Conversion of Oracle TO_CHAR(datetime) with format string to MySQL
Conversion of Oracle TO_CHAR(datetime) with format string to MysqL
The Oracle TO_CHAR(datetime,fmt) function converts datetime values to a string in the format specified by the fmt option.
MysqL has the DATE_FORMAT function that allows datetime values converting to a string in the specified format.
sqlWays converts the Oracle TO_CHAR function to the MysqL DATE_FORMAT function and converts elements of format string from Oracle to corresponding specifier in MysqL as specified in the following table

.NET String.Format（）在数千个数字中添加逗号 - .NET String.Format () to add commas in thousands place for a number
问题：
I want to add a comma in the thousands place for a number. 我想在数千个数字中添加一个逗号。 String.Format() ? String.Format() 吗？
解决方案：
参考一： https://stackoom.com/question/RVy/NET-String-Format - 在数千个数字中添加逗号参考二： https://oldbug.net/q/RVy/NET-String-Format-to-add-commas-in-thousands-place-for-a-number
![Android Studio error: format not a string literal and no format arguments [-Werror=format-security]](http://www.gvkun.com/zb_users/upload/2025/04/4920657a-c854-456e-a3a5-93c0493fb3621744790842351.jpg "Android Studio error: format not a string literal and no format arguments [-Werror=format-security]")
Android Studio error: format not a string literal and no format arguments [-Werror=format-security]
使用 android studio, 如果编译 jni 过程出现如下错误：
error: format not a string literal and no format arguments [-Werror=format-security]
解决方法：
在你的 ndk 目录下修改 build/core/default-build-commands.mk
TARGET_FORMAT_STRING_CFLAGS := -Wformat -Werror=format-security
为
TARGET_FORMAT_STRING_CFLAGS := -Wformat #-Werror=format-security也就是把后面部分注释掉
Android 工程运行报错 Conversion to Dalvik format failed: Unable to execute dex: java.nio.BufferOv
如果eclipse中的项目前有个红叉叉，但是src下有没有任何提示错误但是又不能通过编译的时候如何找到项目工程的错误根源呢？方法如下：
打开eclipse的problem视图（如果关闭了可以在window－>show view下找到problem视图），然后在视图中就可以看到项目的根源问题何在了，呵呵。
言归正传，回到我遇到的问题上。
问题描述：
在导入一个Android App运行后提示如下错误：
Conversion to Dalvik format failed: Unable to execute dex: java.nio.BufferOverflowException. Check the Eclipse log for stack trace.
原因分析：
编译出错有可能是依赖jar缺失导致无法编译。
解决方法：
项目->properties->android->选择目标Android版。(一般高版本都可以搞定)
Android 项目出现 "Conversion to Dalvik format failed with error 1" 问题
Android 项目导入到新的 eclipse，adt 是 23.0.6，能运行。后来因为其他项目需求升级了新的 sdk，唯独 oa 项目运行不了，其他项目却能运行。
尝试把 sdk 换回来也不行。在网上找了解决方法都不行。
下面是打印出来的错误信息
