Remove password from git commit history

在github上传了带密码的文件的删除方法

在 GitHub上Push了带密码的文件，就算删掉文件，commit 历史还是残留的。

怎样删除commit历史呢？

方法:

使用 git filter-branch 可以替换 commit 历史，然后 --force push。

Oracle 的 Numer类型与 C# 数据类型对应关系

[.NET: Int32] = [Oracle:NUMBER(2)..NUMBER(9)*]

[.NET: Int64] = [Oracle:NUMBER(10)..NUMBER(18)*]

[.NET: Double] = [Oracle:NUMBER(x, 0)..NUMBER(x, 15)*]

[.NET: Double] = [Oracle: FLOAT]

[.NET: Decimal] = [Oracle:NUMBER]
