The result of a general division operation is that a column is derived from the table that is being removed, and the remainder from the relationship table. Here is an example to illustrate. Let's say there are three tables: Customer customers, sales employees, order orders, queries return some customers an
There is no division operation in the T-SQL, but in the T-SQL you can implement a division-like Operation divide. Generally, the result of the division operation is a column from the partitioned relational table, and the rest from the partitioned relational table. Here is an example. Assume that there are three tables as follows: Customer MERs, sales personnel employees, order orders. The query returns some customers and requires these customers and all U.S. employees to have at least one tra
publisher. Click the Query window and enter the following statement:
SELECT phone from authors WHERE au_name= "Ringer"
When the input is complete, click the Execute Query button (a green triangle that looks like a VCR playback key). When you click this button, any statements that appear in the query window are executed. The query window automatically becomes the result display window, and you can see the results of the query (see Figure 10.3).

specifically designed the JSON data type, retrieval of this type, and other function parsing. Let's take a look at JSON access in earlier MySQL versions.
Example Table Structure:
CREATE TABLE json_test(id INT,person_desc TEXT)ENGINE INNODB;
Insert a record:
INSERT INTO json_test VALUES (1,'{ "programmers": [{ "firstName": "Brett", "lastName": "McLaughlin", "email": "aaaa" }, { "firstName": "Jason", "lastName": "Hunter", "email": "bbbb" }, {

complex data type in JSON is array. The JSON array uses the array literal form in JavaScript. ExampleFor example, the following is the array literal in JavaScript:Var values = [25, "hi", true];In JSON, the same syntax can be used to represent the same array:[25, "hi", true]Likewise, JSON arrays do not contain variables or semicolons. Combining arrays with objects can form more complex data sets,For example:[{"Title": "Professional JavaScript ","Authors
