Using A Match Table To Store Multiple Columns For Parent Data
Mar 1, 2008
Sorry for the confusing subject. Here's what im doing:
I have a table of products. Products have N categories and
subcategories. Right now its 4. But there could be more down the
line so it needs to be extensible.
So ive created a product table. Then a category table that has many
categories of products, of which a product can belong to N number of
these categories. Finally a ProductCategory "match" table.
This is pretty straigth forward. But im getting confused as to how to
write views/sprocs to pull out rows of products that list all the
products categories as columns in a single query view.
For example:
lets say productId 1 is Cap'n Crunch cereal. It is in 3 categories:
Cereal, Food for Kids, Crunchy food, and Boxed.
How do I go about writing a query that returns a single result set for
a view or data set (for use in a GridView control) where I would have
the following result:
I have an Parent table (Parentid, LastName, FirstName) and Kids table (Parentid, KidName, Age, Grade, Gender, KidTypeID) , each parent will have multiple kids, I need the result as below:
I'd like to first figure out the count of how many rows are not the Current Edition have the following:
Second I'd like to be able to select the primary key of all the rows involved
Third I'd like to select all the primary keys of just the rows not in the current edition
Not really sure how to describe this without making a dataset
CREATE TABLE [Project].[TestTable1]( [TestTable1_pk] [int] IDENTITY(1,1) NOT NULL, [Source_ID] [int] NOT NULL, [Edition_fk] [int] NOT NULL, [Key1_fk] [int] NOT NULL, [Key2_fk] [int] NOT NULL,
[Code] .....
Group by fails me because I only want the groups where the Edition_fk don't match...
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select Test_Name AS 'Test_Name', Table_Bird.Animal AS 'Birds', Table_Mammal.Animal AS 'Mammal', Table_Reptile.Animal AS 'Reptile, Table_Fish.Animal AS 'Fish' From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.* FROM PRODUCT A CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below)Â and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.* FROM PRODUCT A CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, Â fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.
1 2015 ba1 137 HL EL Eco 2 2015 ba1 138 EL SL HS 3 2015 ba1 139 SL EL His
From this table i use to admit a student and select their choice of group simultaneously all the subjects associated with GROUP is save on another table.
Here is the TABLE 2 Structure and sample data:
table 2 (NAME - tblstudetail)
id studentID session course sub1 sub2 sub3
1 15120001 2015 ba1 EL SL HS 2 15120002 2015 ba1 HL EL Eco 3 15120003 2015 ba1 SL EL His 4 15120004 2015 ba1 HL EL Eco
AND so no..........................
Now i just want to COUNT the Number of Groups Filled in tblStudateil.
I am facing a problem in writing the stored procedure for multiple search criteria.
I am trying to write the query in the Procedure as follows
Select * from Car where Price=@Price1 or Price=@price2 or Price=@price=3 and where Manufacture=@Manufacture1 or Manufacture=@Manufacture2 or Manufacture=@Manufacture3 and where Model=@Model1 or Model=@Model2 or Model=@Model3 and where City=@City1 or City=@City2 or City=@City3
I am Not sure of the query but am trying to get the list of cars that are to be filtered based on the user input.
Running SQL Server 2005, trying to develop an SSRS report to basically pivot a table of data with multiple columns.
Here's the basic source table:
Day   Cases  Referrals   Vends 1        291         0            0 2        293         1            0 3        293         1            1
And I want to display it as:
Day            1      2       3 Cases        291   293  293 Referrals      0       1     1 Vends          0        0     1
I thought I could use a matrix for this but I can't seem to get it worked out. Is this even possible?
The Day number is meant to represent the day of the month and the user would input a start and ending date parameter.
I have a data flow task in which there is a OLEDB source, derived column item, and a oledb destination. My source is a SQL command, that returns some values. I have some values, that I define in the derived columns, and set default values under the expression column. My question is, I also have some destination columns which in my OLEDB destination need another SQL command. How would I do that? Can I attach two or more OLEDB sources to one destination? How would I accomplish that? Thanks
I've a question about how to implement a scenario, and would appreciate any suggestions anyone cares to offer.
I'm creating the following tables
FutureContract Equity
These (and others), may have an option placed on them, I was planning to create seperate option tables for each i.e. FutureContractOption EquityOption
With a FK pointing at the PK of the tables above.
However the data held in the option table looks the same for both, and I'm considering trying to use the same Option table for both the FutureContract & Equity tables.
There is a problem here with the Foreign key referencing the Primary key of the parent table.
I could add two foreign key columns and allow them to be null, so that only one is entered, however we can have an option on a lot of different things, so I might end up with a great list of these columns. Table - Option FK - FutureContractPK FK - EquityPK I'm using an unique number (identifier) column for the primary key of all tables.
I'm sure this is a relatively common problem, and would be grateful for any suggestions about how I might approach this.
I want to compare two columns in the same table called start date and end date for one clientId.if clientId is having continuous refenceid and sartdate and enddate of reference that I don't need any caseopendate but if clientID has new reference id and it's start date is not continuous to its previous reference id then I need to set that start date as caseopendate.
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped: [Department, DEP_CLEGALCODE] One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
I am rather new to reporting on SQL Server 2005 so please be patient with me.
I need to create a report that will generate system information for a server, the issue im having is that the table I am having to gather the information from seems to only allow me to pull off data from only one row.
For example,. Each row contains a different system part (I.e. RAM) this would be represented by an identifier (1), but I to list each system part as a column in a report
The table (System Info) looks like:-
ID | System part | 1 | RAM 2 | Disk Drive 10| CPU 11| CD ROM |
Which
So basically I need it to look like this.
Name | IP | RAM | Disk Drive| ---------------------------------------------- A | 127.0.0.1 | 512MB | Floppy
So Far my SQL code looks like this for 1 item SELECT SYSTEM PART FROM System Info WHERE System.ID = 1
How would I go about displaying the other system parts as columns with info
I need some store procedure script , from two table i want to pickup matching field and insert into main table ,give some sample store procedure coding...
If 1st table as cheque no and 2nd table as cheque no - matching then data would be inserted in to main table using two table...
I'm using the XML Source to process a hierarchical set of XML. As such, the XML Source creates keys to maintain the hierarchy. This is very convenient, and keeps me from having to invent my own keys.
The problem is that the datatype of these keys defaults to DT_UI8. Which SQL Server 2005 datatype should I use to store these values in my staging tables? BIGINT corresponds to DT_I8, which can't accept DT_UI8 values.
I am in the process of creating a Report, and in this, i need ONLY the row groups (Parents and Child).I have a Parent group field called "Dept", and its corresponding field is MacID.I cannot create a child group or Column group (because that's not what i want).I am then inserting rows below MacID, and then i toggle the other rows to MacID and MacID to Dept.
Hello,I have a query that I need help with.there are two tables...Product- ProductId- Property1- Property2- Property3PropertyType- PropertyTypeId- PropertyTypeThere many columns in (Product) that reverence 1 lookup table (PropertyType)In the table Product, the columns Property1, Property2, Property3 all contain a numerical value that references PropertyType.PropertyTypeIdHow do I select a Product so I get all rows from Product and also the PropertyType that corresponds to the Product.Property1, Product.Property2, and Product.Property3ProductId | Property1 | Property2 | Property3 | PropertyType1 | PropertyType2 | PropertyType3 PropertyType(1) = PropertyType for Property1PropertyType(2) = PropertyType for Property2PropertyType(3) = PropertyType for Property3I hope this makes sence.Thanks in advance.
I have two tables table1 and table2. I want to check a value from table1 against 4 different columns in table 2. What would be the most optimized way to do this. I came up with this SQL but it runs forever.
select * from table1 a where (a.id in (select orig_id from table2 where exctn_dt >= '01-OCT-14')) or (a.acct_intrl_id in (select benef_id from table2 where exctn_dt >= '01-OCT-14')) or (a.acct_intrl_id in (select send_id from table2 where exctn_dt >= '01-OCT-14')) or (a.acct_intrl_id in (select rcv_id from table2 where exctn_dt >= '01-OCT-14'));
In short: I want my following problem to work with a LIKE instead of exact match and if possible be faster. (currently 4s)
Problem: I got a set of rows with varchar(50), spread out over multiple tables. All those tables relate to a central Colour table. For each of the columns, I want to match the values with a set of strings I insert and then return a set of Colour.Id
E.g: input: 'BLACK', 'MERCEDES', '1984' Would return colour ids "025864", 45987632", "65489" and "63249" Because they have a colour name containing 'BLACK' or are on a car from 'MERCEDES' or are used in '1984'.
Current Situation: I) Create a table containing all possible values CREATE TABLE dbo.CommonSearch( id int IDENTITY (1, 1) NOT NULL, clr_id int, keyWord varchar(40), fieldType varchar(25) And fill it with all the values (671694 rows) ) II) Stored Procedure to cut a string up into a table: CREATE FUNCTION dbo.SplitString ( @param varchar(50), @splitChar char = '' ) RETURNS @T TABLE (keyWord varchar(50)) AS BEGIN WHILE LEN( @param ) > 0 BEGIN declare @val varchar(50) IF CHARINDEX( @splitChar, @param ) > 0 SELECT @val = LEFT( @param, CHARINDEX( @splitChar, @param ) - 1 ) , @param = RIGHT( @param, LEN( @param ) - CHARINDEX( @splitChar, @param ) ) ELSE SELECT @val = @param, @param = SPACE(0) INSERT INTO @T values (@val) END RETURN END III)Stored Procedure to query the first table with the second one CREATE PROCEDURE [dbo].[GetCommonSearchResultForTabDelimitedStrings] @keyWords varchar(255) = '' AS BEGIN SET NOCOUNT ON; select clr_id, keyWord, fieldType from dbo.commonSearch where keyWord in (select * from splitString(@keyWords, '')) END
So, how can I use a LIKE statement in the IN statement of the last query. Furthermore, I was wondering if this is the best sollution to go for. Are there any better methods? Got any tuning tips to squeeze out an extra second?
Now, I want to check whether all the codes in table1 existing in table2 and list them, and if both columns from table1 is matching with the both columns in table2. For e.g. 256|abc in table1 is matching with 256|abc in table2
I need to create an function similar to the "MATCH" function in Excelthat evaluates a number within a set of numbers and returns whetherthere is a match. I have put the example of what I see in excel in thecheck column. The "0" answer in the result column is in the fourthaccount in the list. Somehow I need to loop through the accountscomparing the result to the total and indicate a match in the checkcolumn. It wouldn't even need to tell me the row number; it could be a0 or 1.account total result check123770266.84124.2112377026131.050 412377026164.38-33.33123770260131.051237702678.7152.3412377167-31.34221.891237716731.34159.211237716738.55152 51237716731.34159.211237716715238.5512377167490.91-300.36123771670190.55123771670190.5512377167-31.3443.341237716731.34-19.341237716738.55-26.551237716731.34-19.3412377167152-14012377167490.91-478.9112377167012123771670121237736347.058412377363131.05012377363-45.38176.4312377363-47.05178.11237736347.0484.0112377363-47.04178.091237736347.058412377363541.11-410.06123773630131.0512377363672.15-541.11237750737.64152.91
I am creating a report that contains a table. The table only has one column containing 10 characters so there is a lot of wasted space on the page. I would like the columns to wrap to at least two columns on each page. I have tried to set the number of columns on the report properties to two, however it seems as if the second column is disabled and the data does not wrap into the second column when the report is run.
Hi,I have some tables where I import data in, lots of field have gotten aNULL value which the application can not handle.Now can I replace each NULL value with '' in a columns with:update <tableset [<column>] = '' where [<column>] IS NULLBut because there are lots of columns this is pretty much work, alsothere are multiple tables.Is there an easy way to replace all NULL values in all columns in atable?Thanks in AdvanceBob
