PHP+MySql获取新添加记录的ID值

PHP+MySql获取新添加记录的ID值

1.假设字段名称为recordID

2.字段属性须设为:auto_increment

$newID = mysql_insert_id();

得到ID值


ASP获取即时ID值

ASP+Access2000

2.添加记录格式:Rs.Open table,Cn,1,3
注意模式为:1,3

3.newID = rs.Fields("recordID")

4.newID为刚添加的记录的ID值

ASP+SQL Server 2000

1.要获取的ID值字段属性必须设为:自动编号(我们假设字段名为recordID)

2.添加记录代码模式:

Cn.Execute"INSERT INTO table(field1,field2,...) VALUES("field1Value","field2Value",...)"

3.得到ID值

Set Rss = Cn.Execute("SELECT SCOPE_IDENTITY() as newIDValue FROM table")
'Rs.Open sqlStr,Cn,3,1
newID = Rss("newIDValue")

4.newID为刚添加的记录的ID值

5.附上取得ID值的三种方式:

/* 对于想要得到一个表中的最后一个插入操作所产生的ID的最好用IDENT_CURRENT('TBName')*/
INSERT INTO table(field1,field2,...) VALUES("field1Value","field2Value",...) SELECT IDENT_CURRENT('recordID') as newIDValue

/*对于马上使用的刚才插入的新记录ID用SCOPE_IDENTITY()是最合适的*/
INSERT INTO table(field1,field2,...) VALUES("field1Value","field2Value",...) SELECT SCOPE_IDENTITY() as newIDValue

/*对于想要得到一系列的操作中最后得到的那个自增的ID最好用@@IDENTITY*/
INSERT INTO table(field1,field2,...) VALUES("field1Value","field2Value",...) SELECT @@IDENTITY as newIDValu
