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.

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
- Libraries.Language.Object: The object to compare to.
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
- Libraries.Language.Object: The to be compared.
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

integer
Rollback()
SetAutoCommit(boolean commit)
Parameters
