GBase8a 集群查看哪些自定义函数和存储过程

GBase 8a数据库集群,提供了元数据表 gbase.proc 查看存储过程的情况, 也可以用show的快捷方式查看名字等。

gbase.proc 表结构

其中请关注

字段含义
name
specific_name
存储过程名字
db库名
type类型
procedure是存储过程
function 是自定义函数
ROUTINE_DEFINITION定义的主体
param_list参数列表
returns返回类型
body主体

存储过程查询样例


gbase> select * from gbase.proc where db='testdb' and name='executeSQL'\G;
*************************** 1. row ***************************
                  db: testdb
                name: executeSQL
                type: PROCEDURE
       specific_name: executeSQL
            language: SQL
     sql_data_access: CONTAINS_SQL
    is_deterministic: NO
       security_type: DEFINER
          param_list:
 S_SQL_TMP VARCHAR(21000)

             returns:
                body: BEGIN
    set @sql = S_SQL_TMP;
  PREPARE s1 FROM @sql;
 EXECUTE s1;
 DEALLOCATE PREPARE s1;
END
             definer: root@%

自定义函数查询样例

gbase> select * from proc where db='testdb' and name='f_test'\G;
*************************** 1. row ***************************
                  db: testdb
                name: f_test

       specific_name: f_test
            language: SQL
     sql_data_access: CONTAINS_SQL
    is_deterministic: NO
       security_type: DEFINER
          param_list: inDate datetime
             returns: datetime
                body: begin
  return date_add(inDate, interval 1 day);
end
             definer: root@%
