Package

Signature

create-table name description &key database type extra-options

Arguments

`name`⇩	The name of the table.
`description`⇩	The table properties.
`database`⇩	A database.
`type`⇩	A string or the keyword `:support-transactions`, or `nil`.
`extra-options`⇩	A string or `nil`.

Description

The function create-table creates a table called name and defines its columns and other properties with description. The argument description is a list containing lists of attribute-name and type information pairs.

The default value of database is *default-database*.

type and extra-options are treated in a database-type specific way. Currently only database-type :mysql uses these options, as follows.

If type is not supplied, it defaults to the value (if any) of default-table-type that was supplied to connect. If extra-options is not supplied, it defaults to the value (if any) of default-table-extra-options that was supplied to connect.

type, if non-nil, is used as argument to TYPE in the SQL statement:

create table MyTable (column-specs) TYPE = type

except that if type is :support-transactions then create-table will attempt to make tables that support transactions, by using the type innodb.

extra-options (if non-nil) is appended in the end of this SQL statement.

When database-type is not :mysql, type and extra-options are ignored.

Examples

The following code:

(create-table [manager]
  '(([id] (char 10) not-null)
    ([salary] (number 8 2))))

is equivalent to the following SQL:

CREATE TABLE MANAGER
   (ID CHAR(10) NOT NULL,SALARY NUMBER(8,2))
