I am working on Java coding..
Trying to set author value:
XXX.setStatusValue(YYY.AUTHOR.toString());
When trying to insert this value in database,
Here is the error I get:
too long for column 'status_value' at row 1
I have not designed the tables, just using the existing ones.
Here is the error i get: too long for column 'status_value' at row 1
The error says it all.
The value you are trying to insert into the database is larger than the maximum length allowable in the field in the table.
Either insert a shorter string, or make the field in the database longer.
I think all database columns have it's own length and you cannot set value have bigger than that. If you don't know how long is your column length, just try insert value with increase length (example from 1 to 200). When error occurs, you will know exactly length of column.

Given this PostgreSQL table with a fixed length array column :
CREATE TABLE test (
id integer,
values integer[4],
);
Will JOOQ code generation create a java constant or method that provides the max number of elements that can be stored in the values column (i.e. 4)?
After reading through JOOQ documentation on code generation and support for SQL arrays, I couldn't find anything specific about fixed length arrays. Also, nothing jumps out at me in the generated code that provides this information.
No, version 3.9 of jOOQ doesn't know any fixed size or size limit of a database array (neither with PostgreSQL array types nor with Oracle VARRAY types).
I have registered feature request #5932 for this.
I asked this question in part because I was worried about array overruns in the PostgreSQL database. After researching a way to use straight SQL to determine the size constraint, I noticed the PostgreSQL ARRAY documentation makes the statement :
As before, however, PostgreSQL does not enforce the size restriction in any case.
Based on that statement, it would appear using the array constraint to enforce size is not necessary since all array columns appear to be treated as variable length. So even if one could retrieve the PostgreSQL array size constraint through JOOQ, Straight SQL, or any other means, why bother?
I have one value as string say '1'.
I need to put this in column whose data type is bit.
I am trying to update this value using wraaper class as Boolean by typecasting(e.g. like (Boolean)map.key("key_name") as well as by parsing like (Boolean.parseBoolean(map.key("key_name").toString())
But its not updating. I am using MS sql server 2008.
BIT datatype can only store either 0 or 1. It can't store BOOLEAN values that is TRUE or FLASE. Here you will need to convert you TRUE or FALSE value to 1 or 0 respectively to store it into BIT column.
I am working with a program that i have a record for every user. My users have a property with key, PhoneNumber , and its value is an array of strings, [454457,897356]. For example if i wanted to use cypher query:
Start n=node(1)
Return n
It returns 1 record for my node(one row) that the value of column PhoneNumber is an array.
But i want to have record numbers according to the number of values in my array, means that for my example, the query returns 2 records(2 rows) and all of its attributes be the same but in the PhoneNumber column one of them has the value 454457 and the other has the value 897356. Is any way to do that? do i change my cypher query or make some changes in my java code?
Thanks.
There is no way to do that yet, within Cypher. I've submitted a request for it, though:

I'm trying to write a JTable that takes the data from a ResultSet and uses that to create a dynamic sized table with appropriate column names and row data values from the ResultSet but I can't get JDBC to get the column names for me dynamically.
I know my select statement is good! I can print the results out easily with my ResultPrinter class that I wrote but I can't seem to get the column names for some reason.
The code: http://pastebin.com/SSNdCkNu
The output:
Connected to DB!
SNUM, SNAME, STATUS, CITY, SUPPLIERS_ID_SEQ // printed by static Suppliers class
Columns: 5 // result set shows there are 5 valid columns as expected
Exception in thread "main" java.sql.SQLException: Invalid column index: getValidColumnIndex

JDBC column indexes start from 1 and not 0. As far as possible, it is better to retrieve data using column names to avoid hard dependency on the order of columns in the results.
Column index starts by 1. So increase your variable pointing column variable by 1.
I have a field with varchar(100) in mysql, I want to store first 100 characters because my data length is 200 characters(ignore last 100 character).I doesn't want to change my source code. Which is possible in MS-Access and MS Server but I want to do this in mysql.
I am applying this in java with hibernate, means I am not writing insertion code for this. Here I am just using save() method and its throwing "Large data".
I have got Exception-
Caused by: java.sql.BatchUpdateException: Data truncation: Data too long for column 'FBUrl' at row 1

Note: An hour after the below, the question was edited with a substantial change. This answer answered the question as it was originally, but doesn't address the edited version.
You can use substring:
INSERT INTO MyTable (Myfield) values (SUBSTRING('long string', 1, 100))
The pos parameter starts at 1 (oddly), and it's okay if the len parameter is larger than the length of what you're actually inserting.
You can use SUBSTRING() to trim inserts:
INSERT INTO table (column) VALUES (SUBSTRING("your data...", 1, 100))
try this
SELECT INSERT('your string', 0, 100, '');
REFERENCE
The only way to do it without changing the source code is to fiddle with the configuration of the MySQL server. More specifically, the sql_mode variable:
http://dev.mysql.com/doc/refman/5.1/en/server-sql-mode.html
I believe you have to set STRICT_TRANS_TABLES:
For STRICT_TRANS_TABLES, MySQL
converts an invalid value to the
closest valid value for the column and
insert the adjusted value. If a value
is missing, MySQL inserts the implicit
default value for the column data
type. In either case, MySQL generates
a warning rather than an error and
continues processing the statement.
Implicit defaults are described in
Section 10.1.4, “Data Type Default
Values”.
However, it's important to note that this setting will affect many other things. The only reason I see not to change the source code is that you don't have access to it, and in such case you can probably just enlarge the DB column.
