Select all from all tables all columns

I sometimes need to search for something that I know I added in one of the tables in a database, but i just don't know where I added it.
So for this one, I would need something to search in all the tables.
This case, only 'char', 'varchar', 'nchar', 'nvarchar' columns.

I searched on the internet, and found this guy.
The stored procedure is pretty cool, it works just the way I wanted.
I only added a SOUNDEX to it, so it can find even if you misspell the word.

it takes a while (around 10 seconds on a 400 tables database), but it is very cool.

I am thinking about how nice would it be to implement a search like this in your application (linking to the right screen, that might need a lot of parameters is probably the hard part)

So here's the code:

CREATE PROC ADMNSP_HotSearch
(
@SearchStr NVARCHAR(100)
)
AS
BEGIN
CREATE TABLE #Results (ColumnName NVARCHAR(370), ColumnValue NVARCHAR(3630), Accuracy INT)

SET NOCOUNT ON

DECLARE @TableName NVARCHAR(256), @ColumnName NVARCHAR(128), @SearchStr2 NVARCHAR(110), @mySQL VARCHAR(8000)
SET @TableName = ''
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

WHILE @TableName IS NOT NULL
BEGIN
SET @ColumnName = ''
SET @TableName =
(
SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
AND OBJECTPROPERTY(
OBJECT_ID(
QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
), 'IsMSShipped'
) = 0
)

WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)
BEGIN
SET @ColumnName =
(
SELECT MIN(QUOTENAME(COLUMN_NAME))
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = PARSENAME(@TableName, 2)
AND TABLE_NAME = PARSENAME(@TableName, 1)
AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar')
AND QUOTENAME(COLUMN_NAME) > @ColumnName
)

IF @ColumnName IS NOT NULL
BEGIN
SET @mySQL = 'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) , 1
FROM ' + @TableName + ' (NOLOCK) ' +
' WHERE SOUNDEX(' + @ColumnName + ') = SOUNDEX(''' + @SearchStr + ''') AND ABS( LEN(' + @ColumnName + ') - LEN(''' + @SearchStr + ''') ) < 10 '

/*PRINT (@mySQL)*/

INSERT INTO #Results
EXEC (@mySQL)
END
END
END

UPDATE #Results SET Accuracy = 0 WHERE CHARINDEX(@SearchStr, ColumnValue) > 0

SELECT DISTINCT ColumnName, ColumnValue, Accuracy, CHARINDEX(@SearchStr, ColumnValue) AS [CHARINDEX] FROM #Results Order by Accuracy, ColumnValue
DROP TABLE #Results
END

Float vs. Decimal

I used float instead of decimal, I'll never do that again.
I found some stored procedures, that had numeric parameters used as varchar. I'll never do that either.
Check out why:

1st case:

declare @a as float
set @a = 13705.05
select @a

declare @b as varchar(100)
set @b = @a
select @b

2nd case:

declare @a as float
set @a = 137.86
select @a

declare @b as varchar(100)
set @b = @a
select @b

Run them, You'll get this:
1st case:

13705.05
13705

2nd case:

137.86
137.86

see my point?
