Record Class NamedSQLListParameter

java.lang.Object
java.lang.Record
cool.scx.jdbc.sql.NamedSQLListParameter
public record NamedSQLListParameter(Collection<?> values) extends Record

代表一种特殊的 SQL 参数类型, 用于处理带有列表形式的命名参数.

通常用于 SQL 查询中, 如 IN 子句 例如: `SELECT * FROM table WHERE field IN (:values)`` 该类允许用户将多个值传递给 SQL 查询, 而不是仅仅传递一个单一值.

注意: 此参数类型只能用于带有命名参数的 SQL 查询, 且仅适用于 NamedSQL.

示例:

var inList = new NamedSQLListParameter(1, 2, 3, 4);

对应 SQL 查询: SELECT * FROM table WHERE field IN (:inList)
