If you input a detail, the foreign key is automatically filled with the value of the current primary key displayed by the customer. To delete a record, you must first delete the details, save the change, then delete the master and save.
After you make any change, save the data. If there is any problem with integrity, the record wont save.

If you have two table joined by a relationship table, the relationship table MUST contain valid data or you will not be able to add data to the detail table. To create a grouped report: 1. Start report builder. Select use the report wizard 3.
Title the report Mainenance Bill and select Group Above and click next. Click on Questionry Builder. Select the fields by double clicking them. A check mark should appear to the left of the field when it is selected. Click Next.
The grouping window will now open. Select Mbillno and include it. Above it on the right hand side, the words Group 1 should appear. Next select Vencompanyname.
The words Group 2 should appear above it. Click on the Vencompanyname you have just selected on the right and drag it up to group 1.

Column Level Constraints: If the constraints are defined along with the column definition, it is called a column level constraint.
Table Level Constraints: If the data constraint attached to a specify cell in a table reference the contents of another cell in the table then the user will have to use table level constraints.
Null Value Concepts: Column of any data types may contain null values unless the column was defined as not null when the table was created. Primary Key: Primary key values must not be null and must be unique across the column. A multicolumn primary key is called composite primary key. Primary key as a table constraint Create table tablename columnname datatype size , columnname datatype size Primary key columnname,columnname ;.
Default value concept: At the line of cell creation a default value can be assigned to it. When the user is loading a record with values and leaves this cell empty, the DBA will automatically load this cell with the default value specified.
The data type of the default value should match the data type of the column. Create table tablename columnname datatype size default value,. Foreign key represents relationship between tables. A foreign key is column whose values are derived from the primary key of the same of some other table.
A foreign key must have corresponding primary key value in the primary key table to have meaning. Foreign key as a column constraint. Create table table name columnname datatype size references another table name ;. Create table name columnname datatype size.
Check Integrity Constraints: Use the check constraints when you need to enforce integrity rules that can be evaluated based on a logical expression following are a few examples of appropriate check constraints.
Using the alter table clause you cannot perform the following tasks:. Oracle not allow constraints defined using the alter table, if the data in the table, violates such constraints. The following examples show the definitions of several integrity constraints. You can drop an integrity constraint if the rule that if enforces is no longer true or if the constraint is no longer needed. The following examples illustrate the dropping of integrity constraints.
Default N. Table Name: Some times we require to treat more than one table as though manipulate data from all the tables as though the tables were not separate object but one single entity. To achieve this we have to join tables. Tables are joined on column that have dame data type and data with in tables.
Cartesian product of tables specified in the FROM clause 2. Cartesian product: Cartesian product followed by selection Select B. Select B. Find out the product which has been sold to Ivan Sayross. Find out the product and their quantities that will have do delivered. Find the products and their quantities for the orders placed by Vandan Saitwal and Ivan Bayross. Find the order No,, Client No and salesman No.
Find the date , 15 days after date. Grouping Data From Tables: There are circumstances where we would like to apply the aggregate function not only to a single set of tuples, but also to a group of sets of tuples, we specify this wish in SQL using the group by clause. The attribute or attributes given in the group by clause are used to form group. Tuples with the same value on all attributes in the group by clause are placed in one group. For example we might be interested in only those branches where the average account balance is more than To express such Questionry, we use the having clause of SQL.
SQL applies predicates in the having may be used. It also termed as nested Query. The statement containing a subQuery called a parent statement. The rows returned by the subQuery are used by the following statement.
It can be used by the following commands: To insert records in the target table. To create tables and insert records in this table.
To update records in the target table. To create view. Using the Union, Intersect and Minus Clause: Union Clause: The user can put together multiple Queries and combine their output using the union clause.
The union clause merges the output of two or more Queries into a single set of rows and column. The final output of union clause will be. Intersect Clause: The use can put together multiple Queries and their output using the interest clause.
The final output of the interest clause will be:. Find the customer name, address, city and pincode for the client who has placed order no 3. Find the client names who have placed order before the month of may Find out if product 1. Select the orders placed by Rahul Desai 7. Select the names of persons who are in Mr. Pradeeps department and who have also worked on an inventory control system. Select all the clients and the salesman in the city of Bombay. Select salesman name in Bombay who has atleast one client located at Bombay Theory and Concept Practical 8.
Indexes- An index is an ordered list of content of a column or group of columns in a table. An index created on the single column of the table is called simple index.

When multiple table columns are included in the index it is called composite index. Creating an Index for a table: Physical data is how this data is actually placed in our database.
Views are masks placed upon tables. This allows the programmer to develop a method via which we can display predetermined data to users according to our desire. Views may be created fore the following reasons:. The DBA stores the views as a definition only. Hence there is no duplication of data. Simplifies Queries. Can be Queried as a base table itself. Provides data security. Avoids data redundancy. Creation of Views: Theory and Concept Practical 9 Objective: The objective of the lab is to create a form using a parent table and a child table to take advantage of the schemas relationships.
Each block contains items which equal table columns or fields. These are arranged into records. Start Schema Builder.
Start Form Builder. After the form is created, click on Window on the Object Navigator to expand it. Right click on Window1. Click on Property Pallet.
Go to Physical on property pallet. Run the form. Execute the Questionry. Notice that data already exists in this table.
Highlight Data Blocks in the Object Navigator. Go up to Tools Data Block Wizard. Click Create Relationship. Click OK. Make sure Autojoin Datablocks is checked. This relationship can be seen if you open schema builder and look at the tables and the relationship between them.
Make the layout tabular. Records displayed will be 5 and Display Scrollbar will be checked off.
Run the form and execute the Questionry. Scroll through the data and notice that the orders are linked with the customers. If you input a detail, the foreign key is automatically filled with the value of the current primary key displayed by the customer.
To delete a record, you must first delete the details, save the change, then delete the master and save. After you make any change, save the data. If there is any problem with integrity, the record wont save. If you have two table joined by a relationship table, the relationship table MUST contain valid data or you will not be able to add data to the detail table. To create a grouped report: Start report builder.
