The purpose of the project was to investigate how SQL is embedded in C#.
NET database applications as well as Java database applications.
You can use these components (or classes) with or without data providers.
The Data Set consists of a collection of tables, rows, columns and relationships.
query will receive the data in data set and then we will check the data set that is it empty or have some data in it. If the above condition is true then the data set ie ds is empty.
When returning results from SQL query I find that tables exists, but it has zero rows.
Answer 1: ADO stands for Active Data Object and ADO. For example, ODBC data providers work with ODBC data sources and Ole Db data providers work with OLE-DB data sources. NET components model and how they work together: See for more detail: Answer 3: A Data Set object falls in disconnected components series.
The data provider components are specifically designed to work with different kinds of data sources.
The article is actually a part of the document that made the project report for my undergraduate degree.Generally we will use Execute Reader object to bind data to datareader.To bind Data Reader data to Grid View we need to write the code like as shown below: Data Set Data Set is a disconnected orient architecture that means there is no need of active connections during work with datasets and it is a collection of Data Tables and relations between tables. You can select data form tables, create views based on table and ask child rows over relations.This means if you enable Connection pooling in the connection object, actually you enable the re-use of the connection to more than one user. NET uses a technique called connection pooling, which minimizes the cost of repeatedly opening and closing connections.Connection pooling reuses existing active connections with the same connection string instead of creating new connections when a request is made to the database.
