Search a keyword in Sql2005/2008 in all tables


How to search all columns of all tables in a database for a keyword?

While browsing the SQL Server newsgroups, every once in a while, I see a request for a script that can search all the columns of all the tables in a given database for a specific keyword. I never took such posts seriously. But then recently, one of my network administrators was troubleshooting a problem with Microsoft Operations Manager (MOM). MOM uses SQL Server for storing all the computer, alert and performance related information. He narrowed the problem down to something specific, and needed a script that can search all the MOM tables for a specific string. I had no such script handy at that time, so we ended up searching manually.

That's when I really felt the need for such a script and came up with this stored procedure "SearchAllTables". It accepts a search string as input parameter, goes and searches all char, varchar, nchar, nvarchar columns of all tables (only user created tables. System tables are excluded), owned by all users in the current database. Feel free to extend this procedure to search other datatypes.

The output of this stored procedure contains two columns:

- 1) The table name and column name in which the search string was found
- 2) The actual content/value of the column (Only the first 3630 characters are displayed)

Here's a word of caution, before you go ahead and run this procedure. Though this procedure is quite quick on smaller databases, it could take hours to complete, on a large database with too many character columns and a huge number of rows. So, if you are trying to run it on a large database, be prepared to wait (I did use the locking hint NOLOCK to reduce any locking). It is efficient to use Full-Text search feature for free text searching, but it doesn't make sense for this type of ad-hoc requirements.

Create this procedure in the required database and here is how you run it:

--To search all columns of all tables in Pubs database for the keyword "Computer"
EXEC SearchAllTables 'Computer'
GO


Here is the complete stored procedure code:

CREATE PROC SearchAllTables
(
 @SearchStr nvarchar(100)
)
AS
BEGIN




 CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

 SET NOCOUNT ON

 DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
 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
    INSERT INTO #Results
    EXEC
    (
     'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) 
     FROM ' + @TableName + ' (NOLOCK) ' +
     ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
    )
   END
  END 
 END

 SELECT ColumnName, ColumnValue FROM #Results
END

Pagination and sorting dynamically in SQLserver 2005/2008


Hi this article show you how to do pagination and dynamically sorting the result ascending or descending from the selection list in sql 2005/2008

Create PROCEDURE [dbo].[usp_get_all_groups] 
    -- Add the parameters for the stored procedure here
    @pStartIndex smallint,
    @pPageSize tinyint,
    @pOrderBy varchar(15)
AS
BEGIN

 SELECT *
 FROM
  (SELECT ROW_NUMBER() OVER (ORDER BY 
      CASE WHEN @pOrderBy='GroupId ASC' THEN UserGroups._id END ASC,  
      CASE WHEN @pOrderBy='GroupId DESC' THEN UserGroups._id END DESC,             
      CASE WHEN @pOrderBy='GroupCode ASC' THEN UserGroups.GroupCode END ASC,
      CASE WHEN @pOrderBy='GroupCode DESC' THEN UserGroups.GroupCode END DESC) AS Row, 
      * FROM UserGroups) AS StudentsWithRowNumbers
  WHERE Row>= @pStartIndex AND Row <= @pStartIndex + @pPageSize
  ORDER BY Row      END
Here to execute the procedure 
DECLARE @return_value int
EXEC    @return_value = [dbo].[usp_get_all_groups]
        @pStartIndex = 0,
        @pPageSize = 15,
        @pOrderBy = N'GroupCode ASC'
SELECT  'Return Value' = @return_value
