Question

目前我的控制文件为：

Load data
Infile '/.../../emp*.txt'
Append into table emp_load
When (emp_id <> 'emp_id')
Fields terminated by "," optionally enclosed by ' " '
Trailing nullcols
(Emp_id "TRIM(:EMP_ID)",
EMP_NAME "TRIM(:EMP_NAME)",
SAL "TRIM(:SAL)"
)

当前输入文件：

Emp_id,emp_name,sal
1,A,100
2,B,200

我现在有另一个要求，即输入文件将包含2个标题，并且类似于

/folder1/folder2/file1_<date>.csv
Emp_id,emp_name,sal
1,A, 100
2,B,200
...

同样我会有多个输入文件...

你能帮我解决这个场景的控制文件吗？

Answer 1

您需要SKIP = 2 OPTIONS子句。

OPTIONS (SKIP=2) 
Load data
Infile '/.../../emp*.txt'
Append into table emp_load
When (emp_id <> 'emp_id')
Fields terminated by "," optionally enclosed by ' " '
Trailing nullcols
(Emp_id "TRIM(:EMP_ID)",
EMP_NAME "TRIM(:EMP_NAME)",
SAL "TRIM(:SAL)"
)
