First we need to open a connection to a database by providing the FairCom Database Engine with a user name, password and the database name.
Below is the code for Initialize():
/*
* Initialize()
*
* Perform the minimum requirement of logging onto the c-tree Server
*/
void Initialize(void)
{
RETCODE rc;
printf("INIT\n");
/* allocate environment handle */
if ((rc = SQLAllocEnv(&hEnv)) != SQL_SUCCESS)
Handle_Error(0, NULL, "SQLAllocEnv()");
/* allocate connection handle */
if ((rc = SQLAllocConnect(hEnv, &hDbc)) != SQL_SUCCESS)
Handle_Error(SQL_HANDLE_ENV, hEnv, "SQLAllocConnect()");
/* connect to server */
printf("\tLogon to server...\n");
if ((rc = SQLConnect(hDbc, MY_DSN, SQL_NTS, "admin", SQL_NTS, "ADMIN", SQL_NTS)) != SQL_SUCCESS)
Handle_Error(SQL_HANDLE_DBC, hDbc, "SQLConnect()");
/* allocate statement handle */
if ((rc = SQLAllocHandle(SQL_HANDLE_STMT, hDbc, &hStmt)) != SQL_SUCCESS)
Handle_Error(SQL_HANDLE_DBC, hDbc, "SQLAllocHandle(SQL_HANDLE_STMT)");
}
