Exclude Records From A Table Where ID Column Is Same But Mail Code Column Is Multi-valued
Nov 12, 2012I am trying to exclude records from a table where the ID column is the same but the Mail code Column is multi-valued.For Example: (the table looks like....)
ID Mail_code
111111 XNT
111111 N11
111111 XNC
222222 XNC
222222 XNL
333333 XNC
So, if there is any ID that has a value of XNC, I want to exclude the ID all together from my output regardless of the other values.

Multi-column Index Vs Single Column Indexes
Aug 14, 2007Hi,Would like to know the performance differenece between Multi-columnIndex vs Single Column Indexes. Let's say I have a table with col1,col2, col3 along with a primary key column and non-indexed columns.In queries, I will use col1, col2, and col3 together and some timesjust one or two of these three columns. My questions is, should Icreate one index contains col1, col2, and col3, or create 3 seperatedcolumns. I.e. each column has its own index. Any performancedifference?Thanks a lot.

How To Do A Join Using Foreign Keys In Stored In A Database Column?
Apr 17, 2007I have a database column that stores a comma delimited list of foreignkeys. Would someone show me how to do a join using the values from alist stored within a record?For example, a record in tbl_cds.genre_id might have a value of "2,5, 6" corresponding to genre_ids 2 , 5 and 6. I want to jointbl_cds.genre_id to tbl_genre.genre_id using the values in that datafield.It seems I need a loop like this:SELECT * FROM tbl_cdsWHEREBegin Looptbl_cds.genre_id[i] = tbl_genre.genre_idEnd Loop.Would someone give me the correct syntax?Is there an alternative method that would create less overhead?Sorry for such a novice post.

Multi Column Index
Apr 22, 2008Hi there,
My 'where' clause contains the following...
startdate <= @Date AND enddate > @Date
Should I put one index on 'startDate' and another on 'endDate' or should I have one index that covers both columns?
I don't know what the difference would be.

Multi-column IN Clause
Nov 1, 2007
Hi,
I have a [TestTable] table with three rows. The pair of columns [Test1] and [Test2] are id, the [Test3] is a data column. First, I get a table variable with list of id pairs. Next, I would like to update the rows of that ids. However, I have not found the elegant way how to do it. For one column it is simple, just IN clause, which does not work (or I could not find how) for multi-columns. Does someone have a hint?
Thanks,
Martin
Note: The example bellow is dummy; on the other hand, I hope it shows the important points. Please, do not beat me on syntax errors.
Code Block
DECLARE @MyTableVar table(
Test1 int NOT NULL,
Test2 int NOT NULL
);
SELECT [Test1],[Test2] INTO @MyTableVar FROM [TestTable] WHERE [Test3] = '%dd%';
UPDATE [TestTable] SET [Test3] = [Test3] + 'ds'
WHERE ([Test1], [Test2]) IN (SELECT [Test1], [Test2] FROM @MyTableVar);

Creating Inter-table Relationships Using Primary Keys/Foreign Keys Problem
Apr 11, 2006Hello again,
I'm going through my tables and rewriting them so that I can create relationship-based constraints and create foreign keys among my tables. I didn't have a problem with a few of the tables but I seem to have come across a slightly confusing hiccup.
Here's the query for my Classes table:
Code:
CREATE TABLE Classes
(
class_id
INT
IDENTITY
PRIMARY KEY
NOT NULL,
teacher_id
INT
NOT NULL,
class_title
VARCHAR(50)
NOT NULL,
class_grade
SMALLINT
NOT NULL
DEFAULT 6,
class_tardies
SMALLINT
NOT NULL
DEFAULT 0,
class_absences
SMALLINT
NOT NULL
DEFAULT 0,
CONSTRAINT Teacher_instructs_ClassFKIndex1 FOREIGN KEY (teacher_id)
REFERENCES Users (user_id)
)
This statement runs without problems and I Create the relationship with my Users table just fine, having renamed it to teacher_id. I have a 1:n relationship between users and tables AND an n:m relationship because a user can be a student or a teacher, the difference is one field, user_type, which denotes what type of user a person is. In any case, the relationship that's 1:n from users to classes is that of the teacher instructing the class. The problem exists when I run my query for the intermediary table between the class and the gradebook:
Code:
CREATE TABLE Classes_have_Grades
(
class_id
INT
PRIMARY KEY
NOT NULL,
teacher_id
INT
NOT NULL,
grade_id
INT
NOT NULL,
CONSTRAINT Grades_for_ClassesFKIndex1 FOREIGN KEY (grade_id)
REFERENCES Grades (grade_id),
CONSTRAINT Classes_have_gradesFKIndex2 FOREIGN KEY (class_id, teacher_id)
REFERENCES Classes (class_id, teacher_id)
)
Query Analyzer spits out: Quote: Originally Posted by Query Analyzer There are no primary or candidate keys in the referenced table 'Classes' that match the referencing column list in the foreign key 'Classes_have_gradesFKIndex2'. Now, I know in SQL Server 2000 you can only have one primary key. Does that mean I can have a multi-columned Primary key (which is in fact what I would like) or does that mean that just one field can be a primary key and that a table can have only the one primary key?
In addition, what is a "candidate" key? Will making the other fields "Candidate" keys solve my problem?
Thank you for your assistance.
Creating Indexes On Columns That Are Foreign Keys To Primary Keys Of Other Tables
Jul 16, 2014what the best practice is for creating indexes on columns that are foreign keys to the primary keys of other tables. For example:
[Schools] [Students]
---------------- -----------------
| SchoolId PK|<-. | StudentId PK|
| SchoolName | '--| SchoolId |
---------------- | StudentName |
-----------------
The foreign key above is as:
ALTER TABLE [Students] WITH CHECK ADD CONSTRAINT [FK_Students_Schools]
FOREIGN KEY([SchoolId]) REFERENCES [Schools] ([SchoolId])
What kind of index would ensure best performance for INSERTs/UPDATEs, so that SQL Server can most efficiently check the FK constraints? Would it be simply:
CREATE INDEX IX_Students_SchlId ON Students (SchoolId)
Or
CREATE INDEX IX_Students_SchlId ON Students (SchoolId, StudentId)
In other words, what's best practice for adding an index which best supports a Foreign Key constraint?
Multi Column Subquery? W/ Alias
Jun 12, 2008What I need to do is to create 3 columns with 3 different aliases from the same table that will return all the values during the following conditions:
when pricelist = 1
when pricelist = 2
when pricelist = 3
pricelist
--------
1
2
3
Price
--------
912 -- (linked with 1)
234 -- (linked with 3)
56 -- (linked with 2)
3245 -- (linked with 3)
234 -- (linked with 1)
65 -- (linked with 2)
these 2 columns are in the same table^^
so what i want my query to generate is:
Price1
--------
912
234
Price2
--------
56
65
Price3
--------
234
3245
Any help is apprecieated, thanks
if the above does not make sense to you maybe this will:
"can you make 3 aliases of the same column and only display the rows inside each column where pricelist = 1 for the 1st alias... where price = 2 for the 2nd alias...where pricelist = 3 for the 3rd alias"

Any suggestion on what is the problem and even better, if there is a solution.
Multi Column Report With Graph
Oct 29, 2007
Hi,
I have created a multi column report (2 columns), which is working fine. However, I need to have a chart on the same report, but it needs to be the width of the page, and not just the width of one column.
If I could put the chart in the report footer / header that would be perfect, but obviously I can't!
Has anyone else come across this, and any ideas / suggestions you have would be appreciated!

Multi-column Report Problem
Apr 12, 2007I am trying to get a simple list to wrap and print in multiple columns on my report. I have indicated 3 multi-columns in the report properties and see the multiple columns in the layout, but I must need to do something else because the report is still printing in one column to multiple pages. This should all fit on 1 page if the list will wrap or snake as it says it the directions for using multi-column reports.
Any help would be appreciated. Thanks

T-SQL (SS2K8) :: Query Column With Multi Values Using IN?
Aug 26, 2014I am working with a table that has a column which stores multiple data/values that are comma separated.
I need to be able to query that table and get those rows where the values in that column match a pre-defined search list.
I was thinking of somehow trying to take the search list and convert it to a table(temp or a cte) and then JOIN to the table.
however, since the column may contain multiple values, i would need to parse/separate that first. I am not sure how to parse and then join to a list (if that is even the best way to solve this) to only get the rows where the search column contains one or more of the items we're looking for.
Below is some sample data:
Declare @BaseTable table (PKCol int, Column2Search varchar(2000))
Insert into @BaseTable (PKCol, Column2Search)
Select 1001, 'apple,orange,grapefruit'
UNION ALL
Select 1002, 'grapefruit,coconut'
UNION ALL

Multi-column Report Page Header
Aug 2, 2007I have a multi-column report with a page header that spans the width of the report. Whenever I close the report and reopen it, the header is changed to the width of the column. This isn't a real big deal because I deploy it with the header across the whole page; but once in a blue moon I accidentally hit the F5 key (which I am used to using for refresh in other environments I work in) and the report gets redeployed with the messed up header. Is there anyway to stop RS from automatically adjusting the page header?
And is there anyway to disable the F5 key from deploying the reports. I do use it to build and run windows apps, and don't want to change that, but I don't want to deploy 80+ reports when I accidentially hit it.
Thanks.
Multi-Column Export Rendering Issues
May 30, 2007I created an SSRS Multi-Column Report that sets the Column-Spacing to 0 inches.
However, when I export the report to PDF the columns are approxiametly .125 inches apart from one another.
I need the columns to butt up against each other as I want to print the contents on a perforated label.
Does anyone know why this happens or how to enforce the column spacing?
Thanks!
Multi Column Primary Key's In Access Using ADOX [c#]
Jan 15, 2008Hi all,
I have been pulling my hair trying to figure out what the guys at microsoft were thinking when creating the ADOX library. I have an access table that is syncronized with a SQL server. The table has a primary key with two columns [User] and [Program]. The SQL Server has both columns in as the primary key columns and I have a syncronization mechanism that is responsible for several things, one of which is to recreate the Access data structure. All works well for all tables except this one. I have tried to create the multi-column key in several ways, none that worked. Let me show you what I am doing:
CatalogClass catDCDLocal;
Column c;
catDCDLocal = new CatalogClass();
catDCDLocal.let_ActiveConnection(dbAccess.buildConnectionString(Settings.CattDCDLocalPath, Settings.SecurityDBPath, s.UserID, s.Password));
foreach (Table tbl in catDCDLocal.Tables) {
if (tbl.Name == "Users") {
/* This is retarded so need to clean up... Users table has a primary key consisting of 2 columns */
for (int i = tbl.Keys.Count - 1; i >= 0; i--) { //remove the keys
tbl.Keys.Delete(i);
}
for (int i = tbl.Indexes.Count - 1; i >= 0; i--) { //remove the indexes
tbl.Indexes.Delete(i);
}
tbl.Keys.Append("PrimaryKey", KeyTypeEnum.adKeyUnique, "User", "", "");
tbl.Keys[0].Columns.Append("Program", DataTypeEnum.adWChar, 6);
}
}
I have also tried:
tbl.Keys.Append("PrimaryKey", KeyTypeEnum.adKeyUnique, "User", "", "");
//tbl.Keys[0].Columns.Append("Program", DataTypeEnum.adWChar, 6);
Key k = tbl.Keys[0];
Column col = tbl.Columns["Program"];
//col.ParentCatalog = catDCDLocal;
k.Columns.Append(col, DataTypeEnum.adWChar, 6);
Nothing works for me ;-(
