例題

The following method adds three rows from data in two arrays (arID and arEmployeeName) into the Employee table:

 vattrVal:=SQL_CONCUR_ROWVER

 $result:=ODBC_SQLSetStmtAttr($statementID;SQL_ATTR_CONCURRENCY;->vattrVal)

 vattrVal:=SQL_CURSOR_KEYSET_DRIVEN

 $result:=ODBC_SQLSetStmtAttr($statementID;SQL_ATTR_CURSOR_TYPE;->vattrVal)

 vattrVal:=3&NBSP;&NBSP; ` Size of the arrays that contain our values below

 $result:=ODBC_SQLSetStmtAttr($statementID;SQL_ATTR_ROW_ARRAY_SIZE;->vattrVal)

 $result:=ODBC_SQLSetStmtAttr($statementID;SQL_ATTR_ROW_STATUS_PTR;->arStatus;vIndic)

 vattrVal:=SQL_UB_VARIABLE

 $result:=ODBC_SQLSetStmtAttr($statementID;SQL_USE_BOOKMARKS;->vattrVal)

  `Use variable length bookmark

 $result:=ODBC_SQLPrepare($statementID;"SELECT * FROM Employee")&NBSP;&NBSP; `Define which table

 $result:=ODBC_SQLExecute($statementID)

 $result:=ODBC_SQLBindCol($statementID;1;->arID)&NBSP;&NBSP; `Bind the columns to arrays

 $result:=ODBC_SQLBindCol($statementID;2;->arEmployeeName)

 

 arID{1}:=1006

 arID{2}:=1007

 arID{3}:=1008

 

 arEmployeeName{1}:="John Smith"

 arEmployeeName{2}:="Betty Jones"

 arEmployeeName{3}:="Sally Peters"

 

 $result:=ODBC_SQLBulkOperations($statementID;4)&NBSP;&NBSP; `SQL_ADD

 

 $result:=ODBC_SQLRowCount($statementID;vRowCount)
