Alter table valued parameter table type
I've found a [blog on sqltreeo.com](http://www.sqltreeo.com/wp/scripting-dependecies-of-user-defined-table-types/) which has a way to automate the process by temporary dropping the dependencies and then re-creating them. I just added a minor comment to show where to add your new table type and wrapped it in a transaction.
1.You should create the following procedure:
-- Find all referencing objects to user-defined table type in @fullObjectName parameter
-- and generate DROP scripts and CREATE scripts for them
CREATE PROC [dbo].[alterTableType] (@fullObjectName VARCHAR(200))
AS
BEGIN
SET NOCOUNT ON
IF (TYPE_ID (@fullObjectName) IS NULL)
BEGIN
RAISERROR ('User-defined table type ''%s'' does not exists. Include full object name with schema.', 16,1, @fullObjectName)
RETURN
END;
WITH sources
AS
(
SELECT ROW_NUMBER() OVER (ORDER BY OBJECT_NAME(m.object_id)) RowId, definition
FROM sys.sql_expression_dependencies d
JOIN sys.sql_modules m ON m.object_id = d.referencing_id
JOIN sys.objects o ON o.object_id = m.object_id
WHERE referenced_id = TYPE_ID(@fullObjectName)
)
SELECT 'BEGIN TRANSACTION'
UNION ALL
SELECT
'DROP ' +
CASE OBJECTPROPERTY(referencing_id, 'IsProcedure')
WHEN 1 THEN 'PROC '
ELSE
CASE
WHEN OBJECTPROPERTY(referencing_id, 'IsScalarFunction') = 1 OR OBJECTPROPERTY(referencing_id, 'IsTableFunction') = 1 OR OBJECTPROPERTY(referencing_id, 'IsInlineFunction') = 1 THEN 'FUNCTION '
ELSE ''
END
END
+ SCHEMA_NAME(o.schema_id) + '.' +
+ OBJECT_NAME(m.object_id)
FROM sys.sql_expression_dependencies d
JOIN sys.sql_modules m ON m.object_id = d.referencing_id
JOIN sys.objects o ON o.object_id = m.object_id
WHERE referenced_id = TYPE_ID(@fullObjectName)
UNION ALL
SELECT 'GO'
UNION ALL
SELECT CHAR(13) + CHAR(10) + '---- WRITE HERE SCRIPT TO DROP OLD USER DEFINED TABLE TYPE AND CREATE A NEW ONE ----' + CHAR(13) + CHAR(10)
UNION ALL
SELECT
CASE
WHEN number = RowId THEN DEFINITION
ELSE 'GO'
END
FROM sources s
JOIN (SELECT DISTINCT number FROM master.dbo.spt_values) n ON n.number BETWEEN RowId AND RowId+1
UNION ALL
SELECT 'COMMIT'
END
2.Then you should run it with your table type name as a input parameter. Show the results on grid format (because text format might truncate long texts), select entire result table and copy it to a new query window.
