The number of row value expressions in the INSERT statement exceeds the maximum allowed number of 1000 row values One of INSERT INTO script is written as following.

INSERT INTO tableName (Column1, Column2,....) VALUES (value1, Value2,...), (value1, Value2,...),....


Following is the error we are facing on parsing above insert statement


  Msg 10738, Level 15, State 1, Line 1007
  The number of row value expressions in the INSERT statement exceeds the maximum allowed number of 1000 row values.


My simple question is that, Can we change 1000 values limit ?
No. This hard-coded restriction exists for good reasons related to possible excessive query plan compilation time. You can workaround it by listing the VALUES clauses in a CTE, then INSERTing from the CTE, but I do not recommend it.
Break the INSERT statement up into VALUES clauses of &lt;= 1,000 lines each as a workaround, or use an alternative data loading method such as bcp or BULK INSERT. The fundamental issue may be addressed in a future version of SQL Server. See also Martin Smith's great answer on Stack Overflow.
