1、procedure-name: 存储过程的名字,在同一个数据库的同一模式下,不能存在存储过程名相同参数数目相同的存储过程,即使参数的类型不同也不行。 2、(IN | OUT | INOUT parameter-name data-type,…) :传入参数 IN:输入参数 OUT:输出参数 INOUT:作为输入输出参数 parameter-name:参数名字,在此
在此期间,显然需要一种新的语言来与新的系统进行交互。Codd 写了一篇新论文“一种基于关系演算的数据库子语言”,它成为了称为 DSL/Alpha 的新语言的基础。这很快经历了一些名称的变化,但最终被称为 SQL,结构化查询语言的缩写。 最终,在 20 世纪 70 年代,有人尝试将 DSL/Alpha 移植到 370 大型机环境中。它...
The rapid, efficient cloning processes support multiple use case for production-like replicas without production impact, such as: Creating or refreshing of robust, life-like quality assurance (QA) or test environments Moving a workload to another environment, such as query environments Separating ...
Multiple values can be specified for the IP address and port conditions, either directly in the condition or as a referenced group. IPv6 addresses are fully supported. When creating TTLSRules, you should avoid defining rules of the same kind that overlap. Example 10 shows two overlapping rules...
1 For a static MERGE statement, if FOR n ROWS is not specified, values-multiple-row is treated as values-single-row. For a dynamic MERGE statement, FOR n ROWS does not need to be specified in the MERGE statement. It can be specified in the EXECUTE statement, but cannot be specified in...
ThePATCH2keyword specifies a workaround for known problems with ODBC applications. To set multiplePATCH2values, list the values sequentially, separated by commas. For example, if you want patches 300, 301, and 302, specifyPATCH2= "300,301,302" in the initialization file. The valid values for...
VALUES (value1, value2...);具体示例如下。 INSERT INTO employees.employees (emp_no, birth_date, first_name, last_name, gender, hire_date) VALUES ('111111', '1976-11- 11', 'Gary', 'Chen', 'M', '1998-08-20'); MySQL支持用一条INSERT语句插入多条记录,这样可以加快数据的导入,比如下面...
()example, this plugin is meant as an example for application developers to write their own plugins if the functionality of JITDB is not enough. JITDB is good for indexing specific values, likementions(alice.id)which gets its own dedidated JITDB index foralice.id. But when querying ...
If a parameters file is used, then each line specifies the parameter values for a given statement and a given iteration of a block. If instead #PARAM directives are used, multiple values and even parameter ranges are specified in advance for each parameter of each statement, and on each ...
