添加分隔線

Question

我目前有一個Storedproc t hat正在返回值，以便在asp.net中綁定一個gridview。我想要做的一件事是將兩個字段合併爲一個，但我似乎無法使其工作。

這裏是我的存儲過程

DECLARE @SQL VARCHAR(MAX); 

BEGIN 
SET @SQL = N'SELECT SYSTEM AS ''System'' 
      , ENTN AS ''Entity'' 
      , MED_CTR AS ''Medical Center'' 
      , MED_CTR_LEVEL AS ''Medical Center Level'' 
      , DEPT_ID AS ''Department ID'' 
    FROM V_ROLLUP_SYSTEM_DESC_REV1 
    WHERE (DEPT_ID = '+CONVERT(VARCHAR,@DEPTCODE)+') 
     AND SYSTEM IN ('+@SYS+')' 
PRINT(@SQL) 
EXEC(@SQL) 

所以我想MED_CTR與MED_CTR_LEVEL由「/」分隔，並標記爲醫療中心/水平結合起來。我似乎不能將它結合到目前爲止，因爲我嘗試在其中添加「/」的每種方法都沒有給我返回任何內容。

這應該工作：

SET @SQL = N'SELECT SYSTEM AS [System] 
      , ENTN AS [Entity] 
      , (MED_CTR +''/''+ MED_CTR_LEVEL) as [Medical Center/ Level] 
      , DEPT_ID AS [Department ID] 
    FROM V_ROLLUP_SYSTEM_DESC_REV1 
    WHERE (DEPT_ID = '+CONVERT(VARCHAR,@DEPTCODE)+') 
     AND SYSTEM IN ('+@SYS+')' 

如果你想確保2列CONCAT總是成功，你可以這樣做：

SET @SQL = N'SELECT SYSTEM AS [System] 
      , ENTN AS [Entity] 
      , ISNULL(MED_CTR,''N/A'') +''/''+ ISNULL(MED_CTR_LEVEL,''N/A'')) as [Medical Center/ Level] 
      , DEPT_ID AS [Department ID] 
    FROM V_ROLLUP_SYSTEM_DESC_REV1 
    WHERE (DEPT_ID = '+CONVERT(VARCHAR,@DEPTCODE)+') 
     AND SYSTEM IN ('+@SYS+')'
