Label: Today I find that it is not too long to read a blog post, as long as you can describe what you want to express, to let people know what you want to say. Because I read some long blog today, I really feel that there are too many knowledge points, it will make people swallowed. This blog post is similar to the one I published yesterday to address a statistical requirement, and the result is a request to return the month from which the definition input was extrapolated from the c

Redesign the table when we often encounter such a situation, the value of the field is 1,2,3,4 and other characters separated, the existence of a number, but the display is the corresponding category, direct, clear,How to get it done in two steps, as follows:The first step is to create a table-valued function that turns 1,2,3,4 intoThe function is found from the Internet, the code is as follows:Create FUNCTION [dbo]. [Fn_split] (@String nvarchar (max)

New table-valued Function:Create function [dbo]. [F_split] (@SourceSql varchar (8000), @StrSeprate varchar (Ten)) Returns @temp table (a varchar ( -)) asBEGIN DECLARE @iint Set@SourceSql =RTrim (LTrim (@SourceSql))Set@i=charindex (@StrSeprate, @SourceSql) while@i>=1begin insert @temp values (left (@SourceSql, @i-1)) Set@SourceSql =substring (@SourceSql, @i+1, Len (@SourceSql)-@i)Set@i=charindex (@StrSeprate, @SourceSql) Endif@SourceSql '\ 'I

The regular expression is very good, but it is not in the database, but it can be extended by way of an assemblyWrite a DLL first, scalar functions well written, table-valued functions a little troubleHere is the C # code using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server; using System.Text.RegularExpressions; using System.Collections; public partial class

executed. Of course, there is a way, is to spell SQL, each loop a data, first of all, if not repeat, I write a SQL statement saved in a variable, until the loop to the last bar, you may spell a number of INSERT statements, and finally sent to the database once Yes, but have you ever thought that once the amount of data is too large, tens of thousands of, or hundreds of thousands of pieces of data to spell the string can imagine how long, sent to the database will be truncated. Not to mention st

Differences between SQL table valued functions and scalar functions When writing SQL stored procedures, you often need to call some functions to make the processing process more reasonable and make the function more reusable. However, you may find that when writing SQL functions, some functions are written under the table value function and some are written under the scalar value. The difference is that the table value function can only retu

The main idea: to give you a 1 2 3 sequence, you can sort, to exchange any two elements at a time, ask the minimum number of exchangesIdea: Greedy, first row 1, if 1 is already in position, then do not move, if it is 2 that and the front of the 1 exchange, if 3, then and the back of the 1 exchange1 /*{2 id:a42984423 Prob:sort34 lang:c++5 }6 */7#include 8#include 9 #defineMAXN 5000Ten using namespacestd; OneIfstream Fin ("sort3.in"); AOfstream Fout ("Sort3.out"); - //#define FIN CIN - //#define F

We can know the result after the last sort, that is, the position of all the third-place;So we can pre-count the number of three-way, and then for the 2,3 in the 1 position we first respectively to their respective positions, to find whether there are 1 and then exchange, if not to find another location, after processing 1, we will be 2 of the position of the number of 3, we can get the answer.The code is as follows:/*id:15674811lang:c++task:sort3*/#include #include #include #include using names

Label: Similar to the past, I still introduce a daily development encountered in the knowledge points, I would like to record, but also hope to help some friends. This time I'm going to go through the SQL function to return the date data that you entered in the two points in time. As follows: Execute function: SELECT * FROM [Fn_runselectday] (' 2015-01-01 ', ' 2015-01-11 ') The specific functions are as follows: -- =============================================--Call: SELE

As always, a short blog post records a problem encountered during the development process. The original intention is to record some of their own idea, but also want to be able to help some coincidence encounter such a problem, the need for the beginning is because, to count the last n weeks of sales data. Let's take a look at the effect of the execution function, such as SELECT * FROM [dbo]. [Fn_runweek] (-12) The specific functions are as follows: -- ===============================
