| Character Semantics And Globalization in Oracle - Prevent storage problems associated with mutlibyte character sets by using character semantics when defining table columns. |
Sven said... when we didalter system set nls_length_semantics=char; we had to restart the engine, the next session had nls_length_semantics=byte again and the %char% ddl were 1 byte per character. So we decided to do: 1. explicitly assign char to %char% ddl columns 2. or alter session set nls_length_semantics = 'CHAR' ------------ Greetings |

Our DB NLS Params are as belowNLS_LANGUAGE AMERICAN NLS_TERRITORY AMERICA NLS_CURRENCY $ NLS_ISO_CURRENCY AMERICA NLS_NUMERIC_CHARACTERS ., NLS_CHARACTERSET UTF8 NLS_CALENDAR GREGORIAN NLS_DATE_FORMAT DD-MON-RR NLS_DATE_LANGUAGE AMERICAN NLS_SORT BINARY NLS_TIME_FORMAT HH.MI.SSXFF AM NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZR NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZR NLS_DUAL_CURRENCY $ NLS_COMP BINARY NLS_LENGTH_SEMANTICS BYTE NLS_NCHAR_CONV_EXCP FALSE NLS_NCHAR_CHARACTERSET UTF8 NLS_RDBMS_VERSION 9.2.0.4.0 Created a table as below CREATE TABLE SAMIR_UTF8_TEST( ID_TEST VARCHAR2(100 CHAR), TEST_DESC VARCHAR2(4000 CHAR) ); But when we try to add a MS-Word text (3916 chars) with MS-Word smart quotes it fails insetion/updation. Anything I am doing wrong??? |
Vadim said... I've tried:CREATE TABLE tab3 ( id NUMBER(10), description VARCHAR2(20 CHAR) ); NLS_LENGTH_SEMANTICS = BYTE Table is created, but What's wrong? |
Vadim said... Sorry, the table was created by SYS user.When I logged in by another user, all is OK. |
