sql - PLS-00428:此SELECT语句中应有一个INTO子句

Question

我想将Rownum存储为变量，而不是使用昂贵的Join。
我需要从Select语句中获取此信息，因为Rownum在各种环境下都会有所不同，因此它不能是代码中的文字字符串。

对于上下文，此查询在Oracle Siebel CRM架构上执行，并检索某些具有特定类型和属性的产品。

我尝试在Toad和Oracle SQL Developer中使用以下SQL代码，但是出现以下错误:

PLS-00428: an INTO clause is expected in this SELECT statement

这是代码

    DECLARE
    PROD_ROW_ID varchar(10) := NULL;
BEGIN
    SELECT ROW_ID INTO VIS_ROW_ID FROM SIEBEL.S_PROD_INT WHERE PART_NUM = 'S0146404';

    BEGIN
        SELECT rtrim(VIS.SERIAL_NUM) || ',' || rtrim(PLANID.DESC_TEXT) || ',' ||
               CASE
               WHEN PLANID.HIGH = 'TEST123'
               THEN
                   CASE
                   WHEN to_date(PROD.START_DATE) + 30 > sysdate
                   THEN 'Y'
                   ELSE 'N'
                   END
               ELSE 'N'
               END
               || ',' || 'GB' || ',' ||
               rtrim(to_char(PROD.START_DATE, 'YYYY-MM-DD'))
        FROM SIEBEL.S_LST_OF_VAL PLANID
            INNER JOIN SIEBEL.S_PROD_INT PROD
                ON PROD.PART_NUM = PLANID.VAL
            INNER JOIN SIEBEL.S_ASSET NETFLIX
                ON PROD.PROD_ID = PROD.ROW_ID
            INNER JOIN SIEBEL.S_ASSET VIS
                ON VIS.PROM_INTEG_ID = PROD.PROM_INTEG_ID
            INNER JOIN SIEBEL.S_PROD_INT VISPROD
                ON VIS.PROD_ID = VISPROD.ROW_ID
        WHERE PLANID.TYPE = 'Test Plan'
              AND PLANID.ACTIVE_FLG = 'Y'
              AND VISPROD.PART_NUM = VIS_ROW_ID
              AND PROD.STATUS_CD = 'Active'
              AND VIS.SERIAL_NUM IS NOT NULL;
    END;
END;

在PLSQL块中，必须将选择语句的列分配给变量，在SQL语句中不是这种情况。

第二个BEGIN的SQL语句没有INTO子句，这导致了错误。

DECLARE
   PROD_ROW_ID   VARCHAR (10) := NULL;
   VIS_ROW_ID    NUMBER;
   DSC           VARCHAR (512);
BEGIN
   SELECT ROW_ID
     INTO VIS_ROW_ID
     FROM SIEBEL.S_PROD_INT
    WHERE PART_NUM = 'S0146404';

   BEGIN
      SELECT    RTRIM (VIS.SERIAL_NUM)
             || ','
             || RTRIM (PLANID.DESC_TEXT)
             || ','
             || CASE
                   WHEN PLANID.HIGH = 'TEST123'
                   THEN
                      CASE
                         WHEN TO_DATE (PROD.START_DATE) + 30 > SYSDATE
                         THEN
                            'Y'
                         ELSE
                            'N'
                      END
                   ELSE
                      'N'
                END
             || ','
             || 'GB'
             || ','
             || RTRIM (TO_CHAR (PROD.START_DATE, 'YYYY-MM-DD'))
        INTO DSC
        FROM SIEBEL.S_LST_OF_VAL PLANID
             INNER JOIN SIEBEL.S_PROD_INT PROD
                ON PROD.PART_NUM = PLANID.VAL
             INNER JOIN SIEBEL.S_ASSET NETFLIX
                ON PROD.PROD_ID = PROD.ROW_ID
             INNER JOIN SIEBEL.S_ASSET VIS
                ON VIS.PROM_INTEG_ID = PROD.PROM_INTEG_ID
             INNER JOIN SIEBEL.S_PROD_INT VISPROD
                ON VIS.PROD_ID = VISPROD.ROW_ID
       WHERE     PLANID.TYPE = 'Test Plan'
             AND PLANID.ACTIVE_FLG = 'Y'
             AND VISPROD.PART_NUM = VIS_ROW_ID
             AND PROD.STATUS_CD = 'Active'
             AND VIS.SERIAL_NUM IS NOT NULL;
   END;
END;
