Option 1: Start with a new and empty database.
Option 2: Restore the SonarQube database and change the database collation using SQL Management Studio (assuming that the database is called SonarQube) before starting the upgrade again:
-- Show current collation
USE [master]
GO
SELECT [collation_name]
FROM [sys].[databases]
WHERE name = 'SonarQube'
GO
The result should be Latin1_General_CS_AS. If the query returns SQL_Latin1_General_CP1_CS_AS change the database collation before upgrading to 6.0:
USE [master]
GO
ALTER DATABASE [SonarQube] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
ALTER DATABASE [SonarQube] COLLATE Latin1_General_CS_AS;
ALTER DATABASE [SonarQube] SET MULTI_USER
GO
Option 3: (last resort) Change the database collation (see option 2) and change the database manually (using SQL Management Studio). First execute the following query
USE [SonarQube]
GO
SELECT '[' + SCHEMA_NAME(t.[schema_id]) + '].[' + t.[name] + '] -> ' + c.[name]
, 'ALTER TABLE [' + SCHEMA_NAME(t.[schema_id]) + '].[' + t.[name] + ']
ALTER COLUMN [' + c.[name] + '] ' + UPPER(tt.name) +
CASE WHEN t.name NOT IN ('ntext', 'text')
THEN '(' +
CASE
WHEN tt.name IN ('nchar', 'nvarchar') AND c.max_length != -1
THEN CAST(c.max_length / 2 AS VARCHAR(10))
WHEN tt.name IN ('char', 'varchar') AND c.max_length != -1
THEN CAST(c.max_length AS VARCHAR(10))
WHEN tt.name IN ('nchar', 'nvarchar', 'char', 'varchar') AND c.max_length = -1
THEN 'MAX'
ELSE CAST(c.max_length AS VARCHAR(10))
END + ')'
ELSE ''
END + ' COLLATE Latin1_General_CS_AS' +
CASE WHEN c.[is_nullable] = 1
THEN ' NULL'
ELSE ' NOT NULL'
END
FROM [sys].[columns] c
JOIN [sys].[tables] t ON c.[object_id] = t.[object_id]
JOIN [sys].[types] tt ON c.[system_type_id] = tt.[system_type_id] AND c.[user_type_id] = tt.[user_type_id]
WHERE c.[collation_name] IS NOT NULL
AND c.[collation_name] != 'Latin1_General_CS_AS'
AND t.[type] = 'U'
GO
This will return several lines; for example:
ALTER TABLE [dbo].[resource_index]
ALTER COLUMN [root_component_uuid] NVARCHAR(50) COLLATE Latin1_General_CS_AS NOT NULL
Some columns cannot be changed in this way because the column is used in an index that must be dropped first. For example:
-- Pay attention: generate script first!
DROP INDEX [resource_index_component] ON [dbo].[resource_index]
GO
ALTER TABLE [dbo].[resource_index]
ALTER COLUMN [component_uuid] NVARCHAR(50) COLLATE Latin1_General_CS_AS NOT NULL
GO
-- Generate the create script in SQL Management Studio...
CREATE NONCLUSTERED INDEX [resource_index_component]
ON [dbo].[resource_index] ([component_uuid] ASC)
WITH (...) ON ...
GO
Restart SonarQube and start the upgrade again.
