I have a firebird database that I need to recreate. It contains an external UDF function. I made an SQL dump of the DB structure using IB Expert:
DECLARE EXTERNAL FUNCTION LPAD
CSTRING(255),
INTEGER,
CSTRING(1)
RETURNS CSTRING(255) FREE_IT
ENTRY_POINT 'IB_UDF_lpad' MODULE_NAME 'ib_udf'
However, I get an error when I run the query:
Invalid token.
Dynamic SQL Error.
SQL error code = -104.
Token unknown - line 1, column 27.
'LPAD'.
I'm using Firebird 2.1.1 on Windows. Does anyone know what might be the problem?
try this
DECLARE EXTERNAL FUNCTION "LPAD"
CSTRING(255),
INTEGER,
CSTRING(1)
RETURNS CSTRING(255) FREE_IT
ENTRY_POINT 'IB_UDF_lpad' MODULE_NAME 'ib_udf'

I'm new to using the Firebird Database Management System and I need to use the ENCRYPT function in my project.
In my project I have been trying to use the following statement for testing:
INSERT INTO state (name)
values (ENCRYPT('MG' using aes mode cbc key 'password' iv '01234567'));
But I have been getting the following Firebird error:
Statement failed, SQLSTATE = 42000
Dynamic SQL Error
-SQL error code = -104
-Token unknown - line 1, column 43
-(
I accessed the documentation and the only example I found there was:
select encrypt('897897' using sober128 key 'AbcdAbcdAbcdAbcd' iv '01234567')
from rdb$database;
The structure of the function is:
ENCRYPT (input
USING <algorithm> [MODE <mode>]
KEY key
[IV iv] [<ctr_type>] [CTR_LENGTH ctr_length]
[COUNTER initial_counter] )
I already tried several modifications in the instruction, but I didn't succeed. Could anyone help me with fixing this problem?
why it shows the error under the > when i am making the trigger in oracel sql developer
2 things: use > instead of >, and := is extraneous.
How do I compile a new function created inside a package in plsql, to see syntactical error and so on
You can't compile a single function - compile the whole package.
If your concern is about invalidating the whole package in case that function has errors, then
create a standalone function (i.e. outside of the package)
debug it
once it is OK (doesn't have syntax errors, returns result as expected), include it into the package
In addition to #Littefoot's advise I'd say: use a proper GUI. Oracle has a free tool called sql developer. It has a great interface for editing database objects (packages/functions/procedures/triggers). It highlights errors and is very well documented (https://www.thatjeffsmith.com/sql-developer/). Note that is does not point out syntax errors - but once you're a bit used to working with pl/sql they become obvious very quickly.
In Oracle, after compiling a procedure/function/package. If there is an error then the command will return with the message:
ORA-24344: success with compilation error
You can then use:
SHOW ERRORS
or
SELECT * FROM USER_ERRORS;
or, for example, for errors with packages in a specific schema:
SELECT *
FROM ALL_ERRORS
WHERE owner = 'SCHEMA_NAME'
AND type IN ( 'PACKAGE', 'PACKAGE BODY');
Which will list the errors (complete with line numbers and error messages) and you can then debug the procedure/function/package and recompile it.

I've got a Hive SQL script/action as part of an Oozie workflow. I'm doing a CREATE TABLE AS SELECT to output the results. I want to name the table using the username plus an appended string (e.g. "User123456_output_table"), but can't seem to get the correct syntax.
set tablename=${hivevar:current_user()};
CREATE TABLE `${hiveconf:tablename}_output_table` AS SELECT ...
That doesn't work and gives:
Error while compiling statement: FAILED: IllegalArgumentException java.net.URISyntaxException: Relative path in absolute URI: ${hivevar:current_user()%7D_output_table
Or changing the first line to set tablename=${current_user()}; starts running the SELECT query but eventually stops with:
Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.apache.hadoop.hive.ql.metadata.HiveException: [${current_user()}_output_table]: is not a valid table name
Or changing the first line to set tablename=current_user(); starts running the SELECT query but eventually stops with:
Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.apache.hadoop.hive.ql.metadata.HiveException: [current_user()_output_table]: is not a valid table name
Alternatively, is there a way to pass the username from the Oozie workflow via a parameter?
I'm using Hue to do all this rather than the command line.
Thanks
This is wrong: set tablename=${hivevar:current_user()}; - it will not be resolved and substituted as is.
Hive does not calculate variables before substitution, it substitutes them as is, all functions in variables are NOT calculated. variables are just text replacement.
This:
set tablename=current_user();
CREATE TABLE `${hiveconf:tablename}_output_table` ...
gets resolved as
CREATE TABLE `current_user()_output_table` ...
And functions are not supported in table names, it will not work this way.
The solution is to calculate functions outside the script and pass them as parameters.

Good day!
I get this error:
SQL STATE 37000 [Microsoft][ODBC Microsoft Access Driver] Syntax Error
or Access Violation, when trying to run an embedded SQL statement on
Powerscript.
I am using MsSQL Server 2008 and PowerBuilder 10.5, the OS is Windows 7. I was able to determine one of the queries that is causing the problem:
SELECT top 1 CONVERT(DATETIME,:ls_datetime)
into :ldtme_datetime
from employee_information
USING SQLCA;
if SQLCA.SQLCODE = -1 then
Messagebox('SQL ERROR',SQLCA.SQLERRTEXT)
return -1
end if
I was able to come up with a solution to this by just using the datetime() function of PowerBuilder. But there are other parts of the program that is causing this and I am having a hard time in identifying which part of the program causes this. I find this very weird because I am running the same scripts here in my dev-pc with no problems at all, but when trying to run the program on my client's workstation I am getting this error. I haven't found any differences in the workstation and my dev-pc. I also tried following the instructions here, but the problem still occurs.
UPDATE: I was able to identify the other script that is causing the problem:
/////////////////////////////////////////////////////////////////////////////
// f_datediff
// Computes the time difference (in number of minutes) between adtme_datefrom and adtme_dateto
////////////////////////////
decimal ld_time_diff
SELECT top 1 DATEDIFF(MINUTE,:adtme_datefrom,:adtme_dateto)
into :ld_time_diff
FROM EMPLOYEE_INFORMATION
USING SQLCA;
if SQLCA.SQLCODE = -1 then
Messagebox('SQL ERROR',SQLCA.SQLERRTEXT)
return -1
end if
return ld_time_diff
Seems like passing datetime variables causes the error above. Other scripts are working fine.
Create a transaction user object inherited trom transaction.
Put logic in the sqlpreview of your object to capture and log the sql statement being sent to the db.
Instantiate it, connect to the db, and use it in your embedded sql.
Assuming the user gets the error you can then check what was being sent to the db and go from there.
The error in your first statement should be the second parameter to CONVERT function.
It's type is not a string, it's type is an valid expression
https://learn.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql
So I would expect that your
CONVERT(DATETIME,:ls_datetime)
would evaluate to
CONVERT(DATETIME, 'ls_datetime')
but it should be
CONVERT(DATETIME, DateTimeColumn)
The error in your second statement could be that you're providing an wrong datetime format.
So please check if your error still occurs when you use this function
https://learn.microsoft.com/en-us/sql/t-sql/statements/set-dateformat-transact-sql
with the correct datetime format you're using
