| - | The CREATE TABLE statement declares the characteristics of the table. At a minimum, each table has a name and instructions for accessing the physical data. Omnidex supports configuration settings for each table, including settings for [[dev:sql:statements:create_table:delimited_files | delimited files]], [[dev:sql:statements:create_table:data_cache | data caches ]] and [[dev:sql:statements:create_table:index_maintenance | index maintenance]]. Omnidex also provides [[dev:sql:statements:create_table:rollup_tables | rollup tables]] which pre-aggregate another table in the database and automatically optimize queries against the table. | + | The CREATE TABLE statement declares the characteristics of the table.

| Like most databases, Omnidex allows indexes to be declared using the CREATE INDEX statement. For convenience, Omnidex also allows indexes to be declared using the CREATE TABLE statement. In most applications, many (if not all) of the columns are indexed with Omnidex, so it is convenient to declare the indexing directly in the table specification. | Like most databases, Omnidex allows indexes to be declared using the CREATE INDEX statement.

| - | Omnidex allows constraints and indexing to be declared alongside each column. With [[dev:sql:statements:create_table:inlining | inlining]], the constraint and indexing specification is provided as each column is declared.
