我做错了什么？请纠正我。
【问题讨论】：
-
您的动态 sql 缺少字符串片段之间的空格。例如，别名 'dsp' 后面没有空格，这将是一个
dspLEFT JOIN字符串，这是一个错误。添加空格。顺便说一句，MSSQL 允许多行字符串。 -
City 变量没有引号。我建议回到静态 sql 并写出你必须的条件。
and (@area = '' or dam.area = @area)。如果您仍想通过动态 sql 执行此操作，请在执行前添加print @sql。 -
... OFFSET '+@offset+ ...你的一侧有一根大绳子。另一边是一个整数。你正在尝试+他们在一起。int的优先级高于任何字符串类型，因此它试图将字符串转换为整数。您应该手动转换整数，但@Ivan 可能已经指出了其他问题。
