The PRAGMA table info() function returns a single entry on every field in the table given. You can add the values with the insert command at once, but we have inserted them one by one.Įxample 1: Using PRAGMA table_info() Method to Show the Table’s Structure Then, we have added some values against each field of the table pet by using the SQLite insert command. The pet table fields include pet_id, pet_name, pet_price, pet_gender, and pet_stock with the different data types as per their requirement. We have used below the create command for creating a table and defined a table name as “pet.” We have specified some fields with the data types inside the pet table. To begin, we’ll use the create table command to construct a table. Let’s peek at several alternative ways of describing tables. SQLite Table Creation for Performing the Method That Shows the Structure of the Table Each SQLite database’s schema is kept in a unique “schema table.” The schema is a visual representation of all the database’s records, collections, triggers, and views. This operation represents the selected table however, we must first build the table before using it.Īnother method of showing the table’s structure is by using the SQLite master table is this one. The only distinction is that it provides the virtual table’s hidden column. This method is similar to the previous statement. This command returns a single row from each column in the defined table, similar to the SQL DESCRIBE command. We have shown the syntax of each method through which we can view the structure of the table. In most cases, the table can be described in four ways. In SQLite, the schema command operates as follows.
Let’s have a glance at the description table command in action.
#JANETTER SQLITE HOW TO#
There are numerous methods in SQLite for retrieving data from a table.” How to Display the Structure of a Table Essentially, describing the table implies printing information about each column, such as the column name, data type, and size. schema query is used to define the tables it is a control program, and we must follow specific procedures if we need an effect of the table at that moment. “SQLite provides the user with various tools like the describe command, which allows us to inspect the table’s precise structure.
