Search Through entire database for a value
Query for searching the entire database for a string value
To run this query in your own senerio, just change the 'Cal' to any string you desire

Kill Active Processes for a particular SQL Database
Below is a SQL script that I use all the time when it comes down to hung procedures and any unwanted processes that are left open. This below T-SQL could also be turned into a procedure quite easily and used as a cleanup job before running any backups.
DECLARE @p_SPID int, @p_SQL nvarchar(2000), @dbName nvarchar(100) -- Change the 'Database Name' to the database that you intend to kill the processes for SET @dbName = 'Database Name' DECLARE #cur_Processes CURSOR FOR SELECT p.SPID FROM master.dbo.sysprocesses AS p JOIN master.dbo.sysdatabases AS d ON( d.dbid = p.dbid ) WHERE d.Name = @dbName AND p.SPID > 50 -- AND spid >= 51 (because spids of 50 or less are reserved for internal use.) OPEN #cur_Processes FETCH NEXT FROM #cur_Processes INTO @p_SPID WHILE @@FETCH_STATUS = 0 BEGIN SET @p_SQL = 'KILL ' + CONVERT( nvarchar(30), @p_SPID ) PRINT @p_SQL EXECUTE( @p_SQL ) FETCH NEXT FROM #cur_Processes INTO @p_SPID END CLOSE #cur_Processes DEALLOCATE #cur_Processes
Sql Object Schema
So inorder to Find a table schema in sql you have two options
-- this will show all tables within this database SP_TABLES -- this is a more selective search select * from INFORMATION_SCHEMA.tables WHERE TABLE_NAME =
this can also be done with columns
-- this will show all column definations within the table specfied SP_Columns -- this is a more selective search on one or many views at one time select * from INFORMATION_SCHEMA.columns WHERE TABLE_NAME =
using OPENROWSET to import excel files into Sql tables
As I am currently looking into ways in which I could automate dataloading from multiple file formats using stored procedures. I stumbled accross OPENROWSET, which proves to have more than what i bargined for with being able to support multple file types which include (access, Excel, csv, text)
So for this post I am looking into the Excel data loading. I know what you are all thinking, that there are many more better ways out there to load data into a sql table than using OPENROWSET, but I am Limited to using Sql server 2000 and creating a stored procdure like below allows the importer to have more flexibility that if i was to say use a DTP package or other build in import/export functions.
So below is a script for a stored procedure that helps handle the OPENROWSET function. With only 3 parameters to specify, inorder to load an excel file/sheet into a sql table.
create procedure sp_ImportExcelFile
(@Source varchar(1000)
, @SourceSheet varchar (100)
, @DestinationTable varchar (100))
as
declare @retval int
EXEC master..xp_fileexist @Source, @retval output -- check if file exists
if @retval = 0
begin
print 'file does not exist.'
return
end
-- sets default sheet name to Sheet1 if not specfied
if @SourceSheet is null or @SourceSheet = ''
set @SourceSheet = '[Sheet1$]'
else
set @SourceSheet = '[' + ltrim(rtrim(@SourceSheet)) + '$]'
if @DestinationTable is null or @DestinationTable = ''
set @DestinationTable = substring(@SourceSheet, 2, len(@SourceSheet) - 3) + convert(varchar, getdate(), 126)
exec('select * into [' + @DestinationTable + '] from openrowset(''Microsoft.Jet.OLEDB.4.0'', ''Excel 8.0;HDR=YES;Database=' + @Source + ''', ' + @SourceSheet + ')')
