oracle sql语句传变量nvl((select sum(NETWEIGHT) from ST_WEIGHTETL jl, ST_FUELCOMMDATA ab where jl.DATANUM = ab.datanum and jl.siteid = ab.siteid and jl.orgid = ab.orgid
oracle sql语句传变量
nvl((select sum(NETWEIGHT)

如何把查询中设计到的系统时间的判断to_char(sysdate,'yyyy-mm-dd')换成一个时间类型的变量
急!

oracle sql语句传变量nvl((select sum(NETWEIGHT) from ST_WEIGHTETL jl, ST_FUELCOMMDATA ab where jl.DATANUM = ab.datanum and jl.siteid = ab.siteid and jl.orgid = ab.orgid
使用游标,单纯的SQL没法实现.

oracle sql语句传变量nvl((select sum(NETWEIGHT) from ST_WEIGHTETL jl, ST_FUELCOMMDATA ab where jl.DATANUM = ab.datanum and jl.siteid = ab.siteid and jl.orgid = ab.orgid oracle中的nvl函数 oracle sql 语句中where条件中 1=1 ORACLE中between…and...是SQL语句中的吗?还是仅限于SQL*PLUS里? oracle sql语句获取前两条数据select id,seq from hzds_admin where seq oracle 语句优化问题select nvl(sum(a.sl),0),nvl(sum(a.je),0)from tablea aleft join tableb bon a.zd = b.zdwhere a.zd2 in ('181','180','179','178','177','176','175')and nvl(b.zd3,'xx') = 'xx'类似这样的语句 zd、zd2是字段都有索引在p sql,oracle中语句执行顺序?sql中between 20 and 0 是否和0 and 20所查出的数据一样? SQL语句case whenselect trunc(date '2009-01-01','dd') as date_id, b.org_id as org_id, b.risk_id as risk_id, sum(a.planfee-nvl(c.payreffee,0)) , (case when to_char(statistic_date-payrefdate>=0) and to_char(st sql语句 decimal(18, oracle length函数select area_code,area_name from dict_area where length(area_code)=4 ORDER BY area_code asc这句sql语句中的where length(area_code)=4是什么意思? String sql=insert into tb_IPcount values(+this.times+,'+this.userip+','+this.nowdate+');为什么sql存储过程会有单引号中嵌套着双引号,第一个变量是int,第二三个都是String是Transact-SQL命令语句 sql语句中DISTINCT是什么意思 integer是什么意思?SQL语句中 SQL中 nvl（）coalesce（）decode（）这三个函数是不是递进包含关系?比如：select name,bonus from table where name='apple';name bonus----------------apple 空（我想让结果=0）以下语句都对吗?如果有问题请指出,1. sql.executeUpdate(condition3); jsp连oracle中sql.executeUpdate(condition3);什么意思? 麻烦大家用oracle给我建张表,sql语句： id int 主键,自增长 name Varchar(50) 学生姓名主要是自增长不主要是自增长不会 VB的grid控件 VB的grid控件 VB的grid控件我想把grid控件里面的数据（access）插入到另外一个数据库(oracle)里,用SQL语句怎么写其实也可以这样,在access数据库里的数据表,插入到oracle数据库的数据表, SQL语句中的（；）分号是什么意思?
