ODBC is a database which is used to store huge numbers of data and also help to backup of files. It is the collection of database which stores the data in separate columns and can be modified easily. Basically this application is used in the back end of the program. When user insert, update, delete, select then the records stored or retrieved from this database. It stands for Open Database Connectivity which is the product of Microsoft. Sometime during connecting to the database you may receive the error message that-
ODBC Error: Data Source Name Not Found and No Default Driver Specified
The error message specifies that you are missing to give the Data Source name or the driver is not specified for the ODBC.
Cause of this error:-
As we know that driver is the most important part of the system and it helps to communicate to hardware, software and operating system so if the driver is not specified for the ODBC then you can’t use this database to store the data and if you will try then you will receive the error message. Sometime user mistake to give the name of the Data Source or the Data Source is unable to found to the desired location so in that condition you may also receive the error message. If the Data Source is correctly specified but you have not the permission to access that Data Source then in that condition you may also receive the same error message.
How to fix this error:-
If you are getting ODBC error- Data Source Name Not Found and No Default Driver Specified then you can fix it manually because it is not a big problem. Generally the user mistake to give the name of the Data Source so due to missing of the Data Source he/she receives the error message. Go to the connectivity part where you have written the name of the Data Source and be sure that it is correct. If it correct then also be sure that its path is correct and you have permission to access it. If you have not the permission the get the permission then try. You must also be sure that the driver is specified for the ODBC because its missing may be problematic. Always protect the system from malicious programs because they can change the setting, corrupt database, driver etc. If you proper maintain the system and follow the given instructions of this paragraph then you can solve this problem easily.
