PostgreSQL CallableStatement:偏移量6处的函数或过程转义语法格式错误
Java应用程序使用CallableStatement调用Postgres存储函数时出错。错误如下:PostgreSQL CallableStatement:偏移量6处的函数或过程转义语法格式错误,postgresql,jdbc,callable-statement,Postgresql,Jdbc,Callable Statement,Java应用程序使用CallableStatement调用Postgres存储函数时出错。错误如下: org.postgresql.util.PSQLException: Malformed function or procedure escape syntax at offset 6. at org.postgresql.jdbc2.AbstractJdbc2Statement.modifyJdbcCall(AbstractJdbc2Statement.java:2390) a

进行调用的Java方法:
public ArrayList<UserRoleDocumentPermissionDao> getUserRoleDocumentPermission (int userRoleId){
ArrayList<UserRoleDocumentPermissionDao> result = new ArrayList<UserRoleDocumentPermissionDao>();
try{
cstmt = myConnection.prepareCall("{ ? = \"user_role_document_permission_select_all_per_user_role\"(?)}");
cstmt.registerOutParameter(1, Types.OTHER);
cstmt.setInt(2, userRoleId);
cstmt.execute();
rs = (ResultSet) cstmt.getObject(1);
ResultSetMetaData rsmd = rs.getMetaData();
int columnCount = rsmd.getColumnCount();
UserRoleDocumentPermissionDao udao;
while (rs.next()){
udao = new UserRoleDocumentPermissionDao();
for (int i = 1; i <= columnCount; i++){
if (i == 1){ // document name
udao.setDocumentName(rs.getString(i));
} else if (i == 2){ // view
udao.setViewing(rs.getBoolean(i));
} else if (i == 3){ // process
udao.setProcessing(rs.getBoolean(i));
} else if (i == 4){ // edit
udao.setEditing(rs.getBoolean(i));
} else if (i == 5){ // update
udao.setUpdating(rs.getBoolean(i));
} else if (i == 6){ // userRoleId
udao.setUserRoleId(rs.getInt(i));
} else if (i == 7){ // documentId
udao.setDocumentId(rs.getLong(i));
}
}
result.add(udao);
}
} catch (SQLException e){
System.out.println("SQL Exception: ");
e.printStackTrace();
} finally {
closeConnection();
}
return result;
}
道:
public class UserRoleDocumentPermissionDao {
private String documentName;
private boolean viewing;
private boolean processing;
private boolean editing;
private boolean updating;
private int userRoleId;
private Long documentId;
public UserRoleDocumentPermissionDao(){}
public UserRoleDocumentPermissionDao(String docName, boolean view,
boolean process, boolean edit, boolean update, int userRoleIdin, Long docId){
this.documentName = docName;
this.viewing = view;
this.processing = process;
this.editing = edit;
this.updating = update;
this.userRoleId = userRoleIdin;
this.documentId = docId;
}
/////// getters and setters
我不知道为什么会这样。我已经能够成功地从返回refcursor的Postgres存储函数中获得结果,并且我似乎无法找出该函数/函数调用与此函数/函数调用之间的任何区别
任何想法都将不胜感激您忘记了
