– Create some test data
set nocount on
if object_id(‘[dbo].[srcTable]‘, N’U') is not null
drop table [dbo].[srcTable]
create table [dbo].[srcTable] (
[id] int not null primary key identity
, [name] nvarchar(50) not null
, [value] int not null
)
declare @counter int = 0
while (@counter < 1000)
begin
insert [dbo].[srcTable] ([name], [value]) select newid(), floor(rand() * 1000)
set @counter = 1 + @counter
end

if object_id('[dbo].[dstTable]', N'U') is not null
drop table [dbo].[dstTable]
create table [dbo].[dstTable] (
[id] int not null primary key –NO: identity
, [name] nvarchar(100) not null
, [value] decimal(18,2) not null
)
– This could be a stored proc parameter…
declare @tableName nvarchar(255) = '[dbo].[dstTable]'
– Separate the DROP and CREATE statements because sp_executesql can't handle batches.
declare @sql nvarchar(max) =
'if object_id(''[dbo].[targetView]'', N''V'') is not null
drop view [dbo].[targetView]'
exec sp_executesql @sql

set @sql =
'create view [dbo].[targetView] as
select id, name, value from '+@tableName
exec sp_executesql @sql
– Now do your conversions on the view…
set nocount off
insert [dbo].[targetView] (id, name, value)
select [id], [name], 33.3 * [value]
from [dbo].[srcTable]

select * from [dbo].[srcTable]
select * from [dbo].[dstTable]
select * from [dbo].[targetView]
/*
– Clean up
drop view [dbo].[targetView]
drop table [dbo].[dstTable]
drop table [dbo].[srcTable]
*/

So, while I can’t use @VARIABLE-TABLE-NAME directly, I know I can create an INSERT statement dynamically and EXECUTE it. The problem is passing in all the variables. Is there a way to do it within the query? Even if I created another external procedure, I’d be back to the same problem of making the tablename variable.
Thanks

declare @Column nvarchar(max) = ‘CombineConnectTime’
declare @Table nvarchar(max) = ‘Foo’
declare @Exists int

declare @SQLString nvarchar(max) = N’select @e=1 from sys.columns where name=@c and object_id=object_id(@t)’
declare @ParmDefinition nvarchar(max) = N’@e int output, @c nvarchar(max), @t nvarchar(max)’

– Test existance
create table dbo.Foo (
CombineConnectTime datetime
)
set @Exists = 0
execute sp_executesql @SQLString, @ParmDefinition, @e=@Exists output, @c=@Column, @t=@Table
if (@Exists = 1)
begin
print ‘Exists’
end
else
begin
print ‘Doesn”t exist’
end

– Test nonexistance
drop table dbo.Foo
set @Exists = 0
execute sp_executesql @SQLString, @ParmDefinition, @e=@Exists output, @c=@Column, @t=@Table
if (@Exists = 1)
begin
print ‘Exists’
end
else
begin
print ‘Doesn”t exist’
end

SET @Query = ‘SELECT * FROM sys.columns WHERE Name = ”CombineConnectTime” AND Object_ID = Object_ID(”’+@OurTableMirorName+”’)’

IF EXISTS(EXEC(@Query))
BEGIN
….
END

thanks

declare @vvSQL as varchar(max)
set @vvSQL = ‘select * from table_name’
select * from (exec (@vvSQL)) a, table_name_b b
where a.id = b.id

I want something similar to the above and do not want to create a temp table as the number of column would be different everytime.

Can You suggest some solution??

You’re concatenating a string with NULL and getting a NULL result. i.e.: @qry is NULL.

Instead of:
set @qry = ‘update ‘ + @str1 + ‘ set dob= ‘ + NULL + ‘ where dob like ”%XX/XX/%” or dob like ”%xx/xx/%”’;

You probably want:
set @qry = ‘update ‘ + @str1 + ‘ set dob=NULL where dob like ”%XX/XX/%” or dob like ”%xx/xx/%”’;

Also, unless your database is running with a case-sensitive collation, you could probably shorten it to this:
set @qry = ‘update ‘ + @str1 + ‘ set dob=NULL where dob like ”%XX/XX/%”’;

Good luck,

- I CAN ABLE TO EXECUTE ABOVE QUERY IF I CHANGED THE TABLE NAME ONE BY ONE…BUT I WANT TO MAKE POSSIBLE THIS QUERIES FOR 1 TO 100 TABLES WITHIN ONE SQL SYNTAX..
–========================================
DECLARE @intFlag INT;
declare @str1 nvarchar(100);
DECLARE @qry nvarchar(2000);
SET @intFlag = 5;
set @str1=”;
WHILE (@intFlag <=93)
BEGIN
PRINT @intFlag;
select @str1 = 'ac001part' + convert(nvarchar(10),CAST(REPLICATE(0,3-LEN(@intflag)) AS VARCHAR(3)) + CAST(@intflag AS VARCHAR(3)));
print @str1;

set @qry = 'update ' + @str1 + ' set dob= ' + NULL + ' where dob like ''%XX/XX/%'' or dob like ''%xx/xx/%''';
execute sp_executesql @qry ;
print @qry;
SET @intFlag = @intFlag + 1;
END
GO
–========================================
PLEASE HELP ME IMMEDIATELY AS SOON AS POSSIBLE…AS I SPOILED MY HALF OF THE DAY TO SOLVE THIS..ABOVE SQL SYNTAX IS CORRECT..NO ERROR..BUT IT'S OUTPUT NOT AFFECTS THE ROW…

if you’re right if I delete the use [] there is no problem, but actually want to do that view in all databases on the server, I have unprivileged SA but still does not work: (I try the solution ‘CREATE VIEW [Database ]. [dbo]. [vPersona_Relacion] sends me an error but”CREATE / ALTER VIEW can not specify the name of the database prefix the name of the object.’ll try the recommended solutions ‘OPENQUERY, OPENROWSET’ thanks for the help

good day

I have a better answer for this now. In Microsoft SQL land the create function/procedure/view statements are all limited to the current database – create table is the only exception and this is considered to be a hack for temp tables. Even using OPENROWSET is unable to work around this.

To create views in other databases you’re going to be stuck with two options: (1) create a .NET assembly that does the work for you using input parameters such as the remote database name and the create view SQL, or (2) use xp_cmdshell to launch and external process that does the same.

xp_cmdshell has security issues, and needs to be specifically enabled on the SQL server, but here is an example to do what you need…

use tempdb
go
declare @Database nvarchar(4000) = ‘TargetDatabase’
declare @SQL nvarchar(4000)
set @SQL = ‘CREATE VIEW [dbo].[vPersona_Relacion] as select [Foo]=1, [Bar]=2′
declare @Cmd nvarchar(4000)
set @Cmd =
‘sqlcmd.exe’
+’ -S(local) -E’ — Local server (may need an CLICONFG alias)
+’ -E’ — Trusted connection (SQL Service account in this case)
+’ -d”‘ + @Database + ‘”‘
+’ -Q”‘ + @SQL + ‘”‘ — Note: -Q exits, -q does not, use -Q
print @Cmd
exec xp_cmdshell @Cmd, no_output
go
select * from [TargetDatabase].[dbo].[vPersona_Relacion]
go
/*
use TargetDatabase
drop view [dbo].[vPersona_Relacion]
go
*/

Good luck,
AlwaysLearning

The error message says it all, “CREATE VIEW must be the first statement in a batch…” If you remove the “USE [database] GO” from the start of your statement it should work fine.

However, in this case, it looks as though you’re trying to create these views in other databases, which probably isn’t going to work (unless the currently executing user is SA-equivalent). Changing the create statement to ‘CREATE VIEW [Database].[dbo].[vPersona_Relacion]‘ may work. Otherwise, you may need to look into other solutions such as OPENQUERY, OPENROWSET or perhaps even a .NET Assembly.

Good luck,

There’s more to it than that. Specifically:

1. The Windows account that the SQL Server service is running under needs access to the remote server and share (and the file system the share provides access to). You can check which account this is via the Services snap-in (services.msc). By default it is the LOCAL SYSTEM user but more secure installations should have a least-privileged local user account instead.

2. Using (built-in) SQL Backup over a network connection is unreliable, at best. Far better to continue backing-up to your local file system followed by an XCOPY (or better, NCOPY, SCP, etc.) to copy or move the .BAK files when the backups have completed.

3. Test your backups occasionally by restoring them to an offline/staging server. You should be doing this anyway, but its even more important after moving your backup files across a network.
