compare two columns in two data tables



is there an easy way to compare two columns in two datatable to see if they match?

I need to check if the values in column["x"] of datatable1 occur in column ["y"] of datatable2, without iterating through both tables (for each value in column of dt1, check column of dt2).

I tried:

foreach (DataRow dr in dt1.rows)

if (dt2.rows.find(dr["x"])

but this checks the whole row and if finds an "x" in any column, "if" condition is true. I need to only check one column of dt2.

Tables have different columns but the same primary column and that's what I need to check


MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

Set up a validator that compare the value of the current field with an other (using Dynamic Data)

Hi! Most of it is in the title : I'd like have a validator on the DateTime_Edit template for example that allows to compare this field with an other DateTime field. My problem is when I am in the DateTime_Edit template of my "master field" (the one I want to check), how can I access to the other field given the architecture of Dynamic Data FieldTemplates? But perhaps I'm not thinking in a good way on this control. Any advice will be welcome. Thanks Raphaelp

ASP.NET insertion and joining data between tables

I have the following tables:1.) PRODUCT_INFORMATION2.) CUSTOMERS3.) DISTRIBUTORS4.) PRODUCT_NAME5.) CONTROLLEREach table has a primary key assigned. The customers table has an ID column and a CUSTOMER_NAME column with unique index property set to avoid any duplication. How do I insert values in the product_information table that has a foreign key column from the CUSTOMERS table if we insert a value in the CUSTOMER_NAME field of the CUSTOMERS table. I want to know how can I create a join between all the tables so that when I insert values in individual tables they are joined with a serial number column in the PRODUCT_INFORMATION  table?Please suggest!!

Import a flat file with combined data into separate SQL tables using SSIS

I have a flat text file (comma delimited) that is essentially multiple files, each with its own format, combined into one file. The file is coming from an external software vendor so unfortunately we don't have much choice but to work with what we are receiving. Here is an example of what the file could look like: Customer Data CustID,FName,LName,PhNum,Email 12345,John,Smith,,jsmith@gmail.com 12346,Jane,Doe,8001111111,jdoe@hotmail.com Customer Plan CustID,PlanType,PlanName,PlanStart 12345,0,Plan1,01/01/2010 12345,2,PlanVis,01/01/2010 12346,3,PlanLf,04/01/2010 12346,0,Plan1,01/01/2010 Customer Payment CustID,LastPayment,Amount 12345,09/01/2010,100.00 12346,05/01/2010,50.00 There is an empty line between each 'section' of data. I adapted a VB script I found online that can take the incoming file and save off each section as its own file so that each one can be separately imported, but this seems inefficient. I'm really new to SSIS in general, but it seems like it shouldn't be that difficult to take the data, split it where there is an empty line, and then import each section into the appropriate SQL table. Any ideas would be most welcome. Thanks!

Join Tables For Definitions (Data Table/Definition Table)



I am well versed with Join/Outer Join/Inner Join. My question is not related to normal Joining of two tables. Its little complex. Let me see if I can explain well.

There are two tables, were data is stored.

Name_Info : nvarchar(10)
Date_Info : smalldate()
Spec_Info_1 : tinyint
Spec_Info_2 : tinyint
Spec_Info_3 ; tinyint

Name_Data : nvarchar(10)
City_Data : nvarchar(10)
State_Data : nvarchar(10)

To join these two tables, I use the following query (joined on Name_Info ON Name_Data)


SELECT Name, Date=CONVERT(varchar, Date, 101), City, State,
CASE Spec_Info_1 WHEN '0' THEN 'House' WHEN '2' THEN 'Shop' WHEN '3' THEN 'Bay' ELSE '-' END AS Spec_Info_1, 
CASE Spec_Info_2 WHEN '0' THEN '10 Feet' WHEN '2' THEN '20 Feet' WHEN '3' THEN '40 Feet' ELSE '-' END AS Spec_Info_2, 
CASE Spec_Info_3 WHEN '0' THEN '2 Windows' WHEN '2' THEN '4 Windows' WHEN '3' THEN '6 Windows' ELSE '-'  END AS Spec_Info_3
FROM Table_Spec_Data LEFT OUTER JOIN Table_Name_Data On Table_Spec_Data.Name_Info=Table_Name_Data.Name_Data
