Automatically Create Indexes in Different Filegroup, edit Publish Profile Script

Question

I need a way to automatically move clustered indexes into one filegroup : ClusteredFilegroup, and all nonclustered indexes to a different filegroup NonClusteredFilegroup upon DDL creation . We have sql publish profile which creates similar script below every weekly deployment. How do I utilize powershell to conduct this?

I would like to have powershell add words ON [ClusteredFilegroup] after every table creation

or ON [NonClusteredFilegroup] for every nonclustered index.

Powershell should be able to read original script (testscript.sql), and run text edits on it.

Original Script:

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);

Goal:

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];

I am trying to research these scripts:

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

This should do the trick:

$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) tells the replace statement to match multiple lines (m) and include new-lines (s) and ignore case (i). (.*?) includes anything including newlines (hence the (?smi)), but not greedy (?).

Yes, the line `$sql = Get-Content .\org.sql -Raw` reads a SQL file. Replace `.\org.sql` with a filename and/or path to your `.sql` file, for instance: `$sql = Get-Content d:\Exports\testscript.sql -Raw` This helped a lot: https://stackoverflow.com/a/12573413/1846184 And this: https://regex101.com/r/rkm4bT/1 And you may upvote the answer if you're happy with it. – Finzzownt Mar 15 '19 at 18:44
