Basic applications of regular expressions
Regular expressions are often used to verify whether a known string meets specific requirements, such as whether it is a number, whether it is an all-lowercase string, and so on. A regular expression (regex for short) is a string used to describe a pattern that matches a set of strings. Regular expressions can be used […]
PostgreSQL execution engine – execScan projection filtering and predicate filtering
The previous blog PostgreSQL database query execution – SeqScan node execution introduced the execution of the SeqScan node. This blog mainly focuses on describing the execution of execScan predicate filtering. This code provides support for generalized relation scanning. ExecScan is passed a node and a pointer to a function to “do the right thing” and […]
c++ object-oriented large number calculation calculation of high-precision pi
A 32-bit integer computer can represent integers in the range approximately -2 billion to +2 billion. There is generally no problem operating within this range, but some applications may need to use integers outside the above range. C++ can meet this need by creating powerful new data types. According to the suffix, define a large […]
System integration router OSPF dynamic and comprehensive routing configuration
Experimental tasks: Contents and characteristics of dynamic routing protocols RIP and OSPF For dynamic routing RIP and OSPF experiments, establish a topology pc1>>R1>>R2>>R3>>pc2, so that pc1 and pc2 can communicate with each other, and configure the silent interface on the PC side. Familiar with configuring inter-vlan routing technology: multilayer switch virtual interface SVI and single-arm […]
Postgresql source code (103) expression ExprContext in PLpg/SQL
0 Summary (You can watch it last) Two structures contained in PLpgSQL_execstate: EState *simple_eval_estate, ExprContext *eval_econtext ExprContext is generally enough to be thrown to the SQL engine for execution, but ExprContext will rely on the EState structure to create it, so when PL is executed, the plpgsql_exec_function function needs to pass in the EState structure […]
