execute the following command from the command line with the correct values for options. -Dfile option locates the downloaded jar file. Therefore make sure to specify the correct location or reach the jar location from the command line and execute the command. mvn install:install-file -DgroupId=ojdbc -DartifactId=ojdbc6 \ -Dversion=10.2.0.3.0 -Dpackaging=jar -Dfile=ojdbc6.jar -DgeneratePom=true

When you want to add a dependency which is not stored in maven repositories to your project this is the way!! You can manually download it and include inside the project and refer it from the pom.xml through a relative path. This example assumes that you have downloaded and stored the jar inside ${project}/src/test/resources/lib.  <dependency> <groupId>ojdbc</groupId> <artifactId>ojdbc6</artifactId> <scope>system</scope> <version>6</version> <systemPath>${basedir}/src/test/resources/lib/ojdbc6.jar</systemPath> </dependency> Here we must specify the scope of the dependency  as 'system'. There is another way which is to manually install the maven dependency to your local repository. You can find out how from here .

To return multiple records we need a REF CURSOR type variable to assign each record. The following is a script which return a REF CURSOR  as OUT parameter. --OracleStroredProc.sql CREATE OR REPLACE PACKAGE Types AS   TYPE cursor_type IS REF CURSOR; END Types; / ------- CREATE OR REPLACE PROCEDURE getEmployeeInfo(p_recordset1 OUT  Types.cursor_type) AS BEGIN     OPEN p_recordset1 FOR     SELECT empNumber, empName, phone, address FROM Employees;     END; / We can run the above script in SQLPLUS as below. SQL> START OracleStroredProc.sql So procedure will be created by now. To call the procedure we have to create a variable of type REFCURSOR and pass it as a parameter to procedure call. Then we can print the variable to see the result. SQL> var a REFCURSOR; SQL> call getEmployeeInfo(:a); Call completed. SQL> print :a;

When you execute a PL/SQL script through sqlplus, if it returns a number at each line you press enter for a new line, it is beacuse you have forgot to include '/' end of the script file for execute. ex: SQL> OracleScript.sql        > 34        > 35 So at this situation just enter '/'. Script will execute. SQL> OracleScript.sql        > 34 / If you don't want to manually enter '/' here, place a '/' end of the script file. The script in here has a '/' end of the file which tells to execute it.

Oracle accepts date in the default format of YYYY-MON-DD . Here month is accepted as three characters of month name. Ex: January-JAN, February: FEB, etc Now before executing a bulk records to a table with a required date format such as YYYY-MM-DD , we can alter the session to accept date in that format from the following query. SQL> alter session set NLS_DATE_FORMAT='YYYY-MM-DD'; Now we can insert records with date represented in YYYY-MM-DD format.

Here we have to drop the user who is the owner of the schema objects with CASCADE option which will result in droping user with the all objects created by that user. SQL> Drop user username CASCADE;

This script will run a query to count the number of users with a specified user name and if the count!=0 then drop user query is executed. DECLARE     u_count number;     user_name VARCHAR2 (50);     BEGIN         u_count :=0;         user_name :='datauser';                     SELECT COUNT (1) INTO u_count FROM dba_users WHERE username = UPPER (user_name);              IF u_count != 0              THEN                  EXECUTE IMMEDIATE ('DROP USER '||user_name||' CASCADE');               END IF;               u_count := 0...
