Oracle table Structure transformation SQL Server table structure script

In auditing, it is sometimes necessary to modify the table structure of Oracle and then create the table structure in SQL Server, and then import the data into SQL Server, in the process of modifying the table structure. Manual modification, the most stupid method, or using the tool UE batch modification, still do the method, The most convenient way is to use a script swish, all changed well:

VI Parameter.ini
#sysType---1:linux;others:windows
Systype=1
#readFiledir is OldFile
Readfiledir=/root/tmpmycnf/dbquery/yoon/oldfile
#writeFiledir is New File
Writefiledir=/root/tmpmycnf/dbquery/yoon/newfile
