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: primary key is one or more columns is a table used to uniquely identity each row in the table. 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 constraints can either be placed at column level or at the table level. Syntax: primary key as a column constraint Create table tablename columnname datatype size primary key. Data constraints: Besides the cell name. Primary key values must not be null and must be unique across the column. A foreign key must have corresponding primary key value in the primary key table to have meaning. Foreign Key Concept : Foreign key represents relationship between tables.
Foreign key as a table constraint: Syntax : 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. Foreign key as a column constraint Syntax : Create table table name columnname datatype size references another table name.
A foreign key is column whose values are derived from the primary key of the same of some other table. F 96 apr F Y apr. Ip may C 96 feb F Y feb. F 96 may P N Ip 96 jan P N jan. C may may F N To Implement the structure of the table Modifying the Structure of Tables. Alter table command is used to changing the structure of a table. NOTE: Oracle not allow constraints defined using the alter table. The following tasks you can perform through alter table command.
Following command is used for removing or deleting a table. The following examples show the definitions of several integrity constraints. Theory and Concept Practical. Using the alter table clause you cannot perform the following tasks: i change the name of table ii change the name of column iii drop a column iv decrease the size of a table if table data exists. The following examples illustrate the dropping of integrity constraints. Cartesian product of tables specified in the FROM clause 2.
To achieve this we have to join tables. To implement the concept of Joins Joint Multiple Table Equi Join : 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. Tables are joined on column that have dame data type and data with in tables.
Cartesian product:- Consider two table student and course Select B. Select B. Find the date. Client No and salesman No. Find the order No. Find out the product and their quantities that will have do delivered. At times it is useful to state a condition that applies to groups rather than to tuples.
For example we might be interested in only those branches where the average account balance is more than Grouping Data From Tables: There are circumstances where we would like to apply the aggregate function not only to a single set of tuples.
To express such Questionry. The attribute or attributes given in the group by clause are used to form group. This condition does not apply to a single tuple. SQL applies predicates in the having may be used.
Tuples with the same value on all attributes in the group by clause are placed in one group. To implement the concept of grouping of Data. Calculate the average quantity sold for each client that has a maximum order value of Print the description and total quantity sold for each product. Display the order number and day on which clients placed their order Find the value of each product sold. Answer the following Queries: Q1.
Display the month and Date when the order must be delivered. Find out the products which has been sold to Ivan.
The rows returned by the subQuery are used by the following statement. It can be used by the following commands: 1. To insert records in the target table. It also termed as nested Query. The statement containing a subQuery called a parent statement.
To create tables and insert records in this table. 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.
To create view. To update records in the target table. To implement the concept of SubQueries. Intersect Clause: The use can put together multiple Queries and their output using the interest clause. Using the Union. Select all the clients and the salesman in the city of Bombay.
Find the client names who have placed order before the month of may Select the names of persons who are in Mr. Assignment NO. Find the customer name. Views may be created fore the following reasons: 1. An index created on the single column of the table is called simple index. Hence there is no duplication of data. Views are masks placed upon tables. Provides data security. Avoids data redundancy.
An index is an ordered list of content of a column or group of columns in a table. The DBA stores the views as a definition only. Physical data is how this data is actually placed in our database. Can be Queried as a base table itself. To implement the concept of Indexes and views.
When multiple table columns are included in the index it is called composite index. Views:- Logical data is how we want to see the current data in our database. Theory and Concept Practical 8 Objective:. Simplifies Queries. This allows the programmer to develop a method via which we can display predetermined data to users according to our desire.
After the form is created.
Run the form and execute the Questionry. Click Create Relationship. Each block contains items which equal table columns or fields. Start Schema Builder. Scroll through the data and notice that the orders are linked with the customers. To Implement the concept of Forms and reports.
Go to Physical on property pallet. If you have two table joined by a relationship table. Make sure Autojoin Datablocks is checked. Right click on Window1. Go up to Tools — Data Block Wizard. To delete a record. This relationship can be seen if you open schema builder and look at the tables and the relationship between them. Notice that data already exists in this table. Execute the Questionry. If you input a detail. Click on Property Pallet. This says that the parent table.
Highlight Data Blocks in the Object Navigator. To input a mark. These are arranged into records. Theory and Concept Practical 9 Objective:. If there is any problem with integrity. After you make any change. IE — If you have two tables and one relation table such as — Students — Have — Marks The have table would include at least one column.
Records displayed will be 5 and Display Scrollbar will be checked off. Click OK. Run the form. Make the layout tabular. Start Form Builder.
To create a grouped report: 1. Now you can include the remaining fields you left out before. Click next. We will do two sums on some fields. Select Mbillno and include it. A check mark should appear to the left of the field when it is selected. When choosing the layout template. The words Group 2 should appear above it. It is now included in group 1 if the Group 2 is no longer displayed.
Next select Vencompanyname. If the layout is not as you would like. Above it on the right hand side. Select the fields by double clicking them.
Start report builder. The grouping window will now open. Details if other: Thanks for telling us about the problem. Return to Book Page. Get A Copy. More Details Original Title. Other Editions 1.
