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` 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`Define which table
 $result:=ODBC_SQLExecute($statementID)
 $result:=ODBC_SQLBindCol($statementID;1;->arID) &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"
