我想将Rownum存储为变量,而不是使用昂贵的Join.
我需要从Select语句中获取这个,因为Rownum将在各种环境中不同,因此它不能是代码中的字面字符串.
我需要从Select语句中获取这个,因为Rownum将在各种环境中不同,因此它不能是代码中的字面字符串.
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,但是我收到以下错误：
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;

解决方法
在PLsql块中,必须将select语句中的列分配给与sql语句不同的变量.
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;
