第一阶段Q.编写一个PL/SQL程序块以显示所给出雇员编号的雇员的详细信息。A. DECLARE erec emp%ROWTYPE;BEGIN SELECT

, ……); INSERT INTO 表名(字段名1, 字段名2, ……) SELECT (字段名1, 字段名2, ……) FROM 另外的表名;字符串类型的字段值必须用单引号括起来, 例如: ’GOOD DAY

另一种为 pcursor1: for loopcs1 as cousor1 cursor as select market_code as market_code from

.SELECTSPACE(10)FROMBSEMPMS;163.SECOND()返回一个数值的秒部分.SELECTSECOND(''18:34:32'')FROMBSEMPMS;164.RTRIM()删除字符串尾部的空格.SELECT
