19;What is Database testing?

here database testing means test engineer should test the data integrity, data accessing,query retriving,modifications,updation and deletion etc

Database tests are supported via ODBC using the following functions:
SQLOpen, SQLClose, SQLError, SQLRetrieve, SQLRetrieveToFile, SQLExecQuery, SQLGetSchema and SQLRequest.
You can carry out cursor type operations by incrementing arrays of returned datasets.

All SQL queries are supplied as a string. You can execute stored procedures for instance on SQL Server you could use “Exec MyStoredProcedure” and as long as that stored procedure is registered on the SQL Server database then it should execute however you cannot interact as much as you may like by supplying say in/out variables, etc but for most instances it will cover your database test requirements

Data bas testing basically include the following.
1)Data validity testing.
2)Data Integritity testing
3)Performance related to data base.
4)Testing of Procedure,triggers and functions.

for doing data validity testing you should be good in SQL queries
For data integrity testing you should know about referintial integrity and different constraint.
For performance related things you should have idea about the table structure and design.
for testing Procedure triggers and functions you should be able to understand the same.

Data base testing generally deals with the follwoing:
a)Checking the integrity of UI data with Database Data

c)Checking execution of stored procedures with the input values taken from the database tables
d)Checking the Data Migration .
