SQLServer 使用ADSI执行分布式查询ActiveDorectory对象

复制代码 代码如下:

-- Query for a list of User entries in an OU using the SQL query dialect
select convert(varchar(50), [Name]) as FullName,
convert(varchar(50), Title) as Title,
convert(varchar(50), TelephoneNumber) as PhoneNumber
from openquery(ADSI,
'select Name, Title, TelephoneNumber
from ''LDAP://OU=Directors,OU=Atlanta,OU=Intellinet,DC=vizability,DC=intellinet,DC=com''
where objectClass = ''User''')
-- Query for a list of Group entries in an OU using the SQL query dialect
select convert(varchar(50), [Name]) as GroupName,
convert(varchar(50), [Description]) GroupDescription
from openquery(ADSI,
'select Name, Description
from ''LDAP://OU=VizAbility Groups,DC=vizability,DC=intellinet,DC=com''
where objectClass = ''Group''')

复制代码 代码如下:

CREATE TABLE #tmpADUsers
( employeeId varchar(10) NULL,
SAMAccountName varchar(255) NOT NULL,
email varchar(255) NULL)
GO
/**//* AD is limited to send 1000 records in one batch. In an ADO interface you can define this batch size, not in OPENQUERY.
Because of this limitation, we just loop through the alphabet.
*/
DECLARE @cmdstr varchar(255)
DECLARE @nAsciiValue smallint
DECLARE @sChar char(1)
SELECT @nAsciiValue = 65
WHILE @nAsciiValue < 91
BEGIN
SELECT @sChar= CHAR(@nAsciiValue)
EXEC master..xp_sprintf @cmdstr OUTPUT, 'SELECT employeeId, SAMAccountName, Mail FROM OPENQUERY( ADSI, ''SELECT Mail, SAMAccountName, employeeID FROM ''''LDAP://dc=central,dc=mydomain,dc=int''''WHERE objectCategory = ''''Person'''' AND SAMAccountName = ''''%s*'''''' )', @sChar
INSERT #tmpADUsers
EXEC( @cmdstr )
SELECT @nAsciiValue = @nAsciiValue + 1
END
DROP TABLE #tmpADUsers
