c# - SCOPE_IDENTITY() returns thousand number -

i have insert query below. however, scopeidentity not return 42, returns 1042.

this sql server table:

my code:

int masterid = 0;  using (sqlconnection cmd = new sqlconnection(connstring)) {     using (sqlcommand conn = cmd.createcommand())     {         conn.commandtext = "insert into[masterreportdata]([reportname],[caselist],[employeeid],[datetime]) values(@reportname, @caselist, @employeeid, @datetime) set @id = scope_identity()";          conn.parameters.add("@reportname", sqldbtype.varchar).value = reportname;         conn.parameters.add("@caselist", sqldbtype.varchar).value = caselist;         conn.parameters.add("@employeeid", sqldbtype.char).value = employeeid;         conn.parameters.add("@datetime", sqldbtype.datetime).value = datetime;         conn.parameters.add("@id", sqldbtype.int).direction = parameterdirection.output;          cmd.open();         conn.executenonquery();          masterid = convert.toint32(conn.parameters["@id"].value);         cmd.close();     } } 

have @ https://docs.microsoft.com/en-us/sql/t-sql/functions/scope-identity-transact-sql

the description says: returns last identity value inserted identity column in same scope. scope module: stored procedure, trigger, function, or batch. therefore, if 2 statements in same stored procedure, function, or batch, in same scope.

in words: returns last id , not next use. therefore can't use insert command that. can is:

configure id auto-increment id. run insert command , run select scope_identity() afterwards find out id used.
