The HISTORY table in SQLplus uses the RHIS21DATA call... |
Problem Statement: It is sometimes necessary to determine via SQLplus which record has a particular record ID, or RECID. RECIDs are used throughout InfoPlus.21 & the associated API calls. | Solution: The easiest way to construct such a query is to draw on the all_records table for the RECID. The all_records table contains a list of all records which exist in the InfoPlus.21 database. Using a query which incorporates this table works because every record in the database has a RECID. Indirection must be use... |
Problem Statement: If you want to read the lines from a text file that has more than 80 characters on one line, and you use the following Statement
Select line from <TEXTFILE>
The lines are cut off and only the first 80 characters are shown as output. | Solution: The SELECT statement reads the whole line but visualizes only the first 80 characters. To solve this problem, you will have to include a FOR Statement and change the query into:

Problem Statement: Oracle columns of data type char will only allow strings to be assigned which have the exact length. Aspen SQLplus (SQLplus) trims strings off leading and trailing spaces. Therefore, even if the SQLplus variable is defined to be the same length as the Oracle column, the two may not be equal. | Solution: The reSolution is to change the Oracle column type to be VARCHAR or VARCHAR2, 'or' use the PAD function when making assignments.
For example
Update oracle.batchlog set batch=PAD(local.batch to 20);

Problem Statement: When a SELECT query involves the use of the AGGREGATE function, the GROUP BY statement often needs to be added. The result return does not return in the order in which the tag names are specified. In fact, it seems to have perform an ORDER BY in ascending order for the column specified first in the G... | Solution: This issue can be work around by declaring a TEMPORARY TABLE as can be seen in the screen capture below.
Instead of listing out the tag names in the Aspen SQLplus SELECT query, a SELECT query can be used to query from the TEMPORARY table.

Problem Statement: Real numbers with many significant digits (greater than 7), when displayed in Aspen SQLPlus, are displayed in exponential format, such as 1.23457e+007.
Precision is not lost, but this may not be how you want the number to be displayed. | Solution: To display the number in true numeric format, you can use the CAST USING statement to convert the value to CHAR, and display the value with a specific format. For example:
local x real;
x = 12345678.912;
write x;
write CAST(x as CHAR using 'f22.11');
Running this gives you:
1.23457e+007

Problem Statement: Prior to V6, when using the HISTORY table to request TEXT data from records such as IP_TextDef records, it would result in the message:
no rows selected | Solution: The History table can now take a parameter to indicate that the value should be returned as a character value. The value of the parameter is the maximum length (column size) of the value column.
E.g.
select ts,value from history(80) where name = 'TextRec1'
and ts between '30-jun-04 10:00:00' and '30-jun-04 10... |
Problem Statement: Is there a way using SQLplus to identify which record an external task is processing? | Solution: There are 2 functions that can retrieve this type of information. The first one is TASK_CURRENT.

The default name of the file is XOldestOKTags.txt located in the Aspen InfoPlus.21 Group200 folder... |
Problem Statement: This knowledge base article discusses how to print output generated from an SQLplus query to various printers on the network. | Solution: The SYSTEM command in SQLplus is usually used to call custom programs from within an SQLplus script. However, the SYSTEM command can also be used to call Windows DOS functions such as the 'PRINT' function. The PRINT function can thus be used in an SQLplus script to print a file to a printer on the network.

if ts1 like ts2 then
write 'Like';
else
write 'Not Like';
end
if ts1 = ts2 then
write 'Equal';
else
write 'Not Equal';
end
This query produces:

The default format for timestamp local variables is TS20, so using LIKE to compare timestamp local variables means that fract... |
Problem Statement: Why does this query not return a character length of 5? | Solution: SQLplus truncates character strings, but not variants. By declaring x as a variant, the character length is the expected result.

The DATABASE_SIZE function can be used with different parameters to find other u... |
Problem Statement: Sometimes it may only be necessary to see the first so many records of output instead of seeing them all. For example, you only need to see the first 3 records with the highest ip_graph_maximum and the tag name. | Solution: The easiest way to accomplish this is by using the MAX_ROWS SET statement as follows:
SET MAX_ROWS 3;
SELECT name, ip_graph_maximum FROM ip_analogdef
ORDER BY ip_graph_maximum DESC;
Your results would only contain 3 rows of data including the name and ip_graph_maximum (largest value first and so on). The ORDE... |
