Upgrading Your SQL Server: How to `Rebuild Full-Text Indexes` After Migration from 2000 to 2005

Upgrading an SQL Server database can often be fraught with pitfalls, especially when dealing with full-text catalogs. After migrating your database from SQL Server 2000 to SQL Server 2005, you may find that your full-text catalogs didn’t transfer as expected. If you’ve right-clicked and tried the “rebuild indexes” option only to find your system hanging without progress, you’re not alone and there’s a solution!

Understanding the Problem

Full-text search capabilities can be vital for many applications, allowing for efficient searching through large volumes of text data. Upon upgrading to SQL Server 2005, you might face the challenge where:

Full-text catalogs do not move seamlessly from one version to another.
Simply clicking “rebuild indexes” may result in prolonged inactivity or freezing.

This can hinder your database functionalities, so it’s essential to tackle this issue effectively.

Solutions: Rebuilding Full-Text Indexes

Instead of relying solely on GUI options, using SQL queries provides a more reliable route to rebuild your full-text catalogs on SQL Server 2005. Here’s how you can go about it:

Step 1: Use SQL Commands

You can execute SQL commands directly to create or alter your full-text catalogs. Microsoft provides specific functions that can be employed for this purpose.

Creating a New Full-Text Catalog: You can initiate a new catalog using:
```
CREATE FULLTEXT CATALOG YourCatalogName AS DEFAULT;
```
Altering an Existing Full-Text Catalog: To rebuild an existing catalog, run:
```
ALTER FULLTEXT CATALOG YourCatalogName REBUILD;
```

Note: Before executing the rebuild, ensure all the corresponding tables and indexed columns are fully populated.

Step 2: Check Accent Sensitivity

It’s also important to manage the accent sensitivity of your full-text catalog. Here’s a simple SQL command setup:

USE AdventureWorks;
GO
ALTER FULLTEXT CATALOG ftCatalog 
REBUILD WITH ACCENT_SENSITIVITY=OFF;
GO
SELECT FULLTEXTCATALOGPROPERTY('ftCatalog', 'accentsensitivity');
GO

Step 3: Verify the Rebuild Status

Once you initiate the rebuild, it’s crucial to verify that everything is working as expected. You can check if your commands are executing properly and the catalog is established correctly, following up with queries to return:

The current properties.
Any changes that have been made, especially around accent sensitivity.
