Iterate Through and Rename All Tables w/ Object Qualifiers MSSQL - sql

Question

I need to iterate through all of the tables that begin with a specific prefix to rename them. The code I've tried is below, but it ends with one of two results, either it crashes SSMS (sometimes), or I get the error message below for each table. I've tried with and with out dbo.
Can anyone tell me what I'm doing wrong or perhaps suggest a better way to do this?
No item by the name of 'dbo.prefix_TableName' could be found in the current database 'DatabaseName', given that #itemtype was input as '(null)'.
Here's the code I'm running...
SET NOCOUNT ON;
USE [DatabaseName];
DECLARE #oq NVARCHAR(5), #tableName NVARCHAR(128), #newTableName NVARCHAR(128);
SET #oq = N'prefix_';
/*
find and rename all tables
*/
DECLARE [tableCursor] CURSOR FOR
SELECT [TABLE_NAME] FROM INFORMATION_SCHEMA.TABLES
WHERE [TABLE_TYPE] = 'BASE TABLE' AND [TABLE_NAME] LIKE #oq + '%'
ORDER BY [TABLE_NAME];
OPEN [tableCursor]
FETCH NEXT FROM [tableCursor] INTO #tableName
WHILE ##FETCH_STATUS = 0
BEGIN
SET #newTableName = REPLACE(#tableName, #oq, N'');
EXEC('EXEC sp_rename ''dbo.' + #tableName + ''', ''' + #newTableName + '''');
END
CLOSE [tableCursor];
DEALLOCATE [tableCursor];

A simpler solution without cursors
declare #oq nvarchar(max) = N'prefix_'
declare #cmd nvarchar(max)
select #cmd = a from (
select 'EXEC sp_rename ''' + TABLE_NAME + ''', ''' + REPLACE(TABLE_NAME, #oq, N'') + ''' '
from INFORMATION_SCHEMA.TABLES
for xml path('')
) t(a)
exec sp_executesql #cmd
In your example nvarchar(5) causes truncation, you probably need nvarchar(7) or nvarchar(max).
