class TSQLServer: public TObject


Abstract base class defining interface to a SQL server.

To open a connection to a server use the static method Connect().
The db argument of Connect() is of the form:
<dbms>://<host>[:<port>][/<database>], e.g.
mysql://, oracle://, ...
Depending on the <dbms> specified an appropriate plugin library
will be loaded which will provide the real interface.

Related classes are TSQLResult and TSQLRow.

Function documentation

TSQLServer * Connect(const char* db, const char* uid, const char* pw)
 The db should be of the form:  <dbms>://<host>[:<port>][/<database>],
 e.g.:  mysql://, oracle://,
 pgsql://... or sapdb://...
 The uid is the username and pw the password that should be used for
 the connection. Depending on the <dbms> the shared library (plugin)
 for the selected system will be loaded. When the connection could not
 be opened 0 is returned.
Bool_t Exec(const char* sql)
 Execute sql query.
 Usefull for commands like DROP TABLE or INSERT, where result set
 is not interested. Return kTRUE if no error
Int_t GetErrorCode()
 returns error code of last operation
 if res==0, no error
 Each specific implementation of TSQLServer provides its own error coding
const char* GetErrorMsg()
 returns error message of last operation
 if no errors, return 0
 Each specific implementation of TSQLServer provides its own error messages
void ClearError()
 reset error fields
void SetError(Int_t code, const char* msg, const char* method = 0)
 set new values for error fields
 if method is specified, displays error message
Bool_t StartTransaction()
 submit "START TRANSACTION" query to database
 return kTRUE, if succesfull
Bool_t Commit()
 submit "COMMIT" query to database
 return kTRUE, if succesfull
Bool_t Rollback()
 submit "ROLLBACK" query to database
 return kTRUE, if succesfull
TList* GetTablesList(const char* wild = 0)
 Return list of user tables
 Parameter wild specifies wildcard for table names.
 It either contains exact table name to verify that table is exists or
 wildcard with "%" (any number of symbols) and "_" (exactly one symbol).
 Example of vaild wildcards: "%", "%name","___user__".
 If wild=="", list of all available tables will be produced.
 List contain just tables names in the TObjString.
 List must be deleted by the user.
 Example code of method usage:

 TList* lst = serv->GetTablesList();
 TIter next(lst);
 TObject* obj;
 while (obj = next())
   cout << "Table: " << obj->GetName() << endl;
 delete lst;
Bool_t HasTable(const char* tablename)
 Tests if table of that name exists in database
 Return kTRUE, if table exists
TSQLTableInfo* GetTableInfo(const char* tablename)
 Producec TSQLTableInfo object, which contain info about
 table itself and each table column
 Object must be deleted by user.
