Question

Hello I am working on a SQL database

Using Microsoft SQL server 2008 R2
And Microsoft SQL Server management studio

I have a Database Called FixedNamesDb
On the database there is one table called All

It is similar to this (this is an example):

OldNames        NewNames
------------+---------------+
tom G         Thommas Grady               
Kate F        Kateline Farwell               
John S        Jhon Smith    

In another Database Called DescriptionDb There is lots of tables Table1, Table2, Table3 ….

Foreach Oldname in the FixedNamesDb I need to search all the tables in the DescriptionDb and if the oldname appears in any field i need to replace it with the newName

I search all the tables in DescriptionDb for a field containing “John S” and replace it with “Jhon Smith”

Any help on how to do this automaticaly? Usding a script, a query or something else.

More info:

• Each Name Appears only one time in one of the tables of DescriptionDb

• All the names appears (there is no name that does not exists)

• All the names are located in the Second Row of the table (Row where ID=2)

Thanks a lot for any help.

Use this script for each table that needs to be updated.

UPDATE
  DescriptionDb.Table1
SET
  Name = FN.NewName
SELECT
  FixedNamesDB.[All] AS FN
WHERE
  Name = FN.Oldname

The following script can find all tables and columns. Using a programming or scripting language loop through all tables and columns replacing Table1 and Name in the above script with all iterations of the script below.

SELECT
  TABLES.TABLE_SCHEMA + '.' + TABLES.TABLE_NAME 'TABLE_NAME',
  COLUMNS.COLUMN_NAME,
  COLUMNS.DATA_TYPE,
  COLUMNS.CHARACTER_MAXIMUM_LENGTH
FROM 
  INFORMATION_SCHEMA.COLUMNS,
  INFORMATION_SCHEMA.TABLES
WHERE
  COLUMNS.TABLE_NAME = TABLES.TABLE_NAME
  AND TABLES.TABLE_SCHEMA = 'DescriptionDb'
ORDER BY
  TABLES.TABLE_SCHEMA,
  TABLES.TABLE_NAME,
  COLUMNS.COLUMN_NAME
