To Many Columns Or To Many Tables?
Feb 6, 2007
my supervisor is trying to help move our existing database in IBM U2 into SQL Sever
he has a file/table that as 12001 columns,
1 column is the key
300 columns are different field errors that can be checked true or false
and for each of those 300 columns there are three extra columns where extra information can be stored
is there a size limitation when it comes to columns in a SQL table?
what is an efficient way of doing this?
create one giant table with 12000 columns?
create 300 tables, each table associated with a error association? which will then need to be joined?
any suggestions? comments? tips?

I have 4 tables involved here. The priority table is TABLE1:
NAMEID TRANDATE TRANAMT RMPROPID TOTBAL
000001235 04/14/2014 335 A0A00 605
000001234 04/14/2014 243 A0A01 243
000001236 04/14/2014 425 A0A02 500
TRANAMT being the amount paid & TOTBAL being the balance due per the NAMEID & RMPROPID specified.The other table includes a breakdown of the total balance, in a manner of speaking, by charge code (thru a SUM(OPENAMT) query of DISTINCT CHGCODE
TABLE2
NAMEID TRANDATE TRANAMT RMPROPID CHGCODE OPENAMT
000001234 04/01/2014 400 A0A01 ARC 0
000001234 04/05/2014 -142 A0A01 ARC 228
000001234 04/10/2014 15 A0A01 ALT 15
[code]...
Also with a remaining balance (per CHGCODE) column. Any alternative solution that would effectively split the TABLE1.TRANAMT up into the respective TABLE2.CHGCODE balances? Either way, I can't figure out how to word the queries.

When I run below query I get 3 columns, but when I try to add table name ind.object_name (object_id) it's giving me an error "Ambiguous column name 'object_id".How do I add tables name with 3 columns?
SELECT ind.name, ic.index_id , ind.type_desc from sys.indexes ind
INNER JOIN
sys.index_columns ic ON ind.object_id = ic.object_id and ind.index_id = ic.index_id
INNER JOIN
sys.columns col ON ic.object_id = col.object_id and ic.column_id = col.column_id
INNER JOIN
sys.tables t ON ind.object_id = t.object_id

I am trying to index through the columns of MyTable so I can do the same work on all columns. I know how to get the column names from MyTable but when I use @MyColName in the SELECT statement to get MyTable Column 0 Row values I get a table with the column name in each row cell. I can't get the syntax correct to return the value in each cell for that column.
This is a extremely simplified example !!!!!!DECLARE @MyColName nvarchar(30)
--Get the MyTable Column 0 NameSELECT @MyColName = Col_Name(Object_ID('MyTable'), 0)
--Display the MyTable Column 0 Row valuesSELECT @MyColName FROM MyTable --This is the syntax I can not get correct
Can anyone help ?
Thanks

Hey all. I apologize, but I'm a developer, not a DBA. I need to run a query that will list each table in a DB as well as the columns i nthose tables.
I know that you can use: EXEC sp_help 'table_name' to get a description, but I'm not sure how to set up a cursor to substitute the table names, or where to get the tables names.
Any help would be greatly appreciated. Thanks!

I have several tables that I need to sum up a colomn and display the results. I have been struggling with this for some time. Here are my Tables and their columns:
Ingredients_tbl
IngredientID
Description
Inventory_tbl
IngredientID
AmountRemaining
Renconciled
Active
Order_Details_tbl
IngredientID
OrderAmount
Status
Order_Details_Details_tbl
IngredientID
OrderAmount
Status
I want to display all the ingredients from the ingredients table, sum the amountremaining of the items that are reconciled = 'false' from the inventory_tbl, sum the orderamount from both the order_details_tbl and Order_details_details_tbl for each ingredient based on status. Here is some sample data and results I am looking for:
Ingredients_tbl
IngredientID -- Description
1 -- Corn
2 -- Beer
3 -- SBM
4 -- Wine
Inventory_tbl
IngredientID -- AmountRemaining -- Reconciled
1 -- 500 -- False
1 -- 500 -- False
1 -- 100 -- True
1 -- 500 -- False
2 -- 1000 -- False
2 -- 1000 -- False
4 -- 500 -- False
4 -- 500 -- False
Order_Details_tbl
IngredientID -- OrderAmount -- Status
1 -- 100 -- ORDERED
1 -- 100 -- MIXED
1 -- 100 -- DELIVERED
2 -- 100 -- ORDERED
3 -- 100 -- ORDERED
3 -- 100 -- ORDERED
3 -- 100 -- ORDERED
4 -- 100 -- ORDERED
4 -- 100 -- DELIVERED
Order_Details_Details_tbl
IngredientID -- OrderAmount -- Status
1 -- 100 -- ORDERED
1 -- 100 -- DELIVERED
1 -- 100 -- DELIVERED
2 -- 100 -- ORDERED
3 -- 100 -- ORDERED
3 -- 100 -- ORDERED
4 -- 100 -- ORDERED
I would like the results to be like this:
IngredientID
Description
Inventory = Sum of AmountRemaining of the records in Inventory_tbl where Renconciled = 'false'
Production1 = sum of OrderAmount of the records in the Order_Details_tbl where Status = 'ORDERED' Or Status = 'MIXED'
Production2 = sum of OrderAmount of the records in the Order_Details_Details_tbl where Status = 'ORDERED' Or Status = 'MIXED'
IngredientID -- Description -- Inventory -- Production1 -- Production2
1 -- Corn -- 1500 -- 200 -- 100
2 -- Beer -- 2000 -- 100 -- 100
3 -- SBM -- 0 -- 300 -- 200
4 -- Wine -- 1000 -- 100 -- 100
I thought this was going to be as easy as a few simple joins and aggregate sum on the colomns like this:
SELECT Ingredients_tbl.IngredientID, Ingredients_tbl.Description,
Ingredients_tbl.LowInventory, SUM(Inventory_tbl.AmountRemaining) AS Inventory, SUM(Order_Details_tbl.OrderAmount) AS Production1, SUM(Order_Details_Details_tbl.OrderAmount) AS Production2
FROM Ingredients_tbl
LEFT OUTER JOIN Inventory_tbl ON Inventory_tbl.IngredientID = Ingredients_tbl.IngredientID AND Inventory_tbl.Reconciled = 'False'
[Code] .....
But this obviously has its issues with incorrect returned sum values.

I am using the JOIN function to pull data from two tables. Table_A has all columns I need; Table_B contains only 1 column I need. The column I need data from in Table_A is called CITY_NAME and stops May 1st. The column I need in Table_B (which has the same values but begins May 2nd) is labeled CITY. In Table_A I have NULL values starting Mat 1st for CITY_NAME. In Table_B, I have NULL values for any date before May 2nd.
I need to replace the NULL values in table B (May 1st and forward) with the values that are in Table B
SELECT
a.DATE,
a.STATE,
b.CITY
FROM TABLE_A a
LEFT JOIN TABLE_B b ON a.ID = b.ID
I need to use a function similar to UNION, but TABLE_A has 10 columns and TABLE_3 has 3 columns.

Hi,I've enherited a big mess, a SQL Server 2000 database withapproximately 50 user tables and 65+ GB data, no explicitrelationships among entities (RI constraints whatsover), attempt tocreate an ERD would more than likely kill the relatively complexedapp, the owner would want to drop out of window, so,I don't intend to do that, you get the picture, sorry no DDLs thistime, and many tables have many nullable columns, joins slows down thesystem quite a bit, what's my best bet to improve its performance?change most of these nullable columns into non-nullable with defaultvalue of something like ' ', any thoughts along this line would beappreciated.

I have two tables that contain product SKUs (12-character strings):
Table 1Product IdSKU...
Table 2ProductVariantIdSKU...
I need to find the MAX (i.e., last used) SKU that exists in either table. I did write two sps, one for each table that I can compare in code and use the larger (latest) one but I am not that facile with JOINS, etc., so I can't figure how how to create a single sp to return the value I am looking for--although I assume this must not only be possible but trivial to more experienced SQLers.
Thanks!

I have a db which I have little control over most of it's makeup because of the vendor supplied tools. We currently have over 700 tables and 19000 columns. Has anyone seen a problem or saturation pont with these kinds of numbers? The database delivered to the clients will be from 2-50 gig depending on the site. I can probably through hardware at problems, but if anyone has been down this road any suggestions are appreciated.

I'm having a very irritating time trying to migrate data from a COBOL system to SQL Server.
One of the A/R Master files has approx. 200 columns.
I can export this file any number of ways that will (sometimes) load partially into my database, but always when the load succeeds, columns 75 through N simply contain NULL, even though there is data in the file. When the load fails in DTS, the error is always missing column delimiter. Using BULK INSERT the error is always something like data too long at column 75.
Putting all this together, I have deduced that something isn't working if I try
to load a staging table with more than 74 columns of data. This seems like a way-too-low threshold for a robust database, especially since SQL Server is supposed to be able to handle up to 1,024 columns per table.
Has anyone ever encountered this problem?
Thanks in advance for any help

I am having a problem with using UDF as part of a temp table computed column. Here's the sample code:
IF EXISTS( SELECT 1 FROM information_schema.routines WHERE routine_name = 'fn_test')
DROP FUNCTION dbo.fn_testGO
CREATE FUNCTION dbo.fn_test( @x int, @y int)
RETURNS INT AS
BEGIN
DECLARE @z INT
SET @z = @x + @y
RETURN @z
END
GO
CREATE TABLE #X
(
x INT,
y INT,
z AS (dbo.fn_test(x,y))
)
I receive the following error:
Server: Msg 208, Level 16, State 1, Line 2
Invalid object name 'dbo.fn_test'.
I do not get this error if I use a regular table.
HELP!

Hi,
How do I add comments to tables / columns in SQL Server ? Oracle supports adding comments to tables / columns using "comment on table / column" statement. Is a similar feature available in SQL Server 2000 ?
Any help folks ?

Hi folks,
I need to execute some kind of
select a,b,c into #inserted from inserted
a = int
b = varchar(50)
c = text
Easy so far. But I what I need is to find out whether the audited table contains text(or nText / image) columns or not. If it contains any text columns the statement should automatically be changed to
select a,b into #inserted from inserted
Remember that the trigger must be usable for any table in the database without manually entering the tables structure or the column names.
Best would be fetching the structure fropm the system views (INFORMATIONSCHEMES)
Any suggestions ?
Thanks a lot!
Stefan

For every table in my database there is a duplicate table with same columns. For example, employee is the name of main table, there is employee_dup table in same database.
There is only one column extra in _dup tables i.e.,idn column.
Now, I want to know all the columns present in main table which are not present in corresponding _dup table. There might be a chance of missing one or two columns in _dup tables. So i want a query to find out all the columns present in main table that are not present in hx table.

I am trying to write an SQL command for my crystal report. I need to compare the same column in 3different tables & get the data from each table for only the matching data.. I understand I need to create a temporary table, get the data into it & then work around.. I am quite new to SQL.
Eg: Considering one customer account
Table 1
Cust.No Name Amt_Counter AmtPaid
123.456 sam 0 0
123.456 sam 1 50
Table 2
Cust.No Name Freq_Counter Frequency
123.456 sam 1 0
123.456 sam 2 15

The following returns all base tables within the database of type "varchar":
Code:
SELECT TABLE_SCHEMA, TABLE_NAME, COLUMN_NAME FROM mydb.information_schema.columns
WHERE TABLE_SCHEMA = 'master' AND TABLE_CATALOG = 'mydb'
AND DATA_TYPE IN('varchar')"
AND TABLE_NAME IN(
SELECT TABLE_NAME FROM mydb.information_schema.tables
WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_CATALOG = 'mydb' AND TABLE_SCHEMA = 'master')
What I then want to do is... For each of these results:
Code:
select [COLUMN_NAME] from [TABLE_SCHEMA].[TABLE_NAME]
WHERE ID = 'test'
Is it possible to do this in one SQL command? Or do I manually have to do it for each in the list from my first query?

I have one database with several tables in it (table 1, table2, table3). In each table is two colums (colum1 = a number (201220) and colum2 = a number (0.50). Now, both tables will have rows with the same data in colum 1, but colum two will have different numbers (different prices). My goal is to run a query that will compare both colums in all three tables, take the lower of the three based on colum 2 and spit out the row. Obviously, this would output all rows (around 175k). The point is to create a least cost spreadsheet (csv) file based on evaluating all three tables.
