Is there a performance hit if I use CAPITOL LETTERS (like this) in column names for my SQL Server tables? Logically I would think that lower case letters would have better performance because they are smaller characters and easier to store.
View 4 RepliesI have found a stored proceedure that will convert a string from any format to initial caps followed by lower case letters. However, I'm such a newbie to SQL Server that I have no idea how to run the SP on a table.
Here is the stored proceedure: http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=581&lngWId=5
How would I get this to run within a query to update a field?
For example, I have a field called 'name' with records like:
3M <- should remain '3M'
123 INTERIORS <--- should be '123 Interiors'
ALLIED SIGNAL <-- should be 'Allied Signal'
Is there a way in SQL server to alias column names for a particular table and store the aliases somewhere such that you can access the aliases while querying? I have a table where I cannot change column names and I am trying to figure out if there is a way to alias them to make them more user friendly.
View 2 Replies View RelatedI have a field in a table that contains a different formula (varchar(1000)) for each record. It's along the lines of something like this, although each formula is different: ([ColumnA] - [ColumnB])/([ColumnC] - [ColumnD]). I plug that into a dynamic SQL statement so that it can get executed in a select statement.
Due to the variations of the formulas, checking for Divide by Zero, etc, we want to move this to a .NET method. We'd like to replace "ColumnA" and "ColumnB", etc., with the actual values so that we're passing something like (5-3)/(6-2). I haven't been able to figure out a way to do this without actually executing it. We don't want to pass the solution, but the equation filled with the actual values rather than the column names.
In a stored procedure I dynamically create a temp table by selecting the name of Applications from a regular table. Then I add a date column and add the last 12 months. See attachment.
So far so good. Now I want to update the data in columns by querying another regular table. Normally it would be something like:
UPDATE ##TempTable
SET [columName] = (SELECT SUM(columName)
FROM RegularTable
WHERE FORMAT(RegularTable.Date,'MM/yyyy') = FORMAT(##TempMonths.x,'MM/yyyy'))
However, since I don't know what the name of the columns are at any given time, I need to do this dynamically.
how can I get the column names of a Temp table dynamically while doing an Update?
How do I add column names as Total and SubTotal for NULL values.
SELECT DISTINCT
--[Group]
[Month]
,[Market]
,[Environment]
,[type]
, COUNT(*)

Hi
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.
Thanks.
I have a table that I'd like to change some of the data. All of the employee information is entered in all CAPS. Is there a way to change JANE DOE, to Jane Doe?
Also, there are instances like this example "DOE, JANE".
I would like this to be "Doe, Jane" (Naturally).
Hi,
Which is the best practice ?
1. Writing t-sql in All small (or)
2. Writing t-sql in All Caps
- thanks in advance

The objects "MYTEST2.TEST" and "mytest.TEST" in the FROM clause have the same exposed names. Use correlation names to distinguish them.use of fully qualified names is allowed without having to alias them.One workaround is changing compatibility mode to 80.Is there another (startup flag?).Reason for no alias: MS Reportbuilder doesn't provide them when building queries

As part of my backup routine, I have a SQL job for each DB which which is called "DB-NAME - Backup Job"
I need to put a script together to check that each database has a backup job associated to it.
select * From sys.sysdatabases where name not in ('msdb','model', 'master', 'Tempdb', 'DBA') order by name desc
select * from msdb.dbo.sysjobs order by name desc
I know all the details i need are in there, but i cant figure out the best way to tackle it. Do I need to do a cursor to go through each DB name, put it into a variable, then select the job name where name like '$variable%' ?

Hi
When I run this query..
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME='TableTest'
I get all the column names, but the result is not in the same order as when I check the design for the table, why is that?
At my work, we are upgrading a number of MS Access 2000 databases to SQL Server 2000. Many of the columns have names that do not follow the rules for Identifiers. For example there are columns with a numeric names 1,2,3,4,5,6,7,8,9. There are also columns with a hyphen in the name and columns that begin with a number and not an underscore or an alpha character. Plus there are columns with names like first, last, position, etc. (There was also columns with reserved words used as the names. I have changed those column names in the databases that I have already converted) Will leaving these names alone create a problem? The database serves as the backend to ASP pages.

I need to ensure some naming standards to users while creating tables.
All table name should be in same pattern
(ie., ) TeamName_EmpId_tablename
I need a way to restrict user to follow the naming standard. If any user tries to create table without the above naming standard system should not allow.
I'm getting a rule check fail "Long path names to files on SQL Server Installation media failed" when installing SQL 2012 Standard edition from a network share.

Hello,I'm still extremely novice to SQL and I've tried googling how to produce this result but I've been encountering a lot dynamic sql commands which isn't exactly what I want. If this is an ignorant question I do apologize but heres my scenario: I have a table with columns of the day, for instance: Monday_hasData (bit)Monday_DataAnd what I want to do is essentially pass in "Monday" as a parameter and rather than doing an If statement on each row, I would like to just like to do something like assign @dayCheck + "_hasData" to a variable and then use @dayCheck as part of my query. Is this possible or am I going to have to have 7 cases? Thank you for any input,Chance

Hi,
I have a table in which out of 20 columns, there will be data only in a few columns. So, I need to find those column names which have data in them. I was able to do it using the information_schema and using a cursor to loop through all the column names and find out which columns have data in them. But i need to know if there is a more efficient way of doing this without using the cursor. Can somebody please let me know how this can be done without using a cursor? Thank you.
Can anyone help me with a SQL statement that will list all the column names in a table please ?
I just want to list out the column name so that i can develop asp/vb more effectively than having to use SQLEM and Design table to see the field names.:confused:

Hi is possible to create dynamic column name

select
SUM(Case When table1_date BETWEEN dateadd(day,-6,@StartDate) and @StartDate then 1 else 0 end)AS [dateadd(day,-6,@StartDate)],
SUM(Case When table1_date BETWEEN dateadd(day,-13,@StartDate) and dateadd(day,-7,@StartDate) then 1 else 0 end)AS [dateadd(day,-13,@StartDate)]

i have a table with Monday, Tuesday, Wednesday. .... Sunday
i get the weekday by
select @stat = datename(dw, getdate()) which in this case is Wednesday
but when i do something like
select top 2 * from myTable
where 'myTable.'+@stat = 1
which is as same as
select top 2 * from myTable
where myTable.wednesday = 1
i receive a syntax error. how can i dynamically select myTable.Wednesday ?
i also tried using
select top 2 * from Intercon
where '@stat' = '1'
but then this doesn't return anything where it should.
any help?
Is there a way that you could get the column names for each table in a database using 1 query?
something like:
tbl colname
t1 catID
t1 catName
t2 prodID
t2 prodDesc
t3 cartID
...
...
I know it would be long, but I would just be searching through the saved output for specific names.
Hi All,
I was wondering how would I get the column names from a table? Not the results just a listing of column names. What is the command to get this information? I am using MS Access, but I posted here because MS SQL is the closest thing on this forum and the syntax is usually similar.
Thanks a bunch.
