SQLCMD -- Part III (Non-Interactive or batch Mode)

If you haven't gone through the first two posts about SQLCMD I would strongly recommend to go over it here and here before proceeding further :)

1. Executing a script file from SQLCMD...

i. Create a script file by typing in the following line and save it as Message.sql
print 'Welcome today''s date is: ' + (convert(varchar, getdate()))

ii. Now goto command prompt and type: SQLCMD -i Message.sql
here, -i is the switch to specify the input file name.


2. Executing series of script files (sample)

Lets create couple of .sql files and then see how to execute them in order from command prompt. Please note that i am just showing an example here :) there are better methods of doing the same which I would explain later in the series!

i) Copy paste the below script and name it as 01TableCreation.sql

Create table tblTest
(
Sno int identity,
FName varchar(20)
)
Go

ii) Copy paste the below script and name it as 02InsertRecords.sql
Insert into tblTest (Fname) values ('a')

iii) Copy paste the below two lines and name it as test.bat

sqlcmd -U sa -P hotmail -S VADIVEL -d testbed -i "C:\Vadivel\SQL
Related\Scripts\sqlcmd\01TableCreation.sql"
sqlcmd -U sa -P hotmail -S VADIVEL -d testbed -i "C:\Vadivel\SQL
Related\Scripts\sqlcmd\02InsertRecords.sql"

here,
-U is SQL User name
-P is SQL Password
-S is the SQL Server name
-d is the SQL database name
-i is the input file to execute

iv) Execute the batch file

Now goto command prompt (Start >> Run >> cmd) and execute this batch file. The batch file would have created a table and inserted a record into it. If you want to deploy some DB scripts on a remote box for which you don't have access from Mgmt Studio you can follow this batch file route. So that the ppl who are having access to that SQL box can just run this batch file (after changing the values of the different switches, if need be)

Registry manipulation from SQL

Registry Manupulation from SQL Server is pretty easy. There are 4 extended stored procedure in SQL Server 2000 for the purpose of manupulating the server registry. They are: 1) xp_regwrite 2) xp_regread 3) xp_regdeletekey 4) xp_regdeletevalue Let us see each one of them in detail! About xp_regwrite This extended stored procedure helps us to create data item in the (server’s) registry and we could also create a new key. Usage: We must specify the root key with the @rootkey parameter and an individual key with the @key parameter. Please note that if the key doesn’t exist (without any warnnig) it would be created in the registry. The @value_name parameter designates the data item and the @type the type of the data item. Valid data item types include REG_SZ and REG_DWORD . The last parameter is the @value parameter, which assigns a value to the data item. Let us now see an example which would add a new key called " TestKey ", and a new data item under it called TestKeyValue :

Screen scraping using XmlHttp and Vbscript ...

I wrote a small program for screen scraping any sites using XmlHttp object and VBScript. I know I haven't done any rocket science :) still I thought of sharing the code with you all. XmlHttp -- E x tensible M arkup L anguage H ypertext T ransfer P rotocol An advantage is that - the XmlHttp object queries the server and retrieve the latest information without reloading the page. Source code: < html > < head > < script language ="vbscript"> Dim objXmlHttp Set objXmlHttp = CreateObject("Msxml2.XMLHttp") Function ScreenScrapping() URL == "UR site URL comes here" objXmlHttp.Open "POST", url, False objXmlHttp.onreadystatechange = getref("HandleStateChange") objXmlHttp.Send End Function Function HandleStateChange() If (ObjXmlHttp.readyState = 4) Then msgbox "Screenscrapping completed .." divShowContent.innerHtml = objXmlHttp.responseText End If End Function </ script > < head > < body > &l

Script table as - ALTER TO is greyed out - SQL SERVER

One of my office colleague recently asked me why we are not able to generate ALTER Table script from SSMS. If we right click on the table and choose "Script Table As"  ALTER To option would be disabled or Greyed out. Is it a bug? No it isn't a bug. ALTER To is there to be used for generating modified script of Stored Procedure, Functions, Views, Triggers etc., and NOT for Tables. For generating ALTER Table script there is an work around. Right click on the table, choose "Modify" and enter into the design mode. Make what ever changes you want to make and WITHOUT saving it right click anywhere on the top half of the window (above Column properties) and choose "Generate Change Script". Please be advised that SQL Server would drop actually create a new table with modifications, move the data from the old table into it and then drop the old table. Sounds simple but assume you have a very large table for which you want to do this! Then it woul
