Syntax error near @Top

T_Sql query statement

 

string sql = "select top @Top Id, PublishHouse from T_Publishers";

 

SqlParameter para = new SqlParameter("@Top", Top);

 

 

-> At runtime, an error is reported: Syntax error near @Top

 

-> Reason: @Top is a query condition, not a column in the table

 

-> Solution: replace @Top with string concatenation

 

StringBuilder strSql = new StringBuilder();

strSql.Append("select ");

if (Top > 0)

{

    strSql.Append(" top " + Top.ToString());

}

strSql.Append(" Id, PublishHouse");

 

strSql.Append(" from T_Publishers");
