Hi all,
I know that if I access the syscolumns table I can select all the column names in the table.
example: select name from syscolumns
NOw what I need to know is how to do a describe on these tables. For example in oracle if I type in (desc syscolumns) it would give me the structure of the table itself. The other thing I need to know is how to get the columns names for a specific table. I do not want all the column names but only for a specific table in that database.
Any thoughts will be greatly appreciated.

Which field in syscolumns can tell you if that field can accept null vaules or not in 7.0 there is a column call "isnullable" that store this information?
i have a database where in the syscolumns table.... each record entry for a INDENTITY field in any table the field syscolumns.PRINTFMT has binary / char trash in it... has anyone ever ran in to this and can this be a big problem ?
Hi, I have run a DBCC CHECKDB and it found 2 Errors in syscolumns. I have run a CHECKTABLE and found the following Error:
Server: Msg 8928, Level 16, State 1, Line 1 Object ID 3, index ID 2: Page (1:266) could not be processed. See other errors for details. Server: Msg 8944, Level 16, State 1, Line 1 Table Corrupt: Object ID 3, index ID 2, page (1:266), row 12. Test (VarColOffsets + (int)(sizeof (class VarColOffset) * nVarCols) <= (nextRec - pRec)) failed. Values are 178 and 72. DBCC results for 'syscolumns'. There are 6963 rows in 144 pages for object 'syscolumns'. CHECKTABLE found 0 allocation errors and 2 consistency errors in table 'syscolumns' (object ID 3). repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKTABLE (EMIS.dbo.syscolumns ).
Can anyone suggest the best way to proceed with this problem. I am a little dubious about running REPAIR_ALLOW_DATALOSS on syscolumns, I am unsure of what will happen if sections of syscolumns go missing. I have run DBCC PAGE ('EMIS',1,266,1) but this has given me nothing to work with.
All my online research has told me how to get info about a table field's data using the system tables, but I can't find anything that tells how to get that table field's data specifically. Could be that it's difficult to explain so difficult to search on but I know there has to be a way to do this and it can't be that difficult.
How do I use the system tables sysobjects and syscolumns to give me the data from a specific field in a third table?
Basically I don't want to know the field type for a tables field, I want to know that field's value.
Let's say I have a table called tblCompanies and that table has 4 fields. idCompany, companyName, companyState, and companyCountry.
How can I return the value as a command parameter for any one of the 4 fields using sysobjects and syscolumns?
If I were writing dynamic SQL I would do something like this:
set @valueToReturn = exec ('select ' + @fieldNameToReturn + ' from ' + @tableToSearch + ' where ' + @fieldToMatchOn + ' = ' + @valueToMatchOn)
But I don't want to use dynamic SQL, I want to use the existing system tables to write a straightforward query. My nonfunctioning/English version of this would be:
give me the value for the field name I send in as a string (@fieldNameToReturn) from the table I send in as a string (@tblToSearch) where (sysobjects.name = @tblToSearch) and (syscolumns.name = @fieldNameToReturn) and (@tblToSearch.@fieldnameToMatchOn = @valueToMatchAgainst)
I'm using sysobjects and syscolumns because that's where I can use my variables for table name and column name to link. I just can't figure out how to get hold of my actual data table and the values in it.
Does that make any sense to anyone? I'm sure someone has had to want something like this.
I ran the following query in Query Analyzer for a 7 column table.SELECT c.name,c.colid FROM syscolumns c WHERE c.id=925962375 ORDER BYc.colidThe results were:I_CSD 1X_STE_XML2I_USR_LCK4T_CRT_RCD5I_USR_CRT_RCD6T_UDT_RCD7I_USR_UDT_RCD8If I use the information_schema view (SELECT column_name,ordinal_position FROM information_schema.columns WHERE table_name ='CSD_XML') I get the same results.The problem is that the colids go from 2 to 4 and the colids gothrough 8 when there are only 7 columns.At one time there was another column in the table, but it has sincebeen dropped and isn't there anymore. It seems that the colids insyscolumns did not update when the column was dropped.Is this because of the way I dropped the column? Is there anything Ican do now that it has happened?

Hello, I am facing a huge problem in my sql server database using access as a front end.The main problem is trying to execute queries "views" ,since they reside on sql server now,and using variables or parameters in reports and forms to filter on this query. Ex. how can the following be implemented using the same query but in sql server? Access ------ SELECT MAT_Charts.YYYYMM FROM MAT_Charts WHERE ((([Area_Code] & "-" & [GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key])) GROUP BY MAT_Charts.YYYYMM;
It is specifically this statement in which I am interested: [GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key]))

Hi Guys i write a thread before asking for help with reading an uploaded csv file, i have my code, it reads the csv file and currently displays it in a datagrid but what i actually want is to take the read information and import it into my sql express db.

Hi, I am trying to make a backup of my database using Sql-DMO
When I do the backup on my server, my code runs fine. But when I backup from across the network from another computer, the database is saved on the server and not on the computer from where I am executing my application. How set SQLl-DMO to backup on the computer from where I am?
here is my code (found on the net)... Any suggestions greatly appreciated!
Cursor = Cursors.WaitCursor 'create an instance of a server class Dim my_srv As SQLDMO._SQLServer = New SQLDMO.SQLServerClass 'connect to the server my_srv.Connect("servername", "userid", "password")

I've a bactch file that is ran by the user and it looks for files and if it doesnot exist it waits for it and when it exsits, through isql it truncates the table and bcp in the file. In bcp files the loginname used in isql has dbo rights to truncate the table and the batch file also has password. The user who runs the script can also view the batch file and can know the password, Is there any way I could rewrite it so that the user cann't view the password or other way like SQL DMO or DTS package

According to our stratergy we are taking trans log backup of every user database everuy two hours.things seem to work great and with success at the day time and at night once at 12.03 and 2.03 they fail and when i checked the error log i found that there is only one database for which its failing and it gives the following error.
Database ors: Transaction Log Backup... Destination: [D:BackupTranLogorsors_tlog_200108280203.TRN] [Microsoft SQL-DMO (ODBC SQLState: 42000)] Error 4213: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot allow BACKUP LOG because file 'ors_Data' has been subjected to nonlogged updates and cannot be rolled forward.

We had a option called select into/bulccopy set which i disabled once this failure has occured but still the problem persists....there are no other options set...i am out of resources i donno what to do..could you suggest me something and how to solve this problem its happening in prod.
As Said by someone i took a full backup...tooooo it does not solve the issue.
Need to write a storedprocedure to find the disk space of the server and disk space used on the server,there are devices created for the backup on these guide lines i need to check the is the disk space used is more than cetain % say 75% than find out which device occupies the maximum space out of all and reintialize it so as to free up the space.
We need to then schedule this every night so that it checks the space.
