Libraries.Data.Database.DatabaseTypeConstants Documentation
This is a shared class containing the supported type constants for use in the Database Library. These names correspond to the constants in Java's JDBC. The names have been changed and the system can detect how everything maps to Quorum.
Inherits from: Libraries.Language.Object
Summary
Variable Summary Table
| Variables | Description |
|---|---|
| integer TIME | This returns true if the type maps to the Quorum Text type. |
| integer TEXT | VARCH |
| integer INTEGER32 | This returns whether or not the value is an 8-bit, 16-bit, or 32-bit integer. For 64-bit integers, this does not count. |
| integer NUMBER_EXACT_PRECISION | NUMERIC: Must have number of digits (precision) and scale (digits after the decimal poin |
| integer INTEGER16 | SMALLI |
| integer UNDEFINED | NU |
| integer TIMESTAMP | This action returns true if the type is a Date, Time, or a Timestamp. In practice text can be used and will be parsed by the system but Quorum has DateTime calss that will handle getting times and using them in a database easier. |
| integer NUMBER_EXTRA_PRECISION | DECIMAL: Must have at least the number of digits (precision) and scale (digits after the decimal poin |
| integer NUMBER32 | RE |
| integer NUMBER64 | DOUB |
| integer DATE | This returns true if the type maps to the Quorum Text type. |
| integer INTEGER64 | BIGI |
| integer BYTE_FIXED_SIZE | BINA |
| integer BIT | If the value given is of Type BIT this will return true |
| integer BYTE | VARBINA |
| integer NUMBER | This returns true if the type constant maps to a number |
| integer TEXT_FIXED_SIZE | CHAR: A text value of a fixed length, up to 254 in most implementatio |
| integer INTEGER | SMALLI |
| integer INTEGER8 | TINYI |

| Actions | Description |
|---|---|
| Compare(Libraries.Language.Object object) | This action compares two object hash codes and returns an integer. |
| Equals(Libraries.Language.Object object) | This action determines if two objects are equal based on their hash code values. |
| GetHashCode() | This action gets the hash code for an object. |
| IsBoolean(integer value) | If the value given is of Type BIT this will return true |
| IsByteArray(integer value) | Returns true if the type is a Byte Array. |
| IsDateTime(integer value) | This action returns true if the type is a Date, Time, or a Timestamp. |
| IsInteger(integer value) | This returns whether or not the value is an 8-bit, 16-bit, or 32-bit integer. |
| IsInteger64(integer value) | This returns true if the value is a 64-bit Integer. |
| IsNumber(integer value) | This returns true if the type constant maps to a number |
| IsText(integer value) | This returns true if the type maps to the Quorum Text type. |
| IsUndefined(integer value) | in SQL there can be columns with a NULL value and this maps to Quorum's undefined. |
Actions Documentation
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.
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.
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.
IsBoolean(integer value)
If the value given is of Type BIT this will return true
Parameters
Return
boolean:
IsByteArray(integer value)
Returns true if the type is a Byte Array. A byte array is a string of binary characters. It is similar to VARCHAR and text but instead of a string of characters it is a string of binary data.
Parameters
Return
boolean:
IsDateTime(integer value)
This action returns true if the type is a Date, Time, or a Timestamp. In practice text can be used and will be parsed by the system but Quorum has DateTime calss that will handle getting times and using them in a database easier.
Parameters
Return
boolean:
IsInteger(integer value)
This returns whether or not the value is an 8-bit, 16-bit, or 32-bit integer. For 64-bit integers, this does not count.
Parameters
Return
boolean:
IsInteger64(integer value)
This returns true if the value is a 64-bit Integer. In Quorum this would map to the BigInteger Class,
Parameters
Return
boolean:
IsNumber(integer value)
This returns true if the type constant maps to a number
Parameters
Return
boolean:
IsText(integer value)
This returns true if the type maps to the Quorum Text type.
Parameters
Return
boolean:
IsUndefined(integer value)
in SQL there can be columns with a NULL value and this maps to Quorum's undefined.
Parameters
Return
boolean:
