I'd like to get information about tables defined in the SqlCe20 database. So I tried to use the following which doesn't work:
string sql = "SELECT COLUMN_NAME AS CN FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = ?"cmd = new SqlCeCommand(sql, connection);cmd.Parameters.Add(newSqlCeDataParameter("A", DbTypes.NVarChar);cmd.Prepare();//later in codecmd.Parameters[0].Value = tableName;reader = cmd.ExecuteReader();while (reader.Read())....
Here the reader.Read() returns always false indepent of the table name.
In contrast doing the following without parameter works as expected:
reader = cmd.ExecuteReader(string.Format("SELECT COLUMN_NAME AS CN FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = '{0}'", tableName));
while (reader.Read())
Because I have to execute this statemen often I have to use prepared statement with parameters.
We have a legacy app where some of our web page urls were hardcoded into the stored procs (SQL 2000 SP4 database). We have changed the system and so changed the hardcoded strings with a value stored in a config table. We used the following query to identify the hardcoded urls (say LegacyPage.asp) €“
select routine_name from information_schema.routines where routine_definition like '%LegacyPage.asp?%'
However, even after this we keep getting issues with LegacyPage.asp being referenced. Tracing the code, I found that there is at least one SP (say spHardCoded) which does not turn up in the query, but does have the string LegacyPage.asp? in the routine definition. When I run the following query €“
select routine_name from information_schema.routines where routine_name = 'spHardCoded' and routine_definition like '%LegacyPage.asp?%'
0 rows are returned!
Am I missing something obvious here or is INFORMATION_SCHEMA.Routines metadata not always updated? Is there any way to force the metadata to be updated, before we query it? Is there a better system catalog view which lets me do the same thing? Any help would be really appreciated.
When the procedure : sp_tables is executed (master db), the table owners are either dbo or INFORMATION_SCHEMA, any detail about this last ? (to be precise, table_type is view and not table).
I need to change a column default to '' and not null for 1500 databases accross 10 servers.
if exists (select * from information_schema.columns where table_name = 'tblABC' and column_name = 'columnX' and data_type = 'VARCHAR' and is_nullable = 'No' and column_default = '('')' ) begin --do something to implement end
Here, there is a problem for and column_default = '('')' I have tried ''''+'('')' + '''' or "'('')'", neither works. Do you have any idea to deal with the ('') ?
I'm having a really hard time displaying the structure of my database using INFORMATION_SCHEMA. Can this be used with Access? I've used it before for sql databases but when I try it with this access one I get an error message telling me: Can't find file c:...INFORMATION_SCHEMA.mdb
I'm hoping maybe there's another command that works just as well or some other way to get around it.
I'm using Visual Web Developer 2005 Express and my .aspx pages are coded using VB so any insights would be awesome!
Hi I need to see all the indexes in a database. The ID has dbo rightsto the database, but not to the master. I can't see anything inINFORMATION_SCHEMA.CHECK_CONSTRAINTS orINFORMATION_SCHEMA.KEY_COLUMN_USAGEAn sa ID for the master sees everything however.Thanks for your helpPachydermitis
Hiya, I'm trying to run reports, some of which have UserEntered as a criteria. So I'm filling up a list with (SELECT * FROM SysUsers WHERE IsLogin = 1), which is also pulling up INFORMATION_SCHEMA as a login. I'm not really sure why this would be an islogin = 1 or issqluser = 1. Is this a server default login,and if yes,why, and what can I do about it?
from SQL2005 information_schema, I don't see anything related to default constraint.
So, I still need the old way to use old stuff such as from sysobjects sobj inner join syscolumns scolumn. I need to check existing 3000 databases to drop any possible default for tableA.columnB's default and then add a new one.
I thought SQL2005 will stop let us to query system table to retrieve table structure info including default, but only via information_schema? :rolleyes: thanks David
I am new to SQLSERVER, so I am trying to learn from all these database views, in Oracle it use 'desc all_tables ' to database dictionary view, can some one tell me how to view SQLserver dictionary view like INFORMATION_SCHEMA.TABLES, or sys.tables?
IF I login as sa, but I only want to view the table list one schema at a time? how do I do that?
I tried :
select table_name from INFORMATION_SCHEMA.TABLES where table_schema='CIT'....
select table_name from INFORMATION_SCHEMA.TABLES where table_schema='CIT.DBO'.... give 0 result too.
it give me 0 result, but if I login as CIT, then
'select table_name from INFORMATION_SCHEMA.TABLES' will give 14 tables.
Plus, When I log into Query analyzer, all the tables has dbo. prefix. , why is that?
how do i return only the tables created by the user? in three of my databases i am inserting one record per 5 secs. in all the tables. how good is using triggers for 'insert instead of' for these tables?
Hi, I'm working with MSSQL2K+SP3a, Standard Edition. I defined linked server (MSDE). On the local server, I can do select * from [testDB].[INFORMATION_SCHEMA].[TABLES] -- local
select * from [testSRV].[testDB_far].[dbo].[sysobjects] -- linked
but not
select * from [testSRV].[testDB_far].[INFORMATION_SCHEMA].[TABLES]
How can I access the INFORMATION_SCHEMA on the linked server ?
I have a "master" table that holds the names of data tables (one record in the "master" table for each "data" table).
Can I create a ForeignKey constraint that will prevent the "master" table records from being removed if the cooresponding "data" table exists? Is the way to do this to use INFORMATION_SCHEMA.TABLES as the PrimaryKeyTable for the ForeignKey?
Hi Folks:I'm a little new to SQLServer, so please pardon my ignorance!I've found the INFORMATION_SCHEMA views for TABLES, COLUMNS, andTABLE_CONSTRAINTS. I'm looking for the views that will give me the list ofcolumns by constraint.For instance, if Table1 has a unique key called Table1_UK01, I can find thatunder INFORMATION_SCHEMA.TABLE_CONSTRAINTS. But I also need to know thecolumns in that UK constraint. I've triedINFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE andINFORMATION_SCHEMA.KEY_COLUMN_USAGE, but the UK I have defined for this usertable doesn't seem to show up in either of those views.Can anyone point me in the right direction? Any sample queries would betremendously appreciated. I'm going to be using this meta-data toautomatically generate quite a bundle of stored procs that do updates basedon finding rows via unique keys...TIA,Dave
Hi I'm building a data warehouse - my end users connect using Access via ODBC Microsoft SQL Server driver (2000.85.1117.00).
However, whenever they connect using Access via ODBC they get a huge list of sys and INFORMATION_SCHEMA views, in addition to the data warehouse tables they need to access.
How can I remove these sys and INFORMATION_SCHEMA views from the list of tables/views presented to the end user?
I've tried denying access by changing permissions to deny in the public role of the master database - I have also changed permissions in the public role in the data warehouse database. When I do this, the ODBC connection fails to retrieve any objects because it doesn't have access to sys.databases (and various other unspecified objects). I'm stuck - help!
we've just installed SQL2005 and, as expected, are hitting problems with collation settings.
We have made sure that the collation of our new server is the same as the old (working) SQL2000 server (both are Latin1_General_CI_AS) but a function that works fine on the 2000 box just doesn't work on the 2005 box.
The problem is this...
Code Snippet select * from information_schema.[tables] as t left join :: fn_ListExtendedProperty('MS_Description','user','dbo','table',null,null,null) as xp on ( xp.objname = t.table_name )
...where that string comparison on "table_name" results in...
"Cannot resolve the collation conflict between "Latin1_General_CI_AS" and "Latin1_General_CI_AI" in the equal to operation."
Now... I can't see where the "Latin1_General_CI_AI" is coming from. The two data sources are both "system" sources, so should, I would have thought, been the same. If I do...
execute sp_help "information_schema.tables"
...all the columns are Latin1_General_CI_AS. If I do...
execute sp_help fn_ListExtendedProperty
...the same collation is returned for all columns.
I've checked everything I can think of (server, master, tempdb, etc.), and everything seems to be "AS".
Where might this "AI" collation be defined ? We have only just installed 2005, so a re-install, while a pain, is not a massive problem, but what should we check/change ?
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?
I'm a newbie to SQL and wanted to see if someone could help me write a query. I store historical options data in a SQL data base and I'm trying to create a query that will retrieve all ATM (at the money options).
For each unique stock symbol (STOCK_SYMBOL) in my database find the strike price (STRIKE) which is closest to the stock price (UND_LAST). This will be refined by the EXPIRATION and OPT_TYPE
The following query returns all options not just ATM options.
SELECT STOCK_SYMBOL, UND_LAST, STRIKE, EXPIRATION FROM DATA
WHERE EXPIRATION > '2007-02-01 00:00:00' AND EXPIRATION < '2007-02-28 00:00:00' AND OPT_TYPE = 'CALL'
I am using MS SQL Server 2005 Import and Export Wizard (.net framework Data Provider for mySAP Business Suite. )
as a interface between SAP and MS SQL 2005.
Once the connection is created i can use basic query to fetch the data from SAP tables ie., SELECT * FROM AFPO
But say I want to EXTRACT data just for month of July from AFPO.
AFPO does not have date field so you have to join AFPO to AUFK and AUFK to COEP to fetch the date as a criteria to restrict data for the month of July .
This can be done in ABAP by view or Interim Table, if you have Developer Key.
Can anyone please tell me if aforesaid is possible with MS SQL Server 2005 Import and Export Wizard query ?
Hello, I want to find all the entries where the date field is a specific date; so I may have 5 entries with the date 1/1/2006, and I want to find all of those. However, datetime fields in SQL Server also have the time, so how do you handle that? Can you just say where requestdate = getdate() to get all of the entries that have records for today? How does time affect this?
Hi,I am new to sql and was wondering if someone could help with this select statement. please don't laugh!

Thanks!
Hey, What is the best way to query two datetime values to see if they are alike? I need to determine if an [AccountEndDate] is today (both values are datetime). Using "Like" does not work. Thanks!
If you create a view such as CREATE VIEW TestView AS Select * FROM customers_table WHERE CustomerID between 213 AND 3443 Each time you want to select from the view - is the View going to perform the WHERE clause on the customers_table, or not? Or does the view already have the virtual rows?, meaning it does not have to perform a where clause (WHERE CustomerID between 213 AND 3443) on the customers_table, and just performs an inner join with the rows it already has?
I have a usage table Aaccessdate (datetime)useridpageidI need to write a sql that would do a report on a monthly basis. ( how many pagehits per month)All is fine - and my SQL looks likes thisselect count(pageid)from A.The twist here is , I do not want to count those records if the same user visits the page on the same day.For Eg02/03/2005 10:09:09.000 user1 page102/03/2005 15:09:09.000 user1 page102/03/2005 11:09:09.000 user2 page202/03/2005 16:09:09.000 user3 page3I want my count to give me back 3 instead of 4.Can this be done?ThanksRajini
I have a table containing prices. This table will be queried very often to provide quotes for clients.So to ease the burden on the server I want to cache the table and then just query the cached version.However it seems that I can only cache the table as a datatable. This means I have to query the datatable to get the prices for each quote.I'm not sure how to query a datatable. Is ther syntax similar to querying a SQL table?In fact is this best way to go about things?Any help would be appreciated.G
im struggling to see what im doing wrong with the following SQL, wondering if it has something to do with the subquery being a view...cant think why though
select value from table where type = 'Extra Mailbox' and active = 1 and value not in (select login from view) order value
The view returns a list of logins and the type field is also a list of logins. I want to filter the list of logins that do not appear in the subquery....
I have 2 different database's on the same server. I'm trying to create a stored proc that resides in Reporting database but queries against the Call database. 4 part naming convention gives me an error of 'invalid object name' What am I forgetting here?
I have a table (tbl_a) with 2 columns: itemNames | Date . ItemNames can have duplicates. I have another table (tbl_b) with date ranges in 2 columns: startDate | endDate.
what I would like to do is: query tbl_a where date between startDate and endDate of tbl_b.
Both of these columns contain npanxx numbers which would be the first 6 digits of a phone number, example 217345 which is in illinois.
Table B Columns:
npanxx, state
table B hold all npanxx numbers in the united states and what state it pertains to.
what i need to do is run a query to check and see what state the OriginatingNumber and the TerminatingNumber are in and decide if both numbers passed are in the same state or not.
so for example in Table A Row 1: OriginatingNumber is 217345 and the TerminatingNumber is 309454. I need to check both of these numbers against table B and it would return that both numbers are in IL. Basically I need to return a result of yes or no. yes they are in the same state or no they are not in the same state.
I have 2 tables Staff and Class which are as follows
Staff ID (Primary Key) FirstName MiddleName Surname Etc. . .
Class ID (Primary key) LessonTemplateID TeacherID TermID AssistantID
LessonTemplateID and TermID link to other tables which i don't need right now.
The Class.TeacherID and Class.AssistantID both link to the Staff.ID
I am trying to create a query where i can say i want to select a class.ID of lets say 12 and display both the Teachers name and the Assistants Name.
If i do just one join between Staff.ID and lets say Class.TeacherID all is fine and i can display the teacher.FirstName for a particular class.ID. However my problem is when im trying to display both teacher and assistant. Every time i try to create a query to do this the query comes back blank.
Im really stuck on this and just can't figure it out (is it even possible?).
