1. 工作环境需求

A. The operating system user >sid

B. The R/3 table DBCON must be maintained.

C. The correct database library 'dboraslib.>ext<' must exist in the kernel directory.
Connect to SQL Server database Prerequisite: At least one Windows application server must be available on the R/3 system and the DBSL dynamic library (DLL) dbmssslib.dll must be installed on this server. This dll can be downloaded from the SAP Service Marketplace.

dbmssslib.dll

2. 配置连接信息

配置TCODE: dbco

任何配置信息都存储在DBCON表中.

配置示例:

A. 访问MSSQL的配置示例(参见SAP Notes 178949)

CON_NAME: >my_conn_name<
DBMS: MSS
USER_NAME: >db_user<
PASSWORD: >password<
CON_ENV: MSSQL_SERVER=>server_name< MSSQL_DBNAME=>db_name<

db_user could be sapr3 for example if the server is running R/3. The password field may be blocked from view by asterisks in sm30. USER_NAME can be left blank in order to use integrated security (4.6d kernel and later). In that case make sure that the OS User running R/3 has the required privilege on the remote server. A dummy password must be entered in sm30, it will not be used when the user name is blank.

B. 访问ORACLE的配置示例()

Connection name logical name of the connection

DBMS ORA

User name Oracle users

DB password password for the above-mentioned Oracle user

Conn.info TNS alias

Permanent Usually should not be set for a secondary connection.

3. 程序中如何使用

report zdbcon .
data: dbn(128).
EXEC SQL.
CONNECT TO 'DAN1'
ENDEXEC.
EXEC SQL.
SET CONNECTION 'DAN1'
ENDEXEC.
EXEC SQL.
SELECT db_name() INTO :DBN FROM SVERS
ENDEXEC.
write: / 'current database name', dbn.
DAN1在DBCON表中配置
CON NAME DAN1
DBMS MSS
USER NAME iis_log
PASSWORD CON ENV
MSSQL_SERVER=tcp:###.###.###.### MSSQL_DBNAME=iislog
