从Oracle 8i开始,EXP工具支持使用查询子句对特定表的部分数据执行导出,这个功能是通过EXP的query参数来实现的,在使用过程中可能最常见的错误是: LRM-00112: multiplevalues not allowed for parameter 'query' EXP-00019: failed toprocess parameters, type 'EXP HELP=Y' for help EXP-00000: Exportterminated unsuc...
但insert all into中子查询不支持使用序列,如下操作,提示错误, SQL> insert all 2 into a1(id, a, b, c, d) values (seq_a1.nextval, 'a', 'a', 'a', 'a') 3 into a1(id, a, b, c, d) values (seq_a1.nextval, 'b', 'b', 'b', 'b') 4 select seq_a1.nextval, a, b, ...

那我们在Oracle中,怎么通过一个insert语句批量插入数据呢? INSERTALL INTO A(field_1,field_2)VALUES (value_1,value_2) INTO A(field_1,field_2)VALUES (value_3,value_4) INTO A(field_1,field_2)VALUES (value_5,value_6) SELECT1FROM DUAL; ...
再次执行insert all into,则会插入4条记录,因为子查询,返回2条记录, SQL> insert all2intoa1(id, a, b, c, d)values(1,'a','a','a','a')3intoa1(id, a, b, c, d)values(2,'b','b','b','b')4selectid, a, b, c, dfroma1;4rows created. ...
â Value Suppress suppresses duplicate values from displaying more than once. â Sort Ascending sorts the column in ascending order. â Sort Descending sorts the column in descending order. â Group adds a group header and footer for the column. â ...

$sql = "INSERT INTO ORDER_ITEMS (order_line_id,order_id,item_id) VALUES (ORDER_LINE_SQ.nextval,".$order_id.",".$item.")"; $stmt = oci_parse($db,$sql); oci_execute($stmt); } While this approach is a perfectly fine way to handle multiple inserts (except for starting a transac...
insert into user(name,address,age)values(#{name,jdbcType=VARCHAR},#{address,jdbcType=VARCHAR},#{age,jdbcType=NUMERIC},) 2、第二种方式,MyBatis-config.xml 中设置当JDBC类型为空值时,要指定的值得,默认为OTHER,我们指定为NULL就好了(注意是大写的NULL)。
