命名空间

查看所有namespace

bash 复制代码

USER>zn "%SYS"		# 切换到 %SYS namespace
%SYS>DO ##class(%SYS.Namespace).ListAll(.nslist)    # 调用namespace函数，将结果放到nslist变量
%SYS>ZW nslist     # 打印变量，输出namespace
nslist("%SYS")=""
nslist("DOCBOOK")=""
nslist("NS01")=""
nslist("SAMPLES")=""
nslist("TEST_NP1")=""
nslist("TSRC")=""
nslist("TVER")=""
nslist("USER")=""

切换命名空间

bash 复制代码

%SYS>zn "USER"		# 一定要带着双引号
USER>

数据库

获取到所有数据库路径

方案一：写个脚本查询

text 复制代码

<user>
<password>
ZN "%SYS"
SET rs = ##class(%ResultSet).%New("Config.Databases:List")
DO rs.Execute()
WHILE rs.Next() { WRITE rs.Get("Name"), ! }
DO rs.Close()
halt

查询：

bash 复制代码

[root@localhost tmp]# cat query_database.scr | csession TEST001
Node: localhost.localdomain, Instance: TEST001
Username: 
Password:

方案二：直接terminate查询

bash 复制代码

%SYS>DO rs.Execute()
%SYS>WHILE rs.Next() { WRITE rs.Get("Name"), ! }
