Superclass: Sequel::Database

Public Instance Aliases

execute_ddl -> execute

Attributes

columns [W]

Set the columns to set in the dataset when the dataset fetches rows. Argument types supported:

nil

Set no columns

Array of Symbols

Used for all datasets

Array (otherwise)

First retrieval gets the first value in the array, second gets the second value, etc.

Proc

Called with the select SQL query, uses the value returned, which should be an array of symbols
fetch [W]

Set the hashes to yield by execute when retrieving rows. Argument types supported:

nil

Yield no rows

Hash

Always yield a single row with this hash

Array of Hashes

Yield separately for each hash in this array

Array (otherwise)

First retrieval gets the first value in the array, second gets the second value, etc.

Proc

Called with the select SQL query, uses the value returned, which should be a hash or array of hashes.

Class

Should be an Exception subclass, will create a new instance an raise it wrapped in a DatabaseError.
numrows [W]

Set the number of rows to return from update or delete. Argument types supported:

nil

Return 0 for all updates and deletes

Integer

Used for all updates and deletes

Array

First update/delete gets the first value in the array, second gets the second value, etc.

Proc

Called with the update/delete SQL query, uses the value returned.

Class

Should be an Exception subclass, will create a new instance an raise it wrapped in a DatabaseError.
server_version [RW]

Mock the server version, useful when using the shared adapters

Public Instance methods

autoid=(v)

Set the autogenerated primary key integer to be returned when running an insert query. Argument types supported:

nil

Return nil for all inserts

Integer

Starting integer for next insert, with futher inserts getting an incremented value

Array

First insert gets the first value in the array, second gets the second value, etc.

Proc

Called with the insert SQL query, uses the value returned

Class

Should be an Exception subclass, will create a new instance an raise it wrapped in a DatabaseError.
