Question

Declare 
v_cardRecord card%ROWTYPE;
v_cardRecords IS TABLE OF card%ROWTYPE;
i BINARY_INTEGER;
Begin
select nt.name, nd.name, ct.name, ps.name, count(c.cardid) BULK COLLECT INTO v_cardRecords
from cardtype ct, card c, node n, nodetype nt, nodedef nd, provisionstatus ps
where ct.name in ('SRA AMP', 'XLA AMP', 'SAM', 'ESAM')
and ct.cardtypeid = c.card2cardtype
and c.card2node = n.nodeid
and n.node2nodetype = nt.nodetypeid
and n.node2nodedef = nd.nodedefid
and c.card2provisionstatus = ps.provisionstatusid
group by nt.name, nd.name, ct.name, ps.name;

错误＆＃34; PLS-00103，遇到＆＃34; IS＆＃34;当预计会出现以下情况之一。

2-之后，我想将v_cardRecords存储在另一个表中。

我该怎么办？

Answer 1

如果您只想从多个表中选择数据然后将结果插入另一个表中，那么就效率而言，最佳方法是

INSERT INTO <table_name>
(<column>
,<column>
)
SELECT
FROM
;

但是，如果您需要使用过程逻辑转换数据，那么批量处理肯定是可行的方法。由于多种原因，您的方法无效：

您正在批量收集不匹配的记录结构您的查询
您的查询包含多个具有相同别名的列
批量收集中的语法错误

以下内容更接近您的要求：

DECLARE 

  CURSOR C_get_cards
  IS
    SELECT 
     nt.name     nt_name
    ,nd.name     nd_name
    ,ct.name     ct_name
    ,ps.name     ps_name
    ,count(c.cardid) 
    FROM cardtype ct, card c, node n, nodetype nt, nodedef nd, provisionstatus ps
    WHERE ct.name in ('SRA AMP', 'XLA AMP', 'SAM', 'ESAM')
    AND ct.cardtypeid = c.card2cardtype
    AND c.card2node = n.nodeid
    AND n.node2nodetype = nt.nodetypeid
    AND n.node2nodedef = nd.nodedefid
    AND c.card2provisionstatus = ps.provisionstatusid
    GROUP by nt.name, nd.name, ct.name, ps.name
  ;
  TYPE cards_TAB_TYPE IS TABLE OF C_get_cards%ROWTYPE INDEX BY BINARY_INTEGER ;
  T_card_details              cards_TAB_TYPE ;

BEGIN
  OPEN C_get_cards ;

  LOOP

    FETCH C_get_cards
      BULK COLLECT INTO T_card_details
      LIMIT 250
    ;

    FOR i IN 1..T_card_details.COUNT LOOP
      NULL ; 
      -- <transform / work on data here>  
    END LOOP ;

    FORALL i IN T_card_details.FIRST..T_card_details.LAST 
      INSERT INTO table_name
       (column1
       ,column2
       )
       VALUES
       (T_card_details(i).nt_name 
       ,T_card_details(i).nd_name 
       )
    ;

    EXIT WHEN T_card_details.COUNT = 0 ;

  END LOOP ;
END ;

存储查询的输出，该查询在Oracle中的单个变量中返回多行
