Introduction xorm is a simple and powerful Go language ORM library, through which database operations can be made very easy. This library is a customized and enhanced version based on the original xorm, which provides xorm with configuration files similar to ibatis and dynamic SQL support, and supports AcitveRecord operations. github address: https://github.com/armingli/xorm //Installation go […]

Xorm combat – structure mapping to achieve database operations (including export database scripts)
Download import framework To use the orm framework in the go language, you need to download the framework first and introduce: // Install toolkit go get xorm.io/xorm //Install the database driver (mysql here) go get -u github.com/go-sql-driver/mysql //Introduce frame import ( “gorm.io/driver/mysql” “gorm.io/gorm” ) Database construction For database construction, xorm also provides the function of […]

QxOrm uses Sql statements for database operations
Article directory QxOrm uses Sql statement Use qx::QxSqlQuery Use standard SQL or stored procedures Use qx::dao::execute_query() to execute sql qx::dao::call_query() Execute stored procedure QxOrm uses Sql statement Previously introduced the addition, deletion, modification and query of purely using QxOrm, and then introduced the use of QxOrm to execute sql statements. This part is also necessary. […]

xor (vector+dictionary tree)
The main idea of the topic gives a length of no no sequence of n A A A, give another integer x x x, a subsequence is a qualified subsequence if it satisfies the following conditions: The XOR result of any two numbers in the sequence is greater than or equal to x x x […]
Compiling Xorg on Ubuntu 22.04
Because I want to debug the Xorg code and determine whether it is a problem with the X client, I need to compile the Xorg code. step: 1 Download the source code of xorg (Reference: ow to Install xorg-server-source) jenkins@rico-fast:~$ sudo apt-get update –fix-missing jenkins@rico-fast:~$ sudo apt-get -y install xorg-server-source jenkins@rico-fast:~$ cp /usr/src/xorg-server.tar.xz . jenkins@rico-fast:~$ […]
Lumos framework implements XOR problem modeling
Lumos framework implements XOR problem modeling Through the feedforward neural network, construct the XOR function model. Use [Lumos](LumosNet (github.com)) deep learning framework to realize neural network construction, training and testing Exclusive OR (XOR) The exclusive OR function XOR is the operation of two binary numbers a and b. If and only if one of them […]
#126. Path counting, #289. Maximum and ascending subsequence, #498. Add one, #496. Jumping, #500. XOR and OR, #502. 01 sequence, stack sequence judgment
#126. Path Count There is an n×nn×n grid, some grids are passable, and some grids are obstacles. At the beginning you are in the upper left corner, you can go down or to the right every step, and ask how many ways to get to the lower right corner. Since the answer is large, output […]
