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.

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.
I am trying to update the records in database according to data read from an Excel sheet. I have more than 50 columns in db whose column names are stored in an array columnNames[].
I use following code to create the Sql query.
String sqlUpdate= "Update "+tableName+
" set "+columnNames[0]+"=?";
for (int i=1;i<columnCount;i++)
{
sqlUpdate= sqlUpdate+","+columnNames[i]+"=?";
}
sqlUpdate= sqlUpdate+
" where demand_id=?";
the equivalent query obtained to printing it on console is :
Update fulfillment_plan set DEMAND_ID=?,SBU=?,PROJ_DOMAIN=?,JOBCODE=?,INDENT_STATUS=?,JC_CREATED_ON=?,PROJECT_NAME=?,CUSTOMER_NAME=?,GROUP_CUSTOMER=?,US_DEMANDS=?,SUITE_NAME=?,ROLE_NAME=?,LOCATION=?,COUNTRY=?,GEO=?,AREA=?,OPEN_POS=?,PRODUCT=?,DEMAND_TYPE=?,POSITIONS_TO_FULFILL_Q4=?,FULFILLMENT_PLAN_Q4=?,TA_STATUS_Q4=?,POSITIONS_TO_FULFILL_Q3=?,FULFILLMENT_PLAN_Q3=?,TA_STATUS_Q3=?,POSITIONS_TO_FULFILL_Q2=?,FULFILLMENT_PLAN_Q2=?,TA_STATUS_Q2=?,POSITIONS_TO_FULFILL_Q1=?,FULFILLMENT_PLAN_Q1=?,TA_STATUS_Q1=?,NET_ADD_TYPE=?,ESSENTIAL_SKILL=?,SUITE_SKILLS=?,ADDITIONAL_SKILLS=?,POSITIONS_WITH_PROPOSALS=?,POSITIONS_WITHOUT_PROPOSALS=?,DEM_ST_DATE=?,OVER_DUE_STATUS=?,OVERDUE_DAYS=?,LEAD_TIME_DAYS=?,LEAD TIME BUCKET=?,DEM_END_DATE=?,CREATED_ON=?,INDENT_CREATED_ON=?,EBD=?,OPPORTUNITYID=?,LOAD_DATE=?,PROJECT_NUMBER=?,CUSTOMER_NO=?,CUSTOMER_SUB_GEO=?,DEMAND_STATUS=?,ENGAGEMENT_TYPE=?,INVOICE_TYPE=?,INDENT_CLASSIFICATIONS=?,PROJ_STAT=?,EFD_SLA=?,RM_EMP_NAME=?,MONTH=?,QUARTER=?,YEAR=?,ACCOUNT_ID=?,ACCOUNT_TEXT=?,STATUS=? where demand_id=?
Then i have set the values to the '?' and on executing the above prepared statement in am getting the "missing equal sign" error. I have been looking into it for around 3 hours now and am not able to solve it. Kindly help.
I suspect this is due to the LEAD TIME BUCKET column name, which should either have underscores (like the other column names) or be escaped somehow - the spaces within the column name are causing the error. It would be better to have underscores in order to be consistent with your other columns, and to make the SQL simpler.
(I'd also suggest adding spaces within your SQL - e.g. one after every comma - so that the SQL can be reformatted in a text editor by line-breaking on spaces, making it easier to read. I'd have more whitespace in the Java code too, but that's clearly a matter of personal/team preference.)
I'm converting (or trying to) an Ms AccessDB into derby.
When I extract the data from certain varchar / text / memo field from access they are filled with apostrophe, and mathematical symbols (percent, less than etc), and possible foreign characters
I need to keep these and I test for them so as I can use an 'escape sequence' to ensure they get put into the database.
However for now I am unable to get the data into the DB without it failing on these fields. When the SQL fails I output the SQL string, and cut and past it into ij. Then I modify just the first record, and it is always these characters that cause me grief.
I've tried to modify the strings by surrounding with "double quote marks" but that just gives a different error (stating that it has 'enounterd """ at line1 column x' which is always the first occurance of the double quote).
I haven't found a setting in derby to alter the behaviour for strings, yet. Is there one?
I have also tried to set the SQL statment to a preparedStatement then use the {call preparedStatement} again this fails also. I can't use the {escape "escape char} in a normal statment as derby just says incorrect syntax at me.
How do others manage to get user content with strange characters into a field in derby?
Do I need to change my field into a CLOB or something other than varchar / long Varchar?
Are my problems being caused by using the wrong characteset (eg iso rather UTF-8), how do I tell what it is, how to change it?
Below is a sample of the SQL insert that fails when I send it to derby (via my JAVA 'programme')
insert into S1.SORTIEDESSAI (OBS, DATEDUSORTIE, CONTREINDIC, FIN,
PDEVU, REFUS, INVDECISN, ADMIN, MOTIF_DE_LA_SORTIE, NOMVALIDEE,
DATEVALIDEE) values ('"0001/0001"' , '2007-07-15' , false , true ,
'"null"' , '"null"' , '"null"' , '"null"' , '"2. FIN DE L’ESSAI"' ,
'"DR SIMON"' , '2011-04-19' )
Note:
Actually I look at the above and notice that the order of columns names isn't good? It was OK yesterday, not sure why it would have changed? something to do with Access returning the column names in a random order from the resultSetMetaData, which would be a surprise.
for now I recomend any further answers to hold off whilst I sort this problem out, OK solved that problem, do I need to set another question about this behaviour....
Back to the main thread...
Ok as you can see on my SQL statement I have wrapped any varchar fields in double quotes. This always fails (even directly through ij). help help help...
I'm not quite sure what your question is, but in general you can input these characters by using a PreparedStatement of the form: INSERT INTO tablename (columnname) values (?), and then using the PreparedStatement.setString() method to supply your character data for that column.
I am trying to insert string-values larger than 5500 characters into a MSSQL 2008 database. I get the error
String or binary data would be truncated.
when I try to insert these values even though the data type of the column is declared nvarchar(max). Is there a cap on the string-size that I can enter? If so, what would be a solution to this problem?
EDIT
When i manually enter the data via mgmt studio it works. However, I'm performing the updates via JDBC-driver & prepared statements.
My query is of the form:
UPDATE table SET columnX = value1 WHERE columnX = value2;
I add this statement to a batch, and once every 1000 statements I execute them.
value1 in this case contains a large amount of characters.
columnX is definitely defined as nvarchar(max)
Microsoft encourages us to use the SQLServerPreparedStatement to modify large-value-types like varchar(max).
http://msdn.microsoft.com/en-us/library/ms378813.aspx
You could also use a stored procedure to solve the problem, that is what I did, when I had similar problems with JDBC/Pentaho.
You could write a stored procedure on the sql-server that fulfills the task. And just call that stored procedure from your Java-code.
I hope that helps!
I'm having a little trouble using Hibernate with a char(6) column in Oracle. Here's the structure of the table:
CREATE TABLE ACCEPTANCE
(
USER_ID char(6) PRIMARY KEY NOT NULL,
ACCEPT_DATE date
);
For records whose user id has less than 6 characters, I can select them without padding the user id when running queries using SQuirreL. I.E. the following returns a record if there's a record with a user id of "abc".
select * from acceptance where user_id = "abc"
Unfortunately, when doing the select via Hibernate (JPA), the following returns null:
em.find(Acceptance.class, "abc");
If I pad the value though, it returns the correct record:
em.find(Acceptance.class, "abc ");
The module that I'm working on gets the user id unpadded from other parts of the system. Is there a better way to get Hibernate working other than putting in code to adapt the user id to a certain length before giving it to Hibernate? (which could present maintenance issues down the road if the length ever changes)
That's God's way of telling you to never use CHAR() for primary key :-)
Seriously, however, since your user_id is mapped as String in your entity Hibernate's Oracle dialect translates that into varchar. Since Hibernate uses prepared statements for all its queries, that semantics carries over (unlike SQuirreL, where the value is specified as literal and thus is converted differently).
Based on Oracle type conversion rules column value is then promoted to varchar2 and compared as such; thus you get back no records.
If you can't change the underlying column type, your best option is probably to use HQL query and rtrim() function which is supported by Oracle dialect.
How come that your module gets an unpadded value from other parts of the system?
According to my understanding, if the other part of the system don't alter the PK, they should read 6 chars from the db and pass 6 chars all along the way -- that would be ok. The only exception would be when a PK is generated, in which case it may need to be padded.
You can circumvent the problem (by trimming or padding the value each time it's necessary), but it won't solve the problem upfront that your PK is not handled consistently. To solve the problem upfront you must eiher
always receive 6 chars from the other parts of the module
use varchar2 to deal with dynamic size correctly
If you can't solve the problem upfront, then you will indeed need to either
add trimming/padding all around the place when necessary
add trimming/padding in the DAO if you have one
add trimming/padding in the user type if this works (suggestion from N. Hughes)
