今天需要导一些数据，从excel导入到数据库中。
没有装现成的plsqldev，只能用sql*loader来弄了。
首先我把excel文件的内容转换成csv文件，以逗号分隔，在另存外excel文件的时候有那个选项。
然后我在目标库中创建了如下的表。
create table sql_summary(sql_time varchar2(100),sql_id varchar2(100),cpu_time varchar2(100),disk_time varchar2(100),exec_time varchar2(100),elapsed_s number);
数据类似下面的格式：
140320_165505,gk9u1b5j5702c,1.18E+10,111636718,691,25.14
140320_205539,gk9u1b5j5702c,1.18E+10,110500905,682,25.95
140321_005607,gk9u1b5j5702c,3049428380,29109514,181,22.07

140320_205539,gwpudzhp5zazc,2907558,629750,1,71.79
创建控制文件如下
LOAD DATA
INFILE a.txt
INTO TABLE sql_summary
FIELDS TERMINATED BY ","
TRAILING NULLCOLS
(sql_time,sql_id,cpu_time,disk_time,exec_time,elapsed_s)
然后调用sql*loader来导入了。粗放一点，其他的日志文件就不指定了。
sqlldr userid=n1/n1@xxxx control=a.ctl
也没有报错，就提示了一行信息。但是也不算错误，查看表里，没有数据
DUM1102 /oravl01/oracle> sqlldr userid=n1/n1@xxxx control='/oravl01/oracle/a.ctl'

Commit point reached - logical record count 64
对于上面的信息，查了下，可以在控制文件中加入这个选项来可控制commit的频度。最大目前是165.
#OPTIONS (ROWS=100)
设置了以后还是不行。
最后百思不得其解，看看文件的内容吧，vi 一看，原来是dos格式的问题
140314_124138,007yxsxdz7p0h,13721913,165027,1,30.93^M

140315_204420,007yxsxdz7p0h,10631384,165132,1,20.66^M
用dosux或者dos2unix格式化一把。
重新试一次。数据算是导入了。：）
脚本如下。
LOAD DATA
INTO TABLE sql_summary
FIELDS TERMINATED BY ","
TRAILING NULLCOLS
(sql_time,sql_id,cpu_time,disk_time,exec_time,elapsed_s)
sqlldr userid=n1/n1@xxxx control=a.ctl data=a.data
DUM1102 /oravl01/oracle> sqlldr userid=n1/n1@xxxx control=a.ctl data=a.data
