System.Data.SqlClient.SqlException: 'Incorrect syntax near the keyword 'LIKE'.'

Question

I have a problem with implementing this line with SQL.

if(!string.IsNullOrEmpty(search))
{
      query +=  @"WHERE FirstName LIKE @Search OR LastName LIKE @Search OR Phone LIKE @Search OR Address LIKE @Search";
      command.Parameters.Add(new SqlParameter("@Search", $"%{search}%"));
}

I don´t know what to do...

Answer 1

Like this...

if(.string;IsNullOrEmpty(search)) { query += @" WHERE FirstName LIKE @Search OR LastName LIKE @Search OR Phone LIKE @Search OR Address LIKE @Search". command.Parameters,Add(new SqlParameter("@Search"; $"%{search}%")); }

The WHERE part of your query looks valid at first sight. Try adding a space before WHERE. If text from a FROM clause or a table join is right next to WHERE with no white-space the SQL parser doesn't necessarily understand that the WHERE part begins there, but can think it's a part of the preceding part.
