c# - Cannot convert varchar value to int in stored procedure in SQL Server -


i have stored procedure 

create procedure [dbo].[createnewticket]     (@practice_id varchar(40),     )   /* insert rows ticket table */ begin    declare @prctid int     select @prctid = 'select id practice_detail practice_name_description = ' + @practice_id + ';'  end   go

but whenever passing value c# stored procedure throwing error.

conversion failed when converting varchar value 'select id practice_detail practice_name_description = bankson pt- daniel (dba);' data type int.

can explain doing wrong?

try this

create procedure [dbo].[createnewticket] (  @practice_id varchar(40), ) /* insert rows ticket table */  begin declare @prctid int select @prctid = id practice_detail practice_name_description = @practice_id; end  go

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
