Question

我想在动态查询中使用in运算符。目前，我需要有人指出正确的方向，如何构造撇号来分离值，以便它们不会干扰动态查询结构的撇号。这是问题的一部分，所以我需要知道的是如何放置分隔符，以便所有值都可以包含在动态查询格式中，而不是我现在的常规查询格式

WHERE ai.ImNumber != me.Company 
    AND me.ID IN ('value1','value2','value2','value3','value4','value5')'

我的查询

SET @SQLString = 'select me.EventID , ai.AggregateInfo, '''+@DateBegin+''' AS DateBegin, '''+@EDateEnd+''' AS DateEnd 
FROM tbl_MajorEarners me 
INNER JOIN tbl_currentearners e ON e.EventID = me.EventID 
INNER JOIN tbl_AggregateInfo ai ON ai.AggregateID = cs.ItemID 
WHERE ai.ImNumber != me.CompanyNUmber 
AND me.ID IN ('value1','value2','value2','value3','value4','value5')'

我认为这就是你要找的东西

SET @SQLString = 'select me.EventID , ai.AggregateInfo, ''@DateBegin'' AS DateBegin, ''@EDateEnd'' AS DateEnd 
FROM tbl_MajorEarners me 
INNER JOIN tbl_currentearners e ON e.EventID = me.EventID 
INNER JOIN tbl_AggregateInfo ai ON ai.AggregateID = cs.ItemID 
WHERE ai.ImNumber != me.CompanyNUmber 
AND me.ID IN (''value1'',''value2'',''value2'',''value3'',''value4'',''value5'')'

将@SqlString设置为

select me.EventID , ai.AggregateInfo, '@DateBegin' AS DateBegin, '@EDateEnd' AS DateEnd 
FROM tbl_MajorEarners me 
INNER JOIN tbl_currentearners e ON e.EventID = me.EventID 
INNER JOIN tbl_AggregateInfo ai ON ai.AggregateID = cs.ItemID 
WHERE ai.ImNumber != me.CompanyNUmber 
AND me.ID IN ('value1','value2','value2','value3','value4','value5')
