When the user is loading a record with values and leaves this cell empty. Theory and Concept Practical 3 Objective:. A multicolumn primary key is called composite primary key.

Primary key as a table constraint Create table tablename columnname datatype size. 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.

The data type of the default value should match the data type of the column Syntax: Create table tablename columnname datatype size default value. To Implement the restrictions on the table. Column of any data types may contain null values unless the column was defined as not null when the table was created Syntax: Create table tablename columnname data type size not null …… Primary Key: Column Level Constraints: If the constraints are defined along with the column definition.

Foreign key as a column constraint Syntax: Create table table name columnname datatype size references another table name. Foreign Key Concept: Foreign key represents relationship between tables.

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.

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. Ip may C 96 feb F Y feb.

F 96 apr F Y apr. Insert the following data into their respective tables using insert statement: C may may F N F 96 may P N Ip 96 jan P N jan. Theory and Concept Practical.

Oracle not allow constraints defined using the alter table. To Implement the structure of the table Modifying the Structure of Tables. 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. Cartesian product followed by selection Select B.

Tables are joined on column that have dame data type and data with in tables. Select B. Cartesian product: Cartesian product of tables specified in the FROM clause 2. To achieve this we have to join tables. 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.

Find the date. Client No and salesman No. Find the order No.. Find out the product and their quantities that will have do delivered. Answer the following Queries: To implement the concept of grouping of Data. Tuples with the same value on all attributes in the group by clause are placed in one group. At times it is useful to state a condition that applies to groups rather than to tuples. This condition does not apply to a single tuple.

Grouping Data From Tables: There are circumstances where we would like to apply the aggregate function not only to a single set of tuples. For example we might be interested in only those branches where the average account balance is more than To express such Questionry. The attribute or attributes given in the group by clause are used to form group. SQL applies predicates in the having may be used. Display the month and Date when the order must be delivered.

To insert records in the target table. The statement containing a subQuery called a parent statement. The final output of union clause will be Output: Intersect and Minus Clause: Union Clause: The user can put together multiple Queries and combine their output using the union clause. To implement the concept of SubQueries. The rows returned by the subQuery are used by the following statement. It also termed as nested Query. To update records in the target table. The union clause merges the output of two or more Queries into a single set of rows and column.

Using the Union. Intersect Clause: The use can put together multiple Queries and their output using the interest clause. Find the customer name. Assignment NO. Find the client names who have placed order before the month of may Select all the clients and the salesman in the city of Bombay.

Creation of Views: Creating an Index for a table: Composite Index: This allows the programmer to develop a method via which we can display predetermined data to users according to our desire.

Simplifies Queries. An index is an ordered list of content of a column or group of columns in a table. Hence there is no duplication of data. Physical data is how this data is actually placed in our database. Dropping Indexes: When multiple table columns are included in the index it is called composite index. Views are masks placed upon tables. Provides data security. Assignment No 8 Objective: Answer the following Questions Q1.
