我創建使用JCO，SAP UTIL用於例如下面的代碼查詢：或多個運營商SAP的Java
public static void TEST() throws JCoException {
JCoDestination destination;
JCoRepository sapRepository;
destination = JCoDestinationManager.getDestination(ABAP_AS);
JCoDestinationManager.getDestination(ABAP_AS);
System.out.println("Attributes:");
System.out.println(destination.getAttributes());
System.out.println();
try {
JCoContext.begin(destination);
sapRepository = destination.getRepository();
if (sapRepository == null) {
System.out.println("Couldn't get repository!");
System.exit(0);
}
JCoFunctionTemplate functionTemplate = sapRepository.getFunctionTemplate("EM_GET_NUMBER_OF_ENTRIES");
JCoFunction function = functionTemplate.getFunction();
JCoTable itTable = function.getTableParameterList().getTable("IT_TABLES");
itTable.appendRow();
itTable.setValue("TABNAME", "USR02");
// JCoTable returnOptions_ = function.getTableParameterList().getTable("OPTIONS");
// returnOptions_.appendRow();
//// //returnOptions.setValue("TEXT", "MODDA GE '20140908' AND MODTI GT '000000'");
// returnOptions_.setValue("TEXT", "BNAME EQ 'USER'");
function.execute(destination);
System.out.println(function.getTableParameterList().getTable("IT_TABLES").getInt("TABROWS"));
JCoFunctionTemplate template2 = sapRepository.getFunctionTemplate("RFC_READ_TABLE");
System.out.println("Getting template");
JCoFunction function2 = template2.getFunction();
function2.getImportParameterList().setValue("QUERY_TABLE", "USR02");
function2.getImportParameterList().setValue("DELIMITER", ",");
function2.getImportParameterList().setValue("ROWCOUNT",5);
function2.getImportParameterList().setValue("ROWSKIPS",5);
System.out.println("Setting OPTIONS");
// Date date = new Date(1410152400000L);
SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMddHHmmss");
// String dateString = formatter.format(date);
// String dt = dateString.substring(0, 8);
// String tm = dateString.substring(8);
// System.out.println("dt > " + dt + ", tm > " + tm);
JCoTable returnOptions = function2.getTableParameterList().getTable("OPTIONS");
returnOptions.appendRow();
//returnOptions.setValue("TEXT", "MODDA GE '20140908' AND MODTI GT '000000'");
returnOptions.setValue("TEXT", "BNAME LIKE 'S%'");
// returnOptions.appendRow();
// returnOptions.setValue("TEXT", "AND TYPE = 'DN'");
System.out.println("Setting FIELDS");
JCoTable returnFields = function2.getTableParameterList().getTable("FIELDS");
returnFields.appendRow();
returnFields.setValue("FIELDNAME", "BNAME");
returnFields.appendRow();
returnFields.setValue("FIELDNAME", "GLTGB");
returnFields.appendRow();
returnFields.setValue("FIELDNAME", "CLASS");
// returnFields.appendRow();
function2.execute(destination);
// JCoTable jcoTablef = function2.getTableParameterList().getTable("FIELDS");
JCoTable jcoTabled = function2.getTableParameterList().getTable("DATA");
int icodeOffSet = 0;
int icodeLength = 0;
int numRows = jcoTabled.getNumRows();
System.out.println("numRows > " + numRows);
for(int i=0; i<numRows; i++) {
jcoTabled.setRow(i);
System.out.println(jcoTabled.getRow());
String BNAME = "BNAE:" + jcoTabled.getString(0);
// String GLTGB = "GLTGB:" + jcoTabled.getString(2);
// String cls = "GLTGB:" + jcoTabled.getString(3);
System.out.println(BNAME + "...");
}
} catch (Exception e) {
e.printStackTrace();
System.out.println("ERROR: " + e.getMessage());
} finally {
JCoContext.end(destination);
}
}
static void createDestinationDataFile(String destinationName, Properties connectProperties)
{
File destCfg = new File(destinationName+".jcoDestination");
try
{
FileOutputStream fos = new FileOutputStream(destCfg, false);
connectProperties.store(fos, "for tests only !");
fos.close();
}
catch (Exception e)
{
throw new RuntimeException("Unable to create the destination files", e);
}
}
上面的代碼工作良好，當我使用的EQ操作。 然而，當我使用IN操作符：
BNAME IN ('USER1','USER','USER3')
或
BNAME EQ 'USER1' OR BNAME EQ 'USER' OR BNAME EQ 'USER3'
它拋出一個異常：Unexpected dynamic condition
在那裏的條件大小是否有限制？由於我在IN條件下有22個字段，每個值的大小都是10？
