Exception: Too many parameters were provided in this RPC request. The maximum is 2100.

[Microsoft][SQL Native Client][SQL Server]The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Too many parameters were provided in this RPC request. The maximum is 2100.

SQL语句的报错

如果是SELECT查询OR条件语句形如：SELECT * FROM tablename WHERE x1 OR x2 OR x3 OR x4 OR ... OR x2101，OR条件个数超过2100就会报错，可以改为UNION ALL。

如果是SELECT查询IN条件语句形如： SELECT * FROM tablename WHERE columnname IN (1,2,3,4,5, ........ , 2101 )，IN参数个数超过2100，会报上面的错误。可以创建临时表，将这些数据写入临时表，再关联。

--Create new table   
Create Table temp (myvalues uniqueidentifier)

-- Join new table with your table   
SELECT t1.*    
FROM tablename t1    
JOIN temp t2 
ON t1.myvalues = t2.myvalues

存储过程和函数的报错

对于存储过程和函数，参数最大个数为2100
