我怎样才能对变量或数组有多个值答案

【问题标题】：How can I had multiple values to a variable or an Array我怎样才能对变量或数组有多个值

【问题描述】：

我在下面有一个有效的查询。但是我需要使 OWNRSHP_ID 成为一个变量，我可以提供一个 OWNRSHP_ID 列表以逐个通过查询运行。

这个想法是有一个变量，我可以提供一个 ID 列表，查询将一个一个地运行。

我目前在 Teradata 中运行的这个 SQL。

【解决方案1】：

嗯，您目前确实在

中提供了一个 OWNRSHP_ID 列表

and line_corp.OWNRSHP_ID IN (10,55,75,110,65,85,95)

但假设您想将此列表作为逗号分隔的字符串传递，您可以应用 STRTOK_SPLI_TO_TABLE

and line_corp.OWNRSHP_ID IN
 (
   SELECT Cast(token AS INT) AS OWNRSHP_ID, tokennum
   FROM TABLE (StrTok_Split_To_Table(1, :OWNRSHP_IDs, ',')
        RETURNS (outkey INTEGER,
                 tokennum INTEGER,
                 token VARCHAR(20) CHARACTER SET Unicode)
              ) AS d 
 )

如果您将其移至派生表中，您甚至可以按输入字符串中 id 的位置进行排序：

...
Join IWR_VIEWS.MN_PROD_TYPE ptype
ON ptype.tsr_prd_typ = prodet.tsr_prd_typ
JOIN 
 (
   SELECT Cast(token AS INT) AS OWNRSHP_ID, tokennum
   FROM TABLE (StrTok_Split_To_Table(1, :OWNRSHP_IDs, ',')
        RETURNS (outkey INTEGER,
                 tokennum INTEGER,
                 token VARCHAR(20) CHARACTER SET Unicode)
              ) AS d 
 ) as dt
ON inv_corp.OWNRSHP_ID = dt.OWNRSHP_ID
...
ORDER BY tokennum;

当您对派生表进行外部联接时，您还可以为缺少的 ID 返回一个 NULL 行，但这可能需要对您的查询进行一些额外的更改。
