将Oracle查询转换为MySQL查询。 all_indexes

Question

I'm trying to convert Oracle query to MySQL query. 我正在尝试将Oracle查询转换为MySQL查询。

My Oracle query has this: 我的Oracle查询具有以下内容：

CREATE OR REPLACE PROCEDURE myProc() AS
    iname all_indexes.index_name%TYPE;
    oname all_indexes.owner%TYPE;
BEGIN
    // Do something
END;

How can I port this to mySQL, since mySQL doesn't have all_indexes public environment variable? 由于mySQL没有all_indexes公共环境变量，如何将其移植到mySQL？

Answer 1

Just use a varchar datatype 只需使用varchar数据类型

CREATE OR REPLACE PROCEDURE myProc()
BEGIN
  DECLARE iname varchar(50);
  DECLARE oname varchar(50);

    // Do something
END;

You can query an information_schema.statistics to obtain names od indexes 您可以查询information_schema.statistics以获得索引的名称

Select * 
From information_schema.statistics
