10/4/2023 0 Comments Show database sqlite 3There were initially only a couple of speck orders, however, throughout the long term numerous new highlights have aggregated so today there are more than 60. These “speck orders” are commonly used to change the yield configuration of inquiries, or to execute certain prepackaged inquiry explanations. However, input lines that start with a dab (“.”) are caught and deciphered by the sqlite3 program itself. More often than not, sqlite3 simply peruses lines of info and gives them to the SQLite library for execution. Type in SQL explanations (ended by a semicolon), press “Enter” and the SQL will be executed. On startup, the sqlite3 program will show a short pennant message at that point brief you to enter SQL. In the event that no data set record is indicated on the order line, a transitory information base is made, at that point erased when the “sqlite3” program exits. In the event that the named record doesn’t exist, another information base document with the given name will be made consequently. Start the sqlite3 program by composing “sqlite3” at the order brief, alternatively followed by the name of the record that holds the SQLite database (or ZIP chronicle). This record gives a concise acquaintance on how to utilize the sqlite3 program. The SQLite project gives a basic command-line program named sqlite3 (or sqlite3.exe on Windows) that permits the client to physically enter and execute SQL different statements against SQLite data set or against a ZIP chronicle. Now let’s see how the show table works in SQLite as follows. tables command or by querying data from the sqlite_schema table.Syntax of the show table is very simple and easy, here we just mentioned a dot table that is (.tables). In this tutorial, you have learned how to show all tables in a database using the. Note that SQLite changed the table sqlite_master to sqlite_schema. These tables are the system tables managed internally by SQLite. In this query, we filtered out all tables whose names start with sqlite_ such as sqlite_stat1 and sqlite_sequence tables. WHERE type = 'table' AND name NOT LIKE 'sqlite_%' Code language: SQL (Structured Query Language) ( sql ) The output is as follows: playlist_track tracks Code language: SQL (Structured Query Language) ( sql ) Showing tables using SQL statementĪnother way to list all tables in a database is to query them from the sqlite_schema table. tables '%ck%' Code language: SQL (Structured Query Language) ( sql ) To shows the tables whose name contains the string ck, you use the %ck% pattern as shown in the following command. Here is the output: albums artists Code language: plaintext ( plaintext ) table 'a%' Code language: SQL (Structured Query Language) ( sql ) The pattern must be surrounded by single quotation marks ( ').įor example, to find tables whose names start with the letter ‘a’, you use the following command. The command works the same as LIKE operator. tables pattern Code language: SQL (Structured Query Language) ( sql ) If you want to show tables with the specific name, you can add a matching pattern. The following shows the output: albums employees invoices playlistsĪrtists genres media_types temp.temp_table1Ĭustomers invoice_items playlist_track tracks Code language: SQL (Structured Query Language) ( sql )īecause the schema of temporary tables is temp, the command showed the names of schema and table of the temporary table such as temp.temp_table1. tables Code language: SQL (Structured Query Language) ( sql ) Second, list all tables from the database. See the following example:įirst, create a new temporary table named temp_table1: CREATE TEMPORARY TABLE temp_table1( name TEXT ) Code language: SQL (Structured Query Language) ( sql ) tables command also can be used to show temporary tables. tables command lists all tables in the chinook database albums employees invoices playlistsĬustomers invoice_items playlist_track Code language: SQL (Structured Query Language) ( sql ) tables command: tables Code language: SQL (Structured Query Language) ( sql ) The above statement opened the database named chinook.db that locates in the c:\sqlite\db directory. To show tables in a database using the sqlite command-line shell program, you follow these steps:įirst, open the database that you want to show the tables: sqlite3 c:\sqlite\db\chinook.db Code language: SQL (Structured Query Language) ( sql ) Showing tables using the sqlite command line shell program Summary: in this tutorial, you will learn various ways to show tables from an SQLite database by using the SQLite command-line shell program or by querying data from sqlite_master tables.
