How can I get 300? Use reverse with charindex. Reverse is to put the string upside down, and then use charindex to obtain the first *

In SQL queries, if we want to output the queried result set as a string, for example, querying employees in the northwind database, the returned result is {address | birthdate | city | country | employeeid | extension | firstname | hiredate | homephone | lastname | notes | photo | photopath | postalcode | region | reportsto | title | titleofcourtesy |} format. We can do this. Declare @ columns nvarch

This method mainly describes how to remove data from the SQL Server database without using Dataset. Compared with the former, this method reduces the amount of code required for retrieval from the database.1. Contact code: 1: using System.Xml.Serialization; 2: 3: /// 4: /// Summary description for Contact 5: /// 6: /// 7: [XmlRoot("Contacts")] 8: public class Contact 9: { 10: public

For example: I want to convert string[] str = {"4", "5", "6"} to "' 4 ', ' 5 ', ' 6 '" string. So I can use SQL query: SELECT * from TableName ID in (string).The source code implemented in the project is as follows: StringBuffer idsstr = new StringBuffer (); for (int i = 0; i The other way I think of mys

Only SQL functions can be used to manipulate fields in a SELECT statement (linked to SQL Server).Select field 1 from Table 1 where field 1. IndexOf ("cloud") = 1;The reason this statement is not correct is that the indexof () function is not an SQL function, so it can be changed to the corresponding function of SQL.Left () is an

Sql-function Create function Database output results are separated by commas, and in development there are also many arguments passed in the form of comma-string arguments (not recommended when data is large). For example: Find the name "John, Li II" data in the database at this time to do this parameter processing as shown: The function code is as follows CREATE FUNCTION [dbo].[ FNSPLITSTR] (@s

variable length.Vi. How do I use these types?If you are sure of the length of the stored data and do not pack in Chinese, you can choose the char type. If you are sure of the stored data length, but may include Chinese, you can choose the nchar type. If you are unsure of the length of the stored data, store only English, the best use of the number varchar If you are unsure of the length of the stored data, it is possible to have Chinese, you can choose the nvarchar type, and in

Sometimes we split the strings when we use bulk operations, but there is no split function in SQL Server, so it's up to you to implement it yourself. There's nothing to say, just take it with your friends.
