Hi,
I need help in solving this issue.
' Ã… ' is the special character that needs to be obtained from select
query in the WMB flow.
U+00C5Ã…c3 85LATIN CAPITAL LETTER A WITH RING ABOVE
We captured the error in trace,
See the following messages for
details of the error.

Our WMB has 1208-UTF8 as CCSID
MySQL is LATIN-1
I tried this command in MySQL directly.Its not showing output
SELECT FLOW_REFERENCE as TBL_FLOW_REFERENCE, SOURCE_VALUE_C_1 as TBL_SOURCE_VALUE_C_1, SOURCE_VALUE_C_2 as TBL_SOURCE_VALUE_C_2, SOURCE_VALUE_C_3 as TBL_SOURCE_VALUE_C_3, SOURCE_VALUE_C_4 as TBL_SOURCE_VALUE_C_4, SOURCE_VALUE_C_5 as TBL_SOURCE_VALUE_C_5, XREF_TYPE_DESC as TBL_XREF_TYPE_DESC, CONVERT(TARGET_VALUE_C_1 USING utf8) as TBL_TARGET_VALUE_C_1 , TARGET_VALUE_C_2 as TBL_TARGET_VALUE_C_2, TARGET_VALUE_C_3 as TBL_TARGET_VALUE_C_3, TARGET_VALUE_C_4 as TBL_TARGET_VALUE_C_4, TARGET_VALUE_C_5 as TBL_TARGET_VALUE_C_5 FROM T_LOOKUP WHERE FLOW_REFERENCE='NEWHIRENATIONALITY' AND SOURCE_VALUE_C_1='Aland Islander' ;
But when I use the same command in WMB,during I am still getting Runtime error as Unconvertable character.
It would be really great help if someone could help me on this.
http://www-01.ibm.com/support/docview.wss?uid=swg21382185 -Same issue
fixed for ODBC connection in WMB7,8 for ORACLE.
But for MySQL,its not there.. |

For MySQL / ODBC connection, it is recommended using same setting for client and server in $MYSQL_HOME/my.cnf, e.g. when codepage is Latin-2:
| Code: |
[mysqld]
port=3306
socket=/tmp/mysql.sock
default-storage-engine=InnoDB
character-set-server=latin2
lower_case_table_names=1
sql_mode=ANSI_QUOTES
log_warnings=2
skip-name-resolve
query-cache-size=16M
[client]
default-character-set=latin2
port=3306
socket=/tmp/mysql.sock

We found one more solution for this problem..
Steps followed as below,
1)We changed the CCSID of the table column for which UTF-3 conversion is required,
ALTER TABLE T_TABLE MODIFY TARGET_FIELD_1 char(100) CHARACTER SET utf8;
2)In WMB esql code,for Select query,the column value is picked up as Hexa value and then CAST to BLOB ,BLOB to CHAR done as below,
SELECT ....HEX(TARGET_FIELD_1) as TBL_TARGET_VALUE_C_1,
....
SET Environment.Variables.FlowSpecific.TARGET_VALUE_C_1=CAST(CAST(Environment.Variables.FlowSpecific.TARGET_VALUE_C_1 AS BLOB )AS CHAR CCSID 1208 );
This is working fine...
But even after changing the Table column to UTF-8 ,still in WMB we have to pick up as hex and then from hex to blob and blob to char.
Any idea why we have to do esql level changes also?Without making this change in esql,just with alter table column is not working... |

That may well be because the internal representation is CCSID 1200 and not UTF-8. So in order to insert into the DB you first have to convert to UTF-8...
Have fun

Sorry, but it seems terrible and not really sustainable for the future.
Please check the codepage settings at MySQL and MySQL/ODBC level first, as it was mentioned in my earlier comment. If the problem persist, you can check the ODBC connector if you switch its trace on.
And please give more information about versions of WMB, ODBC, etc. |

WMB internal representation is 1208 which is actually UTF-8.Correct me if I am wrong in understanding your statement.

We are using Select query in WMB.. |

You should check your sources, because that is not correct. Maybe you are getting confused between Unicode and UTF-8 ( not the same thing).
In the message tree, all CHARACTER data is in CCSID 1200 ( UTF-16, platform-dependent byte order ). The parser converts from the input document CCSID to UTF-16 when reading. It converts from UTF-16 to the specified output CCSID ( OutputRoot.Properties.CodedCharSetId ) when writing.

Thanks...
So ,if we use ALTER table for UTF16 as below,
ALTER TABLE T_TABLE MODIFY TARGET_VALUE_C_1 char(100) CHARACTER SET utf16;
We will be directly able to read the field values without any conversions from Hex->BLOB->CHAR..
Correct me if I am wrong.. |
