自动在其他文件组中创建索引,编辑发布配置文件脚本

我需要一种方法,可以在创建DDL时自动将聚簇索引移动到一个文件组:ClusteredFilegroup,并将所有非聚簇索引移动到另一个文件组NonClusteredFilegroup。我们有sql publish配置文件,它在每周的部署下面创建类似的脚本。我如何利用Powershell进行此操作?

我想让Powershell添加单词 每次创建表后ON [ClusteredFilegroup]

ON [NonClusteredFilegroup](针对每个非聚集索引)。

Powershell应该能够读取原始脚本(testscript.sql),并在其上运行文本编辑。

原始脚本:

GO
CREATE TABLE [dbo].[Dim_Product] (
    [DimProductId]        INT            IDENTITY (1, 1) NOT NULL,
    [ProductName]         VARCHAR(64)    NOT NULL,
    [ProductDescription]  VARCHAR(64)    NOT NULL,
    [BeginDate]           DATETIME       NOT NULL,
    [EndDate]             DATETIME       NOT NULL,
    CONSTRAINT [PK_DimProductId] PRIMARY KEY CLUSTERED ([DimProductId] ASC)
);

GO
CREATE NONCLUSTERED INDEX [NCX_Product_ProductName]
    ON [dbo].[Dim_Product]([ProductName] ASC);

GO
CREATE NONCLUSTERED INDEX [NCX_Product_BeginDate]
    ON [dbo].[Dim_Product]([BeginDate] ASC);   


GO
CREATE TABLE [dbo].[Dim_Customer] (
    [DimCustomertId]        INT           IDENTITY (1, 1) NOT NULL,
    [CustomerName]         VARCHAR(64)    NOT NULL,
    [CustomerDescription]  VARCHAR(64)    NOT NULL,
    [BeginDate]           DATETIME        NOT NULL,
    [EndDate]             DATETIME        NOT NULL,
    CONSTRAINT [PK_DimCustomerId] PRIMARY KEY CLUSTERED ([DimCustomerId] ASC)
);

GO
CREATE NONCLUSTERED INDEX [NCX_Customer_CustomerName]
    ON [dbo].[Dim_Customer]([CustomerName] ASC);

GO
CREATE NONCLUSTERED INDEX [NCX_Customer_BeginDate]
    ON [dbo].[Dim_Customer]([BeginDate] ASC);

目标:

CREATE TABLE [dbo].[Dim_Product] (
     [DimProductId]        INT           IDENTITY (1, 1) NOT NULL,
     [ProductName]         VARCHAR(64)   NOT NULL,
     [ProductDescription]  VARCHAR(64)   NOT NULL,
     [BeginDate]           DATETIME      NOT NULL,
     [EndDate]             DATETIME      NOT NULL,
     CONSTRAINT [PK_DimProductId] PRIMARY KEY CLUSTERED ([DimProductId] ASC)
    ) ON [ClusteredFilegroup];

    GO
CREATE NONCLUSTERED INDEX [NCX_Product_ProductName]
     ON [dbo].[Dim_Product]([ProductName] ASC) ON [NonClusteredFilegroup];

我正在尝试研究以下脚本:

Add text to every line in text file using PowerShell

Search a text file for specific word if found copy the entire line to new file in powershell

这应该可以解决问题:

$sql = Get-Content .\org.sql -Raw
$sql = $sql -replace '(?smi)(CREATE TABLE (.*?))\);','$1 ) ON [ClusteredFilegroup];'
$sql = $sql -replace '(?smi)(CREATE NONCLUSTERED INDEX (.*?))\);','$1) ON [NonClusteredFilegroup];'
$sql | Set-Content -Path .\new.sql

(?smi)告诉replace语句匹配多行(m),包括换行(s),并忽略大小写(i)。 (.*?)包括换行符(因此(?smi)),但不包括贪婪(?)。
