Replace function in TEXT or NTEXT fields SQL Server We often use replace function in SQL server databases to find and replace a specific string. The SQL statement is straightforward and there is no any issue when we search and replace a string on a column with a datatype, not either TEXT or NTEXT. The general search and replace SQL statement is UPDATE tbl_name SET column_name = REPLACE(column_name, 'old_string', 'new_string') WHERE column_name like '%old_string%' The problem occurs when you try to search and replace a string on a column with datatype TEXT or NTEXT and the error message: Argument data type text is invalid for argument 1 of replace function. and SQL server do not have any recommendation on how to resolve, probably we know REPLACE function only work on varchar or nvarchar datatype The simplest way is converted TEXT or NTEXT data to NVARCHAR(MAX) and then use Replace function. Using below query you can replace string in TEXT or NTEXT data type column. UPDATE tbl_name SET column_name = CAST(REPLACE(CAST(column_name as nvarchar(MAX)),'old_string','new_string') AS NText) WHERE column_name LIKE '%old_string% This way you can replace strings in TEXT or NTEXT column.

Rewrite of counter by partition

AnotherOps

I use mysql and php with phpmyadmin. I have major problem with a partition based counter that I wan't to improve but my knowledge on sql prevents me from doing that. Im struggling very much with this.

I want the duplicated data in my table to have a counter that adds a number after a value if this value gets a duplicated value and then restarts from 1 until a new value is met and so on. Here is what the final result should look like

---------------------------
1  | Josh-1
---------------------------
2  | Josh-2
--------------------------
3  | Josh-3 
--------------------------
4  | Josh-4 
--------------------------
5  | Fred-1 
--------------------------
6  | Fred-2
--------------------------
7  | Fred-3
-------------------------

I had gotten help with this counter here before but it's not working as I wan't it to. Also when I have pressed the insert button in my form the table looks like this in phpmyadmin after I reload it

---------------------------
1  | Josh-1-1-1
---------------------------
2  | Josh-2
--------------------------
3  | Josh-3 
--------------------------
4  | Josh-4 
--------------------------
5  | Fred-1 
--------------------------
6  | Fred-2
--------------------------
7  | Fred
-------------------------

Whats going on here? The code that I seek help with rewriting is this

UPDATE usermeta u1,
(SELECT
u1.`id`, CONCAT(u1.`name`,'-',ROW_NUMBER() OVER(PARTITION BY u1.`name` ORDER BY u1.`id`)) newname
FROM 
usermeta u1 JOIN (SELECT `name` , COUNT(*) FROM usermeta GROUP BY `name` HAVING COUNT(*) > 1) u2
ON u1.`name` = u2.`name` ) u3
SET u1.`name` = u3.`newname`
WHERE u1.`id` = u3.`id`

Could this code be rewritten so it creates a table of numbered names and duplicates that looks like the first table example and work like it should in phpmyadmin ? All help is very much appreciated. Keep in mind that I am a struggling moderate sql user.
