look at some common data types in C. C #: Int intValue = 1; // same as JAVA. In C #, int is divided into int32, int16, and int64. Int64 is like long longValue = 2l; // It is the same as JAVA. Float floatValue = 1f; // same as JAVA. Double doubleValue = 2d; // same as JAVA. String stringValue = "aomi"; // C # contains two types of strings: string and String (note that the first letter is capitalized ). It is commonly written in the string type. String is the object type corresponding to string.

To a 8-bit barcode. Do not EAN-13, and do not UPCA examples of functions. Based on a given 8-digit number such as "71020034" to generate barcodes, do not need to check the code bit, the bar code will display a given 8 digits, scanning use.

PL/SQL. 　　 This is an example of creating a table. This process has two parameters: Table Name and field and its type list. 　　 Create or replace procedure ddlproc (tablename varchar2, cols varchar2) Cursor1 INTEGER; BEGIN Cursor1: = dbms_ SQL .open_cursor; Dbms_ SQL .parse (cursor1, 'create table' | tablename | '(' | cols | ')', dbms_ SQL .v7 ); Dbms_ SQL .close_cursor (cursor1 ); End; / 　　 2. How do I find the name of the primary key field of the database table? SQL

1. %: any string containing zero or multiple characters. In some cases, use two percentage signs for Chinese characters. For example: Where title like '% Computer %' searches for all titles of the word "computer" contained anywhere in the title. Select * from [user] Where u_name like '% 3%' indicates that u_name is "Zhang San", "Zhang Mao San", and "three-legged Cats ", "Tang sanzang" and so on have all records of "3. In addition, if you need to find records with "three" and "cat" in u_name, use

% Any string containing zero or more characters. Where title like '% Computer %' searches for all titles containing the word computer in any location of the title. _ (Underline) Any single character. Where au_fname like '_ EAN' searches for the names of all four letters ending with EAN (such as dean and Sean ). [] Specifies any single character in the range ([a-f])

Like Determines whether the specified string matches the specified pattern. The mode can contain regular and wildcard characters. During pattern matching, regular characters must match exactly the characters specified in the string. However, any part of a string can be used to match a wildcard. And use = and! = Compared to string comparison operators, using wildcards makes the like operator more flexible. If no parameter belongs to the string data type, Microsoft SQL Server converts it to the st
