如何從SQL Server獲取數據庫轉儲2005

Question

我有SQL Server 2005和我正在尋找一種方式，採取數據庫轉儲

集創建一個反映數據庫INSERT語句，提前

感謝...

Answer 1

有幾種方法可以做到這一點。其中之一是使用SMO。以下是PowerShell中的一個示例：

$ServerInstance = "MyServer\MyInstance" 
$MyBackupPath = "c:\temp\MyDump.sql" 

$tables = @(
    'table1', 
    'table2', 
    '...' 
    'lasttable' 
) 

$server = New-Object ('Microsoft.SqlServer.Management.Smo.Server') $ServerInstance 
$scripter = New-Object ('Microsoft.SqlServer.Management.Smo.Scripter') $server 

$scripter.Options.SchemaQualify = $false 
$scripter.Options.ScriptSchema = $false 
$scripter.Options.ScriptData = $true 
$scripter.Options.NoCommandTerminator = $true 
$scripter.Options.ToFileOnly = $true 
$scripter.Options.FileName = $MyBackupPath 
$ServerUrn=$server.Urn 

$UrnsToScript = New-Object Microsoft.SqlServer.Management.Smo.UrnCollection 

foreach ($t in $tables) 
{ 
    $Urn = "$ServerUrn/Database[@Name='" + $database + "']/Table[@Name='" + $t + "' and @Schema='dbo']" 
    $UrnsToScript.Add($Urn) 
} 

$scripter.EnumScript($UrnsToScript) 

Answer 2

我發現的最佳方式是通過此代碼！

Procedure: sp_generate_inserts (Build 22) 
     (Copyright © 2002 Narayana Vyas Kondreddi. All rights reserved.) 

Purpose: To generate INSERT statements from existing data. 
     These INSERTS can be executed to regenerate the data at some other location. 
     This procedure is also useful to create a database setup, where in you can 
     script your data along with your table definitions.

NOTE:  This procedure may not work with tables with too many columns. 
     Results can be unpredictable with huge text columns or SQL Server 2000's sql_variant data types 
     Whenever possible, Use @include_column_list parameter to ommit column list in the INSERT statement, for better results 
     IMPORTANT: This procedure is not tested with internation data (Extended characters or Unicode). If needed 
     you might want to convert the datatypes of character variables in this procedure to their respective unicode counterparts 
     like nchar and nvarchar 

     ALSO NOTE THAT THIS PROCEDURE IS NOT UPDATED TO WORK WITH NEW DATA TYPES INTRODUCED IN SQL SERVER 2005/YUKON 


Example 1: To generate INSERT statements for table 'titles': 

     EXEC sp_generate_inserts 'titles' 

Example 2: To ommit the column list in the INSERT statement: (Column list is included by default) 
     IMPORTANT: If you have too many columns, you are advised to ommit column list, as shown below, 
     to avoid erroneous results 

     EXEC sp_generate_inserts 'titles', @include_column_list = 0 

Example 3: To generate INSERT statements for 'titlesCopy' table from 'titles' table: 

     EXEC sp_generate_inserts 'titles', 'titlesCopy' 

Example 4: To generate INSERT statements for 'titles' table for only those titles 
     which contain the word 'Computer' in them: 
     NOTE: Do not complicate the FROM or WHERE clause here. It's assumed that you are good with T-SQL if you are using this parameter 

     EXEC sp_generate_inserts 'titles', @from = "from titles where title like '%Computer%'" 

Example 5: To specify that you want to include TIMESTAMP column's data as well in the INSERT statement: 
     (By default TIMESTAMP column's data is not scripted) 

     EXEC sp_generate_inserts 'titles', @include_timestamp = 1 

Example 6: To print the debug information: 

     EXEC sp_generate_inserts 'titles', @debug_mode = 1 

Example 7: If you are not the owner of the table, use @owner parameter to specify the owner name 
     To use this option, you must have SELECT permissions on that table 

     EXEC sp_generate_inserts Nickstable, @owner = 'Nick' 

Example 8: To generate INSERT statements for the rest of the columns excluding images 
     When using this otion, DO NOT set @include_column_list parameter to 0. 

     EXEC sp_generate_inserts imgtable, @ommit_images = 1 

Example 9: To generate INSERT statements excluding (ommiting) IDENTITY columns: 
     (By default IDENTITY columns are included in the INSERT statement) 

     EXEC sp_generate_inserts mytable, @ommit_identity = 1 

Example 10:  To generate INSERT statements for the TOP 10 rows in the table: 

     EXEC sp_generate_inserts mytable, @top = 10 

Example 11:  To generate INSERT statements with only those columns you want: 

     EXEC sp_generate_inserts titles, @cols_to_include = "'title','title_id','au_id'" 

Example 12:  To generate INSERT statements by omitting certain columns: 

     EXEC sp_generate_inserts titles, @cols_to_exclude = "'title','title_id','au_id'" 

Example 13: To avoid checking the foreign key constraints while loading data with INSERT statements: 

     EXEC sp_generate_inserts titles, @disable_constraints = 1 

Example 14:  To exclude computed columns from the INSERT statement: 
     EXEC sp_generate_inserts MyTable, @ommit_computed_cols = 1
