Nice script.
A couple of questions for you:
- Shouldn't there be a set of [ ] around the variables in case they contain special characters like blanks or SQL keywords?
- How can you handle special characters in the LIKE comparison if a string you would search for has a %, _, [ ], [^ ] or quotes?

I agree. It failed immediately for me for a column named "Group".
SET @Sql = 'SELECT @Row_Count = COUNT(*) '+
' FROM ' + @Table_Name + ' (NOLOCK) WHERE [' + @Column_Name + '] LIKE ''%' + @Search_For + '%'''
Adding the brackets prevents the ambiguity of the word.
Given that, I see this as a useful time-saver when a word or phrase may have been used in numerous places.
Thanks!

Fair point. I'll have to make the change. The times that I used it I wasn't looking for anything with special characters or keywords.

I've now added the []'s around the table_name and column_name. I'm not sure when the update will be posted but its a fairly simple change.
Change this line
' FROM ' + @Table_Name + ' (NOLOCK) WHERE ' + @Column_Name + ' LIKE ''%' + @Search_For + '%'''
To this line
' FROM [' + @Table_Name + '] (NOLOCK) WHERE [' + @Column_Name + '] LIKE ''%' + @Search_For + '%'''
As far as pattern searching goes if you want to search on a pattern matching character put it in []'s. So for example if you want to search for the literal string 'test%' you would put it as 'test[%]'.
I thought about putting it in code but then you couldn't add extra patterns. For example as it stands you can search on the word 'test' with a single digit number after it by making the search string 'test[0-9]'

I admit my SQL knowledge is extremely limited, but am I missing something very basic here? All I get is an Error 208 - Invalid Object Name INFORMATION_SCHEMA.Tables. It would appear that these views only exist in and relate to the master database on our system. All of our other databases, setup by applications such as a Sage ERP system, Backup Exec, etc., have no such views.
February 12, 2008 at 8:04 am
They are system views. They do only exist in Master but everyone should have access to them and they can be used from any database. Just like the system stored procedures. I'm honestly not sure why you can't use them normally. If you want I can re-write it to work on the base system tables.

Actually the answer was quite simple: quite why I am not sure, but on our system all these objects are defined with upper case names and have to be referenced as such, e.g. "INNER JOIN INFORMATION_SCHEMA.TABLES Tables ON Columns.TABLE_NAME = Tables.TABLE_NAME". Many Thanks.

Actually I'll bet you have your default collation set to be case sensative. On all of the systems I have run it on the server has been case in-sesative so I didn't have any problems.
Hope you find the script helpful 🙂

How do you see the results?. When I execute the script I get a bunch of '(1 row(s) affected'. Thanks for your assistance.
May 18, 2012 at 2:27 pm
If you are using "results to text" the output will be between the 3rd and 4th "(1 row(s) affected)" .
I'm adding a SET NOCOUNT ON to the top of the script in order to turn off the extra output.
You probably arn't getting any results. If you switch to "results to grid" you will get your results seperate from the text output.

Thank you. Very useful and simple.

Thanks for the script.

I know it's been years since this post was made and the script still works great.
I just added the TABLE_SCHEMA to make thing run a bit better on my db that has many different schema's. No other changes was made.
SET NOCOUNT ON
DECLARE @Search_For varchar(4000)
DECLARE @Table_Name varchar(255)
DECLARE @Schema_Name varchar(255)
DECLARE @Column_Name varchar(255)
DECLARE @Row_Count int
DECLARE @Sql nvarchar(4000)
DECLARE @Results Table
(
Table_Name varchar(255),
Column_Name varchar(255),
Row_Count int
)
DECLARE Field_List CURSOR FOR
SELECT COLUMNS.Table_Name, COLUMNS.TABLE_SCHEMA, COLUMNS.Column_Name
FROM INFORMATION_SCHEMA.COLUMNS COLUMNS
INNER JOIN INFORMATION_SCHEMA.TABLES TABLES ON COLUMNS.Table_Name = TABLES.Table_Name
WHERE COLUMNS.Data_Type IN ('char','varchar','nchar','nvarchar','text','ntext')
AND TABLES.Table_Type = 'Base Table'
----------------------------------
SET @Search_For = '051021.upd'
----------------------------------
OPEN Field_List
FETCH NEXT FROM Field_List INTO @Table_Name, @Schema_Name, @Column_Name
WHILE (@@fetch_status <> -1)
BEGIN
IF (@@fetch_status <> -2)
BEGIN
-- Generate & run dynamic SQL
SET @Sql = 'SELECT @Row_Count = COUNT(*) '+
' FROM [' + @Schema_Name + '].[' + @Table_Name + '] (NOLOCK) WHERE [' + @Column_Name + '] LIKE ''%' + @Search_For + '%'''
EXEC sp_ExecuteSql @Sql, N'@Row_Count Int OUTPUT', @Row_Count OUTPUT
IF @@Error <> 0
PRINT @Sql
-- Store results
IF @Row_Count > 0
INSERT INTO @Results VALUES (@Table_Name, @Column_Name, @Row_Count)
END
FETCH NEXT FROM Field_List INTO @Table_Name, @Schema_Name, @Column_Name
END
CLOSE Field_List
DEALLOCATE Field_List
SELECT * FROM @Results
GO
