书签

注解

为了使用书签功能,你需要配置 phpMyAdmin配置存储

存储书签

任何被执行的查询都可以在显示结果的页面上被标记为一个书签。你会发现一个标有 将此查询标记为书签 的按钮,就在页面的最后。一旦你存储了一个书签,该查询就被链接到数据库中。现在你可以在每个页面上访问一个书签下拉框,该数据库的查询框出现在该页面上。

在书签中使用变量

Inside a query, you can also add placeholders for variables. This is done by inserting into the query SQL comments between /* and */. The special string [VARIABLE{variable-number}] is used inside the comments. Be aware that the whole query minus the SQL comments must be valid by itself, otherwise you won’t be able to store it as a bookmark. Also, note that the text ‘VARIABLE’ is case-sensitive.

When you execute the bookmark, everything typed into the Variables input boxes on the query box page will replace the strings /*[VARIABLE{variable-number}]*/ in your stored query.

Also remember, that everything else inside the /*[VARIABLE{variable-number}]*/ string for your query will remain the way it is, but will be stripped of the /**/ chars. So you can use:

/*, [VARIABLE1] AS myname */

将展开为

, VARIABLE1 as myname

in your query, where VARIABLE1 is the string you entered in the Variable 1 input box.

现在举一个更复杂的例子。假如你保存了这个查询:

SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE1]%' */

假如你输入了“phpMyAdmin”作为变量,完整的查询将会是:

SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'

NOTE THE ABSENCE OF SPACES inside the /**/ construct. Any spaces inserted there will be later also inserted as spaces in your query and may lead to unexpected results especially when using the variable expansion inside of a “LIKE ‘’” expression.
