The easiest way to find all tables in SQL is to query the INFORMATION_SCHEMA views. You do this by specifying the information schema, then the “tables” view. Here's an example. SELECT table_name, table_schema, table_type FROM information_schema.
The following query will show all tables in a MySQL database: SHOW TABLES; To see all the tables, you can run this statement from MySQL Command Line Client, MySQL Shell, as well as from any GUI tool that supports SQL—for example, dbForge Studio for MySQL.
SELECT table_name FROM all_tables WHERE owner = <'schema_name'>; Replace <`schema_name`> with the name of the schema you want to see the tables for. This query will return a list of all tables in the specified schema.
Right-click the Products table in SQL Server Object Explorer, and select View Data. The Data Editor launches. Notice the rows we added to the table in previous procedures. Right-click the Fruits table in SQL Server Object Explorer, and select View Data.
Query: SELECT owner, table_name FROM all_tables; This query returns the following list of tables that contain all the tables that the user has access to in the entire database.
To open explorer go to Tools menu and choose Show Database Explorer. Explorer lists all objects in the database. You can find for specific table or object using quick filter at the top.
This can be achieved by using the following query. SELECT table_schema, SUM(row_count) AS total_rows FROM ( SELECT table_schema, count_rows_of_table(table_schema, table_name) AS row_count FROM information_schema.
In SQL server, the system stored procedure “sp_helpindex” is used to retrieve the information about the indexes that have been defined on a table. It returns the result as a table that contains detailed information about each index, including the name, type, and columns.
The number of tables in a database is limited only by the number of objects allowed in a database (2,147,483,647). A standard user-defined table can have up to 1,024 columns. The number of rows in the table is limited only by the storage capacity of the server.
Because you don't have at least READ or SELECT privs on those tables. For 'normal' (non-DBA) users, when we expand the 'Other Users' node, and go into another schema, and list tables from there – we are querying the ALL_OBJECTS views. These views list things in the database that you have the security rights to see.
In SQL, to fetch data from multiple tables, the join operator is used. The join operator adds or removes rows in the virtual table that is used by SQL server to process data before the other steps of the query consume the data.
SELECT TABLE_NAME FROM USER_TABLES will provide you with listing of tables in a particular schema. SELECT TABLE_NAME, OWNER FROM ALL_TABLES will provide you with listing of all tables for all schemas in the DB for which you have at least select privilege.
The ALL_TABLES view describes all tables accessible to the current user. The column names and data types are the same as the Oracle Database. TimesTen returns NULL for some columns that are not supported in TimesTen. You should ignore such columns.
You can get the MySQL table columns data type with the help of “information_schema. columns”. SELECT DATA_TYPE from INFORMATION_SCHEMA. COLUMNS where table_schema = 'yourDatabaseName' and table_name = 'yourTableName'.
SELECT query is used to retrieve data from a table. It is the most used SQL query. We can retrieve complete table data, or partial by specifying conditions using the WHERE clause.
