HRS. '|| 
                    TO_CHAR(NVL(TRUNC(MOD((MAX(DCOMPDATE) - MIN(DCOMPDATE))*24*60,60)),0)) ||' MIN. '|| 
                    TO_CHAR(NVL(TRUNC(MOD((MAX(DCOMPDATE) - MIN(DCOMPDATE))*24*60*60,60)),0)) ||' SEG.' TIEMPO,
                    MIN(DCOMPDATE) ,
                    MAX(DCOMPDATE) 
            FROM    TIMETMP.TMP_VIL7002
            WHERE   SKEY = CLAVES
            AND     NSTATUS = 1
            group by nproduct
            UNION
            SELECT  '02 - PEND' COL, 
                    null, 
                    COUNT(*), 
                    NULL, 
                    NULL, 
                    NULL
            FROM    TIMETMP.TMP_VIL7002
            WHERE   SKEY = CLAVES
            AND     NSTATUS <> 1
            UNION
            SELECT  '03 - ERR ' COL, 
                    null,
                    COUNT(*), 
                    NULL, 
                    NULL, 
                    NULL
            FROM    TIMETMP.TMP_VIL7002
            WHERE   SKEY = CLAVES
            AND     NSTATUS = 3
            UNION
            SELECT  '04 - TOTAL' COL, 
                    null, 
                    COUNT(*), 
                    NULL, 
                    NULL, 
                    NULL
            FROM    TIMETMP.TMP_VIL7002
            WHERE   SKEY = CLAVES;
        END;
    END LOOP;
END;

这只会给我下一条错误消息

END;
Error at line 1
ORA-06550: línea 24, columna 17:
PLS-00428: an INTO clause is expected in this SELECT statement

Answer 1

这正是消息所说的。如果在PLSQL中执行select语句，则必须对结果执行某些操作。您可以创建一个for循环来迭代它（就像使用第一个查询一样），或者添加一个into子句，在该子句中为查询中的每个列指定一个PLSQL变量。这就是PLSQL在执行内部SQL语句之类的语句时所期望的。

就像现在一样，它只是执行大内部查询而不对其结果做任何事情。而且由于这很愚蠢，PLSQL不允许这样做。

Answer 2

每当你在PL / SQL中编写SELECT语句时，你应该使用SELECT INTO语句，这样结果就可以了。

您可以在此处了解如何制作SELECT INTO：

Answer 3

所以，我最终解决了我的问题，使用此查询并且不使用过程

SELECT  SKEY,
    SUBSTR(RPAD(COD.SCOMMAND,43),41)    PROD,
    SUBSTR(RPAD(COD.SCOMMAND,67),66)||'/'||SUBSTR(RPAD(COD.SCOMMAND,65),64)||'/'||SUBSTR(RPAD(COD.SCOMMAND,63),60)    FECHA, 
    (SELECT COUNT(*) FROM TIMETMP.TMP_VIL7002 TMP WHERE TMP.SKEY = COD.SKEY AND NSTATUS = 1) EJECUTADOS,
    (SELECT COUNT(*) FROM TIMETMP.TMP_VIL7002 TMP WHERE TMP.SKEY = COD.SKEY AND NSTATUS <> 1) PENDIENTES,
    (SELECT COUNT(*) FROM TIMETMP.TMP_VIL7002 TMP WHERE TMP.SKEY = COD.SKEY AND NSTATUS = 3) ERRORES,
    (SELECT COUNT(*) FROM TIMETMP.TMP_VIL7002 TMP WHERE TMP.SKEY = COD.SKEY ) TOTAL,
    (SELECT MIN(DCOMPDATE) FROM TIMETMP.TMP_VIL7002 TMP WHERE TMP.SKEY = COD.SKEY ) INICIO,
    (SELECT MAX(DCOMPDATE) FROM TIMETMP.TMP_VIL7002 TMP WHERE TMP.SKEY = COD.SKEY ) TERMINO  
FROM    INSUDB.BATCH_JOB COD,
    INSUDB.BATCH_PROCESS PRO
WHERE   COD.NUSERCODE = '3345'
AND     COD.NBATCH = PRO.NBATCH
AND     COD.NUSERSUBMIT = COD.NUSERCODE
AND     TRUNC(COD.DSUBMIT) = TO_DATE ('18/10/2015', 'DD/MM/YYYY') -- unico parametro a cambiar es la fecha de ejecucion
AND     PRO.SCODISPL    = 'VIL7002'
ORDER BY COD.DSUBMIT ASC
