请帮忙，

其实我的查询没问题，但问题是当插入10条记录中的第9条后，它说第10条记录有错误，但是如果我单独运行查询； 第一个查询有 9 条记录，那么 第二个查询只有 1 个，两者都没有错误。

以下是我使用的查询：

DECLARE @tblLkUp    VARCHAR(MAX),
        @tblLkUpCol VARCHAR(MAX),
        @strSQL     VARCHAR(MAX)

SET @tblLkUp = 
    (SELECT DISTINCT TOP 1 t.name AS TableName 
     FROM sys.tables t JOIN sys.indexes i ON i.index_id = t.schema_id  
     WHERE t.name LIKE '%$POS Lookup')

SET @tblLkUpCol = 
    (SELECT DISTINCT TOP 1 t.name AS TableName 
     FROM sys.tables t JOIN sys.indexes i ON i.index_id = t.schema_id  
     WHERE t.name LIKE '%$POS Lookup Columns')


SET @strSQL = 'IF (SELECT COUNT(*) FROM ' + QUOTENAME(@tblLkUp) + ' WHERE [Lookup ID] = ''ZOOMSPODTL'') = 0
                    BEGIN
                        INSERT INTO ' + QUOTENAME(@tblLkUp) + ' VALUES(DEFAULT, '''', ''ZOOMSPODTL'', ''Zoom Trans. SPO Line Details'', '''', 
                        ''ZOOM'', ''1'', ''99008981'', ''2'', ''10'', ''0'', ''0'', '''', ''0'', ''0'', ''0'', '''', '''', ''0'', ''0'',

                        IF (SELECT COUNT(*) FROM ' + QUOTENAME(@tblLkUpCol) + ' WHERE [Lookup ID] = ''ZOOMSPODTL'' AND [Table No_] = ''99008981'' AND [Column No_] = ''1'') = 0

最后做print @strSQL，分析已经建好的查询。
我这样做了print @strSQL Mikael，它说我在第 10 条记录中有错误..IF (SELECT COUNT(*) FROM ' + QUOTENAME(@tblLkUpCol) + ' WHERE [Lookup ID] = ''ZOOMSPODTL'' AND [Table No_] = ''99008981'' AND [Column No_] = ''10'') = 0 BEGIN INSERT INTO ' + QUOTENAME(@tblLkUpCol) + ' VALUES(DEFAULT, '''', ''ZOOMSPODTL'', ''99008981'', ''10'', ''10012750'', ''0'', ''0'', '

【解决方案1】：

您连接的字符串被截断为 4000 个字符。要解决此问题，您可以在作业中首先将cast('' as varchar(max)) 添加到@strSQL。

SET @strSQL = cast('' as varchar(max)) + 
              'IF (SELECT COUNT(*) FROM ' + QUOTENAME(@tblLkUp) + ' WHERE [Lookup ID] = ''ZOOMSPODTL'') = 0
                    BEGIN
                        INSERT INTO .......

^^，谢谢 Mikael，它可以工作.. 但是，你能告诉我这个CAST 以及它是如何工作的..:)
@ArgelJoseph - 嗯...我记得以前在某个地方看到过这个，但现在找不到了。我认为它与连接字符串时的类型转换有关。字符串文字不是varchar(max) 和quotename 也不是varchar(max)，因此结果不会是varchar(max)。添加cast('' as varchar(max)) 确保其中至少有一个字符串是varchar(max)，因此最终结果将是varchar(max)。
