Nó mang lại cho tôi lỗi Thủ tục hy vọng tham số '@statement' loại ' ntext/nchar/nvarchar ', nhưng khi tôi thay đổi kiểu dữ liệu @sqlstr AS nvarchar (tối đa), lỗi bỏ qua, nhưng nó trancuate truy vấn của tôi.Kết quả giúp tôi tìm ra?

Answer 1

Đây là một trong những giải pháp khả thi:

Chuyển đổi của bạn @sqlstr-varchar(max) và thay vì EXECUTE sp_executesql, sử dụng EXECUTE(@strsql) .Tại thời trang này, bạn có hoàn toàn truy vấn in của bạn và nó cũng sẽ thực hiện truy vấn của bạn. Hy vọng rằng nó sẽ giúp.

Answer 2

sử dụng sp_executesql là tùy chọn rất tốt cho loại truy vấn này và nó không phải là rất thân thiện cho tiêm sql.

ví dụ:

DECLARE @sqlString nvarchar(500); 
DECLARE @paramDefinition nvarchar(500); 

DECLARE @sid = 12546; 

SET @sqlString = 'select * from SameTableBase S Where S.Id = @id'; 

EXECUTE sp_executesql @sqlString , @paramDefinition , @id = @sid 

Answer 3

Declare biến như một loại nvarchar khi bạn đang sử dụng lệnh exec sp_executesql .Above bạn sử dụng varchar cho @sqlstr biến.
Ví dụ:

Declare @Sqlstr nvarchar(max) 
SET @Sqlstr='...Your dynamic query...' 
exec sp_executesql @Sqlstr 

Lưu ý: Dont sử dụng dấu ngoặc trong lệnh exec

Answer 4

sp_executesql mất NVARCHAR như tham số không VARCHAR, thay đổi varchar(max) để nvarchar(max) sẽ khắc phục vấn đề.

DECLARE @sqlstr AS nvarchar (max)
