Public Member Functions

 LiteDb (sqlite3 *con)
bool isClosed ()
void closeDb ()
RLiteMemTable execDirect (IN(RString) sql)
 execute a sql command on a LiteDB The complete result set will be hold in memory

void execute (IN(RString) sql)
 executes a SQL command

void execute (IN(RString) sql, IN(acdk::lang::dmi::RDmiDelegate) delegate)

 creates a prepared statement

void createSqlFunction (IN(RString) function, int args, IN(acdk::lang::dmi::RDmiDelegate) delegate)
 this creates a function can be used inside an SQL Statement.

void acdk::sql::sqlite::LiteDb::createSqlFunction IN(RString function,
int  args,
IN(acdk::lang::dmi::RDmiDelegate delegate
 

this creates a function can be used inside an SQL Statement.

It is similar to stored procedure, but the function itself is not stored within the database, but provided by the application

RLiteMemTable acdk::sql::sqlite::LiteDb::execDirect IN(RString sql  ) 
 

execute a sql command on a LiteDB The complete result set will be hold in memory

void acdk::sql::sqlite::LiteDb::execute IN(RString sql,
IN(acdk::lang::dmi::RDmiDelegate delegate
 

executes a SQL command an calles the delegate for each record set The arguments passed to the delegate are: - LiteDb __db - all fields as String of one record.

  • The delete should return an int. if the return value is != 0 no more records will be fetched. See also samples in  acdk_sql_sqlite.

void acdk::sql::sqlite::LiteDb::execute IN(RString sql  ) 
 

executes a SQL command

int acdk::sql::sqlite::LiteDb::executeUpdate IN(RString cmd  ) 
 

execute update, return the number of changes

sqlite3* acdk::sql::sqlite::LiteDb::getConPtr  )  [inline]
 

RString acdk::sql::sqlite::LiteDb::getVersion  )  [static]
 

return the version string of the sqlite3 c library

bool acdk::sql::sqlite::LiteDb::isClosed  )  [inline]
 

RLiteDb acdk::sql::sqlite::LiteDb::openDb IN(RString fileName  )  [static]
 

RLiteTable acdk::sql::sqlite::LiteDb::prepareStatement IN(RString sql  ) 
 

creates a prepared statement
