Libraries.Data.Database.Strategies.DefaultDatabaseStrategy Documentation

This class implements a DatabaseStrategy and is the default strategy the Database class uses. This class uses a plugin that connects to MySQL servers so if using another system underneath such as PostgreSQL another class needs to be made that implements the actions in DatabaseStrategy.

Commit()

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Connect(Libraries.Data.Database.Connection connection)

Parameters

CreateTable(Libraries.Data.Database.CreateTable creation)

Parameters

CreateView(Libraries.Data.Database.CreateView query)

Parameters

Delete(Libraries.Data.Database.Delete query)

Parameters

Return

integer

DropTable(Libraries.Data.Database.DropTable drop)

Parameters

EditTable(Libraries.Data.Database.EditTable edit)

Parameters

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Find(Libraries.Data.Database.Find query)

Parameters

Return

Libraries.Data.Database.QueryResult

GetAutoCommit()

Return

boolean

GetDatabaseMetaData()

Return

Libraries.Data.Database.DatabaseMetaData

GetHashCode()

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

Return

integer: The integer hash code of the object.

Insert(Libraries.Data.Database.Insert query)

Parameters

Return

integer

Rollback()

SetAutoCommit(boolean commit)

Parameters

Update(Libraries.Data.Database.Update query)

Parameters

Return

integer
