Question

下面我展示了我到目前为止所尝试的内容。

我使用游标进行SQL Server while循环。我的查询中的问题与以下代码一致：

SELECT NAME 
FROM TRDR 
WHERE TRDR = MyCursor.TRDR

我不确定如何从光标@MyCursor

获取值

DECLARE @MyCursor CURSOR;
DECLARE @MyField INT;
DECLARE @FromDate DATE;
DECLARE @ToDate DATE;
DECLARE @Serie INT;
DECLARE @Sosource INT;
DECLARE @trdr INT;

SET @FromDate = '20160901';
SET @ToDate = '20160930';
SET @Serie = 4700;
SET @Sosource = 1416;
SET @trdr = 2835;

BEGIN
    SET @MyCursor = CURSOR FOR
        SELECT TOP 1000 FINDOC, TRDR 
        FROM FINDOC
        WHERE SOSOURCE = @Sosource 
          AND TRNDATE >= @FromDate 
          AND TRNDATE <= @ToDate 
          AND SERIES = @Serie 
          AND TRDR = 2835
END

OPEN @MyCursor

FETCH NEXT FROM @MyCursor INTO @MyField

WHILE @@FETCH_STATUS = 0
BEGIN
    SELECT NAME 
    FROM TRDR 
    WHERE TRDR = MyCursor.TRDR
    FOR XML PATH('GrpHdr'), ROOT ('CstmrCdtTrfInitn')

    FETCH NEXT FROM @MyCursor INTO @MyField 
END; 

CLOSE @MyCursor ;
DEALLOCATE @MyCursor;

预期输出应如下：

<CstmrCdtTrfInitn>
   <GrpHdr>
       <name>Chris</name>
   </GrpHdr>
   <GrpHdr>
       <name>Martin</name>
   </GrpHdr>
   <GrpHdr>
       <name>John</name>
   </GrpHdr>
   <GrpHdr>
       <name>George</name>
   </GrpHdr>
   <GrpHdr>
       <name>Michael</name>
   </GrpHdr>
</CstmrCdtTrfInitn>

更新您真正想要的结果。试试这个，看看是否有效。

   Select TOP 1000 T.Name
            FROM FINDOC F
            JOIN TRDR T ON F.TRDR = T.TRDR
            WHERE F.SOSOURCE = @Sosource 
              AND F.TRNDATE >= @FromDate 
              AND F.TRNDATE <= @ToDate 
              AND F.SERIES = @Serie 
              AND F.TRDR = 2835 
        FOR XML PATH('GrpHdr'), ROOT ('CstmrCdtTrfInitn')

SQL Server：While循环使用Cursor并导出XML文件
