Desc of table in razorsql3/22/2023 RazorSQL is a SQL database query tool, SQL editor, database browser, and administration tool with support for over 40 databases and built in connection capabilities for Access, Cassandra, DB2, Derby, DynamoDB, Firebird, HSQLDB, H2, Informix, Microsoft SQL Server, MariaDB, MongoDB, MySQL, Oracle, Pervasive, PostgreSQL, Redshift, Salesforce, SimpleDB, SQL Anywhere, SQLite, Sybase, and Teradata. Here we also discuss the definition and how to describe the table in oracle? along with different examples and its code implementation.RazorSQL - SQL database query tool, browser, and editor that supports all major databases This is a guide to Oracle Describe Table. Once we have created the object then now we will use the DESCRIBE function to check the structure of the object.Īs we can see in the screenshot of the output, the name of the column along with their data type and size is displayed. Let us now execute the above query in SQL developer and create the object. In this query, we are creating an object with two columns. In this example, we are going to use the Oracle database to check how DESCRIBE function describes an object. Let us execute the query in SQL developer and check the result.Īs we can see in the above screenshot the query returns the structure of each procedure present inside the package 4. After we have created the package let us now use the DESCRIBE function to get the structure of the package. Let us now execute the query and create a package. In this query, we are creating a package with two procedures and each procedure having two arguments. PROCEDURE print_diff(first_number NUMBER, second_number NUMBER) PROCEDURE print_sum(first_number NUMBER, second_number NUMBER) For that, we will create a package with two procedures, and then we will use the describe function to describe the package. In this example, we are going to use the Oracle database to check how the DESCRIBE function describes a stored package. Once we have created the procedure then now we will use the DESCRIBE function to check the structure of the procedure.Īs we can see in the above screenshot the query returns the name of the arguments, the data type of the arguments, and also whether the arguments were IN, OUT, or DEFAULT. Let us now execute the above query in SQL developer and create the procedure. In this procedure, we are calculating the sum of two values and we are using the two arguments as inputs to the procedure. Let us create a procedure.įirst_number NUMBER, second_number NUMBER For that, we will create a procedure with two arguments, and then we will use the describe function to describe the procedure. In this example, we are going to use the Oracle database to check how the DESCRIBE function describes a stored procedure. Describe Function to Describe a Procedure The first column is NOT NULL since we had added a PRIMARY KEY constraint to the column while creating the table. Let us now execute the query in SQL developer and check the result.Īs we can see in the screenshot the output displays the column names, whether the values in the columns can be NULL or NOT NULL, and the data type along with the size of the column. Let us now use the DESCRIBE command to know the structure of the table. In the above query, we are creating the table employee with the employee_id as the primary key and three more columns. Let us prepare a CREATE statement to create a table.ĬREATE table employee(employee_id varchar2(25) PRIMARY KEY,Įmployee_name varchar2(100), city varchar2(20), salary number(5)) For that, we will create a table with a few columns and then we will use the describe function to describe the table. In this example, we are going to use the Oracle database to check how the function describes the table. Now, in this section, we are going to look at a few examples of the describe function to have a better understanding. In the earlier sections, we got to understand the definition, syntax, and working of the DESCRIBE function.
