Insert into specific table name(colm 1, colm 2, ……colm N) values(col value1, colm value 2,….colm value 3) When we need to insert the records into the table, we must require the table name, column name, and values for a column. By using this command, we can insert the different records into the specified table that we want. This is the second query, or we can say that command in PL/SQL. The final output of the above statement we illustrated by using the below screenshot is as follows. Inside the bracket, we can write different column names as per our requirement with different data types as shown.Ĭreate table studentA(stud_id number(10) not null, stud_name varchar2(30) not null, stud_city varchar2(30)) īy using create table statement, we created a new table name student A, with different attributes and different data types.

In the above syntax, we use create table statement to create a new table here, the specified table name means the actual table name that we need to create. Unique, check, main key, foreign key, and other restrictions are among the others.Ĭreate table specified table name (required colm name 1specify data type(size), required colm name 2specify data type(size),….required colm name N specify data type(size)) An error will occur if any value attempts to assign a null value. Not null ensures that the variable has a value at all times.

Constants are used to ensure that a value does not change after it is given for the first time. Constant and non-null constraints are the most often utilized constraints. A constraint is a condition that needs to be applied to a certain variable.

Variables declared in any code block can be subjected to constraints. Hadoop, Data Science, Statistics & others 1.
