var exprList = new ExprList(); var expression = Expr.Column("id"); exprList.Add(expression);
var connection = new SqliteConnection("Data Source=mydatabase.db"); connection.Open(); var command = connection.CreateCommand(); command.CommandText = "SELECT * FROM mytable WHERE id IN @values"; var parameters = new SqliteParameter("@values", DbType.String); var expressionList = new ExprList(); expressionList.Add(Expr.Literal("1"), Expr.Literal("2"), Expr.Literal("3")); parameters.SetValue(expressionList); command.Parameters.Add(parameters); var reader = command.ExecuteReader(); while (reader.Read()) { // process the result set }In this example, we create a SQL query that selects rows from a table named 'mytable' where the 'id' column is in a list of values provided as a parameter. The parameter is set to an ExprList object that contains three expressions representing the values '1', '2', and '3'. Overall, ExprList is a useful class for building and manipulating lists of expressions in C# applications that interact with SQL databases.
