I need to move a Substring into a Timestamp Field. But if I compile it, I get the Error Number
RNF7416 - The types of operands on the right and left sides of the expression in the EVAL operation do not match.
The Code:
MONITOR;
TSTPFIELD = %SUBST(NEWDS:01:26);
ON-ERROR;
TSTPFIELD = %TIMESTAMP();
ENDMON;
Do someone know how to convert the %SUBST(NEWDS:01:26) to Timestamp?
I believe this should do
tstamp = %timestamp(%SUBST(NEWDS:01:26))
You need to cast it to timestamp

I have an integer field coming and I want to extract the first digit from the field, how can I do it. I cannot cast the field since the data is coming from a dataset, is there a way to extract first digit from the transformer stage in IBM datastage?
Example:
Input:
ABC = 1234
Output: 1
Can anyone please help me with the same?
Thanks!
Use a transformer, define a stage variable as varchar and use this formula to get the substring
ABC[1,1]
Alternatively you can also convert your numeric value by using the DecimalToString
You CAN convert to string within the context of your expression, and back again if the result needs to be an integer.
AsInteger(Left(ln_jn_ENCNTR_DTL.CCH,1)
This solution has used implicit conversion from integer to string. It assumes that the value of CCH is always an integer.
I would say- if ABC has type int, you can define a stage variable of type char having length 1.
then you need to convert Number to string first.And use Left function to extract the first char.
Left(DecimalToString(ABC),1).
If you are getting ABC as string, you can directly apply left function.
You can first define a stage variable (name say SV) of varchar type (to convert input integer column into varchar) :
Stage variable definition
Now assign the input integer column to stage variable SV and derive output integer column as AsInteger(SV[1,1]) : Column definition
i.e. input integer => (Type conversion to varchar) Stage variable => Substring[1,1] and Substring Conversion to Integer using AsInteger.
DecimalToString is an implicit conversion, so all you need is the Left() function. Left(MyString,1)
In my xquery i have the condition to check if (SP_TYPE_CD!="") and (max of the EndDate) in an array and return the EndDate that meets this condition

Unless your query is schema-aware, the #endDate attribute (after atomization) will be xs:untypedAtomic, and the max() function attempts to convert xs:untypedAtomic values to dates. You need to tell the query processor to treat the values as dates, which you can do either by making your query schema-aware, or (more simply) by an explicit cast:
fn:max($SA_INFO_LISTRow/#EndDate/xs:date(.))
However, there are other problems with your query. This condition:
if (($SA_INFO_LISTRow/#SP_TYPE_CD) and fn:max($SA_INFO_LISTRow/#EndDate))
(when corrected) is simply asking whether a maximum date exists, and if there are any dates at all, then there will be a maximum, so this is fairly meaningless.
Also, you say you are looking for entries where #SP_TYPE_CD is not equal to "", but your code is looking for all entries where this attribute exists, regardless of its value.
I'm guessing that you actually want the maximum end date of all entries where #SP_TYPE_CD is not equal to "", and that would be (replacing your entire query)
<ns1:date>
{max(//SA_INFO_LISTRow[#SP_TYPE_CD != '']/#EndDate/xs:date(.))}
</ns1:date>
I am attempting to run a simple UPDATE script on an integer field, whereby the trailing 2 numbers are "kept", and the leading numbers are removed. For example, "0440" would be updated as "40." I can get the desired data in a SELECT statement, such as
SELECT RIGHT(field_name::varchar, 2)
FROM table_name;
However, I run into an error when I try to use this same functionality in an UPDATE script, such as:
UPDATE schema_name.table_name
SET field_name = RIGHT(field_name::varchar, 2);
The error I receive reads:
column . . . is of type integer but expression is of type text . . .
HINT: You will need to rewrite or cast the expression
You're casting the integer to varchar but you're not casting the result back to integer.
UPDATE schema_name.table_name
SET field_name = RIGHT(field_name::TEXT, 2)::INTEGER;
The error is quite straight forward - right returns textual data, which you cannot assign to an integer column. You could, however, explicitly cast it back:
UPDATE schema_name.table_name
SET field_name = RIGHT(field_name::varchar, 2)::int;
1 is a digit (or a number - or a string), '123' is a number (or a string).
Your example 0440 does not make sense for an integer value, since leading (insignificant) 0 are not stored.
Strictly speaking data type integer is no good to store the "trailing 2 numbers" - meaning digits - since 00 and 0 both result in the same integer value 0. But I don't think that's what you meant.
For operating on the numeric value, don't use string functions (which requires casting back and forth. The modulo operator % does what you need, exactly: field_name%100. So:
UPDATE schema_name.table_name
SET field_name = field_name%100
WHERE field_name > 99; -- to avoid empty updates
I am joining the two tables using the query below:
update campaign_items
set last_modified = evt.event_time
from (
select max(event_time) event_time
,result
from events
where request = '/campaignitem/add'
group by result
) evt
where evt.result = campaign_items.id
where the result column is of character varying type and the id is of integer type
But the data in the result column contains digits(i.e. 12345)
How would I run this query with converting the type of the result(character) into id
(integer)
Well you don't need to because postgresql will do implicit type conversion in this situation. For example, you can try
select ' 12 ' = 12
You will see that it returns true even though there is extra whitespace in the string version. Nevertheless, if you need explicit conversion.
where evt.result::int = campaign_items.id
According to your comment you have values like convRepeatDelay, these obviously cannot be converted to int. What you should then do is convert your int to char!!
where evt.result = campaign_items.id::char
There are several solutions. You can use the cast operator :: to cast a value from a given type into another type:
WHERE evt.result::int = campaign_items.id
You can also use the CAST function, which is more portable:
WHERE CAST(evt.result AS int) = campaign_items.id
Note that to improve performances, you can add an index on the casting operation (note the mandatory double parentheses), but then you have to use GROUP BY result::int instead of GROUP BY result to take advantage of the index:
CREATE INDEX i_events_result ON events_items ((result::int));
By the way the best option is maybe to change the result column type to int if you know that it will only contain integers ;-)
When running the following the query.select * from surgicals where to_char(dt_surgery ,'DD-MM-YYYY' ) = to_char('12-02-2012','DD-MM-YYYY');
the error coming as 'SQL state 42725: ERROR: function to_char(unknown, unknown) is not unique'
How to run above select query?
You probably mean to_char('12-02-2012'::date, 'DD-MM-YYYY'). to_char cannot convert a plain string to string. Still, it does not seem to make sense, you need one of these two, depending on the format of your date constant (which cannot be determined from the actual example date you provided):
select * from surgicals where to_char(dt_surgery ,'DD-MM-YYYY' ) = '12-02-2012';
select * from surgicals where to_char(dt_surgery ,'MM-DD-YYYY' ) = '12-02-2012';
The wrongness here is that you're doing string comparison of dates. Use date/time math, which can take into account fun things like time zones etc. and still get it right.
Maybe this is what you need:
SELECT *
FROM surgicals
WHERE date_trunc('day', dt_surgery) = '2012-02-12'
;
