In selenium contents Walter Payton Jersey , when there is a need of getting the Data from the database we may need to utilize APIs which communicates with database like JDBC. Java Database Connectivity (JDBC) is a Java API which is utilized to associate and collaborate with Database.

uteQuery("Select * from Employee");

Naturally Resultset reference 'rs' focuses to before first column. it moves rs to next line and returns genuine. When it returns genuine we recover the information in first column. next() returns false when rs focuses to after the last column. this next() will rehashes the execution utilizing while circle till it returns false.
To refresh records in a table we utilize a technique called executeUpdate(String str) which returns whole number an incentive as what number of records have been refreshed.
