I am not sure if its the BizTalk error, thought I will check. I am trying to insert blank spaces in to the Oracle Table through the scripting functions
public string GetMXValue()
{
return " ";
}
So it returns 32 blank spaces to insert in to a field in Oracle Table. But we get an error
Send Port. Details:"Microsoft.ServiceModel.Channels.Common.TargetSystemException: ORA-01400: cannot insert NULL into ("DEVLAW"."GLTRANSREL"."MX_VALUE_02")
I am doing the right way to insert the blankspaces? I even tried using the String functiods and passed 32 blankspaces. Are black spaces treated as NULL in Oracle?
The field exists in the table

I am getting "JdbcSQLSyntaxErrorException: Column "REAL" not found" exception on inserting a record in the H2 Db table from an Springboot project.
My query is:
INSERT INTO `bharatqr_provider_config` (`id`, `provider_name`, `provider_base_url`, `provider_username`, `provider_password`, `provider_key`, `status`, `created_by`, `created_time`, `lock_id`, `modified_by`, `modified_time`, `timezone`, `auto_check_status_enabled`, `upi_check_status_enabled`,`terminal_type`,`qr_type`) VALUES (1,'HDFC', 'http://localhost:6061','','','','ACTIVE','me','2017-12-06 15:23:42',1,'me', '2017-12-06 15:23:42','IST', 0, 1,"REAL","INTERNAL"), (2,'DUMMY','http://localhost:6061','me','me','me','ACTIVE','me', '2018-01-10 12:24:03',1,'me','2018-01-10 12:24:03', NULL, 0, 0,"NONE","INTERNAL");
From the exception It's saying that Column "REAL" not found", But "REAL" is not the column name it's a value which have to insert in the column terminal_type.
"REAL" and "INTERNAL" are not values, they are identifiers in every standard-compliant database system.
Character string literals in SQL are surrounded by single quotes, you need to write them as 'REAL' and 'INTERNAL'.
Am trying execute a sql query on oracle database and inserting the result into another table, for my trial am just performing a simple query as
SELECT 1 AS count
FROM dual
and trying to insert that into a single column table which has the name COUNT.
The content of the record on Nifi seems to be as follows
[
{
"COUNT" : "1"
}
]
but the logs keeps throwing the error
due to java.sql.SQLDataException:
None of the fields in the record map to the columns defined by
the schema_name.table_name table:
any ideas ?
I believe you get that same error message if your table name doesn't match. The Translate Field Names property only translates the fields (columns), not the table name. Try specifying the schema/table in uppercase to match what Oracle is expecting.
I am trying to replace all of the NULL values to 0 in a column of a big table in HIVE.
However, every time I try to implement some code I end up generating a new column to the table. The column I am trying to change/modify still exists and still has the NULL values but the new column that is automatically generated (i.e. _c1) is what I want the column I am trying to modify, to look like.
I tried to run a COALESCE but that also ended up generating a new column. I also tried to implement a CASE WHEN, but the same results ensued.
Select *,
CASE WHEN columnname IS NULL THEN 0
ELSE columnname
END
from tablename;
Also tried
SELECT coalesce(columnname, CAST(0 AS BIGINT)) FROM tablename
I would just like to update the table with the other columns being as is but the column I want to modify still has its original name but instead of NULL values it has 0's that replaced them.
I don't want to generate a new column but modify an existing one.
How should I do that?
Use insert overwrite .. option.
insert overwrite table tablename
select c1,c2,...,coalesce(columnname,0) as columnname
from tablename
Note that you have to specify all the other column names required in select.
I have a create statement like
CREATE TABLE temp_tbl (EmpId String,Salary int);
I would like to insert an employee id and a blank value into table.
So What I have done is
insert overwrite table temp_tbl select '013' as EmpId,'' as Salary from tbl;
hive> select * from temp_tbl;
OK
013 NULL
But expected result is
hive> select * from temp_tbl;
OK
013 NULL ---> Blank instead of NULL
Also tried with "". Still I get it as NULL instead of blank
3.Tried to create table with serialization property
CREATE TABLE temp_tbl (EmpId String,Salary int) TBLPROPERTIES ('serialization.null.format' = '');
That too didn't change NULL value to blank.
What can be the workaround for the same.
Use Case while selecting the data.
Select
(CASE
WHEN columnName is null THEN ''
ELSE columnName
END) as 'Result' from temp_tbl;
All types except strings/varchar/char and some complex types like array, in Hive cannot be blank, only NULL is possible. Empty string '' is quite normal value of type String. You can produce empty array() as well (Array with zero size).
As a workaround, you can use some predefined values which are not normally in your data to represent some special numeric values, like -99999. Alternatively you can store your numeric values in a String column, in such case you will be able to have empty values in it. But it's not possible to assign (cast) empty strings to numeric types, because such empty value is not allowed.
If you try to assign empty string to numeric column or cast to numeric type, the result will be the same as if you are converting non-numeric string to numeric - NULL (in Hive if not possible to cast, it returns NULL) or get java.lang.NumberFormatException in Java.
Knowing that datatype Int can be either NULL or integer , I'd think of how to work around the problem.
I have the impression that 0 can do the job. Why can it not?
If 1 is not ideal, why not create a new temp_employees_with_no_salary table?
If 2 is not ideal, can you afford to change the datatype of temp_tbl.Salary from Int to String, then use CAST(Salary AS INT) to work with it?
Can any one help How to find out which columns and rows has Extended ASCII Codes in the table (EX:-Ž,™,Ù)?
Examples
jacob\Û
=pal®
I need query some thing like Select * from table to get Extended ASCII
Thanks For help
You can try with:
SELECT *
FROM mytable
WHERE mycolumn<>CONVERT(mycolumn, 'US7ASCII');
You can use TRANSLATE to remove all valid characters from the string, so only the special characters remain. Then check for NULL (as an empty string is NULL in Oracle; don't use length, for the length will not be 0 as one would expect but null):
select name
from mytable
where TRANSLATE(name, '®ABCDEFG...abc...', '®') is not null;
You will have to put all valid characters in the string where I simply put '...'.
I used one special character to replace itself as you see, because otherwise the replacement string had to be empty, but empty means null in Oracle and translate doesn't work with null.
(Yes, that empty string is null thing in Oracle is really a nuisance.)
