How do you retrieve the values from tables by specifying the coloumn and row no in net?
In .NET, you can retrieve values from a DataTable by specifying the column and row number using the Rows and Columns collections. First, you access the specific row using DataTable.Rows[rowIndex] and then the desired column using DataRow["ColumnName"] or DataRow[columnIndex]. For example, to get a value from the first row and the second column, you would use dataTable.Rows[0][1]. Ensure that the indices are within the bounds of the DataTable's rows and columns to avoid exceptions.

Data from two or more tables can be connected by specifying a?
relationship or join condition between a common column in each table. This connection allows us to retrieve related data from multiple tables in a database query. Join conditions typically involve matching values between the related columns in the tables being joined.
What links two tables using a common field in both tables and extracts the relevant data from each?
A join operation links two tables using a common field and extracts relevant data. By specifying the common field in the ON clause of a SQL query, the database can combine rows from both tables based on matching values in that field. This allows data to be retrieved from multiple tables in a single query.

What is the significance of the outer union operation in database queries and how does it differ from other types of joins?
The outer union operation in database queries combines the results of two queries, including all rows from both queries. This differs from other types of joins, like inner joins, which only include rows that have matching values in both tables. Outer union can help retrieve data from multiple tables even if there are no matching values, providing a more comprehensive view of the data.
What is an inner join?
An inner join is a type of SQL operation that combines rows from two or more tables based on a related column between them. It returns only the rows that have matching values in both tables, effectively filtering out any records that do not meet the join condition. This is commonly used to retrieve related data, ensuring that the result set contains only the relevant information where there is a match.
In relational database when two tables have common field the link between tables is know as a hyperlink?
Actually, in a relational database, when two tables have a common field, the relationship between the tables is known as a foreign key constraint. This constraint ensures that values in the common field of one table correspond to values in another table, helping maintain data integrity and enabling queries across related tables.

Join query in sql server 2005?
Join query are basically of three types : 1) Cross Join -- That is use to retrieve data from two tables on a condition (optional), there we get m*n no. of records(m is no of rec in first table and n is the no. of records in another table) 2) Inner Join : we use this join to retrieve values from two tables that satisfies given matching condition : as :: select Product_Category from Product_Detail INNER JOIN Product_Scenerio ON Product_Detail.Product_Id = Product_Detail.Product_Id. Product_Scenerio . 3) Outer Join : this is used in three way: a) Left Outer Join -- it is used to retrieve records from both tables that satisfies given condition including all records from left(First) table whether it do not satisfy condition ...try it practically ** related columns in right table has NULL values in records b) Right Outer Join :: It is used when we want to fetch all records from right(second) table whether that do not match with condition specified with JOIN . ** related columns in right table has NULL values in records c) Full Outer Join :: It is combination of Inner join + left Outer join + right Outer join .Here we get all records from both tables that do not match condition .
What is subscript in Excel?
Subscripts are when values in text are put below the normal text, like when specifying bases in mathematics. It is the opposite to superscripting, where values are above the regular text, like st following 1 to specify first.
