MS SQL Server实用工具说明(bcp/tabdiff)

 

Sql得Dts.dll没有注册

注册方式如下：点击开始--输入CMD运行后，在命令窗口粘贴：cd C:\Program Files\Microsoft SQL Server\90\DTS\Binn\     （注意路径是自己安装SQL2005的目录）

然后到如上的安装目录了，再粘贴：

regsvr32.exe C:\Program Files\Microsoft SQL Server\90\DTS\Binn\dts.dll

（注意本应是如上地址，但因cmd中不允许路径有空格会报错，因此如下处理可避免）

subst w: "C:\Program Files\Microsoft SQL Server\100\DTS\Binn"

（输入后回车，此步是做路径转换，定义“W:\”盘符，以代替有空格的路径）

regsvr32.exe w:\dts.dll     （注册dts.dll，注册成功！终于可以导入数据了）

Returns the list of supported parameters.

-sourceserver source_server_name[\instance_name]

Is the name of the source server. Specify source_server_name for the default instance of SQL Server. Specify source_server_name\instance_name for a named instance of SQL Server.

-sourcedatabase source_database

Is the name of the source database.

-sourcetable source_table_name

Is the name of the source table being checked.

-sourceschema source_schema_name

The schema owner of the source table. By default, the table owner is assumed to be dbo.

-sourcepassword source_password

Is the password for the login used to connect to the source server using SQL Server Authentication.

Security Note: 

When possible, supply security credentials at runtime. If you must store credentials in a script file, you should secure the file to prevent unauthorized access.

 

-sourceuser source_login

Is the login used to connect to the source server using SQL Server Authentication. If source_login is not supplied, then Windows Authentication is used when connecting to the source server. When possible, use Windows Authentication.

-sourcelocked

The source table is locked during the comparison using the TABLOCK and HOLDLOCK table hints.

-destinationserver destination_server_name[\instance_name]

Is the name of the destination server. Specify destination_server_name for the default instance of SQL Server. Specify destination_server_name\instance_name for a named instance of SQL Server.

-destinationdatabase subscription_database

Is the name of the destination database.

-destinationtable destination_table

Is the name of the destination table.

-destinationschema destination_schema_name

The schema owner of the destination table. By default, the table owner is assumed to be dbo.

-destinationpassword destination_password

Is the password for the login used to connect to the destination server using SQL Server Authentication.

Security Note: 

When possible, supply security credentials at runtime. If you must store credentials in a script file, you should secure the file to prevent unauthorized access.

 

-destinationuser destination_login

Is the login used to connect to the destination server using SQL Server Authentication. If destination_login is not supplied, then Windows Authentication is used when connecting to the server. When possible, use Windows Authentication.

-destinationlocked

The destination table is locked during the comparison using the TABLOCK and HOLDLOCK table hints.

-b large_object_bytes

Is the number of bytes to compare for large object data type columns, which includes: text, ntext, image, varchar(max), nvarchar(max) and varbinary(max). large_object_bytes defaults to the size of the column. Any data above large_object_bytes will not be compared.

-bf number_of_statements

Is the number of Transact-SQL statements to write to the current Transact-SQL script file when the -f option is used. When the number of Transact-SQL statements exceeds number_of_statements, a new Transact-SQL script file is created.

-c

Compare column-level differences.

-dt

Drop the result table specified by table_name, if the table already exists.

-et table_name

Specifies the name of the result table to create. If this table already exists, -DT must be used or the operation will fail.

-f [ file_name ]

Generates a Transact-SQL script to bring the table at the destination server into convergence with the table at the source server. You can optionally specify a name and path for the generated Transact-SQL script file. If file_name is not specified, the Transact-SQL
script file is generated in the directory where the utility runs.

-o output_file_name

Is the full name and path of the output file.

-q

Perform a fast comparison by only comparing row counts and schema.

-rc number_of_retries

Number of times that the utility retries a failed operation.

-ri retry_interval

Interval, in seconds, to wait between retries.

-strict

Source and destination schema are strictly compared.

-t connection_timeouts

Sets the connection timeout period, in seconds, for connections to the source server and destination server.
