24.24 The INFORMATION_SCHEMA TABLES Table The TABLES table provides information about tables in databases. Notes: Refer to SHOW TABLE STATUS for field descriptions. TABLE_SCHEMA and TABLE_NAME are a single field in a SHOW display, for example Table_in_db1. TABLE_TYPE should be BASE TABLE or VIEW. The TABLES table does not list TEMPORARY tables. For partitioned tables, the ENGINE column shows the name of the storage engine used by all partitions. The TABLE_ROWS column is NULL if the table is in the INFORMATION_SCHEMA database. For InnoDB tables, the row count is only a rough estimate used in SQL optimization.

Join (SQL) A SQL join clause combines columns from one or more tables in a relational database. It creates a set that can be saved as a table or used as it is. A JOIN is a means for combining columns from one (self-table) or more tables by using values common to each. ANSI-standard SQL specifies five types of JOIN: INNER, LEFT OUTER, RIGHT OUTER, FULL OUTER and CROSS. As a special case, a table (base table, view, or joined table) can JOIN to itself in a self-join.

- Table. A table is a data structure that organizes information into rows and columns. It can be used to both store and display data in a structured format. For example, databases store data in tables so that information can be quickly accessed from specific rows.ebsites often use tables to display data in a structured format. In fact, HTML has a tag, as well as (table row) and (table data) tags for specifying rows and columns. Since many tables use the top row for header information, HTML also supports a tag used to define the cells in the header row.

- Well, the straight forward idea is that a column is the vertical part of a matrix and a row is the horizontal part. It's very common that a row is a single element of your data and a column a feature/attribute of your element. It's simple, in an excel sheet on left side of your screen you will see verticle numbers 1,2,3 and so on that are rows and on the top of the screen you will see horizontal A,B,C and so on these are columns.

Table (database) It consists of fields (columns), and rows. In relational databases and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect.he data in a table does not have to be physically stored in the database. Views also function as relational tables, but their data are calculated at query time. External tables (in Informix or Oracle, for example) store data outside standard database structures but accessible to database commands.
