EXECUTE sp_executesql @statement = @sqlstr       
        PRINT @sqlstr  

It gives me error Procedure expects parameter '@statement' of type 'ntext/nchar/nvarchar',but when i change datatype @sqlstr AS nvarchar (max),error omitted,but it trancuate my query.Kindly help me to figure it out?

Answer 1

Here is one of the possible solution:

Convert your @sqlstr to varchar(max) and instead of EXECUTE sp_executesql, use EXECUTE(@strsql).In this fashion you got your complete print query and it will also execute your query.Hope that it helps.

Answer 2

sp_executesql takes NVARCHAR as parameter not VARCHAR, change varchar(max) to nvarchar(max) will fix the problem.

DECLARE @sqlstr AS  nvarchar (max)

Answer 3

Declare variable as a nvarchar type when you are using command exec sp_executesql.Above you used varchar for @sqlstr variable.
Eg.

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

Note:Dont use brackets in exec command
