composing an SQL directive, you use parameters to represent the values that need to be filled in, for example:

The parameter format for Microsoft SQL Server is the "@" character plus the parameter name, and SQL Server also supports anonymous parameter "?".
SELECT * from myTable WHERE MyID = @myID
INSERT into MyTable (C1, C2, C3, C4) VALUES (@c1, @c2, @c3, @c4)
