(Daniel Campos <danielcampos@netcourrier.com> ) - All float values has been replace
|
|
by double values, as some extra wrong decimals were added in conversions from sql data
|
|
types to Gambas data types.
|
|
|
|
Uses the STL and requires the sqliteclient library. Currently tested with
|
|
SQLite 2.8.13. from www.sqlite.org
|
|
|
|
sqlite is typeless...although in the create you can specify type details (these are
|
|
just comments!). These types have been defined to map to gambas, those not defined
|
|
will default to string.
|
|
|
|
Database/Gambas Type : ft_String/ GB_T_STRING
|
|
DDL Value : BLOB, CHAR(, CLOB, TEXT, VARCHAR, ENUM, SET, YEAR, Non specified
|
|
|
|
Database/Gambas Type : ft_Boolean/ GB_T_BOOLEAN
|
|
DDL Value : CHAR, TINYINT, INT1, BOOL
|
|
|
|
Database Type/Gambas : ft_Short/ GB_T_INTEGER
|
|
DDL Value : SMALLINT, INT2, MEDIUMINT
|
|
|
|
Database/Gambas Type : ft_LongDouble/ GB_T_FLOAT
|
|
DDL Value : BIGINT, INT8
|
|
|
|
Database/Gambas Type : ft_Long/ GB_T_INTEGER
|
|
DDL Value : INTEGER, INT, INT4
|
|
|
|
Database/Gambas Type : ft_Float/GB_T_FLOAT
|
|
DDL Value : DECIMAL, NUMERIC, REAL, FLOAT, FLOAT8, FLOAT4
|
|
|
|
Database/Gambas Type : ft_Date/GB_T_DATE
|
|
DDL Value : TIMESTAMP, DATETIME, DATE, TIME
|
|
|
|
Database/Gambas Type : ft_Double/GB_T_FLOAT
|
|
DDL Value : DOUBLE

Thanks go to Leo Seib for his SQLiteDataset library ( sqlitedataset.sourceforge.net)
|
|
which has been the base for my hacking.
|
|
|
|
The order for locating database files is:
|
|
1) If database is fullpath qualified
|
|
2) If Host is specified as a valid path
|
|
3) If set, GAMBAS_SQLITE_DBHOME variable
|
|
4) Current working directory.
|
|
|
|
The driver will look for databases in the current working directory unless the environment
|
|
variable GAMBAS_SQLITE_DBHOME is set.
|
|
|
|
There is no concept of users within sqlite. Access is controlled by file permissions
|
|
on the database file.
|
|
|
|
Creates database /tmp/sqlite.db by default. For the gambas-database-manager this will
|
|
allow functionality.
|
|
|
|
Sqlite is not case sensative on table or field names. The implementation for Gambas is.
|
|
|
|
Database :memory: will load only in memory
