Problem Statement: When trying to connect an aspen SQLplus client to an Aspen InfoPlus.21 server, the following error messages may sometimes appear:
Error: Unable to get client user context
Error: Unable to access a secured SQLplus server due to incompatible SQLplus client! | Solution: The problem is that the SQLplus server task is unable to find out who you are logged in as. Usually it relates to Win9x client PC's that do not use secure login or clients that are not on a (trusted) Windows domain. The problem has at its core Windows authentication problems. The SQLplus server task at the In... |

Problem Statement: This Knowledge Base article describes how to construct a loop in Aspen SQLplus which loops through the elements in descending order. For example, instead of looping from 1 to 10 (ascending order), loop in descending order -- from 10 down to 1. | Solution: Below are two Aspen SQLplus code examples which illustrate how to accomplish this:
LOCAL x INTEGER;
LOCAL y INTEGER;
FOR x = 1 to 10 DO
y = 10 - x;
WRITE y;
END
In the above example, the FOR LOOP is still processing in ascending sequence (the x variable). However, the y variable can be used as the descending... |

Solution
In order to successfully reference Microsoft Excel 12.0 Object Library, it is necessary that Microsoft Office 2007 has been installed on the InfoPlus.21 Server as well as the workstation running the Client software.
The reason why it is possible to use the library in Process Explorer but not... |
Problem Statement: Why can't I use the value of a MACRO definition immediately after defining it? | Solution: SQLplus requires a statement between the MACRO definition and its use. This statement can be anything including a null statement (;).
For Example, the following does not work:
MACRO TestMacro='RC345';
'&TestMacro'->Value=10;
The problem is that SQLplus has read the next token after the ; before it has exec... |
Problem Statement: Why does SQLPlus return only 99 columns when using the Cross By query? | Solution: There is a limit on the number of columns in a cross query. The default for this limit is 100 but a different Value can be specified with a FIRST clause after the BY.
Example:
Select ts, max(value) by name first 200 from history
Where name in (select name from ip_analogdef)
Group By ts;

Problem Statement: If an SQLplus client is attempting to connect to an unresponsive or powered down SQLplus server, the client can take a (seemingly) long time to return a no connect error. However, it is possible to minimize the timeout period by adjusting TCP/IP registry settings.
The following Tech Tip provides dire... | Solution: The timeout period for connecting either the Query Writer or Desktop ODBC to an SQLplus server is partially controlled by the registry setting TcpMaxConnectRetransmissions. This parameter specifies the number of times the server will attempt to retransmit a connection acknowledgement before aborting the conne... |
Problem Statement: What Aspen InfoPlus.21 tasks are the ProcedureDef records run on?
Are these records run by a single Aspen InfoPlus.21 task? | Solution: The Aspen SQLplus product uses external TSK_IQ tasks (i.e. tasks that start an occurrence of the C:\Program Files\AspenTech\InfoPlus.21\db21\code\iqtask.exe executable) to run queries and procedures.
Stored Procedures are always executed on the same task as the query that calls them. For example, if a QueryDe... |

Problem Statement: Is it possible to subtract a large number of days from a timestamp value? | Solution: You can subtract (or add) values from a timestamp in SQLplus by subtracting the value in 1/10 second intervals. So to subtract 1 day this would be 1*24*60*600 (1 day * 24 hours * 60 minutes * 600 tenths seconds). For example:
local dayvalue int;
local t1 timestamp;
t1 = '01-Mar-14 10:25:30.1';

Invalid timestamp <timestamp>, check format is YYYY-MM-DD HH:MM:SS and numbers are in range
All of these error messages indicate a problem with... | Solution: Check on the version of Aspen SQLplus used. ISO timestamp formats are only supported in v6.0 and above. A query using ISO timestamp being executed on a pre-v6.0, will result in error messages.
Ensure that Aspen InfoPlus.21 database and the SQL script are configured with the same time setting. To check the tim... |
Problem Statement: The EXECUTE and EXEC commands allow you to execute queries on remote nodes. The remote query appears in single quotes following the EXECUTE or EXEC command. If the remote query is long or is complex, it can be difficult to handle in the Aspen SQLplus query writer.
This | Solution: describes how to work around this problem.Solution
Knowledge base article 138104 describes how to split a long EXECUTE command over several lines.
You can also place the command into a text file and read the query from the file as follows:
1) Save the query in a text file, for example C:\Temp\MyQuery.txt

Problem Statement: When you run a query using the Aspen SQLplus Query writer, the default timeout value for the query is 180 seconds; A however, an external task like TSK_IQ1 executing a query defined by QueryDef or CompQueryDef records, by default has no timeout.A This article explains how to add a timeout parameter t... | Solution: Using the Aspen InfoPlus.21 Manager, modify the command line parameters field for the IQ task (TSK_IQ1, for example) to add the switch /t=nn, where nn is the timeout in seconds.A
This switch sets the timeout for all queries processed by the IQ task.A If other query records require a different timeout value, y... |
